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   43839   clinical trials with a EudraCT protocol, of which   7280   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
    The primary objective is to evaluate the efficacy of avacopan compared to avacopan-matching
    placebo based on histologic changes in kidney biopsies taken before and during treatment.
    E.2.2Secondary objectives of the trial
    The secondary objectives of this study include evaluation of:
    1. The safety of avacopan compared to avacopan-matching placebo based on the incidence
    of adverse events, changes in clinical laboratory measurements, and vital signs;
    2. Changes in laboratory parameters of renal disease including estimated glomerular
    filtration rate (eGFR), proteinuria, and urinary excretion of monocyte chemoattractant
    protein-1 (MCP-1) with avacopan compared to placebo;
    3. Health-related quality-of-life changes based on Short Form-36 version 2 (SF-36 v2) and
    EuroQOL-5D-5L (EQ-5D-5L) with avacopan compared to placebo;
    4. The pharmacokinetic profile of avacopan in patients with C3G.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Biopsy-proven C3G, either DDD or C3GN, with or without a renal transplant, and with the
    following observations upon renal biopsy taken within 12 weeks prior to screening or during
    a. 2 levels of magnitude greater staining of C3 than any combination of IgG, IgM, IgA,
    kappa and lambda light chains, and C1q by immunohistochemistry, and
    b. Evidence of proliferative glomerulonephritis (mesangial hypercellularity of greater than 3
    mesangial cells per mesangial area and/or endocapillary hypercellularity
    defined as an increased number of cells within glomerular capillary lumina, causing
    luminal narrowing) based on light microscopy, and
    c. Confirmation of the presence of electron dense deposits in the glomeruli on electron
    microscopy corresponding with the C3 immunofluorescence positivity.
    The site will use their site-specific standard technique for taking the biopsy, which can include
    ultrasound guidance.
    2. Male or female patients, aged at least 18 years may be enrolled; female patients of childbearing
    potential (i.e., those who have experienced menarche and who are not permanently sterile or
    postmenopausal, defined as at least 12 consecutive months with no menses without an alternative
    medical cause) may participate if adequate contraception is used during and for at least the three months after study completion; Male patients with partners of childbearing potential may
    participate in the study if they had a vasectomy at least 6 months prior to randomization or if
    adequate contraception is used during and for at least the 3 months after study completion; male
    patients with partners of childbearing potential must be excluded if they plan to father a child
    during the study. Adequate contraception is defined as resulting in a failure rate of less than 1% per
    year (combined estrogen and progestogen [oral, intravaginal, or transdermal], or progestogen-only
    hormonal contraception (oral, injectable, or implantable), intra-uterine device, intra-uterine
    hormone releasing system, bilateral tubal occlusion, vasectomized partner, or true sexual
    abstinence, i.e., in line with the preferred and usual lifestyle of the patient); In addition, a barrier
    method (i.e., cervical cap, diaphragm or condom) must be used during intercourse between a male
    patient and a female of child-bearing potential.
    3. Willing and able to give written Informed Consent and to comply with the requirements of the
    study protocol.
    4. Judged to be otherwise fit for the study by the Investigator, based on medical history, physical
    examination, immunization history and clinical laboratory assessments. Patients with clinical
    laboratory values that are outside of normal limits (other than those specified in the Exclusion
    Criteria) and/or with other abnormal clinical findings that are judged by the Investigator not to be
    of clinical significance, may be entered into the study.
    E.4Principal exclusion criteria
    1. Pregnant or nursing;
    2. Tubulointerstitial fibrosis appears to be more than 50% based on standard assessment using
    trichrome staining of the renal biopsy;
    3. Use of eculizumab or another anti-C5 antibody within 26 weeks prior to dosing;

    local recurrence or metastasis;
    7. Positive HBV, HCV, or HIV viral screening test indicative of acute or chronic infection;
    8. Evidence of tuberculosis based on interferon γ release assay (IGRA), or tuberculin purified protein
    derivative (PPD) skin test.
    9. Active uncontrolled infection;
    10. WBC count less than 3500/L, or neutrophil count less than 1500/L, or lymphocyte count less

    anticoagulant use that cannot be temporarily reversed; other coagulopathies).
    E.5 End points
    E.5.1Primary end point(s)
    The percent change from baseline to Week 26 in the C3G Histologic Index for disease activity
    E.5.1.1Timepoint(s) of evaluation of this end point
    Week 26
    E.5.2Secondary end point(s)
    Secondary efficacy endpoints include:
    1. The proportion of patients who have a histologic response, defined as a decrease
    (improvement) in the C3G Histologic Index for disease activity of at least 35% from
    baseline to Week 26 (see Section 8.8 for basis of selection of 35% threshold);
    2. The percent change from baseline in the C3G Histologic Index for disease chronicity
    over the placebo-controlled 26-week treatment period.
    Other efficacy endpoints include:
    1. The change and percent change from baseline in eGFR over the placebo-controlled 26-
    week treatment period;
    2. The percent change from baseline in UPCR over the placebo-controlled 26-week
    treatment period;
    3. The percent change from baseline in urinary MCP-1:creatinine ratio over the placebocontrolled
    26-week treatment period;
    4. Change from baseline in EQ-5D-5L (visual analogue scale and index) and SF-36 v2
    (domains and component scores) over the placebo-controlled 26-week treatment period.

    Safety endpoints include:
    1. Patient incidence of treatment-emergent serious adverse events, adverse events, and
    withdrawals due to adverse events;
    2. Change from baseline and shifts from baseline in all safety laboratory parameters;
    3. Change from baseline in vital signs.

    PK endpoints
    Avacopan (and its metabolite CCX168-M1) plasma concentration results for both C5b-9 level
    strata combined will be used to calculate trough plasma concentrations (Cmin) over the course of
    the clinical trial. When possible, the terminal elimination half-life will also be calculated.

    PD endpoints
    The following PD endpoints may be assessed:
    1. Change and percent change from baseline in plasma biomarkers such as inflammatory
    cytokine and chemokine levels.
    2. Change and percent change from baseline in urine biomarkers such as urinary
    sCD163:creatinine ratio, inflammatory cytokine and chemokine levels;
    3. Change from baseline in CBC count (especially WBCs, neutrophils, and lymphocytes)
    and lymphocyte subset counts including B cells, T cells, and natural killer cells;
    4. The relationship between PK parameters and renal function based on eGFR will be
    evaluated. The data may also be used to evaluate the PK/PD relationship of avacopan
    treatment for both C5b-9 level strata separately as well as combined. To this end, the
    change and/or percent change from baseline in the C3G Histologic Index, UPCR, eGFR,
    urinary MCP-1:creatinine ratio, and other biomarkers may be used as PD markers.
