Mucoadhesive drug delivery devices and methods of making and using thereof
First Claim
1. A mucoadhesive device, comprising one or more purified free-form proteins, wherein one of the purified proteins included in the mucoadhesive device is ovalbumin, combined with one or more pharmacologically active agents, one or more mucoadhesive agents and one or more biocompatible solvents formed into a cohesive body or solidified cohesive mass that is formed into a mucoadhesive device and having the purified proteins in an amount of about 15% to 85% by weight of the mucoadhesive device, and the mucoadhesive agents in an amount of about 0.1% to 35% by weight of the mucoadhesive device, wherein the mucoadhesive device is configured to have a form such that the mucoadhesive device is capable of adhering to mucosal tissue of a patient for the delivery of the one or more pharmacologically active agents to the patient.

Abstract
The present invention relates to mucoadhesive drug delivery devices and their methods of preparation and use. More specifically the present invention relates to mucoadhesive drug delivery devices comprising one or more biocompatible purified proteins combined with one or more biocompatible solvents and one or more mucoadhesive agents. The mucoadhesive drug delivery devices may also include one or more pharmacologically active agents. The drug delivery devices of the present invention adhere to mucosal tissue, thereby providing a vehicle for delivery of the pharmacologically active agent(s) through such tissue.

- 1. A mucoadhesive device, comprising one or more purified free-form proteins, wherein one of the purified proteins included in the mucoadhesive device is ovalbumin, combined with one or more pharmacologically active agents, one or more mucoadhesive agents and one or more biocompatible solvents formed into a cohesive body or solidified cohesive mass that is formed into a mucoadhesive device and having the purified proteins in an amount of about 15% to 85% by weight of the mucoadhesive device, and the mucoadhesive agents in an amount of about 0.1% to 35% by weight of the mucoadhesive device, wherein the mucoadhesive device is configured to have a form such that the mucoadhesive device is capable of adhering to mucosal tissue of a patient for the delivery of the one or more pharmacologically active agents to the patient.
- 17. A mucoadhesive device, comprising ovalbumin in a free-form state, combined with one or more pharmacologically active agents, one or more mucoadhesive agents and one or more biocompatible solvents and formed into a cohesive body or solidified cohesive mass that is formed into a mucoadhesive device having a homogenous distribution of the ovalbumin in an amount of about 15% to 85% by weight of the mucoadhesive device, pharmacologically active agents, mucoadhesive agents in an amount of about 0.1% to 35% by weight of the mucoadhesive device and biocompatible solvents, wherein the mucoadhesive device is configured to have a form such that the mucoadhesive device is capable of adhering to mucosal tissue of a patient for the delivery of the one or more pharmacologically active agents to the patient.

32. A method of delivering one or more pharmacologically active agents through the mucosal tissue of a patient comprising the steps of:
adhering a mucoadhesive device to the mucosal tissue of a patient, said mucoadhesive device including one or more purified free-form proteins, wherein one of the purified proteins included in the mucoadhesive device is ovalbumin, combined with one or more pharmacologically active agents, one or more mucoadhesive agents and one or more biocompatible solvents to form a coatable composition, wherein the solvent content of the coatable composition is reduced and formed into a mucoadhesive device having a homogenous distribution of the purified proteins, pharmacologically active agents, mucoadhesive agents and biocompatible solvents, wherein the mucoadhesive device is configured to have a form such that the mucoadhesive device adheres to the mucosal tissue of the patient for the delivery of the one or more pharmacologically active agents to the patient. - View Dependent Claims (33, 34, 35, 36)

37. A method of making a mucoadhesive drug delivery device comprising:
-
(a) preparing a coatable composition including one or more biocompatible purified free-form proteins, wherein one of the purified proteins included in the mucoadhesive device is ovalbumin, one or more biocompatible solvents, one or more mucoadhesive agents and one or more pharmacologically active agents; (b) partially drying the coatable composition to reduce bulk solvent present in the system to form a solidified cohesive mass including a substantially homogenous distribution of purified proteins, solvents, mucoadhesive agents and pharmacologically active agents; and (c) processing the cohesive mass to form a mucoadhesive device, wherein the mucoadhesive device is processed to have a form such that the mucoadhesive device is capable of adhering to mucosal tissue of a patient for the delivery of the one or more pharmacologically active agents to the patient. - View Dependent Claims (38, 39, 40)
