Intervention model description: 2 parallel arm phase II study of galeterone alone or galeterone with gemcitabine in advanced pancreatic cancer
Primary purpose: TREATMENT

Brief summary: Assess the effectiveness of galeterone in advanced pancreatic adenocarcinoma

Detailed description: This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of galeterone, an investigational drug, in pancreatic cancer.

The FDA (the U.S. Food and Drug Administration) has not approved galeterone for pancreatic cancer. Galeterone is an androgen receptor inhibitor that showed anti-cancer activity in pancreatic cancer in research lab. In this study, the investigator is interested in evaluating galeterone alone or in combination with chemotherapy in treating pancreatic cancer.

Eligibility criteria: Inclusion Criteria:

2. Agree to comply with the study requirements and agrees to come to the clinic/hospital for required study visits
3. 18 years of age or order
4. Histologic or cytologic diagnosis of pancreatic adenocarcinoma
5. Measurable metastatic disease documented by CT/MRI at least 1cm in greatest dimension
6. Have received 2 lines of prior systemic therapy; those patients must demonstrate continued disease progression (RECIST 1.1) and must not have received chemotherapy for at least 4 weeks prior to trial assignment;
7. ECOG performance status must be 0-2 (Appendix A).
8. All participants (male and female) with reproductive potential must practice an effective method of contraception while on this study in order to minimize risks to fetuses.
9. Men and women of all ethnic groups are eligible for this trial.
10. Able to swallow up to six pills and retain oral medication
11. Expected life expectancy of more than 12 weeks.
12. Patient has adequate bone marrow function as demonstrated by the following blood

    * counts at Baseline (obtained ≤14 days prior to randomization):
    * Absolute neutrophil count (ANC) ≥1.5 × 109/L;

   * History of adrenal insufficiency or hyperaldosteronism.
   * Gastrointestinal disorders or gastric bypass surgery, with the exception of pancreatic cancer and its complications, including lap bands that could interfere with the absorption of galeterone.
   * Serious active infections requiring systemic treatment or nonmalignant medical illnesses that are uncontrolled.
   * History of seizure or any condition or concomitant use of any medication that may predispose to seizure or lower the seizure threshold.
   * History of loss of consciousness or transient ischemic attack within 12 months of randomization.
   * History of (in the past 5 years) other malignancy, other than curatively treated nonmelanomatous skin cancer and superficial transitional cell carcinoma of the bladder.
   * Cranial/spinal epidural disease.
   * The patient has known allergy to any of the treatment components.
6. Any physical or mental condition or social situation that, in the opinion of the Investigator, may interfere with the patient's ability to comply with the trial procedures, confound the ability to interpret data from the study or places the patient at unacceptable risk if he participates in this study.
7. Current alcohol abuse or illicit drug use.
8. Since the teratogenic potential of this combination is currently unknown, females who are pregnant or lactating are excluded.
9. Females at reproductive age must have a negative urine pregnancy test prior to entry to this study.
