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...


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...

Laparoscopic repair of bevacizumab-induced vesicovaginal fistula in metastatic colon cancer - a video vignette.

Bevacizumab is a humanized monoclonal antibody targeting vascular endothelial growth factor (VEGF). Adding bevacizumab to a variety of first-line regimens used for metastatic colon cancer improves outcomes. Vesicovaginal fistula (VVF) is an extremely rare complication of bevacizumab, which has been reported in a few patients with metastatic cervical cancer. Here, we report a patient with metastatic colon cancer who developed VVF after bevacizumab treatment and which was successfully repaired using a laparo...


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

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...

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.

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...

Bevacizumab in age-related macular degeneration: a randomized controlled trial on the effect of on-demand therapy every 4 or 8 weeks.

Intravitreal anti-vascular endothelial growth factor (VEGF) injections are an effective treatment for neovascular age-related macular degeneration (nARMD). Bevacizumab appears to be a cost-effective off-label anti-VEGF alternative to ranibizumab, but an optimal injection schedule has not yet been determined. In this study, we investigate whether on-demand bevacizumab treatment every 8 weeks is non-inferior to on-demand bevacizumab every 4 weeks in treating nARMD.

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 ...

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...

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...

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.

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...

Dynamic Angiogenic Switch as Predictor of Response to Chemotherapy-Bevacizumab in Patients With Metastatic Colorectal Cancer.

Previous studies have shown that metastatic colorectal carcinoma (mCRC) patients treated with bevacizumab, experience variation in the plasma levels of angiogenesis growth factors and related cytokines, called angiogenic switch (AS). The aim of the present study was to analyze the relationship between AS and the clinical response during standard chemotherapy-bevacizumab treatment.

Switch maintenance therapy with docetaxel and bevacizumab after induction therapy with cisplatin, pemetrexed, and bevacizumab in advanced non-squamous non-small cell lung cancer: a phase II study.

Switch maintenance therapy, using alternative agents that were not administered during induction chemotherapy, is a treatment option for advanced non-squamous non-small cell lung cancer (NSCLC). Bevacizumab is known to increase the efficacy of other chemotherapeutic agents; however, switch maintenance therapy with docetaxel and bevacizumab has not been adequately studied. The goal of this study was to evaluate the efficacy and safety of switch maintenance therapy with docetaxel and bevacizumab following ind...

A Trial-Based Cost-Effectiveness Analysis of Bevacizumab and Chemotherapy versus Chemotherapy Alone for Advanced Nonsquamous Non-Small-Cell Lung Cancer in China.

The first-line bevacizumab plus chemotherapy resulted in a clinical efficacy for Chinese patients with advanced nonsquamous non-small-cell lung cancer (NSCLC). Some economic analyses have carried out various methods to evaluate the cost-effectiveness of bevacizumab as the first-line treatment for NSCLC in other countries. Our objective was to assess the cost-effectiveness of bevacizumab plus chemotherapy compared with chemotherapy alone for the first-line treatment of advanced nonsquamous NSCLC.
