FDA OKs Vyloy for Rare Gastric Cancer

FDA has approved an Astellas Pharma BLA for Vyloy (zolbetuximab-clzb) in combination with fluoropyrimidine- and platinum-containing chemotherapy for the first-line treatment of adults with locally advanced unresectable or metastatic human epidermal growth factor receptor 2-negative gastric or gastroesophageal junction adenocarcinoma whose tumors are claudin 18.2 positive as determined by an FDA-approved test.

The approval was based on data from the Phase 3 SPOTLIGHT and GLOW clinical trials. Both trials met their progression-free survival primary endpoint, as well as overall survival, which was a key secondary endpoint, according to the company. “Across the SPOTLIGHT and GLOW trials, the most common all-grade treatment-emergent adverse events reported in the Vyloy treatment arms were nausea, vomiting and decreased appetite,” it says.
