WALTHAM, Mass., Oct. 01, 2018 (GLOBE NEWSWIRE) -- TESARO, Inc. (NASDAQ: TSRO), an oncology-focused biopharmaceutical company, today announced that data from a total of five abstracts will be presented at the Society for Immunotherapy of Cancer (SITC) Annual Meeting from November 7-11, 2018 in Washington, D.C.

“At this year’s SITC Annual Meeting, we are excited that several abstracts will be presented highlighting data from our rapidly advancing immuno-oncology portfolio, including an oral presentation of the first clinical data of TSR-022, our anti-TIM-3 antibody, in combination with TSR-042, our anti-PD-1 antibody,” said Mary Lynne Hedley, Ph.D., President and COO of TESARO. “In addition, data from the GARNET trial of TSR-042 in recurrent non-small cell lung cancer (NSCLC) patients will be featured in a poster presentation. TSR-042 is the foundation of our lung cancer strategy and provides a strategic advantage for TESARO in further developing niraparib, TSR-022, and TSR-033, our anti-LAG-3 antibody.”

About TSR-042, TSR-022, and TSR-033

TSR-042 is an investigational humanized anti-programmed death (PD)-1 monoclonal antibody that binds with high affinity to the PD-1 receptor and effectively blocks its interaction with the ligands PD-L1 and PD-L2. TSR-042 is the only anti-PD-1 therapy being studied as monotherapy every 3 weeks for 4 doses then every 6 weeks thereafter. TSR-042 was developed as part of the collaboration between TESARO and AnaptysBio, Inc. This collaboration was initiated in March of 2014, and is focused on the development of monospecific antibody drugs targeting PD-1, TIM-3 (TSR-022), and LAG-3 (TSR-033), in addition to a bi-specific antibody drug candidate targeting PD-1/LAG-3 (TSR-075).
