The agreement covers all member states in EEA, UK and Switzerland.

The total deal value, including upfront and regulatory and commercialization milestone payments is EUR 220 million, which includes an upfront payment of EUR 13 million and a near-term milestone of EUR 5 million in 2026. Cinclus Pharma is also entitled to tiered double-digit royalties on net sales in Europe, starting in the high-teens and exceeding 20% at the highest tier levels.

“We are particularly excited given Zentiva’s commercial reach and operational strength across Europe. This alliance establishes a fully integrated set of capabilities covering everything necessary to bring linaprazan glurate to the market across Europe. The alliance benefits from world-leading expertise in gastroenterology-focused development, regulatory affairs, manufacturing and commercialization. This collaboration not only de-risks our path to European approval but also positions us to capture significant global value, particularly in the US market where we retain full commercial rights and see a substantial commercial opportunity,” says Christer Ahlberg, CEO of Cinclus Pharma.

Cinclus Pharma expects to initiate its first Phase III study with linaprazan glurate in Q3 2025.
