ASP Acerus Pharmaceuticals Corporation

Acerus Pharmaceuticals Corporation (TSX:ASP, OTCQB:ASPCF), a specialty pharmaceutical company focused on the commercialization of novel prescription products in Men’s Health, today announced that it has entered into a three-year agreement with Amneal Pharmaceuticals Inc. (“Amneal”) to co-promote NATESTO in the U.S. Endocrinology segment, leveraging the company’s extensive relationships with Endocrinology healthcare providers. Amneal will promote NATESTO through its 50+ sales representatives in a P2 position.

Under the terms of the agreement, Amneal will sell NATESTO to the company’s existing Endocrinology targets through June 30, 2024. In compensation for its marketing efforts, Amneal will receive a commission for most of the net profits attributed to Endocrinology targets in the three active promotional years, with Acerus retaining a low double-digit percentage of such net profits during the active promotion period. Amneal will also receive a three-year trailing royalty following the active promotion period, with compensation to Amneal decreasing from a majority of the net profits to a minority of the net profits.

“This co-promotion agreement significantly expands our NATESTO footprint in the U.S. by leveraging Amneal’s established relationships in the Endocrinology segment,” said Ed Gudaitis, President and Chief Executive Officer of Acerus. “The partnership will allow our Specialty Sales Representatives to expand their reach in the Urology segment while adding high-prescribing PCPs across their covered geographies. We have been encouraged by the increasing interest in NATESTO among specialists and are very excited to be partnering with Amneal to accelerate that growth through the combined efforts of more than 70+ speciality sales representatives.”
