Feasibility Study Aiming at Pre-Analytical Standardization of Whole Blood Processing for Liquid Biopsy Applications
An observational study of Healthy Participants, run by Tethis S.p.A. at 1 site in Italy.
Trial summary
The goal of this feasibility study is to evaluate a new sample preparator called See.d. After blood processing the instrument will produce a set of slides and a tube of plasma. These outputs could be used in further analysis in liquid biopsy applications. Read more about this study

About this study
The goal of this feasibility study is to evaluate a new sample preparator called See.d.
After blood processing the instrument will produce a set of slides and a tube of plasma. These outputs could be used in further analysis in liquid biopsy applications.
Read the detailed description
This feasibility study aims at the evaluation of a new instrument called See.d , to be used in conjunction with its accessories, Smart Bio Surface (SBS) slides and reagents, for preparation of cytological samples (seeded on SBS slides) and plasma from fresh whole blood (within 4-6 hours from collection).
Blood samples will be collected from healthy volunteers and will be used to test See.d performances. Moreover the possibility of develop a new version of the instrument with increased processing capability and to develop and optimize analytical protocols for liquid biopsy applications will be evaluated as exploratory objectives.
The only study procedure will be the collection of a blood sample from each participants; during this study 200 participants will be enrolled.
For its feasibility nature, no formal statistics has been planned for this study.

Questions about this trial
What is this clinical trial studying?
An observational study of Healthy Participants, run by Tethis S.p.A. at 1 site in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 12 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Luca Santoleri (02 2643 2340, MEDICI.CDS@HSR.IT), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
SBS slides stability (time frame: 1 day (at the blood draw)). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05942066, which also lists 10 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Feb 2026.
