DUBLIN--(BUSINESS WIRE)--The "Global Regenerative Medicines Market 2020-2030: Focus on Products, Applications, 17 Countries' Data and Competitive Landscape" report has been added to ResearchAndMarkets.com's offering.

The global regenerative medicines market is projected to reach $87.03 billion by 2030 and set to witness a CAGR of 13.99% from 2020 and 2030.

The market is driven by certain factors, including increasing consolidation among healthcare juggernauts, rising number of clinical trials for regenerative therapies, a favorable regulatory environment to accelerate approvals and market entry, and rising awareness for stem cell therapeutics, that are fueling the growth of the global regenerative medicines market.

Regenerative medicine is challenging the current healthcare practices by targeting the treatment of the root causes of disease and disorders, transforming it into an incredibly exciting space. However, these advancements have not come without significant challenges and uncertainties, which will also further need to be overcome to realize the full potential of regenerative medicine.

Cell and gene therapies, under the regenerative umbrella, are slowly and steadily becoming a healthcare standard, particularly in developed regions such as the U.S. and Europe, where already established markets for tissue engineering and stem cell have largely been responsible for driving the global regenerative medicine phenomenon. Cell and gene therapies, though advancing at a rapid pace, have primarily been targeted for hematological malignancies.

However, the same potential has not been replicated in solid tumor applications, consequently creating demand for cell therapies focusing on solid tumors. As a result, the industry is now moving toward the research and subsequent clinical translation of next-generation therapies, led by natural killer (NK) cells, which offer a viable option for solid tumors as well. Such trends are consistently propelling the industry toward realizing the true potential of precision medicine.

Within the research report, the market is segmented on the basis of products, applications, and region. Each of these segments covers the snapshot of the market over the projected years, the inclination of the market revenue, underlying patterns, and trends by using analytics on the primary and secondary data obtained.

Competitive Landscape

The global regenerative medicines market is currently witnessing several developments, primarily aimed toward bringing new products to support clinicians for the treatment of life-threatening disorders. Major manufacturers of regenerative medicine products are actively involved in undertaking significant business strategies in order to translate success in research and development into the commercial clinical setting.

Novartis, Gates Foundation pursue a simpler gene therapy for sickle cell – STAT

Friday, February 19th, 2021

Novartis and the Bill and Melinda Gates Foundation are joining forces to discover and develop a gene therapy to cure sickle cell disease with a one-step, one-time treatment that is affordable and simple enough to treat patients anywhere in the world, especially in sub-Saharan Africa where resources may be scarce but disease prevalence is high.

The three-year collaboration, announced Wednesday, has initial funding of $7.28 million.

Current gene therapy approaches being developed for sickle cell disease are complex, enormously expensive, and bespoke, crafting treatments for individual patients one at a time. The collaboration aims to instead create an off-the-shelf treatment that bypasses many of the steps of current approaches, in which cells are removed and processed outside the body before being returned to patients.

advertisement

Sickle cells cause is understood. The people it affects are known. But its cure has been elusive, Jay Bradner, president of the Novartis Institutes for BioMedical Research, told STAT.

We understand perfectly the disease pathway and the patient, but we dont know what it would take to have a single-administration, in vivo gene therapy for sickle cell disease that you could deploy in a low-resource setting with the requisite safety and data to support its use, he said. Im a hematologist and can assure you that in my experience in the clinic, it was extremely frustrating to understand a disease so perfectly but have so little to offer.

advertisement

Sickle cell disease is a life-threatening inherited blood disorder that affects millions around the world, with about 80% of affected people in sub-Saharan Africa and more than 100,000 in the U.S. The mutation that causes the disease emerged in Africa, where it protects against malaria. While most patients with sickle cell share African ancestry, those with ancestry from South America, Central America, and India, as well as Italy and Turkey, can also have the hereditary disease.

The genetic mutation does its damage by changing the structure of hemoglobin, hampering the ability of red blood cells to carry oxygen and damaging blood vessels when the misshapen cells get stuck and block blood flow. Patients frequently suffer painful crises that can be fatal if not promptly treated with fluids, medication, and oxygen. Longer term, organs starved of oxygen eventually give out. In the U.S., that pain and suffering is amplified when systemic and individual instances of racism deny Black people the care they need.

Delivering gene therapy for other diseases has been costly and difficult even in the best financed, most sophisticated medical settings. Challenges include removing patients cells so they can be altered in a lab, manufacturing the new cells in high volume, reinfusing them, and managing sometimes severe responses to the corrected cells. Patients also are given chemotherapy to clear space in their bone marrow for the new cells.

Ideally, many of those steps could be skipped if there were an off-the-shelf gene therapy. That means, among other challenges, inventing a way to eliminate the step where each patients cells are manipulated outside the body and given back the in vivo part of the plan to correct the genetic mutation.

Thats not the only obstacle. For a sickle cell therapy to be successful, Bradner said, it must be delivered only to its targets, which are blood stem cells. The genetic material carrying corrected DNA must be safely transferred so it does not become randomly inserted into the genome and create the risk of cancer, a possibility that halted a Bluebird Bio clinical trial on Tuesday. The payload itself mustnt cause such problems as the cytokine storm of immune overreaction. And the intended response has to be both durable and corrective.

In a way, the gene delivery is the easy part because we know that expressing a normal hemoglobin, correcting the mutated hemoglobin, or reengineering the switches that once turned off normal fetal hemoglobin to turn it back on, all can work, Bradner said. The payload is less a concern to me than the safe, specific, and durable delivery of that payload.

For each of these four challenges delivery, gene transfer, tolerability, durability there could be a bespoke technical solution, Bradner said. The goal is to create an ensemble form of gene therapy.

Novartis has an existing sickle-cell project using CRISPR with the genome-editing company Intellia, now in early human trials, whose lessons may inform this new project. CRISPR may not be the method used; all choices are still on the table, Bradner said.

Vertex Pharmaceuticals has seen encouraging early signs with its candidate therapy developed with CRISPR Therapeutics. Other companies, including Beam Therapeutics, have also embarked on gene therapy development.

The Novartis-Gates collaboration is different in its ambition to create a cure that does not rely on an expensive, complicated framework. Novartis has worked with the Gates Foundation on making malaria treatment accessible in Africa. And in October 2019, the Gates Foundation and the National Institutes of Health said together they would invest at least $200 million over the next four years to develop gene-based cures for sickle cell disease and HIV that would be affordable and available in the resource-poor countries hit hardest by the two diseases, particularly in Africa.

