简要总结
This research study is comparing the use of a new form of hormonal therapy used with radiation as a possible treatment for intermediate risk prostate cancer. More specifically, this research would help determine whether this new form of hormonal therapy is as effective as the standard hormone therapy while also preserving erectile function.
详细描述
This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific disease. "Investigational" means that the drug is being studied.
In this research study, the investigators are looking at whether the novel form of hormonal therapy, called Darolutamide, when paired with radiation therapy will provide the same quality of care as the current standard treatments available for men with this type of cancer. Darolutamide prevents testosterone from signaling throughout the body. Although studies have shown that Darolutamide has activity in more advanced forms of prostate cancer, the activity of Darolutamide is unknown in intermediate risk prostate cancer treated with radiation therapy. The U.S. Food and Drug Administration (FDA) has not approved Darolutamide as a treatment for any disease.
The current standard of care treatments available to men with this type of cancer are radiation therapy with or without androgen deprivation therapy (ADT) involving a gonadotropin releasing hormone agonist plus bicalutamide (both FDA-approved) or surgery. ADT works by depriving the body of testosterone which "feeds" prostate cancer cells and weakens prostate cancer cells from repairing damage caused by radiation therapy.
In addition, the investigator will be assessing erectile function at baseline, during and after treatment to determine if short-term erectile function can be preserved without sacrificing long-term disease control.

入选标准
- •Histologically confirmed prostate adenocarcinoma by biopsy within 1 year (365 days) from registration. The most recent biopsy will determine eligibility
- •National Cancer Center Network (NCCN) intermediate risk prostate cancer, defined as clinical T2b-T2c, Gleason 7, or PSA 10-20 ng/mL. Patients who only have radiographic evidence of T3 disease (i.e. extracapsular extension, or seminal vesical invasion radiographically) will not be excluded.

- •2-3 intermediate risk factors
- •Gleason 7
- •PSA 10-20 ng/mL
- •Gleason 4+3 disease
- •Percent positive cores ≥ 50%

- •Able to undergo radiation therapy with curative intent
- •Age ≥ 18 at the time of consent.
- •Demonstrate adequate organ function (hematologic, renal, hepatic) within 3 months of registration

- •Absolute neutrophil count (ANC) ≥ 1000 cells/µL
- •Glomerular filtration rate (GFR) ≥ 45 mL/min
- •CKD-EPI equation will be used to calculate GFR
- •Hepatic and Other:
- •Bilirubin ≤ 1.5 × upper limit of normal (ULN)
- •In subjects with Gilbert's syndrome, if total bilirubin is >1.5 × ULN, measure direct and indirect bilirubin; if direct bilirubin is ≤1.5 × ULN, subject may be eligible
- •Aspartate aminotransferase (AST) ≤ 2.5 × ULN
- •Alanine aminotransferase (ALT) ≤ 2.5 × ULN
- •Serum Albumin > 3.0 g/dL
- •Serum potassium ≥ 3.5 mmol/L
- •Endocrine:
- •Testosterone ≥ 150 ng/dL
- •Eastern Cooperative Oncology Group (ECOG) performance status of 0-1
- •Good erectile function, as assessed by 'firm enough for masturbation or foreplay' or 'firm enough for intercourse' response to the question "How would you describe the usual quality of your erections during the past 4 weeks" on the EPIC-26 questionnaire
- •Agrees to use a condom and another effective method of birth control if he is having sex with a woman of childbearing potential (defined as a premenopausal female capable of becoming pregnant) OR agrees to use a condom if he is having sex with a woman who is pregnant while on study drug and for 3 months following the last dose of study drug. It is recommended that men who have had a vasectomy more than a year prior to trial registration use a condom. Must also agree not to donate sperm.
- •Ability to understand and comply with study procedures for the entire length of the study as determined by the site investigator or protocol designee
- •Written informed consent and HIPAA authorization for release of personal health information prior to registration. Note: HIPAA authorization may be included in the informed consent or obtained separately. Subject must have the ability to understand and willingness to sign the written informed consent document.
- •Ability to swallow pills.
- •For patients in whom SBRT/combination RT stratification is pre-specified, prostate volume as determined by MRI, CT, or ultrasound to be less than 90 cc.
排除标准
- •Prior surgical, cryotherapy, or high-intensity focused ultrasound for prostate cancer
- •Prior orchiectomy or hormonal therapy (gonadotropin releasing hormone (GnRH) agonists, non-steroidal anti-androgens)
- •Prior treatment with a first generation AR inhibitor (e.g. bicalutamide, flutamide, nilutamide, cyproterone acetate) or second generation AR inhibitor (e.g.Enzalutamide, Apalutamide, or Darolutamide)
- •Prior treatment with other investigational AR inhibitors, CYP17 enzyme inhibitor such as abiraterone acetate, TAK-700, or oral ketoconazole longer than 28 days
- •Prior use of estrogens; patients who have used testosterone injections must have ceased utilization within 90 days prior to screening testosterone.

- •Use of 5-α reductase inhibitors (finasteride, dutasteride) within 28 days of randomization.
- •Prior radiation therapy that would result in overlap of current radiation therapy fields
- •Prior chemotherapy for prostate cancer
- •Clinically positive lymph nodes by imaging, sampling, or dissection. Patients with lymph nodes greater than 1.5 cm on short axis will require a negative biopsy for eligibility.
- •Metastatic disease, as assessed by abdominal or pelvic computed tomography (CT) or other imaging modality. Patients with 3 intermediate risk factors will require a CT abdomen/pelvis and a bone scan or PET imaging (PSMA PET/CT, fluciclovine PET/CT, etc.).
