Phase 3 Trial Comparing INCA033989 to Best Available Therapy for Adults with Essential Thrombocythemia and CALR Mutation Previously Treated with Cytoreductive Therapy

What this Trial Is About

Researchers are comparing INCA033989 with the best available therapy for adults who have essential thrombocythemia ET with a CALR mutation and have previously received cytoreductive treatment. The study aims to evaluate the effects of these treatments on this specific patient group. It is a Phase 3 clinical trial sponsored by Incyte Corporation to assess treatment responses and safety. Participants will be randomly assigned to receive either INCA033989 administered intravenously or the best available therapy chosen by their doctor. The treatments are given according to the study protocol. The study focuses on treatment outcomes over a period of weeks, including response durability and symptom changes, with assessments at specified timepoints. During the study, participants will have regular visits to monitor their clinical and hematologic responses, symptoms, and any side effects. Researchers will collect data on mutation levels, symptom questionnaires, and fatigue assessments up to 48 weeks. Safety monitoring will continue for 60 days following the last dose. The total duration of participation may extend up to several months as outlined by the trial schedule.
