Unravel Biosciences and CSNK2A1 Foundation Announce Expansion of Collaboration to Identify Drug Candidates for Okur-Chung Neurodevelopmental Syndrome

New study will use Unravel's AI platform to stratify patients into subgroups based on their likelihood to respond to prioritized drugs identified in earlier phase of research.

BOSTON, Aug. 28, 2024 /PRNewswire/ -- Unravel Biosciences, Inc., ("Unravel"), an AI-enabled therapeutics company established to advance drugs for complex diseases, and the CSNK2A1 Foundation ("Foundation") today announced that they are expanding their drug discovery collaboration to now stratify Okur-Chung Neurodevelopmental Syndrome (OCNDS) patients into subgroups based on their predicted response to selected drugs.

Through a previously announced collaboration, Unravel's proprietary BioNAV™ drug discovery platform used RNA data from patient-derived cells and mouse models to identify in silico drug hits. The Unravel study revealed that patient response to predicted drugs may vary significantly based on the location of their specific CSNK2A1 gene mutation causing OCNDS. The Foundation independently confirmed several in silico hits in a Drosophila fruit fly animal model of OCNDS that have the potential for clinical benefit through a screen with Dr. Clement Chow at the University of Utah. As part of its rareSHIFT™ discovery services, Unravel will utilize its proprietary nasal swab collection methodology in the new project to collect RNA transcriptomes from OCNDS patients and matched healthy family members. The data will be processed using BioNAV™ to identify drug candidates most likely to work for patients with specific genetic mutations. This project focuses on the most prevalent OCNDS-causing mutation, K198R, located in the activation segment of CSNK2A1. Currently the Foundation has over 70 individuals registered with this specific variant.

"Given that even monogenetic disorders have substantial variability in how they clinically present and respond to drugs, having a data-driven preview of drug response in real patients is essential to clinically derisk preclinical programs like this," said Richard Novak, Ph.D., Unravel Co-Founder and CEO. "By matching each patient to a drug candidate, we will increase the probability of success in clinical trials and reduce the time and cost of developing meaningful therapies for OCNDS patients."

"This innovative approach allows us to move beyond a one-size-fits-all model, offering the possibility of more personalized and effective therapies for our community," explained Gabrielle Rushing, Ph.D., CSNK2A1 Foundation Science Program Director.  "The insights gained from stratifying patients by their specific genetic mutations will be invaluable in our ongoing mission to accelerate the development of meaningful treatments for OCNDS."

First described in 2016, OCNDS is an ultra-rare genetic syndrome caused by a mutation on chromosome 20 in the CSNK2A1 gene. OCNDS affects every aspect of life, with symptoms ranging from mild to severe and can include the inability to speak or delayed speech, global developmental delay, epilepsy, autism spectrum disorder traits, behavioral challenges, hypotonia, feeding difficulty, and severe sleep disruption. To date, there is no treatment for OCNDS. While the overall prevalence of OCNDS is not fully known, over 250 individuals worldwide are currently registered with the Foundation.
