10 Million apologies if someone already posted this, but I signed up to get drug notification e-mails from the FDA. Unable to do link, so I copy and pasted:
The Division of Drug Information (DDI) - serving the public by providing information on human drug products and drug product regulation by FDA
The U.S. Food and Drug Administration is alerting health care professionals, oncology clinical investigators, and the public about decreased survival associated with the use of Keytruda (pembrolizumab) or Tecentriq (atezolizumab) as single therapy (monotherapy) in clinical trials to treat patients with metastatic urothelial cancer who have not received prior therapy and who have low expression of the protein programmed death ligand 1 (PD-L1).
In two ongoing clinical trials (KEYNOTE-361 and IMVIGOR-130), the Data Monitoring Committees’ (DMC) early reviews found patients in the monotherapy arms of both trials with PD-L1 low status had decreased survival compared to patients who received cisplatin- or carboplatin-based chemotherapy. There was no change in the adverse event profile of Keytruda or Tecentriq. Both Merck, manufacturer of Keytruda, and Genentech, manufacturer of Tecentriq, have stopped enrolling patients whose tumors have PD-L1 low status to the Keytruda or Tecentriq monotherapy arms per the DMCs’ recommendations.
The clinical trials compare platinum-based chemotherapy combined with Keytruda or Tecentriq to platinum-based chemotherapy alone. Both trials enrolled a third arm of monotherapy with Keytruda or Tecentriq to compare to platinum-based chemotherapy alone. The monotherapy arms remain open only to patients whose tumors have PD-L1 high status. The combination arms and the chemotherapy arms of both studies also remain open. The FDA is reviewing the findings of the ongoing clinical trials and will communicate new information as necessary.
Both Keytruda and Tecentriq are currently approved under accelerated approval for the treatment of locally advanced or metastatic urothelial carcinoma patients who are not eligible for cisplatin-containing chemotherapy, irrespective of PD-L1 status. Patients taking Keytruda or Tecentriq for other approved uses should continue to take their medication as directed by their health care professional.

I am not a trained financial professional, and all posts are my bar stool amateur opinion.
