Details and patient eligibility

About

The main objective of this pilot study is to investigate the protein / peptide plasma profiles before and after treatment with a direct anti-Xa (activated Factor 10) in patients with non-valvular atrial fibrillation to better understand the mechanisms of action of these molecules and perform exploratory analyses concerning proteins whose concentrations change after starting treatment.

Enrollment: 5 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Trial design

5 participants in 1 patient group

the Study Population

Description:

The study population consists of patients in the cardiology department at the Nîmes University Hospital with non-valvular atrial fibrillation and who are candidates for treatment with a direct oral anticoagulant: Rivaroxaban (Xarelto®). Patients will be selected according to criteria designed to result in a homogeneous population (associated anticoagulants, etc., see below). For this study, patients must not have had a direct oral anti-Xa (activated Factor 10) in the 6 months preceding enrollment. Intervention: Rivaroxaban

Treatment:

Drug: Rivaroxaban
