About this study

Official title: A Randomized, 2-Sequence, 2-Treatment, 4-Period, Open-Label, Single Dose, Fully Replicated Comparative Bioavailability Crossover Study of Two Formulations of Lamotrigine Extended Release Tablets in Healthy Subjects Under Fed Conditions

The objective of this study is to determine bioequivalence between two different formulations of lamotrigine extended release tablets (one reference product and one generic product) in a healthy adult population, following a single oral dose under fed conditions.

Read the detailed description

This is a single center, randomized, open-label, single dose, two treatment, four-period, two-sequence, fully replicated crossover design in the fed state.

The study will include two treatments:

  • Treatment-A: One dose of Lamotrigine extended-release tablet (Test) administered in the morning after a 10-hour overnight fast and 30 minutes after the start of a high-fat, high-calorie breakfast.
  • Treatment-B: One dose of Lamictal XR extended-release tablet (Reference) administered in the morning after a 10 hour overnight fast and 30 minutes after the start of a high-fat, high-calorie breakfast.

A total of 30 healthy subjects will be dosed to ensure that at least 24 subjects will complete the 4-period replicate design. For each treatment period, subjects will be confined from the day prior to dosing until approximately 48 hours post-dose. Subjects will return to the clinical site for the remaining blood samples. There will be a minimum 14-day washout between doses.

Subject participation from the Screening Visit to the Follow-Up Visit will be approximately 71 days.

What is being measured

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

  1. Area Under the Lamotrigine Concentration vs. Time Curve From Sample Time Point 0 Hour to Sample Time Point 144 Hour.

    Pre-dose, and post-dose 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 27, 30, 33, 36, 48, 72, 96, 120, 144 hours

    Lamotrigine and Lamictal have the same active ingredient "Lamotrigine."

    Measured: 144 hours

  2. AUC 0-Inf

    Area Under the Lamotrigine Concentrations vs. time curve from sample time point 0 hour to sample time point 144hours plus extrapolation to infinity of the terminal concentration slope. This describes the total exposure to Lamotrigine. Sampling times include: Pre-dose, and post-dose 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 27, 30, 33, 36, 48, 72, 96, 120, 144 hours.

    Lamotrigine and Lamictal have the same active ingredient.

    Measured: 144 hours

  3. Cmax

    The maximum concentration of the Lamotrigine achieved in specified time frame for each treatment. Sampling times include: post-dose 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 27, 30, 33, 36, 48, 72, 96, 120, 144 hours.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Lamotrigine Extended Release in people with Healthy, run by Food and Drug Administration (FDA) at 1 site 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 23 inclusion and 20 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 1 May 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 1 May 2020). 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?

Area Under the Lamotrigine Concentration vs. Time Curve From Sample Time Point 0 Hour to Sample Time Point 144 Hour. (time frame: 144 hours). The study lists 3 primary outcomes in all. 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 1 May 2020.
