Clinical Trial Summary

This study proposes to assess the efficacy of Cosyntropin Injectable Suspension, 1 mg/mL compared to vigabatrin. Additionally, this study proposes to determine efficacy of combination therapy of Cosyntropin Injectable Suspension, 1 mg/mL and vigabatrin to monotherapy Cosyntropin Injectable Suspension, 1mg/mL in children with new onset infantile spasms (IS).

Description:

This is a prospective randomized trial comparing 3 treatment arms:

1. Cosyntropin Injectable Suspension, 1 mg/mL

2. Vigabatrin

3. Combination of both these therapies, Cosyntropin Injectable Suspension, 1 mg/mL and vigabatrin for treatment of new onset infantile spasms. Outcome measures include resolution of clinical spasms, improvement of hypsarrhythmia as well as longer term outcomes of development and subsequent seizures.

The data is expected to demonstrate greater efficacy with Cosyntropin Injectable Suspension, 1 mg/mL than vigabatrin for the treatment of IS.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	A comparison of Cosyntropin Injectable Suspension and Vigabatrin on the proportion of subjects who become spasm-free as defined by a) and b).	a) Resolution of hypsarrhythmia via video electroencephalogram (EEG), and b) Resolution of clinical spasms via video EEG.	2 weeks
Secondary	A comparison of combination therapy and Cosyntropin Injectable Suspension alone (monotherapy) on the proportion of subjects who become spasm-free as defined by a) and b)	a) Resolution of clinical spasms for 48 hours at 2 weeks sustained until day 42, and b) Resolution of hypsarrhythmia via video EEG at 2 weeks.	Day 14-42
Secondary	A comparison between combination therapy and Cosyntropin Injectable Suspension alone (monotherapy) on the proportion of subjects who become seizure free at 6 months.	Difference in proportion of subjects who are seizure free between 5 and 6 months after treatment.	6 months
Secondary	Comparison between combination therapy and Cosyntropin Injectable Suspension alone (monotherapy).
