Melanoma patients who took the pill, known as RG7204, found the size of their tumors had shrunk by 80 percent, according to scientists at the Royal Marsden National Health Service Trust in London.

The drug works by finding the patients’ mutated gene, called BRAF, and shrinking the tumors.

Larkin hopes to the drug will become available to the public by 2012.
