Trial Summary

What is the purpose of this trial?

This trial is testing darolutamide, a new drug added to standard hormone therapy, in men with high-risk localized prostate cancer undergoing radiation. The goal is to see if this combination can better prevent the cancer from coming back and spreading compared to current treatments. Darolutamide works by blocking male hormones that help cancer grow, potentially reducing death rates from prostate cancer.

Do I need to stop my current medications for this trial?

The trial requires stopping certain medications before starting the study treatment. If you are taking a first-generation nonsteroidal antiandrogen (NSAA) or a 5-alpha reductase inhibitor, you must stop these before beginning the trial. The protocol does not specify other medications, so it's best to discuss with the study team.

What data supports the effectiveness of the treatment Darolutamide + Standard Therapy for Prostate Cancer?

Recent studies have shown that combining external beam radiotherapy (a type of radiation treatment) with androgen deprivation therapy (a treatment that lowers male hormone levels) can improve survival in men with advanced prostate cancer. ^{1 2 3 4 5}

Is Darolutamide + Standard Therapy for Prostate Cancer safe for humans?

The research articles mention that external beam radiation therapy (EBRT) and androgen deprivation therapy (ADT), which are part of standard prostate cancer treatments, can have adverse effects such as issues with bowel, bladder, and sexual function. However, specific safety data for Darolutamide itself is not provided in these articles. ^{3 6 7 8 9}

How is the treatment of Darolutamide with External Beam Radiotherapy unique for prostate cancer?

The combination of Darolutamide, a drug that blocks male hormones, with External Beam Radiotherapy (EBRT) is unique because it integrates a medication that targets hormone pathways with a precise radiation treatment, potentially enhancing effectiveness compared to using radiation or hormone therapy alone. ^{4 8 10 11 12}

Eligibility Criteria

Men over 18 with high-risk localized prostate cancer, eligible for radiation therapy and at very high risk of recurrence. They must have a specific type of prostate cancer (adenocarcinoma), certain PSA levels, and no evidence of metastatic disease or previous potent AR inhibition treatments. Participants need good organ function, performance status, and must be willing to follow study procedures.

Inclusion Criteria

I am a man over 18 with a prostate cancer diagnosis.

You are willing to complete HRQL questionnaires unless you are unable to complete due to literacy or limited vision.

Exclusion Criteria

Prostate cancer with predominant non-adenocarcinoma features (sarcomatoid or spindle cell or neuroendocrine small cell or squamous cell components or other non-adenocarcinoma),Involvement of LNs by conventional CT imaging superior to the common iliac artery bifurcation, and/or outside the pelvis (distant LNs). LN involvement is defined by histopathological confirmation, or by a short axis measurement > 10mm on standard imaging (CT or MRI, but not PET).,Evidence of metastatic disease. Minimum imaging requirements to exclude metastatic disease are diagnostic quality imaging of both the pelvis and the abdomen (CT or MRI), chest (CXR or CT), and a whole body radioisotope bone scan (WBBS).,If endocrine therapy (ET) had not started, imaging must be within 60 days prior to randomisation.,If ET has been started, imaging must have been performed no more than 60 days prior to starting ET and no more than 30 days after starting ET and prior to randomisation.,PSA > 100 ng/mL at any time,Any prior use of new generation potent AR inhibition (abiraterone, enzalutamide, apalutamide, darolutamide or similar agents).,Prior endocrine therapy for prostate cancer except for the following which are allowed: (i) LHRHA and/or (ii) a first-generation nonsteroidal antiandrogen (NSAA) are allowed if commenced no more than 90 days before randomisation. If an NSAA has been used, it must be stopped before starting study treatment with darolutamide/placebo; and Prior use of 5-alpha reductase inhibitor is allowed and if used it must be stopped before starting study treatment with darolutamide/placebo,Bilateral orchidectomy,Prior pelvic brachytherapy or other radiotherapy that would result in an overlap of radiotherapy fields that would preclude the required RT,History of Loss of consciousness or transient ischemic attack or stroke within 6 months prior to randomisation, or Significant cardiovascular disease within 6 months prior to randomisation: including myocardial infarction, unstable angina, congestive heart failure (NYHA grade II or greater), ongoing arrhythmias of Grade > 2 (CTCAE v5.0), thromboembolic events (e.g. deep vein thrombosis, pulmonary embolism), coronary artery bypass graft.

