Gene therapy in hemophilia advances with big drops in patient bleeding rates - STAT

PHILADELPHIA When doctors saw the report on Bill Ludwigs bone-marrow biopsy, they thought it was a mistake and ordered the test repeated. But the results came back the same: His lethal leukemia had been wiped out by an experimental treatment never used in humans.

We were hoping for a little improvement, remembers the 72-year-old retired New Jersey corrections officer, who had battled the disease for a decade. He and his oncologist both broke down when she delivered the good news in 2010. Nobody was hoping for zero cancer.

The pioneering therapy with Ludwig and a few other adults at the University of Pennsylvania hospital paved the way for clinical trials with children. Six-year-old Emily Whitehead, who was near death, became the first pediatric recipient in 2012. Like Ludwig, she remains cancer-free.

Such results are why the treatment is on track to become the first gene therapy approved by the Food and Drug Administration. An FDA advisory committee will decide Wednesday whether to recommend approval of the approach, which uses patients own genetically altered immune cells to fight blood cancers.

If the panel gives the nod, the agency probably will follow suit by the end of September. That would open the latest chapter in immunotherapy a true living drug, says Penn scientist Carl June, who led its development.

The CAR T-cell treatment, manufactured by the drug company Novartis, initially would be available only for the small number of children and young adults whose leukemia doesnt respond to standard care. Those patients typically have a grim prognosis, but in the pivotal trial testing the therapy in almost a dozen countries, 83 percent of patients went into remission. A year later, two-thirds remained so.

And childhood leukemia is just the start for a field that has attracted intense interest in academia and industry. Kite Pharma of Santa Monica, Calif., has applied for FDA approval for aggressive non-Hodgkin lymphoma, and a similar Novartis application is close behind. Researchers also are exploring CAR T-cell therapys use for multiple myeloma and chronic lymphocytic leukemia, the disease that afflicted Ludwig. Theyre also tackling a far more difficult challenge using the therapy for solid tumors in the lungs or brain, for example.

The excitement among doctors and researchers is palpable. Were saving patients who three or four years ago we were at our wits end trying to keep alive, said Stephen Schuster, the Penn oncologist who is leading a Novartis lymphoma study. Both the study and a Kite trial have shown that the treatment can put about one-third of adults with advanced disease those who have exhausted all options into remission.

Yet along with the enthusiasm come pressing questions about safety, cost and the complexity of the procedure.

It involves extracting white blood cells called T cells the foot soldiers of the immune system from a patients blood, freezing and sending them to Novartiss sprawling manufacturing plant in Morris Plains, N.J. There, a crippled HIV fragment is used to genetically modify the T cells so they can find and attack the cancer. The cells then are refrozen and sent back to be infused into the patient.

Once inside the persons body, the T-cell army multiplies astronomically.

Novartis hasnt disclosed the price for its therapy, but analysts are predicting $300,000 to $600,000 for a one-time infusion. Brad Loncar, whose index fund focuses on cancer immunotherapy treatment, hopes the cost doesnt prompt a backlash. CAR-T is not the EpiPen, he said. This is truly pushing the envelope and at the cutting edge of science.

The biggest concerns, however, center on safety. The revved-up immune system becomes a potent cancer-fighting agent but also a dangerous threat to the patient. Serious side effects abound, raising concerns about broad use.

Treating patients safely is the heart of the rollout, said Stephan Grupp of the Childrens Hospital of Philadephia, who as director of its Cancer Immunotherapy Program led early pediatric studies as well as Novartiss global trial. The efficacy takes care of itself, but safety takes a lot of attention.

One of the most common side effects is called cytokine release syndrome, which causes high fever and flulike symptoms that in some cases can be so dangerous that the patient ends up in intensive care. The other major worry is neurotoxicity, which can result in temporary confusion or potentially fatal brain swelling. Juno Therapeutics, a biotech firm in Seattle, had to shut down one of its CAR T-cell programs because five patients died of brain swelling. Novartis has not seen brain swelling in its trials, company officials said.

To try to ensure patient safety, Novartis isnt planning a typical product rollout, with a drug pushed as widely and aggressively as possible. The company instead will designate 30to 35 medical centers to administer the treatment. Many of them took part in the clinical trial, and all have gotten extensive training by Grupp and others.

Grupp said he and his staff learned about the side effects of CAR T-cell therapy and what to do about them through terrifying experience that began five years ago with Emily Whitehead.

The young girl, who had relapsed twice on conventional treatments for acute lymphoblastic leukemia, was in grave condition. Grupp suggested to her parents that she become the first child to get the experimental therapy.

I said, Surely, this has been tried on kids somewhere else in the world, recalled her father, Thomas Whitehead of Philipsburg, Pa. But Steve said, Nope, some adults got it, but that was a different kind of leukemia.

After getting the therapy, Emilys fever soared, her blood pressure plummeted, and she ended up in a coma and on a ventilator for two weeks in the hospitals intensive care unit. Convinced his patient would not survive another day, a frantic Grupp got rushed lab results that suggested a surge of interleukin 6 was causing her immune system to relentlessly hammer her body. Doctors decided to give Emily an immunosuppressant drug called tocilizumab.

She was dramatically better within hours. She woke up the next day, her 7th birthday. Tests showed her cancer was gone.

The approval of CAR T-cell therapy would represent the second big immunotherapy advance in less than a decade. In 2011, the FDA cleared the first agent in a new class of drugs called checkpoint inhibitors. It has approved four more since then.

There are big differences between the two approaches. The checkpoint inhibitors are targeted at solid tumors, such as advanced melanoma, lung and bladder cancer, while CAR-T cell therapy has been aimed at blood disorders. And although checkpoint inhibitors are off the shelf, with every patient getting the same drug, the other is customized to an individual. Many immunotherapy experts think the greatest progress against cancer will occur when researchers figure out how to combine the approaches.

For the Penn team, the CAR T-cell story goes back decades, starting at the then-National Naval Medical Center in Bethesda, where June and a postdoc fellow named Bruce Levine worked on new HIV treatments. In the process, they figured out a way to turbocharge T cells to make them more powerful and plentiful.

The pair moved to Philadelphia in 1999 and dove into cancer research. Two years later, Junes wife died of ovarian cancer, something he has credited as spurring him to work even harder in the field. In the years that followed, researchers across the country, including at Memorial Sloan Kettering Cancer Center in New York and Fred Hutchinson Cancer Research Center in Seattle racked up an array of tantalizing discoveries involving T cells.

Fast-forward to 2010, when Ludwig, who lives in Bridgeton, N.J. became Penns first patient to receive CAR T-cell therapy. Two other men got the treatment not long after. One is still in remission; the other relapsed and died.

But after those three patients, the Penn researchers ran out of money for more treatments. To try to raise interest and funding, they decided to publish the results of their work. The article that appeared in the New England Journal of Medicine in August 2011 created a firestorm, June said one that brought them new resources. David Porter, a Penn oncologist working with June, was on vacation in western Maryland and had to stop at a Kohls to buy a dress shirt for the immediate TV interviews.

