Martin H. Voss, medical oncologist, Memorial Sloan Kettering Cancer Center, discusses results of a randomized phase I/II trial (NCT02118337) looking at the combination of MEDI0680 and durvalumab (Imfinzi) versus nivolumab (Opdivo) in metastatic renal cell carcinoma (mRCC).
For the phase I/II trial, investigators set out to evaluate the safety, tolerability, pharmacokinetics, immunogenicity, and antitumor activity of MEDI0680 in combination with durvalumab compared with nivolumab monotherapy in immunotherapy-naïve patients with metastatic clear cell renal cell carcinoma.
However, no significant difference in overall response rate, progression-free survival, or overall survival was observed between the 2 arms of this trial, says Voss. Furthermore, no subgroups appeared to derive additional benefit from the combination versus the single-agent, explains Voss.
Results from a safety analysis showed that grade 3/4 treatment-related adverse events (TRAEs) occurred in 26% of patients who received the combination versus 19% who received nivolumab. Furthermore, 12% of patients discontinued treatment as a result of TRAEs compared with 5%, respectively, Voss concludes.
