Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   42312   clinical trials with a EudraCT protocol, of which   6968   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System

    • To assess the safety and tolerability of TAS0728
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Male or females with an age ≥ 18 years.
    2. Subjects with histological- or cytological-confirmed, advanced cancer, who have progressed on (or not been able to tolerate) standard therapy or for whom no standard anticancer therapy exists. Subjects may have received two different forms of specific anti-HER2 therapy for their cancer except for breast cancer where receipt of up to four lines of anti-HER2 therapy is allowed prior to enrollment.
    a. For Phase 1, only subjects with the following molecular/genetic alterations will be enrolled:
    i. HER2+ determined by local laboratory, for example: immunohistochemistry (IHC) 3+ and/or fluorescence in situ hybridization (FISH)+ by an accurate and validated assay, or potentially actionable HER2 or HER3 mutation or amplification by next generation sequencing.
    b. For Phase 2a, subjects with one of the following tumor types will be enrolled as determined by local laboratory:
    i. Urothelial cancer with HER2 or HER3 mutation
    ii. Biliary tract cancer with HER2 or HER3 mutation
    iii. Breast cancer with HER2 or HER3 mutation
    iv. Breast cancer with HER2 amplification or overexpression as per ASCO-CAP 2013 guidelines
    v. NSCLC with HER2 or HER3 mutation
    vi. CRC with HER2 mutation or amplification
    vii. Other tumors with HER2 mutation/amplification/overexpression or HER3 mutation (gastric/GEJ, endometrial).
    c. For Phase 2a, subjects should also meet the following criteria:
    i. Radiological progression on the last line of therapy before entering this trial must be documented
    ii. At least 1 measurable lesion as defined by Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1.
    3. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
    4. Subjects must have the following laboratory values:
    a. ANC ≥ 1.5 × 109/L
    b. Hemoglobin ≥ 8.0 g/dL
    c. Platelet count ≥ 75 × 109/L
    d. Albumin ≥ 3 g/dL
    e. Serum potassium, magnesium, phosphorus, sodium, total calcium (corrected for serum albumin) or ionized calcium within institutional normal limits
    f. Aspartate aminotransferase/serum glutamic-oxaloacetic transaminase and alanine aminotransferase/serum glutamic-pyruvic transaminase ≤ 3 × upper limit of normal (ULN) or ≤ 5.0 × ULN if liver metastases are present
    g. Total serum bilirubin ≤ 1.5 × ULN
    h. Serum creatinine ≤ 1.4 × ULN or 24-hour or calculated creatinine clearance (Ccr) ≥ 50 mL/min (according to Cockcroft Gault formula).* For subjects in Phase 2a with urothelial cancer, a creatinine clearance of ≥ 40 mL/min is acceptable.
    5. Left ventricular ejection fraction (LVEF) > institutional lower limit of normal.
    *For a calculated Ccr value, the eligibility should be determined using the Cockcroft Gault formula:
    Male Ccr (mL/min) = Body weight (kg) × (140 – age)/[72 × serum creatinine (mg/dL)]
    Female Ccr (mL/min) = male Ccr × 0.85.
    6. Women of childbearing potential must have a negative pregnancy test (urine or serum) within 7 days prior to starting the study drug. Both males and females must agree to use effective birth control during the study (prior to the first dose and for 6 months after the last dose) if conception is possible during this interval. Female subjects are considered to not be of childbearing potential if they have a history of hysterectomy, or are postmenopausal defined as no menses for 12 months without an alternative medical cause. For both males and females, see Section 5.5 for definitions of contraceptive methods considered effective for this protocol.
    7. Subjects must be able to swallow and retain orally administered medication and not have any clinically significant gastrointestinal (GI) abnormalities that may alter absorption, such as malabsorption syndrome or major resection of the stomach or bowels.
    8. Able to agree to and sign informed consent and to comply with the protocol.
