One Man's Mission to Revive a Forgotten Cancer Drug

For the past decade, the Dutch immunologist Jacques (Sjaak) Neefjes has been on a mission to bring back a cancer drug that hasn’t been available in Europe since 2004. “I’m still flabbergasted that a compound that could have helped thousands of people was taken off the market,” says Neefjes. Why it was removed seems something of a mystery, but as far as he can tell, it was simply a lack of demand.
