NCT ID NCT04324112

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial tests whether a combination of two oral drugs, encorafenib and binimetinib, works better than the current drug vemurafenib for people with hairy cell leukemia that has a BRAF mutation and has either not responded to treatment or returned. About 28 adults will take the pills daily in 28-day cycles. The goal is to see if this combo can achieve a complete remission more often than existing options.
