Nivolumab Wins First-Line Indication in Metastatic UC
The US Food and Drug Administration has approved nivolumab (Opdivo, Bristol-Myers Squibb) in combination with cisplatin and gemcitabine for first-line treatment of adults with unresectable or metastatic urothelial carcinoma.
Approval was based on the CHECKMATE-901 trial in 608 patients randomized equally to either cisplatin and gemcitabine for ≤ six cycles or nivolumab plus cisplatin and gemcitabine for ≤ six cycles, followed by nivolumab alone for ≤ 2 years.
Median overall survival was 21.7 months with nivolumab add-on vs 18.9 months with cisplatin/gemcitabine alone (hazard ratio [HR], 0.78; P = .0171). The nivolumab group had a slightly higher median progression-free survival of 7.9 months vs 7.6 months in the cisplatin and gemcitabine group (HR, 0.72; P = .0012).
The most common adverse events, occurring in ≥ 15% of nivolumab patients, were nausea, fatigue, musculoskeletal pain, constipation, decreased appetite, rash, vomiting, peripheral neuropathy, urinary tract infection, diarrhea, edema, hypothyroidism, and pruritus.
Among numerous other oncology indications, nivolumab was previously approved for adjuvant treatment following urothelial carcinoma resection and for locally advanced or metastatic urothelial carcinoma that progresses during or following platinum-containing chemotherapy.
