New combo attack targets hard-to-treat KRAS G12C cancers
NCT ID NCT05358249
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new drug called JDQ443, which targets a specific cancer-driving mutation (KRAS G12C), in combination with other drugs (trametinib, ribociclib, or cetuximab). The trial enrolls about 74 people with advanced solid tumors (like lung or colorectal cancer) that have this mutation and have already tried standard treatments. The goal is to find safe doses and see if these combinations can shrink tumors or control the disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- JDQ443 (a KRAS G12C inhibitor) combined with trametinib, ribociclib, or cetuximab
- What this could lead to
- If successful, this could point toward new combination treatments that shrink or control advanced KRAS G12C cancers like lung and colorectal cancer.
- What could go wrong
- This is an early-phase trial (phase 1b/2) with only 74 participants, so results may not apply to all patients. Combinations may cause significant side effects or fail to improve outcomes.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: Dose Escalation: \- Patients with advanced (metastatic or unresectable) KRAS G12C mutant solid tumors who have received standard of care therapy or are ineligible to receive such therapy. Phase II: * Patients with advanced (metastatic or unresectable) KRAS G12C mutant non-small cell lung cancer who have received platinum-based chemotherapy regimen and immune checkpoint inhibitor therapy, unless patient was ineligible to receive such therapy * Patients with advanced (metastatic or unresectable) KRAS G12C mutant colorectal cancer who have received fluropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy, unless patient was ineligible to such therapy. All patients: * ECOG performance status of 0 or 1. * Patients must have a site of disease amenable to biopsy and be a candidate for tumor biopsy according to the treating institution's guidelines. Exclusion Criteria: * Tumors harboring driver mutations that have approved targeted therapies, with the exception of KRAS G12C mutations * Prior treatment with a KRAS G12C inhibitor is excluded for patients in a subset of groups in Phase II. * Active brain metastases, including symptomatic brain metastases or known leptomeningeal disease * Clinically significant cardiac disease or risk factors at screening * Insufficient bone marrow, hepatic or renal function at screening Other protocol-defined inclusion/exclusion criteria may apply
