Conditions: Solid Tumor, Adult
Interventions: ICT01, Proleukin Injectable Product, Pembrolizumab injection
Countries: France, Germany, United Kingdom
This is a phase I/IIa, two-part, open-label study to characterize the safety, tolerability, pharmacodynamics, and antitumor activity of ICT01 in combination with LDSC IL-2 in patients with advanced-stage solid tumors. Part 1 will be a dose escalation of IV ICT01 administered on the first day of every 21-day cycle (CnD1) to patients with advanced-stage solid tumors in combination with LDSC IL-2 (Proleukin®) administered daily on days 1-5 of cycles 1-3 (C1-3D1-5). Objectives of part 1 are to characterize the safety of the combination regimen and determine the RP2D for Part 2. Part 2 will comprise a maximum of 2 indications and 2 combination dosing regimens of ICT01 +LDSC IL-2, which will be supported by statistical power calculations once the indications are selected. The final regimen will be ICT01 + LDSC IL-2 + Pembrolizumab on a Q3W cycle. The primary objective of Part 2 is to demonstrate the efficacy of the combination regimen based on RECIST1.1 in one or more solid tumor indications.
