  • Subjects who are male or female must agree to use acceptable contraceptive methods as defined in the protocol
  • Subjects who are in otherwise good health

Who cannot join

  • Subjects with a history of non-epileptic transient alterations in consciousness
  • Subjects who have a history of status epilepticus in the past 12 months
  • Subjects whose seizure frequency cannot be quantified
  • Subjects who have significant medical illness including kidney, liver, pulmonary or gastrointestinal disease; or unstable or poorly controlled conditions
  • Subjects who have clinically significant psychiatric illness
  • Subjects with a positive drug screen (excluding any allowed prescribed medications) and history of alcoholism or drug addiction within past 2 years
Show all 12Show fewer
  • Males subjects that have a female partner of childbearing potential who do not agree to use medically approved methods of birth control
  • Male subjects that have a female partner who is pregnant, nursing, or is planning to become pregnant during the study period, or within 90 days of the last dose of study drug
  • Female subjects who are pregnant or lactating, or who are of reproductive potential who do not agree to use medically approved birth-control methods
  • Subjects with a current or prior history of illness precluding them from immunomodulatory therapy (e.g. history of recurrent infections)
  • Subjects with active hepatitis B, hepatitis C, or human immunodeficiency virus (HIV)
  • Subjects who have participated in any other clinical trials involving an investigational product or device and have received the last dose of study drug within 45 days or 5 half-lives of the Screening Visit

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing VX-765 in people with Partial Epilepsy, run by Vertex Pharmaceuticals Incorporated at 12 sites in United States.

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 6 inclusion and 12 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 27 Jan 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Safety and tolerability (vital sign assessments, physical and neurological examinations, laboratory assessments, and adverse events) (time frame: 18 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01048255, which also lists 1 linked publication.

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 27 Jan 2014.
