Acerus Pharmaceuticals Corporation (TSX: ASP, OTCQB: ASPCF) (“Acerus” or the “Company”), a specialty pharmaceutical company focused on the commercialization of novel prescription products in Men’s Health, today announced the signing of an agreement with Aytu BioPharma (f/k/a Aytu BioScience), whereby Acerus bought back all remaining rights to NATESTO in the U.S. that were not already returned to Acerus as part of the 2019 Amended and Restated Agreement with Aytu. Acerus launched promotional efforts to key Urology and Endocrinology specialists in August of 2020. Following early growth in the specialty segment, assuming full ownership of NATESTO fulfills Acerus’ mission to build and leverage a robust commercial business unit in the U.S.

Acerus has agreed to purchase these rights from Aytu for $7.5 million USD, paid evenly over 30 monthly installments and will assume all product responsibilities following the effective date. Acerus expects these payments to be funded from net revenues generated by NATESTO. In addition to Acerus detailing to Specialty HCPs, Acerus will now gain full distribution rights and full reporting of net revenues. To ensure a smooth transition, Aytu has agreed to assist Acerus throughout a 120-day Transition period from the effective date. During this transition period, Aytu will continue to provide distribution of NATESTO under the terms of the existing License and Supply Agreement.

“Purchasing the full rights for NATESTO in the U.S. allows us to continue our transformation into becoming a leading innovative specialty pharmaceutical company,” said Ed Gudaitis, President and Chief Executive Officer of Acerus. “Owning distribution in the U.S. is a key step in our transformation, providing us with the opportunity and flexibility to maximize the value and clinical differentiation of NATESTO.”
