Clinical Trial Summary

This pilot clinical trial studies 6,8-bis(benzylthio)octanoic acid in treating patients with locally advanced or metastatic pancreatic cancer. Drugs used in chemotherapy, such as 6,8-bis(benzylthio)octanoic acid, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.

Description:

PRIMARY OBJECTIVES:

I. To determine initial estimates of overall survival (OS).

SECONDARY OBJECTIVES:

I. To determine response rate. II. To determine progression free survival (PFS).

OUTLINE:

Patients receive 6,8-bis(benzylthio)octanoic acid intravenously (IV) over 2 hours on days 1-5 of week 1 (pre-course 1 only), days 1 and 4 of weeks 2 and 3 (course 1 only), and days 1 and 4 of weeks 1-3 (courses 2-6). Treatment repeats every 4 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity.

Eligibility

Inclusion Criteria:

• Histologically and cytologically proven locally advanced or metastatic pancreatic adenocarcinoma that is not amenable to surgery, radiation, or combined modality therapy with curative intent, and has failed or is not eligible for available chemotherapies

• Local, locally-advanced, or metastatic disease documented as having shown progression on a scan (e.g., computed tomography [CT], magnetic resonance imaging [MRI])

• Measurable tumor according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria with at least one unidimensionally measurable target lesion

• No evidence of biliary duct obstruction, unless obstruction is controlled by local treatment or, in whom the biliary tree can be decompressed by endoscopic or percutaneous stenting with subsequent reduction in bilirubin to below 1.5 x upper level of normal (ULN)

• Mentally competent, ability to understand and willingness to sign the informed consent form

Exclusion Criteria:

• Patients receiving any other standard or investigational treatment for their cancer, or any other investigational agent for any indication within the past two weeks prior to initiation of CPI-613 (6,8-bis(benzylthio)octanoic acid) treatment

• Serious medical illness that would potentially increase patients' risk for toxicity

• Any active uncontrolled bleeding and any patients with a bleeding diathesis (e.g., active peptic ulcer disease)

• Pregnant women, or women of child-bearing potential not using reliable means of contraception

• Lactating females

• Fertile men unwilling to practice contraceptive methods during the study period

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Overall Survival	Survival curves for OS will be estimated using Kaplan-Meier techniques.	From the first dose of 6,8-bis(benzylthio)octanoic acid to death, assessed up to 3 years
Secondary	Response rate	The proportion of patients who are complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD) will be presented. The proportion of responders will be estimated as the percent of patients who are CR or PR. A 95% confidence interval will be included.	Up to 3 years
Secondary	Progression Free Survival	Survival curves for PFS will be estimated using Kaplan-Meier techniques.	From the first dose of 6,8-bis(benzylthio)octanoic acid to disease progression (DP) or death due to any cause, assessed up to 3 years
Secondary	Safety profile assessed using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0		Up to 3 years
