Drugs & Targets FDA approves pembrolizumab plus axitinib for advanced RCC

FDA approved pembrolizumab plus axitinib (Keytruda) for the first-line treatment of patients with advanced renal cell carcinoma.

Keytruda is sponsored by Merck.

Approval was based on KEYNOTE‑426 (NCT02853331), a randomized, multicenter, open-label trial conducted in 861 patients who had not received systemic therapy for advanced RCC. Patients were enrolled regardless of PD-L1 tumor expression status and were randomly allocated to receive either pembrolizumab 200 mg intravenously every 3 weeks in combination with axitinib 5 mg orally twice daily, or sunitinib 50 mg orally once daily for 4 weeks and then off treatment for 2 weeks.

Treatment was continued until confirmed disease progression or unacceptable toxicity. Pembrolizumab was received for a maximum of 24 months.

The main efficacy measures were overall survival and progression-free survival, assessed by blinded independent central review (RECIST 1.1.) The trial demonstrated a statistically significant improvement in OS in a pre-specified interim analysis for patients on the pembrolizumab plus axitinib arm (HR 0.53; 95% CI: 0.38, 0.74; p<0.0001).

With deaths reported in 18% of patients, the median OS was not reached in either arm. The 12-month OS rate was 90% in the pembrolizumab plus axitinib arm and 78% for those treated with sunitinib. The trial also demonstrated a PFS … Continue reading FDA approves pembrolizumab plus axitinib for advanced RCC
