The efficacy of Iclusig was evaluated in OPTIC (NCT02467270), a dose-optimization trial. Eligible patients had CP-CML whose disease was considered to be resistant or resistant/intolerant to at least 2 prior kinase inhibitors or who have the T315I mutation.
Of the 45 patients who had a dose reduction after achieving ≤1% BCR-ABL1IS, 28 patients (62%) maintained their response at the reduced dose for at least 90 days. Of these 28 patients, 18 patients (64%) maintained the response for at least one year. Median duration of response (MR2) was not reached.
The efficacy of Iclusig was evaluated in PACE (NCT01207440), a single-arm, open-label, international, multicenter trial.
In patients with CP-CML who achieved MCyR or MMR, the median time to response was 3 months (range: 1.8 to 12.3 months) and 6 months (range: 2 to 60.2 months), respectively. With a minimum follow-up of 60 months, the median durations of MCyR (range: 1 day to 70.1 months) and MMR (range: 1 day to 67.8 months) had not yet been reached.
