Apricus Biosciences Announces Outcome of Vitaros™ End-of-Review Meeting with FDA
FDA Confirms Vitaros Regulatory Pathway
Company Seeking Partner to Develop Vitaros in U.S.
Company Evaluating Strategic Alternatives
SAN DIEGO, April 16, 2018 (GLOBE NEWSWIRE) -- Apricus Biosciences, Inc. (Nasdaq:APRI), a biopharmaceutical company advancing innovative medicines in urology and rheumatology, today announced the outcome of its end-of-review meeting with the U.S. Food and Drug Administration (FDA) on the New Drug Application (NDA) for Vitaros™ (alprostadil, DDAIP.HCl), a topical cream for the treatment of erectile dysfunction.
The preliminary end-of-review meeting minutes support a plan to address issues cited by the FDA in its February 15, 2018 Complete Response Letter (CRL) for the Vitaros NDA. Specifically, the FDA confirmed during the meeting that the company should develop a new Vitaros formulation that reduces the concentration of DDAIP.HCl from 2.5% to 0.5% in order to address the tumor promotion and partner transference safety concerns noted in the CRL. The FDA also confirmed that two new Phase 3 clinical efficacy trials with the reformulated product should be conducted prior to resubmitting the NDA and that the trials should include an assessment of the potential risk of enhanced sexually transmitted infections with the new formulation. In addition, the FDA requested certain pharmacokinetic assessments that we expect can be completed as part of the requested Phase 3 program and any additional clinical or commercial safety data generated prior to a resubmission. Lastly, the FDA stated that the Chemistry, Manufacturing and Control (CMC) section in the resubmission will need to be updated with data generated during development of the new formulation.
The FDA previously issued a CRL for the Vitaros NDA, indicating that it could not approve the NDA for Vitaros in its present form, identifying deficiencies related to CMC and whether the modest treatment effect of Vitaros outweighed certain safety concerns specific to the 2.5% concentration of DDAIP.HCl contained in the current formulation.
“While we are pleased that the FDA has outlined a clear regulatory pathway for Vitaros, which we believe provides a path to approval in the U.S., the cost and timeline associated with a reformulation effort and completing additional phase 3 clinical trials exceeds our current resources and our ability to raise additional capital. Therefore, we have initiated discussions with interested parties for the U.S. Vitaros rights to enable its continued development and potential approval in exchange for financial terms commensurate with a development stage asset. In parallel, the Board of Directors has determined that Apricus should evaluate strategic alternatives or other business combinations, with the goal of maximizing shareholder value,” said Richard Pascoe, Chief Executive Officer.
