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   44359   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 ).

    General information about the trial
    Main objective of the trial
    To assess confirmed response rate by RECIST 1.1 of crizotinib and fulvestrant in the breast cohort To assess confirmed response rate by RECIST 1.1 of crizotinib monotherapy in the diffuse gastric cancer, triple negative lobular breast cancer or CDH1-mutated solid tumour (basket) cohort
    Protection of trial subjects
    The trial was reviewed by an independent group of people called a Research Ethics Committee to protect the safety, rights, wellbeing and dignity of participants. It received The study favourable opinion by the London – Fulham Research Ethics Committee, confirming the trial met the required ethical standards. In addition, the Medicines and Healthcare products Regulatory Agency (MHRA) approved the use of crizotinib for this study. All participants provided full informed consent prior to any trial procedures. The eligibility criteria ensured that only patients who were fit for treatment and fully informed could take part. Participant safety monitoring was conducted throughout the trial, including regular hospital visits with clinical examinations to confirm participants remained well enough for continued treatment. All treatment and care of patients during the trial was provided by appropriately trained and delegated staff. Adverse events were collected and monitored continuously to ensure timely identification and management of any safety concerns. The trial was overseen by an Independent Data Monitoring Committee, a Trial Management Group, a Trial Steering Committee, and a Safety Review Committee. These groups met regularly throughout the conduct of the trial to review safety data and ensure participants were protected at all times during the study.

    PFS is defined as the time from baseline treatment to the first occurrence of PD, as determined by the investigator using RECIST v1.1, or death from any cause during the study, whichever occurs first. PD is defined as greater than or equal to (>/=) 20 percent (%) relative increase and >/=5 millimeter (mm) of absolute increase in the sum of diameters (SD) of target lesions (TLs), taking as reference the smallest SD recorded since treatment started, or appearance of 1 or more new lesions.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    18 Jan 2019
    Addition of overall survival (OS) as a secondary endpoint. Addition of CA125 testing for lobular breast patients added into the amended protocol (in text and schedule of events table) as it is frequently a more useful tumour marker than CA15-3 for patients with peritoneal disease. Removal of prior fulvestrant as an exclusion criterion. The Schedule of Events table amended to include: • An extra CA125 test (for Breast patients). • A “Survival follow-up (every 6 months)” column and row.
    01 Oct 2020
    Renaming of the gastric cancer cohort to a basket cohort that also includes triple negative lobular breast cancer or CDH1-mutated solid tumour patients. Addition of inclusion criterion for E-cadherin negative patients in both the breast and basket cohorts. Amendment to pregnancy prevention guidance following update to SmPC for fulvestrant IMP.
    17 Feb 2022
    Following meetings of the Independent Data Monitoring Committee and Trial Steering Committee, it was recommended to open up the inclusion criteria to improve recruitment by including a CDK4/6 inhibitor as a previous line of therapy for lobular breast cancer patients instead of only a line of chemotherapy. Other substantial changes made for reporting of adverse events for abnormal laboratory values, off-site procedures being allowed due to emergency situations such as COVID-19 and instructions added for the management of non haematological toxicities
    20 Feb 2023
    Amendment to patient information sheet and study RSI following updated SmPC for Crizotinib.
