MabVax Therapeutics Announces Closing of Financing

SAN DIEGO, April 6, 2015 /PRNewswire/ -- MabVax Therapeutics Holdings, Inc. (OTCQB: MBVX) ("MabVax" or "Company"), a clinical-stage cancer immunotherapy company, is pleased to announce that it has closed on gross proceeds of approximately $11.6 million in a private placement (the "Private Placement") led by OPKO Health, Inc. (NYSE: OPK) and Dr. Phillip Frost, CEO and Chairman of OPKO Health. 

Pursuant to the Private Placement, MabVax issued a total of 15,486,001 units at $0.75 per unit (the "Unit") for total gross proceeds of $11,614,501 before issuance costs of approximately $500,000.  Each Unit consists of one share of common stock and a 30-month warrant to purchase one-half of one share of common stock (the "Warrant").   The Warrants are exercisable at $1.50 per each whole share of common stock.  Laidlaw & Company (UK) Ltd. acted as an advisor on the transaction. 

Of the Units sold, approximately $6 million (including the funds provided by OPKO) will be held in escrow pending approval of certain matters to be submitted to stockholders for approval, including certain changes to the Board of Directors acceptable to one of the leading investors.  Escrowed funds will be required to be returned to investors in the event that the conditions have not been met within 60 days of closing.

Commenting on the announcement, Dr. Phillip Frost, CEO and Chairman of OPKO Health, Inc., stated, "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."

"This financing will provide MabVax with funds to advance our pipeline of clinical products through several key milestones, and allow us to pursue additional preclinical  research programs in our pipeline of which several are partnered with Memorial Sloan Kettering Cancer Center," commented David Hansen, President and CEO of MabVax.  "We are proud to have OPKO Health and biotech investor and entrepreneur, Dr. Phillip Frost, lead the financing.  Their input will be invaluable as MabVax advances its business plan."   

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. 

In addition, MabVax currently has advanced Phase II trials ongoing for its recurrent sarcoma and ovarian cancer vaccines, and patient survival results are expected in the first half of 2016.  These Phase II vaccine programs have received significant funding from the National Institute of Health (NIH). 

The Company also has a Phase II-ready therapeutic vaccine for childhood neuroblastoma, which has been granted orphan drug designation by the FDA.

In conjunction with the Private Placement, Steven Rubin will be joining the advisory board of MabVax.  Mr. Rubin is Executive Vice President and Director at OPKO Health, and serves on the Board of Directors of Cocrystal Pharma and Neovasc, Inc.
