What You Need to Know Before You Apply

What is the purpose of this trial?

This trial investigates the effectiveness of combining androgen-ablation therapy with chemotherapy for treating metastatic prostate cancer. Androgens can fuel prostate cancer growth, so androgen-ablation therapy aims to stop these hormones from being produced. The trial will compare this approach alone to its combination with docetaxel, a chemotherapy drug that kills cancer cells or stops them from dividing. Ideal participants are men with metastatic prostate cancer who have been on androgen-deprivation therapy for less than four months. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance 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. However, concurrent antiandrogen therapy is allowed, but not as the only hormonal therapy. 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 combining hormone therapy with the chemotherapy drug docetaxel has been tested for safety in treating prostate cancer. Studies indicate that this combination can extend the lives of patients with advanced prostate cancer.

Safety information from these studies suggests that the treatment is generally well-tolerated. However, like most cancer treatments, some patients experienced side effects, such as tiredness, nausea, and lower blood cell counts, which are common with chemotherapy. Despite these side effects, the treatment offers significant benefits in managing cancer.

Previous patients who received this combination therapy demonstrated that it is a practical option with manageable risks for many. It is important to discuss any concerns with a healthcare provider before considering joining a clinical trial.12345

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

Researchers are excited about combining androgen-deprivation therapy with docetaxel for prostate cancer because it offers a potentially more powerful approach than standard hormone therapy alone. Androgen-deprivation therapy typically reduces male hormones that fuel cancer growth, but adding docetaxel, a chemotherapy drug, provides a double punch by directly attacking cancer cells. This combination could lead to better outcomes by slowing disease progression more effectively than hormone therapy alone.

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

Research has shown that combining hormone therapy with the chemotherapy drug docetaxel can benefit people with prostate cancer that has spread. In this trial, one group of participants will receive both androgen-deprivation therapy and docetaxel, while another group will receive only androgen-deprivation therapy. Studies have found that adding docetaxel to hormone therapy can extend life compared to hormone therapy alone. Specifically, one study found that starting treatment with six cycles of docetaxel led to longer survival. Another study demonstrated that this combination not only extended life but also delayed cancer progression. This suggests that using both treatments together can be more effective than hormone therapy alone.26789

Are You a Good Fit for This Trial?

This trial is for men with metastatic prostate cancer who have not been on androgen-deprivation therapy for more than 120 days. They should be in good enough health to participate, as indicated by specific blood counts and organ function tests. Men must agree to use contraception, and they can't join if they've had certain other cancers or heart problems, severe allergies to docetaxel components, or prior hormone therapy in the metastatic setting.

Inclusion Criteria

PS 2 eligible only if decline in PS is due to metastatic prostate cancer

Exclusion Criteria

Prior hormone therapy in the metastatic setting
Active cardiac disease, including the following:
Prior malignancy in the past 5 years except for basal cell or squamous cell carcinoma of the skin

Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Treatment

Participants receive androgen-deprivation therapy with or without docetaxel chemotherapy. Docetaxel is administered intravenously every 21 days for up to 6 courses.

18 weeks

Follow-up

Participants are monitored for safety and effectiveness after treatment. Follow-up includes assessments every 3 months for the first 2 years, every 6 months for the next 3 years, and annually thereafter.

Up to 10 years

What Are the Treatments Tested in This Trial?

Interventions

  • Androgen-deprivation therapy
  • Docetaxel
Trial Overview The study is testing whether adding chemotherapy (docetaxel) to standard hormone treatment (androgen-ablation therapy) improves outcomes for men with advanced prostate cancer. Participants are randomly assigned to receive either both treatments or just the hormonal therapy alone.

Published Research Related to This Trial

Combination hormonal therapy, which achieves 'total androgen blockade,' has shown superior efficacy compared to monotherapy in treating patients with low-tumor-burden metastatic prostate cancer.
Emerging phase II studies indicate that this combination therapy may also benefit patients with locally advanced prostate cancer by prolonging disease-free survival, with ongoing phase III trials to further evaluate its effectiveness.
Hormonal Therapy for Prostate Cancer: When to Use It.Einstein, AB.[2019]
In a study of 548 men with prostate cancer, both primary androgen-deprivation therapy (PADT) and salvage medical ADT (SADT) were found to prolong overall survival (OS) and disease-specific survival (DSS), but there was no significant difference in survival outcomes between the two treatment groups.
Most deaths in the study were due to causes unrelated to prostate cancer, suggesting that while ADT can extend survival, its impact on prolonging life specifically from cancer may be limited, especially in patients who progress to hormone-refractory prostate cancer (HRPC), which significantly worsens survival outcomes.
