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   44334   clinical trials with a EudraCT protocol, of which   7366   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
    This is a efficacy and safety study of pembrolizumab (MK-3475, KEYTRUDA®) as monotherapy in participants with hepatocellular carcinoma (HCC) in two cohorts: participants with advanced HCC and with no curative option after disease progression on sorafenib or intolerance of sorafenib (Cohort 1) or who had not received treatment for systemic disease (Cohort 2). Study participants may receive pembrolizumab once every 3 weeks for up to 35 initial cycles (up to approximately 2 years) and a potential additional 17 cycles in a re-treatment phase (approximately an additional 1 year of treatment) . The primary objective of this study is to determine the Objective Response Rate (ORR) of pembrolizumab given as monotherapy in participants with HCC. Effective with Amendment 7: Upon study completion, participants are discontinued and may be enrolled in a pembrolizumab extension study, if available.
    Protection of trial subjects
    This study was conducted in conformance with Good Clinical Practice standards and applicable country and/or local statutes and regulations regarding ethical committee review, informed consent, and the protection of human subjects participating in biomedical research.

    An AE was defined as any untoward medical occurrence in a participant or clinical investigation participant administered a study treatment and which does not necessarily have to have a causal relationship with this treatment. An AE could be any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a study treatment, whether or not considered related to the study treatment. Any worsening (i.e., any clinically significant adverse change infrequency and/or intensity) of a preexisting condition that was temporally associated with the use of study treatment, was also an AE. Per protocol, the number of participants who experienced at least one AE was presented for first course of therapy only. The analysis population included all participants who received at least one dose of study treatment during the first course of therapy.

    		 Number of Participants Who Discontinued Study Treatment Due to an Adverse Event (AE) [9]
    End point description
    An AE was defined as any untoward medical occurrence in a participant or clinical investigation participant administered a study treatment and which does not necessarily have to have a causal relationship with this treatment. An AE could be any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a study treatment, whether or not considered related to the study treatment. Any worsening (i.e., any clinically significant adverse change infrequency and/or intensity) of a preexisting condition that was temporally associated with the use of study treatment, was also an AE. The number of participants who discontinued study treatment due to an AE was presented for first course of therapy only. The analysis population included all participants who received at least one dose of study treatment during the first course of therapy.

    All-cause mortality (ACM)=all allocated participants (n=156); AEs=all participants who received ≥1 dose of treatment. Disease progression was not considered an AE unless treatment related. Neoplasm progression (NP), malignant NP, and disease progression unrelated to treatment were excluded. The 1st and 2nd courses were reported separately.

    Cohort1:HCC-Prior Systemic Therapy with Sorafenib‌-1st Course
    Reporting group description
    		 Participants with previously systemically treated HCC received a pembrolizumab 200 mg IV infusion on Day 1 of each 3-week cycle for up to 35 administrations. Participants who stopped pembrolizumab as a result of obtaining a confirmed complete response (CR) or those who stopped after receiving 35 trial treatments were eligible for an additional 17 trial treatments (approximately an additional 1 year of treatment) after progressive disease if they met the criteria for re-treatment.

    Cohort 2: HCC-Systemic Therapy Naïve-2nd Course
    Reporting group description
    		 Participants from Cohort 2 who met the criteria for re-treatment received a pembrolizumab 200 mg IV infusion on Day 1 of each 3-week cycle for up to 17 administrations.

    Cohort 2: HCC-Systemic Therapy Naïve‌-1st Course
    Reporting group description
    		 Participants with HCC who had not received treatment for systemic disease received a pembrolizumab 200 mg IV infusion on Day 1 of each 3-week cycle for up to 35 administrations. Participants who stopped pembrolizumab as a result of obtaining a confirmed complete response (CR) or those who stopped after receiving 35 trial treatments were eligible for an additional 17 trial treatments (approximately an additional 1 year of treatment) after progressive disease if they met the criteria for re-treatment.
