An Open-Label Interaction Study to Look at the Effects of Brivaracetam on Phenytoin When Taken Together in 15 Adult Patients With Epilepsy.
Phase 1
Completed
- Conditions
- Epilepsy
- Registration Number
- NCT00426673
- Lead Sponsor

- Brief Summary
The primary objective of this Phase I study in 15 adult subjects suffering from epilepsy and chronically treated with phenytoin monotherapy is to evaluate the effect of steady-state ucb 34714 administration on the steady-state plasma levels of phenytoin.

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.

- Primary Outcome Measures
Name Time Method 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 Outcome Measures
Name Time Method information on the tolerability and safety of the simultaneous administration of ucb 34714 and phenytoin in epilepsy patients.
