研究概览
简要总结
To determine the convenience and satisfaction of new orally disintegrating tablet formulation (ODT) of lamictal in subjects with a mood disorder. This was a multicenter, open-label study in participants with a mood disorder, who reported difficulty or discomfort in swallowing the currently marketed IR compressed tablet formulation of lamotrigine and who had a person (such as a spouse, partner, companion, aid, nurse, caregiver, etc) willing to complete a Companion/Caregiver Question. Subjects were switched from the currently marketed lamotrigine IR formulation to a matching dose of lamotrigine IR orally disintegrating tablet (ODT) for 3 weeks to determine convenience and satisfaction.

- •Subject must have been taking a stable dose of currently marketed compressed tablet formulation of lamotrigine IR for at least 4 weeks prior to Baseline (Day 1) of the study and must be adherent to the prescribed dosing regimen. The current dose must not exceed 600 mg/day.
- •Subject's current lamotrigine IR dose, frequency and number of tablets per administration must remain consistent between the IR and ODT regimens. However, the subject's current lamotrigine IR dose may be such that the subject would receive no more than one additional ODT per administration in order to equal their IR dose.
- •Subject must currently report a difficulty or discomfort swallowing lamotrigine IR compressed tablets, the nature of which is or will be documented. NOTE: A diagnosis of dysphagia is not required.
- •Subject must have the ability to comprehend the consent form and provide informed consent.
- •Subject must read, write, and comprehend English at a level sufficient to complete study-related assessments.
- •Subject is a male or female at least 18 years of age.

- •non-childbearing potential (i.e., physiologically incapable of becoming pregnant, including any female who is pre-menarchal or post-menopausal [defined as one year without menses]); is surgically sterile [via hysterectomy and/or removal of the ovaries] or,
- •child-bearing potential, has a negative pregnancy test at both Screening and/or Baseline (prior to Investigational Product administration), and agrees to one of the following requirements:
- •has a male sexual partner who is surgically sterilized (vasectomy with documentation of azoospermia) prior to Screening or,
- •sexual partner(s) is/are exclusively female or,
- •double barrier method: condom or occlusive cap (diaphragm or cervical/vault caps) plus spermicidal agent (foam/gel/film/cream/suppository). The subject must be using this method for at least 1 week following the discontinuation of Investigational Product or,
- •any intrauterine device (IUD) with published data showing that the highest expected failure rate is less than 1% per year. Acceptable IUDs, for the purposes of this study, include TCu-380A (Paragard), TCU-380 Slimline (Gyne T Slimline), MULTILOAD-250 (MLCu-250) and 375, Levonorgesterol LNG-20 Intrauterine System (Mirena/Levonova), and Flexigard 330/CuFix PP330 (Gynefix).The subject must have had the device inserted at least 2 weeks prior to Screening, throughout the study, and 2 weeks following the discontinuation of Investigational Product.

结局指标
主要结局
Mean Change From Baseline in the Convenience Subscale Score (CSS) Derived From the Treatment Satisfaction Questionnaire for Medication (TSQM v 1.4) Using Items 9 (Ease of Use), 10 (Ease of Planning to Use), and 11 (Convenience) at Week 3.
时间窗: Baseline, End of Study (Week 3) or Early Withdrawal
The CSS is the sum of items 9 (values: 1=Extremely difficult - 7=Extremely easy), 10 (same set of values as for 9), and 11 (1=Extremely inconvenient - 7=Extremely convenient). The sum has 3 subtracted from it, is divided by 18, and then multiplied by 100; the range is 0-100. Change from baseline=end of study CSS minus baseline score.
