About this study

Official title: Role of Pioglitazone Therapy in Management of Insulin Resistance Associated With Androgen Deprivation Therapy (ADT) in Patients With Prostate Cancer

This study is being done to establish the mechanisms underlying insulin resistance (reduced insulin action that can lead to high blood sugar and maybe diabetes) in patients undergoing androgen deprivation therapy (ADT) for prostate carcinoma as well as to investigate the role of pioglitazone therapy in reduction/ reversal of that insulin resistance

Read the detailed description

This is a single-center, cross-sectional then prospective, randomized single-blinded study with 2 groups of subjects. One group will be men with prostate cancer in various stages of ADT and the other group will be men with prostate cancer not on ADT as control group.

Patients interested in participating who meet the inclusion/exclusion criteria and who agree to undergo blood draws and fat biopsy will be identified from the Genito-urinary oncology and urology clinics. These patients will be referred to the Diabetes and Endocrinology Research Center of WNY where they will undergo blood draws in fasting state.

On the screening day, participants will be asked to complete the informed consent, medical history and physical exam, and non-fasting blood draws (for CBC, CMP and HbA1c) prior to participating in the study. 30 ml of blood will be drawn at this visit.

Subjects who qualify and consent to take part in the study will be called in for the baseline study visit where they will undergo blood draws in fasting state. HOMA-IR method will be used to determine insulin resistance. Subcutaneous fat biopsies will be performed in all patients.

Within the ADT group, subjects will be assigned a number by a computerized simple random number generation program (Excel, Microsoft Inc.) and will be randomized (1:1) to receive either pioglitazone or placebo. The patient will be blinded to the treatment, however, the research team will not. Subjects will be given a 12 week supply of pioglitazone 30 mg or placebo pills containing cellulose that will take once a day in morning. Subjects who develop side effects (weight gain, pedal edema) on the 30 mg dose will be asked to reduce the dose to 15 mg.

Subjects will then return to the research center in 12 weeks for visit 2 where the fasting blood draws and subcutaneous fat biopsies will be performed again. The subjects will then be discharged from the study and follow with their physicians. Subject will receive a phone call after 1 and 4 weeks following start of treatment to collect any safety data. Patients will be instructed to call the research center anytime they have a question or side effects.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Pioglitazone 30 mg in people with Prostate Cancer and Insulin Resistance, run by State University of New York at Buffalo at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 15 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

HOMA-IR (time frame: 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Aug 2023.
