What You Need to Know Before You Apply

What is the purpose of this trial?

This trial examines the safety and effectiveness of two drug combinations for treating metastatic hormone-sensitive prostate cancer (mHSPC), which is prostate cancer that has spread but still responds to hormone therapy. Participants will receive tulmimetostat (an experimental treatment) with either Abiraterone or Darolutamide to evaluate the effectiveness of these combinations. Men diagnosed with mHSPC, who have at least one metastatic lesion and are already on hormone therapy, might be suitable for this study. As a Phase 1, Phase 2 trial, this research aims to understand how the treatment works in people and measure its effectiveness in an initial, smaller group, offering participants the opportunity to contribute to groundbreaking advancements in prostate cancer treatment.

Do I need to stop taking my current medications to join the trial?

The trial requires that you stop taking certain medications, such as first-generation anti-androgens and systemic ketoconazole, before joining. Herbal products that may lower PSA levels must also be stopped 4 weeks before starting the study treatment. If you're taking any prohibited medications, you need to stop them 7 days before the study treatment.

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

Previous studies have shown that darolutamide helps patients with prostate cancer live longer, with side effects similar to those of a placebo, indicating it is generally well-tolerated. Abiraterone, already approved for prostate cancer, has been extensively studied. Research has shown it is safe, though some patients may experience side effects like high blood pressure or changes in liver function.

Tulmimetostat has been less studied, but ongoing research is examining its safety. Since this trial is in its early stages (Phase 1/2), researchers are beginning to understand its safety profile. Early-phase trials typically focus on safety and determining the right dose, so while detailed safety data is not yet available, the treatment is being carefully tested for safety in humans.12345

Why are researchers excited about this trial's treatments?

Researchers are excited about the combination of Tulmimetostat with Darolutamide or Abiraterone for prostate cancer because it brings a fresh approach to treatment. Unlike most treatments that target androgen receptors, Tulmimetostat is a novel drug that potentially inhibits cancer growth by modifying gene expression through epigenetic changes. This unique mechanism could offer an alternative pathway to tackling cancer cells, especially when combined with the well-established hormone therapies, Darolutamide and Abiraterone. The combination therapies might enhance effectiveness and possibly delay resistance, offering hope for improved outcomes in prostate cancer management.

What evidence suggests that this trial's treatments could be effective for metastatic hormone-sensitive prostate cancer?

Research has shown that darolutamide, when used for prostate cancer, reduces the risk of death by 32.5% and improves survival rates compared to a placebo. Abiraterone also extends patients' lives and slows disease progression in similar groups. Tulmimetostat targets specific cancer pathways, but earlier studies in prostate cancer showed no responses. In this trial, some participants will receive a combination of tulmimetostat with darolutamide, while others will receive tulmimetostat with abiraterone. Researchers are further studying these combinations to confirm their potential benefits in overcoming common resistance in prostate cancer treatment.12367

Are You a Good Fit for This Trial?

Men over 18 with metastatic hormone-sensitive prostate cancer, either new or recurrent, can join this trial. They must have low testosterone levels and a performance status showing they can handle daily activities. Participants should not have progressed on prior taxane-based therapy or be currently using darolutamide but may have used similar drugs for less than six months.

Inclusion Criteria

I've used ARPI for prostate cancer before but stopped when there was no sign of spread on scans.
I have used ARPI for my metastatic hormone-sensitive prostate cancer.
