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   38893   clinical trials with a EudraCT protocol, of which   6392   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.

    MedDRA Classification
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    1. To evaluate the efficacy of clazakizumab in preventing all-cause composite allograft loss due to CABMR (defined as return to dialysis, allograft nephrectomy, re-transplantation, estimated glomerular filtration rate (eGFR) <15 mL/min/1.73 m^2 or death from any cause) (Final Analysis).
    2. To evaluate the efficacy of clazakizumab in slowing/preventing the progressive loss of kidney function (as measured by eGFR using the Modification of Diet in Renal Disease 4 (MDRD4) equation) (Interim Analysis #2 (IA #2)).
    3. To evaluate the safety of clazakizumab.
    E.2.2Secondary objectives of the trial
    1. To evaluate the effects of clazakizumab on death-censored allograft loss (defined as return to dialysis, allograft nephrectomy, re-transplantation or eGFR <15 mL/min/1.73 m^2 but excluding death from any cause).
    2. To evaluate the effects of clazakizumab on albuminuria.
    3. To evaluate the effects of clazakizumab on DSA titers and mean fluorescence intensity (MFI) scores.
    4. To evaluate the effects of clazakizumab on incidence of acute rejection episodes (TCMR and ABMR).
    5. To evaluate the effects of clazakizumab on the histology of kidney biopsies according to the Banff 2015 lesion grading scores.
    6. To evaluate the effects of clazakizumab on overall patient survival.
    7. To evaluate the effects of clazakizumab on healthcare utilization due to ABMR and patient reported outcomes including health-related quality of life (HRQoL).
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Age 18-70 years.
    2. Living donor/deceased donor kidney transplant recipients ≥6 months from time of transplant.
    3. Diagnosis of CABMR (according to Banff 2015 diagnostic criteria) to include all of the following:
    • Biopsy-proven CABMR (i.e., chronic glomerulopathy (cg) >0) with/without C4d staining. Repeat biopsy to be performed if previous biopsy is not within 6 months (+3 weeks) of the start of the screening period. The local pathologist’s diagnosis will be reviewed by a central pathologist to confirm eligibility for entry into the study. Subjects without evidence of chronic tissue injury on light microscopy but who have glomerular basement membrane double contours on electron microscopy (cg1a) are eligible.
    • Positive for human leukocyte antigen (HLA) DSA (using single-antigen bead-based assays) post-transplant. Local laboratory DSA results will be reviewed by the central HLA reviewer to confirm eligibility for entry into the study. If presence of HLA DSA is confirmed within 6 months (+3 weeks) of the start of the screening period, the test does not need to be repeated for eligibility.
    • Note: Treatments for ABMR (including CABMR) or TCMR are not allowed within 3 months of the start of screening (see Exclusion Criterion 3). If a subject has received one of these treatments at any time prior, a repeat biopsy and repeat DSA test must be performed after halting / completing treatment (to show continuing CABMR). At least 2 months +- 2 weeks should elapse from the end of treatment before the repeat biopsy and DSA test can be performed.
    4. Written informed consent obtained from subject (or legally acceptable representative) before any trial-related procedures.
    E.4Principal exclusion criteria
    1. Participant is unable or unwilling to comply with study procedures in the opinion of the Investigator.
    2. Multi-organ transplant recipient or cell transplant (islet, bone marrow, stem cell) recipient. Note: recipients of multiple previous kidney transplants are allowed.
    3. Treatment for ABMR (including CABMR) or TCMR within 3 months of the start of screening.
    4. Received T cell depleting agents (e.g., alemtuzumab, anti-thymocyte globulin) within 3 months of the start of screening.
    5. Treatment with mTOR inhibitors within 4 weeks of the start of screening.
    6. Biopsy showing pure TCMR or advanced interstitial fibrosis (ci3), advanced tubular atrophy (ct3), vascular fibrous intimal thickening (cv3) or other significant causes of renal dysfunction (e.g. BK virus (BKV) nephropathy, glomerulonephritis).
    7. Impaired renal function due to disorders in the transplanted allograft (e.g., renal artery stenosis, hydronephrosis).
    8. eGFR <25 mL/min/1.73 m^2 or >65 mL/min/1.73 m^2 (MDRD4).
    9. Nephrotic range proteinuria defined as spot urine albumin creatinine ratio (UACR) ≥2,200 mg/g (≥220 mg/mmol). If spot UACR is above defined limits, repeat test on separate day to confirm ineligibility (or collect 24-hour urine to confirm nephrotic range proteinuria (≥3.0 g/day)).
    10. Pregnant, breastfeeding, or unwillingness to practice adequate contraception (i.e. a highly effective or acceptable method of contraception) during the study and for 5 months after last dose of investigational drug.
    11. History of anaphylaxis or known hypersensitivity to clazakizumab or to any constituent of the drug product.
    12. Abnormal liver function tests (LFTs) (alanine aminotransferase (ALT)/aspartate aminotransferase (AST)/bilirubin >1.5 x upper limit of normal) or other significant liver disease.
    13. History of active tuberculosis (TB).
    14. History of latent TB (e.g., positive QuantiFERON-TB test) without history of active TB unless subject has completed a full course of prophylactic treatment.
    15. History of human immunodeficiency virus (HIV) infection or positive for HIV.
    16. Seropositive for hepatitis B surface antigen (HBsAg).
    17. Hepatitis C virus (HCV) RNA positive.
    18. Known Epstein-Barr virus (EBV) mismatch (at time of transplant): donor seropositive, recipient seronegative.
    19. History of gastrointestinal perforation; diverticular disease or diverticulitis (except if disease has been fully excised); or inflammatory bowel disease (except fully excised ulcerative colitis).
    20. Neutropenia (<1,000/mm^3) or thrombocytopenia (<50,000/mm^3).
    21. Active infections requiring systemic antimicrobial agents and unresolved prior to screening.
    22. History of or current invasive fungal infection or other opportunistic infection, including (but not limited to) the following: a nontuberculous mycobacterial infection, aspergillosis, pneumocystosis, and toxoplasmosis.
    23. Active viral infections such as BKV, CMV, or EBV based on polymerase chain reaction (PCR) testing. Active infection is defined as a test result ≥ lower limit of quantification (LLOQ).
    24. Current or recent (within 3 months) participation in an interventional trial.
    25. Administration of a live vaccine within 6 weeks of the start of screening, including but not limited to the following:
    • Adenovirus
    • Measles, mumps, and rubella
    • Oral polio

    28. Presence of a condition or abnormality (i.e., clinically significant endocrine, autoimmune, metabolic, neurological, psychiatric/psychological, renal, gastrointestinal, hepatic, and hematological or any other system abnormalities that are uncontrolled with standard treatment) that in the opinion of the Investigator would compromise the safety or life expectancy of the patient or the quality of the data.
    29. History of intolerance to trimethoprim and/or sulfamethoxazole. This criterion does not apply if subject is already taking another suitable Investigator-approved alternative for Pneumocystis jiroveci pneumonia (PJP) prophylaxis, or if subject is willing to begin taking an Investigator-approved alternative prophylactic therapy at least 1 week prior to the Day 1 Baseline visit (Visit 2).
    30. Prior exposure to clazakizumab, TCZ, or other IL-6/IL-6R blockers.
    31. ABO-incompatible transplant recipient.
    32. Severe hypogammaglobulinemia (defined as immunoglobulin G (IgG) <400 mg/dL).
    33. Prior (within 2 years of the start of screening) exposure to proteasome inhibitors (e.g., bortezomib).
    34. Active infection with COVID-19.
    E.5 End points
