Following recent discussions with FDA, Bristol-Myers Squibb announced the voluntary withdrawal of the sBLA for the Opdivo and low-dose Yervoy (ipilimumab) combination for treatment of first-line advanced non-small cell lung cancer in patients with tumor mutational burden ≥10 mutations/megabase.

In October 2018, the company announced the submission of an exploratory overall survival analysis for the TMB <10 mut/Mb subgroup to the FDA. The FDA determined at that time, that the submission of this new information constituted a major amendment to the sBLA and extended the review period by three months, moving the Prescription Drug User Fee Act date to May 20, 2019.

After recent discussions with the FDA, the company believes further evidence on the relationship between TMB and PD-L1 is required to fully evaluate the impact of Opdivo plus Yervoy on OS in first-line NSCLC patients.

This analysis will require availability of the final data from Checkmate -227, Part 1a (Opdivo plus low-dose Yervoy or Opdivo monotherapy versus chemotherapy in patients whose tumors express PD-L1), which the company anticipates will be available in the first-half of 2019. Since these data from Checkmate -227, Part 1a, will not be available within the review cycle of the current application the company decided to withdraw.

In January, the company announced the European Commission approved the combination of Opdivo plus Yervoy for the first-line treatment of patients with intermediate- and poor-risk advanced renal cell carcinoma.

There is general agreement that the United States spends too much on health care, especially on pharmaceuticals.  But what we spend on drugs is not simply a function of price.

When I first proposed targeting PCNA (proliferating cell nuclear antigen) as a therapeutic approach, the response I got was: “No one will ever make a drug against PCNA. It’s undruggable.” The protein lacks enzymatic activity, has a disordered region, and binds to over 200 other proteins within the cell. From a traditional drug development perspective, these characteristics made PCNA an impossible target.
