Lung cancer drug adagrasib: which dose works best?
NCT ID NCT05853575
First seen Jun 27, 2026 · Last updated Aug 14, 2026 · Updated 3 times
Summary
This phase 2 study compares two dosing schedules of the targeted drug adagrasib (Krazati) in 200 adults with advanced non-small cell lung cancer that has a specific KRAS G12C mutation. Participants have already tried chemotherapy and immunotherapy. The goal is to see if a lower dose taken with food works as well as the standard higher dose, potentially reducing side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Adagrasib (Krazati), a targeted cancer drug
- What this could lead to
- If successful, this could identify a more effective or better-tolerated dosing schedule for adagrasib in KRAS G12C lung cancer, improving treatment options.
- What could go wrong
- This is a phase 2 trial with only 200 participants, so results may not apply to all patients. The drug may cause side effects, and the lower dose might be less effective.

Key Inclusion Criteria: * Are at least 18 years old (or old enough to legally make their own treatment decisions, according to local laws). * Have advanced NSCLC or metastatic NSCLC (NSCLC that started in the lungs and then spread to other parts of the body) with the KRAS G12C mutation. * Have had previous treatment with 1) chemotherapy that included a drug called cisplatin or a drug called carboplatin and 2) a type of drug called an immune checkpoint inhibitor. * Have recovered from their prior treatment and blood tests are within a safe range. Key Exclusion Criteria: * Have had previous treatment with a drug that targets KRAS G12C. * Have cancer that can potentially be removed with surgery. * Patients with brain lesions are not eligible if 1) any untreated brain lesions are \> 2.0 cm in size 2) any brainstem lesions are present 3) ongoing steroid dosing \>10 mg daily prednisone (or equivalent) and 4) poorly controlled (\> 1/week) generalized or complex partial seizures or neurologic progression/instability due to brain lesions. * Have certain medical conditions or need to take certain medications that, in the opinion of a trial doctor, could make it unsafe for them to participate or difficult to complete the trial assessments, or are pregnant.