Gene therapies might help end the threat of diseases like sickle cell, but only if we can make them far more affordable and practical for low-resource settings, Trevor Mundel, president of global health at the Gates Foundation, said in a statement about the Novartis collaboration. Its about treating the needs of people in lower-income countries as a driver of scientific and medical progress, not an afterthought.

Asked which is the harder problem to solve: one-time, in vivo gene therapy, or making it accessible around the world, David Williams, chief of hematology/oncology at Boston Childrens Hospital, said: Both are going to be difficult to solve. The first will likely occur before the therapy is practically accessible to the large number of patients suffering the disease around the world.

Williams is also working with the Gates Foundation, as well as the Koch Institute for Integrative Cancer Research at MIT, Dana-Farber Cancer Institute, and Massachusetts General Hospital, on another approach in which a single injection of a reagent changes the DNA of blood stem cells. But there are obstacles to overcome there, too, that may be solved by advances in both the technology to modify genes and the biological understanding of blood cells.

Bradner expects further funding to come to reach patients around the world, once the science progresses more.

There is no plug-and-play solution for this project in the way that mRNA vaccines were perfectly set up for SARS-CoV-2. We have no such technology to immediately redeploy here, he said. Were going to have to reimagine what it means to be a gene therapy for this project.

Charles River Laboratories will acquire Cognate BioServices, a cell and gene therapy contract development and manufacturing organization, in an $875 million cash deal that will significantly expand the companys capabilities in the high-growth cell and gene therapy sector.

In addition to expanding Charles Rivers capabilities in the cell and gene therapy space, the company said the acquisition of Memphis, Tenn.-based Cognate will also establish a comprehensive solution from discovery and non-clinical development through CGMP manufacturing in advanced drug modalities. Cognate has a global presence with more than 500 employees. In January, Cognate announced plans to significantly expand cell and gene therapy manufacturing capacity, laboratory space, warehousing capabilities, and increase office support at its facilities inthe United StatesandEurope.

The company has extensive experience producing various cell types and technologies used in cellular immunotherapy and immuno-oncology, regenerative medicine and advanced cell therapy. Its primary area of expertise is in CGMP cell therapy manufacturing, which processes a variety of cellular products and other starting materials to develop and produce allogeneic (donor-derived) and autologous (patient-derived) cell therapies. Cognate also produces plasmid DNA, which is a foundational tool used in the development of gene-modified cell therapies and gene therapies, as well as other CDMO inputs, Charles River said.

James C. Foster, president and chief executive officer of Charles River Labs, said Cognate provides a synergistic fit for Charles River. He said bringing Cognate under the companys umbrella presents a unique opportunity to expand the companys capabilities and also enhance its offerings to clients in emerging areas of scientific innovation.

Additionally, Charles River said the addition of Cognate will complement its existing Biologics Testing Solutions business. Cognates capabilities will enable clients to seamlessly conduct analytical testing, process development, and manufacturing for advanced modalities with the same scientific partner, enabling them to achieve their goal of driving greater efficiency, the company said.

The addition of Cognate is also expected to provide a significant financial boost to Charles River. Cognate is expected to generate annual revenue of approximately $140 million in 2021, and is expected to grow at least 25% annually over the next five years, the company said.

This acquisition will be an exceptional strategic fit, adding to our comprehensive suite of early-stage research and manufacturing support solutions and enabling us to achieve our goal of establishing a single scientific partner to provide biopharmaceutical clients with an integrated solution to help accelerate their cell and gene therapy programs from discovery and non-clinical development through commercialization, Foster said in a statement. Because of the synergistic fit with Charles River, the market growth potential, and the emerging role of advanced drug modalities as treatments for oncology and rare disease, we believe Cognate will meaningfully enhance our long-term revenue and earnings growth potential.

The acquisition is expected to move quickly. Charles River anticipates the closing of the deal by the end of the first quarter of 2021. Based on the anticipated completion of the acquisition by the end of the first quarter, Cognate is expected to add approximately $110 million to Charles Rivers 2021 consolidated revenue for the partial year.

Novartis and Gates Foundation Team Up To Deliver Affordable Sickle Cell Gene Therapy – BioSpace

Friday, February 19th, 2021

Taljat David/Shutterstock

Novartis and the Bill & Melinda Gates Foundation have partnered on a single-dose, in vivo gene therapy for sickle cell disease (SCD). The Foundation will offer funding for development of the therapy.

Existing gene therapy approaches to sickle cell disease are difficult to deliver at scale and there are obstacles to reaching the vast majority of those affected by this debilitating disease, said Jay Bradner, a hematologist and president of the Novartis Institutes for BioMedical Research (NIBR). This is a challenge that calls for collective action, and we are thrilled to have the support of the Bill & Melinda Gates Foundation in addressing this global unmet medical need.

The announcement comes only a day after bluebird bio announced that it has placed its Phase I/II and Phase III trial of LentiGlobin gene therapy for sickle cell disease (SCD) on temporary suspension. The cause is a Suspected Unexpected Serious Adverse Reaction (SUSAR) of acute myeloid leukemia (AML).

HGB-206 is the companys ongoing Phase I/II trial of LentiGlobin for SCD. It includes three cohorts, A, B and C. In Group C, a refined manufacturing process designed to increase vector copy number was used.

Group C also received LentiGlobin for SCD manufactured from hematopoietic (blood) stem cells (HSCs) collected from peripheral blood after mobilization with plerixafor, instead of by way of bone marrow harvest, which was the method used in Groups A and B.

HGB-210 is their ongoing Phase III single-arm open-label trial. It is evaluating efficacy and safety of LentiGlobin for SCD in patients between two years and 50 years of age with sickle cell disease.

Which underlines that even though gene therapy is making headway, it is still a cutting-edge technology.

SCD is a hereditary blood disease that affects millions of people globally, with more than 300,000 born with it each year. It primarily affects people of African descent, and sub-Saharan Africa bears about 80% of the disease burden. It affects the structure of red blood cells, causing a distinct sickle shape, which decreases the ability of red blood cells to transport oxygen efficiently.

Gene therapies might help end the threat of diseases like sickle cell, but only if we can make them far more affordable and practical for low-resource settings, said Trevor Mundel, president of Global Health at the Gates Foundation. Whats exciting about this project is that it brings ambitious science to bear on that challenge. Its about treating the needs of people in lower-income countries as a driver of scientific and medical progress, not an afterthought. It also holds the promise of applying lessons learned to help develop potentially curative options for other debilitating diseases affecting low-income populations, such as HIV.

