The article is already off to a bad start, assuming the existing therapy they&#x27;re talking about is Pegetron:<p>&gt; The interferon-based treatments weren&#x27;t successful half the time, and the side effects were so debilitating few patients could endure the months-long punishing protocol.<p>If the success rate is 50%, I would say that&#x27;s pretty good, especially since we&#x27;re talking about treatment, not just managing the disease (as we can only do nowadays with HIV). And from the product monograph: &quot;The most frequently reported adverse reactions were mostly mild to moderate in severity and were manageable without the need for modification of doses or discontinuation of therapy. &quot;<p>But no doubt, the pre-existing therapy sure has a pile of side-effects.
