Vemurafenib (trade name Zelboraf) is a low molecular weight, orally available kinase inhibitor. It inhibits of some mutated forms of BRAF serinethreonine kinase, including BRAF V600E and is indicated for the treatment of patients with unresectable or metastatic melanoma with BRAF V600E mutation as detected by an FDA-approved test. Vemurafenib also inhibits other kinases in vitro such as CRAF, ARAF, wild-type BRAF, SRMS, ACK1, MAP4K5 and FGR at similar concentrations. Vemurafenib is not recommended for use in patients with wild-type BRAF melanoma. Zelboraf does not cure melanoma, but stops it's progression. Some 26% of patients in clinical trials developed a non melanoma form of skin cancer called cutaneous squamous cell carcinoma, which can usually be removed via relatively simple surgery. Other side effects include joint pain, rash, hair loss, fatigue, nausea, and skin sensitivity to sunlight. Patients taking Zelboraf must avoid sun exposure. It's not yet clear how long Zelboraf can increase melanoma survival.

Sample Use Guides

In Vivo Use Guide

960 mg twice daily. Administer ZELBORAF approximately 12 hours apart with or without a meal. Management of symptomatic adverse drug reactions may require dose reduction, treatment interruption, or treatment discontinuation of ZELBORAF. Dose reductions resulting in a dose below 480 mg twice daily are not recommended

Route of Administration: Oral

In Vitro Use Guide

The antitumor effects of vemurafenib against SM1 cells were tested by in vitro MTS cell proliferation assay after 72 hours of treatment. The IC50 of vemurafenib was 14 uM, which is approximately one log higher than the sensitivity of M229 (IC50 of 0.5 uM), a BRAF V600E mutant human melanoma cell line highly sensitive to vemurafenib, and at a similar range as the relatively resistant BRAF V600E mutant human melanoma cell line M233 (IC50 of 15 uM).
