MabVax Therapeutics Holdings, Inc. Provides Corporate Update and Reports First Quarter 2015 Financial Results

SAN DIEGO, CA--(Marketwired - May 15, 2015) - MabVax Therapeutics Holdings, Inc. (OTCQB: MBVX), a clinical stage oncology drug development company, provided today a corporate update and reported financial results for the first quarter ended March 31, 2015.

"We have made outstanding progress since the beginning of the year in both our drug development initiatives as well as in capital formation," stated MabVax's President and Chief Executive Officer David Hansen. "Most important was the completion of an $11.7 million equity financing led by OPKO Health, Inc. (OPK) and biotech investor and entrepreneur Dr. Phillip Frost, Chairman and CEO of OPKO Health. We are proud to have OPKO Health and Dr. Frost, lead the financing. Their input will be invaluable as MabVax advances its business plan. As a result of the financing, we believe we have sufficient capital to advance the planned Phase I clinical trial of our HuMab 5B1 antibody to the point of determining if we have an early indication of safety."

The clinical development plan for HuMab 5B1 calls for two Phase I clinical trials to begin late this year. One program will determine the safety and potential utility of HuMab 5B1 in subjects with metastatic pancreatic cancer as a single agent or in combination with the current standard of care. The second program will be aimed at demonstrating the utility of 89Zr-HuMab 5B1, our radiolabeled HuMab 5B1 antibody, as a next generation PET imaging agent for the diagnosis and management of pancreatic cancer.

Hansen continued, "We recently announced encouraging non-human primate safety data for HuMab 5B1 which further supports our plan of launching Phase 1 clinical trials by year-end. We also have initiated GMP manufacturing of our clinical materials for both upcoming Phase 1 clinical trials of 5B1."

Recent Corporate Milestones

Significant financing transaction with a leading investor -- On April 10, 2015, the Company closed on approximately $11.7 million in a private placement led by OPKO Health, Inc. (NYSE: OPK) and Dr. Phillip Frost, CEO and Chairman of OPKO Health, who commented, "The target for MabVax's first novel human antibody addresses important medical problems in need of better therapeutic solutions. The early data for its HuMab 5B1 antibody are encouraging and MabVax has a pipeline of dozens of novel antibody leads on its discovery platform from which it may select promising candidates to develop through clinical trials."

MabVax intends to use the proceeds from the financing to initiate Phase 1 trials for its HuMab 5B1 antibody later this year and to further advance other novel human antibodies in its pipeline. The HuMab 5B1 antibody is being developed as both a diagnostic and therapeutic product targeting pancreatic and colon cancer.

Encouraging results of non-human primate toxicology study -- On May 5, 2015, the Company received the final report on toxicology testing of its HuMab 5B1 antibody, which was completed by a leading independent contract research organization. The report detailed that the antibody, given in either a single dose or repeated doses, had no significant adverse findings even at the highest dosage levels tested. These results further validate the Company's decision to advance HuMab 5B1 into Phase 1 clinical trials before the end of 2015. Non-human primates in this acute dose range finding study were challenged with multiple dose levels to assess drug pharmacokinetics, as well as with repeated doses of the antibody to identify any adverse toxicology signals. These studies were conducted in the most relevant animal models with material produced by our GMP manufacturing partner. The antibody as tested is representative of the clinical supply material scheduled for delivery later this year.

About HuMab 5B1:
In pre-clinical research, MabVax's HuMab 5B1 antibody has demonstrated high specificity, affinity, and lack of cross-reactivity with closely related antigens. The antibody has also shown potent cancer cell killing capacity and efficacy in animal models of pancreatic, colon, and small cell lung cancer. When combined with a radio-label as a novel PET imaging agent, 89Zr-HuMab 5B1 has demonstrated high image resolution of tumors in established xenograft animal models, making it attractive as a potential companion diagnostic for the therapeutic product.

The clinical development plan calls for two Phase 1 clinical trials to begin late this year. One program will determine the safety and potential utility of HuMab 5B1 in subjects with metastatic pancreatic cancer as a single agent or in combination with the current standard of care. The second program will be aimed at demonstrating the utility of 89Zr-HuMab 5B1, our radiolabeled HuMab 5B1 antibody, as a next generation PET imaging agent for the diagnosis and management of pancreatic cancer.
