Abstract
Methods and compositions are taught that may be used to administer specific bioactive polypeptides, known as T20 and T1249 to a patient, e.g., as a method of treating a disease or disease state. In particular, the invention teaches carrier hydrogel composition that contain (a) a polymer material and (b) an effective dose of T20, T1249 or a derivative thereof. The polymer materials used in the carrier hydrogel composition preferably have reverse gelation properties and exist as a liquid, aqueous solution at temperatures below physiological temperatures (e.g., below the body temperature of a patient) but form hydrogels under physiological conditions (e.g., at temperatures at or near the body temperature of a patient). The carrier hydrogel compositions may thus be administered to a patient by injection while they are in a liquid state. Upon administration the carrier hydrogel compositions then form hydrogels with the T20 and/or T1249 polypeptides embedded therein. The T20 and/or T1249 polypeptides are thereby released with improved pharmacokinetic properties and bioavailability. The invention thus provides methods for administering T20 and T1249 polypeptides to a patient by administer…
