Calithera Biosciences, Inc. To Present Data On CB-839 At The American Association for Cancer Research Annual Meeting 2014

SOUTH SAN FRANCISCO, Calif., April 1, 2014 /PRNewswire/ -- Calithera Biosciences, a biotechnology company focused on the development of novel cancer therapeutics, today announced the presentation of data for its lead clinical candidate, CB-839, at the American Association for Cancer Research (AACR) Annual Meeting 2014, to be held in San Diego, CA, April 5-9, 2014. CB-839 is a potent and selective orally bioavailable glutaminase inhibitor that blocks the growth and survival of many different types of cancer cells by interfering with their metabolism of glutamine.

During a minisymposium session on cancer metabolism, Calithera will report on the development of novel pharmacodynamic assays that will be applied to the company's clinical studies to measure glutaminase inhibition in patients following administration of CB-839. Calithera researchers will also present preclinical data in a poster detailing CB-839's antiproliferative activity in a range of solid and hematologic tumor types:
