Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Tumors Drug: E7046 Phase 1

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.

Official Title: An Open-Label Multicenter Phase 1 Study of E7046 in Subjects With Selected Advanced Malignancies
Actual Study Start Date : July 30, 2015

Actual Study Completion Date : February 27, 2018

Arm Intervention/treatment
Experimental: E7046
Participants with tumor types that harbor high levels of myeloid infiltrate based on the Cancer Genome Atlas (TCGA).
Drug: E7046
E7046 will be administered as a single agent orally once daily (QD) continuously in 21-day cycles. In the dose escalation part, increasing doses of E7046 ranging from 125 mg to 750 mg will be administered to cohorts of 6 participants. In the cohort expansion part, participants will be treated at the RP2D.




Primary Outcome Measures :
  1. Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) [ Time Frame: From the first dose of study drug up to 30 days after the last dose of study drug (approximately up to 2 years) ]
  2. Maximum Tolerated Dose (MTD) of E7046 [ Time Frame: Cycle 1 (21 days) ]
  3. Recommended Phase 2 Dose (RP2D) of E7046 [ Time Frame: Cycle 1 (21 days) ]
    Two RP2Ds were planned to be evaluated.


Secondary Outcome Measures :
  1. Objective Response Rate (ORR) [ Time Frame: From first dose date until disease progression/recurrence (approximately up to 2 years) ]
    The ORR is the percentage of participants achieving a best overall response of confirmed immune-related partial response (irPR) + immune-related complete response (irCR), according to immune-related Response Evaluation Criteria In Solid Tumors (irRECIST) v1.1, from first dose date until disease progression/recurrence.

  2. Progression-free Survival (PFS) [ Time Frame: From first dose date to the date of the first documentation of confirmed disease progression or death (approximately up to 2 years) ]
    PFS is defined as the time from first dose date to the date of the first documentation of confirmed disease progression or death, whichever occurs first, according to irRECIST v1.1. PFS was calculated using Kaplan-Meier product-limit method and Greenwood Formula.

  3. Duration of Response (DOR) [ Time Frame: From the date of first documented confirmed irCR/irPR until the first documentation of confirmed disease progression or death (approximately up to 2 years) ]
    The DOR is defined as the time from the date of first documented confirmed irCR/irPR, according to irRECIST v1.1 until the first documentation of confirmed disease progression or death, whichever came first.

  4. Disease Control Rate (DCR) [ Time Frame: From the first dose date until disease progression/recurrence (approximately up to 2 years) ]
    The DCR is percentage of participants achieving best overall response of confirmed irCR, irPR, or immune-related stable disease (irSD) (lasting at least 5 weeks), according to irRECIST v1.1 from the first dose date until disease progression/recurrence.

  5. Clinical Benefit Rate (CBR) [ Time Frame: From first dose date until disease progression/recurrence (approximately up to 2 years) ]
    The CBR is the percentage of participants achieving irPR + irCR + irSD (lasting at least 24 weeks), according to irRECIST v1.1 from first dose date until disease progression/recurrence.

  6. Prior definitive radiation therapy must have been completed at least 6 weeks before study drug administration and the irradiated lesions should show evidence of progression if they are intended to be considered target lesions.

    • At least 1 lesion of greater than or equal to 10 mm in the longest diameter for a non-lymph node or greater than or equal to 15 mm in the short-axis diameter for a lymph node that is serially measurable according to irRECIST using computerized tomography/magnetic resonance imaging (CT/MRI)
    • Lesions that have had definitive external beam radiotherapy or locoregional therapies such as radiofrequency (RF) ablation or brachytherapy must show evidence of progressive disease to be deemed a target lesion

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 bilateral oophorectomy, all with surgery at least 1 month before dosing). Females of 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 have a male partner who uses a condom. Highly effective contraception includes:

    • 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 90 days after study drug discontinuation)

  2. Participants with any active autoimmune disease (Appendix 2) or a documented history of autoimmune disease, poorly controlled asthma or history of syndrome that required systemic steroids or immunosuppressive medications, except for participants with vitiligo or resolved childhood asthma/atopy. Participants with asthma who require intermittent use of bronchodilators (such as albuterol) will not be excluded from this study.
  3. Participants with inflammatory bowel disease
  4. Known human immunodeficiency virus (HIV) infection
  5. Active infection requiring therapy, including known positive tests for Hepatitis B surface antigen and hepatitis C virus (HCV) RNA
  6. Major surgery within 4 weeks before the first dose of study drug
  7. Concurrent medical condition requiring the use of immunosuppressive medications, or immunosuppressive doses of systemic or absorbable topical corticosteroids except inhaled or intranasal corticosteroids (with minimal systemic absorption)
  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
