ACT Announces Approval to Treat Additional Stargardt’s Disease Patients with Higher RPE Dosage in Both U.S. and …

October 9th, 2012 5:19 pm

MARLBOROUGH, Mass.--(BUSINESS WIRE)--

Advanced Cell Technology, Inc. (ACT; OTCBB: ACTC), a leader in the field of regenerative medicine, announced today that the Data and Safety Monitoring Board (DSMB), an independent group of medical experts closely monitoring the Companys three ongoing clinical trials, has authorized the Company to move forward with enrollment and treatment of second and third additional patients with Stargardts macular dystrophy (SMD) in the second patient cohort of its U.S. trial for the condition. Additionally, the DSMB has authorized the Company to treat all three patients in the second cohort of its European trial for SMD.

The UK Medicines and Healthcare products Regulatory Agency (MHRA) recently approved a protocol modification to the DSMB review, streamlining the process, allowing the company to treat the first patient in a new cohort if the DSMB has allowed this in the US study, and once clearance has been received in the US trial to treat the next two patients in the US cohort. This would also allow for treatment of the UK patients without an additional review by the DSMB. Moreover, according to the protocol for both trials, each patient in the second cohort will be injected with 100,000 human embryonic stem cell (hESC)-derived retinal pigment epithelial (RPE) cells, up from 50,000 in the first cohort.

This authorization to treat the next five patients in the second, higher-dosage cohort in both our clinical trials for SMD represents a significant step forward for our clinical programs, commented Gary Rabin, chairman and CEO of ACT. We are also encouraged with the MHRAs approval of the DSMBs streamlined review process. Clearly this has the potential to help accelerate the pace of our European trial.

ACT is conducting three clinical trials in the U.S. and Europe using hESC-derived RPE cells to treat forms of macular degeneration, SMD and dry age-related macular degeneration (dry AMD). Each trial will enroll a total of 12 patients, with cohorts of three patients each in an ascending dosage format, from 50,000 hESC-derived RPE cells in the first patient cohort to 200,000 in the last and final cohort. These trials are prospective, open-label studies, designed to determine the safety and tolerability of hESC-derived RPE cells following sub-retinal transplantation into patients with dry-AMD or SMD at 12 months, the studys primary endpoint.

We are eagerly anticipating treating these final two patients in the second cohort of our U.S. trial for SMD, and all three patients in the second cohort of our E.U. trial, commented Robert Lanza, M.D., ACTs chief scientific officer. We are encouraged by the preliminary data in the first patient in this second, higher-dosage cohort and look forward to gathering more data.

Further information about patient eligibility for ACTs SMD studies in the U.S. and E.U. as well as its dry AMD study are available atwww.clinicaltrials.gov,with the following Identifiers: NCT01345006 (U.S. SMD), NCT01469832 (E.U. SMD), and NCT01344993 (dry AMD).

Regenerative medicine could be 'next big thing' for Va. biotech

October 9th, 2012 5:19 pm

Regenerative medicine, a field that didn't exist 20 years ago and contains techniques seemingly straight out of science fiction, could be the next big thing in Virginia's biotechnology sector.

That's the opinion of Roy Ogle, an expert in the field who works at Old Dominion University as head of its new school of Medical Diagnostic and Translational Sciences.

So what is regenerative medicine? Simply put, it's the process of re-growing human cells to repair damaged tissues and organs.

In a meeting Thursday hosted by the Virginia Biotechnology Association, Ogle and Brian Pollok, principal of Rapidan BioAdvisors, discussed one of the field's newest developments: induced pluripotent stem cells, or iPSCs.

Let's go back to high school biology: Perhaps you remember embryonic stem cells. These cells can differentiate into different types of cells skin, blood, bone, muscle before a baby is born. But their use in scientific research has become controversial and difficult.

So scientists needed a new way to develop stem cells. iPSCs are already formatted cells that are "induced," or returned, to their original state as a stem cell. Then that stem cell can be reprogrammed to become a different type of cell. For example, a researcher can take a red blood cell, turn it into an iPSC, and then turn that into a muscle cell. (Yeah, our jaw dropped at this point, too). So you get most of the benefits of an embryonic stem cell without the controversy.

