NEW YORK, BOSTON and LONDON, Oct. 18, 2021 (GLOBE NEWSWIRE) -- Schrödinger (Nasdaq: SDGR) and Centessa Pharmaceuticals plc (“Centessa”) (Nasdaq: CNTA), together with subsidiary Orexia Therapeutics (“Orexia”), today announced an exclusive collaboration focused on the discovery of novel therapeutics targeting the orexin-2 receptor (OX2R), which is known to play a role in a broad spectrum of sleep disorders including narcolepsy. The collaboration provides Orexia with substantial access to Schrödinger’s entire computational platform as well as Schrödinger’s extensive expertise in ultra-large-scale deployment of its technology.

Orexia will leverage Schrödinger’s computational platform, including LiveDesign and Free Energy Perturbation (FEP+), which facilitates high-performance calculations for drug discovery to enable accurate prediction of potency at the target of interest. The collaboration will be enabled by Orexia’s structural biology capabilities, including the stabilized OX2R StaR® protein exclusively licensed from Sosei Heptares, and high-resolution crystal structures in agonist conformation. The collaboration represents the first time Schrödinger’s technology will be applied in an orexin agonist setting at scale.

“While prevailing treatment approaches only address the symptoms associated with narcolepsy type 1 (NT1), we believe orexin agonists offer a disruptive approach, with the capacity to address the underlying pathology of the disorder. Orexia’s utilization of OX2R stabilized receptors (StaR® technology) provides the foundation for R&D which could significantly benefit patients with NT1. We look forward to partnering with Schrödinger to complement the discovery and development work we are conducting at Orexia,” said Saurabh Saha, MD, PhD, Chief Executive Officer of Centessa.

“Orexia’s asset-centric approach enables us to pick the best technology partners for discovery and development. While we expect to enter IND-enabling studies with our lead molecule next year, we are also delighted to work with Schrödinger to enable the acceleration of our discovery efforts for molecules with potentially differentiated clinical profiles. Indeed, the therapeutic possibilities of orexin agonists extend well beyond NT1 into other rare primary hypersomnia disorders, such as narcolepsy type 2 and idiopathic hypersomnia, and into a broad range of additional indications characterized by excessive daytime sleepiness. We are committed to exploring the full potential of orexin agonists to help patients across a wide range of indications,” said Mario Alberto Accardi, PhD, Chief Executive Officer of Orexia.

"Our research collaboration with Orexia is illustrative of a new approach to help support discovery efforts at biotech companies, where we apply our technology at scale on behalf of our collaborator," stated Ramy Farid, PhD, President and Chief Executive Officer of Schrödinger. “The Orexia team brings deep experience in orexin biology and structure-based drug design, and we’re excited to provide Orexia with large-scale access to our leading computational approaches and expertise to accelerate the discovery of novel therapeutics targeting orexin biology.”

Under the terms of the agreement, Orexia will be responsible for preclinical research activities, clinical development and commercialization of future product candidates discovered under the collaboration. Schrödinger will receive an upfront software access payment and may become eligible to receive certain preclinical, development, regulatory and commercial milestone payments, as well as low single digit royalties on global net sales.  

About Schrödinger
Schrödinger is transforming the way therapeutics and materials are discovered. Schrödinger has pioneered a physics-based software platform that enables discovery of high-quality, novel molecules for drug development and materials applications more rapidly and at lower cost compared to traditional methods. The software platform is used by biopharmaceutical and industrial companies, academic institutions, and government laboratories around the world. Schrödinger’s multidisciplinary drug discovery team also leverages the software platform to advance collaborative programs and its own pipeline of novel therapeutics to address unmet medical needs.

Founded in 1990, Schrödinger has over 500 employees and is engaged with customers and collaborators in more than 70 countries. To learn more, visit and follow us on LinkedIn and Twitter.

About Centessa Pharmaceuticals
Centessa Pharmaceuticals plc aims to bring impactful new medicines to patients by combining the strengths of an asset-centric model with the benefits of scale and diversification typical of larger R&D organizations. The asset-centric model refers to a highly specialized, singular-focused company that is led by a team of well-recognized subject matter experts. Centessa’s asset-centric companies’ programs range from discovery-stage to late-stage development and include diverse therapeutic areas such as oncology, hematology, immunology/inflammation, neuroscience, hepatology, pulmonology and nephrology.

About Orexia Therapeutics
Orexia was founded by venture capital firm Medicxi in collaboration with Heptares Therapeutics Limited, a wholly owned subsidiary of Sosei Group Corporation (Sosei Heptares), and leverages Sosei Heptares’ GPCR StaR® technology to develop oral and intranasal orexin receptor agonists using structure-based drug design approaches. These agonists target the treatment of narcolepsy type 1, with the aim to directly address the underlying pathology of orexin loss, as well as other neurological disorders characterized by excessive daytime sleepiness.
