Brief summary
This was an open-label, extension trial designed to evaluate the long-term safety over 12 months of TNX-102 SL tablets taken daily at bedtime for the treatment of fibromyalgia. Patients recruited into this trial were those who had successfully completed the double-blind study, TNX-CY-F202 (F202) (NCT01903265). Patients were not made aware of the therapy they received during the double-blind study.
Detailed description
The study consisted of 7 clinic visits, including Screening/Baseline Visit 1 (Day 0 which was typically the same date as Visit 6 of the double-blind lead-in study), visits after 1, 3, 6, 9, and 12 months of treatment (Visits 2-6), and a Follow-up Visit (Visit 7) scheduled within one month after stopping study drug treatment. Primary: The primary objective of the study was to evaluate the long-term safety of TNX-102 SL tablets taken daily at bedtime over 12 months in patients with fibromyalgia who have completed Study TNX-CY-F202 (NCT01903265) Secondary: The secondary objective was to evaluate the long-term efficacy of TNX-102 SL tablets taken daily at bedtime to control symptoms of fibromyalgia
Interventions
TNX-102 SL 2.8 mg taken daily at bedtime.

Eligibility
Inclusion criteria
1. The patient met all prior inclusion and exclusion requirements for Study F202 (NCT01903265) originally, and has had no intervening medical conditions, increased suicidal ideation, or requirements for concomitant medications that preclude exposure to TNX-102 SL or enrollment in the extension study. 2. The patient completed expected dosing in F202 (NCT01903265) defined as taking study medication up to Week 12, with at least 70% compliance with medication usage (based on responses from daily IVRS calls recorded during the F202 study (NCT01903265)) and no major protocol violations. 3. The patient has provided written informed consent to participate in this extension protocol.

Responder Analysis of Patient's Global Impression of Change (PGIC)
PGIC is a fibromyalgia-specific validated instrument to gauge the patient's assessment of change in condition.The scores are categorized as provided below. A responder was defined by a score of 1 (very much improved), or 2 (much improved). 1. = Very much improved 2. = Much improved 3. = Minimally improved 4. = No change 5. = Minimally worse 6. = Much worse 7. = Very much worse
Time frame: Months 1, 3, 6, 9, 12
Population: Patients who took at least 1 dose of study drug prior to study discontinuation were included in the efficacy analysis. Overall, 36 patients from the Placebo - TNX-102 SL group and 25 patients from the TNX-102 SL - TNX-102 SL group had discontinued the study early. Any missing PGIC responses were included in the scores 3-7 for that visit.
