The beleaguered PI3K-delta inhibitor space took another blow after MEI Pharma Inc. and partner Kyowa Kirin Co. Ltd. said the U.S. FDA won’t greenlight zandelisib without data from a randomized study.

Innovent Biologics Co. Ltd. and Eli Lilly and Co. are "assessing next steps" for their jointly developed PD-1 inhibitor, sintilimab, following receipt of a complete response letter (CRL) from the U.S. FDA. The pair sought approval of a BLA for sintilimab plus pemetrexed and platinum chemotherapy for the first-line treatment of people with nonsquamous non-small-cell lung cancer (NSCLC) but found near-unanimous opposition from FDA advisers dissatisfied with China-only trial data submitted in support of the application. The medicine is already approved for multiple indications in China, where it’s marketed as Tyvyt.

The treatment is the indication’s first FDA-approved targeted radioligand therapy that contains a radioisotope.
