Phase 3 Study of Radotinib for Adults with Chronic Phase Philadelphia Chromosome-Positive Chronic Myeloid Leukemia After Failure or Intolerance to Previous Tyrosine Kinase Inhibitors Including Imatinib

What this Trial Is About

Researchers are evaluating the effects of Radotinib in patients with chronic phase Philadelphia chromosome-positive chronic myeloid leukemia who have not responded well or cannot tolerate previous tyrosine kinase inhibitor treatments, including Imatinib. This multinational Phase III study aims to assess the efficacy and safety of Radotinib in this specific patient group. A total of 173 participants are expected to enroll in this single-arm, open-label trial. Participants will receive Radotinib at a dose of 400 mg twice daily, taken orally every 12 hours, for 12 months. Dose adjustments may be made if participants experience certain blood-related or other toxicities, with up to two reductions allowed per stage to 600 mg and then 400 mg. The study monitors patients closely to manage any side effects and ensure compliance with the dosing schedule. Throughout the study, participants will undergo regular assessments, including cytogenetic and molecular response evaluations at 6, 12, and 24 months. Researchers will track major cytogenetic response at 6 months as the primary outcome, with additional measures of overall survival and progression-free survival by 24 months. Safety and tolerability will also be monitored, with follow-up lasting up to two years to evaluate long-term effects and disease progression.