The pediatric trial opened the following spring with Whitehead. Six months later, Penn licensed its technology to Novartis in exchange for financial support, which included a new cell-manufacturing facility on campus.

With FDA approval seeming imminent, the researchers who were so instrumental in the therapys development and testing are almost giddy. Grupp is especially pleased that the advance will be available first to children. Usually everything is developed first for adults, he noted recently, and children are an afterthought.

San Francisco-based Vineti, a cell and gene therapy software and analytics company, has closed on Series A funding round that pulled together nearly $14 million.

Backing came from General Electric Ventures, Mayo Clinic and new investor Draper Fisher Jurvetson.

The company will use the funds to continue growing its team and to deliver cloud-based software to improve patient access. It also plans to speed its work on life-saving treatment delivery and to promote safety and FDA compliance for individualized cell therapies.

The Vineti platform integrates logistics, manufacturing and clinical data.

Physicians, medical researchers and pharmaceutical companies are working together to develop successful therapies, transitioning from a one-size-fits-all model to individualized treatments for each patient, Vineti CEO Amy DuRoss said in a statement. But, the process for administering these treatments is broken and outdated, restricting access to terminal patients and creating unnecessary risk.

DuRoss added that Vineti developed the platform to ensure treatments reach the patients who need them the most. She added that many patients who are excellent candidates dont have access to the most innovative therapies and discovery timelines are more challenging than necessary.

GE Ventures formed Vineti based on customer requests to bridge the technology gap between individualized cell therapies and production.

Modern technology solutions to address complex production and delivery processes are lacking. GE Ventures, Mayo Clinic and DFJ have invested in Vineti to rectify these problems.

Vineti is led by DuRoss, Chief Strategy Officer Heidi Hagen and CTO Razmik Abnous.

Sarepta Therapeutics has penned its second DMD gene therapy pact this year as it announces a tie-up with Frances Genethon, a nonprofit R&D org.

The research collaborationwill see the Franco-American pair jointly develop treatments for Duchenne muscular dystrophy and comes after Sareptas first FDA approval for DMD with its controversial med Exondys 51 (eteplirsen).

RELATED: FDA expert lashes out at 'worrisome' Sarepta approval in JAMA

Sarepta is looking to tap into Genethons preclinical microdystrophin gene therapy approach, which can target the majority of patients with DMD. Its current med can only treat certain patients, namely those with the mutation of the dystrophin gene amenable to exon 51 skipping, which affects about 13% of the population with DMD.

It is hoping that with new tie-ups, it could produce a gene therapy that could treat many more, if not all, patients with the disease, although this is still some years off. DMD is a rare genetic disorder characterized by progressive muscle deterioration and weakness. The disease primarily affects young boysand occurs in about one out of every 3,600 male infants worldwide.

This builds on the pacts announced at the start of the year at the JPM conference, which saw it sign a deal with the Nationwide Childrens Hospital, which also focuses on the microdystrophin gene therapy program, as well as another form of gene therapy.

An initial phase 1/2a trial for the microdystrophin gene therapy is slated to begin at the end of the year and will be done at Nationwide Childrens. It also penned an exclusive license agreement with Nationwide for their Galgt2 gene therapy program, originally developed by researcher Paul Martin. This early-stage program aims to research a potential surrogate gene therapy approach to DMD, whereby the gene therapy looks to induce genes that make proteins that can perform a similar function as dystrophin. The goal will be to produce a muscle cell that can function normally even when dystrophin is absent, Sarepta said at the time.

Under the terms of its latest collaboration, Genethon will be responsible for the early development work. Sarepta has the option to co-develop Genethons microdystrophin program, which includes exclusive U.S. commercial rights. Financial terms, as is becoming more common with these pacts, have not been disclosed.

RELATED: With Exondys 51 approved, Sarepta chief Ed Kaye to bow out

Our agreement with Genethon strengthens our ongoing commitment to patients and is aligned with our strategy of building the industrys most comprehensive franchise in DMD, said Ed Kaye, Sareptas outgoing chief. This partnership brings together our collective experience in Duchenne drug development and Genethons particular expertise in gene therapy for rare diseases. We look forward to working with Genethon given their knowledge, large infrastructure and state-of the-art manufacturing capabilities to advance next generation therapies for DMD.

Frederic Revah, CEO of Genethon, added: Microdystrophin-based gene therapy is a very promising approach with potential application to a large majority of Duchenne patients. In order to accelerate the development of a treatment, we are very pleased to partner with Sarepta Therapeutics, which has demonstrated commitment and success for innovative therapies for Duchenne muscular dystrophy. This partnership brings together the highly complementary and synergistic expertises of Sarepta and Genethon, to the benefit of the patients.

Sarepta signs another Duchenne gene therapy pact as it aims for wider treatment - FierceBiotech

British drugmaker GlaxoSmithKline made headlines last year when it won approval for its gene therapy Strimvelis in Europe. But, due to a small patient population and high price tag, the drug has only been used once. So far, despite higher levels of safety and efficacy than previous iterations, the new wave of gene therapies still face commercial hurdles.

Spark Therapeutics looks set to be the next company to take on this challenge in the U.S. The biotech is currently awaiting approval of its treatment for a rare genetic form of blindness a potential one-time cure. Yet pricing will be the most closely watched aspect of this therapy, likely serving as an early barometer of what might be sustainable for a pipeline of treatments still in development.

Gene therapy: What you need to know - BioPharma Dive

SAN FRANCISCO, Calif. Mayo Clinic Ventures has partnered with a California-based company to make cancer-fighting gene therapies available to the public.

Vineti, a pioneering cell and gene therapy software and analytics company, announced Tuesday that it had completed its initial round of funding raising $13.75 million aimed at delivering "the first cloud-based software solution to improve patient access, accelerate life-saving treatment delivery, and promote safety and regulatory compliance for individualized cell therapies."

The funding was provided by Mayo Clinic Ventures, GE Ventures, DFJ and LifeForce Capital. It's just the 15th company that Mayo Clinic Ventures has backed since it was formed, according to Andy Danielson, vice chairman of Mayo Clinic Ventures.

"One thing with Vineti that we liked is that we have a commitment to cell and gene therapies at Mayo," Danielson told TechCrunch.com. "Vineti will make the gene and cell therapy production process more efficient and as a result, less costly. It's all part of the equation of making these therapies more affordable and opening them up to a greater number of people."

The targeted cancer therapy under development by Vineti is part of a thriving field that conducted more than 800 clinical trials in 2016 while investing nearly $6 billion. It's all aimed at positively impacting the oncology field, the largest market in medicine that's expected to grow to $165 billion by 2021.

The first two cell therapies are expected to hit the market later this year.

Vineti touts its plans as one that "integrates logistics, manufacturing and clinical data to improve product performance overall and enable faster, broader access for patients."

