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   43865   clinical trials with a EudraCT protocol, of which   7286   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 ).

    General information about the trial
    Main objective of the trial
    To evaluate the potential for denosumab to treat hypercalcemia of malignancy that does not respond to recent treatment with Intravenous (IV) bisphosphonates by lowering corrected serum calcium (CSC) ≤ 11.5 mg/dL (2.9 mmol/L) by study day 10.
    Protection of trial subjects
    This study was conducted in accordance with the current version of the Declaration of Helsinki and the FDA and International Conference on Harmonisation (ICH) Good Clinical Practice (GCP) regulations. The study protocol, subject information, and informed consent form were reviewed and approved by the independent ethics committee (IEC) or institutional review board (IRB) for each study center. All subjects provided written informed consent after the aims, methods, and potential hazards of the study were adequately explained; the appropriate informed consent was obtained before any protocol-specific screening procedures or any investigational products were administered.

    End point description
    Response is defined as corrected serum calcium (CSC) ≤ 11.5 mg/dL, within 10 days after the first dose of denosumab. For all CSC values, if albumin was < 4 g/dL, the following formula was used to calculate CSC: CSC = Total serum calcium [mg/dL] + (0.8 x (4 – serum albumin [g/dL])). The Response Analysis Subset included all participants who received at least 1 dose of denosumab and had a screening CSC (from local lab) > 12.5 mg/dL (3.1 mmol/L).

Participants were censored on the last CSC assessment day if their CSC level never reached > 11.5 mg/dL after the first response. If a participant had no CSC assessment after the first response, duration of response was set to zero and censored.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    14 May 2010
    The primary reason for this amendment was to delete the exclusion of a prior history or current evidence of ONJ, and related factors. Subjects who qualified for this protocol, ie, HCM that is relapsed or refractory to bisphosphonate treatment, could have been previously treated with long-term bisphosphonates for their underlying malignancy, which has been shown to be associated with ONJ. HCM is a serious and potentially life-threatening condition that requires immediate treatment. Excluding bisphosphonate-refractory subjects with prior or current ONJ or related factors would deny them treatment with another anti-resorptive agent that could potentially reduce their serum calcium levels. Additional changes included the following: -deleted the exclusion criterion of previous treatment with denosumab -modified the contraceptive exclusion criteria -clarified that screening chemistry and pregnancy testing was to be performed at a local laboratory -changed the criteria for denosumab discontinuation, such that after 4 doses of denosumab or by study day 57, denosumab could be discontinued if CSC ≥ 12.5 mg/dL instead of ≥ 11.6 mg/dL -modified the informed consent to be consistent with the protocol and updated safety information -made minor wording changes and clarifications
    05 May 2011
    -Modified the eligibility criteria and informed consent to include 2 methods of highly effective contraception during treatment and for 7 months after the last dose of denosumab -Modified the prestudy window for treatment with other therapeutic agents for hypercalcemia such that the determination for evaluating the expected potentially effective therapeutic window of these agents was at the discretion of the physician -Made minor revisions to definitions of subsets, objectives, and endpoints
