Trial Title: Equivalence Among Antiepileptic Drug Generic and Brand Products in People With Epilepsy: Chronic-Dose 4-Period Replicate Design

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: CROSSOVER
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: TRIPLE
- Phase: PHASE4
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~Eligible subjects must satisfy the criteria below at the time of enrollment:~1. 18 years or older.~2. BMI not less than 18.5 and weight not less than 110 pounds.~3. Not donated blood within 56 days of the first pharmacokinetic testing.~4. Agrees not to donate blood at any time during the trial and for 56 days after the final PK in-facility admission.~5. Has had epilepsy for at least one year based on site PIs assessment.~6. Receiving conventional (not extended release) lamotrigine as an antiepileptic drug in twice daily dosing at either 100 mg twice per day, 200 mg twice per day, 300 mg twice per day, or 400 mg twice per day.~7. No changes in AED regimen (lamotrigine or concomitant AED) for at least 28 days prior to first pharmacokinetic testing.~8. Have the ability to understand the informed consent form and be willing to provide informed consent.~9. Willing to remain on same AED regimen through entire study. Subjects will be responsible to supply all of their concomitant medications (except for the study medication, lamotrigine).~10. Willing to stay approximately 14 hours in the research facility on four separate occasions for pharmacokinetic testing.~11. Willing to fast overnight and the morning of each of the four pharmacokinetic testing sessions.~12. Willing to have at least 21 blood samples collected during the pharmacokinetic testing including the in-facility session and outpatient portion for each period. The in-facility blood collections will mainly be performed using an inserted catheter. In the event of difficulty with the catheter or by subject preference, samples may be drawn by venipuncture. The outpatient portion consists of morning trough levels within +/-1 hour of the morning scheduled dose time on the 2 days prior to each research facility PK admission drawn by venipuncture for each of the 4 periods. The total amount of blood during each PK session will be equal to about 12 teaspoons (58.5 milliliters). The total amount of blood drawn throughout the entire study will be about 62 teaspoons (309.5 milliliters) or less. For reference, this amount is approximately two-thirds of the quantity of blood drawn during a standard blood donation by the Red Cross.~13. Willing to completely abstain from alcohol consumption for at least 72-hours prior to each PK in-facility admission (that is from 1 day prior to the first outpatient steady state level) until after the last sample is drawn for each period. Investigators encourage no or minimal alcohol use throughout the study, but alcohol is not restricted at other times.~14. Willing to remain on a consistent regimen of concomitant medications including over-the-counter drugs and herbal drugs, if they are being used and deemed to possibly affect the metabolism of the study medication.~15. Willing to not eat grapefruit or drink grapefruit juice through the duration of the study.~16. If a tobacco user, willing to continue with the same pattern of tobacco use except that no tobacco use is permitted during the PK facility admissions of approximately 14 hours (includes all tobacco products).~17. Willing to complete the subject diary as outlined in the protocol.~18. Willing to adhere to all other protocol requirements as outlined in the informed consent document.~19. Females must be either of non-childbearing potential (defined as having undergone surgical sterilization or postmenopausal (greater than 50 years old and amenorrhea for greater than or equal to 12 months) or must be using at least one acceptable method of contraception as follows:~    1. Double-barrier method (e.g. condom plus spermicide, condom plus diaphragm with spermicide)~   2. Hormonal contraceptive treatment (progesterone only agents - use of any agents containing estrogen are an exclusion for the lamotrigine testing)~   3. Intrauterine Device (IUD)~   4. Monogamous relationship with a vasectomized partner~   5. Abstinent for 8 weeks prior to and throughout the study.~20. Subject must be at least 28 days from last participation in any other study.~Exclusion Criteria:~* 1. Use of an extended release formulation of LTG within 28 days of study entry. 2. Subject is receiving LTG at a total daily dose above 800 mg per day within 28 days of study entry.~  3. Progressive CNS disorder that could influence adverse effects or seizure control.~  4. Known medication non-adherence. Non-adherence is assessed by the investigator based on the procedures defined in the manual of procedures.~  5. Use of valproate (as divalproex sodium or valproic acid), any form of estrogens, rifampin, orlistat, felbamate or sertraline within 28 days of study entry.~  6. Subject has a history of alcohol or substance abuse within 1 year prior to screening of study participation, or is currently using alcohol, drugs of abuse, or any prescribed or over-the-counter medication in a manner, which, in the opinion of the Investigator, indicates abuse.~  7. History of psychogenic seizures within the past 2 years. 8. Any clinically significant psychiatric illness or psychological or behavioral problem which, in the opinion of the investigator, could interfere with the subject being able to participate in the study or comply with the study requirements.~  9. Any clinically significant laboratory abnormality or illness which, in the opinion of the investigator, could interfere with the conduct or interpretation of the study or put the subject at risk.~  10. Pregnant or lactating within 56 days of enrollment. 11. Unstable seizure control that makes AED changes likely during the course of the study.~  12. Use of rescue AEDs (e.g. benzodiazepines) during more than two weeks of the 2 months prior to enrollment.~  13. Subject is in the process of quitting smoking within 28 days of study entry or plans to quit smoking during the period of time the study will be conducted.
