FDA's Oncologic Drugs Advisory Committee is meeting to review 6 indications for 3 drugs (including 3 indications for Keytruda) which had accelerated approval.
I don't keep up with cancer drugs and trials so this may be old news, but it appears there will be less competition for cancer indications. Excerpts are pasted below.

Six indications for immune checkpoint inhibitors (ICIs) granted under the FDA’s accelerated approval process that later failed confirmatory clinical trials are being reassessed as the agency continues an industry-wide evaluation of the pathway.
The FDA’s Oncologic Drugs Advisory Committee (ODAC) will hold a special 3-day public hearing on April 27 to 29 to allow expert commentary and patient testimony about the drugs, which are being used to treat triple-negative breast cancer (TNBC), metastatic urothelial carcinoma (mUC), gastric cancers, and hepatocellular carcinoma (HCC), the agency said Thursday. Based on the testimony, ODAC will consider whether the approvals should be withdrawn and whether additional trials should be conducted.
The hearings will involve 2 indications for atezolizumab (Tecentriq), 3 for pembrolizumab (Keytruda), and 1 for nivolumab (Opdivo). Specifically, these indications will be reviewed:
Atezolizumab―in combination with nab-paclitaxel (Abraxane) for the treatment of patients with PD-L1–positive unresectable locally advanced or metastatic TNBC; and as monotherapy for patients with locally advanced or mUC who are not eligible for cisplatin-containing chemotherapy
Pembrolizumab—as monotherapy for patients with locally advanced or mUC who are not eligible for cisplatin-containing chemotherapy; for patients with recurrent locally advanced or metastatic gastric or gastroesophageal junction adenocarcinoma that express PD-L1 and has progressed after 2 or more prior lines of therapy; and for patients with HCC previously treated with sorafenib (Nexavar)
Nivolumab—as a single agent for patients with HCC who previously received sorafenib
The FDA announced the hearings after a flurry of ICI indications were voluntarily withdrawn by pharmaceutical companies, starting in December 2020, as part of what the FDA described as an industry-wide evaluation of accelerated approvals in oncology “in which confirmatory trials did not confirm clinical benefit.”
As part of the voluntary withdrawals, Bristol Myers Squibb and Merck said they will discontinue indications for nivolumab and pembrolizumab, respectively, for patients with metastatic small cell lung cancer whose disease has progressed after platinum-based chemotherapy and at least 1 other line of therapy; AstraZeneca will withdraw an indication for durvalumab (Imfinzi) for patients with locally advanced or mUC that has progressed after chemotherapy or within 12 months of neoadjuvant or adjuvant chemotherapy; and Genentech will halt an indication for atezolizumab for patients with mUC previously treated with platinum-based chemotherapy.
Under the accelerated approval program, drugs are able to gain indications more quickly than through a regular approval timeline based on a surrogate end point. Pharmaceutical companies are then required to conduct a trial that confirms a clinical benefit; if the study is successful, the FDA grants regular approval status.2
