Study Description

Brief Summary

This phase I trial studies the side effects and best dose of SOR-C13 in treating patients with solid tumors that have spread to other places in the body (advanced) and does not respond to treatment. Drugs used in chemotherapy, such as SOR-C13, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.

Detailed Description

PRIMARY OBJECTIVES:

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.
To define the safety profiles of the treatment.

SECONDARY OBJECTIVES:

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.

Outcome Measures

Primary Outcome Measures

Incidence of adverse events and serious adverse events [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 [Up to 30 days after last dose]
Dose-limiting toxicities [Up to 28 days]
Withdrawals from the study due to treatment-related adverse events will be documented [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 [Up to 30 days after last dose]

Secondary Outcome Measures

Objective responses [Up to 6 months]
Defined as complete response(CR)s and partial response (PR).
Clinical benefit [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 [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.
