Detaljert beskrivelse

This is an open-label, multicenter Phase Ib/II clinical trial to evaluate the safety, tolerability, and preliminary anti-tumor efficacy of oral GFH276 in combination with cetuximab or standard chemotherapy in adult patients with locally advanced or metastatic RAS-mutated solid tumors and pancreatic ductal adenocarcinoma (PDAC).

Participants will be enrolled into three treatment arms with different combination regimens.

In the Phase Ib stage, dose escalation of GFH276 will be performed in each combination arm to identify the optimal recommended Phase 2 dose (RP2D) based on dose-limiting toxicity (DLT) and the overall safety profile. After RP2D determination, Phase II expansion cohorts will enroll eligible patients to further evaluate the anti-tumor efficacy and long-term safety of each combination regimen. Study-related assessments will include tumor imaging, laboratory tests, adverse event monitoring, and pharmacokinetic sampling throughout the treatment period.

Participants will continue their assigned study treatment until confirmed disease progression, intolerable toxicity, withdrawal of consent, or study closure.
