FDA Concerns with PD-1/PD-L1 Inhibitors Spread to Roche Studies

Continuing FDA safety concerns involving PD-1/PD-L1 inhibitors have spread to two Roche clinical trials. A Phase 1b and Phase 1b/2 involving Tecentriq have been placed on partial clinical hold, according to Roche.

Last month, CDER director Janet Woodcock said the agency was stepping up its safety surveillance on PD-1/PD-L1 inhibitors after an investigational clinical trial involving Merck’s Keytruda (pembrolizumab) in combination with other therapies in multiple myeloma patients “found an excess of deaths for patients receiving Keytruda when combined with these other drugs.” The agency, she said, is working with sponsors of similar cancer drugs to examine other trials in which these drugs are being studied in combination with other drugs.

“It is our understanding that the FDA is evaluating all ongoing blood cancer trials investigating an anti-PD1/PDL1 medicine in combination with an immunomodulatory medicine to determine if it is a class-wide (anti-PD1/PDL1) concern in multiple myeloma/blood cancers or a specific concern with certain combinations with immunomodulatory medicines,” Roche says. “The two studies include cohorts evaluating Tecentriq in combination with an immunomodulatory medicine (IMiDs) in relapsed/refractory multiple myeloma and relapsed/refractory follicular lymphoma. While the partial clinical hold is in place, patients who are currently enrolled in these trials and are deriving clinical benefit may continue to receive treatment, but no additional patients will be enrolled.”
