Thanks BobLLL from Yahoo for the reference and comments:

"There are two large studies going on now on to gather more data on Rituxan. Over a thousand patients in the two. A huge list of major cancer centers participating. Unlike the Oncolym study, these studies can be confirmed on the NCI site.

Look for yourself, search for Lymphoma, Adult, NonHodgins/ Phase III/ Modality: monoclonal antibody Oh, yeah, you'll also see another study of Bexxar by another group of scientists too dumb to read this thread Nothing about Oncolym. I'll leave it to the bulls to explain why this also is irrelevant. After all, what does NCI know about this stuff?"

Richard, just trying to tempt you to take an interest in IDPH, TCLN and CLTR. It isn't that I don't think CD20 MAbs won't be ineffective, its just that I'm unsure that they will.

Meanwhile, [to those interested], Tarken's lymphoma was strongly CD20 positive, but no Rituxan treatment anyway! Does Rituxan have such cunning that it can discriminate between CD20 on intermediate grade which has changed from low grade and is ineffective on CD20 cells which are given the somewhat arbitrary designation intermediate grade instead of low grade or indolent. Since indolent can metamorphose into intermediate, the distinction seems capricious.

Surely the only thing that matters in regard to Rituxan is strongly expressed CD20.

Any ideas anyone? Why is Rituxan only effective on low grade CD20?
