Zolpidem Pharmacokinetics in Prostate Cancer Patients Undergoing Androgen Deprivation Therapy
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to understand how the sleep medication zolpidem (Ambien) behaves in the bodies of men with prostate cancer undergoing hormone therapy compared to healthy women. Researchers are examining how prostate cancer treatments might alter zolpidem levels, which could help determine the best dose for different groups. Men with prostate cancer starting androgen deprivation therapy, as well as healthy women, may be suitable candidates for this study. Participants will take zolpidem and undergo tests to track how their bodies process the drug. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants a chance to contribute to foundational knowledge.
Will I have to stop taking my current medications?
The trial requires that participants stop taking certain medications. Male participants cannot take medications that affect zolpidem metabolism, like strong CYP3A4 inhibitors or inducers. Female participants must not be on regular medications, except contraceptives, within two weeks before the study.
Is there any evidence suggesting that zolpidem is likely to be safe for humans?
Research has shown that zolpidem, also known as Ambien, is usually safe for use. Studies indicate it rarely causes serious side effects, and most people taking zolpidem do not experience major problems. Some might feel mild effects like dizziness or drowsiness. Zolpidem is already FDA-approved for treating insomnia, indicating its safety for this purpose. If any side effects occur during the trial, researchers will closely monitor participants.12345
Why do researchers think this study treatment might be promising?
Researchers are excited about using zolpidem in prostate cancer patients undergoing androgen deprivation therapy (ADT) because it explores a unique interaction between sleep aids and cancer treatment. Unlike typical treatments for prostate cancer, which primarily focus on hormone suppression, this study looks at zolpidem, a well-known sleep medication, to see how it behaves in the body before and after ADT. This could lead to better management of sleep issues in cancer patients, potentially improving their quality of life during treatment. By understanding zolpidem's pharmacokinetics in this context, researchers hope to tailor sleep aid regimens specifically for prostate cancer patients on ADT.
What evidence suggests that zolpidem might be an effective treatment for insomnia in prostate cancer patients undergoing androgen deprivation therapy?
Studies have shown that zolpidem helps adults fall asleep and stay asleep. In individuals with solid tumors, such as prostate cancer, zolpidem has improved sleep quality. This medication acts as a strong sedative, promoting relaxation and better sleep. The trial focuses on understanding zolpidem's effects in the body, particularly when prostate cancer treatment reduces male hormone levels. Participants will receive zolpidem either as a single 5 mg oral dose or in a regimen before and after undergoing androgen deprivation therapy. Research suggests that women may have higher levels of zolpidem in their system after taking it, potentially affecting how they feel the next day.12367

Are You a Good Fit for This Trial?
Men over 18 with prostate cancer planning to undergo androgen deprivation therapy, and healthy women over 18 can join. Participants must have normal organ function, not be on certain medications or have other cancers, serious illnesses, or psychiatric conditions that could affect the study.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment - Pre-ADT
Participants receive a single 5 mg dose of zolpidem followed by an 8-hour pharmacokinetic evaluation
Treatment - Post-ADT
After undergoing androgen deprivation therapy and reaching castrate testosterone levels, participants receive another 5 mg dose of zolpidem followed by an 8-hour pharmacokinetic evaluation
Follow-up
Participants receive a follow-up phone call after each overnight stay to monitor for any adverse events
What Are the Treatments Tested in This Trial?
Interventions
- Zolpidem
Trial Overview
The trial is testing how castration affects the levels of Zolpidem in men with prostate cancer compared to its levels in healthy women. Men will take Zolpidem before and after their testosterone-lowering treatment; both groups will stay overnight for monitoring.
How Is the Trial Designed?
2