Novartis also announced today that the U.S. Food and Drug Administration (FDA) approved the expanded indication for Entresto (sacubitril/valsartan) to decrease the risk of cardiovascular death and hospitalization for heart failure in adults with chronic heart failure. The biggest benefit was for patients with left ventricular ejection fraction (LVEF) below normal.

The expansion was based on data in the PARAGON-HF Phase III trial.

This approval is a significant advancement, providing a treatment to many patients who were not eligible for treatment before because their ejection fraction was above the region we normally considered reduced, said Scott Solomon, professor of Medicine at Harvard Medical School and Brigham and Womens Hospital, and PARAGON-HF Executive Committee co-chair. We can now offer a treatment to a wider range of patients who have an LVEF below normal.

Kolon Life executives acquitted of falsifying data of gene therapy drug – The Korea Herald

Friday, February 19th, 2021

Two Kolon Life Science executives were acquitted Friday of involvement in the company's allegedly fraudulent report on a key ingredient in its gene therapy drug.

The Seoul Central District Court handed down the ruling to the drugmaker's two executives, surnamed Cho and Kim, who were indicted on charges that included fraud related to the company's suspected illegalities in the development and sales of Invossa, a cell and gene therapy for osteoarthritis.

But the court separately ordered Cho, a senior director at the company's clinical development team, to pay a fine of 5 million won ($4,500) for bribing an official at the Ministry of Food and Drug Safety in seeking favors in the company's drug development process.

They were suspected of having been involved in submitting fraudulent documents on purpose to the ministry to get approval for Invossa.

While acknowledging that the company submitted some false data, the court said the ministry seemed to have failed to perform due diligence in verifying the submitted documents.

The court also found them not guilty of fraud and other charges for having received a state subsidy of 8.2 billion won based on allegedly fraudulent documents.

Kolon Life Science, a unit of Kolon Group, initially received the approval for Invossa in 2017. But it was revoked in May 2019 after it was revealed that a key material used in Invossa came from a kidney cell, instead of from cartilage as stated in the document submitted for approval.

The company acknowledged that a substance in the joint pain treatment drug had been mislabeled, but claimed no one has suffered from any medical complications from the drug use.

Later in the day, however, the Seoul Administrative Court ruled against the drugmaker, dismissing its plea to reinstate the license for Invossa.

Having submitted false data was "a grave fault as drugs can have a significant effect on people's lives and health," the court said, even though it was hard to confirm with the evidence presented that the company intentionally committed any wrongdoing.

"There is no illegality with the ministry's decision to revoke the license since it did not seem to be aware of data that could raise suspicions about the drug's safety," the court ruled. (Yonhap)

Cancer and Gene Therapy | In the Pipeline – Science Magazine

Friday, February 19th, 2021

Theres news today that Bluebird has suspended its gene therapy work on sickle cell disease because of two cases of cancer in its treatment population. Another had been reported in 2018, so that takes us to two cases of myelodysplastic syndrome and one case of myeloid leukemia (which can be a sequel of MDS in some cases). This isnt good. Youll note that all of these are diseases of the bone marrow, and the marrow is where a good deal of the action in this sort of gene therapy takes place.

There are several companies working in this space, and its no coincidence. Sickle cell anemia is the absolute prototype of a genetically linked disorder, famously first identified in 1949 by Linus Pauling and co-workers. That paper termed it a molecular disease, and Pauling certainly deserves the credit he gets as a founder of molecular biology. Both sickle cell and the conceptually related beta-thalassemias are defects in the production of hemoglobin, and it has been obvious for decades that if you could somehow yank the defective gene out of the patients and replace it with a normal sequence that they simply wouldnt have these conditions any more.

There are by now plenty of other genetic disorders that fall into the same category, but these blood-cell based ones have a unique feature that has put them into the forefront of actual attempts at gene therapy. In these cases, all the relevant cells come from the same tissue, the bone marrow. And we actually have ways to kill that off and to swap in new tissue of our choosing: a bone marrow transplant. It is a tough procedure to go through, for sure, but not as tough as living a life of acute sickle cell attacks (or being killed off early by rampaging leukemia, to pick another application).

Contrast that with so many other gene-linked disorders take Huntingtons, for example. We know the gene for that one, and the protein it codes for, and it is equally obvious that if you could magically yank out that gene from a patient and insert the normal one for the Htt protein that they would no longer have the disease. But there is no analogous procedure for killing off the basal ganglia of the brain and replacing it with new neuronal tissue. Not quite. No, bone marrow based disorders are a unique opportunity, and thats why so much effort has gone into this area.

Its a similar situation to the way that therapeutic RNAs have been aimed at liver disorders. In that case, youre not wiping out the old cell population but rather trying to overwhelm it in situ, and the liver is chosen because we dont really know how to make i.v. dosed RNA species accumulate anywhere else. So we make do with what we have and turn the Liver Problem into the Liver Advantage. If we ever get to the point of treating Huntingtons at a genetic level, its surely going to be via a similar rework-things-in-situ method as well, but figuring out to do that in only the desired regions of the brain without causing trouble elsewhere is quite a challenge youve lost the Liver Advantage.

Now, Bluebird. They have been using a lentivirus vector to rewrite the bone marrow transplant tissue, and theres a solid reason for that. Lentiviruses (of which HIV is the most famous/infamous example) insert their genetic payloads into the host cells DNA. Its their key step, and they can do it even on non-dividing cells. Now, when a person hears viral vector these days, the thought is immediately of vaccines, and that takes us to the worry that the vaccines aimed at the COVID-19 pandemic will do things to our DNA. But were not using lentiviruses for the viral-vector vaccines were using adenoviruses, because those explicitly do not work by inserting genes into host DNA. Thats also a feature of the mRNA vaccines: messenger RNA is not incorporated into our DNA. Those two species are constantly working in close proximity in living cells and theres a huge pile of optimized protein machinery to keep them from getting crossed in that fashion. Nor does a messenger RNA sequence get turned back into DNA and inserted that way. Every cell has hundreds of thousands of mRNA molecules in it at any given time, and things would come to a catastrophic halt if these started getting reversed back into DNA sequences. (Our cells do have some RNA-to-DNA machinery in them, but it doesnt work like that).

But for gene therapy, the opposite considerations apply you most certainly want to insert new genes into human DNA, and you want it done quickly, efficiently, and right where you tell it to go. That last part is always the worry with any gene-insertion technique, be it some variety of CRISPR, zinc-finger nucleases, lentivirus vectors or what have you. This is one of the main reasons the human-editing experiment in China was so amazingly irresponsible, because our control over such things in a human embryo is just not acceptable yet. Not even close.

