Ascidian Therapeutics has entered into a significant research collaboration and licensing agreement with Roche, aimed at advancing RNA exon editing therapeutics for neurological diseases. This partnership grants Roche exclusive rights to Ascidian's RNA exon editing technology for undisclosed neurological targets. Ascidian will lead the discovery and certain preclinical activities in collaboration with Roche, while Roche will take responsibility for additional preclinical work, clinical development, manufacturing, and commercialization.
Under the terms, Ascidian will receive an initial payment of $42 million and could potentially earn up to $1.8 billion in milestone payments related to research, clinical achievements, and commercial sales, along with royalties on global sales. Importantly, Ascidian retains the freedom to pursue programs against other neurological targets independently or with different partners.
Michael Ehlers, M.D., Ph.D., President and CEO of Ascidian Therapeutics, expressed pride in the scientific rigor that led to this partnership, highlighting the potential of large-scale RNA exon editing to address diseases currently underserved by gene editing technologies. He emphasized Ascidian's commitment to relieving suffering and enhancing lives through innovative therapeutic approaches.
Roche's Global Head of Pharma Partnering, James Sabry, M.D., Ph.D., acknowledged the opportunity to leverage Ascidian's advanced RNA exon editing platform. This technology holds promise for delivering transformative therapies by editing multiple exons at the RNA level in a single treatment, potentially offering durable therapeutic benefits with reduced risks compared to DNA editing.
Ascidian's RNA exon editing platform is designed to target large and highly mutable genes while preserving natural gene expression patterns. By focusing on RNA rather than DNA, Ascidian aims to combine the lasting effects of gene therapy with enhanced safety profiles.
Currently, Ascidian is actively progressing its clinical pipeline, including ACDN-01, the first RNA exon editing candidate targeting Stargardt disease and related conditions. This therapy recently received U.S. FDA Investigational New Drug (IND) clearance, with ongoing Phase 1/2 clinical trials underway.
Through this collaboration, Ascidian and Roche aspire to pioneer novel treatments that offer patients and their families new hope in managing complex neurological diseases with potentially groundbreaking RNA exon editing medicines.
