Pharmacokinetic,Safety and Exploratory Efficacy of RECTIV® in Adolescents With Chronic Anal Fissure
- Registration Number
- NCT01920074
- Lead Sponsor
- Forest Laboratories
- Brief Summary
RECTIV® is an ointment containing 0.4% nitroglycerin (NTG) for the treatment of moderate to severe pain associated with chronic anal fissure approved in June 2011 by the US Food and Drug Administration (FDA) for adults. The purpose of this study is to assess the safety, pharmacokinetics, and exploratory efficacy of RECTIV® in adolescents
- Detailed Description
This is an open-label, multicenter study conducted in up to 10 sites in the United States. A total of 13 pediatric male or female patients age ≥12 to \<17 years will be enrolled. The patients will administer a dose of Rectiv® twice daily to characterize the safety, pharmacokinetics , and exploratory efficacy of Nitroglycerin Ointment 0.4% (RECTIV® )over 5 days

- Primary Outcome Measures
Name Time Method Noncompartmental pharmacokinetic (PK) analyses will be performed on the full pharmacokinetic curves for NTG and its metabolites (1,2 glyceryl dinitrate and 1,3 glyceryl dinitrate) on Day 5 Day 5 The following PK parameters will be calculated as data permit:
* Maximum observed concentration (Cmax)
* Time of the maximum observed plasma concentration (Tmax)
* Area under the concentration time curve from dosing up to the last quantifiable concentration (AUC0-last).
* Area under the concentration time curve from dosing up to 480 minutes (AUC0-480)
* The extrapolated area under the concentration time curve from dosing up to 12 hours (AUC0-12h) also will be calculated if quantifiable concentrations are observed during the entire dose interval.
* Terminal elimination half-life (t1/2) On the basis of the results of the study, additional noncompartmental PK parameters may be calculated and reported.
In addition, a population PK model for NTG will be developed based on the PK data from Day 5. By using this model, the following additional PK parameters may be reported:
* Apparent volume of distribution (V/F)
* Apparent clearance (CL/F)
- Secondary Outcome Measures
Name Time Method • Absolute change from baseline in 24-hour average anal fissure pain scores assessed by the Wong-Baker FACES® and the Numerical Rating Scale for pain after each evening dose over days 1 through 4 Day 5
