Study Evaluating IPI-504 in Patients With Gastrointestinal Stromal Tumors (GIST) Following Failure of at Least Imatinib and Sunitinib

Gastrointestinal Stromal Tumors Clinical Trial

Official title: A Phase 3 Randomized, Double-Blind, Placebo-Controlled, Multi-Center Study Evaluating the Efficacy and Safety of IPI-504 in Patients With Metastatic and/or Unresectable GIST Following Failure of at Least Imatinib and Sunitinib

Status Terminated

Clinical Trial Summary

IPI-504-06 is a Phase 3, randomized, double-blind, placebo-controlled, multi-center study to evaluate the efficacy and safety of IPI-504 as compared to placebo in patients with metastatic and/or unresectable GIST following failure of at least imatinib and sunitinib.

Approximately 195 patients will be randomized using a 2:1 ratio to receive either IPI-504 (N=130) or placebo (N=65). Upon unblinding, patients receiving either IPI-504 or placebo may receive IPI-504 in the open-label portion of the study if defined inclusion criteria are met.

Early and frequent imaging timepoints (Weeks 2, 5, 8, 14 and every 6 weeks thereafter) are incorporated into this study to capture progression events and limit patient exposure to ineffective agents.
