A team at Aarhaus University in Demark tried using a chemotherapy drug, romidepsin, which is used in lymphoma. Six HIV patients with undetectable levels of the virus were enrolled into trial. They each received a reduced dose of romidepsin once a week for three weeks. There was a noticeable jump in viral levels in the blood in five of the patients.
One of the scientists involved, Dr Ole Sogaard, told the BBC: "Every step forward is always exciting, and I think this is quite important." He said there had been a lot of scepticism about the drug being potent enough.
