Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Core imatinib

Depending on the participants' randomized treatment in the core study, CQTI571A2301 (NCT00902174), and their completion status in the core study, participants received imatinib at 200 mg qd, 400 mg qd, or 200 mg qd with an increase to 400 mg qd after 2 weeks, if tolerated.

Group Type EXPERIMENTAL

Imatinib

Intervention Type DRUG

Participants, who received imatinib 200 mg in the core study, CQTI571A2301 (NCT00902174), and completed the core study, received imatinib 200 mg every day (qd) in the extension. Participants, who were randomized to receive imatinib 400 mg in the core study and completed the core study, received imatinib 400 mg qd in the extension. Participants, who terminated early from the core study or who were randomized to placebo and completed the core study, started the extension with imatinib 200 mg qd. After 2 weeks, the dose was increased to 400 mg qd if tolerated.

Placebo

Intervention Type DRUG

To preserve the blind of the core study until the core study, CQTI571A2301 (NCT00902174), was completed, participants received a blinded study drug package containing a 70-tablet bottle of imatinib and a 70-tablet bottle of matching placebo.

Core placebo

Depending on the participants' randomized treatment in the core study, CQTI571A2301 (NCT00902174), and their completion status in the core study, participants received imatinib at 200 mg qd, 400 mg qd, or 200 mg qd with an increase to 400 mg qd after 2 weeks, if tolerated.

Group Type EXPERIMENTAL

Intervention Type DRUG

Participants, who were randomized to receive imatinib 400 mg in the core study and completed the core study, received imatinib 400 mg qd in the extension. Participants, who terminated early from the core study or who were randomized to placebo and completed the core study, started the extension with imatinib 200 mg qd. After 2 weeks, the dose was increased to 400 mg qd if tolerated.

Placebo

Intervention Type DRUG

To preserve the blind of the core study until the core study, CQTI571A2301 (NCT00902174), was completed, participants received a blinded study drug package containing a 70-tablet bottle of imatinib and a 70-tablet bottle of matching placebo.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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)
