Detailed Description
Rationale:
Preservation of residual pancreatic beta cell function in children with newly diagnosed T1D gives a chance for better diabetes control, reduction of chronic diabetes complications, and possibly temporary insulin withdrawal. Indication of a cheap drug for secondary prevention of T1D.
Setting:
Recruitment will be through the paediatric diabetes clinics at two participating centres in Warsaw, Poland (Department of Paediatrics, the Medical University of Warsaw and Department of Endocrinology and Diabetology, Children's Memorial Health Institute).
The initiation of study treatment may be performed no later than 28 days after screening visit, and no later than in 8 weeks from diabetes diagnosis.
PICO:
Adolescent participants meeting inclusion criteria, newly diagnosed with type 1 diabetes will be randomly assigned to two groups, receiving either fenofibrate at a dose of 160 mg or placebo, and regularly assesed, every 3 months for the next year. Assuming increase by 50% of AUC of C-peptide in the test group compared to placebo, 88 subjects are needed to achieve power of 85%. If about 13% drop-out is assumed the total group size is 102 patients. Given randomization ratio 1:1, there is 51 patients in each group.
Main study procedures:
- Demographic and medical history.
- Physical examination and vital signs: heart rate and blood pressure, respiration rate, body temperature.
- Blood collection for laboratory analysis (hematology: morphology with automatic blood smear, biochemistry: ALT, AST, total bilirubin, albumin, amylase, lipase, total cholesterol, HDL, LDL, triglycerides, GGTP, HbA1c, TSH, FT4, Anti-Tg, Anti-TPO, CK, creatinine, urea, vitamin D, homocysteine, Anti-tTG IgA, IgA.
- Urine pregnancy test (in girls with childbearing potential).
- C-peptide and Glucose in MMTT stimulation assay.
- Anti-insulin IAA antibodies, Antibodies to glutamic acid decarboxylase (GADA), Antibodies to tyrosine phosphatase (IA2A), Antibodies to the zinc transporter 8 (ZnT8).
- IL1, IL2, IL10.
- TNF alpha, IFN gamma.
- Genetic study - WES genome sequencing, HLA DR3, DR4, DO8, DQ7.
- FGM Libre Free Style Glucose Monitoring System.
- Abdominal ultrasound.
- Ultrasound of the thyroid gland.
- Safety monitoring and AE collection.
- IMP administration. Compliance will be assessed by collecting empty packages as well as by direct interview and participants receiving <75% of the recommended doses will be considered as non-compliant.

Accepts Healthy Volunteers
Description
Inclusion Criteria:
Subjects who meet all of the following criteria are eligible to participate in this study:
Subject or Legally accepted representative (LAR) able to understand and provide signed informed consent. Assent is also required of adolescents and children.
- LAR of subjects ≤ 17 years sign the "Information Leaflet and ICF for the Parent/Legal Guardian of Minor Subject".
- Adolescents from 10-15 years sign "Children Assent form".
- Adolescents from 16-17 years sign "Adolescent Assent form".
- Age ≥10 and ≤ 17 years.
Diagnosis of type 1 diabetes within 8 weeks before randomization (V0 visit) based on positive autoantibody (minimum 1 among: GADA, IA2A, ZnT4, IAA) and symptoms of type 1 diabetes according to the criteria of the Polish Diabetes Association (1 of the following):
- symptoms of diabetes and blood glucose ≥ 200 mg / dl (≥ 11.1 mmol/l),
- when no symptoms or when diabetes symptoms are present and random glucose <200 mg/dl (<11.1 mmol/l) - then confirmation of the diagnosis is fasting blood glucose in 2 measurements ≥ 126 mg/dl (≥ 7.0 mmol/l); each test must be performed on a different day,
- in the absence of symptoms of hyperglycaemia and random glycaemia ≥ 200 mg/dl (11.1 mmol/l), fasting glucose ≥ 126 mg/dl (7.0 mmol/l) is a confirmation of the diagnosis,
- if once or twice fasting blood glucose is 100-125 mg / dl (5.6-6.9 mmol/l), or if fasting blood glucose is below 100 mg/dl (5.6 mmol/l) ) exists, If there is a reasonable suspicion of impaired glucose tolerance or diabetes mellitus, an oral glucose tolerance test (OGTT) should be performed. At the 120th minute of the OGTT, blood glucose ≥ 200 mg/dl (11.1 mmol/l) confirms the diagnosis of diabetes.
Male or nonpregnant and nonlactating female who is abstinent or agrees to use effective contraceptive methods throughout the course of the study. Acceptable birth control methods are the following:
- Intrauterine device in place for at least 3 months.
- Use of condom or diaphragm with spermicide for at least 14 days prior to the Visit 0 visit and through study completion.
- Stable hormonal contraceptive for at least 2 months prior to the Visit 0 and continuing through study completion.
- Females (menstruating) must have a negative urine beta-human chorionic gonadotropin hormone (hCG) pregnancy test at Visit 0.

Safety will be evaluated through assessment of AEs, vital signs, physical examinations, USG findings, and laboratory evaluations.
Any clinically significant laboratory occurring after study drug initiation must be reported by the investigator as an AE and/or SAE, as appropriate, and must be followed by additional laboratory evaluations until they return to normal range, stabilize, or until the change is no longer clinically relevant.
All safety analyses will be conducted using the Safety Analysis Set.
Adverse event data will be presented and tabulated according to MedDRA classification.
