Frequently asked questions about BHV-700

What is BHV-700 used for in epilepsy?

BHV-700 is an investigational small molecule being developed for the treatment of epilepsy and seizures. It is currently in Phase 1 clinical development, with an active study evaluating its use in patients with epilepsy. The drug is not yet approved and remains under investigation.

What does BHV-700 target?

BHV-700 targets the Kv7.2 and Kv7.3 potassium channels, which are involved in regulating neuronal excitability. By modulating these channels, the drug aims to reduce abnormal electrical activity in the brain that can lead to seizures. This mechanism is being studied for its potential in treating epilepsy.

Who makes BHV-700?

BHV-700 is being developed by Biohaven Ltd., a biopharmaceutical company. The company is conducting clinical trials to evaluate the drug's safety and efficacy in patients with epilepsy. Biohaven is publicly traded under the ticker symbol BHVN.

What phase is BHV-700 in?

BHV-700 is in Phase 1 clinical development. It is an investigational drug and has not been approved by regulatory authorities. The ongoing Phase 1 study is designed to assess the drug's safety, tolerability, and preliminary effects in patients with epilepsy and seizures.

What clinical trials is BHV-700 in?

BHV-700 is being studied in a Phase 1 clinical trial with the identifier NCT07125261. This trial, titled 'BHV-7000 Responsive Neurostimulation System (RNS) Study,' is active but not recruiting and is enrolling approximately 5 participants in the United States. The study is open to adults aged 18 years and older with epilepsy or seizures.

Is BHV-700 the same as BHV-7000?

Yes, BHV-700 is also known as BHV-7000. The clinical trial NCT07125261 uses the name BHV-7000 in its title, referring to the same investigational drug. This alternative name may appear in trial registries and scientific literature related to the drug's development for epilepsy.
