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   44358   clinical trials with a EudraCT protocol, of which   7384   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
    - Part A and Part B (ANV419 single agent dose escalation using single patient cohorts and AN419 single agent dose escalation by 3+3 design, respectively): To evaluate the safety and tolerability of ANV419, and to determine the maximum tolerated dose (MTD) and the recommended Phase 2 dose (RP2D) of ANV419 - Part C (ANV419 single agent dose intensification in non-small cell lung cancer [NSCLC]): To evaluate safety and tolerability of ANV419 administered with initial dose intensification - Part D (ANV419 dose escalation in combination with ipilimumab): To evaluate safety and tolerability, MTD and RP2D of ANV419 in combination with ipilimumab
    Protection of trial subjects
    In addition of frequent safety parameters collection, functional status and well-being in the study were evaluated by the EQ-5D-5L patient-reported outcome (PRO) and the EORTC QLQ-C30.

    Part A and B: The starting dose of ANV419 was 3 μg/kg body weight. The dose was increased based on the CRC decision upon review of the safety data. The doses ranged from 3 to 24 μg/kg Q2W in Part A and from 24 to 364 μg/kg Q2W and 243 μg/kg Q3W in Part B. Part C: The dose of ANV419 was 162 µg/kg given Q1W for 4 weeks, followed by 243 µg/kg Q2W. Part D: The starting dose of ANV419 in combination with ipilimumab (Part D) was 72 μg/kg given Q3W in combination with ipilimumab 1 mg/kg on Day 1 of every cycle.
