Brief Summary:
This is a multicenter, open-label, Phase 1, first-in-human, dose-escalation study designed to assess the safety, tolerability and define the RP2D of MT-303 alone (Module 1) and in combination with Atezo/Bev (Module 2) in participants with advanced hepatocellular carcinoma expressing GPC3.
Detailed Description:
Participants will be enrolled into one of two treatment modules:
* Module 1 (Monotherapy): Participants will receive MT-303.
* Module 2 (Combination therapy): Participants will receive MT-303 in combination with atezolizumab + bevacizumab (Atezo/Bev).
In Module 1 (Monotherapy), participants will receive MT-303 across five dose-escalation cohorts and in Module 2 (Combination therapy), participants will receive MT-303 in combination with Atezo/Bev across five dose-escalation cohorts.
Additional cohorts in both modules may be scheduled based on emerging safety and PK data.
Participants will be sequentially enrolled into Cohorts 1 through 5. Both modules will be enrolled concurrently, with Module 2 dosing beginning at one dose level below the known safe dose in Module 1. Safety Review Committee decisions will be informed by all available safety data from Modules 1 and 2.