Findings from Research

In a study of 46,325 men with high-risk prostate cancer, androgen deprivation therapy (ADT) improved overall survival for those receiving external beam radiation therapy (EBRT) alone, but not for those receiving combined EBRT and brachytherapy.

The findings suggest that while ADT is beneficial with EBRT, it may not enhance survival in patients treated with both EBRT and brachytherapy, highlighting the need for further research to evaluate the risks and benefits of ADT in this context.

Lack of Apparent Survival Benefit With Use of Androgen Deprivation Therapy in Patients With High-risk Prostate Cancer Receiving Combined External Beam Radiation Therapy and Brachytherapy. Yang, DD., Muralidhar, V., Mahal, BA., et al.[2018]

In a study of 585 high-risk prostate cancer patients treated with high-dose external beam radiotherapy (EBRT) and androgen deprivation therapy (ADT), a biopsy Gleason score (bGS) of 8 to 10 was identified as the strongest predictor of biochemical relapse-free survival (bRFS), distant metastases-free survival (DMFS), and prostate cancer-specific mortality (PCSM).

The study found that the duration of ADT did not significantly impact patient outcomes, highlighting the importance of tumor characteristics over treatment length in predicting survival rates.

Redefining high-risk prostate cancer based on distant metastases and mortality after high-dose radiotherapy with androgen deprivation therapy. Tendulkar, RD., Reddy, CA., Stephans, KL., et al.[2020]

A study of 1,825 men with prostate cancer treated with external beam radiation therapy (EBRT) found that location of treatment significantly influenced the level of adverse effects, with one regional cancer service reporting a higher 'big bother' rate (11.1%) compared to the rest of Victoria (4.8%).

The study indicates that while the technique of EBRT did not show a significant impact on patient outcomes over time, the variation in patient-reported adverse effects highlights the importance of monitoring and evaluating treatment locations for better patient care.

Prospective evaluation of patient-reported quality of life outcomes after external beam radiation treatment for prostate cancer in Victoria: A cohort study by the Victorian Prostate Cancer Registry. Patabendi Bandarage, VR., Billah, B., Millar, JL., et al.[2018]

In a study of 173 patients with high-risk localized prostate cancer, long-term androgen deprivation therapy (ADT) for 36 months or more combined with external-beam radiotherapy (EBRT) significantly improved five-year progression-free survival rates (92.8%) compared to short-term ADT (72.9%).

Patients receiving short-term ADT experienced a higher incidence of cardiovascular toxicity (grade II or above) compared to those on long-term ADT, indicating that longer ADT may not only enhance survival but also have a more favorable safety profile.

Impact of the duration of hormonal therapy following radiotherapy for localized prostate cancer. Okubo, M., Nakayama, H., Itonaga, T., et al.[2022]

In a study of 215 patients with locally advanced prostate cancer, 97.5% of those treated with external beam radiation therapy (EBRT) showed no biochemical failure after a mean follow-up of 17.3 months, indicating high efficacy of the treatment protocol.

The study suggests that intermittent androgen ablation therapy after EBRT may be a viable option, although the follow-up period was short and further research is needed to confirm long-term outcomes.

A survey of 42 North American genitourinary physicians revealed a significant divide in treatment recommendations for high-risk prostate cancer, with 45% supporting the addition of brachytherapy (BT) boost to external beam radiation therapy (EBRT) and androgen deprivation therapy (ADT), while 55% preferred EBRT and ADT alone.

Experts in brachytherapy were much more likely to recommend the BT boost, indicating that physician expertise significantly influences treatment decisions, which may impact future clinical guidelines and studies in prostate cancer management.
