"A 150-person study is now under way, and includes a control group."
I'm curious, the latest study which is presumably what triggered this story, involved no control group, yet they mention a smaller study from 2011 which did use a control.
If this really does hint at a breakthrough, why did it take so long to follow up on the first study, and why did this one not use a control group?
"According to protocol for the previous randomized KTS-1-2008 study, patients assigned to the placebo group should be given the opportunity to participate in a new open-label study with rituximab. The protocol for the present study was designed to learn about the therapeutic efficacy of rituximab maintenance treatment, for response rates and response durations. Also, the experiences could form the basis for design of a future randomized, double-blind and placebo-controlled trial."
