Phase 1b/2 Study of Retaspimycin HCl (IPI-504) in Combination With Everolimus in KRAS Mutant Non-small Cell Lung Cancer

Phase 1
Completed
Conditions
Non-small Cell Lung Cancer
Interventions
Registration Number
NCT01427946
Lead Sponsor
Infinity Pharmaceuticals, Inc.
Brief Summary

Study IPI-504-15 is a Phase 1b/2 clinical trial to evaluate the safety and efficacy of retaspimycin HCl (IPI-504) plus everolimus in patients with KRAS mutant Non-small Cell Lung Cancer (NSCLC).

Detailed Description

This is a Phase Ib/2 study of retaspimycin HCl (IPI-504) in combination with everolimus. The Phase 1b portion is to test the safety and tolerability of retaspimycin HCl (IPI-504) in combination with everolimus and determine the highest dose of retaspimycin HCl (IPI-504) and everolimus that can safely be given in combination. The Phase 2 portion of this study will continue the evaluation of safety of retaspimycin HCl (IPI-504) in combination with everolimus and compare the effect of the study drugs on tumor response and life expectancy in patients with KRAS mutant NSCLC.