"Physicians, medical researchers and pharmaceutical companies are working together to develop successful therapies, transitioning from a one-size-fits-all model to individualized treatments for each patient," said Amy DuRoss, CEO at Vineti. "Now, the process for creating and delivering these treatments can be as innovative as the therapies themselves. We are developing the Vineti platform to help these treatments reach the patients who need them the most, and are confident the partnership between our advances technologies and leading medical research will deliver better outcomes across the globe."

Mayo Clinic Ventures funds new cancer-fighting cell, gene therapy ... - Post-Bulletin

Doctors are reporting unprecedented success from a new cell and gene therapy for multiple myeloma, a blood cancer that's on the rise. Although it's early and the study is small 35 people every patient responded and all but two were in some level of remission within two months.

In a second study of nearly two dozen patients, everyone above a certain dose responded.

Experts at an American Society of Clinical Oncology conference in Chicago, where the results were announced Monday, say it's a first for multiple myeloma and rare for any cancer treatment to have such success.

Chemotherapy helps 10 to 30 percent of patients; immune system drugs, 35 to 40 percent at best, and some gene-targeting drugs, 70 to 80 percent, "but you don't get to 100," said Dr. Len Lichtenfeld, deputy chief medical officer of the American Cancer Society.

"These are impressive results" but time will tell if they last, he said.

ABOUT THE DISEASE

Multiple myeloma affects plasma cells, which make antibodies to fight infection. More than 30,000 cases occur each year in the United States, and more than 115,000 worldwide. It's the second fastest growing cancer for men and the third for women, rising 2 to 3 percent per year, according to the National Cancer Institute. About 60,000 to 70,000 Americans have it now.

Nine new drugs have been approved for it since 2000 but they're not cures; only about half of U.S. patients live five years after diagnosis.

With cell therapy, "I can't say we may get a cure but at least we bring hope of that possibility," said Dr. Frank Fan. He is chief scientific officer of Nanjing Legend Biotech, a Chinese company that tested the treatment with doctors at Xi'an Jiaotong University.

HOW IT WORKS

The treatment, called CAR-T therapy , involves filtering a patient's blood to remove immune system soldiers called T cells. These are altered in a lab to contain a gene that targets cancer and then given back to the patient intravenously.

Doctors call it a "living drug" a one-time treatment to permanently alter cells that multiply in the body into an army to fight cancer. It's shown promise against some leukemias and lymphomas, but this is a new type being tried for multiple myeloma, in patients whose cancer worsened despite many other treatments.

THE STUDIES

In the Chinese study, 19 of 35 patients are long enough past treatment to judge whether they are in complete remission, and 14 are. The other five had at least a partial remission, with their cancer greatly diminished. Some are more than a year past treatment with no sign of disease.

Most patients had a group of side effects common with this treatment, including fever, low blood pressure and trouble breathing. Only two cases were severe and all were treatable and temporary, doctors said.

The second study was done in the U.S. by Bluebird Bio and Celgene, using a cell treatment developed by the National Cancer Institute. It tested four different dose levels of cells in a total of 21 patients. Eighteen are long enough from treatment to judge effectiveness, and all 15 who got an adequate amount of cells had a response. Four have reached full remission so far, and some are more than a year past treatment.

WHAT EXPERTS SAY

The results are "very remarkable" not just for how many responded but how well, said Dr. Kenneth Anderson of Dana-Farber Cancer Institute in Boston.

"We need to be looking for how long these cells persist" and keep the cancer under control, he said.

Dr. Carl June, a University of Pennsylvania researcher who received the conference's top science award for his early work on CAR-T therapy, said "it's very rare" to see everyone respond to a treatment. His lab also had this happen all 22 children testing a new version of CAR-T for leukemia responded, his colleagues reported at the conference.

"The first patients we treated in 2010 haven't relapsed," June said.

Dr. Michael Sabel of the University of Michigan called the treatment "revolutionary."

"This is really the epitome of personalized medicine," extending immune therapy to more types of patients, he said.

NEXT STEPS

Legend Biotech plans to continue the study in up to 100 people in China and plans a study in the U.S. early next year. The treatment is expected to cost $200,000 to $300,000, and "who's going to pay for that is a big issue," Fan said.

"The manufacturing process is very expensive and you can't scale up. It's individualized. You cannot make a batch" as is done with a drug, he said.

Nick Leschly, Bluebird's chief executive, said the next phase of his company's study will test what seems the ideal dose in 20 more people.

A first: All respond to gene therapy in a blood cancer study - ABC News

In Brief Researchers have successfully used immunotherapy to "turn off" asthma and allergic responses in animals. This work will eventually be used to create one-shot treatments that permanently silence allergies. Erasing Asthma

Scientists from the University of Queensland have used gene therapy to turn off the immune response responsible for asthma. The team believes their technique may also be able to permanently silence severe allergy responses to common allergens such as bee venom, peanuts, and shellfish. Thus far, the research has been successful in animal trials, and if it can be replicated in human trials, it may provide a one-time treatment for asthma and allergy patients.

The technique erases the memory of the cells which cause allergic reactions using genetically modified stem cells that are resistant to allergens. We have now been able wipe the memory of these T-cells in animals with gene therapy, de-sensitizing the immune system so that it tolerates the [allergen] protein, lead researcher Ray Steptoe said in a press release. We take blood stem cells, insert a gene which regulates the allergen protein and we put that into the recipient. Those engineered cells produce new blood cells programmed to express the protein and target specific immune cells, which turn off the allergic response.

According to the Centers for Disease Control (CDC), about 1 in 12 people (25 million) in the U.S.have asthma, and these numbers are increasing annually. As of 2007, the last year for which the CDC has data, asthma cost the U.S. approximately $56 billion in costs for medical bills, lost work and school days, and early deaths. According to the World Health Organization (WHO), 235 million people worldwide have asthma, which is the most common chronic childhood disease, occurring in all countries regardless of level of development.

The researchers findings must now besubjected to further pre-clinical investigation, with the aim of replicating the results in the laboratory using human cells. The longer term goal will be a one-time gene therapy injection that would replace short-term allergy treatments, which vary in their effectiveness. We havent quite got it to the point where its as simple as getting a flu jab so we are working on making it simpler and safer so it could be used across a wide cross-section of affected individuals, Dr. Steptoe said in the press release.

A New Gene Therapy Could Hold the Key to Curing Allergies and Asthma - Futurism

A type of inherited and incurable breast cancer that tends to affect younger women could be targeted by a new therapy, researchers have found.

A small study presented at the worlds largest cancer conference found treating patients with the drug olaparib could slow cancer growth by three months and be less toxic for patients with inherited BRCA-related breast cancer.

Researchers said there was not enough data to say whether patients survived longer as a result of the treatment.

We are in our infancy, said Dr Daniel Hayes, president of the American Society of Clinical Oncology and professor of breast cancer research at the University of Michigan. This is clearly an advance; this is clearly proof of concept these can work with breast cancer.

Does it look like its going to extend life? We dont know yet, he said.

The drug is part of the developing field of precision medicine, which targets patients genes to tailor treatment.

It is a perfect example of how understanding a patients genetics and the biology of their tumor can be used to target its weaknesses and personalize treatment, said Andrew Tutt, director of the Breast Cancer Now Research Centre at The Institute of Cancer Research.

