A Study of the Pharmacokinetics (PK) and Safety of IV Carbamazepine Relative to Oral Carbamazepine in Adults With Epilepsy

2014-08-27 03:15:30 | BioPortfolio

Summary

The purpose of this study is to assess the safety, tolerability and steady-state pharmacokinetics of intravenous (IV) Carbamazepine (CBZ) infusions relative to orally administered CBZ in adult patients with epilepsy.

Description

This phase 1, multicenter, sequential, open-label study was designed to assess the safety, tolerability and pharmacokinetics of IV CBZ relative to orally administered CBZ in adult subjects with epilepsy. The study design used an increasing dose/treatment escalation cohort paradigm wherein subjects were enrolled in a cohort based on their total daily dose (TDD) of oral CBZ and their calculated creatinine clearance (CLcr; calculated by the Cockroft-Gault equation) on Day -28. The purpose of the increasing dose/treatment escalation cohort design was to provide a means for the independent data monitoring committee (IDMC) to assess safety prior to enrolling in subsequent cohorts; data were summarized by infusion time, renal function and dose. The initial subjects enrolled had normal renal function (CLcr >= 80 mL/min) and were stable on oral dosing of CBZ from 400 mg/day to 800 mg/day. Subsequent Dosing Cohorts enrolled subjects on higher doses of oral CBZ and allowed subjects with some renal impairment to be enrolled.

Medical and Biotech [MESH] Definitions

A disorder characterized by the onset of myoclonus in adolescence, a marked increase in the incidence of absence seizures (see EPILEPSY, ABSENCE), and generalized major motor seizures (see EPILEPSY, TONIC-CLONIC). The myoclonic episodes tend to occur shortly after awakening. Seizures tend to be aggravated by sleep deprivation and alcohol consumption. Hereditary and sporadic forms have been identified. (From Adams et al., Principles of Neurology, 6th ed, p323)

A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy). (From Adams et al., Principles of Neurology, 6th ed, p313)

An anticonvulsant used to control grand mal and psychomotor or focal seizures. Its mode of action is not fully understood, but some of its actions resemble those of PHENYTOIN; although there is little chemical resemblance between the two compounds, their three-dimensional structure is similar.

An anticonvulsant effective in tonic-clonic epilepsy (EPILEPSY, TONIC-CLONIC). It may cause blood dyscrasias.

An autosomal dominant inherited partial epilepsy syndrome with onset between age 3 and 13 years. Seizures are characterized by PARESTHESIA and tonic or clonic activity of the lower face associated with drooling and dysarthria. In most cases, affected children are neurologically and developmentally normal. (From Epilepsia 1998 39;Suppl 4:S32-S41)
