JAVEMACS: Japan AVElumab Maintenance And Continuous Treatment Study

August 7, 2026 updated by: Merck Healthcare KGaA, Darmstadt, Germany, an affiliate of Merck KGaA, Darmstadt, Germany

A Multicenter, Retrospective, Observational Study of Avelumab Maintenance and Subsequent Therapies in Japanese Patients With Locally Advanced or Metastatic Urothelial Carcinoma

This study is a multicenter, non-interventional, retrospective, medical chart review of locally advanced or metastatic (la/m) Urothelial Cancer UC participants who were prescribed avelumab as first line maintenance therapy after a platinum-based chemotherapy. This study aims to understand the index date (i.e., at the initiation of avelumab maintenance therapy) demographics and clinical characteristics of participants with locally advanced/metastatic Urothelial Carcinoma in Japan, and to describe their treatment patterns and outcomes.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Time Frame: Baseline
To describe the baseline clinical and demographic characteristics of participants.
Baseline

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