Olaparib is already available for women with BRCA-mutant advanced ovarian cancer, and is the first drug to be approved that is directed against an inherited genetic mutation. The study was the first to show olaparib can slow growth of inherited BRCA-related breast cancer. The drug is not yet approved for that use.

People with inherited mutations in the BRCA gene make up about 3% of all breast cancer patients, and tend to be younger. The median age of women in the olaparib trial was 44 years old.

BRCA genes are part of a pathway to keep cells reproducing normally. An inherited defect can fail to stop abnormal growth, thus increasing the risk of cancer. The study examined the effectiveness of olaparib against a class of BRCA-related cancers called triple negative. Olaparib is part of a class of four drugs called PARP-inhibitors that work by shutting down a pathway cancer cells use to reproduce.

The study from Memorial Sloan Kettering Cancer Center in New York randomly treated 300 women with advanced, BRCA-mutated cancer with olaparib or chemotherapy. All the participants had already received two rounds of chemotherapy.

About 60% of patients who received olaparib saw tumors shrink, compared with 29% of patients who received chemotherapy. That meant patients who received olaparib saw cancer advance in seven months, versus four months for only chemotherapy.

Researchers cautioned it is unclear whether olaparib extended life for these patients, and that more research was needed to find out which subset of patients benefit most from olaparib.

Hitachi Group subsidiary PCT Cell Therapy Services will provide clinical manufacturing services for Orchards autologous gene therapy for the treatment of adenosine deaminase deficiency.

Under terms of the deal, PCT will make clinical supplies of OTL-101, an autologous ex-vivo gene therapy for the treatment of adenosine deaminase deficiency severe combined immunodeficiency (ADA-SCID).

The Manufacturing Services Agreement (MSA) is an extension of a previous contract between the UK-based Orchard Therapeutics and its contract development and manufacturing organisation (CDMO).

We are very pleased to extend our relationship with PCT into a full GMP manufacturing services agreement for OTL-101, Orchards chief manufacturing officer Stewart Craig said in a statement.

As a world-leading CDMO for cell-based therapeutic products, this is an important step in advancing our lead program for the treatment of children afflicted with ADA-SCID.

PCTs CEO Robert Preti added the expansion will now include clinical manufacturing in support of [Orchards] ADA-SCID gene therapy is testament to our successful collaboration and our dedicated stewardship of this important program.

The clinical results are cause for hope among this patient population and we look forward to helping advance this important new therapeutic towards commercialisation.

The deal comes after Orchard announced it had contracted Dutch CMO PharmaCell to manufacture products from its gene therapy pipeline earlier this year, and seven months after the firm inked an alliance with gene and cell therapy firm Oxford BioMedica for process development services and cGMP-grade manufacture of lentiviral vectors.

Orchard did not supply further information when contacted by this publication.

Scientists have used gene therapy to 'switch off' the immune response that causes asthma, and are hopeful that the same technique could be used to target other severe allergies to peanuts, bee venom, and shellfish,keeping them at bay for life.

The research, which has so far seen success in animal trials, works byerasing the memory of the cells responsible for causing an allergic reaction, and if replicated in humans, could offer a one-off treatment for allergy patients.

"The challenge in asthma and allergies is that these immune cells, known as T-cells, develop a form of immune 'memory', and become very resistant to treatments,"says lead researcherRay Steptoefrom the University of Queensland (UQ) in Australia.

"We have now been able 'wipe' the memory of these T-cells in animals with gene therapy, de-sensitising the immune system so that it tolerates the [allergen] protein."

An allergic response is a hypersensitive immune reaction to a substance that is normally harmless. When people are exposed to their allergic trigger, it can cause anything from itchy eyes and a runny nose to - in the most extreme cases -death.

Asthma is a common allergic response of the airways affecting 2.5 million Australiansand hundreds of millions around the world. About 80 percent of people who experience asthma in Australia are susceptible to hay fever - an allergic response to rye grass pollen.

"When someone has an allergy or asthma flare-up, the symptoms they experience results from immune cells reacting to protein in the allergen," says lead researcherRay Steptoefrom the University of Queensland (UQ) in Australia.

While previous research has looked into using nanoparticle 'trojan horses' to smuggle the allergen past the immune system, and at new immunotherapy approaches, right now, the most effective treatment for people suffering from allergies is to simply avoid all known triggers.

To figure out a better way, Steptoe and his teamtook bone marrow from mice that had been genetically modified to have a resistance against asthma caused by rye grass pollen, and transplanted the bone marrow into unmodified mice.

"We take blood stem cells, insert a gene which regulates the allergen protein, and we put that into the recipient," says Steptoe.

"Those engineered cells produce new blood cells programmed to express the protein and target specific immune cells, which 'turn off' the allergic response."

Even though this study only looked at asthma, the researchers hope that the same approach could be used to provide protection against other common allergies - food and otherwise.

"Our work used an experimental asthma allergen, but this research could be applied to treat those who have severe allergies to peanuts, bee venom, shellfish and the like," Steptoe said.

But before we start throwing our puffers in the bin, the studies still have to be replicated in human trials, and that's where things get much more complicated.

"In the real world, unfortunately, it's not just usually a single allergen protein [that causes an immune response]. There might be several proteins that you might be allergic to and you'd have to target each of those proteins," Steptoe told ScienceAlert.

"We're currently doing experiments to see if we can turn off multiple response at the same time."

The research is published in JCI Insight.

Gene therapy has been used to 'switch off' asthma symptoms - ScienceAlert

By Laurie McginleyThe Washington Post

The oncologist was blunt: Stefanie Joho's colon cancer was raging out of control and there was nothing more she could do. Flanked by her parents and sister, the 23-year-old felt something wet on her shoulder. She looked up to see her father weeping.

"I felt dead inside, utterly demoralized, ready to be done," Joho remembers.

But her younger sister couldn't accept that. When the family got back to Joho's apartment in New York's Flatiron district, Jess opened her laptop and began searching frantically for clinical trials, using medical words she'd heard but not fully understood. An hour later, she came into her sister's room and showed her what she'd found.

"I'm not letting you give up," she told Stefanie. "This is not the end."

That search led to a contact at Johns Hopkins University, and a few days later, Joho got a call from a cancer geneticist co-leading a study there.

"Get down here as fast as you can!" Luis Diaz said. "We are having tremendous success with patients like you."

What followed is an illuminating tale of how one woman's intersection with experimental research helped open a new frontier in cancer treatment with approval of a drug that, for the first time, targets a genetic feature in a tumor rather than the disease's location in the body.

The breakthrough, now made official by the Food and Drug Administration, immediately could benefit some patients with certain kinds of advanced cancer that aren't responding to chemotherapy. Each should be tested for that genetic signature, scientists stress.

"These are people facing death sentences," said Hopkins geneticist Bert Vogelstein. "This treatment might keep some of them in remission for a long time."

