Clinical Trial Summary

This is a prospective study using customized adherence enhancement (CAE) and long-acting injectable (LAI) antipsychotic in 30 individuals with bipolar disorder (BD) at risk for treatment non-adherence. The CAE approach is expected to improve treatment adherence, as well as improve BD symptoms, functioning and treatment attitudes among subjects with bipolar disorder.

Description:

Oral Abilify (aripiprazole) is effective in the treatment of patients with BD when prescribed as an acute anti-manic agent and for the maintenance treatment of bipolar disorder. Abilify Maintena is an intramuscular (IM) depot formulation of oral aripiprazole (Abilify). Abilify Maintena appears to be as effective as standard oral Abilify and may maximize patient adherence. Recent clinical trials suggest that Abilify Maintena is effective for the treatment of patients with BD.

Customized Adherence Enhancement (CAE) is a brief behavioral intervention that improves adherence approximately 30% more than an educational control in adults with BD. The CAE program is a brief, practical intervention consisting of a series of up to four psychosocial treatment modules based upon an adult's unique adherence barriers: 1) Psychoeducation on BD Medications; 2) Communication with Providers; 3) Strategies to Enhance Medication Routines; and 4) Targeting Substance Use Problems with Modified Motivational Enhancement Therapy. Multiple studies conducted by these investigators has shown that CAE is effective in in treating poorly adherent BD adults.

In addition, studies by these investigators have shown that combining LAI + CAE dramatically improves adherence, symptoms and functional outcomes in people with schizophrenia and schizoaffective disorder. In summary, LAI can maximize medication adherence, while CAE addresses individual barriers to sustained adherence and behavioral change. Combining LAI + CAE improves adherence, symptoms and functioning in high-risk people with primary psychotic disorders. The proposed project will test the efficacy of combining Abilify Maintena with CAE to help improve outcomes in poorly adherent patients with BD. Pilot data suggest that adherence with concomitantly prescribed psychotropic drugs improves with LAI + CAE. The findings have particular relevance to BD because many BD patients are on concomitant oral psychotropic drugs in addition to antipsychotic. Thus, it is expected that combining CAE with LAI will lead to a "halo effect" in that these BD patients will engage in their own care more broadly.

Related Conditions & MeSH terms

• Bipolar Disorder
• Disease
• Medication Adherence
• Medication Non Adherence

Intervention

Drug:
• Abilify Maintena
Drug is in an injectable form and will be administered approximately every four weeks through Week 24 of the study. Dosage is per package insert or at the discretion of the psychiatrist.

Behavioral:
• Customized Adherence Enhancement (CAE)
CAE targets key areas relevant to non-adherent populations with schizophrenia or schizoaffective disorder: 1) inadequate or incorrect understanding of mental disorder; 2) lack of medication-taking routines; 3) poor communication with care providers; and 4) substance use which interferes with adherence and healthy behaviors that promote recovery. CAE is delivered based upon initial assessment of reasons for non-adherence and only those components of CAE that are determined to be indicated for that individual are delivered (psychoeducation, modified motivational interviewing, assistance with medication routines, coaching in communication with providers).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Tablets Routine Questionnaire (TRQ, Past Week)	Treatment non-adherence is measured as a percentage of medications not taken within the past week at time of assessment.; The minimum score is 0% and the maximum score is 100%. A higher score implies poorer treatment adherence.	Screen to Week 24
Primary	Change in Tablets Routine Questionnaire (TRQ, Past Month)	Treatment non-adherence is measured as a percentage of medications not taken within the past month at time of assessment.; The minimum score is 0 and the maximum score is 100. A higher score implies poorer treatment adherence.	Screen to Week 24
Primary	LAI Injection Adherence	LAI injection adherence will be determined as a proportion of LAI injections received at the appropriate time (within 7 days of scheduled time).	Baseline to Week 24
Secondary	Change in the Brief Psychiatric Rating Scale (BPRS) Score	The BPRS measure psychiatric symptoms such as depression, anxiety, hallucinations and unusual behavior. The minimum score is 18 and the maximum score is 126. A higher score implies a worse condition.	Baseline to Week 24
Secondary	Change in Young Mania Rating Scale (YMRS) Score	The YMRS measures symptoms of mania. The minimum possible score is 0 and the maximum score is 60. A higher score implies a worse condition.	Screen to Week 24
Secondary	Change in Montgomery Asberg Rating Scale (MADRS) Score	The MADRS measures symptoms of depression. The minimum possible score is 0 and the maximum score is 60. A higher score implies a worse condition.	Screen to Week 24
Secondary	Change in Clinical Global Impressions (CGI) Score	The minimum possible score is 1 and the maximum score is 7. A higher score implies a worse condition.	Screen to Week 24
Secondary	Change in Drug Attitude Inventory (DAI) Score	DAI-10 scoring ranges from -10 to +10 with a total score >0 indicating a positive attitude toward psychiatric medications and a total score of <0 indicating a negative attitude toward psychiatric medications	Screen to Week 24
Secondary	Change in Attitude Towards Medication Questionnaire (AMSQ) Score	A modification of the Lithium Attitudes Questionnaire (Harvey 1991) which evaluates an individual's attitudes towards mood stabilizers. The AMSQ is used to measure attitudes towards medications. The scale contains 19 items grouped into 7 subscales: general opposition to prophylaxis (4 items), denial of therapeutic effectiveness (2 items), fear of side effects (2 items), difficulty with medication routines (4 items), denial of illness severity (3 items), negative attitudes toward drugs in general (3 items), and lack of information about psychiatric medication (1 item). Responses which suggest positive attitudes towards medications are scored "0", while responses which suggest negative attitudes towards medications are scored "1". The items scores are added for a total score which is reported, with the minimum total score of 0 and maximum total score of 19. Higher scores on each subscale represent more negative attitudes toward mood stabilizers.	Screen to Week 24
Secondary	Change in Social and Occupational Functioning Assessment Scale (SOFAS) Score	The SOFAS measures social and occupational functioning independent of the overall severity of the individual's psychological symptoms. The minimum score is 0 and the maximum score is 100. A higher rating implies a higher level of functioning.	Baseline to Week 24
Secondary	Change in Global Assessment of Functioning (GAF) Score	The minimum score is 1 and the maximum score is 100. A higher score implies higher functioning.	Baseline to Week 24
