Vismodegib is a novel, small-molecule inhibitor of smoothened, a key component of the hedgehog signaling pathway. Increased hedgehog pathway signaling is critical in the development of hereditary and spontaneous basal cell carcinomas of the skin, and has been implicated in the development of a number of other tumors. ⋯ Clinically, phase I and II studies showed dramatic anticancer activity in patients with advanced basal cell carcinomas. In January 2012, vismodegib was approved by the FDA for the treatment of unresectable or metastatic basal cell carcinomas of the skin.

Gout is a metabolic disorder of excess uric acid accumulation that manifests clinically as inflammatory arthritis, chronic arthropathy and the formation of deposits of uric acid known as tophi. A primary objective of gout management is to reduce the excess urate burden by regular use of drugs that reduce serum urate levels. Conventional urate-lowering drugs available in the U. ⋯ In recent clinical trials, pegloticase normalized plasma urate levels, reduced the size of tophi, and improved functional status and quality of life in patients with refractory disease. Immunogenicity to pegloticase is associated with loss of urate-lowering response and the risk of infusion reactions. Pegloticase is effective in treating hyperuricemia and the clinical manifestations of gout in patients who cannot be adequately managed with conventional therapy.
