正式标题 ^ICMJE

A Multicenter, Open-label, Parallel-group Study in Study Participants With Epilepsy, to Evaluate the Effect of Oxcarbazepine on the Pharmacokinetics, Safety, and Tolerability of Padsevonil

简要概况

The purpose of the study is to evaluate the effect of stable coadministered oxcarbazepine (OXC), on the pharmacokinetics (PK), safety, tolerability of padsevonil (PSL) and the plasma PK of PSL metabolites, UCB1431322-000 and UCB1447499-000, in study participants with epilepsy compared with study participants co-medicated with stable doses of levetiracetam (LEV), lamotrigine (LTG) or brivaracetam (BRV) therapy.

Experimental: Cohort 1
Cohort 1 (Inducers): Study participants on stable therapy with oxcarbazepine (OXC) either as monotherapy or adjunctive to levetiracetam (LEV), lamotrigine (LTG), or brivaracetam (BRV). OXC may be used as monotherapy or in combination with 1 or more of LEV, LTG, or BRV. Padsevonil (PSL) will be dosed to steady state and the effect of background therapy on PSL pharmacokinetics will be assessed at steady state.
Experimental: Cohort 2
Cohort 2 (Neutral): Study participants on stable therapy with lamotrigine (LTG), levetiracetam (LEV), or brivaracetam (BRV). LTG or LEV may be used as monotherapy or in combination with each other. BRV may only be used in combination with LTG. LTG or LEV may be used as monotherapy or in combination with each other. BRV may only be used in combination with LTG. Padsevonil (PSL) will be dosed to steady state (4.5 days) and the effect of background therapy on PSL pharmacokinetics will be assessed at steady state.