A pivotal small trial

In August 2014, Joho stumbled into Hopkins for her first infusion of the immunotherapy drug Keytruda. She was in agony from a malignant mass in her midsection, and even with the copious amounts of OxyContin she was swallowing, she needed a new fentanyl patch on her arm every 48 hours. Yet within just days, the excruciating back pain had eased. Then an unfamiliar sensation hunger returned. She burst into tears when she realized what it was.

As months went by, her tumor shrank and ultimately disappeared. She stopped treatment this past August, free from all signs of disease.

The small trial in Baltimore was pivotal, and not only for the young marketing professional. It showed that immunotherapy could attack colon and other cancers thought to be unstoppable. The key was their tumors' genetic defect, known as mismatch repair (MMR) deficiency akin to a missing spell-check on their DNA. As the DNA copies itself, the abnormality prevents any errors from being fixed. In the cancer cells, that means huge numbers of mutations that are good targets for immunotherapy.

The treatment approach isn't a panacea, however. The glitch under scrutiny which can arise spontaneously or be inherited is found in just 4 percent of cancers overall. But bore in on a few specific types, and the scenario changes dramatically. The problem occurs in up to 20 percent of colon cancers and about 40 percent of endometrial malignancies cancer in the lining of the uterus.

In the United States, researchers estimate that initially about 15,000 people with this defect may be helped by this immunotherapy. That number is likely to rise sharply as doctors begin using it earlier on eligible patients.

Joho was among the first.

Even before Joho got sick, cancer had cast a long shadow on her family. Her mother has Lynch syndrome, a hereditary disorder that sharply raises the risk of certain cancers, and since 2003, Priscilla Joho has suffered colon cancer, uterine cancer and squamous cell carcinoma of the skin.

Stefanie's older sister, Vanessa, had already tested positive for Lynch syndrome, and Stefanie planned to get tested when she turned 25. But at 22, several months after she graduated from New York University, she began feeling unusually tired. She blamed the fatigue on her demanding job. Her primary-care physician, aware of her mother's medical history, ordered a colonoscopy.

When Joho woke up from the procedure, the gastroenterologist looked "like a ghost," she said. A subsequent CT scan revealed a very large tumor in her colon. She'd definitely inherited Lynch syndrome.

She underwent surgery in January 2013 at Philadelphia's Fox Chase Cancer Center, where her mother had been treated. The news was good: The cancer didn't appear to have spread, so she could skip chemotherapy and follow up with scans every three months.

By August of that year, though, Joho started having relentless back pain. Tests detected the invasive tumor in her abdomen. Another operation, and now she started chemo. Once again, in spring 2014, the cancer roared back. Her doctors in New York, where she now was living, switched to a more aggressive chemo regimen.

"This thing is going to kill me," Joho remembered thinking. "It was eating me alive."

Genetics meets immunology

Joho began planning to move to her parents' home in suburban Philadelphia: "I thought, 'I'm dying, and I'd like to breathe fresh air and be around the green and the trees.' "

Her younger sister wasn't ready for her to give up. Jess searched for clinical trials, typing in "immunotherapy" and other terms she'd heard the doctors use. Up popped a trial at Hopkins, where doctors were testing a drug called pembrolizumab.

"Pembro" is part of a class of new medications called checkpoint inhibitors that disable the brakes that keep the immune system from attacking tumors. In September 2014, the treatment was approved by the FDA for advanced melanoma and marketed as Keytruda. The medication made headlines in 2015 when it helped treat former President Jimmy Carter for melanoma that had spread to his brain and liver. It later was cleared for several other malignancies.

Yet researchers still don't know why immunotherapy, once hailed as a game changer, works in only a minority of patients. Figuring that out is important for clinical as well as financial reasons. Keytruda, for example, costs about $150,000 a year.

By the time Joho arrived at Hopkins, the trial had been underway for a year. While an earlier study had shown a similar immunotherapy drug to be effective for a significant proportion of patients with advanced melanoma or lung or kidney cancer, checkpoint inhibitors weren't making headway with colon cancer. A single patient out of 20 had responded in a couple of trials.

Why did some tumors shrink while others didn't? What was different about the single colon cancer patient who benefited? Drew Pardoll, director of the Bloomberg-Kimmel Institute for Cancer Immunotherapy at Hopkins, and top researcher Suzanne Topalian took the unusual step of consulting with the cancer geneticists who worked one floor up.

"This was the first date in what became the marriage of cancer genetics and cancer immunology," Pardoll said.

In a brainstorming session, the geneticists were quick to offer their theories. They suggested that the melanoma and lung cancer patients had done best because those cancers have lots of mutations, a consequence of exposure to sunlight and cigarette smoke. The mutations produce proteins recognized by the immune system as foreign and ripe for attack, and the drug boosts the system's response.

And that one colon-cancer patient? As Vogelstein recalls, "We all said in unison, 'He must have MMR deficiency!' " because such a genetic glitch would spawn even more mutations.

When the patient's tumor tissue was tested, it was indeed positive for the defect.

The researchers decided to run a small trial, led by Hopkins immunologist Dung Le and geneticist Diaz, to determine whether the defect could predict a patient's response to immunotherapy. The pharmaceutical company Merck provided its still-experimental drug pembrolizumab. Three groups of volunteers were recruited: 10 colon cancer patients whose tumors had the genetic problem; 18 colon cancer patients without it; and 7 patients with other malignancies with the defect.

The first results, published in 2015 in the New England Journal of Medicine, were striking. Four out of the 10 colon cancer patients with the defect and 5 out of the other 7 cancer patients with the abnormality responded to the drug. In the remaining group, nothing. Since then, updated numbers have reinforced that a high proportion of patients with the genetic feature benefit from the drug, often for a lengthy period. Other trials by pharmaceutical companies have shown similar results.

The Hopkins investigators found that tumors with the defect had, on average, 1,700 mutations, compared with only 70 for tumors without the problem. That confirmed the theory that high numbers of mutations make it more likely the immune system will recognize and attack cancer if it gets assistance from immunotherapy.

For Joho, now 27 and living in suburban Philadelphia, the hard lesson from the past few years is clear: The cancer field is changing so rapidly that patients can't rely on their doctors to find them the best treatments.

"Oncologists can barely keep up," she said. "My sister found a trial I was a perfect candidate for, and my doctors didn't even know it existed."

Her first several weeks on the trial were rough, and she still has some lasting side effects today joint pain in her knees, minor nausea and fatigue.

"I have had to adapt to some new limits," she acknowledged. "But I still feel better than I have in five years."

The team hopes to develop a single, injected, gene therapy treatment that could eliminate many severe allergic responses (Credit: University of Queensland)

Scientists may be one step closer to discovering a way to genetically "turn off" allergic responses with a single injection. A team of researchers at the University of Queensland has developed a new process that has successfully silenced a severe allergic response in mice, using blood stem cells engineered with a gene that can target specific immune cells.

The big challenge previous allergy researchers faced was that immune cells, known as T-cells, tended to develop a form of "memory" so that once someone developed an immune response to an allergen, it would easily recur upon future contact. The key was finding a way to erase that "memory" response to the protein in the allergen causing the immune reaction.

