SOUTH SAN FRANCISCO, Calif., Dec. 12, 2016 (GLOBE NEWSWIRE) -- Calithera Biosciences, Inc. (Nasdaq:CALA), a clinical stage biotechnology company focused on the development of novel cancer therapeutics, announced that William D. Waddill has resigned as the company’s Senior Vice President and Chief Financial Officer due to his relocation outside Northern California.  Mr. Waddill’s resignation will be effective on or about December 31, 2016 in order to facilitate a smooth transition.  

“On behalf of everyone at Calithera, I thank Will for his numerous contributions to our company during his tenure, including most notably his management of our 2014 initial public offering.  Will’s leadership has helped Calithera to build a clinical pipeline of novel cancer therapies targeting tumor and immune cell metabolism.  We wish Will the very best in future endeavors,” said Susan Molineaux, PhD, President and Chief Executive Officer of Calithera.

The company also announced the recent promotions of Curtis Hecht to Senior Vice President, Business and Corporate Development, and Jennifer McNealey to Vice President, Investor Relations and Strategy.  Mr. Hecht joined Calithera in April 2014, and has worked in the biopharmaceutical industry for over 20 years. Most recently he served as Vice President of Business Development at inVentiv Health.  He also served as a partner of DNA Ink, and managed the Roche-Genentech joint development and operations committee.  Ms. McNealey joined Calithera in February 2015.  Before joining Calithera, Ms. McNealey served as an investor relations advisor to biotechnology companies.  She also founded Laurient, an independent research firm, and prior to that she served as a biotech analyst and portfolio manager.

“These promotions reflect the leadership role these key individuals have played in developing Calithera Biosciences into a fully integrated biotechnology company,” said Susan Molineaux.

Following Mr. Waddill’s departure, Susan Molineaux will become the company’s Principal Financial Officer and assume Mr. Waddill’s administrative responsibilities, and Stephanie Wong, the company’s Vice President Finance since April 2014, will become the company’s Principal Accounting Officer.  “With these changes and the increased responsibilities that Jennifer will be taking on in managing investor relations and that Curtis will be taking on in corporate development, the company is well positioned to move forward with a strong leadership team,” said Susan Molineaux.

About Calithera Biosciences

Calithera Biosciences, Inc. is a clinical-stage pharmaceutical company focused on discovering and developing novel small molecule drugs directed against tumor metabolism and tumor immunology targets for the treatment of cancer.  Calithera’s lead product candidate, CB-839, is a potent, selective, reversible and orally bioavailable inhibitor of glutaminase.
