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   43870   clinical trials with a EudraCT protocol, of which   7289   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
    (Ph I) To determine the maximum tolerated dose/recommended phase two dose (MTD/RP2D) and the associated dose-limiting toxicities (DLTs) observed during the first cycle of treatment with romidepsin in combination with danusertib in patients with relapsed or refractory Hodgkin and Non-Hodgkin Lymphoma. (Ph II - NOT PERFORMED) To evaluate antitumor activity of romidepsin in combination with danusertib in patients with relapsed or refractory Peripheral T-Cell Lymphomas who have received at least one prior systemic therapy.
    Protection of trial subjects
    This study was in compliance with the ethical principles derived from the Declaration of Helsinki and the International Conference on Harmonization (ICH) Good Clinical Practice (GCP) guidelines. All the local regulatory requirements pertinent to safety of trial subjects were also followed during the conduct of the trial. Each subject, or the subject's representative, signed an informed consent form prior to screening. In the dose-escalation phase, patients were allocated to cohorts of 3 to 6 patients receiving a fixed dose of romidepsin combined with different doses of danusertib. The first two patients in each cohort should have been treated with at least 2 weeks of delay between the first and the second patient. In absence of 1st cycle DLT in the first patient, the third patient could be enrolled at any time.

    Recruitment
    Recruitment details
    Between 11 December 2013 and 04 February 2016, 12 patients with relapsed or refractory Hodgkin and Non Hodgkin lymphoma, in the absence or unable or who refused to undergo alternative salvage regimens of proven efficacy, were enrolled in the Phase I part of the study. Two Italian centers conducted the study.

    Pre-assignment
    Screening details
    In the Phase I of the study both Hodgkin and non-Hodgkin lymphomas were included, while in the Phase II only patients with Peripheral T-cell lymphomas should have been enrolled. However, the study was closed on 15 December 2016 at the end of the Phase I part for Sponsor decision.

    Danusertib was administered as 3-hr IV infusion on Days 1 and 8 q4wks. The starting dose of danusertib was 200 mg/m2 (corresponding to a cumulative dose of 400 mg/m2 in a 4-week cycle). The proposed starting dose was chosen based on the tolerability seen in the ongoing and completed clinical trials with similar or higher total doses.

    Dosage and administration details Danusertib was administered as 3-hr IV infusion on Days 1 and 8 q4wks. The starting dose was 200 mg/m2 and it was expected that at least two different doses of danusertib (i.e., 200 mg/m2, 300 mg/m2) would have been tested, but due to dose limiting toxicities in 2/6 patients treated at the first dose level of danusertib (200 mg/m2) with romidepsin (12 mg/m2) the following 6 patients were treated at 160 mg/m2 of danusertib plus romidepsin at 12 mg/m2. No DLTs occurred among the 6 patients of the dose level -1 who completed the first cycle of treatment.

    Notes
    [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point.
    Justification: Descriptive analyses. In the dose-escalation phase, pts were allocated to cohorts of 3 to 6 pts, as follows: If 0/3 pts experienced 1st cycle DLT, the next cohort would start one dose level higher; If 1/3 pts experienced 1st cycle DLT, up to 3 more pts would start at the same dose level; If 1/6 experienced 1st cycle DLT, the next cohort would start one dose level higher. If ≥ 2/3 or ≥ 2/6 pts experienced DLTs in the 1st cycle, the then the MTD have been considered to be exceeded.