What's that mean for the business community?

"Ten or 20 years from now, we could have a way to do cell replacements and make a new spinal cord or new and healthy muscles," Ogle said. "But right now, there are genetic discoveries and methods of development with a giant potential that a small company can sell to (pharmaceutical giants such as) Roche or Sanofi-Aventis."

Ogle said this sort of intermediate work after invention but before the science is proven enough for big pharma to get involved is the perfect space for startups, especially those affiliated with research universities. He said small companies are best placed to do this work and sell the results to big companies because a startup is better suited to tolerate the risk and uncertainty.

"While we think about the long-term development as scientists, there are applications right now where we could serve society and make a lot of money," he said.

NeoStem Announces Very Small Embryonic-Like Cells (VSEL(TM)) Publication in Stem Cells and Development

October 9th, 2012 5:14 pm

NEW YORK, Oct. 8, 2012 (GLOBE NEWSWIRE) -- NeoStem, Inc. (NYSE MKT:NBS), an emerging leader in the fast growing cell therapy market, announced today that data from its collaborative studies with the University of Michigan School of Dentistry further expands the therapeutic potential of its proprietary regenerative cell therapy product, "VSELSTM" (very small embryonic-like stem cells), by demonstrating bone regeneration capabilities in a study published online ahead of print1 in the journal Stem Cells and Development (DOI: 10.1089/scd.2012.0327). The paper highlights that human VSEL stem cells form human bone when implanted in the bone tissue of SCID mice.

VSELs are a population of stem cells found in adult bone marrow with potential regenerative properties similar to those of embryonic stem cells. NeoStem has shown that these cells can be mobilized into the peripheral blood, enabling a minimally invasive means for collecting what NeoStem believes to be a population of stem cells that have the potential to achieve the positive benefits associated with embryonic stem cells without the ethical or moral dilemmas or the potential negative effects known to be associated with embryonic stem cells.

This published controlled study, funded by NIH and led by Dr. Russell Taichman, Major Ash Collegiate Professor and Co-Director of the Scholars Program in Dental Leadership Department of Periodontics & Oral Medicine, University of Michigan and Dr. Aaron Havens, Department of Orthodontics and Pediatric Dentistry at University of Michigan, involved isolating G-CSF mobilized VSEL stem cells from the blood of healthy donors and transplanting them into burr holes made in the cranial bones of SCID mice. After three months, it was observed that the implanted VSEL stem cells had differentiated into human bone tissue in the crania of the mice. Dr. Taichman stated, "I believe this work represents a true partnership between Industry and Academic Institutions. Our findings that VSEL cells can generate human bone in animals would not have been feasible without the help and vision that Dr. Denis Rodgerson and his team at NeoStem brought to the table. It was my privilege to have been a part of this collaborative effort, and I see the resulting data as a significant milestone in stem cell therapy development. It is truly inspiring."

Dr. Robin Smith, Chairman and CEO of NeoStem, added, "This is very exciting data that we believe will be the foundation for future VSEL stem cell studies of bone regeneration in humans. We look forward to moving the development work from the laboratory into the clinic to develop a therapeutic stem cell product to enhance bone formation in humans."

Britain’s Gurdon, Japan’s Yamanaka share Nobel medicine prize for stem cell research

October 9th, 2012 8:23 am

NEW YORK, N.Y. - Two scientists from different generations won the Nobel Prize in medicine Monday for the groundbreaking discovery that cells in the body can be reprogrammed into completely different kinds, work that reflects the mechanism behind cloning and offers an alternative to using embryonic stem cells.

The work of British researcher John Gurdon and Japanese scientist Shinya Yamanaka who was born the year Gurdon made his discovery holds hope for treating diseases like Parkinson's and diabetes by growing customized tissue for transplant.

And it has spurred a new generation of laboratory studies into other illnesses, including schizophrenia, which may lead to new treatments.

