Plain-language summary
Background:
The study aims to address the challenge of accurately identifying patients with ovarian cancer who would benefit from poly-ADP ribose inhibitors (PARPi) as first-line maintenance therapy. While BRCA1/2-mutated epithelial ovarian cancer (EOC) patients have shown significant benefits from PARPi treatment, the efficacy in homologous recombination deficient (HRD) patients remains inconclusive. Current assays used to estimate HR status do not effectively differentiate between patients who benefit most from PARPi and those who do not, making it inefficient to treat all patients. There is a need for a more accurate HR status testing method to optimize PARPi benefit. This study aims to assess the performance of the VHIO-CARD-300 test in determining HR status compared to SOPHiA DDMâ„¢ Dx HRD Solution.
Summary:
The study is a prospective, non-randomized trial designed to evaluate the concordance of the VHIO-CARD-300 test in establishing HR status compared to SOPHiA DDMâ„¢ Dx HRD Solution. Additionally, it aims to assess the association between HRD status determined by the VHIO-CARD-300 test and treatment efficacy. Patients with advanced FIGO stage III-IV high grade serous or endometrioid ovarian, fallopian tube, or peritoneal cancer will be invited to participate. Those eligible will undergo testing with both VHIO-CARD-300 and SOPHiA DDMâ„¢ Dx HRD Solution. Patients classified as HRD positive will receive olaparib in combination with bevacizumab, while others will receive bevacizumab alone. Treatment will be administered according to approved doses, with follow-up evaluations conducted until RECIST progression.

Inclusion criteria
✓. Patient with newly diagnosed high- grade serous or endometrioid Ovarian cancer, primary peritoneal cancer and/or fallopian-tube cancer. I-3-3 At an advanced stage: FIGO stage IIIB, IIIC, or IV of the 1988 FIGO classification (see appendix 1).
✓. Patient who has completed prior to enrollment first line platinum-taxane chemotherapy:
✓. Platinum-taxane based regimen must have consisted of
✓. minimum of 6 treatment cycles and a maximum of 8. However, if platinum-based therapy must be discontinued early as a result of non-hematological toxicityspecificallyrelated to the platinum regimen, (i.e. neurotoxicity, hypersensitivity etc.), patient must have received a minimum of 4 cycles of the platinum regimen.
✓. Patient must have received prior to enrollment a minimum of 3 cycles of bevacizumab in combination with the 3 last cycles of platinum-based chemotherapy. Only in case of interval debulking surgery, it is allowed to realize only 2 cycles of bevacizumab in combination with the last 3 cycles of platinum-based chemotherapy.
✓. Patient must be prior to enrollment without evidence of disease (NED) or in complete response (CR) or partial response (PR) from the first line treatment. There should be no clinical evidence of disease progression (physical exam, imagery, CA 125) throughout he first line treatment and prior to study enrollment.

Timeframe: Through study completion, an average of 1.5 years
. Patient must be randomized at least 4 weeks and no more than 8 weeks after her last dose of chemotherapy (last dose is the day of the last infusion) and all major toxicities from theprevious chemotherapy must have resolved to CTCAE grade 1 or better (except alopecia and peripheral neuropathy).
✓. Patient must have normal organ and bone marrow function:
