What is being measured

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

  1. Occurrence of Urinary Tract Cancer

    Occurrence of urinary tract cancer, which include malignant neoplasm and carcinoma in situ of the urinary tract, is reported as incidence rates per 1000 patient years. Incidence rates were estimated using Poisson regression and computed as the number of outcome events divided by the total person-time-at-risk (in years), multiplied by 1,000 for easier comparison. The country-level datasets were analyzed separately. Thereafter, pooled incidence rates were estimated using the aggregated number of outcome events and time-at-risk of all study countries using the Poisson regression.

    Measured: From 181 days after index date until the occurrence of a censoring event or cancer outcome event. Up to 6 (Sweden/Finland) or 7 years (UK).

  2. Occurrence of Bladder Cancer

    Occurrence of bladder cancer, malignant and carcinoma in situ, is reported as incidence rates per 1000 patient years. Incidence rates were estimated using Poisson regression and computed as the number of outcome events divided by the total person-time-at-risk (in years), multiplied by 1,000 for easier comparison. The country-level datasets were analyzed separately. Thereafter, pooled incidence rates were estimated using the aggregated number of outcome events and time-at-risk of all study countries using the Poisson regression.

    Measured: From 181 days after index date until the occurrence of a censoring event or cancer outcome event. Up to 6 (Sweden/Finland) or 7 years (UK).

  3. Occurrence of Renal Cancer

    Occurrence of malignant renal cancer is reported as incidence rates per 1000 patient years. Incidence rates were estimated using Poisson regression and computed as the number of outcome events divided by the total person-time-at-risk (in years), multiplied by 1,000 for easier comparison. The country-level datasets were analyzed separately. Thereafter, pooled incidence rates were estimated using the aggregated number of outcome events and time-at-risk of all study countries using the Poisson regression.

    Measured: From 181 days after index date until the occurrence of a censoring event or cancer outcome event. Up to 6 (Sweden/Finland) or 7 years (UK).

Individual data sharing
No: Clinical studies sponsored by Boehringer Ingelheim, phases I to IV, interventional and non-interventional, are in scope for sharing of the raw clinical study data and clinical study documents. Exceptions might apply, e.g. studies in products where Boehringer Ingelheim is not the license holder; studies regarding pharmaceutical formulations and associated analytical methods, and studies pertinent to pharmacokinetics using human biomaterials; studies conducted in a single center or targeting rare diseases (in case of low number of patients and therefore limitations with anonymization).

Are results available for this study?

Yes. Results are posted in the registry (first posted 28 Mar 2025). 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?

Occurrence of Urinary Tract Cancer (time frame: From 181 days after index date until the occurrence of a censoring event or cancer outcome event. Up to 6 (Sweden/Finland) or 7 years (UK).). The study lists 3 primary outcomes in all. 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 20 Apr 2025.
