Alkermes Commences Arbitration Related to License Agreements with Janssen Pharmaceutica


DUBLIN, April 19, 2022 /PRNewswire/ --Alkermes (Nasdaq: ALKS) today announced that it commenced binding arbitration proceedings in respect of two license agreements with Janssen Pharmaceutica N.V.  ("Janssen"), a subsidiary of Johnson & Johnson. Under these agreements, Janssen received access and rights to Alkermes' small particle pharmaceutical compound technology, known as NanoCrystal® Technology, which enabled a number of successful products, such as INVEGA SUSTENNA®, INVEGA TRINZA®, INVEGA HAFYERA® and CABENUVA®. Janssen partially terminated the agreements in the United States effective as of February 2022. 

The purpose of the arbitration is to settle, among other things, whether, notwithstanding its partial termination of the agreements, Janssen has a continuing obligation to pay royalties on sales in the United States of products developed under the agreements. Janssen has refused to pay any royalties required by the agreements in the United States since the effective date of the partial terminations. Alkermes strongly disagrees with Janssen's position and contends that it continues to owe royalties. Alkermes remains committed to enforcing its contractual rights and addressing any unauthorized use of its intellectual property. 

Following receipt of the notices of partial termination, Alkermes triggered dispute resolution provisions in the license agreements. The company has engaged with Janssen in an effort to come to a mutually agreeable settlement. No resolution has been achieved. Alkermes remains open to a mutually agreeable resolution. 

Under the agreements, the arbitration will be conducted pursuant to the Institute for Conflict Prevention and Resolution (CPR) Rules for Non-Administered Arbitration before a panel of three arbitrators. The arbitration will be confidential, subject to the parties' disclosure obligations under applicable law. Other than pursuant to these obligations, Alkermes does not intend to comment or provide additional information regarding the arbitration until an order on the merits or other material order is issued in the arbitration or the arbitration is otherwise concluded.
