  • Subjects who give a written informed consent obtained according to local guidelines.

Who cannot join

  • Subjects with muscle-invasive (i.e. T2, T3, T4), locally advanced unresectable, or metastatic urothelial carcinoma as assessed on baseline radiographic imaging obtained within 90 days prior to study registration. The required radiographic imaging includes:
  • Abdomen/Pelvis - CT scan
  • Chest - chest x-ray or CT scan
  • Subjects with concurrent upper urinary tract (i.e. ureter, renal pelvis) urothelial carcinoma of any stage.

About this study

Official title: A Phase II Trial for the Use of Intravesical Gemcitabine and Docetaxel (GEMDOCE) in the Treatment of BCG naïve Non-muscle Invasive Urothelial Carcinoma of the Bladder

A single-arm, two-stage, open-label, phase 2 study investigating the safety and efficacy of intravesical gemcitabine/docetaxel for bacillus Calmette-Guerin (BCG)-naïve patients with non-muscle invasive bladder cancer (NMIBC).

Read the detailed description

All participants will receive an induction course of gemcitabine/docetaxel instillations (administered once a week for six consecutive weeks) followed by monthly maintenance instillations if initial efficacy is seen. In addition to providing initial efficacy data, this study will provide safety and long-term efficacy data on the combination regimen studied. A tolerable safety profile and demonstrated efficacy would support a potential, randomized phase 3 trial comparing the experimental combination therapy and standard of care intravesical BCG therapy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • GemcitabineDrug

    Also called Gemzar

    1g gemcitabine in 50ml sterile water; instilled once weekly for 6 weeks and then once monthly for ≤ 21 months.

  • DocetaxelDrug

    Also called Taxotere

    37.5mg docetaxel in 50ml normal saline solution (NSS); instilled once weekly for 6 weeks and then once monthly for ≤ 21 months.

Study groups in NCT04386746
Study groupRoleWhat they receive
Intravesical Gemcitabine/DocetaxelExperimentalGemcitabine/Docetaxel induction is given intravesically in sequential order once a week for six consecutive weeks. One gram of gemcitabine in 50 ml of sterile water is slowly instilled into the bladder via a Foley catheter and the catheter is clamped for 60 minutes. The bladder is then drained and 40 mg of docetaxel in 50 ml of NSS is then slowly instilled via the Foley catheter into the bladder. The catheter is again clamped for 60 minutes before draining. If initial efficacy seen, patients will have monthly maintenance instillations of Gemcitabine/Docetaxel.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Gemcitabine and Docetaxel in people with Urothelial Carcinoma Bladder and Bladder Cancer, run by Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins 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 21 inclusion and 11 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 17 Nov 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 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 Sep 2023). 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?

3-Month Complete Response Rate (time frame: 3 months). 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 17 Nov 2025.
