Inclusion criteria
. Be over 18 years of age
. Be able to communicate effectively with the study personnel
. Have histologically confirmed prostate cancer
. ECOG performance status of 0 to 2
. Have been treated with ADT(chemical or surgical) for at least 6 months
. Have castrate level of serum total testosterone (\<50 ng/dL)

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
. Have rising serum PSA on two successive assessments at least 2 weeks apart and serum PSA levels ≥ 2 ng/mL or 2ng/mL and a 25% increase over the nadir after the initiation of ADT
Exclusion criteria
. Known hypersensitivity or allergy to estrogen or estrogen like drugs;
. Have symptomatic metastatic prostate cancer
. Any disease or condition (medical or surgical) which might compromise the hematologic, cardiovascular, endocrine, pulmonary, renal, gastrointestinal, hepatic, or central nervous system; or other conditions that may interfere with the absorption, distribution, metabolism or excretion of study drug, or would place the subject at increased risk;
. History of abnormal blood clotting, Factor V Leiden clotting disorder, thrombotic disease (venous or arterial thrombotic events such as history of stroke, deep vein thrombosis (DVT), and/or pulmonary embolus (PE))
. Symptomatic congestive heart failure (NYHA Class III - IV), unstable angina pectoris, cardiac arrhythmia
. The presence of consistently abnormal laboratory values which are considered clinically significant. In addition, no subject with liver enzymes (ALT or AST) above 2 times the ULN, total bilirubin above 2 times the ULN, or serum creatinine above 1.5 ULN will be admitted to the study
. Received an investigational drug within a period of 90 days prior to enrollment in the study
