A Study Evaluating IPI-926 in Combination With Gemcitabine in Patients With Metastatic Pancreatic Cancer

Phase 1
Completed
Conditions
Metastatic Pancreatic Cancer
Interventions
Registration Number
NCT01130142
Lead Sponsor
Infinity Pharmaceuticals, Inc.
Brief Summary

Study IPI-926-03 is a Phase 1b/2 clinical trial to evaluate IPI 926 in combination with gemcitabine in patients with previously untreated metastatic pancreatic cancer. Phase 1b is designed as a dose escalation study. Once the maximum tolerated dose of IPI-926 in combination with gemcitabine is established in the Phase 1b portion of the study, the Phase 2 portion will commence.

Phase 2 is designed as a randomized, double-blind (investigator/patient), placebo-controlled study. There is no cross-over option for patients in either arm of the Phase 2 (i.e., there is no option for patients receiving placebo to cross-over to IPI-926).

Detailed Description

IPI 926 is an inhibitor of the Hedgehog Pathway. IPI-926 in combination with gemcitabine may improve therapeutic outcomes in patients with pancreatic cancer. Infinity is conducting a Phase 1b/2 clinical trial to evaluate the safety and efficacy of IPI-926 in combination with gemcitabine in patients with previously untreated metastatic pancreatic cancer.

  • Prior treatment with chemotherapy for pancreatic cancer.
  • Known central nervous system metastases
  • Inadequate hematologic function
  • Inadequate hepatic function
  • Inadequate renal function
  • External (percutaneous) biliary drain
  • History of stroke, unstable angina, myocardial infarction, or ventricular arrhythmia requiring medication or mechanical control within the last 6 months.
  • Venous thromboembolic event (e.g., pulmonary embolism or deep vein thrombosis) requiring anticoagulation not appropriately anticoagulated or have NCI CTCAE Grade 2 or greater bleeding episode in the 3 weeks prior to administration of IPI-926
  • Concurrent administration of the medications or foods known to inhibit CYP3A activity to a clinically relevant degree
  • Presence of active infection or systemic use of antibiotics within 72 hours of treatment
  • Significant co-morbid condition or disease which in the judgment of the Investigator would place the patient at undue risk or interfere with the study.

Primary Outcome Measures
NameTimeMethod
Evaluation of safety profile including MTDOnce per week for 3 weeks of a 4 week cycle

To determine the safety profile, including maximum tolerated dose, of IPI-926 plus gemcitabine in patients with previously untreated metastatic pancreatic cancer.

Overall survival comparisonAn average of 6 months

* To compare the overall survival (OS) of patients with previously untreated metastatic pancreatic cancer treated with IPI-926 plus gemcitabine or placebo plus gemcitabine.

* To evaluate the safety of IPI-926 plus gemcitabine or placebo plus gemcitabine.

Secondary Outcome Measures
NameTimeMethod
Measurement of the maximum plasma concentration (Cmax) and area under the concentration versus time curve (AUC0-t) of IPI-926 and gemcitabine.During the 3rd week of the first 4 week cycle

- To evalutate pharmacokinetics (PK) of IPI-926, gemcitabine, and their relevant metabolites.

Comparison of PFS, TTP and ORRAn average of 6 months

- To compare the progression free survival (PFS), time to progression (TTP) and overall response rate (ORR) of patients treated with IPI-926 plus gemcitabine or placebo plus gemcitabine.
