Summary: A Phase Ib and II Open-Label, Multi-Center Study of MEDI4736 Evaluated in Different Combinations in Patients with Metastatic Pancreatic Ductal Adenocarcinoma

Detailed description: This is a Phase Ib and II open-label, multi-center study to evaluate the safety, tolerability, pharmacodynamics, and antitumor activity of MEDI4736 in combination with chemotherapy and novel anticancer agents in patients with pancreatic ductal adenocarcinoma (PDAC). This study will consist of 2 independent cohorts.

At least 1 lesion, not previously irradiated, that can be accurately measured at baseline as ≥10 mm in the longest diameter (except lymph nodes, which must have short axis ≥15 mm) with computed tomography (CT) or magnetic resonance imaging (MRI) scan and that is suitable for accurate repeated measurements
  4. MEDI4736 + nab-paclitaxel + gemcitabine chemotherapy cohort: treatment-naïve patients with metastatic PDAC who have received no previous systemic chemotherapy 5 MEDI4736 + Cohort: Patient should receive no more than 1 prior chemotherapy regimen or any other systemic therapy for recurrent/metastatic PDAC
