What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests the effectiveness of a drug called darolutamide when combined with standard hormone therapy (Androgen Deprivation Therapy, or ADT) for prostate cancer that has spread. The goal is to determine if this combination is more effective and safe compared to a placebo with ADT. It targets patients diagnosed with metastatic prostate cancer who began hormone therapy no more than 12 weeks ago. Participants must have good overall health and be able to take oral medication. As a Phase 3 trial, this study serves as the final step before FDA approval, offering participants an opportunity to contribute to potentially groundbreaking treatment advancements.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it does exclude those who have used certain prostate cancer treatments or high-dose corticosteroids recently. It's best to discuss your specific medications with the trial team.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that darolutamide, when combined with androgen deprivation therapy (ADT), is generally safe. In previous studies, most side effects were mild, with common issues including rash, fatigue, hot flashes, and sweating. Only about 7.4% of patients experienced moderate side effects, such as more intense fatigue or rash, while serious side effects were rare.

Darolutamide has also been well tolerated over extended periods. Even with long-term use, patients did not encounter many serious health problems. This track record can help instill confidence in the treatment's safety. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for prostate cancer?

Researchers are excited about darolutamide for prostate cancer because it offers a unique mechanism of action compared to current treatments. Unlike other therapies that primarily target androgen production, darolutamide acts as an androgen receptor inhibitor, blocking the effects of male hormones that fuel cancer growth. This dual approach, when combined with Androgen Deprivation Therapy (ADT), potentially enhances treatment effectiveness by attacking the cancer on two fronts. Additionally, darolutamide is designed to minimize some of the side effects associated with other androgen receptor inhibitors, making it a promising option for patients seeking effective and manageable treatment.

What evidence suggests that darolutamide + ADT might be an effective treatment for prostate cancer?

In this trial, participants will receive either a combination of darolutamide with androgen deprivation therapy (ADT) or a placebo with ADT. Research has shown that combining darolutamide with ADT can significantly improve outcomes for prostate cancer patients. Specifically, studies have found that this combination increases the time patients live without their cancer worsening by 40% compared to those taking a placebo. This allows patients to go longer without their cancer progressing. Additionally, darolutamide effectively lowers PSA levels, which are used to monitor prostate cancer. These findings strongly suggest that this treatment could be effective for prostate cancer that has spread and still responds to hormone therapy. ^{2 3 6 7 8}

Are You a Good Fit for This Trial?

Men with confirmed metastatic hormone-sensitive prostate cancer, who have started ADT within the last 12 weeks and are in good physical condition (ECOG PS of 0-2) can join. They must not have had certain heart conditions or other cancer treatments like chemotherapy for prostate cancer in the past 6 months.

Inclusion Criteria

My bone marrow, liver, and kidneys are functioning well.

I started hormone therapy for cancer not more than 12 weeks ago.

Exclusion Criteria

I have not had radiotherapy in the last 2 weeks.

I cannot swallow pills.

I have not used specific hormone therapies, chemotherapy, or other treatments for prostate cancer recently.

Up to 55 months

What Are the Treatments Tested in This Trial?

Interventions

• Androgen Deprivation Therapy (ADT)
• Darolutamide

Trial Overview

The trial is testing if adding Darolutamide to standard ADT improves outcomes for men with metastatic hormone-sensitive prostate cancer compared to ADT alone. Participants will either receive Darolutamide or a placebo alongside their regular ADT treatment.

How Is the Trial Designed?

Group I: Darolutamide+ADT Experimental Treatment 2 Interventions

Participants will receive darolutamide 600 mg (2 tablets of 300 mg) twice daily with food and ADT of investigator's choice as standard therapy

Group II: Placebo+ADT Placebo Group 2 Interventions

Participants will receive placebo twice daily with food and ADT of investigator's choice as standard therapy

Androgen Deprivation Therapy (ADT) is already approved in European Union, United States, Canada for the following indications:

Approved in European Union as Androgen Deprivation Therapy for:

• Prostate cancer
• Metastatic prostate cancer
• Non-metastatic high-risk prostate cancer

Published Research Related to This Trial

Darolutamide is an FDA-approved nonsteroidal androgen inhibitor specifically for treating castration-resistant non-metastatic prostate cancer, providing a new option for patients whose PSA levels are rising despite low testosterone.

When used alongside androgen deprivation therapy (ADT), darolutamide, like other newer agents in its class, has been shown to prolong metastasis-free survival and median survival, making it an effective treatment choice.

Using darolutamide in advanced prostate cancer: How I Do It. Hamilton, J.[2021]

In a phase 3 trial with 1306 patients suffering from metastatic, hormone-sensitive prostate cancer, the addition of darolutamide to standard treatment significantly reduced the risk of death by 32.5% compared to placebo, indicating its efficacy in improving overall survival.

The safety profile of darolutamide was comparable to placebo, with similar rates of adverse events, suggesting that it can be safely combined with androgen-deprivation therapy and docetaxel without increasing the risk of severe side effects.

Darolutamide, an oral androgen receptor inhibitor, significantly improves overall survival in patients with metastatic hormone-sensitive prostate cancer when combined with androgen deprivation therapy and docetaxel, compared to placebo.

The treatment with darolutamide has a manageable safety profile, with adverse events aligning with those typically seen in androgen deprivation therapy and docetaxel, making it a viable option for patients with high-volume disease.
