Aegis Therapeutics Announces Use of Intravail® in a Positive Phase 2 Study of DFN-02 for Acute Migraine

San Diego, California, UNITED STATES

SAN DIEGO, June 28, 2017 (GLOBE NEWSWIRE) -- Aegis Therapeutics announces positive Phase 2 results of DFN-02 using Intravail® technology. Dr. Reddy's Laboratories in collaboration with Promius Pharma, LLC (a wholly owned subsidiary of DRL) is developing DFN-02, a novel intranasal migraine treatment using Intravail for the acute treatment of adults with migraine with or without aura.  Promius Pharma will market the drug product once approved. 

In this multicenter, double-blind study ( # NCT02856802), episodic migraine patients were randomized to receive either DFN-02 or placebo to treat a migraine attack with a moderate or severe pain level. The primary endpoint was the proportion of subjects with migraine pain freedom at 2 hours postdose (2hPF).

A significantly higher proportion of subjects experienced 2-hour Pain Freedom with DFN-02 compared with placebo: 43.8% (n=48) versus 22.5% (n=40), P<0.05. DFN‑02 was also significantly better than placebo at alleviating patient-identified most bothersome symptom (MBS), from among nausea, photophobia, and phonophobia (70.7% versus 39.5% MBS free at 2 hours postdose; P<0.01). DFN-02 was well tolerated, with only 5 of 50 subjects reporting a mild or moderate adverse event.

According to Dr. Edward Maggio, Chief Executive Officer of Aegis Therapeutics, “We are very pleased to work with Dr. Reddy’s laboratories, a leading multinational pharmaceutical company, to develop this product for people with migraine”. 

According to Mr. Ralph Barry, Chief Business Officer of Aegis Therapeutics, “At present, more than a dozen other drugs employing Aegis Intravail® and ProTek® technologies have been reformulated for significantly improved performance by Aegis’ licensees, which include seven of the top 10 world’s largest pharmaceutical companies and two of the top 10 leading multinational generics companies, along with a host of public and private biotechnology companies.”

About DFN-02
