Comparing hormone therapy with radiation to radiation alone for prostate cancer

Official title: A Phase II Prospective 2-Arm Cohort Interventional Trial Utilizing Ultra-Hypofractionated SBRT With or Without Short Course Androgen Deprivation Therapy For Unfavorable Intermediate Risk Prostate Cancer

Run by NYU Langone Health · NCT06397703 · Data updated 2026-11-12

This study is testing whether adding hormone therapy to radiation treatment can help men with certain types of prostate cancer do better than just using radiation alone.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are men diagnosed with unfavorable intermediate risk prostate cancer who meet specific clinical criteria.

Probably not a fit

Patients with favorable risk prostate cancer or those who do not meet the eligibility criteria may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effectiveness of combining six months of androgen deprivation therapy (ADT) with stereotactic body radiation therapy (SBRT) versus using SBRT alone in patients with unfavorable intermediate risk prostate cancer. Participants will be followed for up to five years to assess local tumor control through routine biopsies and clinical evaluations. The study aims to determine if the addition of ADT improves treatment outcomes for this specific patient population. Eligible patients must have specific characteristics defined by the National Comprehensive Cancer Network (NCCN).

Why it matters

Potential benefit: If successful, this approach could lead to improved treatment outcomes and better management of unfavorable intermediate risk prostate cancer.

How similar studies have gone: Other studies have explored similar combinations of ADT and radiation therapy, showing promising results, but this specific approach is being evaluated in a novel context.

* Adequate renal function with serum creatinine less than or equal to 1.5 x ULN
* Adequate hematologic function with absolute neutrophil counts of at least 1,500 cell/mm3 and platelets of at least 100,000 cells/mm3 and hemoglobin value \> 9 g/dL (Note: patients whose anemia has been corrected to a hemoglobin value \> 9 g/dL with blood transfusions are allowed).

Exclusion Criteria:

* CT or MRI or Positron Emission Tomography (PET) scan evidence of metastatic disease to the bone
* Patients with one or more positive lymph nodes considered suspicious as determined by clinical assessment on MRI or CT or PET scan
* Prior treatment for prostate cancer, including history of chemotherapy, hormonal therapy within 30 days of enrollment or surgery for prostate cancer (except for prior (transurethral resection of prostate) TURP or greenlight (photoselective vaporization of prostate) PVP which would be allowed)
* History of another malignancy within the previous 2 years except for the following: adequately treated basal cell or squamous cell skin cancer, superficial bladder cancer, currently in complete remission, or any other cancer that has been in complete remission for at least 3 years
* Patients with Crohn's disease or ulcerative colitis
