Monitoring and dosing guidance for anticoagulants in pulmonary embolism patients

The Study of Monitoring and Dosing Guidance of Direct Oral Anticoagulants Based on Pharmacokinetics, Pharmacodynamics, and Pharmacogenomics

Observational Peking Union Medical College Hospital · NCT06362343

This study is testing a new way to monitor and adjust blood-thinning medication for people with pulmonary embolism to see if it can improve their treatment outcomes.

What this trial studies

This study aims to develop a population pharmacokinetic-pharmacodynamic (PK-PD) model for Direct Oral Anticoagulants (DOACs) in patients with pulmonary embolism. It will investigate the factors influencing the PK-PD of DOACs, including the correlation between genetic characteristics and clinical outcomes. The study will also explore the relationship between drug concentrations, coagulation indices, and clinical outcomes to establish effective monitoring and dosing strategies for DOACs.

Who should consider this trial

Good fit: Ideal candidates are adult patients diagnosed with acute symptomatic pulmonary embolism who are eligible for Xa factor inhibitors and have completed the acute phase of anticoagulation.

Not a fit: Patients with severe liver dysfunction, severe renal impairment, or contraindications for Xa factor inhibitors may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to personalized anticoagulant dosing, improving treatment outcomes for patients with pulmonary embolism.

How similar studies have performed: Other studies have shown promise in using pharmacogenomics and PK-PD modeling for anticoagulant therapy, suggesting potential success for this approach.
