NCT ID NCT07008118
First seen Jun 27, 2026 · Last updated Aug 07, 2026 · Updated 6 times
Summary
This early-stage trial tests a new drug, INCA035784, in 120 adults with myeloproliferative neoplasms (a group of blood cancers). The main goal is to check safety and find the right dose. Participants must have a specific genetic mutation (CALR) and have tried other treatments before.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- INCA035784
- What this could lead to
- If successful, this could point toward a new treatment option for certain blood cancers called myeloproliferative neoplasms.
- What could go wrong
- This is an early Phase 1 trial focused on safety, not effectiveness. It is small and may not lead to a working treatment. Side effects are unknown.
