New study prepares those with genetic clot risk for future trials

NCT ID NCT07584265

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study enrolls 100 adults who have or may have Factor V Leiden or Prothrombin G20210A mutations, which increase the risk of blood clots. Participants undergo genetic testing to confirm their status, then attend a site visit for basic health checks like blood pressure, ECG, and blood tests. The goal is to establish a health baseline and familiarize participants with the clinical trial environment, so they can join future studies. The study lasts about 10 weeks and includes 1-2 visits and a follow-up call.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help prepare participants for future clinical trials aimed at preventing blood clots in people with these genetic mutations.
What could go wrong
This is an early engagement study, not a treatment trial. It does not test any new therapy, so there is no direct health benefit for participants.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Male or female participants aged ≥ 18 years at the date of signing the Participant Information Sheet/Informed Consent Form (PIS/ICF). 2. Ability to provide written, personally signed, and dated informed consent in accordance with International Council for Harmonisation (ICH) Good Clinical Practice (GCP) Guidelines E6 (R3) (2025) and applicable regulations, before any study-specific procedures are performed. 3. Confirmed or suspected diagnosis of FVL or Prothrombin G20210A mutation via targeted genetic testing. Exclusion Criteria: 1. Unwilling or unable to comply with the protocol-defined study assessments. 2. Any other significant disease or disorder that, in the opinion of the Principal Investigator (PI) or Sponsor, may either place the participant at risk from participation, or influence the clinical baseline.
