Official Title  ICMJE A Phase IIa, Multicenter, Open-label Study to Assess the Safety and Efficacy of the Combination of BL-8040 and Pembrolizumab in Patients With Metastatic Pancreatic Cancer, the COMBAT Study
Brief Summary This study will assess the efficacy and safety of BL-8040 in combination with pembrolizumab (Keytruda®) and BL8040/ Pembrolizumab in combination with liposomal irinotecan (Onivyde®)/5-fluorouracil/leucovorin (5-FU/LV) in subjects with metastatic pancreatic adenocarcinoma.
Detailed Description

This will be an open-label, two-cohort, phase IIa study in subjects with metastatic pancreatic adenocarcinoma.

The study will be comprised of 2 cohorts,. Each includes approximately 40 subjects with unresectable metastatic pancreatic adenocarcinoma.

Each cohort study consists of two periods:

  • Monotherapy period: One week, with BL-8040 administered daily on days 1-5.
  • Combination therapy:

Cohort 1: Three-week cycles of a combination of BL-8040 administered three times a week (TIW) and pembrolizumab administered once every three weeks.

Cohort 2: Onivyde®/5-FU/LV every 2 weeks, pembrolizumab once every 3 weeks and BL-8040 twice a week.

Cohort 1: Subjects with metastatic pancreatic adenocarcinoma will be enrolled and receive BL-8040 monotherapy for five days followed by a combination treatment of BL-8040 and pembrolizumab. During the monotherapy period, eligible subjects will receive daily subcutaneous (SC) injections of BL-8040 (1.25 mg/kg) on Days 1 - 5.

From Day 8, subjects will begin a combination period consisting of treatment with SC BL-8040 TIW and pembrolizumab once every three weeks. The combination therapy will continue for up to 35 cycles of pembrolizumab approximately two years), or until progression, clinical deterioration or Early Termination, whichever comes first.

Cohort 2: Subjects with metastatic pancreatic adenocarcinoma that have progressed following first-line treatment with gemcitabine-based chemotherapy will be enrolled and receive BL-8040 monotherapy for five days followed by a combination treatment of BL-8040, pembrolizumab and chemotherapy. During the monotherapy period, eligible subjects will receive daily SC injections of BL-8040 on Days 1 - 5.

From Day 8, subjects will begin a combination period consisting of:

  • IV Onivyde® followed by IV leucovorin (LV), followed by IV fluorouracil (5-FU), every 2 weeks.
  • Pembrolizumab every three weeks.
  • BL-8040 twice a week

The combination therapy will continue for up to 35 treatments (approximately two years), or until progression, clinical deterioration or Early Termination, whichever comes first.
