Sponsor:	Pfizer
Information provided by:	Pfizer
ClinicalTrials.gov Identifier:	NCT00634790

Purpose

The purpose of this study is to assess the long-term safety and tolerability of alprazolam extended release (XR) in adolescents with panic disorder, with or without agoraphobia, or in anxiety disorder with panic attacks. Efficacy, population pharmacokinetics of alprazolam XR and the relationship between alprazolam XR plasma concentrations and efficacy outcomes will also be evaluated.

Primary Outcome Measures:

Endpoint change from baseline to Week 24 in Digit Symbol-Coding Test, immediate recall, and delayed recall [ Time Frame: 24 weeks ] [ Designated as safety issue: Yes ]
Baseline-to-peak Physician's Withdrawal Checklist change score during 6-week taper off alprazolam [ Time Frame: 6 week taper ] [ Designated as safety issue: Yes ]
The incidence of treatment-emergent adverse event during treatment with alprazolam XR [ Time Frame: 24 weeks with taper ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

Endpoint change from baseline to Week 24 in the Panic Disorder Severity Scale-Adolescent version total and item scores [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
Endpoint (Week 24) Clinical Global Impression (CGI)-Improvement score [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
Endpoint change from baseline to Week 24 in CGI-Severity score [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
Endpoint (Week 24) Pediatric Quality of Life, Enjoyment, and Satisfaction Questionnaire improvement score [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]

Arms	Assigned Interventions
alprazolam group: Active Comparator	Drug: alprazolam XR Alprazolam XR oral tablet 1 mg daily for 7 days; thereafter the daily dose will be titrated at a maximum rate of 1 mg every 7 days up to a maximum dose of 6 mg; dose adjustments up or down may be made, at a rate not to exceed 1 mg every 7 days; alprazolam XR will be administered for a total of 6 months followed by a gradual taper at a rate of 1 mg every 7 days.

Detailed Description:

Due to recruitment difficulties in this adolescent population, the clinical program for alprazolam XR was cancelled and this study was terminated on 1 September 2004. There were no safety concerns that led to this decision.
