A Study of Vantictumab (OMP-18R5) in Combination With Nab-Paclitaxel and Gemcitabine in Previously Untreated Stage IV Pancreatic Cancer

Phase 1

Completed

• Conditions: Pancreatic Cancer; Stage IV Pancreatic Cancer
• Interventions: Drug: Vantictumab; Drug: Nab-Paclitaxel; Drug: Gemcitabine

• Registration Number: NCT02005315
• Lead Sponsor: OncoMed Pharmaceuticals, Inc.

Brief Summary

This is an open-label Phase 1b dose-escalation study to assess the safety, tolerability, and PK of vantictumab when combined with nab-paclitaxel and gemcitabine.

Detailed Description

Once the maximum tolerated dose (MTD) or maximum administered dose (MAD) has been determined, up to 10 patients may be enrolled in the cohort-expansion phase to better characterize the safety, tolerability and PK of vantictumab combined with nab-paclitaxel and gemcitabine. Up to approximately 34 patients may be enrolled into the study.

Primary Outcome Measures

Name	Time	Method
Phase 1b: Safety and tolerability of vantictumab in combination with nab-paclitaxel and gemcitabine in patients with previously untreated Stage IV pancreatic cancer	Subjects will be treated and observed for DLT through the end of the first cycle (Days 0-28)	The maximum tolerated dose (MTD) will be determined in patients treated with vantictumab in combination with weekly nab-paclitaxel

Secondary Outcome Measures

Name	Time	Method
Pharmacokinetics (PK) of vantictumab when administered in combination with nab-paclitaxel and gemcitabine to patients with previously untreated Stage IV pancreatic cancer	Vantictumab will be administered IV on Days 1 and 15 of each 28-day cycle. Nab-paclitaxel and gemcitabine will be administered IV on Days 1, 8, and 15 of each cycle.	Apparent half life, AUC, clearance, volume of distribution
