Hengrui Pharma has announced that it has entered into agreements with GSK plc to develop up to 12 innovative medicines, adding significant value to the globalisation strategy of Hengrui and significant new growth opportunities to GSK beyond 2031.

The programmes were selected to complement GSK's extensive Respiratory, Immunology and Inflammation (RI&I) and Oncology pipeline, and assessed for their potential best- or first-in-class profiles. GSK will pay USD 500 million in upfront fees across the agreements, said the company in a statement.

The agreements include an exclusive worldwide license (excluding mainland China, Hong Kong SAR, Macau SAR and Taiwan region) for a potential best-in-class, PDE3/4 inhibitor (HRS-9821) in clinical development for the treatment of chronic obstructive pulmonary disease (COPD) as an add-on maintenance treatment, irrespective of background therapy. The addition of HRS-9821 supports GSK's ambition to treat patients across the widest spectrum of COPD by including those who face continued dyspnoea (shortness of breath) or who are unlikely to receive inhaled corticosteroids or biologics, based on their disease profile.

HRS-9821 has demonstrated potent PDE3 and PDE4 inhibition, leading to increased bronchodilation and anti-inflammatory effects in early clinical and preclinical studies. In addition, HRS-9821 provides the opportunity for a convenient dry-powder inhaler (DPI) formulation that strategically fits GSK's established inhaled portfolio.

The agreements also include a scaled collaboration to generate up to 11 programmes in addition to HRS-9821, each with its own financial structure. Hengrui Pharma will lead the development of these programmes up to completion of phase I trials, including patients outside of China. GSK will have the exclusive option to further develop and commercialise each programme worldwide (excluding mainland China, Hong Kong SAR, Macau SAR and Taiwan region), at the end of phase I or earlier at GSK's election as well as certain programme substitution rights.

Frank Jiang, Executive Vice President and Chief Strategy Officer of Hengrui Pharma, said, “This strategic collaboration with GSK marks yet another significant milestone in Hengrui's globalisation journey and our mission to innovate and deliver higher-quality, cutting-edge therapies for patients worldwide. GSK brings additional R&D expertise, a robust global clinical network, and broad regulatory capabilities that will accelerate our PDE3/4 inhibitor as well as an array of other innovative therapy programs to overseas markets, potentially delivering breakthrough treatments to patients globally.”

Tony Wood, Chief Scientific Officer, GSK said, “We're delighted to announce these exciting agreements with Hengrui Pharma which complement our already-extensive pipeline. This deal reflects our strategic investment in programmes that address validated targets, increasing the likelihood of success, and with the option to advance those assets with the greatest potential for patient impact.”

The collaboration enables scale and speed to proof-of-concept to develop up to 11 additional innovative medicines. It benefits from GSK's therapy area expertise, deep understanding of disease biology, clinical development capability and global commercial scale with Hengrui Pharma's early discovery engine, platform technologies, extensive pre-clinical pipeline of high-value programmes and speed of clinical evaluation.
