Enzon Pharmaceuticals initiates treatment in PEG-SN38 Phase 1 study for pediatric cancer patients

Enzon Pharmaceuticals, Inc. today announced that the first patient has been treated in the Phase 1 study of PEG-SN38 for pediatric cancer patients. PEG-SN38 or EZN-2208 is Enzon's PEGylated form of SN38, the active metabolite of the cancer drug Camptosar® (irinotecan HCl injection). The study is designed to find the recommended dose of PEG-SN38 in pediatric patients. The PEG-SN38 compound is currently being evaluated in Phase 2 studies for metastatic colorectal and breast cancer.

They say the treatment - which is given just once - could potentially do the same in people at the beginning stages of the disease.

Calif. small businesses can keep non-conforming health plans next year

Elsewhere, a lawsuit accuses a big California insurer of deceptive enrollment practices, and consumers see that provider lists are often out-of-date and inaccurate.

Embryonic stem cell research has not made good on taxpayer investment

In 2004 Robert Klein, chairman of the California Institute of Regenerative Medicine (CIRM), helped pass Proposition 71, establishing the CIRM with a state taxpayer-funded $3 billion budget for ten years. The measure was passed with promises of affordable cures for virtually all diseases, cures specifically from embryonic stem cells and cloning, as well as tremendous financial payback for the citizens of California. The Los Angeles Times recently noted that Klein plans to seek up to $3 billion more from state taxpayers for his stem cell fiefdom.
