Is this trial a fit for you?

Likely a good fit

Ideal candidates are infants aged 2 to 18 months who have been clinically diagnosed with IESS and have shown a complete response to standard therapy.

Probably not a fit

Patients with significant health issues, ongoing therapies that may interfere with the study, or those who have undergone epilepsy surgery are unlikely to benefit from this study.

What this trial studies

This study aims to evaluate the safety and effectiveness of low-dose prednisolone in preventing relapse in infants diagnosed with Infantile Epileptic Spasms Syndrome (IESS) who have initially responded to standard treatments. Infants aged 2 to 18 months will be randomly assigned to receive either prednisolone or a placebo for four months, with monthly evaluations including clinic visits and EEG monitoring. The study will assess relapse rates, the emergence of other seizure types, and developmental outcomes at age two. The goal is to determine if prednisolone can reduce the risk of adverse outcomes associated with relapse.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the risk of relapse in infants with IESS, potentially improving long-term developmental outcomes.

How similar studies have gone: While there have been studies on treatments for IESS, the specific approach of using low-dose prednisolone to prevent relapse is novel and has not been extensively tested.
