Evaluation of See.d as an Automated Blood Sample Preparator for Multiple Liquid Biopsy Applications
Study Details
Study Description
Brief Summary
This study aims to evaluate the feasibility of using See.d instrument and SBS slides for preparation of plasma and cytological samples from whole blood.
Forty-five participants will be enrolled (20 healthy volunteers and 25 metastatic breast cancer patients) and each participant will be asked to provide a blood sample.

Detailed Description
The goal of this study is the evaluation of a new instrument called See.d, to be used in conjunction with its accessories, Smart Bio Surface (SBS) slides, for preparation of cytological samples (seeded on SBS slides) and plasma from fresh whole blood (within 4-6 hours from collection).
Blood samples collected from healthy volunteers will be spiked-in with reference DNA and mock-CTC to mimic a patient sample in order to evaluate the instrument performance through the analysis of several parameters.
Blood samples from Metastatic Breast Cancer (MBC) patients will be processed with See.d instrument installed in a clinical context to perform a preliminary analytical characterization of either cell-free DNA (cfDNA) and Circulating Tumor Cells (CTC).
For its feasibility nature, no formal statistics has been planned for this study.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Healthy donors Participants who are in good health and without history of cancer disease |
|
| Metastatic Breast Cancer patients Metastatic breast cancer category is based on the definition of the European Society of Medical Oncology and is defined as disease spread to other parts of the body, such as bones, liver or lungs (also called stage IV). Tumours at distant sites are called metastases. |
