Trial summary

Previous studies show that the majority NMIBC patients experience side effects to BCG and therefore terminate the instillations before completing all planned instillations. This will increase their risk of recurrence and potential cystectomy. Read more about this study

About this study

Official title: Nordic Urothelial Cancer Research Group Study on Reduced BCG Dwell-Time in High Risk NMIBC

Previous studies show that the majority NMIBC patients experience side effects to BCG and therefore terminate the instillations before completing all planned instillations. This will increase their risk of recurrence and potential cystectomy. The purpose of this study is to investigate if NMIBC patients who experience severe side effects to BCG instillations will experience fewer or less severe side effects if reducing dwell-time of BCG instillations.

The study will include patients from Denmark, Iceland, Norway and Sweden.

Read the detailed description

Approximately 8,000 patients are diagnosed with bladder cancer (BC) in the Nordic countries every year. The majority of BC patients are diagnosed with non-muscle invasive bladder cancer (NMIBC). The majority of NMIBC are treated with Bacillus Calmette-Guérin vaccine (BCG) as adjuvant treatment but for carcinoma in situ it is the primary treatment. BCG is known to give a lot of side effects both local and systemic, the severity of these can lead to premature termination of the treatment.

The object of this PhD project is to investigate if reduced dwell time, the time the BCG is in the bladder, will decrease the severity of side effects due to BCG instillations.

This will be investigated in a Nordic setting and the project will be done as a two-armed randomized clinical trial.

By decreasing the severity of side effects, we hypothesize the number of patients completing all planned instillations will increase and thereby decrease the risk of the BC evolving into a more aggressive type.

Being tested
Bacillus Calmette Guerin

What participants receive

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

  • Bacillus Calmette GuerinDrug

    The same dose of the drug will be given in both arms but the dwell-time will be adjusted for the subjects in the intervention arm according to the grading of side effects given by the study algorithm.

Study groups in NCT04701151
Study groupRoleWhat they receive
InterventionExperimentalStudy Subjects randomized to the interventional arm will be assigned to BCG induction therapy once-weekly for 6 weeks and subsequent 1 year of maintenance (6+3x3) of which dwell-time during the first of the 6 induction instillations is 2 hours. If side effects are registered before the second and all further instillations, Study Subject in the intervention arm will be reduced in dwell-time according to the grading of side effects as given by the study algorithm.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Bacillus Calmette Guerin in people with Side Effect of Drug, run by Jørgen Bjerggaard Jensen at 11 sites in 3 countries.

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 8 inclusion and 24 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 3 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in Denmark, Sweden, Iceland. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Completion of instillations (time frame: 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 3 Mar 2026.
