Study Completion Date:	September 2004

Arms	Assigned Interventions
Placebo group: Placebo Comparator	Other: placebo Patients continued taking the matching placebo that they were taking when they completed Study A6131002 (oral tablets taken once daily).
Alprazolam XR group: Active Comparator	Drug: alprazolam XR Patients continued taking the same dosage of alprazolam that they were taking when they completed Study A6131002 (oral tablets taken once daily (1-6mg)); patients taking less than 6 mg/day who failed to show a satisfactory clinical response since the previous visit, and who were free of dose-limiting adverse events, could have their dosage titrated upward by 1 mg/day; upward daily dosage titration of 1 mg was allowed every 7 days, up to a maximum daily dosage of 6 mg/day; patients who were unable to tolerate the previous dosage level of alprazolam XR could have their daily dosage reduced.

Assigned Interventions

Placebo group: Placebo Comparator

Other: placebo

Patients continued taking the matching placebo that they were taking when they completed Study A6131002 (oral tablets taken once daily).

Alprazolam XR group: Active Comparator

Drug: alprazolam XR

Patients continued taking the same dosage of alprazolam that they were taking when they completed Study A6131002 (oral tablets taken once daily (1-6mg)); patients taking less than 6 mg/day who failed to show a satisfactory clinical response since the previous visit, and who were free of dose-limiting adverse events, could have their dosage titrated upward by 1 mg/day; upward daily dosage titration of 1 mg was allowed every 7 days, up to a maximum daily dosage of 6 mg/day; patients who were unable to tolerate the previous dosage level of alprazolam XR could have their daily dosage reduced.

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.

Eligibility

Ages Eligible for Study:	13 Years to 17 Years
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

A primary Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision diagnosis of panic disorder with or without agoraphobia based on the Mini-International Neuropsychiatric Interview for Children and Adolescents
Subjects with an average of 1) at least one 4-symptom panic attack per week over the last 4 weeks before screening; 2) at least one 4-symptom panic attack per week over the last 4 weeks before baseline; and 3) at least one 4-symptom panic attack in the 7 days prior to baseline
To enter Study A6131007, subjects must have completed Study A6131002, had an acceptable tolerability to study drug, and in the clinical judgment of the investigator, could have benefited from continued study treatment.

Exclusion Criteria:

Subjects must continue to meet all of the exclusion criteria enumerated in the Acute Efficacy Study (Protocol A6131002) with the following exception: Subjects will be allowed to undergo cognitive-behavioral or other panic-specific therapy and any other psychotherapy (e.g., supportive and/or family therapy) during the expected study period in this study.
