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
    This phase 4, single-arm, open-label, multicenter study is designed to evaluate the efficacy and safety of brentuximab vedotin as a single agent in adult participants with histologically confirmed CD30+ relapsed or refractory classical Hodgkin Lymphoma who have not received a prior stem cell transplantation (SCT) and are considered to be not suitable for SCT or multiagent chemotherapy at the time of study entry.

    Duration of Response (DOR)
    End point description
    DOR is defined as the time in months from the date of first documentation of a CR or PR response to the date of first documentation of tumor progression or progressive disease (PD) per IRF assessment according to IWG criteria. CR is defined as the disappearance of all evidence of disease. PR is defined as regression of measurable disease and no new sites. PD is defined as any new lesion or increase by >50% of previously involved sites from nadir. ITT Population included all participants who were enrolled in the study. DOR was censored on the date of last disease assessment documenting absence of PD for those that were lost to follow-up, withdrew consent, started a new anticancer therapy other than stem cell transplantation (SCT), or discontinued treatment due to undocumented PD after last disease assessment. All responders were evaluated in this endpoint.

    An AE is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. A SAE A serious is any experience that suggests a significant hazard, contraindication, side effect or precaution that: results in death, is life-threatening, required in-patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect or is medically significant. A treatment-emergent adverse event (TEAE) is defined as an adverse event with an onset that occurs after receiving study drug. AE severity was graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.03. AEs Grade 3 and higher are severe.

    End point description
    Blood samples were collected to assess the immunogenicity of brentuximab vedotin (ATA development) using a laboratory test. Confirmed ATA-positive response was categorized as transient (defined as 1 or 2 post-Baseline confirmed ATA-positive responses) and persistent (defined as more than 2 post-Baseline confirmed ATA positive responses) and neutralizing ATA (nATA) status. The confirmed ATA-positive samples were assessed for ATA titer and delineated into having high or low titers.
