简要总结

The project focuses on developing new experimental models of ovarian cancer that accurately reflect patients who do not respond to first-line platinum-based treatments and who are resistant to PARP inhibitors (PARPi). These models are essential for testing new drugs or drug combinations in preclinical settings that closely mimic real clinical conditions. These models will also help to identify predictive biomarkers of treatment response and to better understand the biological mechanisms behind therapy resistance.

详细描述

The aims of the present project are:

  • to generate new experimental models from biopsies of ovarian cancer patients whose tumors are either refractory to platinum-based therapy or have relapsed during or after treatment with platinum and PARPi;
  • molecularly, and pharmacologically characterize these models, including patient-derived xenografts (PDXs) grown in immunodeficient animals, organoids (3D in vitro models) and primary cell cultures (2D) derived from the same biopsies;
  • to use these models to identify new biomarkers of therapy response, study resistance mechanisms, and design preclinical trials for new therapeutic strategies; The study involves transplanting fresh tumor tissue into immunodeficient mice to create PDX models, as well as generating organoids and cell cultures. It will run for 10 years and include adult female patients (aged 18 or older) with recurrent ovarian cancer treated at the European Institute of Oncology, who have given informed consent. Clinical and pathological data will be collected at enrollment and during follow-up and stored in a coded database.

结局指标

主要结局

To obtain new in vivo experimental models of ovarian carcinomas

时间窗: 10 years

To obtain new experimental models from biopsies of ovarian carcinomas that are refractory to platinum-based therapy and recurrent during or after treatment with platinum-based therapy and PARP inhibitors, as treated at the Division of Medical Gynecologic Oncology of the European Institute of Oncology. To this end, a portion of the neoplastic tissue will be transplanted subcutaneously into at least two immunodeficient mice and follwed for tumor appearance

To obtain new in vitro experimental models of ovarian carcinomas

时间窗: 10 years

To obtain new experimental models from biopsies of ovarian carcinomas that are refractory to platinum-based therapy and recurrent during or after treatment with platinum-based therapy and PARP inhibitors, as treated at the Division of Medical Gynecologic Oncology of the European Institute of Oncology. To this end, a portion of the neoplastic tissue will digest with collagesase and single cell suspension obtained and seeded with specific mediums suplemented with growth factors in vitro to obtain primary cultures and organoids

次要结局

  • Pharmacological characterization of the obtained models: in vivo outcomes(10 years)
  • Pharmacological characterization of the obtained models: in vitro outcomes(10 years)
  • Molecular identification of potential biomarker of response(10 years)
