Clinical Trial: A Study to Investigate the Effect of ICA-105665 in Photosensitive Epilepsy Patients

Study Status: Terminated
Recruit Status: Terminated
Study Type: Interventional

Official Title: A Phase 2, Multi-Center, Single-Blind, Placebo-Controlled Pharmacodynamic Evaluation of ICA-105665 in Epilepsy Patients With a Photo-Induced Paroxysmal EEG Response

Brief Summary: Subjects with epilepsy with a documented photoparoxysmal response to intermittent photic stimulation (IPS) will participate. Four subjects will be enrolled at each dose level and will receive a single dose of placebo and a single dose of ICA-105665 during the study, each followed by intermittent photic stimulation. The effects of ICA-105665 on the photoparoxysmal electroencephalography (EEG) response of each group will be reviewed before the dose is selected for each subsequent group of subjects.

Detailed Summary:
Sponsor: Pfizer

Current Primary Outcome: Change in photosensitivity response [ Time Frame: begin 1 hr post dose for 8 hours ]

Original Primary Outcome: Same as current

Current Secondary Outcome:

  • To correlate plasma concentrations of ICA-105665 with effect on the frequency range of IPS-induced PPR (Photoparoxysmal response) in subjects with photosensitive epilepsy. [ Time Frame: 3 days ]
  • To assess the safety of a single dose of ICA-105665 in subjects with photosensitive epilepsy. [ Time Frame: 30 days ]


Original Secondary Outcome:
