“…Thus, the response rate has been adjusted. There is lack of robust evidence of improved response by increasing the dose in non-responders [5], although studies indicate that the response rate may be increased by up to 12% in 8 weeks [17], and up to 17% in 12 weeks [18], by doubling the dose. We have assumed that by 8 weeks (two treatment cycles), the EPO response rate is 70% to EPO single dose, and when doubling the dose for nonresponders after 4 weeks (one treatment cycle) the response rate will be 80%.…”
