Brief Summary:
In a multicenter, single-arm, open-label and Phase III Radotinib clinical study, chronic phase Ph+ chronic myeloid leukemia patients with resistance or Intolerance to previous TKIs therapy including Imatinib will be recruited. In this phase 3 study, 195 subjects are expected to be enrolled in a single arm with the administration of Radotinib 400mg twice daily, which includes 20% of dropout rate.

Condition or disease Intervention/treatment Phase
Leukemia, Myeloid, Chronic Phase Drug: Radotinib Phase 3

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 195 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 3 Multi-center, Single-arm, Open-label Study for the Efficacy and Safety of Radotinib in Chronic Phase Chronic Myeloid Leukemia Patients With Resistance or Intolerance to Previous TKIs Therapy Including Imatinib
Actual Study Start Date : June 25, 2018
Estimated Primary Completion Date : March 15, 2020
Estimated Study Completion Date : April 1, 2022


Arm Intervention/treatment
Experimental: Radotinib

Enrolled subjects will continue to administer radotinib 400mg twice daily (800mg/day) orally every 12 hours at regular dosing hours for 12 months.

Dose modification is allowed if the subject cannot comply with the protocol-defined dosing schedule due to hematologic or non-hematologic toxicities and toxicities resolve within 28 days (within 42 days for hematologic toxicities). For radotinib, maximum 2 dose reductions will be allowed by stage to 600mg and to 400mg.

Primary Outcome Measures :
  1. Major Cytogenetic Response (MCyR) [ Time Frame: at month 6 ]
    MCyR is defined as 0~35% CCyR+PCyR based on ≥20 metaphase myelocytes. Chromosome test results from <20 metaphase myelocytes will be excluded from the analysis.


Secondary Outcome Measures :
  1. Cytogenetic Response (CCyR) [ Time Frame: at month 12/24, by month 24 ]
    CCyR is defined as complete loss of Ph chromosome based on ≥20 metaphase myelocytes. Chromosome test results from <20 metaphase myelocytes will be excluded from the analysis.

  2. Major molecular response [ Time Frame: at month 12/24, by month 24 ]
    MMR is defined as a ≥3-log reduction in BCR-ABL1 transcript level from the standardized reference or BCR-ABL1/ABL % of ≤0.1% according to the international reference when the level of BCR-ABL1 gene was measured by RQ-PCR, a standardized quantitative genetic method.

  3. Overall Survival(OS) [ Time Frame: by month 24 ]
    OS is defined as the duration from the first day of Radotinib administration to the day of death for certain causes.

  4. Progression Free Survival (PFS) [ Time Frame: by month 24 ]
    PFS is defined as the duration from the first day of Radotinib administration to the earliest day of disease progression or death for certain causes.


Other Outcome Measures:
  1. BCR-ABL1 point mutation [ Time Frame: up to month 24 ]
    Incidence rate of BCR-ABL1 point mutations that are newly found during the course of radotinib treatment

  2. correlation between the concentration of radotinib in blood and the response (efficacy and safety) [ Time Frame: up to month 24 ]
    To measure the concentration of radotinib in blood

  3. Incidence of Radotinib-Adverse Events [ Time Frame: up to month 24 ]
    Toxicities will be evaluated in all subjects treated with radotinib.
