Anticoagulant-associated bleeding: real-world data-driven pharmacovigilance and insights for bleeding management

Article

Author: Li, Liu-Cheng ; Wei, Qun ; Mao, Kai-Li ; Hong, Xia ; Wang, Zi-Lian ; Wang, Yu-Zhen

Background::

Anticoagulant drugs are essential for managing thrombotic diseases but lead to increasing bleeding risk. The choice of suitable anticoagulant drugs requires an assessment of the patient’s thrombotic risk factors and underlying ischemic pathology.

Methods::

This study constructs a closed-loop framework integrating qualitative literature review and quantitative data analysis to evaluate bleeding risks in anticoagulant therapy. The qualitative review covers molecular mechanisms, risk factors, and nursing practices related to anticoagulant drugs. Quantitatively, we analyzed the bleeding events from the FDA Adverse Event Reporting System (FAERS) database (2004–2024), using disproportionality analysis with Reporting Odds Ratio, Proportional Reporting Ratio, Bayesian Confidence Propagation Neural Network, and Empirical Bayes Geometric Mean to identify significant bleeding signals. For each anticoagulant drug, the 10 strongest signals were extracted and anatomically profiled to construct a drug-specific hemorrhage atlas. Logistic regression analyses were applied to investigate the effects of age, sex, reporter, and comorbidities on the occurrence of anticoagulant drugs-associated bleeding. To address the critical issue of bleeding risk management in the clinic, we further discussed the multidisciplinary nursing across the anticoagulation therapy cycle.

Results::

The study revealed significant variations in bleeding risks among different anticoagulants. Anticoagulant-associated bleeding comprised 110 701 reports from FAERS database. Elderly patients (≥65 years old) supplied 63.2% of cases; 32% of events emerged within 30 days of therapy initiation. Hospitalization was documented in 46.8% and death in 20.7%. Spinal subdural hemorrhage yielded the highest signal (ROR 144.79, 95% CI 28.09–746.33), followed by adrenal, mesenteric, and intracranial hemorrhages among all anticoagulant drugs. Gastric/lower gastrointestinal bleeding appeared in the top-10 list of every oral anticoagulant, while retroperitoneal bleeding was a shared high-signal event among heparins and parenteral direct thrombin inhibitors. Betrixaban exhibited extreme RORs for traumatic (ROR 18 059.67, 95% Cl: 8829.21–36 940.05) and intracranial (ROR 643.97, 95% Cl: 249.82–1660) bleeding. Each drug also exhibited distinct bleeding characteristics and differences in organ system distribution. Multivariable logistic regression across four hierarchical models identified agents with distinct, model-independent bleeding risk profiles relative to warfarin.

Conclusions::

This large-scale pharmacovigilance study provides the most comprehensive, publicly available atlas of anticoagulant-related bleeding signals. The pronounced inter-drug heterogeneity and persistent long-term risk mandate individualized choice of agent and prolonged monitoring to ultimately improve the safety–efficacy balance of antithrombotic therapy.

Clinical laboratory testing of blood from patients presenting to the emergency department with acute bleeding due to factor Xa inhibitors: An unmet medical need

Review

Author: Peacock, W Franklin ; Wu, Alan H B

Bleeding is a life-threatening side effect of oral anticoagulants and can be a medical emergency. For patients on warfarin, stat testing of blood for the prothrombin time and calculation of the International Ratio (PT-INR) are used to determine if acute bleeding is caused by excess anticoagulation. Direct acting oral anticoagulants (DOACs) include those that inhibit Factor Xa (apixaban, rivaroxaban, edoxaban, and betrixaban) or Factor IIa (dabagatran). Unlike warfarin, there are no recommendations for regular monitoring of DOAC drug levels. Testing is useful for bleeding patients if a reversal agent is being considered. In addition, the use of thrombolytic therapy is contraindicated for the treatment of an ischemic stroke for a patient on a DOAC. However, current laboratory assays for anti-Factor Xa are calibrated for the specific DOAC used and results are not typically available in emergency departments. Therefore, there is a need to produce a rapid bedside blood test that can detect bleeding to any DOAC drug that was prescribed.

Intracranial Hemorrhage With Direct Oral Anticoagulants vs Low-Molecular-Weight Heparin in Brain Tumors

Review

Author: Fuse, Kenshiro ; Rhee, John Y. ; Goulart, Thiago Oscar ; Wang, Chen ; Zambrano, Daniela ; Bukhari, Yasir

BACKGROUND AND OBJECTIVES:

Patients with brain tumors face an increased risk of arterial and venous thromboembolic events. However, owing to risk of intracranial hemorrhage (ICH), clinician practice patterns vary on preference for anticoagulation treatment. This meta-analysis evaluates the safety of direct oral anticoagulants (DOACs) vs low-molecular-weight heparin (LMWH) on the development of ICH in patients with brain tumor.

