Abstract

Insights

Pooling data from European Precision Cancer Medicine (PCM) trials accelerates patient cohort completion. The PRIME-ROSE project demonstrates feasible data sharing for robust clinical trial advancements.

Area of Science:

  • Oncology
  • Clinical Trials
  • Data Science

Background:

  • Precision Cancer Medicine (PCM) trials face patient accrual challenges due to tumor heterogeneity.
  • Small patient cohorts limit the assessment of clinical benefit in individual studies.

Purpose of the Study:

  • To address patient accrual limitations in PCM trials by pooling data from multiple European studies.
  • To establish a framework for data sharing and aggregation in PCM research.

Main Methods:

  • The PRIME-ROSE project facilitates data merging by aligning study procedures and harmonizing data.
  • Utilizing the Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM) for data standardization and aggregation.
  • Establishing a multidisciplinary organization to navigate institutional and country-specific data governance requirements.

Main Results:

  • Aggregated data from European Drug Rediscovery Protocol (DRUP)-like trials enabled cohort completion.
  • The PRIME-ROSE project monitors over 300 cohorts across more than 20 treatments, involving over 1,000 patients.
  • Over 20 cohorts have progressed following interim analysis.

Conclusions:

  • Data sharing across European trials is feasible and significantly advances PCM studies.
  • The PRIME-ROSE project's methodologies provide a foundation for future data integration in PCM clinical trials.
  • This approach supports the viability of conducting robust PCM trials in a global context.
