Development and Use of a High-Throughput Screen to Identify Novel Modulators of the Corticotropin Releasing Factor Binding Protein

­Development of a HT Screen to Identify Novel Modulators of the CRFBP

 
Overview
A connection between the corticotropin signaling pathway and alcohol use disorder (AUD) has been shown previously. We developed a high throughput screen to identify small molecule modulators of this pathway as potential therapeutics for AUD.
 
Market Opportunity
Currently available treatments for alcohol use disorder (AUD) include three pharmacotherapies approved by the Food and Drug Administration: disulfiram, naltrexone, and acamprosate. The clinical efficacy of these pharmacotherapies is marginal, and they all suffer from limiting contraindications. Thus, there is a critical need for more effective pharmacotherapies for AUD. 
 
Innovation and Meaningful Advantages
Growing attention has been paid to the stress system—specifically, the signaling pathway of corticotropin releasing factor (CRF)—as a pharmacological target for AUD, and the expression pattern of CRF binding protein (CRFBP) suggests a critical role in the modulation of the stress responses. Using a novel high throughput screen we developed, we were able to identify two negative allosteric modulators (NAMs) of CRFBP.  

Commercial Development: Current State and Next Steps
We transferred this novel biological assay to our collaborator’s robotic facility and have screened >350,000 compounds. We have selected 2 allosteric modulators and tested them in an ex vivo preclinical alcohol model.

Collaboration Opportunity
Our goal is to collaborate with biopharma partners/funders who can bring into play the developmental, translational, and financial resources needed to advance this technology into the commercial marketplace.
