Facial angiofibroma from tuberous sclerosis (adults and children age 6 years and older)
How Hyftor (sirolimus) works
Hyftor (sirolimus) is a mTOR inhibitor. This means that it blocks mTOR, a protein that helps control how our cells grow and survive. People who have tuberous sclerosis have broken copies of the genes that turns on mTOR, so mTOR becomes overly active. This leads to the growth of angiofibroma. While the exact way Hyftor (sirolimus) works in tuberous sclerosis isn't known, it's thought to ease the appearance angiofibroma by preventing mTOR from becoming too active.
