MabVax Therapeutics Expands Phase I Clinical Trial Investigation for Patients with Pancreatic Cancer to Include HonorHealth Research Institute

SAN DIEGO, Dec. 5, 2016 /PRNewswire/ -- MabVax Therapeutics Holdings, Inc. (Nasdaq: MBVX), a clinical-stage oncology drug development company, announces the expansion of the Company's MVT-5873 phase I clinical trial to include the HonorHealth Research Institute located in Scottsdale, Arizona. HonorHealth Research Institute is a premier research organization focused on improving the health and well-being of patients.  HonorHealth Research Institute focuses on transitional medicine bridging new cancer treatments from research into clinical development.   HonorHealth Research Institute joins Memorial Sloan Kettering Cancer Center site in New York, and the Sarah Cannon Research Institute sites in Nashville, Tennessee and, Sarasota, Florida as phase I clinical trial sites for MabVax's fully human therapeutic antibody therapy.

The phase I trial is evaluating the safety, tolerability and pharmacokinetics of MVT-5873 as a single agent or in combination with a current standard-of-care chemotherapy regimen in patients with metastatic pancreatic cancer.  The first part of the clinical trial is enrolling patients in a traditional dose escalation regimen to assess safety and determine the recommended phase 2 dose (RP2D) of the antibody. The second part of the clinical trial is enrolling patients to establish the safety and RP2D of MVT-5873 when administered with a standard-of-care chemotherapy.  The lead investigator for the clinical trial at HonorHealth Research Institute is Erkut Borazanci, MD, MS.

"HonorHealth is involved in treating the first individuals with advanced pancreatic cancer with nab-paclitaxel plus gemcitabine and nanoliposomal irinotecan and 5-Fluorouraci," said Erkut Borazanci, MD, a medical oncologist at the HonorHealth Research Institute.   "We have seen tremendous progress in treating pancreatic cancer by using the best scientific insights and bringing them directly to patients. We are excited to be partnering with MabVax Therapeutics on such an important clinical trial."

"We are very excited to engage with HonorHealth's world-class clinical research organization and are looking forward to drawing upon the organization's extensive expertise in the development of new therapeutic agents particularly for patients with advanced pancreatic cancer," said David Hansen, MabVax President and CEO. "The addition of HonorHealth Research Institute comes as we are expanding our phase I trial to treat patients newly diagnosed with pancreatic cancer with MVT-5873 in combination with chemotherapy. Pancreatic cancer is very difficult to treat and patients with advanced disease have few therapeutic options.  We are delighted to be working with researchers at HonorHealth to evaluate MVT-5873 as a potential new therapeutic option for these patients."

About MVT-5873:

MabVax's MVT-5873 is a fully human antibody discovered from the immune response of cancer patients vaccinated with an antigen-specific vaccine during a Phase I trial at Memorial Sloan Kettering Cancer Center.  In preclinical research, the antibody has demonstrated high specificity and affinity, and has shown potent cancer cell killing capacity and efficacy in animal models of pancreatic, colon and small cell lung cancers.  The antigen the antibody targets is expressed on more than 90% of pancreatic cancers making the antibody potentially broadly applicable to most patients suffering from this type of cancer.
