About this study

Official title: Phase II Trial of Estrogen Receptor Targeted Treatment of Non-Muscle Invasive Bladder Cancer With Tamoxifen.

Evaluate the treatment of tamoxifen of low/intermediate-risk bladder tumors

Read the detailed description

Patients with primary or recurrent low/intermediate-risk papillary urothelial carcinoma of the bladder will undergo resection of all but one marker lesion, measuring at least 6mm but no greater than 10mm, and biopsy of normal-appearing mucosa. Patients with a solitary tumor will undergo only biopsy prior to treatment. A 2mm cold cup biopsy of the marker lesion will always be performed to rule out a potential high-grade lesion and for assessment of pretreatment immunohistochemistry expression levels of ERα, ERβ1, Ki-67 (proliferation marker) and TUNEL (apoptosis marker). If there are multiple tumors, all lesions, except the marker lesion will be resected and sent for analysis. These patients will not receive single immediate post-operative intravesical instillation of mitomycin-C. They will then undergo a 12-week course of treatment with tamoxifen administered as a single daily oral dose of 20mg. At the completion of therapy, patients will undergo resection of the marker lesion (or biopsy of the tumor bed, if a complete response is observed) and biopsy of normal-appearing bladder mucosa again. Toxicity evaluations will be performed at the beginning (day 3), midway (week 6), and at completion of treatment (week 12), prior to resection of the marker lesion. A final assessment for toxicity will also be performed 30 days after completion of therapy as well as a second definitive resection of the marker lesion. Urine samples will be obtained with the index tumor in place (marker lesion), and after completion of treatment, at the time of definitive transurethral resection of the index tumor, as part of the standard clinical care of these patients, and at the discretion of the surgeon for assessment of urinary cytology. The urine samples will not be utilized for the research study. All normal-appearing bladder biopsies (pre and post-treatment), the additional tumors (in case of multiple lesions), and the definitive resection of the marker lesion (in the absence of response to therapy) will provide sufficient material for immunohistochemistry assessment of the expression levels of ERα, ERβ-1, ERβ-2, ERβ-5, Ki-67, and TUNEL, and also for RT-qPCR for mRNA analyses of ERα, ERβ-1, ERβ-2, and ERβ-5. The pretreatment biopsy of the marker lesion will be performed with a smaller biopsy forceps and will provide limited material, sufficient only for immunohistochemistry assessment of the expression levels of ERα, ERβ-1, Ki-67, and TUNEL.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Tamoxifen Citrate in people with Bladder Cancer, run by Baylor College of Medicine at 2 sites 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 7 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: finished, as of the sponsor's last update on 13 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 13 Jan 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Evaluate the Efficacy for Treatment of Low/Intermediate- Risk Bladder Tumors, Assessing for the Clinical Response of the Marker Lesion (time frame: 2.5 years). 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 13 Jan 2021.
