A Phase Ib/II Dose-finding Study to Assess the Safety and Efficacy of LDE225 + INC424 in Patients With MF

A Phase Ib/II, Open-label, Multi-center, Dose-finding Study to Assess the Safety and Efficacy of the Oral Combination of LDE225 and INC424 (Ruxolitinib) in Patients With Myelofibrosis

The purpose of this phase Ib/II clinical trial was to: a) evaluate the safety of the co-administration of LDE225 and INC424 in myelofibrosis patients and establish a maximum tolerated dose and/or Recommended Phase II dose of the combination and b) to assess the efficacy of the co-administration of LDE225 and INC424 on spleen volume reduction.

The study is considered to have been completed because the participants completed the study as per study design at the time of trial termination. If participants were already in extension phase until discontinuation criteria were met or alternative setting was available, they were considered as completed. The study was terminated due to one of the compounds being divested.
