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   43974   clinical trials with a EudraCT protocol, of which   7312   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.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Have provided written informed consent
    2. In the investigator’s judgement, is willing and able to comply with the study protocol including the planned surgical treatment
    3. Female and male patients* ≥ 18 years of age
    4. Diagnosed with histologically confirmed adenocarcinoma of the GEJ (Type I-III) or the stomach (cT2, cT3, cT4, any N category, M0), or (any T, N+, M0) that:
    a. is not infiltrating any adjacent organs or structures by CT or MRI evaluation
    b. does not involve peritoneal carcinomatosis
    c. is considered medically and technically resectable
    Note: the absence of distant metastases must be confirmed by CT or MRI of the thorax and abdomen, and, if there is clinical suspicion of osseous lesions, a bone scan. If peritoneal carcinomatosis is suspected clinically, its absence must be confirmed by laparoscopy. Diagnostic laparoscopy is mandatory in patients with T3 or T4 tumors of the diffuse type histology in the stomach.
    5. No prior cytotoxic or targeted therapy
    6. No prior partial or complete esophagogastric tumor resection
    7. ECOG ≤ 1
    8. Phase II only: Availability of a representative tumor specimen that is suitable for determination of PD-L1 and MSI status; MSI assessment will be performed locally or centrally and result must be available prior to randomization (for details, see chapter 9). PD-L1 will be assessed centrally but is not used for enrolment of the patients. The analysis requires paraffin embedded biopsy samples of the tumor.
    Phase III only: Assessment of MSI and PD-L1 [and optional TMB/EBV] must be performed locally and results for either of the following MSI-high, PD-L1 CPS≥1, TMB ≥10/MB or EBV+ must be available prior to randomization (for details, see chapter 9).
    9. Females of childbearing potential must agree to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods that result in a failure rate of <1% per year during the treatment period and for at least 5 months after the last study treatment.
    A woman is considered to be of childbearing potential if she is postmenarcheal, has not reached a postmenopausal state (has not had ≥12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus). Examples of contraceptive methods with a failure rate of < 1% per year include bilateral tubal ligation, male sterilization, hormonal implants, established, proper use of combined oral or injected hormonal contraceptives, and certain intrauterine devices. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception.
    Males must agree to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures, and agree to refrain from donating sperm, as defined below:
    a. With female partners of childbearing potential or pregnant female partners, men must remain abstinent or use a condom plus an additional contraceptive method that together result in a failure rate of 1% per year during the treatment period and for at least 3 months after the last dose of study treatment to avoid exposing the embryo. Men must refrain from donating sperm during this same period. Men with a pregnant partner must agree to remain abstinent or to use a condom for the duration of the pregnancy.
    10. Criterion integrated in criterion 9.
    11. Adequate hematological, hepatic and renal function as indicated by the following parameters:
    o Leukocytes ≥ 3.000/mm³, platelets ≥ 100.000/mm3 without transfusion, absolute neutrophil count (ANC) ≥ 1500/mm3 without granulocyte colony-stimulating factor support, Hemoglobin ≥ 90 g/L (9 g/dL) - Patients may be transfused to meet this criterion.
    o Bilirubin ≤ 1.5 x upper limit of normal, aspartate transaminase and alanine transaminase ≤ 2.5 x upper limit of normal, alkaline phosphatase ≤ 2.5 x upper limit of normal
    o Serum creatinine ≤ 1.5 x upper limit of normal, or glomerular filtration rate > 45 ml/min (calculated using the Cockcroft-Gault formula)
    o Serum albumin ≥ 25 g/L (2.5 g/dL)
    o For patients not receiving therapeutic anticoagulation: INR or aPTT ≤ 1.5 x ULN; for patients receiving therapeutic anticoagulation: stable anticoagulant regimen

    E.5 End points
    E.5.1Primary end point(s)
    Primary Endpoint Phase III: Event-free survival EFS, defined as the time from randomization to disease progression or relapse after surgery or death from any cause

    Primary Endpoint Phase II (exploratory): pCR or TRG 1a rate where pCR is defined as the absence of residual tumor based on evaluation of the resected esophagogastric specimen in the primary (as assessed by local pathology) and postoperative TNM (pTNM) stage according to the 8th version of the UICC classification (as assessed by local pathology) – both as exploratory endpoints
    E.5.1.1Timepoint(s) of evaluation of this end point
    EFS: continuously, tumor assessment every 3 months
    E.5.2Secondary end point(s)
    • Rate of pathological complete responses (pCR, TRG1a) as assessed according to the Becker criteria
    • Rate of pathological complete and subtotal remission (pCR+pSR, TRG1a/b) as assessed according to the Becker criteria
    • R0 resection rate
    • Overall survival (OS) (Phase III only)
    • OS and EFS in the subgroups of patients with PD-L1 CPS score ≥ 5 and ≥ 10 and patients with MSI (Phase III only)
    • Safety (according to NCI-CTCAE V 4.03) and tolerability
    • Perioperative morbidity and mortality rates
    • ctDNA exploratory endpoints
    E.5.2.1Timepoint(s) of evaluation of this end point
    - Rates of pathological remission: after surgery
    - R0 resection rate: after surgery
    - EFS: continuously, tumor assessment every 3 months
    - OS: continuously
    - safety and tolerability: continuously
    - Perioperative morbidity and mortality: after surgery
    - ctDNA: baseline, during treatment, before and after surgery, during follow-up

    E.8.8 Definition of the end of the trial and justification where it is not the last visit of the last subject undergoing the trial
    Database closure is defined as the end of the trial: Sites need to collect survival data of patients and are involved in the data cleaning process actively (e.g. additional source data may be requested and additonal monitoring visits may be neccessary). Therefore, database closure is considered the end of the trial.
