Study Arms:
- AFQ056 Treatment (Type: EXPERIMENTAL): All patients will initiate treatment with AFQ056 at a starting dose of 25 mg b.i.d. The dose will be titrated from 25 mg b.i.d to 50 mg b.i.d., 75 mg b.i.d. and 100 mg b.i.d. at weekly intervals. Dose adjustments (up- and down-titrations) will be permitted as needed to manage any tolerability issues and to ensure that patients reach their highest tolerated dose, not to exceed 100 mg b.i.d.

Based on this trial design, predict the completion outcome and termination type (if applicable).
