About this study

Official title: A Study of the Effects of JNJ-26489112 on the Photic Induced Paroxysmal Electroencephalogram Response in Patients With Photosensitive Epilepsy

The purpose of this study is to check the Effects of JNJ-26489112 on the Photic Induced Paroxysmal electroencephalogram (EEG) Response in Patients with Photosensitive Epilepsy.

Read the detailed description

This is a multicenter, non-randomized (participants are assigned deliberately), single-blind (patients do not know which treatment they are receiving), within patient placebo-controlled study. Up to 32 male or female patients will participate in this study. The duration of subject participation is approximately 6 weeks.

Patients will receive the oral doses of study drug in the mornings of Days 1, 2, and 3. All patients will receive a single dose of placebo on Day 1, a single dose of JNJ-26489112 on Day 2, and a second single dose of placebo on Day 3. Blood samples will be taken for evaluation of JNJ-26489112 drug concentrations in plasma and blood. Blood samples will also be collected for laboratory safety assessments and measurement of antiepileptic drug concentrations. Further safety will be assessed by the reporting of adverse events, vital signs, 12-lead ECG, physical and neurological examinations. Patients will be discharged on the evening of Day 3 after the pharmacokinetic samples have been collected, and after assessment by the investigator, unless there are any ongoing adverse events which require in-house monitoring. EEG tracings, recorded during intermittent photic stimulation sessions, will be digitally recorded on a CD-ROM, coded and evaluated independently by one blinded clinical expert to determine the effects on the photosensitivity range. If complete suppression of photosensitivity or reduction of the photosensitivity range by at least 3 points on the photosensitivity scale in at least one eye condition (during closure, closed, open) is not observed in at least 3 of the 4 patients and a maximum tolerated dose has been reached, the study will be stopped. If reduction of the photosensitivity range by at least 3 points on the photosensitivity scale in at least one eye condition (during closure, closed, open) is observed in at least 3 of the 4 patients (with complete suppression in at least 2 patients) in the first cohort, the dose level of JNJ-26489112 may be reduced in subsequent cohorts until the reduction or suppression of photosensitivity is seen in fewer than 2 out of 4 patients in one cohort. Once an effective dose has been reached an additional open-label cohort may be enrolled in which no study drug (JNJ-26489112 or placebo) will be administered to patients. Study drug (i.e., JNJ-26489112 or placebo) will be administered orally as single doses on Days 1 to 3. Placebo will be administered on Days 1 and 3, and a single dose of JNJ-26489112 will be administered on Day 2.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The photosensitivity range in each eye condition (during closure, closed, open) based upon the photoparoxysmal electroencepholgram (EEG) response to intermittent photic stimulation (IPS).

    Measured: Hours 1 to 8 (Day 2) and 25 to 33 postdose (Day 3) with optional assessments at 48, 52, and 56 hours postdose

Secondary outcomes (1)
  1. The safety, tolerability, pharmacokinetics and pharmacokinetic/pharmacodynamic relationship of JNJ-26489112.

    Measured: Day 1 to Day 3 and an optional Day 4

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing JNJ-26489112 in people with Photosensitive Epilepsy, run by Johnson & Johnson Pharmaceutical Research & Development, L.L.C..

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 23 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Apr 2012. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The photosensitivity range in each eye condition (during closure, closed, open) based upon the photoparoxysmal electroencepholgram (EEG) response to intermittent photic stimulation (IPS). (time frame: Hours 1 to 8 (Day 2) and 25 to 33 postdose (Day 3) with optional assessments at 48, 52, and 56 hours postdose). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Apr 2012.
