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   43865   clinical trials with a EudraCT protocol, of which   7286   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.

    Title: Effect of administration of Oxalobacter formigenes on the stability and structure of fecal bacterial populations in humans

    Date: 26 June 2007

    Version: 001
    E.3Principal inclusion criteria
    1. The subject (or legally acceptable representative) must give written informed consent (and assent for subjects ≥ 12 years or country specific age as appropriate). For subjects less than 18 years of age, parent or guardian will provide informed consent and the subject will provide witnessed verbal assent

    2. Male or female subjects greater than or equal to 5 years of age

    3. Urinary oxalate excretion of > 1.0 mmol/1.73m2/day at Baseline

    4. Documentation of diagnosis of PH I or PH II by any one of the following:

    a. Liver biopsy confirmation of deficient liver specific peroxisomal alanine-glyoxylate aminotransferase, (AGT) or mislocalization of AGT from peroxisomes to mitochondria (PH I) or deficient glyoxylate reductase/hydroxypyruvate reductase (GR/HPR) activity (PH II)

    b. Homozygosity or compound heterozygosity for a known mutation in the causative genes for PH I and PH II

    c. Increased glycolate excretion for PH I or increased L-glycerate excretion for PH II


    5. Subjects receiving pyridoxine must be receiving a stable dose for at least 3 months prior to entry in to the study and must remain on the stable dose during the study. Other (non-pyridoxine naïve) subjects (e.g. Pyridoxine non-responder: <30% reduction of the urine oxalate levels) not receiving pyridoxine at study entry must be willing to refrain from initiating pyridoxine during study participation. Note: There will be no pyridoxine-naïve subjects enrolled in the study.

    6. Renal function defined as an estimated GFR ≥ 50 ml/min normalized to 1.73m2 body surface area
    E.4Principal exclusion criteria
    1. Pregnant, lactating, or actively menstruating women and women of child-bearing potential who are not using adequate contraceptive precautions. Sexually active females, unless surgically sterile or at least 2 years post-menopausal, must be using a highly effective contraception (including oral, transdermal, injectable, or implanted contraceptives, IUD, abstinence, use of a condom by the sexual partner, or sterile sexual partner) for 30 days prior to the first dose of OxabactTM and must agree to continue using such precautions during the clinical study. Note: A highly effective method of birth control is defined as one that results in a low failure rate (i.e. less than 1% per year) when used consistently and correctly, such as implants, injectables, combined oral contraceptives, some intrauterine contraceptive devices (IUDs), sexual abstinence, or a vasectomised partner.

    2. Positive serum pregnancy test

    3. Participation in any study of an investigational product, biologic, device, or other agent within 30 days prior to randomization or not willing to forego other forms of investigational treatment during this study

    4. Subjects on hemodialysis or peritoneal dialysis

    5. Subjects that have undergone transplantation (solid organ or bone marrow)

    6. Chronic gastrointestinal disease associated with enteric hyperoxaluria, e.g., history of inflammatory bowel disease, colostomy. Note: For clarity, existence of Secondary Hyperoxaluria (e.g. with cystic fibrosis, chronic inflammatory bowel diseases, short bowel syndrome and/or deficiency of intestinal oxalate-degrading bacteria is included (as an exclusion criteria).

    7. Current systemic (oral, IM, IV) antibiotic use or received systemic antibiotics within 14 days of study enrolment

    8. History of chronic, recurrent infections requiring >2 courses of antibiotics in the past 6 months

    9. History of malignancy except for basal or squamous cell skin cancer that has been excised

    10. Unable to collect 24-hour urine samples or follow other study procedures

    14. Subjects from correctional facilities or asylums.

    15. Subjects who are mentally handicapped.
    E.5 End points
    E.5.1Primary end point(s)
    The primary efficacy endpoint is the percentage change in urinary oxalate (expressed as mmole/1.73m2 /day) from Baseline to Week 24 (Day 168). The primary efficacy analysis will compare the percentage changes in urinary oxalate in the Oxabact TM and Placebo groups using a two-sided, two sample t-test. This analysis will be carried out in the efficacy population, defined as all randomized subjects who receive at least one dose of study drug and who provide at least one post-baseline measurement of urinary oxalate.
