Brief summary

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 sublingual TNX-102 2.4 mg (a new formulation of cyclobenzaprine designed to result in increased dosage precision and decreased potential for morning grogginess) at pH 3.5 and 7.1 and to compare the bio-availability of sublingual TNX-102 2.4 mg at pH 3.5 and 7.1 and cyclobenzaprine (5 mg tablets, or 2.4 mg iv).

Interventions

DRUGSL TNX-102 2.4 mg at pH 3.5

1 dose of 2.4 mg TNX-102 sublingual solution (2.4 mg/mL) in PBS at pH 3.5, administered as 1 mL held under the tongue for 90 seconds without swallowing

DRUGSL TNX-102 2.4 mg at pH 7.1

1 dose of 2.4 mg TNX-102 sublingual solution (2.4 mg/mL) in PBS at pH 7.1, administered as 1 mL held under the tongue for 90 seconds without swallowing

DRUGCyclobenzaprine Tablet

1 x 5 mg cyclobenzaprine tablet, swallowed with 240 mL of room-temperature water

DRUGCyclobenzaprine IV

1 dose of 2.4 mg cyclobenzaprine USP in PBS (0.6 mg/mL) at pH 7.4, administered intravenously as a 4 mL bolus injection over 30 seconds

Primary

MeasureTime frameDescription
• Measured levels of cyclobenzaprine and norcyclobenzaprine in plasma and urine27 time points per period for blood assessment ; 3 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, 48, and 72 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, 24-48 and 48-72 hours post-dose.
Safety and tolerability of sublingual TNX-102 2.4 mg at pH 3.5 and pH 7.1.Continuously until the end (day 4) 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.