It's just US$19 a year.

"We take blood stem cells, insert a gene which regulates the allergen protein and we put that into the recipient," says Professor Ray Steptoe, explaining the new process developed by his team at The University of Queensland. "Those engineered cells produce new blood cells that express the protein and target specific immune cells, 'turning off' the allergic response."

The team's initial clinical investigations looked at an experimental asthma allergen, with the new process found to successfully terminate established allergic responses in sensitized laboratory mice. While the initial research has focused on a very specific asthma allergen, Professor Steptoe believes the process could be applied to many other severe allergic responses, such as peanuts, bee venom and shell fish.

The long-term goal of the research would be to develop a therapy that could cure specific allergies with a single injection, much like a vaccine.

"We haven't quite got it to the point where it's as simple as getting a flu jab," says Professor Steptoe, "so we are working on making it simpler and safer so it could be used across a wide cross-section of affected individuals."

The team is realistic about the time it will take before this discovery results in practical benefits for allergy sufferers, with at least five years more laboratory work needed before even human trials can be conducted. But this new discovery could mean that, within 10 or 15 years, asthma and other lethal allergic responses might be eliminated with a single, one-time treatment.

The findings were recent published in the journal JCI Insight.

Even as CDMO Lonza deals with FDA concerns about its cell manufacturing operationin the U.S., it has gone out and acquired a gene and cell contract manufacturer in Europe.

Lonza last week said it had acquired Netherlands-based PharmaCell for an undisclosed sum. It said the company had revenues of about 11 million last year. The company has a 15,500 cell manufacturing facility in Maastricht, The Netherlands, which can produce clinical through commercial-scale product.

Lonza said PharmaCell was primarily selected because of its expertise in autologous cell and gene therapy manufacturing, which includes experience with two licensedproducts in Europe.

"PharmaCells position in the market complements Lonzas leadership position in the allogeneic cell manufacturing market," Andreas Weiler, head of emerging technologies at Lonza said in a statement.

Autologous therapies use a patients own cells to create custom products as opposed to allogeneic therapies which can be manufactured in large batches from unrelated donor tissues such as bone marrow which can be used in off-the-shelf therapies. .

Loza said with this deal its gene therapy manufacturing network will span Europe, Asia and the U.S. It is Lonzas U.S. operation in the U.S. that recently ran into FDA concerns. Lonza had its cell therapy facility in Walkersville, Maryland,slapped with a warning letter in April after earlier halting some production of liquid media products being produced for a client.

The plant is overseen by the FDAs devices unit because its products are used for diagnostics. The letter said that retained samples were found to have Pantoea organisms that Lonza discovered after receiving two confirmed complaints for sterility failures of a of product.

A spokesperson said when the warning letter was issued that the company expects to have the problems resolved and FFM media manufacturing back online by mid-2017. The company had already begun a $7.6 million manufacturing upgrade at the facility, which is slated to be finished in 2018.

NEW YORK and CLEVELAND, May 30, 2017 (GLOBE NEWSWIRE) -- Abeona Therapeutics Inc. (Nasdaq:ABEO), a leading clinical-stage biopharmaceutical company focused on developing novel gene therapies for life-threatening rare diseases, announced today that the FDA has granted Rare Pediatric Disease Designation for Abeonas EB-101 gene therapy program for patients with dystrophic epidermolysis bullosa (DEB), including recessive dystrophic epidermolysis bullosa (RDEB), which are life-threatening genetic skin disorders characterized by skin blisters and erosions that cover the body.

These designations are granted to drugs with high promise that may address areas of unmet medical need for children with rare diseases. RDEB is a debilitating and life threatening inherited disorder with no approved treatment options available for patients today," stated Timothy J. Miller, Ph.D., President & CEO of Abeona Therapeutics Inc. Building upon the already granted FDA and EMA Orphan Drug Disease Designations for the EB-101 gene therapy program, receiving the Rare Pediatric Disease Designation is another important validation of the science and clinical approach to developing a novel gene therapy for RDEB patients.

Typically, wounds on patients with RDEB, also known as "butterfly skin" syndrome, can remain unhealed for months to years due to the inability of the skin to stay attached to the underlying dermis and can cover a large percentage of the body. In the ongoing Phase 1/2 clinical trial, EB-101 was administered to non-healing chronic wounds on each subject and assessed for wound healing at predefined time points over years. The primary endpoints of the clinical trial assess safety and evaluate wound healing after EB-101 administration compared to control untreated wounds. Secondary endpoints include expression of collagen C7 and restoration of anchoring fibrils at three and six months post-administration.

About Rare Pediatric Disease Designation: The rare pediatric disease designation indicates that the FDA may give the company a pediatric priority review voucher if the drug is approved for the pediatric indication. That voucher could then be used by the company for another drugany drugto be given a priority review. A priority review mandates that the FDA will review a BLA drug submission within six months instead of the standard 10 months. Normally, a priority review designation would only be given to a drug that is for a serious condition and has demonstrated the potential to be a significant improvement in safety and effectiveness. The priority review voucher may be used by the sponsor, sold or transferred.

EB-101 Gene Therapy Program Highlights:

About EB-101: EB-101 is an autologous, ex-vivo gene therapy in which COL7A1 is transduced into autologous keratinocytes for the treatment of Recessive Dystrophic Epidermolysis Bullosa (RDEB). RDEB is a subtype of an inherited genetic skin disorder characterized by chronic skin blistering, open and painful wounds, joint contractures, esophageal strictures, pseudosyndactyly, corneal abrasions and a shortened life span. Patients with RDEB lack functional type VII collagen owing to mutations in the gene COL7A1 that encodes for C7 and is the main component of anchoring fibrils, which stabilize the dermal-epidermal basement membrane. Patients are being enrolled in the ongoing Phase 2 portion of the Phase 1/2 clinical trial (NCT01263379). The EB-101 program has also been granted orphan drug designation by the FDA and European Medicines Agency (EMA).

About Epidermolysis Bullosa (EB): EB is a group of devastating, life-threatening genetic skin disorders that is characterized by skin blisters and erosions all over the body. The most severe form, recessive dystrophic epidermolysis bullosa (RDEB), is characterized by chronic skin blistering, open and painful wounds, joint contractures, esophageal strictures, pseudosyndactyly, corneal abrasions and a shortened life span. Patients with RDEB lack functional type VII collagen (C7) owing to mutations in the gene COL7A1 that encodes for C7 and is the main component of anchoring fibrils that attach the dermis to the epidermis. EB patients suffer through intense pain throughout their lives, with no effective treatments available to reduce the severity of their symptoms. Along with the life-threatening infectious complications associated with this disorder, many individuals often develop an aggressive form of squamous cell carcinoma (SCC).

