Pharma Partners Gilead and LEO Pharma Forge Strategic Partnership to Advance Oral STAT6 Program for Inflammatory Diseases
Pharma Partners Gilead Sciences and LEO Pharma today announced a groundbreaking strategic partnership designed to accelerate the development and commercialization of LEO Pharma’s small molecule oral STAT6 (signal transducer and activator of transcription 6) inhibitors. These molecules have the potential to treat a variety of inflammatory diseases, offering an oral alternative to the injectable biologics currently used for managing such conditions. This collaboration highlights both companies’ commitment to improving the treatment landscape for chronic inflammatory diseases, with the potential to offer new options to patients suffering from conditions such as atopic dermatitis, asthma, and chronic obstructive pulmonary disease (COPD).
The Promise of STAT6 in Inflammatory Diseases
Pharma Partners STAT6 plays a crucial role in the immune system’s response to inflammatory diseases, particularly those mediated by T-helper cell type 2 (Th2) signaling. IL-4 and IL-13, the cytokines responsible for triggering the activation of STAT6, are known to contribute to the pathogenesis of a variety of inflammatory diseases, including common conditions such as atopic dermatitis, asthma, COPD, and several other Th2-mediated diseases. By targeting STAT6, scientists have the potential to disrupt this critical inflammatory pathway, offering a novel approach to treating patients with chronic conditions that are often difficult to manage.
Pharma Partners Research has shown that inhibiting the STAT6 pathway can effectively treat a broad range of inflammatory diseases. In addition, an oral formulation of these inhibitors would be a significant advancement, providing patients with an easier-to-administer alternative to current treatments that rely on injectable biologics. This shift could be particularly transformative for patients who require long-term treatment or face challenges with adherence to injectable regimens.
Details of the Partnership
Pharma Partners Under the terms of the strategic partnership, Gilead Sciences will acquire LEO Pharma’s complete portfolio of preclinical small molecule oral STAT6 inhibitors and targeted protein degraders. Gilead will take the lead on the further development of the oral STAT6 programs, advancing them through clinical trials and, eventually, commercialization. On the other hand, LEO Pharma will continue to lead the development efforts related to the potential topical formulations of STAT6 inhibitors for dermatological conditions.
The collaboration leverages the strengths of both companies: Gilead’s extensive expertise in the development and commercialization of innovative therapies, particularly in inflammation and immunology, and LEO Pharma’s strong capabilities in dermatology. By combining their resources and scientific expertise, both companies hope to maximize the potential of the STAT6 program and bring effective treatments to patients faster.
A New Frontier in Inflammatory Disease Treatment
“Pharma Partners We are excited to expand our inflammation portfolio with this strategic partnership,” said Flavius Martin, M.D., Executive Vice President of Research at Gilead Sciences. “Our goal is to develop next-generation therapies that can support long-term remission in patients with inflammatory diseases by targeting key pathogenic pathways. By blocking the STAT6 signaling pathway, we hope to provide a novel oral option for patients suffering from chronic conditions that impact their quality of life.”
Martin emphasized that this partnership allows Gilead to explore the full potential of the STAT6 pathway, not just in dermatology but also in other areas of inflammation. “We see the STAT6 pathway as having the potential to address a broad spectrum of diseases, and we are eager to explore its role in both dermatology and other therapeutic areas that could benefit from this innovation.”
LEO Pharma Partners, with its deep expertise in dermatology, is equally enthusiastic about the collaboration’s potential to advance treatments for skin diseases. Christophe Bourdon, CEO of LEO Pharma, noted, “STAT6 holds significant promise, not only in dermatology but also beyond. This partnership will enable us to accelerate the development of the STAT6 program, bringing it closer to patients in need. It also highlights LEO Pharma’s scientific expertise and our ongoing commitment to innovating for people with skin diseases.”
The collaboration offers great potential for Pharma Partners patients, as it targets multiple pathways that play a critical role in chronic inflammatory diseases. The oral small molecule inhibitors could provide an easier treatment option for patients, potentially improving adherence to therapy while providing the benefits of targeted treatment that is both effective and less invasive than injectable biologics.
The Pharma Partners Terms of the Agreement
The Pharma Partners terms of the agreement grant Gilead global rights to develop, manufacture, and commercialize the small molecule oral STAT6 program. In addition, LEO Pharma will retain the option to co-commercialize the oral treatments in dermatology markets outside the United States. However, LEO Pharma will retain exclusive global rights to develop and commercialize the topical formulations of the STAT6 inhibitors specifically for dermatology indications.
The financial details of the agreement reflect the scale of the Pharma Partners partnership and its potential for significant future value. LEO Pharma is eligible to receive up to $1.7 billion in total payments, including an upfront payment of $250 million. This upfront payment represents an initial investment by Gilead in the collaboration, and it underscores the value that both companies place on the STAT6 program.
In addition to the upfront payment, LEO Pharma Partners may receive tiered royalties on sales of the oral STAT6 products, ranging from the high single digits to the mid-teens percentage. On the other side of the partnership, Gilead may receive tiered royalties ranging from the high single digits to the mid-teens on sales of topical STAT6 products that LEO Pharma develops.
This agreement also takes into account research and development costs, with Gilead assuming responsibility for the clinical development of the oral program, while LEO Pharma leads the clinical work on the topical formulations. The transaction is expected to have a modest financial impact on Gilead’s earnings per share (EPS) in 2025, with a reduction of approximately $0.15 to $0.17 for both GAAP and non-GAAP EPS.
