Bevacizumab may improve quality of life, but not overall survival in glioblastoma: an epidemiological study.

The vascular endothelial growth factor antibody bevacizumab (Avastin®), received approval for the treatment of recurrent glioblastoma in many countries including the US and Switzerland, but not the European Union, in 2009. Here we explored the hypothesis that the approval of bevacizumab improved outcome with glioblastoma on a population level.


Frequency of Bevacizumab and Ranibizumab Injections for Diabetic Macular Edema in Medicare Beneficiaries.

To describe the frequency and variation of intravitreal bevacizumab (Avastin; Genentech, South San Francisco, CA) and ranibizumab (Lucentis; Genentech, South San Francisco, CA) use for diabetic macular edema (DME) in the United States.

Congenital Hypertrophy of the Retinal Pigment Epithelium Presenting With Secondary Choroidal Neovascularization.

The authors report a case of a congenital hypertrophy of the retinal pigment epithelium (CHRPE) associated with choroidal neovascularization (CNV) causing symptomatic vision loss. Two intravitreal injections of bevacizumab (Avastin; Genentech, South San Francisco, CA) 4 weeks apart resolved the fluid and improved the visual acuity. This case demonstrates that CHRPE can rarely be complicated by CNV, which may respond to intravitreal bevacizumab therapy. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:276-277...


Anti-angiogenic treatment (Bevacizumab) improves the responsiveness of photodynamic therapy in colorectal cancer.

Photodynamic therapy (PDT) is a new treatment utilizing the combined action of photosensitizers and light for the treatment of various cancers. The mechanisms for tumor destruction after PDT include direct tumor cell kill by singlet oxygen species (OS), indirect cell kill via vascular damage, and an elicited immune response. However, it has been reported that many cellular activators, including vascular endothelial growth factor (VEGF), are produced by tumor cells after PDT. In this study, we demonstrate th...

Analytical and functional similarity of Amgen biosimilar ABP 215 to bevacizumab.

ABP 215 is a biosimilar product to bevacizumab. Bevacizumab acts by binding to vascular endothelial growth factor A, inhibiting endothelial cell proliferation and new blood vessel formation, thereby leading to tumor vasculature normalization. The ABP 215 analytical similarity assessment was designed to assess the structural and functional similarity of ABP 215 and bevacizumab sourced from both the United States (US) and the European Union (EU). Similarity assessment was also made between the US- and EU-sour...

In vitro models have demonstrated immune-modulating effects of bevacizumab. Combinations of EGFR tyrosine kinase inhibitor (TKI) with bevacizumab improve progression free survival (PFS) in patients with EGFR mutated lung adenocarcinoma. How bevacizumab confers this clinical effect and underlying mechanisms are not clear.

Bevacizumab rechallenge in glioblastoma patients with initial response to bevacizumab who later progress off therapy.

The Safety of Bevacizumab Administered Shortly after Laser Interstitial Thermal Therapy in Glioblastoma: A Case Series.

Laser interstitial thermal therapy (LITT) enables ablation of lesions using thermal energy with minimal damage to surrounding regions. Bevacizumab has been used as an adjuvant therapy in recurrent glioblastoma (GBM). Presently, administration of Bevacizumab occurs at least 4-6 weeks after surgical intervention. However, given the minimally invasive nature of LITT, we suggest that Bevacizumab can be safely used in combination with LITT at a shorter interval.

Assessment of the higher order structure of Humira®, Remicade®, Avastin®, Rituxan®, Herceptin®, and Enbrel® by 2D-NMR fingerprinting.

The advent of monoclonal antibody biosimilar products has stimulated the development of analytical methods that can better characterize an important quality attribute, namely the higher order structure (HOS). Here, we propose a simple approach based on heteronuclear 2D NMR techniques at natural abundance for generating spectral fingerprints of the HOS at high resolution. We show that the proposed method can assess the HOS of six therapeutic products, adalimumab (Humira®), bevacizumab (Avastin®), inflixima...

Anti-angiogenic effect of adiponectin in human primary microvascular and macrovascular endothelial cells.

Neovascularization in retina and choroid involves interplay of many cytokines and growth factors. Vascular endothelial growth factor (VEGF) being a pro-angiogenic molecule has been found to be high in aqueous and vitreous humour of patients with proliferative diabetic retinopathy (PDR). VEGF is also found in the fibroblast and retinal pigment epithelial cells (RPE) of choroidal neovascular (CNV) membranes isolated from patients. Though anti-VEGF agents cause regression of clinically visible new vessels, the...

Secondary structure assessment of formulated bevacizumab in the presence of SDS by deep ultraviolet resonance Raman (DUVRR) spectroscopy.

A deep-ultraviolet resonance Raman (DUVRR) spectroscopic method has been used to study the secondary structural changes of a therapeutic monoclonal antibody (mAb), bevacizumab (Avastin™) under a chemical stress: the presence of sodium dodecyl sulfate (SDS). The results demonstrate that DUVRR spectroscopy can assay the higher order structure of the formulated protein in a sensitive and selective manner. The SDS-induced partially unfolding of the mAb was probed by DUVRR spectroscopy where the amide I, II an...

