This application claims priority to U.S. Provisional Application No. 62/137,558, filed March 24, 2015, the entire contents of which are incorporated herein by reference.
Statement Regarding Federal Funding
Embodiments of the present invention were not conceived or reduced to practice with Federal sponsorship.
Background of the Invention Polysaccharides are used as cosmetic fillers and as a component of injectable drug delivery systems. When polysaccharides are placed in the body as a filler or as a drug delivery system, the polysaccharides may have a long period of time before such are resorbed into the body through metabolism or other means.
Summary of the Invention Embodiments of the present invention facilitate the use of polysaccharides, particularly as such polysaccharides are used as fillers and drug delivery vehicles. Embodiments of the present invention allow the polysaccharide to be modified in vivo or in vitro to impart special physical and chemical properties. For example, without limitation, the physical properties of texture, feel, resistance to pressure, viscosity and the like can be altered or modified, in vivo or in vitro. Similarly, the chemical properties resistance to degradation and speed of degradation can be modified or altered.
The modification of physical and chemical features of a polysaccharide used as a filler or drug delivery system allows the health practitioner to modify the filler mass after it has been placed in the body or prior to placement in the body. As used herein, the term, "mass" refers to the polysaccharide material and the surrounding space it occupies. For example, polysaccharide fillers used for cosmetic purposes typically comprise solutions of 1.0 to 5.0 %. These solutions may also comprise other materials to improve the flow or feel of the filler, such as hyaluronic acid, and anesthetic agents to address the potential discomfort during the administration of the filler. Anesthetic agents are well known in the art and include, without limitation, lidocaine. These fillers are administered to the deep layer of the skin. An example of a filler of this type is described in PCT/IB2014/060322 to Ghimas SPA, the entire content of which is incorporated herein by reference. One embodiment of the present invention is directed to a method of altering or modifying a mass comprising a polysaccharide held in the body of an animal. The method comprises the steps of administering an effective amount of an enzyme for the polysaccharide to the mass. The enzyme can be administered to the mass prior to the mass being placed in the body or after the mass has been placed in the body. One embodiment of the method features a polysaccharide having one or more sugars selected from the group consisting of D-galactose and 3, 6-anhydro-L-galactopyranose. These sugars are the constituents of algarose. Algarose is used as a dermal filler and as a drug delivery vehicle. As used herein, a "drug delivery vehicle" comprises a polysaccharide and one or more drugs. One embodiment of the method features an enzyme, alpha-galactosidase. The enzyme is known in recombinant forms asagalsidase, in alpha and beta forms. For example, without limitation, the enzyme is selected from the group consisting of agalsidase alpha and agalsidase beta. Algalsidase beta is sold under the mark FABRAZYME ® (Genzyme, Cambridge, MA 02142). Algalsidase alpha is sold in Europe under the mark REPLAGAL ® (Shire, Dublin, Ireland).
Wherein the mass is a delivery vehicle for one or more drugs, the enzyme has utility to remove the polysaccharide, control the delivery or release of drug and minimize the mark on the skin from the injection of drug. For example, without limitation, one embodiment of an invention directed to a drug delivery system comprises a polysaccharide and an enzyme for said polysaccharide held in a vessel for reconstitution. Upon reconstitution, the enzyme begin metabolizing the polysaccharide. This metabolizing may continue after injection of the drug delivery system into a patient. As used herein, the term "drug" is used to refer to any compound or compounds used to effect a biological change or treat a medical condition. The drug may be incorporated into the polysaccharide prior to reconstitution or after
reconstitution. Examples of drugs include without limitation, lidocaine, and other anesthetic agents, onabotulinemtoxin A (BOTOX ®, Allergan) and other aesthetic agents. A further embodiment of the present invention is directed to a kit for performing dermal filling procedures or for the administration of drug. The kit comprises a polysaccharide for forming a mass in the body of an animal and an enzyme for degrading the polysaccharide for administration to the mass held in the body to effect a modification or speeding the resorption of said mass.
One embodiment of the present kit features a polysaccharide having one or more sugars selected from the group consisting of D-galactose and 3, 6-anhydro-L-galactopyranose. These sugars are constituents of the polysaccharide, agarose.
One embodiment features the enzyme, agalsidase. The agalsidase is selected from the group consisting of agalsidase alpha and agalsidase beta.
These and other features and advantages will be apparent to those skilled in the art upon viewing the figure which is briefly described below and studying the details description that follows.
