Four of the nine patients who got the highest dose of miravirsen
temporarily cleared the virus after five injections. “That compares very
well to current treatments,” Janssen says.
One of the drugs in the pipeline, called miravirsen, may be able to
stop the virus with little side effects, doctors from University Health
Network in Toronto, Canada, reported Wednesday.
Their findings, published in The New England Journal of Medicine, are
preliminary — the doctors gave the drug to just 27 patients for about a
month. (Another 9 patients in the study were given a placebo.) But the
study is still drawing attention because it offers proof-of-concept for a
whole new class of drugs, called RNA interference drugs.