The cost-effectiveness of bevacizumab, ranibizumab and aflibercept for the treatment of age-related macular degeneration-A cost-effectiveness analysis from a societal perspective.

The discussion on the use of bevacizumab is still ongoing and often doctors are deterred from using bevacizumab due to legal or political issues. Bevacizumab is an effective, safe and inexpensive treatment option for neovascular age-related macular degeneration (AMD), albeit unregistered for the disease. Therefore, in some countries ophthalmologists use the equally effective but expensive drugs ranibizumab and aflibercept. We describe the economic consequences of this dilemma surrounding AMD treatment from ...

Bevacizumab in Cervical Cancer: 5 Years After.

Over the past 5 years, addition of bevacizumab to combination chemotherapy for advanced, recurrent, and persistent cervical cancer has offered prolonged overall and progression-free survival. Since the original press release announcing the survival benefits of this antiangiogenesis therapy, there has been further study of bevacizumab related to quality of life, combination with other agents, use of imaging to evaluate likelihood of response, and development of biosimilars. This review summarizes publication...

Estimating Medicare and patient savings from the use of bevacizumab for the treatment of exudative age-related macular degeneration.

The Medicare cost savings from the use of bevacizumab in the United States for the treatment of exudative age-related macular degeneration (AMD) were estimated by replacing the use of bevacizumab with ranibizumab and aflibercept.

Cumulative dose of bevacizumab associates with albuminuria rather than podocyturia in cancer patients.

Angiogenesis inhibition with bevacizumab, a monoclonal antibody against vascular endothelial growth factor A (VEGF-A), is an anticancer treatment associated with hypertension and renal glomerular toxicity referred to as a preeclampsia-like syndrome. In preeclampsia, podocyturia predates proteinuria and clinical features of preeclampsia, and is regarded as a biomarker of ongoing glomerular injury. Using a quantitative polymerase chain reaction of the podocyte-specific molecules nephrin, podocin, and VEGF-A i...

Real world study of regimen containing bevacizumab as first-line therapy in Chinese patients with advanced non-small cell lung cancer.

Large scale randomized controlled trials have demonstrated that the use of bevacizumab in addition to chemotherapy in patients with advanced non-small cell lung cancer (NSCLC) conveys significant survival benefits. We explored the clinical impact of a first-line regimen containing bevacizumab (B+) versus a non-bevacizumab regimen (non-B) in advanced non-squamous NSCLC (NS-NSCLC) patients in a real world setting.

The clinical efficacy and safety of paclitaxel combined with avastin for NSCLC patients diagnosed with malignant pleural effusion.

The current study aimed to investigate the clinical efficacy of paclitaxel combined with avastin for non-small cell lung cancer (NSCLC) patients diagnosed with malignant pleural effusion (MPE).

Copy number load predicts outcome of metastatic colorectal cancer patients receiving bevacizumab combination therapy.

Increased copy number alterations (CNAs) indicative of chromosomal instability (CIN) have been associated with poor cancer outcome. Here, we study CNAs as potential biomarkers of bevacizumab (BVZ) response in metastatic colorectal cancer (mCRC). We cluster 409 mCRCs in three subclusters characterized by different degrees of CIN. Tumors belonging to intermediate-to-high instability clusters have improved outcome following chemotherapy plus BVZ versus chemotherapy alone. In contrast, low instability tumors, w...

Importance of vitrectomy in endophthalmitis : How immediate vitrectomy can restore visual acuity.

This article presents a case of endophthalmitis after intravitreal injection with bevacizumab (Avastin®) in a patient suffering from exudative age-related macular degeneration (AMD). Within 1h after diagnosis the patient underwent vitrectomy with intravitreal injection of antibiotics combined with corticosteroids and 4 weeks after the endophthalmitis the visual acuity increased to 0.5. This case report demonstrates that an immediate vitrectomy combining intravitreal injection of medication can lead to a...

Bevacizumab and Glioblastoma: Past, Present, and Future Directions.

Glioblastoma (GBM) is the most common and lethal intracranial malignancy, with few advances in treatment over the last several decades. Much excitement surrounded the initial approval for bevacizumab for recurrent GBM, given the marked radiographic responses and improvement in progression-free survival observed in early studies. However, phase III studies have failed to demonstrate an overall survival advantage with the use of this agent. An overview of the mechanism of action and activity of bevacizumab in...

Bevacizumab Monotherapy Reduces Radiation-induced Brain Necrosis in Nasopharyngeal Carcinoma Patients: A Randomized Controlled Trial.

Studies have shown that addition of bevacizumab to corticosteroids improves outcome against radiation-induced brain necrosis (RN). Here, we aimed to evaluate the effectiveness and safety of bevacizumab monotherapy on RN in nasopharyngeal carcinoma (NPC) patients.

Nanoparticles provide long-term stability of bevacizumab preserving its antiangiogenic activity.

Bevacizumab is one of the most common monoclonal antibodies used to treat cancer due to its antiangiogenic role. However, the frequent parenteral administrations are not attractive for the patient adhesion to the therapy. Nanoencapsulation of bevacizumab might be a useful alternative to increase administration intervals, due to controlled release properties. To achieve a long-term bevacizumab stability into PLGA nanoparticles, we developed an optimized and validated lyophilization protocol. The co-encapsula...
