Study 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).

Read the detailed 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.

What researchers measure

Primary outcomes

  1. 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.

    Time frame: 2 weeks

Secondary outcomes

  1. 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.

    Time frame: Day 14-42

  2. 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.

    Time frame: 6 months

  3. Comparison between combination therapy and Cosyntropin Injectable Suspension alone (monotherapy).

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 27, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
