Clinical Trial Summary

The aim is to evaluate aerobic group exercise versus leisure group activities in adolescents with mild to moderate depression.

Primary outcome is Children's Depression Rating Scale - Revised (CDRS-R). Secondary outcomes are Clinical Global Impressions - Severity and Improvement scales (CGI), self-reported Quick Inventory of Depression Symptomatology (QIDS- A17-SR), the self-reported Outcome Rating Scale (ORS), clinician rated Children Global Assessment Scale (C-GAS), aerobic capacity (VO2max), muscular strength, body, Body Mass Index (BMI), presence or activity of selected biological markers of neuroprotection and neuroinflammation in blood samples and a cost evaluation rated by parents with Trimbos/iMTA questionnaire for Costs associated with Psychiatric Illness - Child version (Tic-P). Further objectives are qualitative interviews to explore adolescents' experiences of the intervention as well as how their health and lifestyle are influenced and a validation of QIDS- A17-C and QIDS- A17-SR versus CDRS-R will be performed.

Description:

Detailed Description: Depression is common in adolescence and prevalence is increasing. It is a major cause of disability in adolescents worldwide and contributes to lower educational achievements, increased risks of substance abuse, suicide and a risk factor for cardiovascular disease. The effect of evidence based treatments with antidepressants or psychotherapy such as cognitive behavioural therapy (CBT) or interpersonal therapy (IPT) are modest. Selective serotonin uptake inhibitors (SSRIs) have shown effect on depression in children and adolescents, but the effect is often insufficient.

Aerobic exercise seems to have effect on depression in adolescents but studies have several shortcomings. Recruitment was mostly in non-clinical or primary care facilities, results are heterogeneous and adequate control groups are lacking. More data on qualitative, cost-effectiveness and biomarker aspects are clearly warranted.

Objectives

1. Primary objective To evaluate aerobic group exercise versus leisure group activities on clinician rated depression symptoms among adolescents in child and adolescent outpatient care with mild to moderate depressive disorder by measuring changes in Children's Depression Rating Scale- Revised (CDRS-R).

2. Secondary objectives Secondary objectives are clinician rated Clinicial Global Impression - Severity (CGI-S) and Improvement scales (CGI-I) and function with Children Global Assessment Scale (C-GAS), self-rated symptoms (QIDS-A17-SR) and function with the Outcome Rating Scale (ORS), aerobic capacity measured by a submaximal aerobic capacity test, muscular strength measured by the isometric mid-thigh pull strength test, a hand grip strength test and muscular endurance by the one-leg sit-to-stand test, and body composition with a bioelectrical impedance analysis and presence or activity of selected biological markers of neuroprotection and neuroinflammation in blood samples.

Moreover, the investigators will assess cost-effectiveness in this trial. Another secondary objective is to explore adolescents' experiences of the intervention as well as how their health and lifestyle are influenced by the intervention through qualitative interviews. Finally, we will validate the QIDS- A17-C and QIDS-A17-SR against CDRS-R.

The statistical power of this trial is not designed to arrive at significant findings, but to validate the measures and data collection approach and to gather preliminary data to inform the power analysis when planning the full-scale RCT.

Project description

1. Design The study will be a one-sited randomized pilot study that will include 24 adolescents with ongoing mild to moderate depression after three or more visits and brief psychosocial interventions. Participants will be randomized to receive 12 weeks of either aerobic group exercise or leisure group activities at a ratio of 1:1. Adolescents allocated to leisure activities will get the opportunity to participate in aerobic exercise after the evaluation at 13 weeks and at a one-year follow up.

2. Control group justification By using leisure activities in a group setting as a control group, the investigators control for the possible effect on social interaction and behavioural activation.

3. Study setting The study will be conducted at the child and adolescent psychiatric clinic in Halmstad. The site is the only provider of specialised care for adolescent depression in a small city with surrounding countryside with about 7500 adolescents. Outcome variables are assessed by communicating with patients on smart phones. Research interviews will be recorded video calls, and self-rated measures will be collected electronically.

