Estimated Enrollment: 160
Study Start Date: April 2010
Estimated Study Completion Date: May 2014
Estimated Primary Completion Date: May 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 200 mg imatinib mesylate Drug: imatinib
Experimental: 400 mg imatinib mesylate Drug: imatinib

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patients who participated in CQTI571A2301 clinical trial and completed the week 24 visit of the study protocol, including all Study Completion assessments
  • Patients who withdrew from the CQTI571A2301 study prematurely for reasons not related to study drug or not related to a safety issue but performed all Study Completion assessments

Exclusion Criteria:

  • Patients with a pulmonary capillary wedge pressure > 15 mmHg at time of Study Completion assessments in core protocol CQTI571A2301. If pulmonary capillary wedge pressure is not attainable, then a left atrial pressure measurement may be used in its place.
  • LVEF < 45%
  • Patients with thrombocytopenia, platelet count < 50E9/L (50E3/µL)
  • Patients with uncontrolled systemic arterial hypertension, systolic > 160 mmHg or diastolic > 90 mmHg
  • Patients with a QTcF > 450 ms for males and > 470 ms for females in the absence of right branch bundle block (based on Visit 1 ECG if required to be performed)

Other protocol-defined inclusion/exclusion criteria may apply