Basically, Gurdon, 79, and Yamanaka, 50, showed how to make the equivalent of embryonic stem cells without the ethical questions those very versatile cells pose, a promise scientists are now scrambling to fulfil.

Once created, these "blank slate" cells can be nudged toward developing into other cell types. Skin cells can ultimately be transformed into brain cells, for example.

Just last week, scientists reported turning skin cells from mice into eggs that produced baby mice, a possible step toward new fertility treatments.

Gurdon and Yamanaka performed "courageous experiments" that challenged scientific opinion, said Doug Melton, co-director of the Harvard Stem Cell Institute.

"Their work shows ... that while cells might be specialized to do one thing, they have the potential to do something else," Melton said. It "really lays the groundwork for all the excitement about stem cell biology."

Another Harvard stem cell researcher, Dr. George Daley said, "I don't think anybody is surprised" by the award announcement. "The fact that these two share it together is inspired."

In announcing the $1.2 million award, the Nobel committee at Stockholm's Karolinska Institute said the work has "revolutionized our understanding of how cells and organisms develop."

Stem Cell Scientists Gurdon and Yamanaka Win Nobel Prize in Medicine

October 9th, 2012 8:23 am

JUDY WOODRUFF: Next, to the 2012 Nobel Prizes. The first was awarded today for groundbreaking work in reprogramming cells in the body.

Ray Suarez looks at those achievements.

MAN: The Nobel Assembly at Karolinska Institute has today decided to award the Nobel Prize in Physiology or Medicine,2012 jointly to John B. Gurdon and Shinya Yamanaka.

RAY SUAREZ: The two scientists are from two different generations and celebrated today's announcement half-a-world apart.

But today they were celebrated together for their research that led to a groundbreaking understanding of how cells work.

Sir John Gurdon of CambridgeUniversity was awarded for his work in 1962. He was able to use specialized cells of frogs, like skin or intestinal cells, to generate new tadpoles and show DNA could drive the formation of all cells in the body.

Forty years later, Dr. Yamanaka built on that and went further. He was able to turn mature cells back into their earliest form as primitive cells. Those cells are in many ways the equivalent of embryonic stem cells, because they have the potential to develop into specialized cells for heart, liver and other organs.

Dr. Shinya Yamanaka is currently working at KyotoUniversity. Embryonic stem cells have had to be harvested from human embryos, a source of debate and considerable controversy.

For Gurdon, the prize had special meaning. At a news conference in London, he recalled one schoolteacher's reaction to his desire to study science.

JOHN GURDON, co-winner, Nobel Prize For Medicine or Physiology: It was a completely ridiculous idea because there was no hope whatever of my doing science, and any time spent on it would be a total waste of time, both on my part and the part of the person having to teach him. So that terminated my completely -- completely terminated my science at school.

Cell rewind wins medicine Nobel

October 9th, 2012 8:23 am

John Gurdon (left) and Shinya Yamanaka showed how to reprogram cells into their embryonic states.

J. Player/Rex Features; Aflo/Rex Features

The discovery that cells can be reprogrammed to an embryonic-like state has won this years Nobel Prize in Physiology or Medicine for two leading lights of stem-cell research: John Gurdon and Shinya Yamanaka.

Reprogrammed cells regain pluripotency, the potential to differentiate into many mature cell types. Many researchers hope that cells created in this way will eventually be used in regenerative medicine, providing replacement tissue for damaged or diseased organs. The field has become one of the hottest in biology, but the prizewinners discoveries were not without controversy when they were made.

Gurdon, who is based at the Gurdon Institute in Cambridge, UK, was the first person to demonstrate that cells could be reprogrammed, in work published 50years ago1. At the time, scientists believed that cellular specialization was a one-way process that could not be reversed. Gurdon overturned that dogma by removing the nucleus from a frog egg cell and replacing it with the nucleus from a tadpoles intestinal cell. Remarkably, the process was able to turn back the cellular clock of the substitute nucleus. Although it had already committed to specialization, inside the egg cell it acted like an eggs nucleus and directed the development of a normal tadpole.

