SOUTH SAN FRANCISCO, Calif., March 02, 2017 (GLOBE NEWSWIRE) -- CytomX Therapeutics, Inc. (Nasdaq:CTMX), a biopharmaceutical company developing investigational Probody™ therapeutics for the treatment of cancer, today reported full-year 2016 financial results.

As of December 31, 2016, CytomX had cash and cash equivalents and short-term investments of $181.9 million. Based upon its current operating plan, the Company expects its existing capital resources will be sufficient to fund operations into 2019.

CX-2009 (CD166 Probody Drug Conjugate) Program

• Following completion of GMP manufacturing and GLP toxicity studies in 2016, the IND filing for CX-2009 remains on track for the first half of 2017.
• CX-2009 is a first-in-class Probody drug conjugate targeting the highly expressed tumor antigen, CD166.

Full-Year Financial Results
Cash, cash equivalents and investments totaled $181.9 million as of December 31, 2016, compared to $186.7 million as of December 31, 2015. The decrease reflects cash used in operations, partially offset by a $30 million upfront payment received from AbbVie in connection with the development and collaboration agreements entered into in April 2016, and $25 million in milestone payments received from Bristol-Myers Squibb in connection with its third target selection in January 2016, and fourth target selection in December 2016.

Research and development expenses were $54.8 million for the year ended December 31, 2016, compared to $28.4 million for the year ended December 31, 2015. The increase was primarily attributable to $9.6 million in manufacturing costs for the Company’s CX-072, CX-2009 and CX-2029 programs, $4.5 million in laboratory and professional services and supplies, $3.1 million in personnel-related expenses due to an increase in headcount, $3.1 million in non-cash stock-based compensation due to higher stock valuation, $2.4 million to advance CX-072 into Phase 1/2 clinical development, $1.7 million in royalty payments triggered by the payments from Bristol-Myers Squibb’s third and fourth target selections, clinical candidate selection, as well as upfront payments from AbbVie, and $1.6 million in facilities-related expenses due to a move to a larger facility in October 2016.

General and administrative expenses were $19.9 million for the year ended December 31, 2016, compared to $12.6 million for the year ended December 31, 2015. The increase was predominantly due to $3.2 million in non-cash stock based compensation due to higher stock valuation, $2 million in professional service and outside service expenses, $1.8 million in personnel-related expenses due to an increase in headcount and $0.4 million in facilities-related expense due to a move to a larger facility in October 2016.

About CytomX Therapeutics
CytomX is a clinical-stage, oncology-focused biopharmaceutical company pioneering a novel class of investigational antibody therapeutics based on its Probody technology platform. The Company uses its platform to create proprietary cancer immunotherapies against clinically-validated targets, such as PD-L1, and develop first-in-class cancer therapeutics against difficult-to-drug targets, such as CD166. Probody therapeutics are designed to take advantage of unique conditions in the tumor microenvironment to enhance the tumor-targeting features of an antibody and reduce drug activity in healthy tissues. The Company’s lead program, CX-072, a wholly-owned PD-L1-targeting Probody therapeutic, is being evaluated in a Phase 1/2 study. The Investigational New Drug filing for CX-2009 is slated for the first half of 2017. CX-2009 is a first-in-class Probody drug conjugate targeting the highly expressed tumor antigen, CD166. Both clinical trials are modules within PROCLAIM (Probody Clinical Assessment In Man), an international umbrella clinical trial program that provides clinical trial sites with access to the company’s novel therapies under one central protocol. In addition to its proprietary programs, CytomX is collaborating with strategic partners including AbbVie, Bristol-Myers Squibb Company, Pfizer Inc., MD Anderson Cancer Center and ImmunoGen, Inc.
