简要总结
Very low dose (VLD) cyclobenzaprine at bedtime has shown promise as a treatment for fibromyalgia, but the chemistry of cyclobenzaprine requires new formulation technology for bedtime use. The present trial is designed to assess the safety and tolerability of 3 different formulations of TNX-102 2.8 mg SL Tablets (a new formulation of cyclobenzaprine designed to result in increased dosage precision and decreased potential for morning grogginess) and to compare the bio-availability of 3 different formulations of TNX-102 2.8 mg SL Tablets (TNX-102 with potassium phosphate, TNX-102-B with sodium phosphate, and TNX-102-C with trisodium citrate) to that of cyclobenzaprine (5 mg tablets).

主要结局
Measured levels of cyclobenzaprine and norcyclobenzaprine in plasma and urine
时间窗: 26 time points per period for blood assessment ; 2 pooled analyses in urine.
Blood samples will be taken per period: within 30 minutes pre-dose and 2, 3.5, 5, 10, 20, 30, and 45 minutes and 1, 2, 2.5, 3, 3.33, 3.67, 4, 4.33, 4.67, 5, 5.5, 6, 8, 12, 16, 24, 36, and 48 hours post-dose. A single urine sample will be collected within 30 minutes pre-dose (one sample), and urine will be pooled from 0-24 and 24-48 hours post-dose.
Safety and tolerability of the 3 formulations of TNX-102 SL Tablets at 2.8 mg
时间窗: Continuously until the end (day 3) of the study period + Telephone follow-up 7-13 days after dosing (total duration: about 1 month)
Every adverse events occurring during the study period will be reported.
