Phase I/II Study: Allogeneic NK-cell Therapy With Chemotherapy for Post-Surgery PDA or Cholangiocarcinoma Patients

Recruiting now · Phase 1/Phase 2

Conditions studied: Pancreatic Carcinoma Stage II, Cholangiocarcinoma Resectable

In brief

This is a phase I/II study which intends to characterize the safety, tolerability, and preliminary efficacy of Allogeneic Magicell-NK infusion in PDA or cholangiocarcinoma patients after surgery. Subjects will receive a total of 6 intravenous (IV) infusions of the IP on the 11th day of each chemotherapy cycle. A total of 6 cycles of IP infusions are planned. The phase I part of the study is a first-in-human phase I trial of Allogeneic Magicell-NK and is therefore designed in an open-label, dose-escalation manner. A standard 3+3 design will be employed to assess the safety profile of Allogeneic Magicell-NK and to determine the MTD/MFD. Two dose cohorts are planned: the starting dose is 10 × 10\^8 cells (Cohort 1), and escalates to 20 × 10\^8 cells (Cohort 2). The phase II part of the study is designed as an open-label, two-arm, randomized clinical trial comparing the combination of SLOG and Allogeneic Magicell-NK with SLOG alone when used as adjuvant therapy following resection for PDA or Cholangiocarcinoma. Approximately 30 subjects will be randomized at a 2:1 ratio between the two arms: Arm 1: SLOG and Allogeneic Magicell-NK (20 subjects); Arm 2: SLOG alone (10 subjects). Subjects will then receive 12 weeks of SLOG chemotherapy with or without Allogeneic Magicell-NK infusion.