METHODS:

We searched MEDLINE, Embase, Web of Science, and Cochrane Central Register of Controlled Trials (January 2010-June 2025) for randomized-controlled trials or cohort studies enrolling adults (age ≥18 years) with primary or metastatic brain tumors receiving therapeutic DOACs (apixaban, rivaroxaban, edoxaban, betrixaban, and dabigatran) vs LMWH (enoxaparin, dalteparin, nadroparin, and tinzaparin). Studies limited to prophylactic dosing or non-brain tumor patients were excluded. Pooled risk ratios (RRs) with 95% CIs were calculated using a restricted random-effects model. Heterogeneity (I²) and bias were evaluated, with prespecified subgroups (tumor type, follow-up duration, and study quality) and sensitivity analyses. The study protocol was registered on PROSPERO (CRD42025635334).

RESULTS:

Among 762 publications identified, 10 retrospective cohort studies (1,572 patients: 645 DOAC, 895 LMWH) were included. Patients' mean or median age ranged 60.4-67 years (DOAC) vs 53-64 years (LMWH), with follow-up durations ranging from 3 to 12 months. Patients with primary or metastatic brain tumors receiving DOACs had a statistically significantly lower risk of any ICH compared with LMWH (RR = 0.50, 95% CI 0.29-0.87; p = 0.01, I² = 49.50%). Reduction was more pronounced in 3 studies with three-month follow-up (RR = 0.23, 95% CI 0.09-0.57; p < 0.01, I² < 0.01%). Stratified analyses showed reduced ICH risk with DOACs in primary brain tumors (5 studies, RR = 0.20, 95% CI 0.08-0.54; p < 0.01, I² < 0.01%) but not in metastatic brain tumors (5 studies, RR = 0.86, 95% CI 0.44-1.68; p = 0.66, I² = 36.04%). Leave-one-out analyses confirmed robustness, and cumulative meta-analysis demonstrated stable estimates with narrowing CIs. Egger (p = 0.19) and Begg (p = 0.59) tests showed no statistical evidence of publication bias.

DISCUSSION:

In the current meta-analysis, DOACs were associated with significantly lower ICH risk than LMWH in patients with anticoagulated brain tumor, particularly those with primary brain tumors. Findings support DOACs as a safe anticoagulant in arterial and venous thromboembolism. Given observational designs with inherent confounding, findings warrant cautious interpretation.

Tr1X, Inc. Announces $75 Million Series A Financing to Develop Best-in-Class Universal Allogeneic Regulatory T (Treg) and CAR-Treg Cell Therapies to Treat and Potentially Cure Autoimmune and Inflammatory Diseases

SAN DIEGO, CA, USA I January 17, 2024 I Tr1X, Inc. today announced its emergence from stealth with a $75 million Series A financing to bring universal allogeneic regulatory T (Treg) and CAR-Treg cell therapies to the clinic to treat and potentially cure autoimmune and inflammatory diseases. The financing was led by Bay Area-based The Column Group, with participation from NEVA SGR and Alexandria Ventures. The Company appointed William Lis Chief Executive Officer, strengthened its leadership team with other biopharma industry veterans, and announced members of the Board of Directors and Scientific Advisory Board. "We are thrilled to partner with Bill Lis, Maria Grazia Roncarolo and Tr1X's world-class team to revolutionize the field through its innovative, breakthrough science," said Leon Chen, Ph.D., MBA, Partner at The Column Group and Tr1X Board Member. "With its experienced management team at the helm, we are confident in Tr1X's ability to bring curative cell therapies to patients who currently require life-long treatment and management." Science and Pipeline The Company's science is primarily based on the work of Tr1X's Scientific Founder Maria Grazia Roncarolo, M.D., the discoverer of Type 1 regulatory T (Tr1) cells, which have features that can benefit patients with autoimmune and inflammatory diseases. Tr1 cells, a differentiated subpopulation of regulatory T cells, are crucial for maintaining homeostasis and tolerance in healthy individuals and have several important functions. These include dampening of local inflammation and downregulation of the inflammasome, suppression of pathogenic effector T cell responses, and induction of long-term tolerance as observed in preclinical models and patients. Tr1X's proprietary technology enables the conversion of CD4 + T cells isolated from healthy donors into Treg-like cells that have a similar function and profile to naturally occurring Tr1 cells. These cells can be further engineered to target specific tissues or organs to enable local, targeted immunomodulation. With a proprietary, GMP-grade, closed-loop system that provides consistency, quality and reliability at scale, Tr1X can enable production of its products at commercial volume. Currently, Tr1X is working on its first investigational Tr1 cell therapy, TRX103, which it plans to evaluate in a Phase 1 trial to prevent Graft versus Host Disease (GvHD) in patients undergoing mismatched hematopoietic stem cell transplant. The Company is developing additional pipeline programs to treat inflammatory bowel disease, Type 1 diabetes and multiple B-cell mediated autoimmune diseases. "The ability to develop a pipeline of medicines based on our work on regulatory T cells represents the culmination of decades of discovery and research into the underpinnings of immunological tolerance and autoimmunity," said Dr. Roncarolo, Scientific Founder, President and Head of R&D at Tr1X. "Tr1 cells have unique properties and represent the ideal therapeutic platform from which to develop 'immune reset' products. Our two platforms have the required attributes to address a broad set of indications, including dual targeting of pathogenic T and B cells. These engineered cells have the potential to induce tolerance, which could transform the lives of people living with chronic autoimmune diseases by providing them with a cure instead of ongoing treatment." Proven Leadership Team, Board of Directors and Scientific Advisory Board Tr1X is led by industry veterans with cell therapy expertise who have a track record of discovery, development and commercialization of more than a dozen novel first- or best-in-class medicines.