About Abeona: Abeona Therapeutics Inc. is a clinical-stage biopharmaceutical company developing gene therapies for life-threatening rare genetic diseases. Abeona's lead programs include ABO-102 (AAV-SGSH), an adeno-associated virus (AAV) based gene therapy for Sanfilippo syndrome type A (MPS IIIA) and EB-101 (gene-corrected skin grafts) for recessive dystrophic epidermolysis bullosa (RDEB). Abeona is also developing ABO-101 (AAV-NAGLU) for Sanfilippo syndrome type B (MPS IIIB), ABO-201 (AAV-CLN3) gene therapy for juvenile Batten disease (JNCL), ABO-202 (AAV-CLN1) for treatment of infantile Batten disease (INCL), EB-201 for epidermolysis bullosa (EB), ABO-301 (AAV-FANCC) for Fanconi anemia (FA) disorder and ABO-302 using a novel CRISPR/Cas9-based gene editing approach to gene therapy for rare blood diseases. In addition, Abeona has a plasma-based protein therapy pipeline, including SDF Alpha (alpha-1 protease inhibitor) for inherited COPD, using its proprietary SDF (Salt Diafiltration) ethanol-free process.

The gene may be inserted through Germ line gene therapy is still an emerging technique that needs to be perfected before being tested on humans. Germ line therapy is also, a more challenging than the more common somatic cell gene therapy. However, germ line therapy raises concerns regarding ethics and morality. The two main methods of performing germ-line gene therapy would be:

(Citation 17) (Citation 17) 2) Somatic Cell Gene Therapy: The most studied gene therapy, somatic cell therapy uses the insertion of a normal gene into the DNA of somatic cells in order to compensate for the non-functioning defective gene. Which can be done in a number of ways including:

(Citation 17) Virus Vectors: Both Somatic and Germ line gene therapy, need a way to insert DNA into a cell therefore carrier molecule called a vector must be used to deliver the therapeutic gene to the patient's target cells. The most efficient and effective vectors to date are viruses. Viruses can be genetically altered to carry normal human DNA, then passing on the healthy genes to human cells. Much like a chauffeur who picks up and delivers people to certain locations. Some examples of viruses that are used as vectors are: Retroviruses, Retroviruses, Adeno-associated viruses, and Herpes simplex viruses.

3) Chimeraplasty : This technique is the least known of all three methods. It is a non- viral method that is still being researched for its potential in gene therapy. Chimeraplasty is done by changing DNA sequences in a person's genome using a synthetic strand composed of RNA and DNA. This strand of RNA and DNA is known as a chimeraplast. The chimeraplast enters a cell and attaches itself to the target gene. The DNA of the chimeraplast and the cell complement each other except in the middle of the strand, where the chimeraplast's sequence is different from that of the cell. The DNA repair enzymes then replace the cells DNA with that of the chimeraplast. This leaves the chimeraplast's new sequence in the cell's DNA and the replaced DNA sequence then decays.

MOUNTAIN VIEW, CA--(Marketwired - May 15, 2017) - SENS Research Foundation (SRF) has launched a new research program focused on somatic gene therapy in collaboration with the Buck Institute for Research on Aging. Brian Kennedy, PhD, a leading expert on the biology of aging, will be running the project in his lab at the Buck.

Many potential treatments of age-related diseases require the addition of new genes to the genome of cells in the body, a technology known as somatic gene therapy. The technology has been hampered, up until now, by the inability to control where the gene is inserted. That lack of control resulted in a significant risk of insertion in a location that encourages the cell to become malignant.

SRF has devised a new method for inserting genes into a pre-defined location. In this program, this will be done as a two-step process, in which first CRISPR is used to create a "landing pad" for the gene, and then the gene is inserted using an enzyme that only recognizes the landing pad. SRF has created "maximally modifiable mice" that already have the landing pad, and this project will evaluate how well the insertion step works in different tissues.

"Somatic gene therapy has been a goal of medicine for decades. Being able to add new healthy genes will enable us to address treatments of such age-related diseases as atherosclerosis and macular degeneration. Our collaboration with SRF will substantially move us toward finding effective treatments to genetically based age-related diseases," said Dr. Kennedy.

"Partnering with Brian Kennedy and the Buck enables SRF to continue towards our goal of achieving human clinical trials on rejuvenation biotechnologies in the next five years. Brian's leadership in moving this technology into mammals is a huge step forward," said Dr. Aubrey de Grey, CSO, SENS Research Foundation.

This research has been made possible through the generous support of the Forever Healthy Foundation and its founder Michael Greve, as well as the support of our other donors. The Forever Healthy Foundation is a private nonprofit initiative whose mission is to enable people to vastly extend their healthy lifespans and be part of the first generation to cure aging. In order to accelerate the development of therapies to bring aging under full medical control, the Forever Healthy Foundation directly supports cutting-edge research aimed at the molecular and cellular repair of damage caused by the aging process.

Isarna Therapeutics showed off positive Phase I data for its lead compound ISTH0036 in patients with Glaucoma at the ARVO meeting last week.

Isarna Therapeutics from Munich is developing TGF- specific antisense RNA therapeuticsto treat ophthalmic and fibrotic diseases and cancer.Now the company hascleared its first Phase I trial for its lead candidate ISTH0036 in patients with advancedglaucoma. Additionally, the company is set to expand into further indications, with preclinical data demonstrating the drugs potential in models of age-related macular degeneration (AMD) and diabetic macular edema (DME).

We are now moving towards Phase II development in advanced glaucoma but also other TGF-2 associated diseases such as wet Age-related Macular Degeneration (AMD) and other TGF2-associated diseases such as Diabetic Macular Edema (DME), well supported by the recent preclinical data we could gather for these diseases,commented Eugen Leo, Head of Clinical Development at Isarna.

In glaucoma, the second leading cause of vision impairment, thebuild-up of fluid in the eye leads to an increased intraocular pressure (IOP) that eventually damages the optic nerve.Scientific data indicates that disease progression is associated with elevated levels of TGF-2 that result in alterations of the trabecular network and potentially direct toxic effects on the optic nerve.

ISTH0036 is an antisense oligonucleotide targeting the mRNA of TGF-2, thereby inhibiting its transcription. The new Phase I study revealed that the gene therapy wassafe and well-tolerated in all patients and even demonstrated preliminary evidence for clinical efficacy regarding postoperative control of intraocular pressure (IOP).

Isarnas antisense RNA approach is very different from currently approved treatments for glaucoma, which includebeta blockers and alpha agonists thatboth work by reducing the production of intraocular fluid. However, French Eyevensys, which we interviewed last week at BioTrinity,is going for a similar strategy. The company just started clinical development of its lead compoundEYS606,a plasmid which encodes for an anti-TNF drug to treat patients with non-infectious uveitis. Similar to Isarna, the company is planning to expand its indications to address a number ophthalmic conditions such as AMD and DME.

Although the AMD market is expected to reach a whopping$8Bby 2020, the competition within this field is fierce, with big players like Regeneron and Roche dominating both AMD and DME markets with their effective VEGF-inhibitors Eyelea and Lucentis, respectively.

German Biotech Clears Phase I with New Gene Therapy for Glaucoma - Labiotech.eu (blog)

After deals and acquisitions with Spark Therapeutics and Bamboo, Pfizer is once again looking to bolster its rare and gene therapy pipeline as it outlines a new drug pact with Sangamo.

