Results from the phase 2 KRYSTAL-1 trial led to the approval of adagrasib for patients with KRAS G12C–mutated non–small cell lung cancer by the European Commission.

In December 2022, adagrasib was granted accelerated approval by the FDA for KRAS G12C–mutated non–small cell lung cancer.

The European Commission has granted conditional marketing authorization to adagrasib (Krazati) for adult patients with KRAS G12C–mutated non–small cell lung cancer, according to a press release from Mirati.1

Results from the phase 2 KRYSTAL-1 trial (NCT03785249), which analyzed adagrasib at 600 mg orally twice daily, led to the agent’s approval. Patients were eligible if they had previously received treatment with a platinum-based regimen and an immune checkpoint inhibitor.

“This is a meaningful day for patients living with this difficult-to-treat cancer in the European Union as we can now offer a differentiated and potentially best-in-class therapeutic option to this underserved population,” Charles Baum, MD, PhD, founder, president, and chief executive officer, Mirati Therapeutics, Inc, said in the press release.

Investigators of the phase 1b portion of the KRYSTAL-1 trial identified enduring responses and intracranial activity for the aforementioned patient population.2 The intracranial objective response rate was 42.0% (95% CI, 20.3%-66.5%), with 3 patients achieving compete responses and 5 having partial responses.

In December 2022, adagrasib was granted accelerated approval by the FDA.3 At the time, Alexander I. Spira, MD, PhD, FACP, a medical oncologist and co-director of the Virginia Cancer Specialists Research Institution, and director of the Thoracic and Phase I Program and clinical assistant professor at Johns Hopkin, commented on the approval in an interview with CancerNetwork®, saying, “We already have sotorasib [Lumakras] readily approved, but [adagrasib and sotorasib] do have slightly different toxicity profiles. It's always good to have more than one class because some people do tolerate one better than the other.”