Gurdon was a graduate student at the University of Oxford, UK, when he did the work. He received his doctorate in 1960 and went on to do a postdoc at the California Institute of Technology in Pasadena, leaving his frogs in Europe. He did not publish the research until two years after he got his PhD, once he was sure that the animals had matured healthily. I was a graduate student flying in the face of [established] knowledge, he says. There was a lot of scepticism.

Mammalian cells did not prove as amenable to this process, known as cloning by nuclear transfer, as frog cells. It was nearly 35years before the first cloned mammal Dolly the sheep was born, in 1996. Dolly was the only live birth from 277 attempts, and mammalian cloning remained a hit-and-miss affair.

Scientists were desperate to improve the efficiency of the system and to understand the exact molecular process involved. That is where Shinya Yamanaka of Kyoto University, Japan, made his mark. Yamanaka who was born the year that Gurdon published his formative paper used cultured mouse cells to identify the genes that kept embryonic cells immature, and then tested whether any of these genes could reprogram mature cells to make them pluripotent.

In the mid-2000s, the stem-cell community knew that Yamanaka was close. I remember when he presented the data at a 2006 Keystone symposium, says Cdric Blanpain, a stem-cell biologist at the Free University of Brussels. At that time he didnt name them and everyone was betting what these magic factors could be.

A few months later, attendees at the 2006 meeting of the International Society for Stem Cell Research in Toronto, Canada, packed out Yamanakas lecture. The audience waited in silence before he announced his surprisingly simple recipe: activating just four genes was enough to turn adult cells called fibroblasts back into pluripotent stem cells2. Such induced pluripotent stem (iPS) cells could then be coaxed into different types of mature cell types, including nerve and heart cells.

Fingers crossed at AIIMS after stem cell transplant for MS, first in country

October 8th, 2012 11:38 pm

Doctors at the All India Institute of Medical Sciences (AIIMS) have conducted a stem cell transplant on a multiple sclerosis (MS) patient. They believe this is the first recorded case of an autologous stem cell therapy where the donor and recipient are the same person for MS in the country.

Six months after the transplant, doctors say the spread of MS, an autoimmune disease that affects the brain and spinal cord, appears to have been contained but the therapy cannot be declared a success until the patient is monitored for at least a year.

International trials have demonstrated that this transplant can restrict the spread of the disease in advanced patients, and may even reverse symptoms in early stages in some patients.

Thirty-two-year-old Rohit Yadav, a commerce graduate from Delhi University, was diagnosed with the neurological disorder in 2010. In March this year, after trying all possible conventional treatment options, doctors at AIIMS finally decided on stem cell therapy.

Dr Kameshwar Prasad, professor of neurology who has been monitoring Yadav, said: The primary purpose of autologous stem cell transplant is to control the spread of lesions. We extract the patients own stem cells, treat and inject the stem cells back. Ever since the procedure, the patient has been completely stable. To the best of our knowledge, this is the first case of stem cell therapy for MS.

In MS, the bodys own immune system attacks the myelin sheath that coats nerves, slowly destroying the central nervous system. Symptoms range from numbness and weakness in the limbs to sudden loss of balance and coordination, blurred vision and paralysis and, at the most advanced stage, disability.

Nobel Prize In Medicine Awarded To Stem Cell Researchers

October 8th, 2012 5:13 pm

The Nobel Prize in Medicine or Physiology for 2012 was awarded jointly to British scientist John B. Gurdon and Japanese scientist Shinya Yamanaka for their work in stem cell research, the Karolinska Institute in Stockholm announced Monday.

The announcement opens the prestigious award season for this year while the speculation over literature and peace prizes is rife.

"These groundbreaking discoveries have completely changed our view of the development and specialization of cells," the Nobel Assembly at Sweden's Karolinska Institute said in a statement on its website.

We now understand that the mature cell does not have to be confined forever to its specialized state. Textbooks have been rewritten and new research fields have been established. By reprogramming human cells, scientists have created new opportunities to study diseases and develop methods for diagnosis and therapy," the statement said.

