The Adverse Effects and Use of Bevacizumab in Patients with Glioblastoma: A Systematic Review and Meta-Analysis. (PubMed, Pharmaceuticals (Basel)) - "BV is the active ingredient in the drugs Avastin®, Alymsys®, Mvasi® and ZiraBev®. Finally, the most common adverse effects were nausea, vomiting, fatigue and hypertension. While the beneficial properties of this pharmacological therapy have been observed, its adverse effect profile requires constant evaluation, as it includes vascular, blood and symptomatic adverse effects, which must be analyzed on a case-by-case basis and with great attention, especially in the case of more serious complications such as thromboembolic events."

Cost-efficiency and expanded access modeling of conversion to biosimilar bevacizumab in metastatic colorectal and non-squamous non-small cell lung cancer in Medicare. (PubMed, J Med Econ) - "The objective of this study is to explore the cost-efficiency and budget-neutral expanded access of bevacizumab-bvzr in mCRC and mNSCLC in Medicare.Methods We developed a Medicare payer perspective simulation model of patients treated for mCRC and mNSCLC to estimate cost-savings from converting bevacizumab (originator) to bevacizumab-bvzr or alternative biosimilars such as bevacizumab-awwb, -maly, and -abcd...At 100% conversion, monthly savings from biosimilar conversion could fund up to 13,887 additional mCRC patient-months of treatment with bevacizumab-bvzr + FOLFOX, and up to 8,959 additional mNSCLC patient-months of treatment with bevacizumab-bvzr + paclitaxel + carboplatin...The biosimilar NNC from other biosimilars ranged from 60-4,564 and 55-4,422 for mCRC and NSCLC, respectively.Conclusion In the first cost-efficiency and expanded access study of biosimilar bevacizumab in mCRC and mNSCLC, we find that bevacizumab-bvzr-based regimens can result in substantial cost..."

Cost-Efficiency Modeling of Conversion to Biosimilar Bevacizumab-bvzr in Metastatic Non-Small Cell Lung Cancer in Medicare (IASLC-WCLC 2024) - "Conclusions : In the first cost-efficiency and expanded access study of biosimilar bevacizumab in mNSCLC, we find that bevacizumab-bvzr + paclitaxel + carboplatin can result in substantial cost savings relative to originator-based first line treatment of patients with non-squamous mNSCLC in Medicare. These cost savings could be reinvested to treat a substantial number of additional patients with mNSCLC, or fund other costs of care in Medicare, on a budget-neutral basis."

Industry perspective on regulatory authority (RA) quality reviews of biosimilar applications - an evaluation of RA guidance and expectations for chemical, manufacturing, and controls information through in-depth query analysis. (PubMed, Expert Opin Biol Ther) - "Numbers/types of queries received following regulatory submissions (FDA/EMA, n = 7/n = 5) for seven biosimilars (PF-filgrastim [Nivestym], PF-rituximab [Ruxience®], PF-trastuzumab [Trazimera®], PF-bevacizumab [Zirabev®], PF-pegfilgrastim [Nyvepria®], PF-adalimumab [Abrilada™/Amsparity®], PF-infliximab [Ixifi]) from a single product portfolio were analyzed considering published regulatory authority (RA) guidance and in relation to sections/subsections of Module 3: Quality from the Common Technical Document regulatory dossier and topics based on keyword assignment. Topic assignments included: Control (12-27%/12-28%), Manufacturing (56-72%/34-66%), Stability (1-12%/2-24%), Biosimilarity (5-16%/5-25%), and Container Closure (0-3%/0-9%). The focus of both RAs on topics related to manufacturing and controls is valuable in understanding expectations for scientific and technical content related to gaining biosimilar approval."

Findings call for large, longitudinal studies to examine causality of certain AEs with rituximab-pvvr and bevacizumab biosimilars."

Use of Bevacizumab Originator versus Biosimilar Drugs for Oncology Indications in a Real-World Data Sample (HOPA 2023) - "This large real-world analysis showed that bevacizumab biosimilar use for on- and off-label indications increased substantially over time. Mvasi, although approved in April 2017, was not launched until July 2019, and Zirabev was unavailable until December 2019, accounting for low biosimilar use in 2019 and early 2020. Decreases in the originator drug and biosimilar drug use dropped in late 2020, which may be attributed to the COVID-19 pandemic."

Ocular Safety and Toxicokinetics of Bevacizumab-bvzr (Zirabev), a Bevacizumab Biosimilar, Administered to Cynomolgus Monkeys by Intravitreal Injection. (PubMed, J Ocul Pharmacol Ther) - "Bevacizumab-bvzr-related trace pigment or cells in vitreous humor (in 4 of 12 animals; commonly associated with IVT injection) and transient, nonadverse, mild ocular inflammation (in 1 of 12 animals) were noted upon ophthalmic examination and fully reversed during the recovery phase. Bevacizumab-bvzr was well tolerated via biweekly IVT administration in healthy monkeys, with an ocular safety profile comparable to saline or its vehicle control."
