    Trial Purpose

    This is an open label, multicenter, Phase 1 study of E7046 to assess the safety and
    tolerability of E7046 and to determine the maximum tolerated dose (MTD) and/or the
    recommended Phase 2 dose (RP2D) of E7046.

    Detailed Description

    The study will be conducted in 2 parts: a dose escalation part to determine the MTD and/or
    RP2D of E7046, and a cohort expansion part with 6 to 16 participants to better characterize
    safety, efficacy, pharmacokinetics (PK), and pharmacodynamics (PD) at the RP2D. In the dose
    escalation part, increasing doses of E7046 will be administered to cohorts of 6
    participants, at dose levels ranging from 125 mg to 750 mg.

    than 3 X ULN (in absence of liver metastases) or greater than 5 X ULN (in
    presence of liver metastases) AND the participant also is known to have bone
    metastases, the liver specific alkaline phosphatase must be separated from the
    total and used to assess the liver function instead of total alkaline

    a negative beta-human chorionic gonadotropin [B-hCG] test with a minimum sensitivity
    of 25 IU/L or equivalent units of B-hCG). A separate baseline assessment is required
    if a negative screening pregnancy test was obtained more than 72 hours before the
    first dose of study drug. All females will be considered to be of childbearing
    potential unless they are postmenopausal (at least 12 months consecutive amenorrheic,
    in the appropriate age group, and without other known or suspected cause) or have
    been sterilized surgically (ie, bilateral tubal ligation, total hysterectomy, or

    childbearing potential must not have had unprotected sexual intercourse within 30
    days prior to study entry and must agree to use a highly effective method of
    contraception, from the last menstrual period prior to initiation of treatment,
    during Treatment Cycles, and for 30 days after the final dose of study treatment, and

    - Double barrier methods of contraception such as condom plus diaphragm or
    cervical/vault cap with spermicide

    - Placement of an intrauterine device

    - Established hormonal contraceptive methods: oral, injectable, or implant.
    Females who are using hormonal contraceptives must have been on a stable dose of
    the same hormonal contraceptive product for at least 4 weeks prior to dosing and
    must continue to use the same contraceptive during the study and for 30 days
    after study drug discontinuation. Female participants exempt from this
    requirement are participants who practice total abstinence or have a male
    partner who is vasectomized with confirmed azoospermia. If currently abstinent,
    the participant must agree to use a double barrier method as described above if
    they become sexually active during the Treatment Cycles, and for 30 days after
    study drug discontinuation

    20. Male participants must have had a successful vasectomy (confirmed azoospermia) or
    they and their female partners must meet the criteria above (ie, not of childbearing
    potential or practicing highly effective contraception and use a condom throughout
    the study period and for 30 days after study drug discontinuation)

    Exclusion Criteria:

    1. Other malignancy active within the previous 2 years except for basal or squamous cell
    skin cancer, superficial bladder cancer or carcinoma in situ of the cervix or breast
    that has completed curative therapy

    2. Participants with any active autoimmune disease or a documented history of autoimmune
    disease, or history of syndrome that required systemic steroids or immunosuppressive
    medications, except for participants with vitiligo or resolved childhood
    asthma/atopy. Participants with poorly controlled asthma who require intermittent use
    of bronchodilators (such as albuterol) will be excluded from this study.

    3. Participants with inflammatory bowel disease

    8. Inability to take oral medication, or malabsorption syndrome or any other
    uncontrolled gastrointestinal condition (eg, nausea, diarrhea, or vomiting) that
    might impair the bioavailability of E7046

    9. Any other major illness that, in the investigator's judgment, will substantially
    increase the risk associated with the participant's participation in this study

    10. Use of other investigational drugs within 28 days or at least 5 half-lives (whichever
    is shorter) before study drug administration