Gurdon discovered in 1962 that the specialization of cells is reversible. Yamanaka discovered more than 40 years later in 2006 how the intact mature cells in mice could be reprogrammed to become immature stem cells. These groundbreaking discoveries have completely changed our view of the development and cellular specialization, the institute has said.

Gurdon was born in 1933 in Dippenhall, the U.K, and received his Doctorate from the University of Oxford in 1960 and was a postdoctoral fellow at the California Institute of Technology. Gurdon is currently at the Gurdon Institute in Cambridge.

Yamanaka was born in Osaka, Japan, in 1962 and received his MD in 1987 at Kobe University and was trained as an orthopedic surgeon. Yamanaka obtained his PhD at Osaka University in 1993. Yamanaka is currently Professor at Kyoto University and is also affiliated to the Gladstone Institute.

Stem Cell Researchers Share Nobel Medicine Prize

October 8th, 2012 5:13 pm

British researcher John Gurdon and Shinya Yamanaka from Japan have shared the Nobel prize for medicine or physiology.

The two pioneers of stem cell research were awarded the prize for transforming specialised cells into stem cells, which can become any other type of cell in the body.

John Gurdon discovered in 1962 that the specialisation of cells is reversible. In a classic experiment, he replaced the immature cell nucleus in an egg cell of a frog with the nucleus from a mature intestinal cell. This modified egg cell developed into a normal tadpole. The DNA of the mature cell still had all the information needed to develop all cells in the frog.

Shinya Yamanaka discovered more than 40 years later, in 2006, how intact mature cells in mice could be reprogrammed to become immature stem cells. Surprisingly, by introducing only a few genes, he could reprogram mature cells to become pluripotent stem cells, i.e. immature cells that are able to develop into all types of cells in the body.

These groundbreaking discoveries have completely changed our view of the development and cellular specialisation.

By reprogramming human cells, scientists have created new opportunities to study diseases and develop methods for diagnosis and therapy.

Stem cell pioneers win Nobel medicine honors

October 8th, 2012 5:13 pm

The 2012 Nobel Prize for medicine has been awarded to stem cell researchers John Gurdon and Shinya Yamanaka of Britain and Japan. They take the first Nobel prize of the year, with a flurry to follow over the next week.

Judges in Stockholm said on Monday that the medicine prize had been awarded to the researchers "for the discovery that mature cells can be reprogrammed to become pluripotent," saying that this discovery had "revolutionized our understanding of how cells and organisms develop."

Gurdon and Yamanaka are stem cell researchers who are seeking ways to obtain embryonic stem cells - a kind of genetic blank slate, cells that can be 'programmed' to take on many different forms and perform different functions - from the cells of an adult. Embryos themselves are another more controversial source of stem cells.

"We are trying to find ways of obtaining embryo cells from the cells of an adult," Gurdon writes on his Gurdon Institute website. "The eventual aim is to provide replacement cells of all kinds starting from usually obtainable cells of an adult individual."

The British scientist also said such a system was advantageous because the stem cells could be obtained from the patient themselves, reducing the risk of rejection when they were employed as a treatment.

The medals will be doled out in December, the winners named in the next few days

Stem cells appear to have potential to treat a wide range of illnesses, with a major barrier to the research the ethical implications of obtaining the cells from unborn foetuses.

A busy week in the Swedish capital

This year's laureates in the field of physics will be named on Tuesday, with chemistry following on Wednesday and perhaps the most famous Nobel Peace Prize to be awarded on Friday. As is tradition, there is no set date for the Nobel Prize for Literature - but that will almost certainly fill the gap in the schedule on Thursday. The economics prize winner or winners will be named on October 15.

All the prizes will be awarded in Stockholm simultaneously at a December 10 ceremony.

Stem Cell Discoveries Snag Nobel Prize in Medicine

October 8th, 2012 5:13 pm

Two scientists who discovered the developmental clock could be turned back in mature cells, transforming them into immature cells with the ability to become any tissue in the body pluripotent stem cells are being honored with the Nobel Prize in Physiology or Medicine.