In fact, its tricky enough just in the stem cells pulled out of bone marrow. Thats one possibility for what Bluebird is seeing that when they treated the patients extracted cells with their lentivirus vector, that some of the hemoglobin genetic data got mishandled and plopped into the wrong stretch of DNA, demolishing some other important genes function in the process. You can be sure that theyre sequencing the abnormal blood cells from these patients now to see if this shows up. The MDS patient from 2018 turned out not to have this problem, so its possible that these two just reported dont, either. So whats the problem, if not that?

Well, as mentioned, bone marrow transplantation is a grueling process no matter what. The process of (either mostly or completely) wiping out a persons bone marrow stem cells involves severe treatments mixing chemotherapy with radiation, and one of the compounds used (and used by Bluebird) is called busulfan. The organic chemists in the crowd will find that one interesting: its the bis-mesylate of 1,4-butanediol, nothing more and nothing less, and if the thought of taking a reactive small molecule like that intravenously gives you the shivers, well, welcome to chemotherapy and get ready for some stuff thats even worse. The thing is, busulfan itself is a Class I carcinogen (as one would expect from its structure). Many older chemotherapy agents are. They are destructive to cells, and the only way you would take any of them is if you have a population of cells that you actually want to see destroyed, and you are willing to take your chances that you can bear up under the collateral damage of doing that. So its certainly possible that the leukemia seen in Bluebirds patients is at least partly driven by the bone marrow transplantation procedure rather than the gene alteration part. In case youre wondering, this could well be happening with some bone marrow transplant patients who undergo this whole procedure to treat leukemia itself, in which case it lands silently in the relapsed category. No, you only do bone marrow transplants when theres no alternative.

As that first link in todays post (Adam Feuerstein at STAT) mentions, though, theres ongoing research to make that part of the process less risky. Survival rates for bone marrow transplants in general have steadily improved over the years, and everyone knows that one of the rough parts is the pre-treatment. But that problem might or might not get solved in time to help out Bluebird (or to quell the worries that other gene-therapy outfits might have who are also targeting that hematopoietic tissue). If indeed its the problem in the first place. . .

Sensorion and Institut Pasteur announce new gene therapy collaboration – BioPharma-Reporter.com

Friday, February 19th, 2021

The new gene therapy target,GJB2 coding for the Connexin 26 protein, has been added to Sensorions development portfolio: with the target the third candidate to emerge from the R&D collaboration with Institut Pasteur. It represents the largest gene therapy opportunity for the French biotech to date.

The GJB2 program will focus on major new markets with an estimated patient population of 300,000 children and adults in Europe and the US alone.

Sensorion, a French clinical-stage biotech based in Montpellier, was founded in 2009 to develop novel therapies to restore, treat and prevent hearing loss disorders.

The GJB2 program draws on new research from Institut Pasteur which shows that the same genes that underly congenital deafness are also involved in severe forms of presbycusis (age-related hearing loss). These forms of presbycusis appearing to be monogenic types of hearing loss that can be potentially treated by gene therapy.

Although the types ofGJB2mutations in children and adults may differ, Sensorion says gene therapy could potentially provide a solution to both.

Mutations inGJB2are believed to alter a gap junction protein widely expressed in the inner ear, disturbing intercellular exchanges of molecules and leading to hearing loss that is severe-to-profound in a majority of cases.

Institut Pasteur research now shows three pathologies related to GJB2 mutations: congenital deafness;age-related hearing loss in adults; and progressive forms of hearing loss in children. Sensorion will prioritize the latter two forms, saying it is the first company to address these needs and offering the potential of large market opportunities.

The emergence of a new gene therapy target candidate validates our conviction that long-term solutions for restoring hereditary hearing loss will arise from an in-depth analysis of the "genetic landscape" of hearing loss," saidNawal Ouzren, CEO of Sensorion.

"It was clear that mutations in the GJB2 gene are important in severe to profound childhood hearing loss. However, the new discovery made by our collaborators at Institut Pasteur shows that alteration of this gene in adults offers new opportunities for Sensorion. It marks significant potential expansion of our pipeline and supports our goal of becoming a global leader in the field of gene therapies for hearing loss disorders.

Sensorions collaboration with Institut Pasteur initiated in 2019 has already led to gene therapy candidate programs in two other indications. Its USHER-CT gene therapy development program aims to restore inner ear function for patients suffering from Usher Syndrome Type 1 by providing a healthy copy of the USH1G gene coding for the SANS protein.

Meanwhile, the OTOF-GT gene therapy development program seeks to restore hearing in people with Otoferlin deficiency, one of the most common forms of congenital deafness.

Both of these have been proved in concept in preclinical studies.

Gene Therapy GS010 Safe, Well-Tolerated for LHON Patients – MD Magazine

Friday, February 19th, 2021

New data from GenSight Biologics showed promising results for lenadogene nolparvovec (LUMVOQ), an intravitreal gene therapy for leber hereditary optic neuropathy (LHON) caused by mutations in the mitochondrial ND4 gene.

Overall, the therapy was well-tolerated in patients, had a favorable safety profile, and was shown that it may lead to clinically meaningful improvements.

A team, led by Catherine Vignal-Clermont, MD, Rothschild Foundation Hospital, Paris, France, conducted an open-label, single-center, dose-escalation study that primarily assessed safety and tolerability of the gene therapy among 15 patients with LHON.

Therapeutic options for adolescent and adult patients with LHON are currently limited to idebenone (Raxone), a synthetic analog of coenzyme Q10, which is approved only in Europe under exceptional circumstances for treatment of LHON, Vignal-Clermont and team wrote.

They further acknowledged that no approved treatment exists in the United States.

REVEAL A Phase I/IIa Study

Among the exclusion criteria were vision loss in the fellow eye, glaucoma, diabetic retinopathy, macula edema, vitreoretinal disease, pathology of the retina or the optic nerve, retinal vein occlusion, narrow angles, optic neuropathy for other causes, or any other disease that would have an effect on visual function.

Eligible patients were divided into a dosing cohort to receive a single injection and then were followed-up immediately at day 3 for safety and efficacy assessments.

The investigators pursued further follow-up at weeks 1, 2, 4, 8, 12, 24, 36, and 48 post-treatment. Additional follow-up was performed at years 1.5, 2, 2.5, 3, 4, and 5.

The studys primary endpoint was the overall incidences of adverse events up to 5 years post-treatments for each dosing level and for the treatment as a whole.

Secondary endpoints included best corrected visual acuity (BCVA; calculated as logarithm of the minimal angle of resolution [LogMAR]), among other efficacy measurements.

