Duration of response, progression-free, and event-free survival in patients treated with panobinostat. (A) Kaplan-Meier estimation of the duration of response (MR or better) end point (n = 17). (B) Kaplan-Meier estimation of the PFS end point (n = 36): PFS was similar to TTP. (C) Kaplan-Meier estimation of the EFS end point (n = 36).
