Heron Therapeutics Announces Submission of HTX-019 NDA for the Prevention of Postoperative Nausea and Vomiting to FDA
The NDA filing includes data demonstrating the bioequivalence of HTX-019 32 mg as a 30-second IV injection to oral aprepitant 40 mg, supporting its efficacy for the prevention of PONV. Results also showed HTX-019 was well-tolerated with a similar safety profile compared to oral aprepitant. Because HTX-019 is administered as an IV injection, it provides convenient, rapid, consistent, and reliable exposure in all patients and overcomes the need to take the oral formulation 1 to 3 hours before anesthesia. The HTX-019 injectable emulsion formulation intended for PONV prevention is identical to the approved CINVANTI® (aprepitant) injectable emulsion formulation for prevention of chemotherapy-induced nausea and vomiting (CINV).
Despite advances in postoperative care, nausea and vomiting has remained a challenge for many patients undergoing surgery. There are approximately 65 million diagnostic and surgical procedures at risk of resulting in PONV in the
"In a recent Cochrane Meta-Analysis, aprepitant was found to be the most effective agent for PONV prevention with activity similar to two-drug combinations. In fact, the use of oral aprepitant has grown by almost 80% in the past three years without any promotional efforts. Our IV formulation is designed to directly deliver the active form of the drug, aprepitant, to patients over 30 seconds so it can take effect much more quickly than when taken orally," said
"There remains an important unmet need for effective and convenient products for PONV prevention," said
About HTX-019 for PONV
HTX-019 is an IV injectable emulsion formulation designed to directly deliver aprepitant, the active ingredient in EMEND® (aprepitant) capsules, which is the only substance P/neurokinin-1 receptor antagonist to be approved in the U.S. for the prevention of postoperative nausea and vomiting (PONV) in adults. The FDA-approved dose of oral EMEND is 40 mg for PONV prevention, which is given within 3 hours prior to induction of anesthesia for surgery. In a Phase 1 clinical trial, 32 mg of HTX-019 as a 30-second IV injection was demonstrated to be bioequivalent to oral aprepitant 40 mg. The NDA for HTX-019 for PONV was submitted in
About CINVANTI for Chemotherapy-Induced Nausea and Vomiting (CINV) Prevention
CINVANTI, in combination with other antiemetic agents, is indicated in adults for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of highly emetogenic cancer chemotherapy (HEC) including high-dose cisplatin as a single-dose regimen, delayed nausea and vomiting associated with initial and repeat courses of moderately emetogenic cancer chemotherapy (MEC) as a single-dose regimen, and nausea and vomiting associated with initial and repeat courses of MEC as a 3-day regimen. CINVANTI is an IV formulation of aprepitant, an NK1 RA. CINVANTI is the first IV formulation to directly deliver aprepitant, the active ingredient in EMEND® capsules. Aprepitant (including its prodrug, fosaprepitant) is the only single-agent NK1 RA to significantly reduce nausea and vomiting in both the acute phase (0–24 hours after chemotherapy) and the delayed phase (24–120 hours after chemotherapy). The FDA-approved dosing regimens included in the U.S. prescribing information for CINVANTI include 100 mg or 130 mg administered as a 30-minute IV infusion or a 2-minute IV injection.
