FRANKFURT, Germany & GANZHOU, China, May 26, 2026–(BUSINESS WIRE)–Merz Therapeutics GmbH and Jiangxi Kvvit Pharmaceutical Co. Ltd. today announced that the companies have entered into an exclusive license and collaboration agreement regarding INBRIJA® (levodopa inhalation powder) and its proprietary inhalation device for the intermittent treatment of episodic motor fluctuations (OFF episodes) in adult patients with Parkinson’s disease (PD) treated with a levodopa/dopa-decarboxylase inhibitor in mainland China, Hong Kong and Macao.
Under the agreement, Merz will supply INBRIJA® and retain responsibility for global product quality and key regulatory activities.
