PRIMARY OBJECTIVES:
I. To define the maximum tolerated doses (MTD) of TRPV6 calcium channel inhibitor SOR-C13 (SOR-C13) in subjects with advanced solid tumor cancers of epithelial origin.
II. To define the safety profiles of the treatment.
SECONDARY OBJECTIVES:
I. To evaluate clinical response signals to the treatment. II. To assess predictive biomarkers (baseline molecular mutation status) and/or resistant pathways by comparing molecular signatures at baseline versus at time of relapse in patients who have achieved objective responses.
OUTLINE: This is a dose-escalation study.
Patients receive TRPV6 calcium channel inhibitor SOR-C13 intravenously (IV) over 2 hours on days 1, 2, 8, 9, 15, 16, 22, and 23. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Patients receive TRPV6 calcium channel inhibitor SOR-C13 IV over 2 hours on days 1, 2, 8, 9, 15, 16, 22, and 23. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Given IV
Other Name: SOR-C13 |
- Incidence of adverse events and serious adverse events [ Time Frame: Up to 30 days after last dose ]Will assess clinical symptoms and laboratory values, evaluate vital signs and perform physical exams, with a special attention to treatment- related fatigue, gastrointestinal (GI) symptoms, cardiovascular events, myelosuppression, and neurotoxicity.
- Incidence of >= grade 2 adverse events according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 [ Time Frame: Up to 30 days after last dose ]
- Dose-limiting toxicities [ Time Frame: Up to 28 days ]
- Withdrawals from the study due to treatment-related adverse events will be documented [ Time Frame: Up to 30 days after last dose ]
- Change of the treatment regimen such as dose delay and dose reduction over time by dose level due to treatment-related adverse events [ Time Frame: Up to 30 days after last dose ]
- Objective responses [ Time Frame: Up to 6 months ]Defined as complete response(CR)s and partial response (PR).
- Clinical benefit [ Time Frame: Up to 6 months ]Defined as stable disease (SD)/CR/PR according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
- Predictive biomarkers [ Time Frame: Up to 6 months ]Fisher exact test is used to associate potential biomarkers with SD >= 6 months/CR/PR. Next generation sequencing for targeted exome panel and NanoString arrays are used to reveal potential biomarkers of acquired resistance.

Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Subjects with a histologic diagnosis of solid tumor cancers of epithelial origin (metastatic epithelial ovarian, pancreatic and prostate cancers are preferred since these tumor types have TRPV6 overexpression)
