GABAB PAM for cough

We plan to develop our GABAB PAM drug candidate for the treatment of chronic cough.

This target is clinically validated with baclofen, an orthosteric agonist of GABAB, is used off label to treat chronic cough patients. However, baclofen’s use is limited by serious side-effects, short half-life and gradual loss of efficacy during chronic treatment. By more precisely targeting the GABAB receptor with a PAM we aim to have a best-in-class treatment with improved tolerability suitable for the chronic nature of this disease. This indication has a significant unmet medical need and represents a solid commercial opportunity.

We are in late clinical candidate selection phase and have demonstrated proof-of-concept in animal models of cough with several compounds. Subject to funding, we expect IND enabling studies to begin in 2024.
