Description

Description

Primary Objectives:
  • To determine the maximum tolerated dose (MTD) of tarextumab when administered every other week (Days 1 and 15) in combination with nab-paclitaxel 125 mg/m2 and gemcitabine 1000 mg/m2 on Days 1, 8 and 15 of every 28-day cycle in subjects with previously untreated stage IV pancreatic cancer (Phase 1b portion)
  • To determine the clinical benefit, as measured by overall survival (OS) of the addition of tarextumab to nabpaclitaxel and gemcitabine (Nab-P+Gem) in all subjects who are receiving first-line therapy for stage IV pancreatic cancer (Phase 2 portion)
  • To determine the clinical benefit, as measured by OS of the addition of tarextumab to Nab-P+Gem across the four subject subsets: subjects with Notch3 ≥25th percentile, subjects with Notch3 ≥50th percentile, subjects with Notch3 ≥75th percentile and all subjects receiving first-line therapy for stage IV pancreatic cancer
Secondary Objectives:
  • To determine the pharmacokinetics of tarextumab in combination with Nab-P+Gem in subjects with previously untreated stage IV pancreatic cancer (Phase 1b and 2 portions)
  • To determine the immunogenicity of tarextumab in combination with Nab-P+Gem in subjects with previously untreated stage IV pancreatic cancer (Phase 1b and 2 portions)
  • To estimate the clinical benefit, as measured by Progression free survival (PFS), 12 months OS rate and overall response rate (ORR) of the addition of tarextumab to Nab-P+Gem in all subjects who are receiving first-line therapy for stage IV pancreatic cancer (Phase 2 portion)
  • To determine the clinical benefit, as measured by PFS of the addition of tarextumab to Nab-P+Gem across the four subject subsets: subjects with Notch3 ≥25th percentile, subjects with Notch3 ≥50th percentile, subjects with Notch3 ≥75th percentile and all subjects receiving first-line therapy for stage IV pancreatic cancer (Phase 2 portion)
  • To determine the safety and tolerability of tarextumab in combination with Nab-P+Gem in subjects with stage IV pancreatic cancer (Phase 1b and 2 portions in subjects receiving tarextumab with Nab-P+Gem)
Exploratory Objectives:
  • To assess exploratory pharmacodynamic biomarkers, including Notch pathway related genes and proteins and circulating tumor cells following tarextumab treatment
  • To correlate the clinical benefit, as measured by PFS of the addition of tarextumab to Nab-P+Gem in subjects receiving first-line therapy for stage IV pancreatic cancer with Notch3 high expression level (Phase 1b)
  • To estimate the clinical benefit, as measured by response of CA19-9 (≥50% reduction from the baseline) of the addition of tarextumab to Nab-P+Gem in all subjects who are receiving first-line therapy for stage IV pancreatic cancer (Phase 2 portion)
  • To evaluate the dependence of the clinical benefit, as measured by response of CA19-9 (≥50% reduction from the baseline) of the addition of tarextumab to Nab-P+Gem in subjects who are receiving first-line therapy for stage IV pancreatic cancer on the level of Notch3 expression level (Phase 2 portion)
