This is very interesting. I am unaware of any other such treatment for BCC. Although this is only for advanced tumours at this point, it does point towards new treatment options in the future.
The Food and Drug Administration has approved the groundbreaking, first-in-class drug Erivedge (vismodegib, Genentech) to treat adult patients with advanced and metastatic basal cell cancers.
Cleared under the FDA’s priority review program — which allows an expedited six-month evaluation of drugs that may offer major treatment advances — Erivedge 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 metastatized.
Erivedge is taken in pill form once a day. It works by inhibiting the Hedgehog pathway, which is active in most basal cell cancers and only a few normal tissues, such as hair follicles, according to the FDA website.
