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   43845   clinical trials with a EudraCT protocol, of which   7282   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 ).

    Percentage of Participants With PD or Death as Assessed by an Independent Review Committee (IRC) [1]
    End point description
    PD was assessed by an IRC using modified Response Evaluation Criteria in Solid Tumors (RECIST). All measurable lesions up to a maximum of 5 per organ and 10 in total were identified as target lesions (TLs) and recorded at baseline. TLs should be selected on the basis of their size (those with the longest diameter) and their suitability for accurate repeated measurements either by imaging or clinically. A sum of the longest diameter for all TLs was calculated as baseline sum longest diameter (SLD). All other lesions (or sites of disease) should be identified as non-TLs and recorded at baseline. PD for TLs was defined as greater than or equal to (>/=) 20 percent (%) increase in SLD, taking as reference smallest SLD recorded since treatment started or appearance of 1 or more new lesions. PD for non-TLs was defined as appearance of 1 or more new lesions and/or unequivocal progression of existing non-TLs. Percentage of Participants with PD by IRC or death from any cause was reported.

    Percentage of Participants With PD or Death as Assessed by the Investigator
    End point description
    PD was assessed by the investigator using modified RECIST. All measurable lesions up to a maximum of 5 per organ and 10 in total were identified as TLs and recorded at baseline. A sum of the longest diameter for all TLs was calculated as baseline SLD. PD for TLs was defined as >/=20% increase in the SLD, taking as reference the smallest SLD recorded since treatment started or the appearance of 1 or more new lesions. PD for non-TLs was defined as appearance of 1 or more new lesions and/or unequivocal progression of existing non-TLs. The percentage of participants who died or experienced PD by Investigator was reported. ITT population.

    Percentage of Participants With Objective Response (OR) as Assessed by an IRC
    End point description
    Tumor response was assessed by an IRC according to modified RECIST. OR was defined as the percentage of participants with a complete response (CR) or partial response (PR). All measurable lesions up to a maximum of 5 per organ and 10 in total were identified as TLs and recorded at baseline. A sum of the longest diameter for all TLs was calculated as baseline SLD. For TLs, a CR was defined as the disappearance of all TLs and a PR was defined as >/= 30% decrease in the SLD of TLs, taking as reference the baseline SLD. For non-TLs, a CR was defined as the disappearance of all non-TLs and a PR was defined as the persistence of 1 or more non-TLs. Confirmation of response at a consecutive tumor assessment at least 4 weeks apart was required. Participants without a post-baseline tumor assessment were considered non-responders. The percentage of participants with CR or PR by IRC was reported. The 95% CI was computed using Blyth-Still Casella exact CI method. ITT population.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    19 Feb 2010
    Two interim analyses of the secondary efficacy endpoint OS were specified at the request of the Data Monitoring Committee. No interim analysis of the primary endpoint of PFS was included. The use of echocardiogram (ECHO) rather than multi-gated acquisition (MUGA) scans was recommended for the evaluation of cardiac function because of the anticipated shortage of technetium-99 (Tc99). Bone scans (skeletal X-rays) were included at the screening visit and as part of subsequent tumor assessments.
    13 May 2010
    All revisions planned for Protocol Amendment 1 were carried forward to Protocol Amendment 2, with the exception of one of the two proposed interim analyses of OS. Based on regulatory feedback, the interim analysis planned after 125 deaths, was considered to be premature and was therefore not included. The definition of PFS was updated per the United States Food and Drug Administration (US FDA) Guidance Documents regarding endpoints for oncology clinical trials to include all deaths, inclusive of deaths that occurred beyond 30 days after the last dose of study treatment.
    04 Oct 2010
    Overall survival was changed from a secondary endpoint to a co-primary endpoint to ensure more robust trial results. Further, the sample size was increased from 580 to 980 participants to ensure the study was properly powered to detect a clinically meaningful OS benefit. The number of participants in the pharmacokinetic analysis was increased from 80 to 160 participants. The frequency of the urine pregnancy test for females of childbearing potential was increased to every three cycles because of the study drugs’ potential to cause harm to a fetus. The frequency of administration of the FACT-B questionnaire was increased to obtain a more accurate assessment of the changes in symptom burden due to disease progression.
    30 May 2012
    As per Protocol Amendment 4, eligible participants randomized to the lapatinib plus capecitabine arm could cross over to receive trastuzumab emtansine if a statistically significant OS benefit in favor of trastuzumab emtansine were demonstrated.
    22 Feb 2013
    Allowed participants in both treatment arms who developed progression in the brain but demonstrated control of their systemic and visceral disease to continue to receive treatment. Included the possibility of post-trial access to trastuzumab emtansine treatment through an extension study. Updates to safety wording were made in alignment with current recommendations.
    08 Aug 2014
    The end of study definition was updated to specify that this will occur when the last participant has completed the Study Drug Completion Visit. Updates to safety wording were made in alignment with current recommendations.
