What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Pregabalin add-on therapyDrug

    Subjects will be randomized to receive a fixed dose of either placebo, pregabalin Level 1 (maximum 150 mg/day) or pregabalin Level 2 (maximum 600 mg/day) in a 1:1:1 ratio, in addition to the subjects current AED medication regimen. Either capsules or oral liquid form will be administered, depending on subjects preference and ability to swallow capsules, in two equally divided daily doses. The study will have an 8 week baseline period; a 2 week dose escalation period; a 9 week dose maintenance period; and a 1 week dose taper period.

Either capsules or oral liquid form will be administered, depending on subjects preference and ability to swallow capsules, in two equally divided daily doses.

What is being measured

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

  1. Log-Transformed 28-Day Seizure Rate For All Partial Onset Seizures During Baseline Phase

    All partial onset seizures experienced during baseline phase were recorded by the participants or their parents/legal guardian, in a daily seizure diary. 28-day seizure rate for all partial onset seizures = ([number of seizures in the baseline phase] divided by [number of days in baseline phase minus {-} number of missing diary days in baseline phase])*28. For log-transformation, the quantity 1 was added to the 28-day seizure rate for all participants to account for any possible "0" seizure incidence. This resulted in final calculation as: log transformed (28-day seizure rate +1).

    Measured: Baseline phase (up to 8 weeks prior to treatment phase [Day 1])

  2. Log-Transformed 28-Day Seizure Rate For All Partial Onset Seizures During 12-Week Treatment Phase

    All partial onset seizures experienced during treatment phase were recorded by the participants or their parents/legal guardian in a daily seizure diary. 28-day seizure rate for all partial onset seizures = ([number of seizures in the treatment phase] divided by [number of days in treatment phase minus {-} number of missing diary days in treatment phase])*28. For log-transformation, the quantity 1 was added to the 28-day seizure rate for all participants to account for any possible "0" seizure incidence. This resulted in final calculation as: log transformed (28-day seizure rate +1).

    Measured: Day 1 up to Week 12

Secondary outcomes (1)
  1. Percentage of Participants With at Least 50 Percent (%) or Greater Reduction From Baseline in 28-day Seizure Rate During the 12 Week Treatment Phase

    Percentage of participants with 50 percent (%) or greater reduction from baseline in 28-day seizure rate during the 12 week treatment phase were reported. 28-day seizure rate for all partial onset seizures = ([number of seizures in the treatment phase] divided by [number of days in treatment phase minus {-} number of missing diary days in treatment phase])*28.

    Measured: Day 1 up to Week 12

A Phase 3 study testing Pregabalin add-on therapy in people with Epilepsy, Partial Seizures, run by Pfizer's Upjohn has merged with Mylan to form Viatris Inc. at 86 sites in 18 countries.

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 5 inclusion and 7 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 20 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 86 sites in United States, Ukraine, Philippines, Hungary, Turkey (Türkiye) and 13 more countries. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 21 Mar 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Log-Transformed 28-Day Seizure Rate For All Partial Onset Seizures During Baseline Phase (time frame: Baseline phase (up to 8 weeks prior to treatment phase [Day 1])). The study lists 2 primary outcomes in all. 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 NCT01389596, 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 20 Jan 2021.
