Ropes & Gray advised Parma, Italy-based biopharmaceutical company Chiesi Group in a global strategic collaboration with Gossamer Bio to develop and commercialize Gossamer’s pulmonary arterial hypertension treatment seralutinib. The transaction was announced on May 6.
Under the agreement, Gossamer will lead the global development of seralutinib in pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD). Gossamer will receive $160 million in development reimbursement payment and is eligible to receive up to $146 million in regulatory and $180 million in sales milestones.
