NCT ID NCT05936359
First seen Jun 27, 2026 · Last updated Aug 11, 2026 · Updated 2 times
Summary
This early-stage trial is testing a new drug called INCA033989, alone or with an existing drug ruxolitinib, in 225 people with myeloproliferative neoplasms (a group of blood cancers). The main goal is to check safety and find the best dose. Participants must have a specific genetic mutation (CALR) and be willing to have bone marrow tests.

- Active substance
- INCA033989 and ruxolitinib
- What this could lead to
- If successful, this could lead to a new treatment option for myeloproliferative neoplasms, potentially improving symptom control and reducing spleen size.
- What could go wrong
- This is an early Phase 1 trial focused on safety and dosing, so it is not yet known if the drug works. Side effects and limited effectiveness are possible.
