The Food and Drug Administration (FDA) has granted accelerated approval to Krazati (adagrasib) for the treatment of adults with KRASG12C-mutation locally advanced or metastatic non-small cell lung cancer (NSCLC), as determined by an FDA approved test, who have received at least 1 prior systemic therapy.

Krazati is a highly selective and potent oral small molecule inhibitor of KRASG12C. The accelerated approval was based on data from the open-label registration-enabling cohort of the phase 2 KRYSTAL-1 study ( Identifier: NCT03785249), which evaluated adagrasib in 112 adults with NSCLC harboring the KRASG12C mutation following prior systemic therapy. Patients received adagrasib 600mg orally twice a day until disease progression or unacceptable toxicity.

After a median follow-up of 9 months, results showed an objective response rate of 43% (95% CI, 34-53) and a disease control rate of 80% (95% CI, 71-87) in the intent-to-treat population, based on central independent review. The median duration of response (DOR) was 8.5 months (95% CI, 6.2-13.8) with 58% of patients having a DOR lasting at least 6 months.

The most common adverse reactions reported with adagrasib were diarrhea, nausea, fatigue, vomiting, musculoskeletal pain, hepatotoxicity, renal impairment, dyspnea, edema, decreased appetite, cough, pneumonia, dizziness, constipation, abdominal pain, and QTc interval prolongation. Laboratory abnormalities included decreased lymphocytes, increased aspartate aminotransferase, decreased sodium, decreased hemoglobin, increased creatinine, decreased albumin, increased alanine aminotransferase, increased lipase, decreased platelets, decreased magnesium, and decreased potassium.

Krazati is supplied as 200mg tablets in 120- and 180-count bottles. The product is expected to be available immediately.

The FDA has also approved the Qiagen therascreen KRAS RGQ PCR kit (tissue) and the Agilent Resolution ctDx FIRST Assay (plasma) as companion diagnostics for Krazati. The tumor tissue should be tested if no mutation is detected in a plasma specimen.
