Abelacimab for thrombosis (e.g. atrial fibrillation-related stroke prevention and venous thromboembolism) as of January 2026

This page presents a standardized, committee-reviewed assessment of the reimbursement risk associated with Abelacimab for thrombosis (e.g. atrial fibrillation-related stroke prevention and venous thromboembolism) as of January 2026, calibrated against historical HTA and payer outcomes across the US, EU4, UK, and Japan using a structured 10-domain evaluation framework.

Updates & Coverage Scope

MARA Ratings reflect the evidence and payer context available as of the stated date. Where material new evidence or payer decisions emerge, MARA may issue a rating action under the Rating Actions & Surveillance Policy.

What the Complimentary MARA Rating Includes

The Full MARA Assessment provides full 10-domain scoring, weighted determinants, benchmarking against comparable assets, and historical context calibrated to observed HTA outcomes.

Reimbursement Risk Positioning

This assessment positions the asset relative to reimbursement thresholds observed across major HTA bodies. It distinguishes structural drivers of reimbursement risk from variables that are typically sensitive to evidence maturity or price expectations.

The Full MARA Assessment provides weighted scoring across all 10 domains and benchmarks this positioning against historical reimbursement outcomes for comparable evidence profiles.

Selected Risk Drivers

Below is a snapshot of domains that materially influence the MARA Rating. The Full MARA Assessment provides complete 10-domain scoring and the evidence-linked rationale for each domain outcome.

Clinical effectiveness

Abelacimab has shown promising efficacy in preventing venous thromboembolism (VTE) in a Phase 2 trial, significantly outperforming enoxaparin. However, its efficacy in preventing strokes in atrial fibrillation (AF) is still unproven, as the relevant Phase 3 trials are ongoing. The lack of definitive data on stroke prevention limits the overall assessment of clinical effectiveness.

Cost effectiveness

Economic evaluations indicate that Abelacimab is likely to be cost-saving and more effective compared to rivaroxaban, with significant savings attributed to reduced bleeding complications. The model suggests it remains cost-effective even at higher price points, reinforcing its economic value.

Quality of life

There is currently no direct patient-reported outcome data available for Abelacimab. While the potential for improved quality of life is inferred from its reduced bleeding risk and convenient dosing schedule, the absence of validated HRQoL measures means the evidence is weak.

The Full MARA Reimbursement Risk Assessment expands this analysis with weighted scoring, benchmarking depth, and ranking versus hundreds of comparable assets.

Benchmarking & Historical Calibration

This asset is benchmarked against therapeutic-area comparators and a historical dataset of previously assessed products. MARA calibrates rating bands against observed reimbursement outcomes across major HTA bodies.

Scope of the Full MARA Assessment

Designed to support governance and diligence before major commitments in pricing, evidence generation, partnering, or launch planning.
