Cancer drug dosing study could cut clinic visits in half
NCT ID NCT04295863
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether two common cancer immunotherapy drugs (nivolumab and pembrolizumab) can be given less often than the current standard schedule. About 264 adults with advanced or metastatic cancer will be randomly assigned to receive the drugs at standard intervals or extended intervals. Researchers will compare drug levels in the blood to see if the extended schedule keeps levels high enough to control the disease.
