Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   43871   clinical trials with a EudraCT protocol, of which   7290   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To demonstrate the superiority of sotagliflozin 400 mg versus placebo in the proportion of patients with glycosylated A1C <7.0% at Week 24 and no episode of severe hypoglycemia and no episode of diabetic ketoacidosis (DKA) after randomization.
    E.2.2Secondary objectives of the trial
    To evaluate the change from Baseline of sotagliflozin versus placebo in hierarchical order on the following:

    • A1C
    • Body weight
    • Systolic blood pressure (SBP)
    • Bolus insulin dose
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Objective: To evaluate satiety (appetite) in a subset of enrolled patients.

    The instrument used will be the Patient Satiety Daily Diary (PSDD). Up to 280 patients (140 per treatment group) will be recruited for this substudy.
    The patients will be instructed to complete the paper diary each day, before the first meal of the day for the last 2 weeks of the double-blind Treatment Period (ie, during Week 23 and during Week 24, a total of 14 days). The diaries will be returned to the site at the visit scheduled for the end of Week 24.
    E.3Principal inclusion criteria
    1) Patient has given written informed consent to participate in the study in accordance with local regulations

    2) Adult patients 18 years and older with a diagnosis of T1D made at least 1 year prior to informed consent

    3) Patients are being treated with insulin(s) or insulin analog(s)

    4) Non-fast acting insulin dose is stable (±20%) for 2 weeks prior to the Screening Visit

    5) At the Screening Visit, A1C must be between 7.0% and 11.0%, inclusive

    6) BMI ≥18.5 kg/m2

    7) Must be willing and able to perform SMBG and complete the study diary as required per protocol

    8) Females of childbearing potential must use an adequate method of contraception to avoid pregnancy throughout the duration of the study and for 30 days after the last dose of study drug. Females of childbearing potential include any female who has experienced menarche and who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or is not postmenopausal. Postmenopause is defined as no menses for ≥12 months without another cause. For females with questionable menopausal history (eg, irregular menstrual periods and age >40 years) a documented serum follicle-stimulating hormone (FSH) level must be ≥30 mIU/mL.

    9) Females of childbearing potential must have a negative serum or urine pregnancy test prior to the start of study drug. In the case of positive urine pregnancy testing, a negative serum sample for pregnancy testing, to confirm that the patient is not pregnant, must be obtained prior to start of study.
    E.4Principal exclusion criteria
    1) Therapies and/or medications:

    a) Use of antidiabetic agent other than insulin(s) or insulin analog(s) at the time of screening (any medication other than insulin or insulin analog used for treatment of T1D must be washed out for at least 8 weeks prior to the Screening Visit)

    b) Any prior exposure to sotagliflozin

    c) Use of SGLT inhibitors within 8 weeks prior to Screening.

    d) Chronic systemic corticosteroid use, defined as any dose of systemic corticosteroid taken for more than 4 consecutive weeks within the 6 months prior to the Screening Visit.

    2) Diabetes-related conditions:

    a) Type 2 diabetes mellitus, or severely uncontrolled T1D as determined by the Investigator

    b) History of severe hypoglycemic event within 1 month prior to the Screening Visitc) History of DKA or nonketotic hyperosmolar state within 1 month of Screening OR ≥2 episodes of DKA or nonketotic hyperosmolar state within 6 months of Screening

    2) A1C at Week 24
    3) Body weight at Week 24 (absolute and percent change)
    4) SBP at Week 16 in the subset of patients with Baseline SBP ≥130 mm Hg
    5) Bolus insulin dose at Week 24 (as an average over the 3-5 days prior to the visit)
