On January 15, 2019 Orion Biotechnology Canada Ltd., a developer of novel medical treatments, reported preclinical data produced in collaboration with Charles River Laboratories, evaluating the efficacy of OB-002O (5P12-RANTES) in colorectal cancer (Press release, Orion Biotechnology, JAN 15, 2019, View Source [SID1234532673]). BALB/c mice were inoculated subcutaneously with the CT-26 colorectal cancer cell line. Three days after inoculation intraperitoneal treatment was started with OB-002O, a murine anti-PD-1 antibody, OB-002 + anti-PD-1, or saline placebo. Treatment was given daily or every third day. Treatment with OB-0020 alone led to statistically significant delayed tumor growth at multiple time-points. An even more profound effect on the decrease in mean tumor volume was observed in combination cohort where animals received both, OB-0020 and the anti-PD-1 antibody (p>0.05).

"There is growing awareness of the role of CCR5 antagonism as an important component of cancer immunotherapy. OB-002O is an extremely potent CCR5 antagonist and we are delighted to see that OB-002O has robust efficacy alone and in combination with an anti-PD-1 antibody in the CT-26 colorectal cancer model. These data support the further preclinical and clinical development of OB-002O for colorectal cancer" said Dr. Ian McGowan, Chief Scientific Officer for Orion Biotechnology.

Mark Groper, President and CEO of Orion Biotechnology added; "We are delighted by these preliminary data and look forward to the later stage development of OB-002O in colorectal cancer as well as exploring the efficacy of OB-002O in other cancer models."

On January 15, 2019 Kitov Pharma (NASDAQ/TASE: KTOV), an innovative pharmaceutical company, reported new findings from its ongoing collaboration with researchers from the Hebrew University of Jerusalem (Press release, Kitov Pharmaceuticals , JAN 15, 2019, View Source [SID1234532669]). The data reveal NT219’s high affinity and selective binding to its target proteins.

Hadas Reuveni, Ph.D., Chief Technology Officer at Kitov’s subsidiary, TyrNovo Ltd., in collaboration with Dr. Galia Blum and Dr. Ofra Moshel from the Hebrew University demonstrated that NT219 binds directly to Insulin Receptor Substrates (IRS) 1/2 and to the Signal Transducer and Activator of Transcription 3 (STAT3), both known modulators of tumor survival, metastasis and drug resistance. Data showed that a short exposure of cancerous cells to NT219 was sufficient to trigger irreversible shutdown of these pathways, resulting in a long-term anti-cancer effect.

Based on these latest findings, Kitov and Yissum, the Technology Transfer company of the Hebrew University of Jerusalem, have extended their collaboration agreement in order to deepen the understanding of NT219’s efficacy in overcoming tumors’ resistance to immunotherapy.

As previously reported (Reuveni et al, Cancer Research, 2013) upon binding to IRS1/2 a three-step mechanism is activated. IRS1/2 dissociates from the cell membrane, undergoes serine phosphorylation which prevents rebinding to the receptor, and is finally degraded by the proteasome. This sequence of events leads to the blockage of AKT – a major cancer cell survival pathway.

"We are excited about the new data which demonstrate NT219’s unique mechanism of action. NT219, a new and promising concept in cancer therapy, is designed to prevent, reverse, and delay resistance to anti-cancer drugs. We are developing NT219 as a drug to be used in combination with other therapies that has a potential to overcome cancer drug resistance and to boost the efficacy of numerous oncology drugs on the market today," stated Kitov CEO, Isaac Israel.

About NT219

NT219 is a small molecule that presents a new concept in cancer therapy by promoting the degradation and inhibiting the phosphorylation of two oncology-related signal transducers, Insulin Receptor Substrates (IRS) 1/2 and signal transducer and activator of transcription 3 (STAT3), respectively. While targeted anti-cancer drugs inhibit the "ON" signal, NT219 activates the "OFF" switch, extensively blocking major oncogenic pathways. In pre-clinical trials, NT219, in combination with several approved cancer drugs, displayed potent anti-tumor effects and increased survival in various cancers, including sarcoma, melanoma, pancreatic, lung, head & neck, prostate and colon cancers, by preventing the tumors from developing drug resistance and reversing resistance after it had been acquired. NT219 is licensed from Yissum, the technology transfer company of the Hebrew University of Jerusalem

On January 15, 2019 Marker Therapeutics, Inc. (Nasdaq:MRKR), a clinical-stage immuno-oncology company specializing in the development of next-generation T cell-based immunotherapies for the treatment of hematological malignancies and solid tumor indications, reported that data from four abstracts—including three oral presentations—were accepted for presentation at the Transplantation & Cellular Therapy (TCT) Meetings of the American Society for Blood and Marrow Transplantation and the Center for International Blood and Marrow Transplant Research (ASBMT and CIBMTR) (Press release, TapImmune, JAN 15, 2019, View Source [SID1234532667]). The studies summarize data achieved using multi-tumor antigen specific T cells that were developed at Baylor College of Medicine in the laboratories of Dr. Swati Naik, Dr. Ann Leen, and Dr. Premal Lulla, and exclusively licensed to Marker.

"Steve is the right leader for Onconova at this time. He has been instrumental to the Company’s progress thus far and his proven track record in drug development will continue to serve the Company well as it advances the Phase 3-stage rigosertib programs toward approval and commercialization. The Board thanks Ramesh for his leadership and contributions to Onconova, and for positioning Onconova to reach critical upcoming milestones. We view Steve, and the recently expanded executive team that he has assembled, as poised to achieve clinical progress and business development objectives," said Michael Hoffman, Chairman of the Onconova Board of Directors.

Dr. Fruchtman has extensive industry experience in clinical research in MDS, hematologic malignancies, and solid tumors. He served with increasing leadership responsibilities at Ortho Biotech, Novartis, and biotechnology companies leading to successful clinical trial completion and regulatory approvals for a number of new chemical entities in various malignancies. Prior to his transition to industry, Steve served as the Director of the Myeloproliferative Disorder Program at The Mount Sinai Hospital in New York City, a Center of Excellence, and established the Stem Cell Transplant Program there. His commitment to the areas of hematology/oncology and myeloproliferative disorders is exemplified by his service as an external reviewer for prestigious journals such as the New England Journal of Medicine, Mayo Clinic Proceedings, Experimental Hematology, and others. He received his Bachelor of Arts with Honors from Cornell University, and his M.D. from New York Medical College. He was recently named to the Board of The Bone Marrow Foundation. Dr. Fruchtman commented, "I am very grateful to the Board for this honor. I thank Ramesh for his mentorship during my tenure as President and Chief Medical Officer. My colleagues at Onconova and I are focused on achieving our milestones. The global INSPIRE trial for rigosertib in MDS has the potential to offer a novel treatment option for these patients. We are very excited about the anticipated full enrollment of the INSPIRE trial in the second half of 2019, the advancement to Phase 3 of the oral rigosertib combination trial, and the studies of rigosertib in pediatric RASopathies and other unmet medical needs. I firmly believe that rigosertib has the potential to support multiple indications in different areas of oncology. In addition, our innovative CDK 4/6 inhibitor, ON 123300, is in advanced pre-IND stage, and is expected to enter the clinic during the first half of the year. This vision presents opportunities to enhance the value of the Company in the coming years."
