Olaptesed With Pembrolizumab and Nanoliposomal Irinotecan or Gemcitabine/Nab-Paclitaxel in MSS Pancreatic Cancer

Официальное название

An Open-label Phase 2 Study of Olaptesed Pegol (NOX-A12) Combined With Pembrolizumab and Nanoliposomal Irinotecan/5-FU/Leucovorin or Gemcitabine/Nab-paclitaxel in Microsatellite-stable Metastatic Pancreatic Cancer Patients

Обзор

The purpose of this study is to provide a go/no-go decision for a randomized expansion study by assessing the disease control rate (DCR) at 6 weeks for the combination of olaptesed pegol on top of pembrolizumab and (Arm 1) nanoliposomal irinotecan, 5-FU and leucovorin or (Arm 2) gemcitabine and nab-paclitaxel, to assess safety and tolerability and time-to-event endpoints.

Вмешательства

• Препарат Olaptesed pegol
  400 mg per week as continous infusion until progression or intolerable toxicity
• Препарат Pembrolizumab
  200 mg every 3 weeks as i.v. infusion until progression or intolerable toxicity or a maximum of 35 administrations
