Yissum Research Development Company of the Hebrew University of Jerusalem has signed an exclusive world-wide licensing and research agreement with BioTheryX, Inc., developer of novel protein degradation and immunomodulatory drugs for cancer and immune dysfunction, for the development and commercialisation of drug candidates representing first-in-class therapy for both hematologic and solid malignancies. Financial terms of the license were not disclosed.
The novel technology was invented by Yinon Ben-Neriah, MD, PhD, Blumenthal Professor of Cancer Research, Lautenberg Center for Immunology, Hebrew University-Hadassah Medical School, with generous support by AMRF (The Dr. Miriam and Sheldon G. Adelson Medical Research Foundation). Dr. Ben-Neriah’s and his team showed that inhibition of the clinically validated enzyme CKI-alpha, induces several tumor suppressor pathways, including a new type of DNA damage response and p53 activation. This provides a novel approach to treat a wide range of cancers, in particular selective types of hematological malignancies.
Prof. Yinon Ben-Neriah has recently received the 2016 Rappaport Prize for excellence in biomedical research, among others, for his ground breaking research on the relationship between chronic inflammation and cancer and the treatment of leukemia.
Based on their complementing expertise, BioTheryX and Yissum have agreed to join forces and focus on the selection and advancement of clinical candidates designed to inhibit CKI-alpha. Initial clinical focus for these candidates will be selective subtypes of myelodysplastic syndrome and acute myeloid leukemia that are not responsive to available cancer therapy.
In preclinical studies of acute leukemia, these clinical candidates showed a far greater therapeutic potential than any previously reported studies. Treatment of genetically-modified leukemic mice modeling poor-prognosis human acute myeloid leukemia, abolished the disease signs in the majority of the animals, without compromising the normal bone marrow, demonstrating that CKI-alpha inhibitors have a large therapeutic window and are unique in their capacity to specifically eliminate leukemia stem cells, including otherwise treatment-resistant stem cells - a strong indication of cancer cure.
Yaacov Michlin, president and chief executive officer, Yissum, commented, “The treatment that was developed in Prof. Ben-Neriah’s lab is very different from other available therapies, both in its mechanism of action and its ability to eliminate leukemic stem cells, and thus in its therapeutic potential. In light of the successful pre-clinical studies, we believe that it offers a significant breakthrough, and we are very pleased to partner with BioTheryX in the development of new drug candidates for potential treatment of a variety of hematological indications. We believe that the combined know-how and research efforts of the teams at BioTheryX and the Hebrew University will facilitate new drug development, leading to significant advancement in the therapy of this class of devastating cancer diseases.”
David Stirling, chief executive officer, BioTheryX, commented, “BioTheryX is particularly pleased to partner with the Hebrew University on this important project. Our team, having developed the remarkable IMiD family of drugs while at Celgene, which have improved the quality of life of so many cancer patients and their loved ones, brings a deep wealth of experience to developing novel cancer therapies that modulate protein degradation and the immune system to target cancer causing proteins for destruction. We believe that these unique drug candidates from the Hebrew University will not only bring new treatment modalities to a variety of hematological cancers, but may provide the only option for those patients that relapse and become resistant to currently available therapies.”
