Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 19 to 55 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Male or female subjects aged from 19 to 55 years, inclusive.
  • Body weight >50 kg (males) or >45 kg (females) and BMI within the range 19 - 32 kg/m2 inclusive.
  • Healthy as determined by a responsible physician, based on a medical evaluation including history, physical examination, laboratory tests, vital signs and ECG. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator considers that the finding will not introduce additional risk factors and will not interfere with the study procedures
  • Female subjects of non-child bearing potential will be eligible to participate if they meet the following criteria:
  • Post-menopausal females defined as being amenorrhoeic for greater than 2 years with an appropriate clinical profile, e.g. age appropriate, history of vasomotor symptoms. However if indicated this should be confirmed by oestradiol and FSH levels consistent with menopause (according to local laboratory ranges).
  • Pre-menopausal females with a documented (medical report verification) hysterectomy and/or bilateral oophorectomy, the latter only when the reproductive status of the woman has been confirmed by follow up hormone level assessment.

  • Female subjects of child bearing potential will be eligible to participate if they comply with the contraception requirements.
  • A negative pre-study Hepatitis B surface antigen (HBsAg), Hepatitis C antibody, and HIV antibody result at screening.
  • A negative pre-study urine drug screen.
  • A negative screen for alcohol (urine, blood or breath test).
  • Signed and dated written informed consent prior to admission to the study.

Who cannot join

  • Female subjects of childbearing potential will not be eligible to participate who are unwilling or unable to use an appropriate method of contraception as outlined in the inclusion criteria from at least the commencement of their last normal period prior to the first dose of study medication; and to continue until the first normal period (defined as normal for the woman, both in terms of duration and quantity of menses) after treatment or 5 half lives of the study medication, whichever is the longest .
  • Female subject is pregnant (positive serum human chorionic gonadotrophin (hCG) test at screening) or lactating.
  • Female subjects using hormonal contraceptive precautions including progesterone-coated IUD.
  • Female subjects using oestrogen-containing hormone replacement therapy.
  • Subjects who have received lamotrigine previously (subjects who received placebo in a previous study will be allowed)
  • History or evidence of drug or alcohol abuse within 12 months of study start.
Show all 14Show fewer
  • QTc >450msec for women and QTc >430 msec for men on the screening 12-lead ECG.
  • Current smokers of 10 or more cigarettes per day.
  • History of regular alcohol consumption averaging >7 drinks/week for women or >14 drinks/week for men within 6 months of screening. One drink is equivalent to 12 g alcohol = 5 ounces (150 ml) of wine or 12 ounces (360 ml) of beer or 1.5 ounces (45 ml) of 80 proof distilled spirits.
  • Has received prescribed or non-prescribed medication (including vitamins and herbal remedies) within 14 days prior to the dosing day, which in the opinion of the Principal/Co-Investigator, may interfere with the study procedures or compromise safety.
  • History of gastro-intestinal, hepatic, or renal disease or other condition known to interfere with the absorption, distribution, metabolism or excretion of drugs.
  • History of clinically relevant skin rashes that, in the opinion of the investigator, might interfere with the conduct of the study.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Lamotrigine tablet and Lamotrigine caplet in people with Epilepsy, run by GlaxoSmithKline 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 11 inclusion and 14 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 11 Sep 2017. 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?

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?

Pharmacokinetics ie Serum lamotrigine Cmax and AUC(0-inf) (time frame: Pre-dose and 0.25, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 22, 24, 26, 36, 48, 72, 96, 120 and 144 hours Post-dose). 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 NCT00605371, 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 11 Sep 2017; AzTrials last refreshed its copy on 8 Nov 2026.
