Spark prices its gene therapy as most expensive U.S. medicine!
"The first gene therapy in the U.S. approved last month to treat a rare, inherited form of blindness, now has a price tag: $850,000. The condition is rare, affecting between 1,000 and 2,000 people in the U.S. About 10-20 babies are born each year with RPE65-mutated retinal disease, Spark estimates."
