Erivedge (vismodegib) was approved by the FDA to treat adult patients with basal cell carcinoma, the most common type of skin cancer. The drug is intended for use in patients with locally advanced basal cell cancer who are not candidates for surgery or radiation and for patients whose cancer has spread to other parts of the body (metastatic).
The drug is the first FDA-approved drug for metastatic basal cell carcinoma. It received expedited review under the FDAs priority review program. The safety and effectiveness of Erivedge was evaluated in a single, multi-center clinical study in 96 patients with locally advanced or metastatic basal cell carcinoma. Of the patients with metastatic disease receiving Erivedge, 30 percent experienced a partial response and 43 percent of patients with locally advanced disease experienced a complete or partial response.
Basal cell carcinoma is generally a slow growing and painless form of skin cancer that starts in the top layer of the skin (epidermis). The cancer develops on areas of skin that are regularly exposed to sunlight or other ultraviolet radiation.
Erivedge is a pill taken once a day and works by inhibiting the Hedgehog pathway, a pathway that is active in most basal cell cancers and only a few normal tissues, such as hair follicles.
The most common side effects observed in patients treated with Erivedge were muscle spasms, hair loss, weight loss, nausea, diarrhea, fatigue, distorted sense of taste, decreased appetite, constipation, vomiting, and loss of taste function in the tongue.
Erivedge is being approved with a boxed warning alerting patients and health care professionals of the potential risk of death or severe birth defects to a fetus (an unborn baby). Pregnancy status must be verified prior to the start of Erivedge treatment. Male and female patients should be warned about these risks and the need for birth control.
Erivedge is marketed by South San Francisco based-Genentech, a member of the Roche Group.