Results

Throughout the follow-up period, the investigators noted no serious adverse events that were considered related to treatments.

Furthermore, patients did not experience unexpected adverse events nor grades 3 or 4 Common Terminology Criteria for Adverse Events.

Anterior chamber inflammation and vitritis were mostly managed with topical steroids, and ocular inflammation was considered to be dose limiting by the independent data safety monitoring board based on the benefits/risks for the subjects, the investigators wrote.

In terms of efficacy, the team reported that analysis of the LogMAR BCVA in both treated and untreated eyes showed clinically relevant and durable improvements compared with baseline.

As such, the mean improvement for the treated eye was -0.44 LogMAR and for the untreated eye was -0.49.

Thus, at 5 years post-treatment, the final value of LogMAR was +1.96 and +1.85, respectively, for the treated and untreated eyes.

As for those treated with the optimal dose level of 9 1010 viral genomes/eye (n = 6), the mean visual acuity improvement from baseline was 0.68 LogMAR for treated eyes and 0.64 LogMAR for untreated eyes.

The final mean value for the treated and untreated eyes were LogMAR +1.77 and +1.78, respectively.

While there was a meaningful improvement in visual acuity for REVEAL subjects, the final visual acuity was less favorable than that seen in the two subsequent pivotal phase III studies in which subjects were treated earlier during the course of their disease, Vignal-Clermont and colleagues wrote.

Nevertheless, the team acknowledged that these findings are a promising prelude to the Phase III RESCUE and REVERSE studies, which are running in tandem and currently assessing the efficacy of the single injection of the gene therapy in a larger population.

The study, "Safety of Intravitreal Gene Therapy for Treatment of Subjects with Leber Hereditary Optic Neuropathy due to Mutations in the Mitochondrial ND4 Gene: The REVEAL Study," was published online in BioDrugs.

bluebird bio ‘baffled’ after NICE rejects beta-thalassaemia gene therapy – – pharmaphorum

Friday, February 19th, 2021

Its back to the drawing board for bluebird bio and its discussions with NICE, which has rejected its beta thalassaemia gene therapy Zynteglo for regular NHS use in first draft guidance.

NICE is assessing Zynteglo (betibeglogene autotemcel), a one-off gene therapy for the condition, which can have life-threatening consequences and is associated with a curtailed life expectancy.

There is a curative treatment for people who rely on blood transfusions to survive and maintain their levels of red blood cells.

But haematopoietic stem cell transplantation is only possible when a donor with a matching human leukocyte antigen signature, within the correct age range, is available.

In this first draft guidance NICE raised a series of issues with Zynteglo, which bluebird has already agreed to supply at a confidential discount from its hefty price tag, which is around 1.57 million in Europe.

NICE said that data came from a small sample of patients and is using its standard discount rate of 3.5% to calculate the long-term benefits of the treatment.

The company has unsuccessfully pushed for a rate of 1.5%, which would attach more value to the long-term benefits of the therapy over a patients lifetime.

There was also a long list of other technical issues raised by NICE that count against Zynteglo in the assessment, including costs of fertility preservation and the number of simulated profiles in bluebirds data.

Nicola Redfern, bluebird bios UK general manager, said the first step is to present a new analysis of data addressing issues raised by NICE before there are any discussions about lowering the price again.

She pointed out that the dossier presented to NICE was compiled in 2019 and the company now has six years worth of follow-up data.

Redfern also added that this is the first time that NICE had assessed a gene therapy using its single technology assessment process, which is used for medicines likely to be used more widely on the NHS.

However Redfern was still surprised the rejection given the discussions with NICE so far in the process.

She said: Some of the specifics we thought we had covered off with them and discussed. The thing that baffled me most was the lack of understanding of this disease upon the people living with it.

The UK Thalassaemia Society noted NICEs citation of a UK patient reference report stating that 37% of respondents would immediately accept a referral to a transplant specialist and betibeglogene autotemcel if offered it.

Romaine Maharaj, executive director at UKTS, said: Most of our members are very excited about the new therapy developments and are keen to explore these treatment options.

Bone marrow transplant is only an option for a very small proportion of people with thalassaemia and so gene therapy offers a real potential alternative as a one-off resolution to this life-limiting condition.

What We’re Reading: Sickle Cell Gene Therapy Partnership; Global COVID-19 Cases on Decline; Storms Slow Vaccine Rollout – AJMC.com Managed Markets…

Friday, February 19th, 2021

Novartis is teaming up with the Gates Foundation to develop a gene therapy for sickle cell disease; the World Health Organization reports a drop in global cases of coronavirus disease 2019 (COVID-19); storms hinder vaccine rollout across the United States.

The Bill and Melinda Gates Foundation and Novartis are collaborating to discover and develop a one-step, one-time gene therapy treatment to cure sickle cell disease, STAT News reports. Although the cause of sickle cell disease is understood and the people it affects are known, a cure has been difficult to pin down. Through a 3-year partnership, the companies aim to create a treatment that is affordable and simple enough to treat individuals anywhere in the world, including sub-Saharan Africa, where disease prevalence is high. Current gene therapy approaches are complex and expensive, and they create treatments for patients one at a time. With an initial funding amount of $7.28 million, the companies ultimately hope to create an off-the-shelf product.

In the past week, the rate of new coronavirus disease 2019 (COVID-19) cases has declined by 16% around the world, according to the World Health Organization. This decline comes even as more virulent strains of COVID-19 have caused new outbreaks in some regions, The Washington Post reports. In addition to the decline in cases, over the past week there has been a 10% reduction in the number of deaths worldwide, with the greatest drop in cases seen in Europe and the Americas. In the United States alone, the number of new infections decreased by nearly 24% in the past week.

Deadly storms across the country hampered COVID-19 vaccination efforts on Tuesday, forcing appointment cancellations and delaying vaccine deliveries, according to the Associated Press. The surge of bad weather comes as the federal government rolled out new vaccination sites targeting hard-hit communities and seeks to boost the amount of vaccine sent to states to 13.5 million doses per week. Currently, the United States administers an average of 1.7 million doses per day, but the bad weather halted vaccinations in Pennsylvania, Illinois, Tennessee, and Missouri and is expected to disrupt shipments from facilities in Tennessee and Kentucky.

