Imfinzi OK’d for Resectable Lung Cancer
FDA has approved AstraZeneca’s Imfinzi (durvalumab) with platinum-containing chemotherapy as neoadjuvant treatment that is followed by single-agent durvalumab as adjuvant treatment after surgery for adults with resectable (tumors greater than 4 cm or node positive) non-small cell lung cancer (NSCLC). The drug is intended for use in those with no known epidermal growth factor receptor mutations or anaplastic lymphoma kinase rearrangements, according to an FDA release.
Approval was based on date from the company’s AEGEAN (NCT03800134) trial in 802 patients with previously untreated and resectable squamous or non-squamous NSCLC (Stage IIA to select Stage IIIB), the agency says. Patients were administered either durvalumab or placebo, with platinum-based chemotherapy, every three weeks for up to four cycles followed by either continued single-agent durvalumab or placebo for up to 12 cycles (adjuvant treatment), it says.
The trial’s efficacy outcome measures were event-free survival (EFS) and pathological complete response (pCR). FDA says median EFS was not reached, and the pCR rate was 17% and 4.3% in the durvalumab and placebo arms, respectively. “At the time of the prespecified interim analyses, overall survival (OS) was not formally tested for statistical significance; however, a descriptive analysis revealed no clear detriment,” it adds.