The Nobel Prize honoring Sir John B. Gurdon and Shinya Yamanaka was announced today (Oct. 8) by the Royal Swedish Academy of Sciences.

Th duo's work revealed what scientists had thought impossible. Just after conception, an embryo contains immature cells that can give rise to any cell type such as nerve, muscle and liver cells in the adult organism; these are called pluripotent stem cells, and scientists believed once these stem cells become specialized to carry out a specific body task there was no turning back.

Gurdon, now at the Gurdon Institute in Cambridge, England, found this wasn't the case when in 1962 he replaced the nucleus of a frog's egg cell with the nucleus taken from a mature intestinal cell from a tadpole. And voila, the altered frog egg developed into a tadpole, suggesting the mature nucleus held the instructions needed to become all cells in the frog, as if it were a young unspecialized cell. In fact, later experiments using nuclear transfer have produced cloned mammals. [5 Amazing Stem Cell Discoveries]

Then in 2006, Yamanaka, who was born in 1962 when Gurdon reported his discovery and is now at Kyoto University, genetically reprogrammed mature skin cells in mice to become immature cells able to become any cell in the adult mice, which he named induced pluripotent stem cells (iPS). Scientists can now derive such induced pluripotent stem cells from adult nerve, heart and liver cells, allowing new ways to study diseases.

When Yamanaka received the call from Stockholm about his award, he was doing housework, according to an interview with the Nobel Prize website. "It is a tremendous honor to me," Yamanaka said during that interview.

As for his hopes for mankind with regard to stem cells, he said, "My goal, all my life, is to bring this technology, stem cell technology, to the bedside, to patients, to clinics." He added that the first clinical trials of iPS cells will begin next year.

British scientist John Gurdon told a news conference he still keeps a bad report given to him by his school science teacher

Two pioneers of stem cell research have shared the Nobel prize for medicine or physiology.

John Gurdon from the UK and Shinya Yamanaka from Japan were awarded the prize for changing adult cells into stem cells, which can become any other type of cell in the body.

Prof Gurdon used a gut sample to clone frogs and Prof Yamanaka altered genes to reprogramme cells.

The Nobel committee said they had "revolutionised" science.

The prize is in stark contrast to Prof Gurdon's first foray into science when his biology teacher described his scientific ambitions as "a waste of time".

"I believe Gurdon has ideas about becoming a scientist; on his present showing this is quite ridiculous; if he can't learn simple biological facts he would have no chance of doing the work of a specialist, and it would be a sheer waste of time, both on his part and of those who would have to teach him."

When a sperm fertilises an egg there is just one type of cell. It multiplies and some of the resulting cells become specialised to create all the tissues of the body including nerve and bone and skin.

Stem cell pioneers win Nobel for medicine

October 8th, 2012 5:13 pm

Shinya Yamanaka of Japan and John Gurdon of Britain won the Nobel Prize on Monday for work in cell programming, a frontier that has raised dreams of replacement tissue for people crippled by disease.

The two scientists found that adult cells can be transformed back to an infant state called stem cells, the the key ingredient in the vision of regenerative medicine.

"Their findings have revolutionised our understanding of how cells and organisms develop," the Nobel jury declared. "By reprogramming human cells, scientists have created new opportunities to study diseases and develop methods for diagnosis and therapy."

Among those who acclaimed the award were Britain's Royal Society, Ian Wilmut, "father" of Dolly the cloned sheep, and a leading ethicist, who said it eased a storm about the use of embryonic cells.

Stem cells are precursor cells which differentiate into the various organs of the body.

They have stirred huge excitement, with hopes that they can be coaxed into growing into replacement tissue for victims of Alzheimer's, Parkinson's and other diseases.

Gurdon, 79, said he was grateful but also surprised by the honour, since his main research was done more than 40 years ago.

In 1962, he discovered that the DNA code in the nucleus of an adult frog cell held all the information to develop into every kind of cell.

