About this study

Official title: A Phase I/II Trial for the Use of Intravesical Cabazitaxel, Gemcitabine, and Cisplatin (CGC) in the Treatment of BCG-Refractory Non-muscle Invasive Urothelial Carcinoma of the Bladder Cancer

The investigators intend to evaluate the safety and toxicity profile of intravesically administered multidrug regimen of Cabazitaxel, Cisplatin and Gemcitabine in treatment refractory Transitional Cell Carcinoma.The investigators propose to conduct a combined phase I trial to assess the safety, toxicity, and efficacy of a novel multidrug intravesical regimen consisting of Cabazitaxel, Gemcitabine, and Cisplatin (CGC) in the treatment of BCG resistant non-muscle invasive urothelial carcinoma of the bladder. This phase I trial will have a combined dose and cycle-escalation scheme with enrollment of up to 24 patients.

Read the detailed description

Nonsurgical treatment strategies for BCG refractory bladder cancer have failed to prove themselves as reliable options for increased survival among this subset of bladder cancer patients. For these patients, removal of the bladder with all the associated perioperative risks and the subsequent reduction of quality of life, remains the only option. Prior attempts at second line treatments have included intravesical (within the bladder) monotherapy with a range of drugs including Gemcitabine and Paclitaxel (a taxane, similar to Cabazitaxel). These drugs have shown some potential improvement for a small number of patients Given the synergy of systemic chemotherapy, it is believed that a multidrug regimen would allow for further improvement in survival among these patients.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Phase 1a/1b: The number of serious adverse events associated with therapy of intravesically administered Cabazitaxel, Gemcitabine, and Cisplatin.

    The investigator is measuring safety by looking at the number of events that occur during the study

    Measured: 6 weeks from baseline

  2. Phase 2: The number of complete responders after completion of six weeks of intravesically

    The investigator is measuring efficacy by the number of complete responders to the treatment

    Measured: 6 weeks from baseline

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Cabazitaxel, Gemcitabine and Cisplatin in people with Urothelial Carcinoma of the Urinary Bladder, run by Guarionex J. Decastro 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 16 inclusion and 16 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: under way, not looking for participants, as of the sponsor's last update on 24 Feb 2025. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

This study is still under way. Results are not available in the source record yet.

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?

Phase 1a/1b: The number of serious adverse events associated with therapy of intravesically administered Cabazitaxel, Gemcitabine, and Cisplatin. (time frame: 6 weeks from baseline). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02202772.

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 24 Feb 2025.
