Apricus Biosciences Receives FDA Clearance to Begin Clinical Trial of RayVa(TM) for Secondary Raynaud's Phenomenon Phase 2a Trial Expected to Commence Patient Enrollment in the Second Half of 2014 SAN DIEGO, May 12, 2014 (GLOBE NEWSWIRE) -- Apricus Biosciences, Inc. (Nasdaq:APRI), a pharmaceutical company focusing on the development and commercialization of novel therapeutics for men's and women's health, today announced that the U.S. Food and Drug Administration (FDA) has cleared the Company's Investigational New Drug (IND) application allowing the Company to initiate clinical testing of RayVa^™, Apricus' product candidate for the treatment of Raynaud's phenomenon. The Company expects to commence a Phase 2a clinical trial and begin enrollment in the second half of 2014. RayVa combines alprostadil, a vasodilator, with Apricus' proprietary permeation enhancer DDAIP.HCl, and is applied as an on-demand topical cream to affected extremities. In a nonclinical model, the Company demonstrated topical administration of alprostadil cream to cold-challenge statistically improved blood flow by 30 minutes relative to placebo, as measured by Laser Doppler. The improvement in blood flow was maintained out to 90 minutes post-challenge. "We are excited to bring our third product candidate into the clinic, expanding our development pipeline beyond sexual health, and leveraging our proprietary permeation enhancer technology, to address Raynaud's phenomenon secondary to scleroderma, a disease that affects an estimated 100,000 people in the United States^1," said Richard W. Pascoe, Chief Executive Officer. "Secondary Raynaud's phenomenon disproportionately affects women and currently has no approved therapy in the United States, representing an unmet medical need. Patients suffering from secondary Raynaud's phenomenon are typically treated by just over 4,500 rheumatologists in the United States^2, thus providing Apricus with a potential path to building a focused commercial organization in the future." The randomized, double-blind, placebo-controlled, Phase 2a trial is expected to enroll approximately fifty patients with Raynaud's phenomenon secondary to scleroderma. Each patient will receive applications of placebo and doses of RayVa, in a crossover design. This dose-ranging study will evaluate hemodynamics and temperature at the site of application in response to a cold challenge, as measured by Laser Doppler and thermography. Other endpoints include safety and pharmacokinetic assessments. The FDA has indicated that RayVa may qualify for priority review, given the unmet medical need and lack of approved products to treat secondary Raynaud's phenomenon. The FDA will determine if the RayVa New Drug Application qualifies for priority review following its submission, which could occur as early as 2017. About Raynaud's Phenomenon Raynaud's phenomenon is characterized by vasoconstriction in the hands, feet or other extremities, resulting in reduced blood flow and the sensation of pain, which can become severe. It is classified as either primary or secondary.Primary Raynaud's phenomenon, which is not associated with an underlying medical condition, refers to vasoconstriction associated with exposure to cold or stress.Primary Raynaud's phenomenon affects an estimated 3-5% of the US population, mostly women.^3Secondary Raynaud's phenomenon, with symptoms similar to primary Raynaud's phenomenon, is driven by an underlying medical condition, such as scleroderma, lupus or rheumatoid arthritis.^4There are an estimated 100,000 adult patients with scleroderma in the US^1, of which approximately 90% have secondary Raynaud's phenomenon^4.Overall, there are approximately 500,000 adult patients with secondary Raynaud's phenomenon in the US.^4,5 Approximately 80% of scleroderma patients are women.^6Both primary and secondary Raynaud's phenomenon disproportionately affects women.^7There is currently no approved therapy for Raynaud's phenomenon in the United States, representing an unmet medical need.
