Safety and Effectiveness Study of CPI-613 and/or Gemcitabine to Treat Metastatic Pancreatic Cancer

A Phase II Open-Label Clinical Trial of CPI-613 Given Alone, or in Combination With Gemcitabine, in Patients With Metastatic Pancreatic Cancer

This Phase II study is conducted to assess the safety and efficacy of CPI-613 in patients with metastatic pancreatic cancer. The primary outcome measure is Overall Survival (OS). The secondary outcome measures are: changes in CA 19-9, Quality of Life (QOL), Progression-Free Survival (PFS), and safety.

• Any active uncontrolled bleeding or patients with a bleeding diathesis (e.g., active peptic ulcer disease)
• Patients with active central nervous system (CNS) or epidural tumor
• Lactating females (Note: Lactating females are excluded because the effects of CPI-613 on a nursing child are unknown)
• Life expectancy less than 2 months
• Unwilling or unable to follow protocol requirements
• Dyspnea with minimal to moderate exertion, or patients with pleural, pericardial, or peritoneal effusions
• Active heart disease including but not limited to symptomatic congestive heart failure, symptomatic coronary artery disease, symptomatic angina pectoris, symptomatic myocardial infarction, arrhythmias requiring medication, or symptomatic congestive heart failure. Also patients with a history of myocardial infarction that is <1 year prior to registration, or patients with previous congestive heart failure (<1 year prior to registration) requiring pharmacologic support or with Left Ventricular Ejection Fraction <50%).
• A marked baseline prolongation of QT/QTc interval (e.g., repeated exhibition of a QTc interval >470 ms.); a history of additional risk factors for torsade de pointes (e.g., heart failure, hypokalemia, family history of Long QT Syndrome).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: CPI-613 Alone; This arm is for patients that have failed, or are not eligible for, all available therapies INCLUDING gemcitabine-based therapies. CPI-613 drug product, provided in concentrated form at 50 mg/mL, must be diluted with D5W prior to administration. CPI-613 is to be infused intravenously (IV) via a central venous catheter. CPI-613 will be given 2x weekly, administered on Days 1 and 4 of each of the 3 treatment weeks, followed by a week of rest. The dose of CPI-613 will be 3,000 mg/m2 infused IV over 2 hours (this is approximate maximum tolerated dosing [MTD]), via a central venous catheter with D5W running at a rate of about 125-150 mL/hr.	Drug: CPI-613; CPI-613 drug product, provided in concentrated form at 50 mg/mL, must be diluted with D5W prior to administration. CPI-613 is to be infused intravenously (IV) via a central venous catheter. CPI-613 will be given 2x weekly, administered on Days 1 and 4 of each of the 3 treatment weeks, followed by a week of rest.

Drug: Any non-gemcitabine chemotherapies or best supportive care
Experimental: Gemcitabine + CPI-613 in combination; This arm is for patients who have failed, or are not eligible for, all available therapies EXCEPT gemcitabine-based therapies.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
Overall Survival (OS)	Monitored until participants pass away, for an expected average of 6 months.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Changes in CA 19-9	CA 19-9 is monitored through blood work ≤2 weeks before treatment and after every third cycle (12 weeks) of treatment while on-study. CA 19-9 is a pancreatic tumor biomarker and a decline in CA 19-9 during and after therapy may be a marker of treatment efficacy.	Monitored within 2-weeks before treatment, and every 3-cycles (months) during treatment
Quality of Life (QOL)	QOL will be assessed as described by Aaronson NK, et al. 1993. It assesses how the various treatments and the disease affect the daily living abilities of the patient.	Monitored before, during, and 1-week after treatment with CPI-613, for an expected average of 20 weeks.
Progression-Free Survival (PFS)		Monitored during treatment with CPI-613 and until participants passed away, which will be an expected average of 6 months.
Safety	Safety assessment will be based on clinical signs, vital signs, blood work, adverse events (AEs), serious adverse events (SAEs), etc.	Monitored just before study treatment, and during study treatment at the end of every 4-week treatment cycle, for an expected average of 20 weeks.