This meant that an adult cell could in essence be reprogrammed.

His landmark discovery was initially met with scepticism, as the journey from immature to specialised cell was previously deemed irreversible.

Cellerant Awarded SBIR Contract Funding to Develop CLT-009 for Treatment of Thrombocytopenia

October 8th, 2012 5:12 pm

SAN CARLOS, Calif.--(BUSINESS WIRE)--

Cellerant Therapeutics Inc., a biotechnology company developing novel hematopoietic stem cell-based cellular and antibody therapies for blood disorders and cancer, announced today that it has been awarded a Small Business Innovation Research (SBIR) Phase 1 contract and a Phase 2 option from the National Cancer Institute (NCI) valued up to $1,683,503. The SBIR Contract funds the development of CLT-009, a first-in-class, human allogeneic Megakaryocyte Progenitor Cell therapy for the treatment of thrombocytopenia in cancer patients and allows the Company to conduct studies to enable an Investigational New Drug (IND) Application to be filed with the FDA in the next two years.

Thrombocytopenia is characterized as a significant reduction in the concentration of circulating platelets. Platelets are crucial in the process of coagulation to stop bleeding, and thrombocytopenia can increase the risk of severe bleeding in patients. It is becoming an increasingly common problem among oncology patients and a significant dose-limiting toxicity, especially in the treatment of hematological malignancies. Chemotherapy and radiation therapy are the most common causes of thrombocytopenia because the platelet-producing cells, megakaryocytes, and their precursors are highly sensitive to myelosuppressive cytotoxics and ionizing radiation. Thrombocytopenia typically occurs during the initial cycles of high-dose chemotherapy and radiation therapy, usually 614 days after administration. According to Datamonitor, the estimated incidence of cancer patients who suffer from significant chemotherapy-induced thrombocytopenia worldwide was approximately 200,000 in 2008.

Occurrence of severe thrombocytopenia may require dose reductions for chemotherapy regimens which can impact subsequent disease control and survival, especially in the treatment of hematological malignancies such as acute leukemia and high-risk myelodysplastic syndrome. Current treatment options include platelet transfusions which are costly and labor intensive and are associated with risks such as contamination and transmission of viral and bacterial infections. Recombinant human interleukin-11 is the only approved agent for chemotherapy induced thrombocytopenia but its use is limited and has only modest efficacy and significant side effects. CLT-009, a human Megakaryocyte Progenitor Cell product, would be an alternative treatment option, providing the critical megakayocyte progenitor cellular support to rapidly produce platelets in vivo and shorten the duration of severe thrombocytopenia following chemotherapy treatment.

We are delighted to receive this contract from NCI to support the development of our novel, off-the-shelf, platelet product and address a high unmet need, said Ram Mandalam, Ph.D., President and Chief Executive Officer of Cellerant Therapeutics. This contract allows us to not only leverage our experience in developing cellular therapies but also provides us with the ability to bring CLT-009 closer to the clinic. Our unique product portfolio, which now includes CLT-009, along with our CLT-008 myeloid progenitor cell product and our therapeutic antibodies targeting cancer stem cells, demonstrates our continued commitment to developing novel products for the benefit of cancer patients.

In addition to this SBIR contract, Cellerant has previously received grants from the National Institute of Health (NIH) in 2008 2010 to conduct research studies in platelet recovery which it has successfully completed. In its previous studies, Cellerant demonstrated that megakaryocyte progenitor cells were able to produce human platelets in preclinical models with in vivo functionality similar to that of normal human platelets.

This program is funded with Federal funds from the National Institute of Health, Department of Health and Human Services, under Contract No.HHSN261201200076C.

About CLT-009

CLT-009 is a unique, off-the-shelf, cryopreserved, cell-based therapy that contains human Megakaryocyte Progenitor Cells derived from adult hematopoietic stem cells that have the ability to mature into functional platelets in vivo. Cellerant is developing CLT-009 as an effective treatment for chemotherapy and radiation-induced thrombocytopenia in cancer patients.
