Enzalutamide in Combination With Gemcitabine and Nab-Paclitaxel for the Treatment of Advanced Pancreatic Cancer
Study Details
Study Description
Brief Summary
The main purpose of this study is to find out the dose of enzalutamide that can be safely given with gemcitabine and nab-paclitaxel in patients with advanced pancreatic cancer. Researchers also want to find out the side effects of these drugs when given together. This study will help in finding out the effect on tumor of the combination of enzalutamide, gemcitabine and nab-paclitaxel. In the first part of the study, different doses of enzalutamide will be tested. In the second part of the study, all patients will be started at the same dose of enzalutamide.

| Experimental: Dose Escalation and Dose Expansion Dose Escalation: To find the dose of enzalutamide that can be safely given with gemcitabine and nab-paclitaxel in patients with advanced pancreatic cancer. Dose Expansion: To find the effect on tumor of the combination of enzalutamide, gemcitabine and nab-paclitaxel. |
Drug: Enzalutamide
The starting dose of enzalutamide will be 80 mg (Level 1) daily, taken orally. The dose escalation schedule is a standard 3 + 3 design. In the first part of the study, different doses of enzalutamide will be tested. In the second part of the study, all patients will be started at the same dose of enzalutamide.
Other Names:
Drug: Gemcitabine
The starting dose of gemcitabine will be 1000 mg/m^2 administered intravenously on days 1, 8 and 15 of each cycle.
Other Names:
Drug: Nab-paclitaxel
The starting dose of nab-paclitaxel will be 125 mg/m^2 administered intravenously on days 1, 8 and 15 of each cycle.

Outcome Measures
Primary Outcome Measures
- Maximum Tolerated Dose (MTD) [Up to 18 months]
To determine the maximally tolerated dose (MTD) of enzalutamide in combination with gemcitabine and nab-paclitaxel in advanced pancreatic cancer.
Eligibility Criteria
Criteria
Inclusion Criteria:
-

Eastern Cooperative Oncology Group (ECOG) performance status <2 (Karnofsky >60%)
-
Life expectancy of greater than 3 months
-
Must have normal organ and marrow function
-
Prior treatment with gemcitabine alone or 5-Fluorouracil with radiation as an adjuvant therapy will be allowed; Should not have received gemcitabine within 6 months of starting the study treatment; 5-Fluorouracil or radiation treatment should be received more than 4 weeks prior to receiving the study drug.
-
Women of child-bearing potential and men must agree to use adequate contraception prior to study entry and for the duration of study participation. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of the study treatment.
-
Ability to understand and the willingness to sign a written informed consent document
Exclusion Criteria:
-
Prior treatment with any cytotoxic chemotherapy except as an adjuvant therapy. Participant should not have received gemcitabine within 6 months of starting the study treatment. 5-Fluorouracil or radiation treatment should be received more than 4 weeks prior to receiving the study drug.
-
May not be receiving any other investigational agents within 4 weeks of starting the study treatment and during the study period.
-

-
History of allergic reactions attributed to compounds of similar chemical or biologic composition to gemcitabine, nab-paclitaxel or enzalutamide.
-
Have undergone major surgery within 4 weeks prior to starting the study treatment.
-
Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements; history of myocardial infarction within 6 months of starting study treatment.

-
Any significant medical condition, laboratory abnormality, or psychiatric illness, that would prevent participating in the study, including the inability to swallow capsules
-
Any active infection not controlled by antibiotics
-
Concomitant medications that lower seizure threshold
