CMTA and Addex Therapeutics Enter Collaboration to Advance GABA B PAM as Potential Treatment for CMT1A

Addex TherapeuticsAddex Therapeutics is a clinical-stage pharmaceutical company pioneering allosteric modulation-based drug discovery and development. CMTA and Addex have formed a collaboration to investigate a potential therapy for CMT type 1A (CMT1A), the most common subtype of the disease, which affects approximately 1.5 million people.

The primary goal of the collaboration is to evaluate the benefit of Addex’s proprietary positive allosteric modulator’s (PAM’s) targeting the gamma-Aminobutyric acid subtype B (GABAB) receptor in rodent models of CMT1A. The GABAB receptor has previously been shown to be instrumental in controlling the overexpression of Peripheral Myelin Protein-22 (PMP22) in a rat model of CMT1A. Elevated PMP22 is closely associated with the disabling peripheral neuropathy that accompanies CMT1A.

The research alliance with Addex will include joint study planning aimed at the chronic dosing of select GABAB PAM’s in rodent models of CMT1A, followed by detailed assessments aimed at measuring the improvement of key outcomes. These outcome measures include biomarkers, motor function, electrophysiology and peripheral nerve histology. This is made possible through the CMTA’s preclinical testing alliance: www.cmtausa.org/our-research/for-researchers/cmta-preclinical-testing-network/
