MIXTURES OF DRUG-OLIGOMER CONJUGATES COMPRISING POLYETHYLENE GLYCOL, USES THEREOF, AND METHODS OF MAKING SAME
First Claim
1. A substantially purely monodispersed mixture of conjugates, each conjugate comprising an insulin drug coupled to at least one oligomer, wherein the oligomer comprises a polyethylene glycol moiety having at least 2 polyethylene glycol subunits, wherein at least 95% of the conjugates have the same molecule weight and same molecular structure.

Abstract
A non-polydispersed mixture of conjugates in which each conjugate in the mixture comprises a drug coupled to an oligomer that includes a polyalkylene glycol moiety is disclosed. The mixture may exhibit higher in vivo activity than a polydispersed mixture of similar conjugates. The mixture may be more effective at surviving an in vitro model of intestinal digestion than polydispersed mixtures of similar conjugates. The mixture may result in less inter-subject variability than polydispersed mixtures of similar conjugates.
