Plain English Summary

Background and study aims
Attention deficit hyperactivity disorder (ADHD) is a common disorder that affects behaviour. ADHD can present in a number of ways, but common symptoms include a short attention span, restlessness, hyperactivity and impulsiveness. These symptoms often overlap with and could be better explained by other common mental health disorders seen in offenders. A particular concern for children with ADHD is the high risk for developing antisocial behaviour during adolescence and young adulthood. Previous studies have shown that around 30% of adolescent and 26% of adult prisoners have ADHD. Currently, the drug methylphenidate is the first line treatment recommended for ADHD with severe impairment in the UK. Despite known effects of methylphenidate on ADHD symptoms, it is uncommon for offender mental health teams to diagnose and treat ADHD. The reason is uncertainty over the effects of methylphenidate on ADHD and behavioural outcomes in offender populations, where ADHD is often accompanied by conduct problems, substance abuse and stress related disorders. The aim of this study is to investigate the effects of methylphenidate in young male prisoners with ADHD.

Who can participate?
Male prisoners aged between 16 and 25 years with ADHD.

What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group are treated with a placebo (dummy pill) for eight weeks. Those in the second group are treated with methylphenidate for eight weeks. This involves gradually increasing the dose to find the best balance of symptom improvement against side effects for the first five weeks and then maintaining the dose for a further three weeks. At the start of the study and then after eight weeks, participants complete a number of questionnaires in order to find out if their ADHD symptoms, well-being and attitudes towards violence have changed. The prison officers and education staff also complete a questionnaire to find out if the prisoner’s level of aggressive behaviour has changed.

What are the possible benefits and risks of participating?
Study participants may benefit from receiving the diagnosis of ADHD and treatment for the disorder, as all participants will be offered treatment once the 8 week trial is completed. Common side effects from medication such as appetite reduction and sleep disturbance are usually minor and reduce with time, but can lead to some participants withdrawing from treatment. Serious side effects are rarely reported in ADHD treatment trials and so are likely to be rare and unexpected.

Where is the study run from?
The study is run from King’s College London and takes place in two prisons, one in England and one in Scotland (UK)

When is the study starting and how long is it expected to run for?
May 2014 to August 2019

Who is funding the study?
This project is funded by the Efficacy and Mechanism Evaluation (EME) programme, a partnership between the Medical Research Council (MRC) (UK) and the National Institute for Health Research (UK). Janssen-Cilag Ltd. supplied Concerta XL

Scientific title

Randomised controlled trial of the short term effects of OROS-methylphenidate on ADHD symptoms and behavioural outcomes in young male prisoners with attention deficit hyperactivity disorder

Acronym

CIAO-II

Study hypothesis

Current study hypothesis as of 22/01/2021:
The overall aim of the trial is to investigate the effects of Methylphenidate extended release (OROS MPH) in young male prisoners (age 16-25) meeting DSM-5 diagnostic criteria for ADHD.

Hypotheses:
1. OROS-MPH is better than placebo in reducing inattention and hyperactivity-impulsivity in young male prisoners meeting diagnostic criteria for DSM-5 ADHD
2. OROS-MPH is better than placebo at reducing secondary outcomes that are key indicators of behavioural and functional impairments used in the management of young prisoners in the UK (including emotional dysregulation, antisocial behaviour in the prison, violent attitudes)
3. Improvements in secondary behavioural outcomes due to OROS-methylphenidate are mediated by improvements in ADHD symptoms or emotional dysregulation

Previous study hypothesis:

Intervention

Current interventions as of 22/01/2021:
Participants will be randomised to receive 8-weeks treatment with either OROS-MPH or placebo, titrated over 5 weeks to balance ADHD symptom improvement against side effects and then maintained for a further 3 weeks. 200 participants will be recruited with 1:1 ratio of drug to placebo. Randomisation will be conducted by the King’s CTU with blinding of both investigators and participants.

Randomisation will take place once informed and signed consent has been obtained, eligibility checks have been completed and before the treatment is started. We will use the King's Clinical Trials Unit’s Independent Randomisation Service, ensuring reliability and credibility in the randomisation process. Random block sizes will be used to control the numbers of subjects allocated to each group, stratified by site and in a 1:1 drug-placebo ratio. Patient characteristics will not be taken into account in the randomisation process, but we expect a balanced ratio of cognitive ability, ADHD symptom severity and co-occurring psychosocial and mental health problems across the drug treatment and placebo groups.

Both active medication (Concerta XL 18 mg tablets) and matched placebo will be titrated weekly for 5 weeks and then kept at stable maintenance dose for 3 weeks. The maximum titrated dose (or matching placebo) is as follows: Week 1 = 18 mg (1 tablet); Week 2 = 36 mg (2 tablets); Week 3 = 54 mg (3 tablets); Week 4 = 72 mg (4 tablets); Week 5 = 72 mg (4 tablets); Week 6 = 72 mg (4 tablets); Week 7 = 72mg (4 tablets); Week 8 = 72mg (4 tablets). Titration of dose is conducted by the study psychiatrist. Both the trial investigators and participants are blinded. The titration protocol is followed in the same way for both active medication (IMP) and placebo. Treatment will start at an initial dose of 18 mg (1 tablet) for 1 week, and be increased weekly in 18 mg increments to a maximum of 72 mg (4 tablets) (i.e. 18 mg (1 tablet), 36 mg (2 tablets), 54 mg (3 tablets) and 72 mg (4 tablets). Medication will be reduced by 18 mg (1 tablet) if there is a limiting adverse event, in which case there will be no further increase in medication for the duration of the trial. Medication may be provided either once or twice daily up to the maximum daily dose. Titration upwards will be stopped if all 18 ADHD symptoms are scored as negligible (score of 0 or 1 on the CAARS-O) or absent. Unacceptable levels of adverse effects on the lowest dose of 18mg might lead to a cessation of treatment in a few cases; if this occurs we will ask participants to remain in the trial for the remaining trial assessments.

Participants in both groups are followed up at eight weeks.