Selecta Biosciences and AskBio Initiate First-in-Human Dose-Escalation Study to Evaluate ImmTOR in Gene Therapy – PRNewswire

Friday, February 19th, 2021

WATERTOWN, Mass., and Research Triangle Park, N.C., Feb. 17, 2021 /PRNewswire/ --Selecta Biosciences, Inc. (NASDAQ: SELB) and Asklepios BioPharmaceutical, Inc. (AskBio), a wholly owned and independently operated subsidiary of Bayer AG, today announced the initiation of a Phase 1 dose-escalation trial of SEL-399, an adeno-associated viral serotype 8 (AAV8) empty vector capsid (EMC-101) containing no DNA combined with ImmTOR. The trial aims to determine the optimal dose of ImmTOR to mitigate the formation of antibodies to AAV8 capsids used in gene therapies.

"We are pleased to further evaluate ImmTOR's ability to reduce the formation of antibodies to AAV capsids and potentially enable gene therapy redosing by having initiated this dose-escalation study of SEL-399," said Carsten Brunn, Ph.D., president and chief executive officer of Selecta. "This trial builds upon our strong preclinical data in non-human primates and marks the first time that ImmTOR in conjunction with an AAV capsid has been dosed in humans, which is a significant milestone. Data from this study will inform the design of future clinical trials in patients as we seek to unlock the full potential of gene therapy."

The dose-escalation trial of SEL-399 is designed to evaluate the safety and preliminary efficacyof ImmTOR in gene therapy. The study, being conducted in healthy volunteers at the SGS Life Sciences Clinical Pharmacology Unit in Antwerp, Belgium, plans to enroll up to 45 subjects to investigate increasing doses of ImmTOR and EMC-101. Subjects will be randomized in a 3:1 ratio of ImmTOR plus empty AAV8 capsid to empty capsid alone. Preliminary efficacy will be measured by assessing levels of AAV8-specific neutralizing antibodies.

Jude Samulski, Ph.D., chief scientific officer and co-founder of AskBio said, "By determining the dose at which ImmTOR is able to inhibit the formation of AAV-specific antibodies,this study could be a significant first step toward overcoming some of the unwanted immune responses associated with gene therapies. We look forward to using these findings to inform future studies as we work to develop strategies for repetitive dosing of AAV, thus extending durability of expression."

Selecta and AskBio expect to report initial results from this clinical trial in the fourth quarter of 2021.

GenSight Biologics’ gene therapy proves safe in LHON trial – Clinical Trials Arena

Friday, February 19th, 2021

GenSight Biologics has reported that results from the Phase I/IIa REVEAL clinical trial of LUMEVOQ (lenadogene nolparvovec) gene therapy demonstrated a favourable safety profile in individuals with ND4 Leber hereditary optic neuropathy (LHON).

The trial also determined the dose used in the Phase III RESCUE and REVERSE trials.

Launched in 2014, the open-label, single-centre, dose escalation study analysed the safety and tolerability of LUMEVOQ in 15 participants with ND4 LHON who were followed for up to five years after administering a single intravitreal injection to their worst-affected eye.

Participants were enrolled in four cohorts of three subjects each, with each cohort given increasing doses of the gene therapy.

Dose escalation continued only after a safety evaluation by an independent data safety monitoring board (DSMB). A final extension cohort received the dose that the DSMB determined to have the best benefit-risk ratio among those administered to the four previous cohorts.

Data showed that LUMEVOQ was well-tolerated over the follow-up period of five years, with no serious adverse events noted.

These results are the first to show the favourable safety profile of the gene therapy while hinting at the efficacy analysed in the Phase III trials.

This safety profile was then affirmed in the Phase III RESCUE and REVERSE trials.

GenSight co-founder Dr Jos-Alain Sahel said: This study confirms the gene therapys favourable long-term safety and further demonstrates that the trends that were initially observed have been maintained for at least five years.

GlobalData's TMT Themes 2021 Report tells you everything you need to know about disruptive tech themes and which companies are best placed to help you digitally transform your business.

The company noted that REVEAL trial data and analyses were main components of the evidence package submitted to the European Medicines Agency (EMA) last September.

The submission was made seeking Marketing Authorisation Application (MAA) for LUMEVOQ for treating patients with visual loss due to ND4 LHON. The EMA decision is expected in the fourth quarter of this year.

UC San Diego: First-in-Human Clinical Trial to Assess Gene Therapy for Alzheimers Disease – India Education Diary

Friday, February 19th, 2021

Researchers at University of California San Diego School of Medicine have launched a first-in-human Phase I clinical trial to assess the safety and efficacy of a gene therapy to deliver a key protein into the brains of persons with Alzheimers disease (AD) or Mild Cognitive Impairment (MCI), a condition that often precedes full-blown dementia.

The protein, called brain-derived neurotrophic factor or BDNF, is part of a family of growth factors found in the brain and central nervous system that support the survival of existing neurons and promote growth and differentiation of new neurons and synapses. BDNF is particularly important in brain regions susceptible to degeneration in AD.

In previous published research, principal investigator Mark Tuszynski, MD, PhD, professor of neuroscience and director of the Translational Neuroscience Institute at UC San Diego School of Medicine, and colleagues described the prevention and reversal of brain cell degeneration and death in animal models.

Mark TuszynskiMark Tuszynski, MD, PhD, professor of neuroscience and director of the Translational Neuroscience Institute at UC San Diego School of Medicine.

We found that delivering BDNF to the part of the brain that is affected earliest in Alzheimers disease the entorhinal cortex and hippocampus was able to reverse the loss of connections and to protect from ongoing cell degeneration, said Tuszynski. These benefits were observed in aged rats, aged monkeys and amyloid mice.

Amyloid mice are genetically engineered to inherit a mutation in the gene encoding the amyloid precursor protein, and as a result develop amyloid plaques aggregates of misfolded proteins in the brain that are considered a hallmark characteristic of AD.

BDNF is normally produced throughout life in the entorhinal cortex, an important memory center in the brain and one of the first places where the effects of AD typically appear in the form of short-term memory loss. Persons with AD have diminished levels of BDNF.

But BDNF is not easy to work with. It is a large molecule and cannot pass through the blood-brain barrier. As a result, researchers will use gene therapy in which a harmless adeno-associated virus (AAV2) is modified to carry the BDNF gene and injected directly into targeted regions of the brain, where researchers hope it will prompt production of therapeutic BDNF in nearby cells.

The injections are precisely controlled to contain exposure to surrounding degenerating neurons since freely circulating BDNF can cause adverse effects, such as seizures.

The three-year-long trial will recruit 12 participants with either diagnosed AD or MCI to receive AAV2-BDNF treatment, with another 12 persons serving as comparative controls over that period.

This is the first safety and efficacy assessment of AAV2-BDNF in humans. A previous gene therapy trial from 2001 to 2012 using AAV2 and a different protein called nerve growth factor (NGF) found heightened growth, axonal sprouting and activation of functional markers in the brains of participants.

