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   43857   clinical trials with a EudraCT protocol, of which   7284   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.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To demonstrate whether tolvaptan modifies ADPKD progression as measured by changes in endpoints of total kidney volume (TKV) and
    renal function. Disease modification is evidenced further by the noninferiority of endpoint progression slope during this study for those
    receiving early, continuous treatment with tolvaptan, as compared to those with delayed treatment (ie, whose initial treatment was with
    placebo in trial 156-04-251).
    E.2.2Secondary objectives of the trial
    To determine whether, for placebo-treated subjects from trial 156-04-251, the annual rate of change (slope) in TKV and renal function changes during the crossover from placebo to tolvaptan treatment.

    To explore exposure response relationship among all subjects enrolled in this trial for changes in TKV, renal function and hypertension.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1) Successful completion (protocol defined completer without early termination) of a previous Phase 1, 2, or 3 tolvaptanADPKD or renal impairment trial, with a confirmed diagnosis of ADPKD (unless approved
    by the sponsor and medical monitor). If early
    termination from the previous trial was due to exceptional circumstances, reinitiation of tolvaptan is judged to be safe, and
    participation is approved by the sponsor and medical monitor, subjects may be enrolled beginning in January 2012.
    2) Estimated GFR ≥ 30 mL/min/1.73m2 within 45 days prior to the baseline visit (calculated using the IDMS-traceable modification of diet
    in renal disease [4 parameter MDRD] equation with correction for gender and race). Subjects with lower estimated GFR (eGFR) may be permitted with documented medical monitor approval prior to enrollment.
    E.4Principal exclusion criteria
    Trial Entry Exclusion Criteria
    1) Inability to provide written informed consent.
    2) Women of childbearing potential, or their partners, who will not adhere to the reproductive
    precautions as outlined in the Informed Consent form.
    3) Positive urine pregnancy test (women only)
    4) Subjects who are pregnant or breast-feeding.
    5) Inability to take oral medications.
    6) Subjects who have clinically significant allergic reactions to tolvaptan or chemically related structures such as benzazepines (benzazepril,
    conivaptan, fenoldopam mesylate or mirtazapine).
    7) Subjects having disorders in thirst recognition or inability to access fluids.
    8) Subjects with critical electrolyte imbalances, as determined by the investigator.
    9) Subjects with or at risk of significant hypovolemia, as determined by investigator.
    10)Subjects with clinically significant anemia, as determined by investigator.
    11)Subjects with a history of substance abuse (within the last 3 years).
    12)Subjects taking other experimental (ie, non-marketed) therapies or current participation in another clinical drug or device trial. Current
    participation in the off-drug follow up period of another ADPKD trial with tolvaptan is permitted.
    Efficacy Analysis Exclusion Criteria
    13)Subjects having contraindications to, or interferance with MRI assessments (eg, ferro-magnetic prostheses, ancurysm clips, severe
    claustrophobia).
    14)Subjects with a history of taking a vasopressin antagonist, outside of
    previous participation in a tolvaptan trial.
    15) Subjects with a history of persistant non-compliance with antihypertensive or other important medical therapy.
    16)Subjects taking medications or having concomitant illnesses likely to confound endpoint
    assessments, including taking approved (ie, marketed) therapies for the purpose of affecting PKD cysts such as tolvaptan, vasopressin
    antagonists, anti-sense RNA therapies, rapamycin, sirolimus, everolimus, or somatostatin analogs (ie, octreotide, sandostatin), and cyst reduction surgery.
    17)Subjects with advanced diabetes (ie, those with poor glycemic control evidenced by a history of severly elevated hemoglobin AIC, or
    with evidence of advanced retinpathy, nephropathy or peripheral vascular disease due to micro-or-macro vascular disease).
    E.5 End points
    E.5.1Primary end point(s)
    In subjects randomized to tolvaptan and placebo in 156-04-251 and enrolled and treated in 156-08-271 as early treated and delayed treated groups:
    • Change from the 156-04-251 baseline in TKV at Month 24 of 156-08-271
    Percent change from 156-04-251 baseline in Total kidney volume (TKV) at Month 24 in trial 156-08-271 as compared to the percent change in TKV at 156-04-251 Month 36 measured by magnetic resonance imaging (MRI)

    then

    Change in renal function (100x1/Serum Creatinine mg/dl) at Month 24 in trial 156-08-27) as compared to change in renal function at Month 36 in protocol 156-08-251, both relative to 156-04-251 end of titration baseline.

    E.5.2Secondary end point(s)
    In subjects randomized to tolvaptan and placebo in 156-04-251 and enrolled and treated in 156-08-271 as early treated and
    delayed treated groups:
    • Change from the 156-04-251 baseline in eGFR
    (Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI]) at Month 24 of 156-08-271
    • Slope of TKV of the 156-08-271 study
    • Slope of eGFR (CKD-EPI) of the 156-08-271 study
    Other Secondary Efficacy Endpoints:
    In prior placebo subjects enrolling from protocol 156-04-251:
    • Rate of change in annual TKV slope when crossing over from placebo to tolvaptan treatment
    • Rate of change in annual slope of renal function (eGFR CKD-EPI) when
    crossing over from placebo totolvaptan treatment
    For all subjects enrolled in this trial:
    • Change from baseline in TKV by exposure group
    • Change from end of titration in renal function (eGFRCKD-EPI) by exposure group
    • For subjects who are taking anti-hypertensive therapy at Baseline in this trial, percentage with clinically sustained decreases of blood
    pressure (BP) leading to a sustained reduction in anti-hypertensive therapy compared to Baseline (while taking investigational product) at
    Months 12 and 24 for hypertensive subjects.
