Myeloproliferative neoplasms (MPN)
A study to Evaluate INCA033989 Administered as a Monotherapy or in Combination With Ruxolitinib in Participants with Myeloproliferative Neoplasms
Clinical Study Purpose
This study is being conducted to evaluate the safety, tolerability, dose-limiting toxicity (DLT) and determine the maximum tolerated dose (MTD) and/or recommended dose(s) for expansion (RDE) of INCA033989 administered as a Monotherapy or in Combination With Ruxolitinib in participants with myeloproliferative neoplasms.
