Study Details

Study Description

Brief Summary

This is a single-center, open-label, phase I study designed to determine the maximum tolerated dose (MTD) and safety profile of CPI-613® when used concomitantly with chemoradiation for local control of pancreatic adenocarcinoma (PDAC).

Condition or Disease	Intervention/Treatment	Phase
Pancreas Adenocarcinoma	Drug: CPI-613® (Dose level -1.0 250 mg/m^2) Drug: CPI-613® (Dose level 1.0 500 mg/m^2) Drug: CPI-613® (Dose level 2.0 1,000 mg/m^2) Drug: CPI-613® (Dose level 3.0 1,500 mg/m^2) Drug: CPI-613® Maximum Tolerated Dose (MTD) Drug: Gemcitabine Radiation: Intensity-modulated Radiation Therapy	Phase 1

Detailed Description

This study is designed to test the hypothesis that a combination of gemcitabine and radiation therapy (Gem-RT) with CPI-613®, a selective mitochondrial metabolism inhibitor in PDAC tumor cells, will be well tolerated without additional significant toxicity. Additionally, CPI-613® is expected to improve the Gem-RT effectiveness, resulting in durable local control of disease. As a necessary and initial step to translate preclinical observations into a patient setting and test our proposed hypotheses, the investigators will perform a dose-finding phase I clinical trial that has been designed to evaluate the maximum tolerated dose (MTD), recommended phase II dose (RP2D), and safety profile of CPI-613® along with standard of care Gem-RT in patients with unresectable PDAC in need of definitive local control of disease. The overarching goals for this trial are to determine the safety and toxicity of CPI-613® when given concurrently with Gem-RT.

Total bilirubin <2x the upper normal mg/dL (higher levels are acceptable if Gilbert Syndrome is suspected clinically).
Negative serum pregnancy test (if applicable).
Ability to position for radiation therapy.
Pregnancy It is not known what effects this treatment has on human pregnancy or development of the embryo or fetus. Therefore, female patients participating in this study should avoid becoming pregnant, and male patients should avoid impregnating a female partner. Non-sterilized female patients of reproductive age and male patients should use effective methods of contraception through defined periods during and after study treatment as specified below.

Female patients must meet one of the following:

Postmenopausal for at least one year before the screening visit, or
Surgically sterile, or
If they are of childbearing potential, agree to practice two effective methods of contraception from the time of signing of the informed consent form through three months after the last dose of study drug, and
Must also adhere to the guidelines of any treatment-specific pregnancy prevention program, if applicable, or
Agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, postovulation methods] and withdrawal are not acceptable contraception methods.)

Male patients, even if surgically sterilized (i.e., status postvasectomy), must agree to one of the following:

Practice effective barrier contraception during the entire study treatment period and through 90 days after the last study drug dose, or
Must also adhere to the guidelines of any treatment-specific pregnancy prevention program, if applicable, or
Agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, postovulation methods] and withdrawal are not acceptable methods of contraception.)

Ability to understand a written informed consent document, and the willingness to sign it.

Exclusion Criteria:

This exclusion is necessary because the treatment involved in this study may be significantly teratogenic.
Life expectancy less than two months.
Severe, active co-morbidity, defined as follows:

Any unresolved bowel or bile duct obstruction, or
Symptomatic myocardial ischemia, or
uncontrolled clinically significant conduction abnormalities (e.g., ventricular tachycardia on antiarrhythmics is excluded and first-degree atrioventricular (AV) block or asymptomatic left anterior fascicular block (LAFB) / right bundle branch block (RBBB) will not be excluded), or

Concurrent therapy with approved or investigational anticancer therapeutics other that what is stipulated by the protocol.