The collaborationlicense agreement focuses on the development and eventual sale of the biotechs gene therapy programs for hemophilia A, including SB-525, one of Sangamos four lead product candidates.

This early candidate is slated to enter the clinic this quarter, centering on testing safety as well as blood levels of Factor VIII protein, and other efficacy endpoints.

Sangamo gets $70 million upfront from the Big Pharma, and could gain $475 million in biobucks and sales royalties on any medications from the collaborationthat gain approval.

Under the deal, Sangamo will take the lead on the SB-525 phase 1/2 test as well as unspecified manufacturing activities.

Pfizer, meanwhile, will be operationally and financially responsible for subsequent research, development, manufacturing and commercialization activities for the therapy, as well as any additional products, if any.

Sangamo will also work with Pfizer on manufacturing and technical ops using viral delivery vectors.

SB-525 works as a AAV vector carrying a Factor VIII gene construct driven by a synthetic, liver-specific promoter. The FDA has already cleared the start of human trials for SB-525, and given it an orphan drug tag.

The deal has proved powerful for Sangamo, with its shares jumping 44% after hours on the news last night.

This marks another step into the new world of gene therapies for Pfizer, coming less than a year after its $700 million buy of Bamboo Therapeutics, adding advanced recombinant adeno-associated virus (rAAV)-based gene therapies to its pipeline.

It also has a long-standing deal with Spark Therapeutics, in hemophilia, penned in 2014. Back in January, Pfizer in fact paid a $15 million milestone bonus to Spark for hitting its marks in the ongoing hemophilia B phase 1/2 trial FDA breakthrough-tagged SPK-9001.

Pfizer also has a series of preclinical gene therapies, including a neuromuscular candidate for Duchenne muscular dystrophy (DMD), as well as preclinical candidates to treat Friedreichs ataxia and Canavan disease, and a phase I candidate for giant axonal neuropathy.

Pfizer also gained an operating gene therapy manufacturing facility that Bamboo bought from the University of North Carolina last year.

The pharma also has several academic research agreements, including one with Kings College London to develop a series of rAAV gene therapy vectors and another with the University of Iowa Research Foundation to develop a potential gene therapy for cystic fibrosis.

And its partnered with Emeryville, CA-based Molecular Therapeutics (4DMT) to discover and develop targeted next-generation rAAV vectors for cardiac disease; it made an investment in the company a few years back.

Once seen as the next big thing in research, gene therapies have however come under pressure in recent months about just how viable they are on the market. After struggling for years to make a commercial success out of Glybera, the worlds first approved gene therapy, uniQure recently called it quits on the treatment.

The drugmaker said it wouldnt bother asking European authorities to renew the $1-million-plus gene therapys marketing authorization when it expires in October, and comes after it abandoned plans to gain an approval in the U.S. Reports from MIT Technology Review suggest only one patient ever used the med.

GlaxoSmithKline has also been struggling in Europe with its bubble boy syndrome gene therapy Strimvelis. Mindful of Glyberas cost, GSK put its price tag at half that of Glybera, at $665,000, and also offered a money-back guarantee.

Its been approved in Europe for nearly a year, but it only treated its first patient this month, according to Business Insider.

Treatment is tough as the drug is not so much manufactured as it is created for each individual patient, with a site in Italy currently the only approved site in the world for this type of manufacture, and thus the only place where patients can be treated. Only around 15 patients in Europe are believed to have the condition.

Other biotechs are however working on the manufacturing side in order to try and make these therapies more available for patients, and thus open up their viability.

There are already a number of medications on the market for hemophilia, such as from Biogen spin-off Bioverativ and Sobi, with gene therapy predicted by some also working in the space, including uniQure and BioMarin, to be the next class for treating the blood disorder.

But speaking to FierceBiotech at the start of the year, Bioverativs new chief and former Biogen exec John Cox told me that while they are to working on gene therapy approaches to hemophilia, there are reasons to be cautious: There are of course question marks over gene therapy: The obvious one is safety, because of the history here, and this is a risk-averse population, for good reason, and the other question is naturally over efficacy, and how long does it last, as well as manufacturing, scale and so on.

Were all hoping for a cure, and of course were doing work on gene therapy now, but I dont think people are looking at these now as a permanent cure; the questions are over durability, rather than cure.

He said that investors and even doctors talk a lot about gene therapy in the hemophilia space, but that if you talk to hemophilia A patients about what they really want, being able to dose, once a week [which is the target with its candidate, or even just less frequently, is what they want.

Pfizer doubles down on gene therapy pipeline with $70M Sangamo buy-in - FierceBiotech

Christopher Reinhard will tell you there is nothing unusual about the 20-plus years hes spent getting an experimental heart therapy to late-stage clinical trials.

Very rarely will you get a short story on development of a drug, said Reinhard (above), who is a principal investor and the CEO of San Diego-based Angionetics. Two decades is about what you would expect for a new drug-making method, Reinhard said.

That may be true, but it doesnt begin to convey the tortuous path that Reinhard has followed to get Angionetics where it is today. The biotech is starting a phase 3 trial in the next few months that seeks to enroll some 320 patients with myocardial ischemiawhen clogged coronary arteries reduce the flow of oxygen-rich blood to the heart.

To treat the disease, Angionetics isnt testing some new type of cholesterol-lowering drug, or a stent to help open clogged arteries.

Rather, its attempting a risky and less-proven methodgene therapy, in which new genetic instructions are transported into the body to help produce a specific protein. Gene therapies have been in development for decades, but are only now starting to come of age thanks to a variety of technological advances. Two therapies are approved in Europe, from UniQure (NASDAQ: QURE) and GlaxoSmithKline, both for ultra rare immune and metabolic diseases. Spark Therapeutics (NASDAQ: ONCE) this year is expected to file the first ever U.S. approval application for a gene therapy, a treatment for a form of childhood blindness.

Angionetics gene therapy, Ad5FGF-4 (Generx), is intended to stimulate the growth of new blood vessels in the heart. A catheter inserted through the groin delivers the genescarried within modified virusesinto heart cells, where they are supposed to produce a protein, fibroblast growth factor-4, that helps grow new blood vessels.

The hope is to ease chest pain and relieve the effects of clogged coronary arteries by stimulating the growth of new blood vessels in areas in the heart where there is insufficient blood flow. Were just taking the heart and trying to enhance its ability to grow more blood vessels, Reinhard said.

While gene therapies are more advanced than ever, and several experimental treatments aimed at heart disease and heart failure are being tested, none have yet succeeded. A heart failure gene therapy from San Diegos Celladon, for instance, failed in 2015.

Still, the potential prize is substantial. Of the estimated 16.5 million Americans with coronary heart disease, Angionetics Reinhard said about half experience heart-related chest pain.

The current standard of care offers two principal methods of treatment. The first course of therapy is usually to prescribe drugs like nitrates that temporarily dilates blood vessels to Next Page
