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.
