What is the mechanism of action of this treatment?

Prostate cancer treatments often target the androgen receptor pathway, which is crucial for the growth and survival of prostate cancer cells. Androgen deprivation therapy (ADT) reduces androgen levels in the body, either through surgical castration or medications like luteinizing hormone-releasing hormone analogues (LHRHAs). Androgen receptor inhibitors, such as darolutamide, enzalutamide, and apalutamide, block the androgen receptor, preventing androgens from stimulating cancer cell growth. These treatments are vital for prostate cancer patients because they effectively slow disease progression and improve survival rates by targeting the hormonal drivers of cancer growth.

What side effects are associated with this type of intervention?

Common treatments for prostate cancer that involve androgen receptor inhibition, such as darolutamide, enzalutamide, and apalutamide, have several known side effects. Darolutamide is associated with fewer central nervous system side effects compared to enzalutamide and apalutamide, which can cause fatigue, seizures, and falls. When combined with androgen deprivation therapy (ADT) and docetaxel, these treatments can also lead to increased risks of severe myelosuppression, fatigue, peripheral edema, and gastrointestinal issues like diarrhea. It is important to monitor for these side effects and manage them appropriately in consultation with a healthcare provider.

What prior FDA approvals exist?

Enzalutamide and apalutamide are two FDA-approved androgen receptor inhibitors for the treatment of prostate cancer. Enzalutamide is approved for metastatic castration-resistant prostate cancer (CRPC) and has shown to increase median survival in clinical trials. Apalutamide is approved for both nonmetastatic and metastatic castration-sensitive prostate cancer (CSPC), demonstrating significant improvements in overall survival and progression-free survival. These drugs, like darolutamide, work by inhibiting the androgen receptor, which is crucial for the growth of prostate cancer cells.

What other types of research exist?

Promising alternatives to Darolutamide for prostate cancer treatment in 2024 include Enzalutamide, Apalutamide, and Abiraterone Acetate. These therapies have demonstrated efficacy in clinical trials for both hormone-sensitive and castration-resistant prostate cancer. Additionally, combination therapies involving PARP inhibitors like Olaparib and Niraparib with androgen deprivation therapy are emerging as effective options, particularly for patients with specific genetic mutations.

Pivotal Trial

Summary

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.

Who is the study for?

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.

What is being tested?

The trial is testing the effectiveness of darolutamide in combination with standard hormone therapy using LHRHA and external beam radiotherapy in men undergoing treatment for very high-risk localized prostate cancer. The goal is to see if adding darolutamide helps prevent cancer from coming back.

What are the potential side effects?

Darolutamide may cause fatigue, digestive issues like nausea or diarrhea, skin rash, liver enzyme changes which could indicate liver damage, blood pressure changes, and can affect how other medications work.
