Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the drug Flutamide for prostate cancer?

Research shows that flutamide is effective in treating advanced prostate cancer, with response rates similar to traditional hormone therapy and improvements in symptoms and quality of life. Additionally, combining flutamide with other treatments like Zoladex can lead to quicker relief of symptoms, although it may also increase side effects.12345

Is flutamide safe for humans?

Flutamide has been studied for safety in prostate cancer patients, with some experiencing mild to moderate side effects. However, it can cause liver issues, especially in those with existing liver problems, and some patients have stopped treatment due to side effects.12678

How does the drug flutamide differ from other treatments for prostate cancer?

Flutamide is a non-steroidal anti-androgen that works by blocking the action of male hormones (androgens) which can fuel the growth of prostate cancer. Unlike some other treatments, it can be used in combination with an LHRH agonist to enhance effectiveness, and it generally does not affect libido or sexual potency.123910

What is the purpose of this trial?

This is a prospective, single-center, two-phase study to assess the efficacy of single pulsed-dose flutamide in creating double strand breaks (DSBs) in prostate cancer within patients receiving central androgen suppression and brachytherapy.

Eligibility Criteria

Men with prostate cancer who've chosen brachytherapy and androgen suppression as treatments can join. They need to have a certain amount of detectable disease for biopsy, confirmed by tests, including at least one biopsy core with Gleason 7 or higher. Participants must sign a consent form. Those with severe liver issues, allergies to flutamide, or major illnesses that could affect treatment aren't eligible.

Inclusion Criteria

Signed study-specific consent form prior to registration
My prostate cancer diagnosis was confirmed through a tissue examination.
I have a tumor that can be felt and biopsied.

Exclusion Criteria

Known hypersensitivity or allergic response to flutamide
I have severe liver problems.
Major medical or psychiatric illness which, in the investigator's opinion, would prevent completion of treatment and would interfere with follow up.

  • Flutamide
Trial Overview The study is testing if a single dose of the drug flutamide can cause double strand breaks in DNA within prostate cancer cells during standard treatment. It's compared against a placebo in men already receiving hormone therapy and brachytherapy.

Findings from Research

In a study involving 304 patients with advanced prostate cancer, there was no significant difference in overall and progression-free survival between those treated with Zoladex alone and those treated with Zoladex plus flutamide.
The combination treatment of Zoladex and flutamide resulted in a higher response rate and quicker relief of bone pain, but it also led to more side effects, suggesting that the combination may not provide a clear advantage over Zoladex alone.

In a study of 905 patients with advanced prostate cancer, flutamide was found to be safe and well tolerated, with only 2% of patients withdrawing due to severe diarrhea and 0.8% due to liver function changes.
The most common side effects included gastrointestinal issues (around 15% incidence) and hot flushes (40% in total androgen blockade groups), but no unexpected dangerous adverse events were reported.
