The biopharmaceutical company reported a quarterly net loss of $1.29 per share, which was wider than the $1.09 loss per share anticipated by analysts polled by FactSet.

Concurrently, the company announced a strategic restructuring plan, including a 10% reduction of its workforce affecting approximately 130 employees, as it aims to chart a path to profitability by 2027.
