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 ).

    Overall Response Rate (ORR) [1]
    End point description
    ORR is defined as the percentage of participants achieving complete remission (CR), CR with incomplete bone marrow recovery (CRi), or partial remission (PR) as their best response per investigator assessment based on the T-PLL consensus criteria 2019. CR: All of the following response criteria must be met: Group A: -all lymph nodes < 1 cm; -spleen < 13 cm; -no constitutional symptoms; -circulating lymphocyte count < 4 × 10^9/L; -bone marrow T-PLL cells < 5% of mononuclear cells; -no other specific site involvement. Group B: -platelets ≥ 100 × 10^9 /L; -hemoglobin ≥ 11.0 g/dL; -neutrophils ≥ 1.5 × 10^9 /L. CRi: All of the CR response criteria in Group A met; at least 1 parameter in Group B not achieved unrelated to T-PLL. PR: At least 2 of the parameters in Group A and 1 parameter in Group B need to improve if previously abnormal. If only 1 parameter of both Groups A and B is abnormal prior to therapy, only 1 parameter needs to improve.

    Number of Participants With Treatment-emergent Adverse Events (TEAE)
    End point description
    An adverse event (AE) is any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. Treatment-emergent AEs are any event with onset after the first dose of study drug and no more than 30 days after the last dose of study drug. A serious AE (SAE) was an event that resulted in death, was life-threatening, resulted in hospitalization or prolongation of hospitalization, persistent or significant disability/incapacity, or an important medical event requiring medical or surgical intervention to prevent a serious outcome. The Investigator rated the severity of each AE according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE), version 5.0, where grade 1 = mild, grade 2 = moderate, grade 3 = severe, grade 4 = life-threatening and grade 5 = death. The Investigator assessed the relationship of the AE to the use of study drug.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    02 May 2019
    Removed nodular partial response (nPR) from the definition of ORR because nPR is not applicable for T-PLL. Added computed tomography (CT) scan for confirmation of response and updated the protocol so that CT scans for disease assessment were performed using a T-PLL-adapted version of the response evaluation criteria in lymphoma (RECIL) 2017 instead of using standard response evaluation criteria in solid tumors (RECIST). Updated the eligibility criteria to reduce the risk of dose interruptions or modifications, added safety guidelines for AEs associated with the underlying disease under investigation, and revised the toxicity management of ibrutinib to align with the company core data sheets dose modification guidelines.
    11 Nov 2020
    Reference to the (RECIL-based) T-PLL consensus criteria 2019 was added into the primary endpoint. Revisions were made to align the secondary objectives and endpoints. Clarified that the potential continuation of therapy is subject to local regulations and to extend the post-treatment follow-up visits period in the protocol. Updated the eligibility criteria for creatinine clearance, revised the washout period for live or attenuated vaccines, clarified that seasonal flu vaccines are allowed, and revised the contraception recommendations for male subjects. Updated the eligibility criteria to exclude subjects positive for SARS-CoV-2. Added laboratory monitoring for TLS for any increase in venetoclax dose. Updated the disease assessment criteria using the (RECIL-based) T-PLL consensus criteria and clarified that disease assessment will continue after last dose of study drug.
