Future treatment Genotype 1 Genotype 3 SVR about 90% Interferon plus 2 oral drugs 12 weeks 2 or 3 Oral drugs 24 weeks With Prediction Interferon/ribavirin 16 weeks • SVR better than 90% with • 2 or 3 oral drugs for 8-12 weeks • OR • Interferon plus 1 or 2 drugs for 12 weeks
So back to treating one person • The new treatments are much more expensive • SO • Get a lot more money? • In Scotland there will be some new money • Treat a lot less people? • Use some of the old treatments in some people. • Including a bit of Interferon
