A Study to Investigate Safety and Tolerability of TransCon IL-2 β/γ Alone or in Combination with Pembrolizumab, TransCon TLR7/8 Agonist, or other Anticancer Therapies in Adult Participants with Locally Advanced or Metastatic Solid Tumor Malignancies
EU CTIS ID: 2023-509143-27-00
What this study is testing
The main objective of Part 1 and 2 was to evaluate the safety and tolerability, and define the Maximum Tolerated Dose (MTD) and Recommended Phase 2 Dose (RP2D) of TransCon IL-2 β/γ alone or in combination with pembrolizumab. The main objective of Part 3 and Part 4 is to evaluate the safety and tolerability of TransCon IL-2 β/γ at RP2D as monotherapy and in combination with pembrolizumab, standard of care (SOC) chemotherapy, or TransCon TLR7/8 Agonist, or in combination with pembrolizumab and SOC chemotherapy or in combination with SOC trastuzumab or SOC trastuzumab emtansine (T-DM1)
