Frequently asked questions about Retigabine/ Ezogabine

What is Retigabine used for?

Retigabine is an investigational small molecule being studied for the treatment of seizures and epilepsy. It is specifically being evaluated as adjunctive therapy for partial onset refractory seizures in epilepsy, targeting adult patients aged 18 years and older.

What does Retigabine target?

Retigabine is a small molecule that acts as a potassium channel opener. It works by enhancing the activity of KCNQ potassium channels in the brain, which helps stabilize neuronal activity and reduce the abnormal electrical discharges that cause seizures.

Who makes Retigabine?

Retigabine is being developed by GSK plc, a pharmaceutical company listed on the stock exchange under the ticker symbol GSK. The company has conducted clinical trials to evaluate the drug's efficacy and safety in patients with epilepsy.

What phase is Retigabine in?

Retigabine is in Phase 3 clinical development. It has completed two Phase 3 trials for partial onset refractory seizures in epilepsy, with a total of 845 patients enrolled across multiple countries. The drug is investigational and has not been approved by regulatory authorities.

What clinical trials is Retigabine in?

Retigabine has completed two Phase 3 trials: NCT00232596 with 306 patients and NCT00235755 with 539 patients, both studying adjunctive therapy for partial onset refractory seizures. A Phase 1 trial, NCT01480609, examined the effect of haemodialysis on the drug's pharmacokinetics in epilepsy patients.

Is Retigabine the same as Ezogabine?

Yes, Retigabine is also known as Ezogabine. The Phase 1 trial NCT01480609 specifically studied the effect of haemodialysis on the pharmacokinetics of Ezogabine/Retigabine and its N-acetyl metabolite, confirming that both names refer to the same drug.
