A Study to Test the Blood Concentration of 4 Padsevonil Product Variants and the Effect of Food on Padsevonil

UCB Biopharma SRL

Overview

The purpose of the study in Part 1, is to evaluate (under fasted conditions) the plasma pharmacokinetics (PK) of padsevonil (PSL) using 4 PSL product variants against a PSL reference tablet and in Part 2, to evaluate the PK of PSL using a PSL reference tablet under fed and fasted conditions at 200 mg and 400 mg.

Secondary Outcomes

Incidence of Treatment-Emergent Adverse Events (TEAEs)

An Adverse Event is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment.

Time frame: From Baseline up to Day 35

Incidence of Serious Adverse Events (SAEs)

A Serious Adverse Event (SAE) is any untoward medical occurrence that at any dose: * Results in death * Is life-threatening * Requires in patient hospitalization or prolongation of existing hospitalization * Is a congenital anomaly or birth defect * Is an infection that requires treatment parenteral antibiotics * Other important medical events which based on medical or scientific judgement may jeopardize the patients, or may require medical or surgical intervention to prevent any of the above

Time frame: From Baseline up to Day 35
