Novavax Inc. to Pursue Accelerated Approval Pathway for Licensure of NanoFlu™​​​​​​ Vaccine Candidate

On Thursday, June 27, 2019, Novavax Inc. announced plans to use the accelerated approval pathway for licensure of NanoFlu™, its nanoparticle seasonal influenza vaccine candidate. A phase 3 clinical trial is planned for fall 2019 with topline data expected in the first quarter of 2020.

The FDA made the pathway available to Novavax in a recent letter, according to a press release.

“NanoFlu’s encouraging results observed in prior clinical trials, which demonstrated improved immune responses against licensed comparators, provide us confidence in the future success of the Phase 3 clinical trial,” Gregory M. Glenn, MD, president of Research and Development of Novavax, said in a statement. “The accelerated approval pathway allows us to potentially obtain U.S. licensure more expeditiously, and ideally, deliver a greatly needed improved flu vaccine, which could reduce the tremendous medical and economic burden of influenza.”

Verrica Pharmaceuticals Announces Positive Topline Results in Phase 2 Clinical Trial of VP-102 for Treatment of Common Warts

On Wednesday, June 26, 2019, Verrica Pharmaceuticals announced positive topline results from its COVE-1 phase 2 open label clinical study of VP-102 for the treatment of verruca vulgaris.

The study evaluated the safety and efficacy of VP-102 in 2 cohorts of subjects with up to 6 warts. Cohort 1 was conducted at a single site with 21 subjects age 2 years and older receiving up to 4 treatments with VP-102 at least 14 days between treatments with longer treatment intervals allowed at the discretion of the investigator depending on a specific subject’s clinical response. Cohort 2 was conducted at 4 sites with 35 subjects age 12 years and older receiving up to 4 treatments with VP-102 every 21 days.

A total of 51% of subjects in cohort 2 achieved complete clearance of all treatable warts, and the treatment was well-tolerated with no serious adverse events reported.

“This is exciting news for Verrica and our proprietary cantharidin product. Positive Phase 2 data of VP-102 for the treatment of common warts, after the successful Phase 3 results achieved with VP-102 for molluscum contagiosum, further increases our confidence in the broad clinical utility and large market potential of our lead product,” Ted White, president and Chief Executive Officer of Verrica, said in a press release. “We are progressing the development of VP-102 for a broad range of skin diseases. We intend to request an ‘End of Phase 2’ meeting with the FDA for the treatment of common warts, and remain on track to submit an NDA for the treatment of molluscum contagiosum later this year.”
