Oxcarbazepine oral suspension in pediatric patients with partial seizures and/or generalized tonic-clonic seizures: a multi-center, single arm, observational study in China

Abstract

Background

To assess efficacy and safety of oxcarbazepine (OXC) oral suspension in pediatric patients aged 2-16 years with partial seizures (PS) and/ or generalized tonic-clonic seizures (GTCS) in real-world clinical practice in China.

Methods

This 26-week, single arm, multicenter and observational study recruited patients aged 2-16 years with PS or GTCS suitable for OXC oral suspension treatment. Enrolled patients received OXC oral suspension treatment for 26 weeks. Primary endpoints included mean seizure frequency at the end of the treatment and mean seizure frequency reduction at the end of the treatment vs. baseline. Secondary efficacy-related endpoints and safety parameters were also assessed.

Results

Nine hundred and eighty-seven pediatric patients were enrolled and 912 (92.4%) completed the study. The mean seizure frequencies at baseline and the end of week 26 were 13.40±64.92 and 1.62±19.47 times/month, respectively. The mean seizure frequency reduction was 10.03±63.67 times/month and the mean seizure frequency reduction percentage was 90.02%±5127.0% (P<0.0001). After 26 weeks of treatment, 82.36%, 7.24% and 3.86% of the patients became controlled, significantly improved and improved, respectively. Adverse events (AEs) were reported in 74 (7.65%) patients. Rash was the most common AE. The efficacy of OXC was not affected by seizure types, age or gender.

Conclusion

This study confirms the efficacy and good safety profile of OXC oral suspension in Chinese pediatric patients aged 2-16 years with PS and/or GTCS.
