Summary

Purpose of this study is to examine the effectiveness of an experimental psychotherapy (talk therapy) for the treatment of bipolar II depression. The name of this psychotherapy is Interpersonal and Social Rhythm Therapy for Bipolar II Depression (IPSRT-BPII). Subjects will be randomly assigned to receive either IPSRT-BPII or the medication Seroquel (quetiapine) to manage their symptoms of bipolar II depression. Subjects will receive the assigned therapy for up to 20 weeks.

Detailed description

The proposed pilot study is an experimental design intended to investigate the preliminary efficacy of Interpersonal Social Rhythm Therapy for Bipolar II Depression (IPSRT-BPII). A total of 56 eligible subjects with a diagnosis of bipolar II disorder will be randomly assigned to one of two treatment groups : Seroquel (n=28) or IPSRT-BPII (n=28). Following baseline assessment, all participants will undergo up to 20 weeks of their assigned treatment. Patients assigned to IPSRT-BPII who fail to respond (at least 50% reduction in HRSD-25 scores and YMRS ≤ 10) by week 12 will have Seroquel added to IPSRT-BPII. Subjects who achieve remission (defined as 3 consecutive weeks where both HRSD-25 and YMRS scores average ≤ 7) and have participated in the trial for a minimum of 12 weeks will be moved into a continuation phase where they will receive maintenance treatment (bi-monthly therapy sessions and/or pharmacotherapy) until week 20. Patients who do not achieve remission by Week 20 will be discontinued from treatment and referred for follow-up care. All subjects (remitters and non-remitters) will be assessed at 20 weeks.

Conditions

• Bipolar II Disorder

Interventions

Type	Name	Description
BEHAVIORAL	Interpersonal and Social Rhythm Therapy (IPSRT-BPII)	IPSRT is comprised of three components: psychoeducation, social rhythm therapy, and standard IPT as developed for unipolar depression. Psychoeducation focuses on a) the illness and its consequences, b) treatment options and associated side effects, and c) prodromal symptoms/detection of early warning symptoms.
DRUG	Seroquel	Subjects will be started at 100 mg/day titrated to a maximum of 800 mg /day Day 1-BID doses totaling 100 mg/day, increased to 400 mg/day on Day 4 in increments of up to 100 mg/day in BID divided doses, by Day 6 begin titration up to a maximum dose of 800 mg/day in increments no greater than 200 mg/day. This titration schedule may be adjusted based on the subject's response and ability to tolerate Seroquel. Subjects who are unable to tolerate the study medications, or for whom the study medications are an inappropriate clinical choice, will be treated openly by a clinic physician according to the standard of care guidelines designated by the American Psychiatric Association (2002) for the treatment of bipolar disorder.
