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   43871   clinical trials with a EudraCT protocol, of which   7290   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.

    General information about the trial
    Main objective of the trial
    Primary safety objective is to evaluate the safety and tolerability of CCX140-B, based on subject incidence of adverse events over 52 weeks of treatment, in subjects with diabetic nephropathy (DN). Primary efficacy objective is to evaluate the efficacy of CCX140-B, compared to placebo, over 52 weeks of placebo-controlled treatment based on changes from baseline in first morning urinary albumin:creatinine ratio (UACR).
    Protection of trial subjects
    The study was conducted in accordance with the Declaration of Helsinki and with all applicable laws and regulations of the locale and country where the study was conducted, and in compliance with Good Clinical Practice Guidelines. Only subjects that met all the study inclusion and none of the exclusion criteria were entered in the study. The rationale of the study, procedural details, and investigational goals were explained to each subject, along with potential risks and benefits. Each subject was assured of his/her right to withdraw from the study at any time.

    Recruitment
    Recruitment details
    883 subjects were screened, 332 (37.6%) were randomized, and 551 (62.4%) subjects failed screening. The randomisation was stratified according to the baseline degree of albuminuria and the baseline eGFR.

    Pre-assignment
    Screening details
    The Screening Period was up to 21 days and included 2 study visits. Eligible subjects visited the study center on Day 1, after an overnight fast of at least 10 hours, for a physical examination, vital signs measurements, laboratory tests, stratification, and randomization.

    1. The study medication kit, bottle, and capsule appearances were identical 2. Limited access to the randomization code: study site personnel, study subjects, personnel responsible for study monitoring, and biostatisticians and data managers 3. Unblinded CCX140 plasma concentration results were not shared with study sites throughout the study 4. Efficacy data were not made available to study team members outlined in (2) unless it was for safety monitoring

Variance-covariance matrix assumed to be unstructured. Treatment group difference at Week 52 estimated with the simple contrast and the overall between-group difference over the course of the study. Ho: Neither CCX group differs from placebo Ha: At least one of the CCX140-B groups differs from placebo.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    05 Apr 2012
    The lower limit of the UACR eligibility criterion was changed from 200 mg/g creatinine to 100 mg/g creatinine and the lowest UACR stratum subject enrollment limit was changed from not more than 25% to not more than 40% of subjects enrolled. Rationale: To increase the number of subjects to be recruited in the lowest UACR stratum because this stratum was not well represented in the study population. Subjects who previously were found ineligible during screening because of urinary UACR 100 to 199 mg/g creatinine were allowed to be re-screened for the study.

    The following changes to the study conduct were made and the protocol was amended accordingly: 1. The Treatment Period was extended from 12 weeks to 52 weeks. Rationale: To evaluate the longer term safety and efficacy profile of CCX140-B in subjects with DN; 2. The Follow-up Period was changed from starting at the end of the 12-week period to starting at the end of the 52 week period. Rationale: To facilitate uninterrupted dosing from the end of 12 weeks through 52 weeks; 3. The protocol was revised to provide information on the study procedures required at each study visit; 4. As an option contemplated when the clinical study was designed, the sample size of the study was increased from 135 to up to 270 subjects. Rationale: To provide an adequate number of subjects for the study extension and to increase the statistical power of the study to detect a treatment effect on albuminuria, the primary efficacy parameter of the study, and on other efficacy parameters; 5. Potential reasons for early withdrawal from the study were revised. Rationale: To reflect the study extension; 6. New preclinical results from recently completed studies, including long-term rat and dog toxicology studies, were added; 7. New clinical data from recently completed clinical trials were added; 8. Provision was made for a formal interim analysis of efficacy and safety data when at least the first 135 subjects enrolled had completed at least their Day 85 Visit. Rationale: To plan for future clinical trials; and 9. The exploratory markers (PAI-1 and NT-proBNP) were added. Rationale: To evaluate the effect of CCX140-B on cardiovascular markers.

    The following changes to the study conduct were made and the protocol was amended accordingly: 1. Two additional urine and serum samples were collected on 2 days after the Day 365 Visit. Rationale: To reduce variability by having triplicate measurements instead of single measurements for the key efficacy parameters, particularly UACR and eGFR. 2. Changes to the protocol were made as 332 subjects had finally be enrolled in the study; 3. The Day 365 allowable visit window was changed from plus or minus 4 days of the scheduled Day 365 Visit to within 4 days prior to the scheduled Day 365 Visit. Rationale: In order to collect the 2 additional urine and serum samples after the Day 365 Visit as close as possible to the end of the study medication treatment period; and 4. Language was added to indicate that a CDF would be calculated for the percent change from baseline in eGFR.

    Interruptions (globally)

    Were there any global interruptions to the trial? No

    Limitations and caveats

    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    The efficacy analysis was made on the subset of the ITT population whose treatment was not interrupted between day 85 and day 113 as it was the most relevant population from an efficacy evaluation perspective.
