Cellect Biotechnology and Washington University (WU) Finalize Accelerated Clinical Trial Agreement

TEL AVIV, Israel and ST. LOUIS, Missouri, July 8, 2019 /PRNewswire/ -- As the two organizations move closer to the commencement of the clinical trial to determine the safety and tolerability of the Apograft technology for bone marrow transplantations, Cellect Biotechnology Ltd. (Nasdaq: APOP), and Washington University (WU), a leading academic institution based in St. Louis, MO, announced the signing of an Accelerated Clinical Trial Agreement (CTA). Cellect has successfully completed the technology transfer to WU's facility, and results of the in-vivo portion of the toxicology study have shown no signs or symptoms of toxicity.

"We are continuing to advance our lead development program, ApoGraft™, and pleased to achieve this milestone with Washington University," commented Dr. Shai Yarkoni, Chief Executive Officer. "We have had ongoing and positive discussions with the U.S. Food and Drug Administration (FDA), and based on its feedback we can bypass further pre-Investigation New Drug (IND) interactions and proceed directly to IND filing. Therefore, our immediate next step is to complete our IND application and submit it to the FDA during the third quarter, and our objective remains to commence treatment of U.S. patients during the first half of 2020."

"The importance of this trial cannot be underestimated, as finding a suitable donor remains a constant challenge for patients in need of an urgent Hematopoietic stem cell transplantation (HSCT)," added Dr. Yarkoni. "It is well known that the ability to obtain half-matched stem cells from a first degree relative represents a significant breakthrough in the field. However, while Haploidentical (haplo) HSCT is characterized by the nearly uniform and immediate availability of a donor, it has a high risk of graft-versus-host disease (GVHD) and tentative poor immune reconstitution when GVHD is prevented by all existing methods of rigorous ex vivo or in vivo T-cell depletion. As such, the current treatment paradigm is based on chemotherapy post-transplant, which by itself harbors significant morbidity. Our technology is specifically aimed at improving today's standard of care with a safer pre-transplantation procedure that will be of far greater benefit to patients.

"The Company's platform technology, ApoGraft™, is based on findings that GVHD can be prevented by Fas ligand mediated selective depletion of GvHD causing subpopulation of immune mature cells. The combination of haplo-HSCT with the ApoGraft™ process has the potential to improve the safety profile of haplo-HSCT by preventing GVHD without adversely affecting GVL or engraftment," concluded Dr. Yarkoni.

Upcoming Clinical Program Objectives

U.S. ApoGraft02 Study

• Approval of Scientific Advisory Board Expected by mid-third quarter of 2019
• Submit IND application with the FDA by the end of third quarter of 2019
• Upon FDA acceptance of the Company's IND application, together with its collaboration partner, Washington University, begin treating U.S. patients in the first half of 2020

Israel ApoGraft01 Study

• Complete recruitment by the end of 2019 and release data by the end of the first half of 2020

The Principal Investigator for the clinical trial is Zhifu Xiang, M.D., of Washington University. He is an Associate Professor in the Division of Oncology's Bone Marrow Transplantation & Leukemia Section in the Department of Medicine. In addition, John Dipersio M.D, Ph.D., will act as co-Principal Investigator for the study. He is the chief of the Division of Oncology in the Department of Medicine at Washington University. The collaboration is led by Dr. DiPersio, who also is Director of the Center for Gene and Cellular Immunotherapy, Washington University School of Medicine, and President of the American Society for Blood and Marrow Transplantation. The primary endpoint of the study is overall incidence, frequency and severity of adverse events related to ApoGraft™ at one year post-transplantation.

Washington University School of Medicine in St. Louis is among the leading medical centers in the U.S. This is Cellect's first collaboration with a U.S. site for clinical development following the establishment of the clinical advisory committee consisting of Prof Negrin of Stanford, Dr. Cutler of Harvard Medical School and Professor Rowe of Northwestern University. Cellect's ApoGraft™ is currently being evaluated outside of the U.S. in a Phase I/II clinical trial to evaluate the safety and tolerability of functionally selected donor derived mobilized peripheral blood cells that undergo the ApoGraft process in patients suffering from hematological malignancies that are undergoing allogeneic HSCT.
