The proposed all-stock merger of troubled Acelyrin with Alumis, first announced on 6 February, will go forward, Acelyrin said 4 March, stating it will decline an unsolicited acquisition offer from Tang Capital-backed Concentra Biosciences that it received on 20 February. The Concentra bid would not result in a superior offer compared to the Alumis combination, Acelyrin said, adding that it expects the merger to close in Q2.
