Abstract

Disclosed is a conjugate of a protein having substantial L-asparagine amino hydrolase activity and polyethylene glycol. In particular, the polyethylene glycol has a molecular weight of about 5000 Da and the protein is an L-asparaginase from. The conjugate of the invention has shown superior properties such as maintenance of a high level of in vitro activity and an unexpected increase in half-life in vivo. Also disclosed are methods of producing the conjugate and use of the conjugate in therapy. In particular, a method is disclosed for use of the conjugate in the treatment of cancer, particularly Acute Lymphoblastic Leukemia (ALL).
