FDA approves pembrolizumab for BCG-unresponsive NMIBC with CIS


The Food and Drug Administration has approved pembrolizumab (Keytruda) for the treatment of patients with Bacillus Calmette-Guérin (BCG)–unresponsive, high-risk, non–muscle invasive bladder cancer (NMIBC) with carcinoma in situ (CIS), with or without papillary tumors, who are ineligible for or have elected not to undergo cystectomy.

The approval was based on response in a single-arm trial of 148 patients with high-risk NMIBC, 96 of whom had BCG-unresponsive CIS with or without papillary tumors, the FDA said in a statement.

The complete response rate in the 96 patients with high-risk BCG-unresponsive NMIBC with CIS was 41% (95% confidence interval, 31-51) and median response duration was 16.2 months.

The most common adverse reactions in patients who received pembrolizumab in the trial were fatigue, diarrhea, rash, pruritus, musculoskeletal pain, hematuria, cough, arthralgia, nausea, constipation, urinary tract infection, peripheral edema, hypothyroidism, and nasopharyngitis.

The recommended dose is 200 mg every 3 weeks, the FDA said.
