Objectives
The primary objective of this study is to evaluate the efficacy of cagrilintide 2.4 mg administered subcutaneously once weekly as monotherapy, and the combination of cagrilintide and semaglutide (CagriSema) 2.4 mg/2.4 mg administered subcutaneously once weekly, for weight management in children and adolescents with overweight or obesity. The study aims to confirm the superiority of these interventions compared to a placebo.
Secondary objectives include:
- Confirmation of the superiority of CagriSema 2.4 mg/2.4 mg subcutaneously once weekly compared to semaglutide 2.4 mg subcutaneously once weekly regarding weight management.
- Assessment of the safety and pharmacokinetics of the investigated treatments.
Participants
This clinical trial involves a total of 303 participants diagnosed with obesity and type 2 diabetes. The study population consists of male and female pediatric patients aged 8 to <18 years. Selection is based on a body mass index corresponding to the ≥95th percentile for children aged 8 to <12 years, or the ≥95th percentile, or the ≥85th percentile with an obesity-related complication, for adolescents aged 12 to <18 years. Eligible individuals must have a body weight greater than 45 kg and a history of at least one unsuccessful attempt to lose weight through a structured lifestyle modification program involving diet and exercise counseling for a minimum of 3 months. Participants may be receiving a lifestyle intervention or stable treatment with metformin. Inclusion requires HbA1c levels ≤10.0% and specific laboratory parameters for total calcium, phosphate, alkaline phosphatase, and parathyroid hormone within normal ranges.
Plans and Procedures
This Phase III clinical trial is designed to evaluate the efficacy, safety, and pharmacokinetics of cagrilintide administered as a monotherapy and in combination with semaglutide (CagriSema) for weight management. The study focuses on children and adolescents presenting with obesity or overweight, including those with type 2 diabetes. Participants are expected to receive subcutaneous injections once weekly. The research methodology involves comparing the test products against a placebo to confirm superiority in weight management outcomes. The primary endpoint is the relative change in body mass index from baseline to the end of the 68-week treatment period. The study sequence includes a screening visit to assess eligibility through body mass index percentile calculations, laboratory parameters, and HbA1c levels, followed by the treatment phase and an end-of-study assessment. Total participant involvement in the treatment phase is expected to last 68 weeks.
Treatment
Cagrilintide semaglutide is an experimental medication administered as a solution for injection via the subcutaneous route. The dosage is 2.4 mg of cagrilintide and 2.4 mg of semaglutide, provided on a once weekly schedule.
Cagrilintide is an experimental medication administered as a solution for injection via the subcutaneous route. The dosage is 2.4 mg, provided on a once weekly schedule.
Semaglutide is a comparator treatment administered as a solution for injection via the subcutaneous route. The dosage is 2.4 mg, provided on a once weekly schedule.
Placebo is utilized in the study as a non-experimental treatment.
Efficacy
The primary efficacy endpoint is the relative change in body mass index (BMI) from baseline at week 0 to the end of treatment at week 68, expressed as a percentage. Secondary efficacy parameters include:
- Relative change in body weight from baseline to week 68, expressed as a percentage.
- Change in BMI Standard Deviation Score (SDS) from baseline to week 68.
- Reduction in weight category from baseline to week 68, measured by the count of participants.
Inclusion and Exclusion Criteria
Inclusion Criteria
- Informed consent of parent(s) or legally acceptable representative (LAR) of participant and child assent, as age-appropriate, obtained before any study -related activities. Study -related activities are any procedures that are carried out as part of the study, including activities to determine suitability for the study. a. The parent(s) or LAR of the child must sign and date the Informed Consent Form (according to local requirements) b. The child must sign and date the Child Assent Form or provide oral assent (according to local requirements).
- Male or female.
- Aged 8 to <18 years at the time of signing the informed consent.
- Body mass index (BMI), at screening, corresponding to: a. ≥95th percentilea for children aged 8 to <12 years (Tanner stage 1-5) b. ≥95th percentilea or ≥85th percentilea with the presence of at least one obesity-related complication including, but not limited to, type 2 diabetes (T2D), hypertension, dyslipidaemia or obstructive sleep apnoea for adolescents aged 12 to <18 years (Tanner stage 2-5).
- Laboratory parameters, as measured by the central lab at screening, within normal sex- and age-specific ranges of total calcium, phosphate, alkaline phosphatase, parathyroid hormone.
- History of at least one unsuccessful effort to lose sufficient body weight after participation in a structured lifestyle modification programme (diet and exercise counselling) for at least 3 months.
- Body weight >45 kg at screening.
- HbA1c ≤10.0% (86 mmol/mol) as measured by central laboratory at screening.
- Treatment with lifestyle intervention or treatment with metformin according to local label. Treatment with metformin should be stable (same dose and dosing frequency) for at least 56 days before screening.
Exclusion Criteria
- Treatment with any medication prescribed for obesity or weight management within 90 days before screening.
- Previous or planned (during the study period) obesity treatment with surgery or a weight loss device. However, the following are allowed: Liposuction and/or abdominoplasty, if performed >1 year before screening. Adjustable gastric banding, if the band has been removed >1 year before screening. Intragastric balloon, if the balloon has been removed >1 year before screening. Duodenal-jejunal bypass liner (e.g., Endobarrier), if the sleeve has been removed >1 year before screening.
- Uncontrolled thyroid disease.
- Endocrine, hypothalamic, or syndromic obesity.
- A self-reported (or by parent(s)/LAR, where applicable) change in body weight >5% within 90 days before screening irrespective of medical records.
- Type 1 diabetes or monogenic diabetes.
- HbA1c ≥6.5% (≥48 mmol/mol) as measured by the central laboratory at screening.
- Treatment with glucose -lowering agent(s) prescribed for the indication of diabetes or pre-diabetes within 90 days before screening.
- Known hypoglycaemic unawareness as indicated by the investigator according to Clarke’s questionnaire, question 8.
- Recurrent severe hypoglycaemic episodes within 1 year before screening, as judged by the investigator.
- Positive insulinoma associated protein-2 (IA-2) antibodies or anti-glutamic acid decarboxylase (anti-GAD) antibodies.
- Treatment with any medication for the indication of diabetes other than those stated in the inclusion criteria within 90 days before screening.
- Uncontrolled and potentially unstable diabetic retinopathy or maculopathy. Verified by a fundus examination performed within 90 days before screening or in the period between screening and randomisation. Pharmacological pupil-dilation is a requirement unless using a digital fundus photography camera specified for non-dilated examination.
