Decitabine + Cedazuridine + Enzalutamide for Prostate Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a combination of medications to determine the optimal dose and effects for treating prostate cancer that has spread and resists standard hormonal treatments. It examines the use of decitabine/cedazuridine (a combination drug) with enzalutamide (a hormonal therapy) to overcome the cancer's resistance to enzalutamide alone. Men with prostate cancer that no longer responds to usual treatments and is spreading might be suitable candidates, especially if they currently take enzalutamide. As a Phase 1 trial, the research aims to understand how the treatment works in people, offering participants the chance to be among the first to receive this new combination therapy.
Do I have to stop taking my current medications for the trial?
You may need to stop taking certain medications, especially if they are strong inducers or inhibitors of CYP3A4/5, at least 7 days before starting the trial. It's best to discuss your current medications with the trial team to see if any adjustments are needed.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that combining decitabine and cedazuridine is generally as safe as other similar treatments, meaning most people tolerate them well. Some side effects may occur, but they are typical for chemotherapy drugs. Studies indicate that enzalutamide can lower the risk of death in prostate cancer patients. It is usually safe, though it may cause some side effects, like most medications.
Overall, both treatments are considered manageable in terms of safety, with careful monitoring advised. Prospective trial participants should discuss these findings with their doctor to make an informed decision.12345Why are researchers excited about this study treatment for prostate cancer?
Researchers are excited about the combination of decitabine, cedazuridine, and enzalutamide for prostate cancer because it offers a novel approach by combining epigenetic modification with hormone therapy. Decitabine and cedazuridine work together to inhibit DNA methylation, potentially reactivating genes that suppress tumor growth, while enzalutamide targets androgen receptors to block the effects of male hormones that can fuel cancer. This dual-action strategy could enhance the effectiveness of prostate cancer treatment, offering hope for better outcomes compared to the current standard of care, which typically focuses on hormone therapy alone.
What evidence suggests that this trial's treatments could be effective for prostate cancer?
Studies have shown that enzalutamide can significantly improve survival for prostate cancer patients. Specifically, men taking enzalutamide had a 61% lower chance of their cancer worsening compared to those not taking it. Other research found that enzalutamide reduced the risk of death by 33% compared to a group not receiving the treatment. The combination of decitabine and cedazuridine has also shown promise, with patients having certain blood cancers living a median of 31.7 months. In this trial, participants will receive both enzalutamide and the combination of decitabine and cedazuridine. Together, these treatments might help overcome resistance to enzalutamide alone, potentially offering a new way to manage advanced prostate cancer.16789