Brief Description of the Drawings Figure 1 depicts a kit embodying features of the present invention. Detailed Description of the Invention
Embodiments of the present invention will now be described in detail with respect to a kit for performing dermal filling procedures or for the administration of drug. The present description is directed to embodiments which are considered to be the best mode to practice the present invention at the time of the writing of the present description. Those skilled in the art will recognize that the understanding of the best mode may change in time. Those skilled in the art will also recognize that the features of the present invention described are subject to alteration and modification and such that the present discussion should not be considered limiting. Turning now to Figure 1, a kit, generally designated by the numeral 11, embodying features of the present invention is depicted. The term "kit" is used to denote a bundled assembly of parts and constituents for performing a method. The kit 11 comprises two vials, a first vial 13 containing a polysaccharide for forming a mass in the body of an animal and a second vial 15 containing an enzyme for degrading the polysaccharide for administration to the mass held in the body. The first vial 13 and second vial 15 are bundled or held in a package 17 with means for administering the polysaccharide and means for administering the enzyme, in the form of first syringe 19 and second syringe 21 , and instructions 23.
The first vial 13 contains a polysaccharide for forming a mass in the body of an animal or patient. The polysaccharide can be pre-made and in a final form ready for administration or be lyophilized for reconstitution with water. The first syringe 19 is used to withdraw the reconstituted or pre-made polysaccharide for injection into an animal or patient. For example, a human subject may use the mass to conceal wrinkles or to build bulk to areas of the body showing signs of atrophy or for which a fuller appearance is desired. The present kit features a polysaccharide having one or more sugars selected from the group consisting of D-galactose and 3, 6-anhydro-L-galactopyranose. These sugars are constituents of the polysaccharide, agarose, which is used as a dermal filler. Agarose is sold as a dermal filler under the mark ALGINESS ®.
The second vial 15 contains an enzyme to effect a modification or speeding the resorption of the mass. The enzyme can be pre-made and in a final form ready for administration or be lyophilized for reconstitution with water. The second syringe 21 is used to withdraw the reconstituted or pre-made polysaccharide for injection into the mass. For example, in a human subject using the mass to conceal wrinkles or to build bulk to areas of the body showing signs of atrophy, the subject may desire the mass to have a softer feel. The enzyme is placed in the mass and the mass manipulated to distribute the enzyme where the enzyme may effect a degradation of the polysaccharide. The degradation of the polysaccharide softens the mass.
Embodiments of the present invention facilitate the use of polysaccharides, particularly as such polysaccharides are used as fillers and drug delivery vehicles. Embodiments of the present invention allow the polysaccharide to be modified in vivo or in vitro to impart special physical and chemical properties. That is, the enzyme can be distributed into the
polysaccharide prior to administration of the polysaccharide or after administration of the polysaccharide to create a desired physical property of texture, feel, resistance to pressure, viscosity and the like. Similarly, the chemical properties of resistance to degradation and speed of degradation can be modified or altered.
The modification of physical and chemical features of a polysaccharide used as a filler or drug delivery system allows the health practitioner to modify the filler mass after it has been placed in the body or prior to placement in the body.
The use of the kit and the instructions 21 will now be described with respect to an
embodiment of the present invention directed to a method of altering or modifying a mass comprising a polysaccharide held in the body of an animal. The instructions direct the user to reconstitute the polysaccharide held in first vial 13 and the enzyme held in second vial 15 if reconstitution is needed. The instructions 21 direct the user to administer polysaccaride held in the first vial 13. The instructions 21 further direct the user to administer an effective amount of an enzyme for the polysaccharide to the mass. The enzyme can be administered to the mass prior to the mass being placed in the body or after the mass has been placed in the body.
Embodiments of the method and kits feature a polysaccharide having one or more sugars selected from the group consisting of D-galactose and 3, 6-anhydro-L-galactopyranose. These sugars are the constituents of algarose. Algarose is used as a dermal filler and as a drug delivery vehicle.
Embodiments of the method and kits features an enzyme, agalsidase. For example, without limitation, the enzyme is selected from the group consisting of agalsidase alpha and agalsidase beta. Algalsidase beta can be administered in doses up to 1 mg/ kg body weight, but is typically used in an amount based on the mass of polysaccharide. Monographs for such enzymes are available from the respective manufacturers and are incorporated herein by reference.
Thus, the present invention has been described in detail with the understanding that the present discussion is subject to modification and alteration without departing from the teaching. Therefore, the present invention should not be limited to the precise details but should encompass the subject matter of the claims that follow and their equivalents.
