Brief Summary

This clinical trial aims to evaluate the safety and effectiveness of an intervention involving parental training in behaviour management and medication in children with both Type 1 Diabetes (T1D) and Attention Deficit Disorder with Hyperactivity (ADHD). ADHD is a neurodevelopmental disorder that affects around 5% of school-age children and adolescents, while T1D is a chronic disease requiring strict management.

After initial parental training provided for parents/legal guardians, the children will be randomized to one of two cross-over groups, and treated with either lisdexamfetamine or methylphenidate first. After dose optimization for first 5-7 weeks, patients will be treated for 6 months total, after which they will be switched to the other drug.

Researchers will then compare the ADHD symptom severity as measured by Conners 3 questionnaire, and compare the frequency of any adverse events associated with the therapy. As secondary outcomes, patient's T1D control and quality of life will be compared between the two drugs.

Detailed Description

This is a multicenter, randomized, open-label, cross-over 2nd phase clinical trial in children and adolescents with attention deficit disorder with hyperactivity (ADHD) and type 1 diabetes mellitus (T1D), conducted in four Polish reference pediatric diabetes centers that together provide care for around 25% of Polish pediatric population with T1D.

T1D is a chronic pediatric disorder that requires intensive treatment with subcutaneous insulin, constant monitoring and frequent decision-making from the patient. Its course may be further complicated by comorbidities such as ADHD, which is present in around 5% of general population and reportedly more common in those with T1D. Despite the recognized need for psychiatric screening in children with T1D, ADHD often remains undiagnosed and untreated, resulting in worse therapy adherence and glycemic control, as well increased risk of life-threatening acute diabetes complications.

Each patient will begin the trial starting with the enrollment appointment, followed by a baseline assessment by a diabetologist and a psychological evaluation. After 2-weeks preliminary observation period, the parents/legal guardians of the patient will start a cycle of 10 meetings (one every week, 90 minutes long). Patients will be enrolled in an online once-weekly parental training in behavior management (PT) for ten weeks. The PT will be carried out in small groups (4-6 families per session) and conducted by a qualified and experienced PT therapist and supplemented with homework and educational materials. Qualification for pharmacological treatment will be carried out for those patients who complete the entire PT cycle, defined as the presence of at least 8 out of 10 meetings confirmed by the trainer. This is the designated expert threshold at which an intervention can be considered as carried out correctly. If the parents/legal guardians do not hold the required number of meetings, they will be allowed to make up for the missing classes during the next series of meetings with another group. If the parents/legal guardians do not attend the missing activities during this trial, the child will be excluded from the study.

After completion of PT, each participant will repeat the psychological evaluation to assess the effects of PT intervention alone on ADHD symptoms severity. Those with sustained clinically-significant ADHD symptoms will be qualified for pharmacological intervention. The patient's will be evaluated on diabetologists visit for contraindications to pharmacotherapy, including urine tests (pregnancy and panel test for substance use), ECG with QT segment assessment (to exclude long QT syndrome) and ophthalmological consultation (to exclude glaucoma). Subsequent and final assessment and qualification will be performed by psychiatrist during the nearest online consultation, after which patients will be randomized to pharmacotherapy groups: methylphenidate (MPH, long-release capsule, standard of care) versus lisdexamfetamine (LDX, investigated treatment).

Dose escalation for each drug will be performed over three (up to four) psychiatric consultations during the initial 5-7 weeks. LDX will be started with 30mg once-daily, administered orally, with dose change increment of 20mg every (after 1st, 3rd, 5th and 7th week, to the maximum of 70mg). MPH will be started with 18mg once-daily, administered orally, with dose change incremental of 18mg (after 1st, 3rd, 5th and 7th week, to the maximum of 54mg).

After the maximum tolerated dose is established, patients will continue pharmacotherapy for 6 months. During that time, treatment safety and efficacy will be evaluated twice - after first 3 months by psychological and diabetes care team's evaluation (with small dose adjustments allowed) and after full course (6 months) of therapy. On-demand psychiatric consultations will be allowed. In addition, during both diabetologists visits each participant will donate a dry blood sample for evaluation of the concentration of an allocated drug, and another sample will be self-collected on the day of the final psychological assessment for that arm to ensure that endpoint measurements are not biased by incidental non-adherence. After the last evaluation, participants will return the unused drug to their diabetes care center and will begin a wash-out period. and the treatment will continue for 6 months.

Qualification for the second arm of pharmacotherapy will be based on the same procedures and consultations which will be performed in parallel with the last diabetologists assessment (this means the participant will be on the drug at that time). Final switch and start of the second drug (LDX or MPH) will be based on psychiatrist decision. Its dose adjustment, safety and efficacy monitoring will follow the same procedures over the next 6 months.

The trial primary endpoint (ADHD symptom severity) will be assessed using the Conners 3.0 questionnaire by an investigator blinded to current treatment. Secondary endpoints will include metabolic control assessed with HbA1c and continuous glucose monitoring, and Quality of Life (QoL, measured by PedsQL). Exploratory endpoints will include school attendance, physical activity and sleep parameters (measured with personal wrist activity monitor), change in ADHD symptoms and diabetes control after PT alone, and change in rate of diabetes complications (severe hypoglycemia and diabetic ketoacidosis - rate and associated length of required inpatient treatment).

The primary goal of the trial is to improve ADHD treatment in children with T1D, and assess if treatment efficacy with lisdexamfetamine compared to methylphenidate may lead to both the psychiatric and metabolic benefits. The trial will provide patients with coordinated T1D and ADHD care, access to ADHD medication and PT (MPH is only partially reimbursed in Poland, LDX is unavailable on the Polish market, and PT is not reimbursed in the standard care).
