Duration of Treatment Effect Using IncobotulinumtoxinA for Upper-limb Spasticity: A Analysis.

The efficacy and safety of incobotulinumtoxinA ≤400 U was demonstrated in subjects with post-stroke upper-limb spasticity in a randomized, double-blind Phase 3 study with an open-label extension (OLEX; EudraCT number 2005-003951-11, NCT00432666). We report a analysis of the duration of the treatment effect. Subjects completing the placebo-controlled main period (single injection cycle with 12-20-week observation) entered the OLEX and received a maximum of five further treatments (maximum duration 69 weeks) with incobotulinumtoxinA ≤400 U at flexible intervals with a minimum duration of 12 weeks, based on clinical need.

Sustained efficacy of incobotulinumtoxina repeated injections for upper-limb post-stroke spasticity: A post hoc analysis.

Objective: This post hoc analysis assessed the impact of repeated incobotulinumtoxinA injections on muscle tone, disability, and caregiver burden in adults with upper-limb post-stroke spasticity.

Design: Data from the double-blind, placebo-controlled main period and three open-label extension cycles of two Phase 3, randomized, multicentre trials were pooled.

Methods: Subjects received incobotulinumtoxinA 400 Units at 12-week intervals (±3 days) (study 3001, NCT01392300) or ≤ 400 Units at ≥12-week intervals based on clinical need (study 0410, NCT00432666).

IncobotulinumtoxinA for upper- and lower-limb spasticity in Japanese patients.

The safety and tolerability of incobotulinumtoxinA 400 U for upper- and lower-limb post-stroke spasticity was assessed in a small cohort of Japanese patients during the open-label lead-in tolerability periods (LITP) of two phase 3 studies (CTI-153029 and CTI-153030; Japan Pharmaceutical Information Centre). Adult patients received a single incobotulinumtoxinA injection session (total dose of 400 U) in the upper (J-PURE) or lower limb (J-PLUS). Adverse events (AEs) were assessed at 1, 4, 8 and 12 weeks post-injection during the 12 week follow-up.

IncobotulinumtoxinA Treatment in Upper-Limb Poststroke Spasticity in the Open-Label Extension Period of PURE: Efficacy in Passive Function, Caregiver Burden, and Quality of Life.

Background: Poststroke spasticity affects motor function and the ability to perform activities of daily living, with the potential to affect quality of life (QoL) and increase caregiver burden.

Objective: To investigate the effect of repeated incobotulinumtoxinA treatment on spasticity-associated functional disability, caregiver burden, and QoL in the 36-week open-label extension of the phase 3 PURE study (NCT01392300).

Design: Open-label extension period of a prospective, double-blind, placebo-controlled, randomized, multicenter study.

IncobotulinumtoxinA Efficacy and Safety in Adults with Upper-Limb Spasticity Following Stroke: Results from the Open-Label Extension Period of a Phase 3 Study.

Introduction: The objective of the study was to investigate the efficacy and safety of repeated incobotulinumtoxinA injections for the treatment of upper-limb post-stroke spasticity in adults.

Methods: Adults 18-80 years of age with post-stroke upper-limb spasticity who completed the 12-week randomized, double-blind, placebo-controlled main period (MP) of a phase 3 trial (NCT01392300) were eligible to enrol in the 36-week open-label extension period (OLEX). The OLEX included three treatment cycles at fixed 12-week injection intervals; subjects were injected with 400 U incobotulinumtoxinA into the affected upper limb.

Randomized, placebo-controlled trial of incobotulinumtoxina for upper-limb post-stroke spasticity.

Introduction: Efficacy and safety of incobotulinumtoxinA in post-stroke upper-limb spasticity were studied.

Methods: Subjects randomized 2:1 to incobotulinumtoxinA (fixed dose 400 U) or placebo, with fixed doses for the primary target clinical pattern (PTCP; flexed elbow, 200 U; flexed wrist, 150 U; clenched fist, 100 U). Doses for non-primary patterns were flexible within predefined ranges.

Efficacy and safety of levetiracetam (up to 2000 mg/day) in Taiwanese patients with refractory partial seizures: a multicenter, randomized, double-blind, placebo-controlled study.

Purpose: To assess the efficacy and safety of adjunctive levetiracetam (LEV) therapy in controlling partial-onset seizures refractory to other antiepileptic drugs (AEDs) in a multicenter study in Taiwanese adults.

Methods: Ninety-four patients aged 16-60 years with refractory partial seizures were randomized to receive LEV (n = 47) or placebo (47) for 14 weeks and composed the intention-to-treat (ITT) population. After the first 2 weeks, LEV patients had their dosage increased from 500 mg twice daily to 1,000 mg twice daily.

Efficacy and safety of levetiracetam 1000-3000 mg/day in patients with refractory partial-onset seizures: a multicenter, open-label single-arm study.

Purpose: To evaluate the efficacy and tolerability of levetiracetam as add-on therapy in patients with refractory partial-onset seizures in a protocol designed to reflect clinical practice.

Methods: All patients in this open-label, single-arm study entered an 8-week baseline period followed by a 4-week titration period and a 12-week maintenance period. Patients initially received levetiracetam 1000 mg/day (administered bid) and could increase to 2000 mg/day after 2 weeks, and to 3000 mg/day after another 2 weeks, to obtain adequate seizure control.

The effects of levetiracetam on objective and subjective sleep parameters in healthy volunteers and patients with partial epilepsy.

Levetiracetam is a novel antiepileptic drug which has recently been released as an adjunctive treatment for partial epilepsy. In the two studies reported here we examined the objective and subjective effects of levetiracetam on sleep in 12 healthy volunteers and 17 patients [16 who could be evaluated for electroencephalogram (EEG) recordings] with a history of partial epilepsy on stable carbamazepine monotherapy. The studies were of a similar double-blind crossover placebo-controlled design with subjects' sleep being recorded in their own homes.
