NCT06981377

Brief Summary

The study aims to develop PRIME (PRostate cancer plasma Integrative Multi-modal Evaluation) liquid biopsy test and to implement its use to query prospectively collected samples in advanced prostate cancer (PCa) clinical trials and/or clinical settings. In order to maximise the utility of liquid biopsies for advanced PCa, PRIME is focused on the development of novel computational and sequencing approaches that integrate multiple information from plasma circulating elements: i) cell free DNA (cfDNA) gene mutation data with accurate quantitation of cfDNA structural genomic changes, ii) cfDNA genomic profiling with cfDNA methylation status, and iii) the information provided by extracellular vesicles (EVs) and EV-associated cargo (including DNA, RNA and proteins).

Study Arms (2)

Metastatic Castration Resistant Prostate Cancer (mCRPC) patients

This group includes mCRPC patients treated with serial lines of treatment. For each line of treatment, blood samples are collected: 1. Before starting the treatment; 2. After 12 weeks; 3. At the end of the treatment/progression.

Diagnostic Test: Analysis of cell free DNA, and extracellular vesicles (EVs) and EV-associated molecular components (including RNA, DNA, proteins)

Metastatic Hormon Sensitive Prostate Cancer (mHSPC) patients

This group includes mHSPC patients treated with hormone therapy. In the hormone sensitive setting, blood samples are collected: 1. Before starting the treatment; 2. After 12 weeks; 3. Every six months until progression to the castration resistant status.

Diagnostic Test: Analysis of cell free DNA, and extracellular vesicles (EVs) and EV-associated molecular components (including RNA, DNA, proteins)

Interventions

Plasma and buffy coat samples are shipped from the recruiting clinical sites to the lab of Professor Francesca Demichelis at the University of Trento (UniTN). At UniTN, samples are stored in dedicated freezers with restricted access and subsequently used as follows: * the plasma is used for the isolation of cell free DNA and extracellular vesicles (EVs); * the buffy coat is used for the extraction of genomic DNA. Nucleic acids sequencing library preparations and all downstream omics analyses are performed by Prof. Demichelis team.