4. Power analysis Not applicable in a pilot trial

5. Data collection QIDS-A17-SR and K-SADS-PL with the adolescent and parent will be conducted at the clinic before baseline. CDRS-R, QIDS-A17-C and CGAS at baseline, 13 weeks, 26 weeks (for controls that exercise after the initial 12 weeks) and one- year follow up assessment will be conducted through a recorded video call. Patients fill out a web based questionnaire with QIDS-A17-SR and ORS every two weeks during the 12 weeks intervention period and monthly during the follow-up until one year.

6. Screening and recruitment procedures The investigators will recruit patients from child and adolescent psychiatric outpatient care in Halmstad diagnosed with depression and who have had at least three visits and thus most likely have received some basic psychosocial interventions. The patients will be identified through a scanning of the outpatient computer system or identified by staff.

7. Randomisation, enrolment and masking. Participants will be randomized at a ratio of 1:1 to aerobic group exercise or group leisure activities. Sealed envelopes with randomisation numbers will be stored in a locked cabinet. Randomization will occur in slots of 8 patients to give equally sized groups if full inclusion is not possible within the set time frame.

The investigator (TC) conducting the baseline and 13 week evaluation will be blind to treatment allocation. The outcome measures are identical for the two groups, ensuring that the assessors remain blind. Participants will be reminded at the start of each interview not to reveal their arm of allocation. To measure blinding integrity, the assessor will record whether the participating families inadvertently reveal their group allocation. At the one-year open follow up, all patients have had the opportunity to exercise and the evaluation is unblinded.

8. Rater training Research TC will get instructions and perform CDRS-R supported by an experienced user of CDRS-R including rating and discuss four recorded videos.

9. Baseline assessments Clinician video evaluation: CDRS-R, QIDS-A17-C, CGI and C-GAS CDRS-R, QIDS-A17-C and C-GAS will be conducted through a recorded video call. Inter rater test will be performed between RW, TC and PI on ten CDRS-R, C-GAS and QIDS-A17-C from baseline.

• Self-reported web based: QIDS-A17-SR and ORS

• Parent cost evaluation with Tic-P

• Measures at site: aerobic capacity, muscular strength and body composition.

• Blood sampling

10. Recurrent evaluation. QIDS-A17-SR and ORS will web-based be filled in every other week. After two weeks of intervention also questions on safety, side effects and treatment credibility.

11. 13 week evaluation

• Clinician video evaluation: CDRS-R, CGI and C-GAS

• Self-reported web based by ES-maker: QIDS-A17-SR and ORS

• Parent rated and web-based cost evaluation with Tic-P

• Qualitative interviews with participants according to interview guide

• Anthropometric measures at site: height, weight, aerobic capacity, muscular strength and body composition.

• Blood sampling

12. End of trial. The trial will end when the final data from the one-year follow up has been collected for the last patient.

13. Participant withdrawal. Participants are free to withdraw from the trial at any point. After the withdrawal, participants will not be requested to complete any further measures, but will be asked to provide non-obligatory feedback regarding their reason for withdrawal Once participants have withdrawn from the trial, it will not be possible to re-enter or resume treatment. Withdrawn patients will not be replaced in the trial.

14. Concomitant interventions. Medication for depression is required to have been stable four weeks prior to inclusion. Medications with stimulants or neuroleptics need to have been stable for two weeks. Additionally, the participants are encouraged not to alter his/hers medication or receive any psychological treatment until after the 13 week evaluation. Visits for safety evaluations, for school-planning and to issue parental child-sick leave are permitted.

15. Data management. All aspects of data management of the trial will comply with the General Data Protection Regulation (GDPR). Notes will be made in the clinical records.

16. Statistical analyses. Statistical Package for the Social Sciences (SPSS) version 24 will be used for analyses. Multilevel regression modelling will be performed to quantify the treatment effects on the change scores from baseline measures with included explanatory variables.

