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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    General information about the trial
    Main objective of the trial
    PHASE I Determine Maximum tolerated dose (MTD) of niraparib plus cabozantinib combination in patients with advanced urothelial cancer or renal cell carcinoma. PHASE II Evaluate the efficacy of niraparib plus cabozantinib combination in patients with advanced urothelial cancer (6 months PFS).
    Protection of trial subjects
    The patient signed the informed consent before carrying out any procedure related to the study. Physical examination, vital signs, 12-lead ECG, hematology, biochemistry, urinalysis, pregnancy test if applicable and tumor evaluation were made before to start study treatment and during their participation in the study, according to the protocol.

    Dose limiting toxicity [1]
    End point description
    The following toxicities were considered DLTs: 1) Febrile neutropenia or grade 4 neutropenia without fever for >5 days. 2) Grade 4 thrombocytopenia or anemia. 3) Grade 3 non-hematologic toxicity except for nausea, vomiting, diarrhea or electrolyte abnormality corrected within 48 hours, or elevated creatinine corrected within 24 hours. 4) Any related ≥ Grade 3 AE which is unexpected in severity and/or duration compared to the known safety profiles of cabozantinib and niraparib when used as single agents, and that cannot be managed by dose modification (reduction or interruption) and adequate supportive care, and requires permanent discontinuation of cabozantinib and/or niraparib. 5) The inability to take ≥ 75% of the total planned cabozantinib or niraparib dose during DLT evaluation period.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    23 Jan 2020
    Niraparib IB has been updated to a new version, frequency of adverse events has changed and new version of SAE notification form has been added as annex in the protocol. Exclusion criteria number 4 will be applicable only to patients included in phase II in which main objective is to evaluate the effectiveness of the combination. It has been detailed that if one of the study agents need to be interrupted due to toxicity, patient can continue only with the other agent. Furthermore, frequency of stool samples collecting for molecular studies has been modified, stool sample at end of study or progression disease is replaced by day 1 from cycle 4. Minor additional changes have been implemented in the protocol. Protocol and PIS have been updated accordingly with mentioned changes.
    05 Nov 2020
    In the analysis of the second cohort of patients included in the study (DL2: niraparib 200 mg/day and cabozantinib 20 mg/day), adverse events have been documented that would correspond to dose-limiting toxicities (DLTs) as defined in the protocol. However, at the investigators' meeting on 21 September, individual cases were reviewed and it was determined that some of the reported adverse events that would be considered TLDs could be justified by reasons unrelated to the study medication. On the other hand, the remaining patients included in the study, both at dose level 1 (DL1: niraparib 100 mg/day and cabozantinib 20 mg/day) and dose level 2 (DL2) showed mostly excellent tolerability to treatment with minimal toxicities reported, so it was considered preparing this protocol amendment to include three additional patients at dose level DL2 to assess with a larger number of patients whether the dose level is safe for use in phase II. In the event that the three new patients included in DL2 do not report any DLT, this dose level would be used in phase II of the study. If a new dose-limiting toxicity grade 3-4 as specified in the study protocol is reported in the 3 additional level 2 patients, it is propose to explore a new dose level not established in the initial protocol, but due to the characteristics of each drug and toxicity/efficacy profiles we understand that it would be feasible in this scenario of patients with advanced disease progressed to previous therapeutic lines. In the new cohort called DL1.1, a dose of 100 mg/day of niraparib and 40 mg/day of cabozantinib is set to investigate a dose that is safe and optimises the potential benefit that patients could derive from this combination.
