Официальное название
Breast Cancer Subtype Characterization Through Patient's Derived Organoids". (BCinsightPDO)
Обзор
Development of tools to predict patients chemo-sensitivity and identification of corresponding biomarkers is an urgent challenge for BC patients lacking targeted therapies, such as TNBC, or for patients experiencing relapse after adjuvant chemotherapy or targeted therapies. The refinement of 3D-cultivation techniques, experienced in the last decade, has allowed cultivation of patients-derived cancer cells in organotypic structures, named patient-derived organoids (PDO), which preserve histologic, genomic and transcriptomic features of primary tumors. PDO allow propagation, pharmacological treatment and genetic manipulation of patients-derived cancer cells in a close to physiology setting, thus representing a promising tool in the development of personalized therapies
Подробное описание
PDO have been shown to efficiently recapitulate ex-vivo the in vivo response to hormonal treatment of BC patients. These observations point to PDO as potential valuable tools for a rapid, personalized prospective evaluation of patient-specific chemo-sensitivity. Moreover, PDO can represent a valuable ex-vivo platform for screening new treatments, or combination of current treatments, in a medium-to-high-throughput fashion. Thus, development of a stable collection of PDO representing the heterogeneity of BC subtypes, including the evolution of recurrent disease, represents an extremely useful resource for both prospective and retrospective studies aimed at understanding the molecular phenotype associated with chemoresistance.
Первичные конечные точки
- evaluate the histological and molecular conformity (yes/no) between PDO and matched primary and/or recurrent BC sample, in order to develop a live biobank of ER/PR+, HER2+ and TNBC PDO. [Срок оценки: 36 months]
- evaluate the sensitivity of ER/PR+, HER2+ and TNBC PDO to novel therapeutic agents in clinical trials for BC or other cancer types [Срок оценки: 42 months]
Вторичные конечные точки (2)
- test the sensitivity of PDO to splicing-targeting treatments, either alone or in combination with other therapies [Срок оценки: 42 months]
- test the synergizing effects of agents splicing-targeting treatments to immunotherapies by co-culture experiments with autologous immune cells [Срок оценки: 42 months]
