Safety, Tolerability, and Exploratory Efficacy of Adjunctive EQU-001 for Seizures in Adults With Epilepsy

This is a double-blind, placebo controlled, randomized study of dose-ranging safety, tolerability, exploratory efficacy of adjunctive EQU-001 for seizures using the continuous reassessment method in patients diagnosed with epilepsy.

EQU-201 is a Phase 2 randomized, double-blind, placebo-controlled study to evaluate dose-ranging safety, tolerability, and exploratory efficacy of adjunctive EQU-001 using the continuous reassessment method (CRM). 10 participants diagnosed with epilepsy according to the International League Against Epilepsy (ILAE) Classification of the Epilepsies 2017 criteria whose seizures are uncontrolled on one to four concomitant antiepileptic drugs (AEDs) for ≥4 weeks will be enrolled in 4 dose cohorts (10 mg, 20 mg, 40 mg, 60 mg) The participants will be randomized 4:1, drug to placebo. The dosing is for 12 weeks, after which, safety data will be reviewed post 14 days to determine whether the next cohort can be opened. Once the 12-week study dosing period is complete, all subjects may enroll in an open-label extension, during which period investigators may make dose adjustments down to 20 mg and up 80 mg. This study of EQU-001 will provide safety of a range of doses, tolerability, and PK data in patients with epilepsy and aims to identify drug-specific DLTs and MTD. The PK component will characterize the PK of EQU-001 to inform dosing and may help to correlate exposures with any DLTs or other treatment-related AEs. The open label extension component will provide data on subject safety, tolerability and efficacy.
