Dewpoint Therapeutics and Mitsubishi Tanabe Partner on ALS Research

Dewpoint Therapeutics Inc., a prominent biotech company specializing in biomolecular condensates, has entered into a strategic partnership with Mitsubishi Tanabe Pharma Corporation (MTPC) to develop a novel small molecule condensate modulator (c-mod) for treating amyotrophic lateral sclerosis (ALS). This collaboration, effective December 1, 2024, aims to target the underlying pathology of ALS, a condition with significant unmet medical needs.

The agreement stipulates that Dewpoint will receive an initial payment and milestone payments tied to specific research and development goals, with the total deal potentially worth up to $480 million. Once these milestones are achieved, MTPC will have the exclusive global license option to continue the clinical development and commercialization of the c-mod. Additionally, Dewpoint will earn tiered royalties on the net sales of the product.

Dr. Ameet Nathwani, CEO of Dewpoint Therapeutics, expressed enthusiasm about the collaboration, highlighting its potential to address the critical challenges in ALS treatment through an innovative approach. He emphasized that combining Dewpoint's cutting-edge condensate-targeting technology with MTPC's extensive expertise and resources in ALS treatment could significantly accelerate the development of this promising therapy.

Dewpoint's discovery focuses on the TAR DNA-binding protein 43 (TDP-43), which mislocalizes in ALS patients, leading to neuronal dysfunction. The company has identified a small molecule capable of correcting the mislocalization of TDP-43 by restoring its proper localization in the nucleus, thereby preserving normal cellular functions and reducing the pathological effects of the protein. This approach has shown promising results in animal models, improving various ALS biomarkers and promoting neuronal health.

Nathwani noted that the early success of this c-mod in addressing ALS pathology suggests potential applications in other neurodegenerative diseases also characterized by TDP-43 mislocalization.

Dr. Masao Nawano, Vice President and Head of Research Division at MTPC, also expressed excitement about the partnership. He underscored MTPC's commitment to addressing the significant unmet needs in ALS treatment, particularly for patients with sporadic ALS, where genetic causes are unclear. The collaboration with Dewpoint aligns with MTPC's mission to create hope for those facing serious illnesses and generate innovative treatments for critical conditions.

The collaboration leverages Dewpoint's expertise in condensate biology, a field that explores how cells organize and concentrate biomolecules without membranes. Dewpoint's proprietary platform, which uses high-content screening methods, has been instrumental in identifying the small molecule c-mod that forms the basis of this partnership. The company’s approach aims to provide new therapeutic options for diseases historically considered undruggable by targeting the fundamental mechanisms underlying these conditions.

MTPC, with its long history dating back to 1678, continues to focus on central nervous system disorders, among other areas, and aims to enhance patient care through precision medicine and other innovative approaches.

This collaboration represents a significant step in the quest to develop effective treatments for ALS and potentially other neurodegenerative diseases, offering new hope for patients and their families.
