Study Summary

This trial is testing whether adding the immunotherapy drug pembrolizumab to the chemotherapy drug gemcitabine can help to treat patients with bladder cancer that has not responded to treatment with Bacillus Calmette-Guerin (BCG).

Who is the study for?
This trial is for adults with high-grade non-muscle invasive bladder cancer that hasn't responded to BCG treatment. Candidates must have had all visible tumors removed, not be pregnant or breastfeeding, agree to birth control use, and have proper organ function. Those unfit for radical cystectomy or refusing it can join. People with certain infections, recent radiation therapy to the lungs, active autoimmune diseases, other cancers within three years, or previous treatments with similar drugs are excluded.Check my eligibility
What is being tested?
The study is testing if adding pembrolizumab (an immunotherapy drug) to gemcitabine (a chemotherapy drug) improves outcomes in patients whose bladder cancer has not improved after BCG treatment. Pembrolizumab helps the immune system fight cancer while gemcitabine works by killing or stopping tumor cells from growing.See study design
What are the potential side effects?
Pembrolizumab may cause immune-related side effects like inflammation of organs and infusion reactions; fatigue; skin rash; digestive issues such as nausea and diarrhea; liver problems; hormonal gland problems leading to hormone deficiencies. Gemcitabine can cause blood disorders, flu-like symptoms, swelling at the injection site and hair loss.

Experimental Treatment
Group I: Treatment (pembrolizumab, gemcitabine hydrochloride)Experimental Treatment2 Interventions
INDUCTION: Patients receive pembrolizumab IV over 25-40 minutes on day 1 of cycles 1-4. Patients also receive gemcitabine hydrochloride intravesically on days 1, 8 and 15 of cycles 1 and 2. Treatment repeats every 3 weeks for 4 cycles in the absence of disease progression or unacceptable toxicity. MAINTENANCE: Beginning cycle 5, patients with no evidence of disease after induction receive pembrolizumab IV over 25-40 minutes and gemcitabine intravesically on day 1. Treatment repeats every 3 weeks for 12 cycles in the absence of disease progression or unacceptable toxicity.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

How many sites have been established for this study to be conducted within the state?

"University of California Davis Comprehensive Cancer Center in Sacramento, California, Missouri Baptist Sullivan Hospital in Sullivan, Missouri and Billings Clinic Cancer Center in Billings Arizona are some of the health care centres that are recruiting participants. In total there 100 different sites taking part."

Answered by AI

To what conditions is Pembrolizumab commonly prescribed?

"Pembrolizumab is widely used to fight malignant neoplasms and other diseases like inoperable melanoma, microsatellite instability high, and non-small cell lung carcinoma."

Answered by AI

Is recruitment still open for this medical experiment?

"Yes, the available data on clinicaltrials.gov indicates that this research endeavour is actively recruiting participants. The trial commenced its recruitment efforts on June 1st 2020 and has since been updated most recently on November 22nd 2022. 161 individuals are required from 100 sites for successful completion of the study."

Answered by AI

What is the aim of this medical research project?

"The primary aim of this trial is to assess event-free survival at 18 months, while secondary objectives include assessing recurrence free survival (RFS), duration of response (DOR), and overall survival (OS). RFS will be evaluated using the Kaplan-Meier product-limit estimator, with DOR and OS also being analysed by way of the same methodology. Analyses for these outcomes are expected to occur after 6 months, or approximately 25 weeks into the clinical experiment."

Answered by AI

Has Pembrolizumab received authorization from the FDA?

"Although there is some evidence of safety, but no data confirming efficacy, our team at Power assigned Pembrolizumab a score of 2 on the scale from 1 to 3."

Answered by AI

What is the current size of enrollment for this clinical trial?

"Affirmative. Information hosted on clinicaltrials.gov supports the notion that this medical study, initially posted on June 1st 2020, is actively enrolling patients. 161 participants need to be recruited from 100 various sites."

Answered by AI

Could you provide an overview of the investigations involving Pembrolizumab that have been conducted thus far?
