What is the purpose of this trial?

This trial explores the effectiveness and safety of two drugs, adagrasib (Krazati or MRTX-849) and pembrolizumab (Keytruda), either alone or combined, for treating advanced non-small cell lung cancer (NSCLC) with a KRAS G12C mutation. The Phase 2 part tests the drugs' effectiveness in patients with varying levels of PD-L1, a protein that can influence the immune response to cancer. The Phase 3 part compares the combination of both drugs to pembrolizumab alone for patients whose cancer cannot be surgically removed and have higher PD-L1 levels. This trial may suit those diagnosed with advanced NSCLC with the KRAS G12C mutation who have not received prior treatments for this condition. As a Phase 2 and Phase 3 trial, it measures initial effectiveness and represents the final step before FDA approval, offering a chance to contribute to groundbreaking cancer treatment advancements.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it excludes those who have had prior systemic treatment for advanced NSCLC. It's best to discuss your current medications with the trial team.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that adagrasib, also known as MRTX849, is generally safe for patients with non-small cell lung cancer (NSCLC) who have a specific genetic mutation called KRAS G12C. Earlier studies found no new safety issues, and the safety information aligned with existing knowledge about the drug, indicating no unexpected side effects.

When combined with pembrolizumab, a common lung cancer treatment, adagrasib also appears safe. Side effects are typically mild and manageable. Studies have demonstrated that this combination is effective regardless of PD-L1, a protein involved in the body's immune response.

In summary, current research indicates that both adagrasib alone and with pembrolizumab are safe. The treatment is well-tolerated, with most individuals not experiencing serious side effects. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about adagrasib in combination with pembrolizumab for lung cancer because it targets a specific mutation known as KRAS G12C, which is present in some lung cancer tumors. Most current treatments, like chemotherapy and immunotherapy, don't specifically target this mutation. Adagrasib is designed to block the KRAS G12C protein, potentially stopping cancer cell growth more effectively. Furthermore, when combined with pembrolizumab, an immune checkpoint inhibitor, it might enhance the immune system's ability to fight cancer. This dual approach could offer a new, more precise method for tackling lung cancer compared to standard treatments.

What evidence suggests that this trial's treatments could be effective for lung cancer?

Research has shown that adagrasib, one of the treatments studied in this trial, helps delay cancer progression when used alone. Studies found that patients experienced an average of 6.8 months before their cancer advanced. In this trial, some participants will receive adagrasib combined with pembrolizumab, another cancer treatment. Early findings suggest that this combination may extend patients' lives, particularly those with certain genetic changes in their cancer. This treatment is effective regardless of PD-L1 levels, a protein that can influence cancer growth. Overall, these treatments show promise for treating advanced non-small cell lung cancer (NSCLC) with a specific KRAS G12C mutation. ^{1 2 6 7 8}

My NSCLC is inoperable or has spread, with a KRAS G12C mutation.

You have a measurable disease according to RECIST criteria.

Exclusion Criteria

I have had treatments like chemotherapy or immunotherapy for advanced lung cancer.

I don't have large untreated brain lesions, brainstem lesions, high steroid use for brain symptoms, frequent seizures, or worsening neurological symptoms due to brain lesions.

I have active cancer spread to my brain.

Published Research Related to This Trial

Pembrolizumab is a safe and effective immune checkpoint inhibitor that targets the PD-1 receptor, currently approved for treating advanced melanoma and metastatic non-small cell lung cancer (NSCLC).

Ongoing studies are exploring the potential of pembrolizumab in combination with other treatments for lung cancer and other cancer types, while also investigating biomarkers that may predict patient response to this therapy.

In a phase II trial involving 15 patients with resectable non-small cell lung cancer (NSCLC), neoadjuvant treatment with pembrolizumab showed a major pathologic response in 27% of patients, indicating promising antitumor activity before surgery.

The treatment was found to be feasible and safe, with only 33% of patients experiencing moderate adverse events, and no postoperative mortality, suggesting that pembrolizumab does not compromise surgical outcomes.

In a Phase 2 study involving 35 patients with non-small cell lung cancer, neoadjuvant pembrolizumab was found to be safe and well tolerated, with only one surgery delay due to thyroiditis and no mortality within 90 days post-surgery.

The study showed a high rate of R0 resection (88%) and a major pathologic response in 28% of patients, indicating that pembrolizumab may be more effective than standard neoadjuvant chemotherapy in this setting.
