ABSTRACT

BACKGROUND AND OBJECTIVE: Aflibercept; a decoy receptor for vascular endothelial growth factors (VEGFs) and placental growth factor (PLGF), in combination with FOLFIRI (leucovorin calcium, fluorouracil, irinotecan hydrochloride) chemotherapy regime, was FDA approved in 2012 as second-line salvage chemotherapy for metastatic colorectal cancer (mCRC). This is the first systematic review, and meta-analysis-based evidence to determine the efficacy and safety of Aflibercept plus FOLFIRI regimen pooling randomized controlled trials and single-arm studies.

METHOD: PubMed, Cochrane library, Embase, and Clinical trial.gov were systematically searched for published randomized controlled trials, single-arm studies, and national patient programs on aflibercept plus FOLFIRI chemotherapy for the treatment of mCRC till 11/10/2022.

RESULT: Ten studies met the inclusion criteria comprising 1075 patients for efficacy studies and 2027 patients for safety studies. The pooled prevalences were 18% (95% CI, 5%-37%, p = 0.00) for 12m PFS and 61% (95% CI, 53% - 68%, p = 0.00) for 12m OS. The pooled prevalences were 69% (95% CI, 55% - 82%, p = 0.00) for any grade 3-4 toxicities, 10% (95% CI, 5% - 16%, p = 0.00) for grade 3-4 diarrhea, 13% (95% CI, 5% - 24%, p = 0.00) for grade 3-4 hypertension, 31% (95% CI, 22% - 40%, p = 0.00) for grade 3-4 neutropenia and 5% (95% CI, 2% - 7%, p = 0.00) for grade 3-4 venous thromboembolic event.

CONCLUSION: Our meta-analysis shows that the aflibercept plus FOLFIRI combination shows better survival efficacies however; it is also associated with more high-grade adverse events.

Evaluation of Patient Characteristics Linked to Major Bleeding Events in Patients Prescribed Direct Oral Anticoagulants

Clin Appl Thromb Hemost. 2023 Jan-Dec;29:10760296231172765. doi: 10.1177/10760296231172765.

ABSTRACT

INTRODUCTION: Direct oral anticoagulants (DOACs) demonstrated similar efficacy and lower risk of intracranial hemorrhage than warfarin in patients with atrial fibrillation and venous thromboembolism. Given the lack of data identifying risk factors in patients who bled while on a DOAC, we sought to investigate these characteristics.

MATERIALS AND METHODS: This retrospective chart review was approved by the Mass General Brigham Institutional Review Board and assessed patients who experienced bleeding events while on DOAC therapy from 6/1/2015 to 7/1/2020. Patient characteristics were evaluated, including age, sex, body mass index (BMI), renal function, concomitant therapies, and baseline comorbidities.

RESULTS: Eighty-seven patients were included for analysis, with a median age of 75.8 years. Most patients were female (51.7%) and 24 (27.6%) had a BMI >30. At time-of-event, 21 patients (24.1%) had acute kidney injury. Thirty-three patients (37.9%) were on concomitant antiplatelet therapy (APT), with 31 (35.6%) on single APT and 2 on dual APT. Pertinent comorbidities included hypertension (74.7%), ischemic cerebrovascular accident (28.7%), thyroid abnormality (23.0%), active cancer (14.9%), and anemia (13.8%). Eleven patients (12.6%) had a prior bleeding event. Most patients were on apixaban (69.0%) for the indication of stroke prevention in nonvalvular atrial fibrillation/flutter (72.4%). FDA-approved dosing was used in most patients (92.0%), and all deviations reflected underdosing. Most bleeding events were defined as major (95.4%), occurred at a critical organ site (72.4%), and developed spontaneously (58.6%).

CONCLUSIONS: These data provide insight into characteristics of patients who experience bleeding events while on DOAC therapy. Understanding these potential risk factors may optimize the safe use of these agents.

Safety Profile and Effectiveness of Rivaroxaban for Patients With Venous Thromboembolism in Japan　- Results From Post-Marketing Surveillance (XASSENT)

Circ J. 2023 May 27. doi: 10.1253/circj.CJ-23-0104. Online ahead of print.

ABSTRACT

BACKGROUND: The incidence of venous thromboembolism (VTE; pulmonary embolism [PE] and/or deep vein thrombosis [DVT]) in Japan is increasing, but relatively small numbers of patients from Japan have been included in studies investigating rivaroxaban (a direct factor Xa inhibitor) for the treatment of VTE and preventing its recurrence.Methods and Results: An open-label, prospective, observational study (XASSENT [NCT02558465]) investigated the safety profile and effectiveness of rivaroxaban for ≤2 years in the treatment of VTE and prevention of its recurrence in Japanese clinical practice. Primary outcomes were major bleeding and symptomatic recurrent VTE. Statistical analyses were exploratory and descriptive. Overall, 2,540 patients were enrolled (safety analysis population [SAP], n=2,387; effectiveness analysis population [EAP], n=2,386). In the SAP, >80% of patients received the approved rivaroxaban dose, the mean (standard deviation) age was 66.6 (15.0) years, ≈74% were >50 kg, and 43% had a creatinine clearance ≥80 mL/min. PE+DVT, PE only, and DVT only were reported in 42%, 8%, and 50% of patients, respectively, and active cancer in 17% of patients. Major bleeding was reported in 69 patients (2.89%; 3.60%/patient-year; SAP) and symptomatic PE/DVT recurrence in 26 patients (1.09%; 1.36%/patient-year; EAP) during the treatment period.

CONCLUSIONS: XASSENT provided information on the expected proportions of bleeding and VTE recurrence during rivaroxaban treatment in Japanese clinical practice; no new concerns of safety or effectiveness were found.

Venous thromboembolism secondary to hospitalization for COVID-19: patient management and long-term outcomes

Res Pract Thromb Haemost. 2023 May;7(4):100167. doi: 10.1016/j.rpth.2023.100167. Epub 2023 Apr 26.

ABSTRACT

BACKGROUND: Venous thromboembolism (VTE) is a complication of COVID-19 in hospitalized patients. Little information is available on long-term outcomes of VTE in this population.

OBJECTIVES: We aimed to compare the characteristics, management strategies, and long-term clinical outcomes between patients with COVID-19-associated VTE and patients with VTE provoked by hospitalization for other acute medical illnesses.

METHODS: This is an observational cohort study, with a prospective cohort of 278 patients with COVID-19-associated VTE enrolled between 2020 and 2021 and a comparison cohort of 300 patients without COVID-19 enrolled in the ongoing START2-Register between 2018 and 2020. Exclusion criteria included age <18<3

RESULTS: Patients with VTE secondary to COVID-19 had more frequent pulmonary embolism without deep vein thrombosis than controls (83.1% vs 46.2%, P<.001),P<.001),P<.001).P= 0.9) and the proportion of patients who discontinued anticoagulation (78.0% and 75.0%, P= 0.4) were similar between the 2 groups. Thrombotic event rates after discontinuation were 1.5 and 2.6 per 100 patient-years, respectively (P = 0.4).

CONCLUSION: The risk of recurrent thrombotic events in patients with COVID-19-associated VTE is low and similar to the risk observed in patients with VTE secondary to hospitalization for other medical diseases.
