FDA Approves Heron’s Sustol for Treating Nausea
FDA has approved a Heron Therapeutics for Sustol (granisetron) extended-release injection, a serotonin-3 (5-HT3) receptor antagonist indicated in combination with other antiemetics in adults for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of moderately emetogenic chemotherapy (MEC) or anthracycline and cyclophosphamide combination chemotherapy regimens. The product uses Heron’s Biochronomer polymer-based drug delivery technology to maintain therapeutic levels of granisetron for five days and longer, covering both the acute and delayed phases of chemotherapy-induced nausea and vomiting (CINV).
The approval was more than three years in the making. In 3/2013, FDA issued a complete response letter for the drug, asking that the company refine a chemistry, manufacturing and controls product quality analytical test method, and address deficiencies identified during facility pre-approval inspections (see story).
The NDA included data from the MAGIC study, Heron’s multi-center, placebo-controlled, Phase 3 study involving more than 900 patients receiving highly emetogenic chemotherapy regimens. Data from an earlier Phase 3 study of more than 1,300 patients, which were previously submitted to the agency, demonstrated Sustol’s efficacy in preventing acute and delayed CINV associated with MEC regimens and acute CINV associated with HEC regimens, the company says.
