HRD Tests for Ovarian cancER (HERO)

September 16, 2025 updated by: Centre Francois Baclesse

The study concerns patients with Invasive epithelial ovarian cancer, primary Fallopian tube carcinoma, ovarian-type peritoneal carcinoma, and with an indication of a first-line platinum-based chemotherapy.

To determine HRD status, 2 separate tests will be performed in the study:

  1. Giscar assay : developed by the sponsor
  2. myChoice assay

If one or two tests identifies a HRD status :

a PARP inhibitor treatment may be initiated according to current recommendations

  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patient aged 18-year or more
  • Histologically documented high grade serous epithelial ovarian cancer, fallopian tube or peritoneum cancer
  • Newly diagnosed advanced (International Federation of Gynecology and Obstetrics [FIGO] stage III or IV) ovarian carcinoma, candidate to a first line platinum-based chemotherapy

  • Tumor tissue must be available for HRD analyses (FFPE tissue block) and

    • Collected if possible during the initial surgery or the initial biopsy (before chemotherapy)
    • With sufficient tumour surface area (> 25 mm²), with a final cellularity of at least 20%
  • Patient affiliated to an appropriate social security system
  • Patient signed consent form before any trial related activities

Exclusion Criteria:

  • Recurrent high grade serous epithelial ovarian cancer, fallopian tube or peritoneum cancer
  • Non epithelial or borderline ovarian cancer
  • Other tumor, for which the treatment may interfere with the ovarian cancer treatment and/or that may have a major impact on prognosis
  • Exclusive palliative setting
  • Patient deprived of liberty or placed under the authority of a tutor

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: HRD tests
To determine HRD status on the tumor, 2 different tests will be used concomitantly
Genetic: tests to determine HRD status

Test Giscar AND test myChoice will be performed.

If one or two tests identifies a HRD status :

a PARP inhibitor treatment may be initiated according to current recommendations

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Rate of platinum-sensitive ovarian cancer patients according to GIScar HRD signature (classified into HRD or HRP).
Time Frame: six months after the end of platinum-based chemotherapy
Evaluate Platinum-sensitivity patients (defined as absence of disease progression, according to RECIST 1.1 criteria, six months after a first-line platinum-based chemotherapy) correlated with Homologous Recombination status in tumor (HRD : Homologous Recombination deficient / HRP :Homologous Recombination Proficient)
six months after the end of platinum-based chemotherapy
