Description of intervention(s) / exposure
Treatment: Drugs - AFQ056

Experimental: AFQ056 Treatment - 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.


Treatment: Drugs: AFQ056
The investigational drug, AFQ056, will be provided as hard gelatin capsules. Two different oral dosage strengths,25mg and 100 mg, identical in appearance, will be used.
