TSRO Climbs On Clinical Update

As mentioned above, TESARO is having an incredibly strong day in the market today after providing a clinical update. In a press release issued early this morning the company announced that it has initiated the second stage of the JASPER study. TSRO designed the JASPER study to assess the clinical benefit of ZEJULA® in combination with an anti-PD-1 antibody in first-line non-small cell lung cancer (NSCLC) patients.

In the release, the company said that the decision to advance the trial was based on the trial achieving the protocol defined response criteria in the initial cohort of 16 treated patients with PD-L1 expressions. Of the 16 patients, 14 were evaluable for a response. The company said that 9 of the 14 patients had objective responses by RECIST criteria at the time of the analysis and that all 14 patients saw a reduction in tumor burden. In a statement, Mary Lynne Hedley, Ph.D., President and COO of TSRO, had the following to offer:




These JASPER data provide preliminary evidence that the combination of ZEJULA and an anti-PD-1 antibody could be active as a first-line treatment for patients with non-small cell lung cancer and high levels of PD-L1 expression… In the second stage of the trial, 36 additional patients will be enrolled and treated with ZEJULA in combination with TSR-042, our anti-PD-1 antibody. TSR-042 is the foundation of our lung cancer strategy, and is also being studied as a monotherapy in our GARNET trial in anti-PD-(L)1 naïve patients who have progressed on chemotherapy, and in combination with TSR-022, our anti-TIM-3 antibody, in AMBER, a study in late-line NSCLC patients that have progressed after anti-PD-(L)1 therapy. We look forward to sharing lung cancer data from both GARNET and AMBER at the Society for the Immunotherapy of Cancer (SITC) Annual Meeting in November.
