A cancer therapy using a virus that attacks tumor cells but not healthy ones has been approved in China, the first regulatory approval for this type of treatment anywhere in the world, according to the company that developed the treatment.
The drug is essentially a copy of one developed and then abandoned by an American biotechnology company. The move is an example of how some therapies can win quick approval in China, perhaps because regulatory hurdles are lower. China is also the only country so far to have given regulatory approval to any gene therapy.
