Xyzagen, Inc. Highlights Breakthrough Kv7 Channel Opener Chemistry at AES 2024
Pittsboro, NC, December 15, 2024 – Xyzagen, Inc., a leading pharmacokinetics consultancy and boutique CRO, presented research on its novel Kv7 channel opener compounds at the American Epilepsy Society (AES) Annual Meeting, held December 6–10, 2024, in Los Angeles, CA
The research, titled “New Kv7 Channel Opener Chemistry for the Treatment of Seizures,” showcased promising pharmacological properties of the new chemistry, designed to treat disorders associated with neuronal hyperexcitability, including epilepsy. The findings demonstrated potentially significant advancements over existing clinical development therapies, positioning these compounds as strong candidates for clinical development.
Key Presentation Insights
- Superior Potency: Some molecules demonstrated an EC50 of 50 nM on Kv7.2/7.3 in a patch clamp, surpassing current Kv7 modulators, such as XEN1101 and BHV7000.
- Enhanced Efficacy: Molecules exhibit a >200-fold improvement in Kv7.2 channel opening, with a 25% increase in Emax over ezogabine.
- In Vivo Validation: In rodent models, molecules showed full protection against maximal electroshock-induced seizures (MES) at doses as low as 3 mg/kg in rats and 7 mg/kg in mice, with ED50 values > 0.3 mg/kg in rat, achieving superior efficacy compared to drugs in clinical development.
- PK/PD Relationship: Plasma levels > 200 nM and brain levels > 40 nM led to > 75% of the mice and rats tested protected from the MES induced convulsion.
- Translational Potential: Pharmacokinetic allometric 2-species scaling suggests a 5 mg human dose to be above the 200 nM threshold for 24 h after a single dose, exhibit a half-life of 31 h and allow for self-titration.
Executive Commentary
“The AES Annual Meeting provided an invaluable opportunity to share our novel Kv7 chemistry with the epilepsy research community,” said Chris Crean, Founder and CEO of Xyzagen. “These compounds represent a step forward in addressing the unmet medical needs of patients with epilepsy and other neurological disorders and provide another potential treatment within the expanding clinical Kv7 therapeutic space.”
