Sosei Subsidiaries Heptares And Jitsubo To Develop Novel GPCR-Targeting Peptide Candidates For Severe Gastro-Intestinal Disorders



11/10/2016 2:34:42 PM

Tokyo, Japan and London, UK –10 November 2016: Sosei Group Corporation (“Sosei”; TSE Mothers Index: 4565) announces that its subsidiaries, Heptares Therapeutics (“Heptares”) and Jitsubo Co., Ltd. (“Jitsubo”), and have entered into a collaboration to develop novel peptide candidates designed to target a G protein-coupled receptor (GPCR) implicated in severe gastro-intestinal (GI) disorders. This represents the first strategic collaboration between Sosei subsidiaries, highlighting the complementary platforms at its disposal for the discovery and development of a sustainable pipeline of innovative therapeutics targeting diseases with unmet need.

Under the collaboration, Jitsubo will apply its PeptuneTM and Molecular HivingTM peptide engineering technologies and medicinal chemistry capabilities to a GPCR target selected by both Jitsubo and Heptares. Heptares has significant insights into the 3D structure of the receptor via its proprietary StaR® platform. The target GPCR plays an important role in several GI indications and is currently in discovery phase. Heptares will be responsible for development and commercialisation of any peptide candidates that emerge from the collaboration, and will make payments to Jitsubo on achievement of agreed milestones, plus royalties on future sales of any resulting products. No further details are disclosed.

Yusuke Kohno, CEO and co-founder of Jitsubo, said: “Heptares’ StaR® proteins provide an ideal model to apply Jitsubo’s proprietary peptide design and engineering capabilities. We are delighted to begin this first collaboration with Heptares that has the potential to demonstrate the combined power of our platforms for creating novel and highly selective peptide therapeutics targeting important protein receptors.”

Fiona Marshall, Chief Scientific Officer at Heptares and Chief Scientific Officer at Sosei, added: “There are a significant number of GPCRs with strong biological and clinical validation for their role in disease, and whose functions are modulated by peptides. This collaboration, which brings together the complementary platforms of Heptares and Jitsubo, provides an exciting opportunity for Heptares to expand its proprietary pipeline of novel small molecule therapeutics and biologics. We are particularly keen to leverage this collaboration to generate new peptide drug candidates that Heptares can develop itself.”

Peter Bains, Representative Executive Officer, CEO at Sosei, added: “Sosei has built a strong foundation of enabling technologies through M&A over recent years and is focused on leveraging these to deliver a sustainable flow of new drug candidates into our proprietary pipeline. We are very pleased therefore to see this first collaboration between Jitsubo and Heptares, which demonstrates the complementarity of their innovative platforms, and we look forward seeing this programme advance.”

Notes to Editors

About Heptares Therapeutics

Heptares is a clinical-stage company creating transformative medicines targeting G protein-coupled receptors (GPCRs), a superfamily of 375 receptors linked to a wide range of human diseases. Heptares’ proprietary StaR® technology and structure-based drug design (SBDD) capabilities enable us to engineer and develop drugs for highly validated, yet historically undruggable or challenging GPCRs. Using this approach, we are building an exciting pipeline of new medicines (small molecules and biologics) with the potential to transform the treatment of Alzheimer’s disease, schizophrenia, cancer immune-oncology, migraine, addiction, metabolic disease and other indications. We have partnerships for our novel candidates and technologies with leading pharmaceutical and biotechnology companies, including Allergan, AstraZeneca, Kymab, MedImmune, MorphoSys, Pfizer and Teva.

Heptares is a wholly owned subsidiary of Sosei Group Corporation. For more information, please visit www.heptares.com and www.sosei.com.

About Jitsubo Co., Ltd.

Jitsubo has a mission to contribute to the well-being of society through innovative peptide therapeutics and is aiming to become a world class R&D-focused pharmaceutical company that provides solutions to patients using its proprietary peptide-related technologies. Our goals are to address unmet medical needs and administer to the sustainable development of medical care. We pursue these objectives through Molecular Hiving™ (a novel technology to synthesize peptides in high-quality and at lower costs compared to existing methods) and Peptune™ (a peptide structure engineering technology that develops focused peptide libraries during drug discovery). Jitsubo was acquired by the Sosei Group, an international biopharmaceutical drug development company, in December 2014, and enjoys invaluable support in both R&D and global network.
