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   43862   clinical trials with a EudraCT protocol, of which   7285   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.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    Assess the objective response rate by RECIST guidelines of oral deforolimus in combination with trastuzumab in patients with HER2-positive metastatic breast cancer (MBC) with progression after treatment with at most 2 prior trastuzumab-based regimens.
    E.2.2Secondary objectives of the trial
    •Characterize safety and tolerability of oral deforolimus administered in combo with std dose trastuzumab
    •Evaluate the clinical-benefit response rate (CR or PR, SD ≥ six 4-wk cycles)
    •Evaluate addtn'l efficacy endpts, (e.g. duration of response, time to tumor progression, pfs, pfs rate, os).
    •Perform a series of exploratory molecular analyses such as:
    •Exploratory analysis of molecular parameters in archival tumor samples for predictive/indicative ability of mTOR inhibition impacting trastuzumab resistance (e.g. markers of tumoral PI3K/mTOR-pathway activity and related pathways). Possible analysis of the mutational/expression/activation status of specific genes (e.g. PI3CA; PTEN, p95HER2 and IGF-1R) or gene expression profiling for status of entire signaling pathways
    •Exploratory analysis of pre-/post-treatment changes in circulating tumor cells and their expression of certain HER2 and PI3K/mTOR pathway-related changes pending evolving technology
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    •Female patients, age ≥ 18 yrs
    •Histologically confirmed HER-2 positive (IHC 3+ or FISH+) metastatic breast cancer (MBC)
    •Trastuzumab-resistance, defined as disease progression on trastuzumab treatment, with at most 2 prior trastuzumab-based regimens permitted
    •Either combination or single-agent trastuzumab treatment acceptable
    •Maintenance after combination therapy considered part of that overall regimen (i.e., will be counted as one regimen)
    •Single-agent trastuzumab therapy (without disease progression) followed by combination trastuzumab therapy acceptable at the time of disease progression.
    •Adjuvant trastuzumab-containing therapy permitted and will count as one regimen
    •Measurable disease according to modified RECIST guidelines (histological/cytological confirmation of the neoplastic nature of a solitary lesion is not required in this trial)
    •ECOG performance status ≤ 1
    •Life expectancy > 3 months
    •No prior treatment with temsirolimus, everolimus, rapamycin, or any other mTOR inhibitor
    •At least 4 weeks much have elapsed between prior investigational therapy, chemotherapy or radiotherapy, and the first dose of deforolimus (≥2 weeks for signal transduction inhibitors with a half-life known to be < 24 hours, and ≥ 6 weeks for nitrosourea or mitomycin)
    •Left ventricular ejection fraction of ≥ 50%
    •Adequate cardiovascular function (e.g., ≤ class 2 New York Heart Association congestive heart failure, no myocardial infarction in the previous six months)
    •Adequate haematological, hepatic and renal function as defined below:
    •haemoglobin ≥ 9 g/dL, absolute neutrophil counts [ANC] ≥ 1.5 x 109 /L
    •platelets ≥ 100 x 109 /L
    •bilirubin ≤ ULN
    •alkaline phosphatase ≤ 2.5 x ULN
    •AST, ALT ≤ 2.5 x ULN; albumin ≥ 2.5mg/dL; creatinine ≤ 1.5 x ULN
    •Serum cholesterol ≤350 mg/dL and triglycerides ≤ 400 mg/dL
    •Patients with childbearing potential must have a negative serum pregnancy test within 7 days prior to first dose of study drug and must use an approved contraceptive method as appropriate from time of study screening until 30 days after the last dose of study drug. Non-hormonal methods must be used in this trial. Approved contraceptive methods include, for example, intra-uterine device, diaphragm with spermicide, cervical cap with spermicide or female condom with spermicide. (Spermicides alone are not an acceptable method of contraception.)
    •Availability and patient consent to obtain archival tumor tissue
    •Signed informed consent document stating that the patient understands the investigational nature of the proposed treatment
    E.4Principal exclusion criteria
    •Inadequate recovery from any prior surgical procedure or having undergone any major surgery within 2 weeks before trial entry (with the exception of minor procedures, e.g., central venous access port placement)
    •Grade 1 or Grade 2 hypersensitivity reaction to prior trastuzumab therapy if these reactions prevented further trastuzumab administration
    •Grade 3 or Grade 4 hypersensitivity reaction to prior trastuzumab
    •Patients with symptomatic intrinsic lung disease or with extensive tumor involvement of the lungs, resulting in dyspnea at rest
    •Known allergy to macrolide antibiotics
    •Pregnant or breast-feeding
    •Known history of HIV sero-positivity
    •Diagnosis of brain metastasis or leptomeningeal carcinomatosis within 3 months, and/or active brain metastases or leptomeningeal carcinomatosis, including those requiring glucocoricoid treatment

    •Active infection requiring prescribed intervention
    •Newly diagnosed (within 3 months before enrolment) or poorly controlled Type 1 or 2 diabetes
    •Newly diagnosed (within 3 months or before enrolment) or poorly controlled Type 1 or 2 diabetes
    •Other concurrent illness which, in the Investigator’s judgment, would either compromise the patient’s safety or interfere with the evaluation of the safety of the study drug
    •Concurrent treatment with medications that strongly induce or inhibit cytochrome P450 (CYP3A). Patients should be off these medications ≥ 2 weeks prior to the first dose of deforolimus. Concomitant medications that are metabolied by CYP3A are allowed (e.g., atorvastatin or simvastatin)
    •Any condition in the Investigator’s judgement that renders the patient unable to fully understand and provide informed consent and/or comply with the protocol