What are factor Xa inhibitors and how do you quickly get the latest development progress?

Factor Xa inhibitors are a class of anticoagulant drugs that work by inhibiting Factor Xa, a key enzyme in the coagulation cascade. The development of Factor Xa inhibitors began in the early 1980s, with the first inhibitor, antistasin, being isolated from the salivary glands of the Mexican leech Haementeria officinalis in 1987. Four drugs from this class are currently marketed worldwide. Rivaroxaban (Xarelto) was the first approved Factor Xa inhibitor, becoming commercially available in Europe and Canada in 2008. This was followed by the approval of apixaban (Eliquis) in Europe in 2011 and in the United States in 2012. Edoxaban (Lixiana, Savaysa) was approved in Japan in 2011 and in Europe and the US in 2015. The most recent addition to this class is betrixaban (Bevyxxa), which was approved in the US in 2017¹ Looking ahead, Factor Xa inhibitors are expected to continue to play a significant role in anticoagulant therapy. They are just as efficacious as low molecular weight heparin (LMWH) and warfarin but are given orally and don't need as strict monitoring. However, the emergence of resistance and the lack of an effective reversal drug when bleeding occurs are challenges that need to be addressed. Ongoing research and development efforts are focused on addressing these issues and expanding the clinical applications of Factor Xa inhibitors The analysis of target factor Xa in the pharmaceutical industry reveals a competitive landscape with multiple companies focusing on its development. Pfizer Inc., Bristol Myers Squibb Co., AstraZeneca PLC, Daiichi Sankyo Co., Ltd., and Bayer AG are among the companies growing the fastest under this target. The indications for drugs targeting factor Xa cover a wide range of cardiovascular and thrombotic conditions, indicating their potential in treating these diseases. Small molecule drugs, chemical drugs, and recombinant coagulation factors are progressing rapidly under this target. The European Union, the United States, and Japan are leading in terms of drug development, but China has also shown progress. Further analysis is required to understand the specific progress in China and its impact on the future development of target factor Xa. Overall, target factor Xa presents a promising opportunity in the pharmaceutical industry with a diverse range of companies, indications, drug types, and countries/locations involved in its development. The mechanism of action of factor Xa inhibitorsFactor Xa inhibitors are a type of medication that specifically target and inhibit the activity of factor Xa, which is a key enzyme involved in the blood clotting process. From a biomedical perspective, factor Xa is a crucial component of the coagulation cascade, a series of reactions that leads to the formation of blood clots. By inhibiting factor Xa, these medications prevent the formation of blood clots and reduce the risk of conditions such as deep vein thrombosis, pulmonary embolism, and stroke. Factor Xa inhibitors work by binding to factor Xa and blocking its ability to activate other clotting factors, ultimately preventing the formation of a stable blood clot. This mechanism of action makes them anticoagulant drugs, meaning they help to prevent the excessive formation of blood clots. These inhibitors are commonly used in the treatment and prevention of thromboembolic disorders, such as atrial fibrillation, venous thromboembolism, and post-operative prophylaxis. Examples of factor Xa inhibitors include rivaroxaban, apixaban, and edoxaban. It's important to note that factor Xa inhibitors carry a risk of bleeding, as they interfere with the normal clotting process. Therefore, their use should be carefully monitored, and patients may require regular blood tests to assess their coagulation status. Additionally, factor Xa inhibitors should be used with caution in individuals with certain medical conditions or those taking other medications that increase the risk of bleeding.
