SAN DIEGO, Aug. 31, 2015 /PRNewswire/ -- MabVax Therapeutics Holdings, Inc. (OTCQB: MBVX) aclinical stage oncology drug development company announces that the Company's lead antibody, HuMab 5B1, will be garnering major attention as the subject of five separate presentations during the upcoming World Molecular Imaging Congress (WMIC) being held in Hawaii September 2-5, 2015. Researchers from the Department of Radiology at Memorial Sloan Kettering Cancer Center (MSK) will present results on the use of MabVax's lead antibody as a PET imaging agent and as a radioimmunotherapy agent targeting pancreatic cancer.
Presenters at the WMIC include Jacob Houghton, Ph.D. of MSK, who will present results from two preclinical in vivo studies using the HuMab 5B1 antibody as an ImmunoPET imaging agent in the context of circulating antigen as well as new pretargeted methods for the immunoPET imaging of CA19.9 in murine models of pancreatic cancer. Dalya Abdel-Atti will present the results of using HuMab5B1 in ImmunoPET imaging with newly developed murine organoid models of pancreatic cancer. A third presenter, Jan-Philip Meyer, Ph.D., will present results of using HuMab 5B1 as a pre-targeting agent followed by administration of the short-lived (18F)-NOTA-labeled tetrazine radioligand for PET imaging and in vivo coupling, examining the efficiency of HuMab5B1 in imaging and the reduction in exposure to the radiolabel. All four presentations illustrate the potential utility of the antibody as a next generation imaging agent for pancreatic cancer. Lastly, Ryan Lanning, M.D. Ph.D., will present the results of using HuMab 5B1 as a radioimmunotherapy agent for treatment of pancreatic cancer.
Because five-year survival rates in pancreatic cancer are only 5% and more than half of all patients initially diagnosed already have metastatic disease, the difficulties in identifying distant metastases that often go undetected as well as developing advanced therapeutics to treat this difficult cancer are significant unmet medical needs. These researchers at MSK are on the cutting edge of this technology and may well help develop a new generation of diagnostic and therapeutic agents using HuMab 5B1. Continuing studies of HuMab 5B1 could further demonstrate the utility of a broad technology platform useful both as a imaging and therapeutic agent.
About HuMab 5B1
The fully human antibody HuMab 5B1 was recovered from patients undergoing cancer vaccine treatment at Memorial Sloan-Kettering Cancer Center. The HuMab 5B1 has demonstrated high specificity, affinity, and lack of cross-reactivity with similar antigens. The antibody has also shown potent cancer cell killing capacity and efficacy in animal models of pancreatic, colon, and small cell lung cancers. Ongoing toxicology results continue to demonstrate an acceptable profile in acute and repeat dose studies in animals. MabVax plans to initiate two complementary Phase I clinical trials in the first quarter of 2016. One clinical trial is aimed at determining the safety and potential utility of HuMab 5B1 as a therapeutic agent in subjects with metastatic pancreatic cancer. The second clinical trial is aimed at demonstrating the utility of 89Zr-HuMab 5B1, the Company's radio-labeled HuMab 5B1 antibody, as a next-generation PET imaging agent for the diagnosis, staging, and management of pancreatic cancer.
MabVax Therapeutics Holdings, Inc. is a clinical stage biotechnology company focused on the development of vaccine and antibody based therapies to address unmet medical needs in the treatment of cancer. MabVax has discovered a pipeline of human monoclonal antibody products based on the protective immune responses generated by patients who have been immunized against targeted cancers with the Company's proprietary vaccines. MabVax has the exclusive license to the therapeutic vaccines from Memorial Sloan Kettering Cancer Center. MabVax has two cancer vaccines targeting recurrent sarcoma and ovarian cancer in proof of concept Phase II multi-center clinical trials, and a vaccine targeting neuroblastoma ready for Phase II clinical development.
