You did read it correctly. That doesn't mean to say that Cell Cept and Rituxan don't help some people. They just don't meet enough of the critieria standards and don't show consistent improvement in managing the disease.
Since these drugs are helpful for some individuals some doctors are still prescribing them off label. I use Cell Cept as a maintenance drug with pretty good success. When things get bad, I get Rituxan to bring me back to a base level.
