Study summary

This prospective non-interventional study is intended to generate new data and insights into first-line (1L) treatment of newly diagnosed advanced high-grade epithelial Ovarian cancer (OC) in Germany relevant for patients, physicians and payers. It will capture the influence of 1L Poly ADP ribose polymerase inhibitor (PARPi) maintenance treatment (MTX) on medical routine in Germany, especially on:

  • outcome of the 3-steps 1L treatment phase (including surgery, Chemotherapy (CTX) and MTX) including the potential of patients with primary advanced OC to be cured,
  • patient's follow-up (FU) during and after MTX therapy,
  • patient-reported outcomes (PROs), experiences and needs,
  • physician's experience,
  • BRCA/HRD and genomic scar testing behavior at diagnosis/during 1L therapy,
  • patient selection for different 1L systemic treatment approaches,
  • use and safety of drugs,
  • treatment sequence in case of recurrence

What researchers measure

Primary outcomes

  1. progression-free survival (PFS)

    The primary outcome is progression-free survival (PFS) defined as time from 1st dose of 1L platinum-based CTX to disease progression (investigator-assessed according to clinical routine) or death of any cause.

  4. Second progression-free survival (PFS2)

    Second progression-free survival (PFS2) is defined as time from 1st dose of 1L platinum-based CTX to second disease progression (investigator-assessed according to clinical routine) or death of any cause. Methods and intervals of tumor assessments are at the discretion of the treating physician and will be recorded in the eCRF

    Time frame: time from 1st dose of 1L platinum-based CTX to second disease progression (investigator-assessed according to clinical routine) or death of any cause, whichever came first, assessed up to 84 months
