Colorectal cancer (CRC) remains a major public health problem in the United States and worldwide. The majority of patients who have CRC eventually present with metastatic disease. The overall therapeutic goals for most patients with metastatic CRC (mCRC) are to control the disease, prolong life span, and maximize quality of life. Therefore, the ratio of efficacy to toxicity is one of the most important factors in choosing among treatment options and sequencing regimens. In addition, the choice of first-line systemic therapy will affect the options for second-line treatment...

Colorectal cancer is one of the most frequent solid tumors in the western world, with low survival rates in patients with metastatic disease. Doublet chemotherapy regimens such as FOLFOX or FOLFIRI are the mainstay of standard first-line chemotherapy in the metastatic setting. The conventional treatment as a first-line approach is continuous application until progression or intolerable toxicities. However, only one third of patients are treated until progression mainly due to the side effects of chemotherapy...

PURPOSE: Diabetic macular edema is the leading cause of blindness in young adults in developed countries. Beyond metabolic control, several therapies have been studied such as laser treatment and intravitreal injections of corticosteroids or anti-vascular endothelial growth factor drugs. In terms of public health the long-term treatment with the current available drugs is very expensive and new therapies with the same or better effect should be investigated. This study sought to evaluate the efficacy and safety of intravitreal injections of ziv-aflibercept for the treatment of diabetic macular edema...

INTRODUCTION: Colorectal cancer is the third most common cancer worldwide. The prognosis of colorectal cancer patients still remains dismal and half of them will develop metastatic disease. Angiogenesis plays an essential role in colorectal tumorigenesis, and the VEGF pathway is one of the targets that has been validated up to now. The use of antiangiogenics along with chemotherapy has become an accepted standard for colorectal cancer. AREAS COVERED: This review discusses the efficacy and safety profile of ramucirumab, a fully human immunoglobulin G1 monoclonal antibody against the vascular endothelial growth factor receptor-2 (VEGFR-2), for the treatment of second-line metastatic colorectal cancer upon progression to first-line chemotherapy including anti-angiogenics...

Polypoidal choroidal vasculopathy (PCV) is an exudative maculopathy usually treated using photodynamic therapy (PDT) and antivascular endothelial growth factor agents. However, these cases may sometimes be refractory to both PDT and ranibizumab or bevacizumab, and may have persistent intra-retinal fluid. Recently, studies have reported that aflibercept may be effective in such resistant cases. However, high cost and limited availability has restricted its use to only a few countries. Ziv-aflibercept (Zaltrap), a systemic analogue of aflibercept, has been tried recently and it has been effective in macular oedema...

BACKGROUND: Aflibercept (ziv-aflibercept) is an anti-angiogenic agent recently approved in combination with FOLFIRI for the treatment of metastatic colorectal cancer (mCRC) patients previously treated with oxaliplatin. Despite heterogeneity in response to aflibercept, no biomarkers for efficacy or adverse effects have been identified. Here we present biomarker data from the randomised phase II AFFIRM trial assessing aflibercept in combination with mFOLFOX6 first line in mCRC. METHODS: Ninety-six somatic mutations in key oncogenic drivers of mCRC and 133 common single-nucleotide polymorphisms (SNPs) in vascular endothelial growth factor (VEGF) pathway genes were analysed, and 27 plasma markers measured at baseline, during and after treatment...

England's Cancer Drugs Fund will reduce the number of indications it pays for by nearly 30%. Projections suggested that the cost of the fund would have more than doubled by the end of the year, and the cuts will save £80 million ($121 million) by eliminating drugs such as eribulin and ziv-aflibercept.
