Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   40626   clinical trials with a EudraCT protocol, of which   6627   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).
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The objectives of this study are to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and glycemic efficacy of multiple ascending doses of RZ358 administered for 8 weeks in patients with hyperinsulinemic hypoglycemia due to congenital hyperinsulinism (CHI).
    E.2.2Secondary objectives of the trial
    not applicable
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Provide written informed consent and, as applicable, assent, before any study specific procedures are performed
    2. At Screening, aged ≥2 years and ≤45 years
    3. An established clinical diagnosis, with or without a genetic diagnosis, of congenital hyperinsulinism
    4. Patient is currently receiving SOC medications (i.e corticosteroids, diazoxide, lanreotide, sirolimus, and octreotide) and/or nutritional supplementation for CHI, with at least 2 months of stable treatment; OR is not on treatment, at the time of Screening.
    5. Glucose values <70 mg/dL (3.9 mmol/L) for ≥8% of the overall monitored time and for ≥60 min per day on at least 5 of the 10 days of a 10-day Screening CGM evaluation
    Experiencing ≥ 3 hypoglycemia events (<70 mg/dL) per week by SMBG and/or according to the Investigator's evaluation.
    6. Hepatic ultrasound at Screening without clinically significant findings, gallstones or evidence of peliosis hepatitis
    7. For female patients of childbearing potential, a negative serum or urine pregnancy test within 7 days before dosing Females of childbearing potential are defined as fertile following menarche and until becoming postmenopausal or permanently sterile. Note: Postmenopausal is defined as absence of vaginal bleeding or spotting for at least 1 year. Permanently sterile is defined as having had a hysterectomy, bilateral salpingectomy, or bilateral oophorectomy.
    8. For female patients of childbearing potential, a willingness to use highly effective* contraceptive measures adequate to prevent a new pregnancy for the duration of the study, including for at least 105 days after receiving the last dose of study drug. For women with reproductive potential who use a hormonal method of contraception, concurrent use of a second (barrier) method is recommended. (*Highly effective methods of birth control are defined as those that result in a low failure rate [ie, less than 1% per year] when used consistently and correctly [eg, implants, injectables, oral contraceptives, some intrauterine devices, bilateral tubal occlusion, true sexual abstinence in line with the preferred and usual lifestyle of the patient, or vasectomized partner.])
    9. For sexually active males, a willingness to use contraceptive measures, e.g. a condom, for the duration of the study, including for at least 105 days after receiving the last dose of study drug. In addition, males must agree not to donate sperm over the same study period.
    E.4Principal exclusion criteria
    1. Any out-of-range laboratory value at Screening that has not been reviewed, approved, and documented as not clinically significant by the Investigator, with the exception of liver function tests for total bilirubin, ALT, AST, and ALP, which must be within 1.5X the upper limit of normal (ULN) for the reference range
    2. Body mass index ≥ 35 kg/m2 for patients aged 18 years and above and, for patients aged less than 18 years, BMI ≥ 95% percentile for age
    3. History of malignancy within 3 years before Screening other than carcinoma in situ of the cervix or adequately treated non-metastatic squamous or basal cell carcinoma of the skin
    4. History of seropositivity for HIV antibody, hepatitis B, or hepatitis C antibody
    5. Major general surgery within 3 months before Screening or anticipated during the study period
    6. Use of systemic corticosteroids within 30 days before Screening
    7. Known allergy or sensitivity to RZ358 or any component of the study drug
    8. Treatment with an investigational drug or device within 30 days or 5 half-lives of the investigational drug before Day 1 of Week 1, whichever is longer. Participation in registries and purely diagnostic studies is allowed.
    9. Female patients who are pregnant, planning to become pregnant during the course of the study, have recently delivered (within 3 months before Screening), or are breastfeeding
    10. Male patients who are planning a pregnancy with a female partner during the course of the study or within 105 days after administration of study drug
    11. Any organ condition, concomitant disease (eg, psychiatric illness, severe alcoholism, or drug abuse, cardiac, hepatic, or kidney disease), or other abnormality that itself, or the treatment of which, could interfere with the conduct of the study (eg, may affect absorption, distribution, metabolism, or elimination of the study drug) or that, in the opinion of the Investigator and/or Sponsor’s medical monitor, would pose an unacceptable risk to the patient in the study.
