Eligibility Criteria
Inclusion Criteria
- •Well-characterized epileptic syndrome according to the ILAE classification.
- •Patients currently treated with stable phenytoin monotherapy for at least three months and with at least one plasma measurement of pheyntoin within the target range (7 - 23 µg/ml) during the screening period.
Exclusion Criteria
- •History of status epilepticus in the last year.
- •Subjects taking any drug that may significantly influence the metabolism of ucb 34714 (CYP2C or CYP3A potent inducers/inhibitors) except if the dose has been stable at least three months before entry into the study and will be kept stable for the entire trial duration.
- •Subjects with a creatinine clearance of ≤50 mL/min.
Outcomes
Primary Outcomes
to evaluate the effect of steady-state ucb 34714 administration on the steady-state plasma levels of phenytoin.
Blood samples for PK calculations collected at different time points, on Visit 2 and Visit 7, for determination of phenytoin plasma concentrations (Phenytoin levels at pre-dose, 1, 2, 4, 6, 8, 12 (24 if PHT od) hours at V2 and V7)
The drug interaction on phenytoin will be assessed by comparison of AUCτ and Cmax between Visit 2 (phenytoin alone) and Visit 7 (combination of ucb 34714 and phenytoin).
Secondary Outcomes
- information on the tolerability and safety of the simultaneous administration of ucb 34714 and phenytoin in epilepsy patients.
