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 ).

    General information about the trial
    Main objective of the trial
    To determine progression free survival (PFS) of sorafenib versus placebo after random assignment (randomized subset only).
    Protection of trial subjects
    cleary planned management of side effects e.g. treatment-associated skin toxicity, prophylactic supportive measures to prevent the development of HFSR clearly defined management of treatment-associated hypertension, of treatment-associated diarrhea, of hematological toxicities and non-hematologic toxicities
    Background therapy
    prophylactic and therapeutic supportive measures before/after development of HFSR all medication which was considered necessary for the patient's welfare and which were not expected to interfere with the evaluation of the study drug were allowed
    Evidence for comparator
    all patient received sorafenib within the first 56 days- no comparators in that initial time given There are no approved systemic treatment options for patients with metastatic uveal melanoma. Patients achieving stable disease after a 56-days run-in phase of sorafenib 400 mg bid were randomly assigned, in a 1:1 ratio, to blinded sorafenib (S) or placebo (P).

    Recruitment
    Recruitment details
    randomized placebo-controlled discontinuation study was conducted at three centers from June 2011 until December, 2016 in accordance with the standards of each site’s independent ethics committees, the Declaration of Helsinki, and GCP guidelines. In total 147 consecutive patients were enrolled in the run-in period, which was completed by 117 pat.

    Pre-assignment
    Screening details
    Chemonaïve, patients (aged ≥18 years) with metastatic uveal melanoma with at least one measurable metastasis were eligible. Additional inclusion criteria included an ECOG performance status of 0, 1 or 2, a life expectancy of at least 12 weeks, and adequate hematologic, hepatic, and renal function.

    Notes
    [1] - The number of subjects at this milestone seems inconsistent with the number of subjects in the arm. It is expected that the number of subjects will be greater than, or equal to the number that completed, minus those who left.
    Justification: that is correct: 147 patients fulfilled inclusion criteria and entered the run-in phase 30 of them dropped out during this run in phase and could not receive a restaging on day 56 evaluable patients at the end of this run-in phase at day 56: 117

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    13 Aug 2013
    the treatment allocation of patients will be unblinded if they experience progression during the randomized phase. Until 19th July 2013 31 patients have been unblinded as they experienced progression during the randomized phase. 19 of these patients had received placebo and only 12 patients had received sorafenib. As patients are randomized equally to both treatment arms (sorafenib or placebo), the suspicion arises that with regard to the primary endpoint progression-free survival after random assignment to blinded study medication treatment with sorafenib is more effective. Therefore, in order to prevent patient’s unnecessary exposure to placebo an interims analysis will be performed to verify or exclude this suspicion. Further on, due to the retirement of Prof. Dr. Max Scheulen on 1st September 2013, the coordinating investigator will change to Frau Dr. Heike Richly.
