Comparative Bioavailability of Sublingual TNX-102, Oral and Intravenous Cyclobenzaprine in Healthy Adults

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).

Treatment and study plan

SL TNX-102 2.4 mg at pH 3.5

Drug

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

SL TNX-102 2.4 mg at pH 7.1

Drug

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

Cyclobenzaprine Tablet

Drug

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

Cyclobenzaprine IV

Drug

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 outcomes

  1. • Measured levels of cyclobenzaprine and norcyclobenzaprine in plasma and urine

    Time frame: 27 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.

  2. Safety and tolerability of sublingual TNX-102 2.4 mg at pH 3.5 and pH 7.1.

    Time frame: 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.
