• 1 other identifier: CL-CPI-613-024
• Study Type: interventional
• Target: N/A
• Locations: 1 country
• Sites: 2

Brief Summary

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.

Conditions

Metastatic Pancreatic Adenocarcinoma

Keywords

metastatic; pancreatic; adenocarcinoma; cancer

Outcome Measures

Primary Outcomes (1)

• Overall Survival (OS)

  Monitored until participants pass away, for an expected average of 6 months.

Secondary Outcomes (4)

• Changes in CA 19-9

  Monitored within 2-weeks before treatment, and every 3-cycles (months) during treatment

• Quality of Life (QOL)

  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

  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.

Study Arms (4)

CPI-613 Alone

EXPERIMENTAL

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

Any non-gemcitabine chemotherapies or best supportive care

ACTIVE COMPARATOR

This arm is for patients that have failed, or are not eligible for, all available therapies INCLUDING gemcitabine-based therapies. This arm includes any best-practice standard-of-care chemotherapies deemed appropriate by the clinical investigators, including the option for supportive care, following good clinical practice.

Drug: Any non-gemcitabine chemotherapies or best supportive care

Gemcitabine + CPI-613 in combination

EXPERIMENTAL

This arm is for patients who have failed, or are not eligible for, all available therapies EXCEPT gemcitabine-based therapies. When gemcitabine and CPI-613 are administered in combination, gemcitabine will be administered via 30-minute intravenous (IV) infusion at a concentration of 1,000 mg/m2 once-a-week on Day 1 for 3 consecutive weeks, followed by a week-of-rest. CPI-613 will be infused twice a week, administered on Days 1 and 4 for 3 consecutive weeks, followed by a week-of-rest, the same as gemcitabine. The dose of CPI-613 will be 710 mg/m2 infused IV over 2-hours (this is approximate maximum tolerated dosing \[MTD\] found from Phase I studies in combination with gemcitabine). To note, the dose of CPI-613 may be increased from 710 mg/m2 if ongoing Phase I trial data shows that the MTD of CPI-613 is higher than 710 mg/m2 CPI-613, diluted with D5W.

Drug: CPI-613; Drug: Gemcitabine

Gemcitabine alone or in combination with therapeutic agent(s)

EXPERIMENTAL

This arm is for patients who have failed, or are not eligible for, all available therapies EXCEPT gemcitabine-based therapies. Gemcitabine, or Gemcitabine-based, chemotherapy will be administered via 30-minute intravenous (IV) infusion at a concentration of 1,000 mg/m2 once-a-week on Day 1 for 3 consecutive weeks, followed by a week-of-rest. This arm includes any best-practice standard-of-care Gemcitabine-based chemotherapies deemed appropriate by the clinical investigators following good clinical practice.

Drug: Gemcitabine

Interventions

CPI-613 DRUG

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.

• 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

• 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).
