TESARO Announces Data Presentations at the ESMO 2018 Congress

WALTHAM, Mass., Oct. 09, 2018 (GLOBE NEWSWIRE) -- TESARO, Inc. (NASDAQ: TSRO), an oncology-focused biopharmaceutical company, today announced that data from six abstracts will be presented at the European Society for Medical Oncology (ESMO) Congress from October 19-23, 2018 in Munich, Germany.

“At this year’s ESMO Congress, blinded, pooled interim safety data from PRIMA will be presented, which demonstrated that an individualized starting dose of ZEJULA resulted in a favorable tolerability profile compared to a fixed starting dose of 300 milligrams. PRIMA is a fully-enrolled Phase 3 trial for patients with first-line ovarian cancer regardless of biomarker status and we expect top-line results to be available in late 2019,” said Mary Lynne Hedley, Ph.D., President and COO of TESARO. “TESARO is also advancing a robust immuno-oncology portfolio. Data will be presented in a poster discussion from the MSI-H endometrial cohort of the GARNET trial of TSR-042, our anti-PD-1 antibody, for which we are planning to submit a biologic license application (BLA) next year.”

Please plan to visit TESARO at Booth #212 for information about ZEJULA and our pipeline.

Details of TESARO’s poster presentations are as follows (all times local):
All posters will be on display beginning Saturday, October 20, 7:30 AM.

About ZEJULA (Niraparib)
ZEJULA (niraparib) is a poly (ADP-ribose) polymerase (PARP) inhibitor indicated for the maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in a complete or partial response to platinum-based chemotherapy. In preclinical studies, ZEJULA concentrates in the tumor relative to plasma, delivering greater than 90% durable inhibition of PARP 1/2 and a persistent antitumor effect. Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML), including some fatal cases, was reported in patients treated with ZEJULA. Discontinue ZEJULA if MDS/AML is confirmed.  Hematologic adverse reactions (thrombocytopenia, anemia and neutropenia), as well as cardiovascular effects (hypertension and hypertensive crisis) have been reported in patients treated with ZEJULA. Monitor complete blood counts to detect hematologic adverse reactions, as well as to detect cardiovascular disorders, during treatment.  ZEJULA can cause fetal harm and females of reproductive potential should use effective contraception. Please see full U.S. prescribing information, including additional important safety information, available at www.zejula.com.