17. Adverse events.

Serious Adverse Event (SAE) is any unfortunate occurrence that:

• results in death

• is life-threatening

• requires hospitalisation

• results in persistent or significant disability or incapacity

• is otherwise considered medically significant by the investigator

Suspected Unexpected Serious Adverse Reaction (SUSAR) is any SAE that is deemed to be:

• related to the trial intervention AND

• unexpected AND

• Not listed in the protocol as an expected adverse event of the intervention Expected adverse events

The investigators have considered the following events as possible adverse events:

• Increased depressive symptoms

• Suicide attempt

• Increased stress due to time consuming sessions and transportation

• Injuries due to exercise The investigators also have to consider that psychological adverse events may also be symptoms of the underlying condition, i.e. depressive disorder, rather than the intervention itself.

The assessment of the relationship between adverse events and the administration of the treatment is a decision based on all available information. The final decision is taken by the PI. If the event is a result of the administration of any of the research procedures then it will be classified as related.

If the event has been listed in the protocol as an expected side effect of the intervention then the event will be classified as expected. If the event is not listed then it will be classified as unexpected.

All adverse events will be noted by the trial coordinator in a specific log (including date, recorded clinical symptoms, and a brief description of the event). SAEs and SUSARs will be recorded in the trial coordinator's log. Appropriate action will be taken in the case of SAE and SUSAR, making sure the participant will get in contact with suitable health care services. Events will be considered as potentially treatment-related up to the 13 weeks evaluation and for the control group up to 26 weeks, where the reporting of adverse events will terminate.

18. Notification of serious breaches to GCP and/or the protocol

A "serious breach" is defined as a breach which is likely to a significant degree affect:

• the safety or physical or mental integrity of participants or

• the scientific value of the trial. The PI will notify the Ethical Review Board in writing of any serious breach. Reports of serious breaches will contain when the breach occurred, the location, who was involved, the outcome and any information given to participants. An explanation regarding the cause of the serious breach will be given, and the Ethical Review Board will be informed of planned further actions.

19. Data sharing The investigators will not share trial data with other researchers around the world.

20. Ethical considerations The study has been approved by the National Ethical Review Board in Sweden. All patients and parents will be provided by oral and written information about the study. Informed consent in writing will be provided from patients and parents to participants below 15 years of age.

Participants randomised to leisure activities will get the opportunity to exercise after 13 weeks, ensuring all participants are offered the active treatment.

21. Implications Aerobic group exercise can, if shown to be effective, become a recommended treatment option for major depressive disorder in adolescents either alone or as an addition to present treatment options with cognitive behavioural therapy and antidepressants.

Intervention

Behavioral:
• Aerobic exercise in group
Progression The goal with every new week should be making every workout a little bit harder than the week before. Strength sessions Week 1-6: 12-18 reps x 2 set per exercise and muscle 30 s rest between exercises Week 7-12: 10-12 reps x 3 set per exercise and muscle 20 s rest between exercises Adding weight with gym equipment or changing body position in the exercises to succeed with the rep scheme and making it harder as the group develop their physical and mental ability. Conditioning sessions Week 1-6: 75 seconds work time x 1 set per exercise 30 seconds of rest between exercises Week 7-12: 50 seconds work time x 2 set per exercise 20 seconds of rest between exercises Mixed sessions Week 1-6: 35 s work time per exercise 25 s rest between exercises x 2 rounds Week 7-12: 45 s work time per exercise 15 s rest between exercises x 2 rounds
• Group sessions with leisure activities
The control group will receive leisure activity in a group setting for one hour three times a week for 12 weeks. The sessions will be held at the same weekdays and about the same hours as the exercise group sessions. The same group leaders as in the exercise sessions will participate in leisure sessions and will support the adolescents through reminders and reassurance before and during the sessions to enhance adherence. The sessions will start with a check in on feelings, recent events and difficulties (i.e. supportive listening but not any interventions) followed by non heart rate increasing activities, such as playing games or watching movies together.
