RPR licenses Enzon's Oncaspar for cancer

Executive Summary

Rhone-Poulenc Rorer is licensing the exclusive right to develop and market Enzon's cancer drug Oncaspar (PEG-modified L-asparaginase enzyme, or pegaspargase) in the US and Canada. Oncaspar is native L-asparaginase modified with Enzon's Pegnology, a delivery technology that attaches strands of polyethylene glycol to the drug to overcome the hypersensitivity problem. PEG-modification disguises the agent from potential attack by the immune system and extends the drug's half-life of circulation in the body--Oncaspar has to be injected only once every two weeks.
