ASP Acerus Pharmaceuticals Corporation

Acerus Pharmaceuticals Corporation (the “Company” or “Acerus”) (TSX:ASP, OTCQB:ASPCF) today announced that, on June 15, 2021, it prevailed at a preliminary issue trial in which Recipharm Limited (“Recipharm”) alleged that Acerus’ claim for damages was barred by the terms of the companies’ manufacturing contract. In agreeing with Acerus that its claim for damages was not barred, the Commercial Court of London directed the matter to proceed to a full trial in the coming months. Recipharm has asked for permission to appeal the court’s decision.

"This is an important step forward in Acerus’ effort to hold Recipharm accountable for its contractual breaches,” said Ed Gudaitis, President and Chief Executive Officer of Acerus. “Manufacturers in the pharmaceutical industry rely on contract manufacturing organizations like Recipharm to ensure that patients have access to the medicines they need. We are pleased with the court’s decision and are confident that the appeal process will resolve this issue in our favor."

On June 18, 2020, Acerus announced it had commenced litigation against Recipharm, a wholly-owned subsidiary of Recipharm AB, in the Commercial Court of London. Acerus alleged that the suspension of Recipharm’s manufacturing license in August 2018 was a violation of its contractual obligations and led to a shortage of Estrace® in Canada.
