An arbitration tribunal issued a final award on July 6, 2026, declaring that Prime Medicine's PM647 candidate for Alpha-1 Antitrypsin Deficiency is within the agreement's Field and that the company did not breach its 2019 agreement with Beam Therapeutics. The tribunal denied Beam's requests for damages and injunctive relief and denied the remaining claims by both parties. The ruling removes a breach claim tied to a key development candidate, though the filing gives no financial figures.
