A Modern Design for a Phase 2/3 Randomized, Double-blind, Placebo-Controlled Study to Evaluate Efficacy and Safety of BHV-7000 in Idiopathic Generalized Epilepsy with Generalized Tonic-Clonic Seizures (AAN 2025) - P2/3 | "SHINE is an innovative registrational study in IGE with the differentiated Kv7 activator BHV-7000. This patient-centric study utilizes a TTE endpoint that decreases time on placebo, potentially reducing the risk of exposure to additional seizures, injury, and SUDEP."

Phase 1 Multiple Ascending Dose Studies Demonstrate Favorable Safety and Tolerability of BHV-7000, a Novel Kv7 Potassium Channel Activator (AAN 2025) - "BHV-7000 was safe and well tolerated in multiple-dose Phase 1 studies across all doses evaluated for up to 15 days. Adverse events typically associated with other ASMs, such as somnolence and cognitive/mood disturbances, were not reported at equivalent doses to those currently being dosed in Phase 3 trials in focal epilepsy, generalized epilepsy, major depressive disorder, and bipolar disorder."

Targeting Kv7 Potassium Channels for Epilepsy. (PubMed, CNS Drugs) - "Ezogabine (retigabine), the first Kv7.2/3 activator introduced in 2011 for the treatment of focal seizures, was withdrawn from the market in 2017 due to declining use after discovery of its association with pigmentation changes in the retina, skin, and mucosae...Another Kv7.2/3 activator, BHV-7000, has completed phase I studies in healthy subjects, with excellent tolerability at plasma drug concentrations that exceed the median effective concentrations in a preclinical model of anticonvulsant activity, but no efficacy data in patients with epilepsy are available to date. Among other Kv7.2/3 activators in clinical development as potential antiseizure medications, pynegabine and CB-003 have completed phase I safety and pharmacokinetic studies, but results have not been yet reported. Overall, interest in targeting Kv7 channels for the treatment of epilepsy and for other indications remains strong. Future breakthroughs in this area could come from exploitation of mechanistic..."

Phase 1 Multiple Ascending Dose Studies Demonstrate Safety and Tolerability of BHV-7000, a Novel kv7 Potassium Channel Activator (AES 2024) - "BHV-7000 was well tolerated in multiple-dose Phase 1 studies across all doses evaluated, without AEs typically associated with other anti-seizure medications. These findings support the continued clinical development of BHV-7000 as a novel ASM with the potential to reduce seizures while minimizing AEs. Patients are currently being enrolled in multiple Phase 2/3 studies evaluating the efficacy and safety of BHV-7000 in focal and generalized epilepsy as well as neuropsychiatric disorders."

Pharmacological Characterization of BHV-7000, a Novel and Selective Activator of kv7.2/kv7.3 Channels, Using All-optical Electrophysiology (AES 2024) - "Overall, BHV-7000 demonstrated potent in vitro effects to reduce neuronal activity impacting a diverse set of Optopatch functional features across the stimulus protocol, including spike timing and spike shape features in different stimulus periods, which indicates lower excitability near action potential threshold. Compound effects were more pronounced (additional altered features detected) under the more Chronic Regimen A compared to Regimen B, suggestive of neuronal remodeling with longer treatment. Lastly, the fraction of neurons staying completely silenced during a long gentle blue stimulus period can effectively distinguish ASMs treated wells from DMSO wells in a parallel neuronal excitability assay using human iPS cell-derived cortical excitatory ("NGN2") neurons, suggesting relevance of this measure for predicting an efficacious ASM."

New kv7 Channel Opener Chemistry for Treatment of Seizures (AES 2024) - "Kv7 channel opening is a validated target for epilepsy with the approval of ezogabine (EZG) in 2011 as a first-in-class molecule; it was removed from the market in 2017. Kv7 openers BHV7000 and azetukalner (XEN1101) are currently in clinical development... In vivo, PO efficacy in rodent MES is >10-fold over aztukalner (ED50 > 4 mg/kg) and BHV7000 (full protection at 3 mg/kg). It is anticipated that the lead molecule, based on an in vivo minimum effective brain concentration of >20 nM for MES in mice and rats, a half maximal voltage shift of ~7 mV at 0.7 in rodents, may be effective at a plasma conc. of 30 nM, as a threshold conc., for clinical seizure protection in humans."

BHV-7000 Is a Potent M-current Activator with Efficacy on Multiple Epilepsy-associated KCNQ2 Variants (AES 2024) - "BHV-7000, a selective M-current activator restored current density in all tested pathogenic KCNQ2 variants. For most of the tested variants, current density was restored to near WT levels with 1 μM BHV-7000. The calculated BHV-7000 EC50 values were similar to WT for the majority of the variants tested."

Effects of BHV-7000 on human iPSC-derived sensory neurons from IEM patients (IASP 2024) - "This study demonstrated that BHV-7000 hyperpolarized the resting membrane potential, increased the rheobase, and decreased the action potential firing rate at 3X rheobase from iPSC-SNs using standard patch-clamp recordings. In IEM-iPSC-SNs from 2 IEM patients, multi-electrode-array recordings demonstrated potent inhibition of spontaneous firing with BHV-7000. In addition, current-clamp recording from one IEM-iPSC cell line demonstrated that BHV-7000 hyperpolarized iPSC-SN resting membrane potential."
