Axitinib made a 23% response rate and median duration of response of 17.five months. Median PFS was 7.4 months and median OS was 13.six months . Within the current phase III trial in patients with advanced RCC , axitinib 5 mg BID demonstrated superior PFS compared with sorafenib 400 mg BID using a considerably greater response rate . Patient-reported QoL was comparable among the two treatment arms. Toxicity profile of new antiangiogenic agents for mRCC Usually reported toxicities for antiangiogenic agents in individuals high throughput chemical screening with mRCC consist of class effects of fatigue, asthenia, diarrhea, nausea, anorexia, rash, HFS, and hypertension . Other toxicities or combinations of unwanted effects seem to be comparatively precise to particular antiangiogenic agents. Toxicities across cancer populations Toxicity profiles of antiangiogenic therapies lack illness specificity and therefore can be usefully summarized and compared across illness indications. AEs reported for these agents in individuals with mRCC are very equivalent to toxicities reported for sunitinib in gastrointestinal stromal tumors , sorafenib in hepatocellular carcinoma , bevacizumab monotherapy in glioblastoma, and bevacizumab plus chemotherapy for metastatic colorectal cancer, non-squamous non?small cell lung cancer, and metastatic breast cancer.
VEGF inhibitors Standard AEs in individuals with RCC receiving bevacizumab/ INF-? contain pyrexia, anorexia, fatigue, asthenia, bleeding, Linifanib hypertension, and proteinuria . Bevacizumab can also be associated with elevated incidence of potentially lifethreatening gastrointestinal perforations and thrombovascular events . A meta-analysis of 12,294 patients with a selection of solid tumors treated with bevacizumab in 17 randomized controlled trials reported that the addition of bevacizumab to other cancer therapy elevated the danger of gastrointestinal perforation by 1.6- to 5.7-fold, based on tumor form and dose . In addition, a current metaanalysis of >10,000 patients with cancer treated with bevacizumab revealed elevated incidence of treatmentrelated mortality, specifically in individuals who were also receiving taxanes or platinum agents. In phase III trials of bevacizumab plus INF-?, congestive heart failure and cardiac ischemia/infarction were reported . Specific effects of TKIs frequently incorporate hypertension, HFS , rash, mucositis, hypothyroidism, and myelosuppression . Across oncology trials with sunitinib, toxicities occurring in ?20% of individuals integrated anemia, diarrhea, fatigue, nausea, asthenia, mucositis/stomatitis, vomiting, hypertension, HFS, and rash . Sunitinib is also related to myelosuppression, elevated levels of thyroid-stimulating hormone , hypothyroidism, and hepatotoxicity which includes liver failure.