The BDNF gene therapy trial in AD represents an advance over the earlier NGF trial, said Tuszynski. BDNF is a more potent growth factor than NGF for neural circuits that degenerate in AD. In addition, new methods for delivering BDNF will more effectively deliver and distribute it into the entorhinal cortex and hippocampus.

Despite billions of dollars of research investment and decades of effort, there are only two symptomatic treatments for AD. There is no cure or approved way to slow or stop progression of the neurological disorder that afflicts more than 5 million Americans and is the sixth leading cause of death in the United States.

Numerous clinical trials are ongoing to assess pharmaceutical remedies. Tuszynski said gene therapy, which debuted in 1980 and has been tested on multiple diseases and conditions, represents a different approach to a disease that requires new ways of thinking about the disease and new attempts at treatments.

We hope to build on recent successes of gene therapy in other diseases, including a breakthrough success in the treatment of congenital weakness in infants (spinal muscular atrophy) and blindness (Leber Hereditary Optic Neuropathy, a form of retinitis pigmentosa), Tuszynski said.

BDNF gene therapy has the potential, unlike other AD therapies currently under development, to rebuild brain circuits, slow cell loss and stimulate cell function. We are looking forward to observing the effects of this new effort in patients with AD and MCI.

The full title of the research project is "Targeting the innate immune system to block acute inflammatory and chronic immune response to transgene and AAV vector in DMD".Professor Nagaraju's research will receive funding from the organizations in the amount of $350,000.

These are promising times for research into Duchenne muscular dystrophy (Duchenne). Several companies are now testing an approach that uses a shortened dystrophin gene to replace the faulty dystrophin gene in Duchenne. This is known as gene transfer using micro-dystrophin, or more commonly, gene therapy. The companies are using viruses known as AAVs (adeno-associated viruses) to deliver the therapy.

However, challenges exist in getting this treatment to the entire Duchenne population. This is mainly because of immune responses: some patients have pre-existing antibodies to the AAVs. This means they will not, currently, be able to have the treatment because their bodies will recognize the virus and stop it from delivering the micro-dystrophin to the cells. In addition, as gene therapy is a new treatment, it is not yet clear if another dose will be required at a later stage, and it is not currently possible to re-dose with the same AAV.

This is why Duchenne UK & PPMD launched a call for projects last year that would specifically address this challenge.

The organizations received a large number of proposals, and three were taken forward for final review from a panel of highly qualified, specialized scientists. They looked at a wide variety of factors, including significance to the Duchenne community, and the ability to translate the research into treatments for patients.

Professor Nagaraju's research is looking at blocking the mechanism by which the body is able to recognise an AAV virus and mount an immune response to it. Importantly, he is using medicines that are already in use in humans, in an approach known as repurposing.

If this approach were successful, it would allow more micro-dystrophin to get to the cells, potentially requiring a lower dose of the AAV than is currently being administered in the trials. It may also allow patients who have already been dosed with gene therapy to receive further doses. Further to this, by using repurposed drugs, this treatment should be more easily transferable to patients. Professor Nagaraju believes that "targeting initial immune recognition pathways is one way to improve efficacy and safety profiles of AAV mediated gene therapy".

PPMD's Founding President & CEO, Pat Furlong, and Duchenne UK's CEO, Emily Crossley explained in a joint statement:"Supporting patients and accelerating innovative research is at the heart of what we do at Duchenne UK and PPMD. We are pleased to partner with each other and award this grant. Gene therapy is offering great promise, but there are challenges associated with the immune response which are limiting the rate of progress and a barrier to ensuring all patients can have access to these potentially transformative therapies.We would like to thank all those who participated and supported our Joint Grant Call and are very much looking forward to working with Professor Nagaraju on this vitally important project for the Duchenne community."

Europe Cell and Gene Therapy Market Report 2021-2026: Prominent Players are Novartis, Spark Therapeutics, Amgen, Gilead Sciences & Organogenesis -…

Friday, February 19th, 2021

Dublin, Feb. 15, 2021 (GLOBE NEWSWIRE) -- The "Europe Cell and Gene Therapy Market - Industry Outlook and Forecast 2021-2026" report has been added to ResearchAndMarkets.com's offering.

In-depth Analysis and Data-driven Insights on the Impact of COVID-19 Included in this Europe Cell and Gene Therapy Market Report

The Europe cell and gene therapy market by revenue is expected to grow at a CAGR of over 23% during the period 2021-2026.

The global cell and gene therapy market is observing significant mergers and acquisition activities, product sales, and new market authorizations. In 2026, the market is expected to grow almost four times more than the current value, with new product approvals expected annually. Although initial product approvals have been for relatively small patient groups, the significant pipeline of cell & gene therapy studies for diseases such as hemophilia and various forms of blindness will significantly expand.

In addition, the Europe market is witnessing steady growth due to the increased availability of funds from several public and private institutes. There is increased support from regulatory bodies for product approvals and fast-track product designations, which encourage vendors to manufacture products at a fast rate. Moreover, with over 237 regenerative medicines companies headquartered in Europe, the region is seen as the favorite destination for cell and gene therapy manufacturing.

Europe Cell and Gene Therapy Market Segmentation

The Europe cell and gene therapy market research report includes a detailed segmentation by product, end-user, application, geography. A high potential to treat several chronic diseases, which cannot be effectively treated/cured through conventional methods otherwise, is propelling the growth of gene therapies. Gene therapies are regarded as a potential revolution in the health sciences and pharmaceutical fields.

The number of clinical trials investigating gene therapies is increasing in Europe, despite the limited number of products that have successfully reached the market. However, gene therapies show slow progress and promising prospect in terms of treatments. High support from regulatory bodies to commercialize these products and make them affordable to patients is another important factor contributing the market growth.

Delivering cell and gene therapies requires specialized facilities, capabilities, and clinician skills. Therefore, manufacturers are working in tandem with chosen treatment centers (hospitals) to establish the protocols and procedures necessary to receive the product and therapies. While cell therapies represent a paradigm shift in the treatment of several incurable, chronic diseases, with durable responses and long-term disease control measures, hospitals appear an ideal location to carry out these procedures.

Hospitals are growing at a significant rate due to the increasing target population in Europe. Tier-I hospitals are proving to be sought-after network partners for cell and gene therapy developers. They tend to be in major population centers, have adequate financial and personnel resources, and value the prestige that comes with being the first movers in an innovative treatment area.

