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   43383   clinical trials with a EudraCT protocol, of which   7178   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.

    4.Has UOx excretion ≥ 50 mg/24 hr on an adequate (i.e., appropriate creatinine [mg/kg body weight] for sex) 24-hour urine collection at Screening
    5.Has at least 1 documented kidney stone (spontaneous kidney stone passage or intervention to remove kidney stone, or new or enlarged stone on imaging) within 2 years prior to Screening (See Exclusion Criterion 6)
    6.Has provided 2 adequate 24-hour urine collections at Baseline, with average UOx excretion ≥ 50 mg/24 hr (and neither is < 40 mg/24 hr)
    7.For subjects taking concomitant medication for management of kidney stone risk factors (e.g., thiazides, calcium supplements, alkali therapy, allopurinol): has been on a stable dose regimen for > 8 weeks prior to Screening, and with no changes in dosing (dose level or dosing frequency) anticipated during the first 24 weeks of the study Treatment Period
    8.For female subjects: Is either medically incapable of pregnancy (e.g., has undergone hysterectomy or tubal ligation), is otherwise permanently sterile, or is postmenopausal (defined as minimum 12 consecutive months of amenorrhea not due to an alternative medical cause) or if a woman of childbearing potential, has a negative Screening serum pregnancy test, is not pregnant or nursing at Screening, and agrees to use a highly effective method of birth control for as defined in the protocol for the duration of the study inclusive of the 1 month follow-up period.
    E.4Principal exclusion criteria
    1.Has > 30% variability in the ratio of creatinine (mg)/body weight (kg) among the 3 24-hour urine collections prior to randomization (1 at screening - 2 at baseline)
    2.Has eGFR< 30 mL/minute/1.73 m2 at Screening
    3.Cannot establish Baseline kidney stone burden per study image acquisition requirements
    4.Has a known genetic, congenital, or other cause of kidney stones (e.g., primary hyperoxaluria, cystinuria, primary hyperparathyroidism, medullary sponge kidney), or recent kidney stone (to satisfy Inclusion Criterion 5) was determined to be due to:
    - infection (e.g., struvite stone, recurrent urinary tract infections)
    - medications associated with crystalluria (e.g., carbonic anhydrase inhibitors [acetazolamide, topiramate], triamterene, protease inhibitors, guaifenesin, ephedrine, sulfonamides)
    - medications known to cause fat malabsorption (e.g. orlistat)
    5.Exclusions due to ongoing medication use at screening:

    - Chronic use of long-acting narcotic medication(s), or short-acting/immediate release narcotics at aggregate doses > 50 Morphine Milligram Equivalents (MME)/day
    - Chronic therapy with high doses of systemic steroids use (i.e., > 10 mg/day prednisone or equivalent daily) or intensification of existing immunosuppressant or immunomodulatory therapy for treatment of acute disease flare within 4 weeks prior to Screening or during Screening
    Note: Stable subjects on low chronic dose of steroids or maintenance regimens of other immunosuppressant/immunomodulatory drugs, such as transplant recipients, are not excluded
    6.Any clinically significant finding during Screening (e.g., abnormality on Baseline imaging requiring assessment or intervention, acutely decreased kidney function, or other significant laboratory abnormalities), any ongoing clinically significant illness requiring an intervention or change in management within 4 weeks prior to Screening (e.g., flare of inflammatory bowel disease), or any planned surgical/invasive procedure during the first 24 weeks of the study
    Note: Subjects may be rescreened following resolution of the condition that led them to satisfy this exclusion criterion

    8.Has received reloxaliase in any other clinical study, or participation in another drug or device clinical trial within 30 days prior to or during Screening
    9.Is not, per Investigator judgment, an ideal clinical trial candidate due to a personal issue or medical condition that is likely to impede successful study completion.
