NCT05905939

Brief Summary

Planned study population consists of approximately 1,000 adult patients with HER2-positive mBC receiving anti-HER2 therapy in about 50 oncological centers (in each center it is expected to recruit about 20 patients) in different regions in order to provide representative study sample. Patients will be included consecutively from the least recent diagnosis (within defined time period). Planned retrospective follow-up period for 1 patient is a period starting from the date of mBC diagnosis until end study or until patient's death, whichever occurs first. End of study will be at least 12 months after the latest date of mBC diagnosis to ensure all patients have the opportunity to contribute at least 12 months of data.

Study Population

This non-interventional multicenter observational study will include 1,000 adult patients with HER2-positive mBC receiving anti-HER2 therapy (except for trastuzumab deruxtecan). Patients will be included in about 50 oncological centers (in each center it is expected to recruit about 20 patients) in various regions of Russian Federation

You may qualify if:

  • The diagnosis of mBC was established between the 1st July 2021 and the 1st July 2022;
  • Patients with the availability of at least 12 months of follow-up data (from the index data) in the medical records at the participating site, unless patient died within the first 12 months of diagnosis;

You may not qualify if:

  • Presence of other malignancies within period since diagnosis until the timepoint of data collection;
  • Patients receiving trastuzumab deruxtecan currently or in the anamnesis;
  • The participation in any randomized controlled trial within period since diagnosis until end of study.
