PCAY: Partners in Caring for Anxious Youth
Study Details
Study Description
Brief Summary
Pediatric onset anxiety disorders (generalized anxiety, social anxiety, separation anxiety) are highly prevalent, and if untreated, are impairing into adolescence and adulthood. In the largest comparative efficacy study remission occurred in about 65% of children and adolescents treated with a combination of a selective serotonin reuptake inhibitors (SSRI) and cognitive behavioral therapy (CBT). In contrast, CBT without an SSRI achieved remission in 35% of children at 3 months and 45% at 6 months-a 30% and 20% difference, respectively. Despite the difference in remission rates, CBT alone is the preferred treatment of most patients and families. Lack of awareness of the significant difference in remission rates and concerns about medication side effects may drive patient and family preference even though SSRIs have a positive safety profile.
Critiques of CBT in the above study suggest that CBT was not as effective as it could be due to short treatment duration, restricted family involvement and limited exposure sessions. Would the combination of CBT and an SSRI still be superior to CBT only, if CBT was of longer duration, and included more family involvement and exposure sessions?
In the Partners in Care for Anxious Youth (PCAY) study, children and adolescents with an anxiety disorder ages 7-17 years followed in pediatric primary care clinics affiliated with three institution: Lurie Children's Hospital of Chicago, University of California Los Angeles and University of Cincinnati will be randomized to one of two treatment arms; either CBT only or CBT combined with an SSRI (either fluoxetine, sertraline, or escitalopram). CBT in PCAY will be 6 months in duration and include more family involvement, and more exposure opportunities than past trials. The 6-month acute treatment phase will be followed by 6 months of followup. The primary outcome will be anxiety symptom remission and reduction in impairment over 6 and 12-months.

Detailed Description
Anxiety disorders begin during childhood and adolescents, are extremely common, but are often under-diagnosed and under-treated. If untreated, pediatric anxiety disorders can be chronic and impairing into adulthood. The good news is that evidence-based treatments can be highly effective in reducing symptoms, and for a good number of children and adolescents, treatment can reduce anxiety symptoms to a minimum with marked improvement in function. In the largest comparative efficacy study, remission (minimal or no symptoms of anxiety), occurred in about 65% of children and adolescents treated with a combination of a selective serotonin reuptake inhibitor (SSRI) and cognitive behavioral therapy (CBT). In contrast, CBT without an SSRI achieved remission in 35% of children at 3 months and 45% at 6 months-a 30% and 20% difference, respectively.
Nonetheless, CBT alone is the preferred treatment of most patients and families. Lack of awareness of the significant difference in remission rates and concerns about medication side effects may drive patient and family preference, even though SSRIs have a positive safety profile.
In the study described above, CBT was limited in ways that might account for why it was less effective. CBT was shorter in duration, had fewer sessions, and less exposure opportunities than it was originally designed to have and had less family involvement than more current approaches. Given that patients and families prefer CBT, it is important to know if combination of CBT and an SSRI is truly superior to CBT only or whether fully implemented CBT can close the gap in remission rates with the combination of CBT and an SSRI. The study will also provide information about which children and adolescents achieve remission with CBT or CBT and an SSRI.
The Partners in Caring for Anxious Youth (PCAY) study will screen children and adolescents ages 7-17 years in pediatric primary care clinics affiliated with three institution: Lurie Children's Hospital of Chicago, University of California Los Angeles and University of Cincinnati. If a child screens positive with symptoms of an anxiety disorder, the patient and family will be offered an opportunity to learn about PCAY. If the family is interested in PCAY, a study staff person will provide information and answer any questions. If the patient and family want to enroll they will sign a consent form, complete an evaluation, and if eligible and willing to move forward, be randomized to either CBT or CBT plus an SSRI. The study team will work with the patient and family to connect to a therapist in the community to start CBT and if medication is part of treatment, work with the patient's pediatrician to begin medication. CBT will include up to 20 session of therapy and medication treatment will be a selective serotonin reuptake inhibitor (either fluoxetine, sertraline or escitalopram). The goal of treatment is for the child or adolescent with an anxiety disorder to reach remission and have a marked improvement in functioning. The first part of treatment lasts 6 months and there is then ongoing follow-up for an additional 6 months (12 months total). When the study is finished, the investigators hope to know if CBT and an SSRI is really superior to fully implemented CBT or not. The results of this study will inform patients, families, providers, payors and policy makers on the value of medication when combined with CBT.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Combination therapy (COMB) Participants randomized to this arm will receive cognitive behavioral therapy and one of three study medications (fluoxetine, sertraline, or escitalopram). |
Behavioral: Cognitive Behavioral Therapy (CBT)
Participants randomized to this arm will receive up to 20 sessions of evidence based cognitive behavioral therapy (CBT) of extended duration, with more exposure tasks and greater family involvement than has been studied in the past.
Other Names:
Drug: Combination therapy (COMB)
Participants randomized to this arm will receive cognitive behavioral therapy comparable to that in the cognitive behavioral therapy arm, plus one of three selective serotonin reuptake inhibitors (SSRI) medications (fluoxetine, sertraline, escitalopram)

Outcome Measures
Primary Outcome Measures
- Clinical Global Impression-Severity Scale (CGI-S) [The primary outcome is anxiety disorder remission based on a parent- and child-reported CGI-S rating of 1 (not at all ill) or 2 (borderline ill) at 6 months from first treatment visit]
The CGI-S score provides a global rating of anxiety symptom severity ranging from 1 (not at all ill) to 7 (extremely ill). The CGI-S is commonly used in clinical trials and will allow us to benchmark across prior studies in the field.
- Child Anxiety Impairment Scale-Revised (CAIS-R) [Change in CAIS-R rating of anxiety-related impairment from baseline to 6 months post treatment]
The CAIS-R is a 47-item parent- and child-reported rating of the degree to which anxiety symptoms are impairing the child or adolescent's functioning. Scores range from 0-141 with higher scores indicate poorer functioning.
Secondary Outcome Measures
- Clinical Global Impression-Severity Scale (CGI-S) [The primary outcome is anxiety disorder remission based on a parent- and child-reported CGI-S rating of 1 (not at all ill) or 2 (borderline ill) at 12 months from first treatment visit]
The CGI-S score provides a global rating of anxiety symptom severity ranging from 1 (not at all ill) to 7 (extremely ill). The CGI-S is commonly used in clinical trials and will allow us to benchmark across prior studies in the field.
- Child Anxiety Impairment Scale-Revised (CAIS-R) [Change in CAIS-R rating of anxiety related impairment from baseline to 12 months post treatment]
The CAIS-R is a 47-item parent- and child-reported rating of the degree to which anxiety symptoms are impairing the child or adolescent's functioning. Scores range from 0-141 with higher scores indicate poorer functioning.
