INSPIRE: A European training network to Foster research and training in cardiovascular safety pharmacology

Guns PD, et al. J Pharmacol Toxicol Methods 2020.

ABSTRACT

Safety pharmacology is an essential part of drug development aiming to identify, evaluate and investigate undesirable pharmacodynamic properties of a drug primarily prior to clinical trials. In particular, cardiovascular adverse drug reactions (ADR) have halted many drug development programs. Safety pharmacology has successfully implemented a screening strategy to detect cardiovascular liabilities, but there is room for further refinement. In this setting, we present the INSPIRE project, a European Training Network in safety pharmacology for Early Stage Researchers (ESRs), funded by the European Commission's H2020-MSCA-ITN programme. INSPIRE has recruited 15 ESR fellows that will conduct an individual PhD-research project for a period of 36 months. INSPIRE aims to be complementary to ongoing research initiatives. With this as a goal, an inventory of collaborative research initiatives in safety pharmacology was created and the ESR projects have been designed to be complementary to this roadmap. Overall, INSPIRE aims to improve cardiovascular safety evaluation, either by investigating technological innovations or by adding mechanistic insight in emerging safety concerns, as observed in the field of cardio-oncology. Finally, in addition to its hands-on research pillar, INSPIRE will organize a number of summer schools and workshops that will be open to the wider community as well. In summary, INSPIRE aims to foster both research and training in safety pharmacology and hopes to inspire the future generation of safety scientists.

Thrombotic Risk in Cancer Patients: Diagnosis and Management of Venous Thromboembolism

Citro R, et al. J Cardiovasc Echogr 2020 - Review.

ABSTRACT

Venous thromboembolism (VTE) represents a major health problem, especially in cancer patients, who experience a significantly higher incidence of both deep vein thrombosis and pulmonary embolism compared to the general population. Indeed, patients with cancer have a prothrombotic state resulting in both increased expression of procoagulants and suppression of fibrinolytic activity. In addition, VTE increases the morbidity and mortality of these patients. For all these reasons, the prevention and treatment of VTE in cancer setting represent major challenges in daily practice. In general, low-molecular-weight heparin monotherapy is the standard of care for the management of cancer-associated VTE, as Vitamin K antagonists are less effective in this setting. Direct oral anticoagulants offer a potentially promising treatment option for cancer patients with VTE, since recent studies demonstrated their efficacy and safety also in this peculiar setting.

Cardioprotective Strategies to Prevent Cancer Treatment-Related Cardiovascular Toxicity: a Review

Upshaw JN. Curr Oncol Rep 2020 - Review.

ABSTRACT

PURPOSE OF REVIEW: Patients with cancer have an elevated risk of cardiovascular disease. This review describes the cardiovascular risks of different cancer therapies and the evidence for cardioprotective strategies.

RECENT FINDINGS: Recent studies have provided additional support for the safety and efficacy of dexrazoxane and liposomal anthracycline formulations in certain high-risk patients receiving anthracyclines and for neurohormonal antagonist therapy in patients with breast cancer receiving sequential anthracyclines and trastuzumab. Ongoing studies are exploring the benefit of: (1) statins for anthracycline cardioprotection; (2) strict blood pressure control during vascular endothelial growth factor inhibitor treatment and; (3) dexrazoxane on long-term cardiac outcomes in pediatric populations. To date, there are no evidence-based cardioprotective strategies specifically for radiation-related heart and vascular disease, immunotherapy myocarditis, fluoropyrimidine cardiotoxicity, vascular endothelial growth factor inhibitor-related hypertension, BCR-Abl multikinase inhibitor vascular disease, and other established and emerging cancer therapeutics with cardiovascular effects. Current evidence supports specific cardioprotective strategies for high risk patients receiving anthracyclines or sequential anthracycline-trastuzumab therapy; however, major evidence gaps exist.

Risk factors for pediatric cerebral sinovenous thrombosis: A case-control study with case validation

Sellers A, et al. Thromb Res 2020.

ABSTRACT

INTRODUCTION: Cerebral sinovenous thrombosis (CSVT) represents the second most common type of venous thromboembolism (VTE) in children. Current literature includes limited evidence on risk factors for CSVT, particularly in the pediatric population. We sought to determine risk factors for CSVT in pediatric patients through a single-institutional case-control study. In addition, we evaluated thrombophilias, treatments and outcomes in CSVT among cases.

METHODS: A case-control study was performed at Johns Hopkins All Children's Hospital on patients admitted from March 31, 2006 through April 1, 2018. Cases were identified using diagnostic codes and confirmed based on electronic health record (EHR) and neuroimaging review. Controls were matched in a 2:1 fashion accounting for the month and year of admission.

RESULTS: A total of 60 CSVT cases and 120 controls were identified. Median (range) age was 4.8 years (0-21.3 years) for cases and 5.6 years (0-20.0 years) for controls. Factors putatively associated with CSVT in unadjusted analyses were: corticosteroid use, presence of a central venous catheter, mechanical ventilation, systemic infection, head/neck infection, head/neck trauma, and chronic inflammatory disease. In the multivariable model, head/neck infection (OR: 13.8, 95% CI: 4.87-38.7; P < 0.01), head/neck trauma (OR: 12.7, 95% CI: 2.88-56.2; P < 0.01), and mechanical ventilation (OR: 9.32, 95% CI: 2.35-36.9; P = 0.01) remained independent, statistically-significant risk factors. 61% of patients were subacutely treated with anticoagulants and of those, only two developed relevant bleeding after initiation of therapy.

CONCLUSIONS: This single-institutional case-control study reveals that head/neck infection, head/neck trauma, and mechanical ventilation are independent risk factors for pediatric CSVT. These findings will be further investigated via a cooperative registry of pediatric hospital-acquired VTE, by which a risk model for pediatric CSVT will be developed and validated, in order to inform future preventive strategies in at-risk pediatric patients.
