Anti-CD20

There seems to be a strong interest to develop a Rituximab Mk II. Just the other day Genentech and Idec said that they had agreed to do so.

Genentech and IDEC Announce Humanized Anti-CD20 Antibody Development Collaboration
Friday June 20, 4:19 pm ET

SOUTH SAN FRANCISCO, Calif. and SAN DIEGO--(BUSINESS WIRE)--June 20, 2003--Genentech, Inc. (NYSE:DNA - News) and IDEC Pharmaceuticals Corporation (Nasdaq:IDPH - News) today announced plans to develop one or more new humanized anti-CD20 antibodies targeting B-cell disorders for a broad range of indications. Financial terms of the profit-sharing collaboration were not disclosed.

Genentech and IDEC plan to file an investigational new drug application (IND) on their first humanized anti-CD20 antibody by the end of this year. The companies plan to work efficiently together to develop and commercialize additional anti-CD20 products that are targeted for specific patient populations, depending on the severity of their B-cell disorder. The primary focus of this collaboration will be to develop and launch a humanized anti-CD20 molecule while evaluating the utility for more efficacious follow-on humanized molecules.


After that it turned out that it is now Biogen who is Genentech's partner, but I guess they don't mind as long as they can get the mAb out of the door.

AMEV
In the beginning of this year, AMEV announced that their thinking was more or less the same.

And today we had the announcement from Genmab, who wants to try to develop a fully human version.

No doubt there may very well be other candidates under development which I have not noticed.

From a fully human standpoint isn't it somewhat surprising that DNA/Idec went with a humanized version. (Rituxan is as far as I know only chimeric - which is even more surprising).
