Brief Summary

This study will be conducted to assess the safety and tolerability of E7386 in participants with solid tumor including CRC.

Detailed Description

The study will be conducted in 3 parts: dose escalation part, expansion part 1 and expansion part 2. The study will consist of Primary Assessment Phase and Continuation Phase. Primary Assessment Phase will include Pre-treatment Phase, Treatment Phase and Extension Phase (in expansion parts only).

After Treatment Phase, participants will be followed in follow-up period of Extension Phase (in expansion parts only). All participants who are still on study drug at the time of data cutoff date for the planned primary analysis will enter the Continuation phase and continue to receive E7386.

Conditions

Solid Neoplasms; Colorectal Neoplasms; Gastrointestinal Tumors

Study Design

Eligibility Criteria

Inclusion Criteria

1. Participants with a histological and/or cytological diagnosis of solid tumor must have any of the following tumor types:

1. Dose Escalation Part: Participants with advanced, unresectable, or recurrent solid tumor including CRC for which no alternative standard therapy or no effective therapy exists

2. Expansion Part 1: Participants with advanced, unresectable, or recurrent CRC in third- or later-line, Or participants with other gastrointestinal tumors such as small bowel carcinoma and gastrointestinal neuroendocrine tumors after at least 1 prior systemic chemotherapy regimen upon discussion and agreement with the sponsor

3. Expansion Part 2: Participants with advanced, unresectable, or recurrent solid tumors expected to be highly dependent on wingless/integrated (Wnt)/β-catenin signaling pathway as specified below, who have no standard therapy. Disease progression must be confirmed within the past 12 months.

• Desmoid tumor
• Solid pseudopapillary neoplasm (SPN) of pancreas
• Small bowel carcinoma with mutation of catenin beta-1 (CTNNB1) or adenomatous polyposis coli (APC)
• Adrenocortical carcinoma (ACC) with mutation of CTNNB1, APC or zinc and ring finger 3 (ZNRF3)
• Solid tumors (except for CRC) with APC mutation in participants diagnosed as familial adenomatous polyposis (FAP)
• Hepatocellular carcinoma (HCC) with CTNNB1 gain-of-function mutation
• Other types of solid tumors (except for CRC) harboring one or more Wnt-related gene mutations (example, APC, AXIN1, CTNNB1, ring finger protein 43 [RNF43], et cetera) expected to be highly dependent on Wnt/β-catenin signaling pathway based on emerging data may be enrolled upon consultation and agreement with the sponsor.

HCC participants must have:

1. A diagnosis of HCC that is histologically or cytologically confirmed (excluding fibrolamellar, sarcomatoid or mixed cholangio-HCC tumors) or clinically confirmed according to American Association for the Study of Liver Disease criteria, including cirrhosis of any etiology and/or chronic hepatitis B or C infection.

2. Barcelona Clinic Liver Cancer (BCLC) Stage C disease, or BCLC Stage B disease not amenable to locoregional therapy or refractory to locoregional therapy, and not amenable to a curative treatment approach

2. Life expectancy of >=12 weeks.

3. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0-1.

5. Adequate washout period before study drug administration:

1. Chemotherapy and radiotherapy: 3 weeks or more

2. Any therapy with antibody (Ab): 4 weeks or more

3. Any investigational drug or device: 4 weeks or more

4. Blood/platelet transfusion or Granulocyte-colony stimulating factor (G-CSF): 2 weeks or more

6. Adequate renal, bone marrow, liver function, and serum mineral level.

7. At least one measurable lesion based on RECIST 1.1.

8. Dose escalation part: Participants must consent to skin biopsies from skin tissue that is tumor-free during the study. Expansion part 1: At least 5 participants in each dose level must consent to skin biopsies from skin tissue that is tumor-free during the study. Participants may be enrolled without skin biopsies upon consultation and agreement by the sponsor. Expansion part 2: Participants must consent to skin biopsies from skin tissue that is tumor-free during the study in principle. Participants may be enrolled without consent to skin biopsies upon consultation and agreement by the sponsor.

Exclusion Criteria