Oncology accounted for a share of over 30% in 2020. While cancer treatments have evolved and undergone massive developments in recent years, it continues to be one of the deadliest diseases confronted by humans. Traditional cancer therapies have a curative effect in the short term; however, they have side effects, thereby decreasing the patient's quality of life. Cell and gene therapies for certain types of cancers have been promising results. The chimeric antigen receptor- (CAR-) T cell therapy is one of the most recent innovative immunotherapies and is rapidly evolving.

CAR-T cell therapies are developing rapidly, and many clinical trials have been established on a global scale, which has high commercial potential for the treatment of cancer. Immunotherapies based on CAR-T cells go one step further, engineering the T cells themselves to enhance the natural immune response against a specific tumor antigen. CAR-T clinical trials have shown high remission rates, up to 94%, in severe forms of blood cancer, thereby increasing the market growth.

INSIGHTS BY VENDORS

Novartis, Spark Therapeutics, Amgen, Gilead Sciences, and Organogenesis are the leading players in the Europe cell and gene therapy market. The market offers tremendous growth opportunities for existing and future/emerging players on account of the presence of a large pool of target patient population with chronic diseases such as cancer, wound disorders, diabetic foot ulcer, CVDs, and other genetic disorders.

Beti-Cel Gene Therapy Frees Patients With Beta-Thalassemia From Red Blood Cell Transfusions – OncLive

Friday, February 19th, 2021

Betibeglogene autotemcel (beti-cel), a one-time gene therapy, enabled durable transfusion independence in most patients with transfusion-dependent -thalassemia (TDT) who were treated across 4 clinical studies.

Of 60 patients enrolled overall, 17 of 22 (77%) treated in the 2 phase 1/2 studies were able to stop packed red blood cell transfusions. In the 2 phase 3 studies, which used a refined manufacturing process resulting in improved beti-cel characteristics, 89% (n = 31/35) of patients with at least 6 months of follow-up achieved transfusion independence for more than 6 months,1 reported Suradej Hongeng, MD, during the virtual 2021 Transplantation & Cellular Therapy Meetings.

The median follow-up after beti-cel infusion in the 4 studies has been 24.8 months (range, 1.1-71.8).

With up to 6 years of follow-up, 1-time beti-cel gene therapy enabled durable transfusion independence in the majority of patients, said Hongeng, from Ramathibodi Hospital of Mahidol University, in Bangkok, Thailand.

Patients who achieved transfusion independence experienced a 38% median reduction in liver iron concentration (LIC) from baseline to month 48. The median reduction in LIC was 59% in patients with a baseline LIC more than 15 mg/g dw. A total of 21 of 37 (57%) patients who achieved transfusion independence have stopped iron chelation for 6 months or longer, with a median duration of 18.5 months from stopping iron chelation to last follow-up.

Erythropoiesis as determined by soluble transferrin receptor level was also improved in transfusion-independent patients. Bone marrow biopsies showed improvement in the myeloid:erythroid ratio.

Beti-cel adds functional copies of a modified form of the -globin (A-T87Q-globin) gene into a patients own hematopoietic stem cells (HSCs) through transduction of autologous CD34+ cells using a BB305 lentiviral vector. Following single-agent busulfan myeloablative conditioning, beti-cel is infused, after which the transduced HSCs engraft and reconstitute red blood cells containing functional adult hemoglobin derived from the gene therapy.

Of the 60 patients treated, 43 were genotype non-/ and 17 were / . The median age at consent was 20 years in the phase 1/2 trials and 15 years in the phase 3 trials. Median LIC at baseline was 7.1 and 5.5 mg Fe/g dw, respectively, and median cardiac T2 was 34 and 37 msec, respectively. The vector copy number was 0.8 in the phase 1/2 trial and 3.0 in the phase 3 study. Additionally, 32t and 78t CD34+ cells were transduced, respectively.

The phase 1/2 studies showed promising results but lower achievement of transfusion independence in patients with the / genotype, leading to a refinement in the manufacturing process, which resulted in a higher number of transduced cells and a higher number of vector copy number, said Hongeng.

The median time to neutrophil engraftment was 22.5 days and the median time to platelet engraftment was 44 days. Lymphocyte subsets were generally within the normal range after beti-cel infusion, which is different from allogeneic stem cell [transplantation], which is probably around 6 months to a year to get complete recovery of immune reconstitution, he said. The median duration of hospitalization was 42 days.

All patients were alive at the last follow-up (March 3, 2020). Eleven of 60 (18%) of patients experienced at least 1 adverse event (AE) considered related or possibly related to beti-cel, the most common being abdominal pain (8%) and thrombocytopenia (5%). Serious AEs were those expected after myeloablative conditioning: veno-occlusive liver disease (8%), neutropenia (5%), pyrexia (5%), thrombocytopenia (5%), and appendicitis, febrile neutropenia, major depression, and stomatitis (3% each).

Of the 7 patients experiencing veno-occlusive liver disease, 3 were of grade 4 and 2 were of grade 3. Two other patients had grade 2 veno-occlusive disease. There were no cases of insertional oncogenesis.

Persistent vector-positive hematopoietic cells and durable HbaT87Q levels supported stable total hemoglobin over time. In phase 3 trials, the median peripheral blood vector copy number was 1.2 c/dg at month 12 and 2.0 c/dg at month 24, and the median total hemoglobin was 11.5 g/dL at month 12 and 12.9 g/dL at month 24.

The weighted average of hemoglobin during transfusion independence in the phase 1/2 trials was 10.4 g/dL, and patients were transfusion-independent for a median of 51.2 months. In the phase 3 studies, the weighted average of hemoglobin during transfusion independence was 11.9 g/dL, and patients were transfusion-independent for a medium 17.7 months.

Efficacy and safety of betibeglogene autotemcel (beti-cel; LentiGlobin for -thalassemia) gene therapy in 60 patients with transfusion-dependent -thalassemia (TDT) followed for up to 6 years post-infusion.

Scientists use machine learning to tackle a big challenge in gene therapy – STAT

Sunday, February 14th, 2021

As the world charges to vaccinate the population against the coronavirus, gene therapy developers are locked in a counterintuitive race. Instead of training the immune system to recognize and combat a virus, theyre trying to do the opposite: designing viruses the body has never seen, and cant fight back against.

Its OK, really: These are adeno-associated viruses, which are common and rarely cause symptoms. That makes them the perfect vehicle for gene therapies, which aim to treat hereditary conditions caused by a single faulty gene. But they introduce a unique challenge: Because these viruses already circulate widely, patients immune systems may recognize the engineered vectors and clobber them into submission before they can do their job.
