Devices, formulations, and methods for delivery of multiple beneficial agents
View Patent ↗The present invention relates to osmotic delivery devices, formulations, and methods for delivery of two or more beneficial agents. In one aspect, the present invention provides osmotic delivery devices useful for substantially concurrent administration of two or more beneficial agents. In another aspect, the present invention provides beneficial agent formulations for use in the osmotic delivery devices. The formulations include formulations wherein beneficial agents are soluble in the vehicle, suspension formulations comprising particle formulations of one or more beneficial agent, and combinations thereof. Further, methods for treatment of a variety of diseases or conditions using two or more beneficial agents are disclosed, wherein the methods are preferably practiced using the osmotic delivery devices and/or formulations of the invention.
1.

2. The device of claim 1 , wherein the two or more polypeptides are formulated into one particle formulation that is suspended in the vehicle.
3. The device of claim 1 , wherein the first polypeptide is formulated into a first particle formulation and the second polypeptide is formulated into a second particle formulation, and the first and second particle formulations are suspended in the vehicle.
4. The device of claim 1 , wherein the first polypeptide is exenatide.
5. The device of claim 1 , wherein the solvent is selected from the group consisting of lauryl lactate, lauryl alcohol and benzyl benzoate.
6. The device of claim 1 , wherein the polymer is polyvinylpyrrolidone.
7. The device of claim 4 , wherein the polymer is polyvinylpyrrolidone.
8. The device of claim 1 , wherein the solvent is benzyl benzoate and the polymer is polyvinylpyrrolidone.
9. The device of claim 4 , wherein the solvent is benzyl benzoate and the polymer is polyvinylpyrrolidone.
10. The device of claim 1 , wherein the vehicle comprises about 25 wt % to about 80 wt % polymer and about 75 wt % to about 20 wt % solvent.
11. The device of claim 4 , wherein the vehicle comprises about 25 wt % to about 80 wt % polymer and about 75 wt % to about 20 wt % solvent.
12. The device of claim 3 , wherein the first particle formulation and the second particle formulation comprise a carbohydrate, an antioxidant, and a buffer.
13. The device of claim 2 , wherein the particle formulation comprises a carbohydrate, an antioxidant, and a buffer.
14. The device of claim 13 , wherein the carbohydrate is a non-reducing sugar, the antioxidant is an amino acid, and the buffer is an organic buffer.
15. The device of claim 14 , wherein the non-reducing sugar is selected from the group consisting of sucrose, trehalose, and raffinose.
16. The device of claim 14 , wherein the amino acid is selected from the group consisting of cysteine, methionine, and tryptophan.
17. The device of claim 14 , wherein the organic buffer is selected from the group consisting of citrate, histidine, succinate, and tris.
18. The device of claim 2 , wherein the solvent is benzyl benzoate and the polymer is polyvinylpyrrolidone, and the vehicle comprises about 25 wt % to about 80 wt % polyvinylpyrrolidone and about 75 wt % to about 20 wt % benzyl benzoate, and the particle formulation further comprises sucrose, methionine, and citrate buffer.
19. The device of claim 1 , wherein the vehicle has a viscosity of between about 12,000 to about 18,000 poise at 33° C.
20. A method of treating a disease or condition in a subject in need of treatment, comprising: providing the osmotic delivery device of claim 1 to the subject, wherein (i) the osmotic delivery device delivers a therapeutically effective amount of the two or more polypeptides to treat the disease or condition, and (ii) the disease or condition is selected from the group consisting of type ii diabetes, being overweight, and obesity.
21. The method of claim 20 , wherein (i) the first polypeptide is exenatide, and (ii) the two polypeptides are formulated into one particle formulation that is suspended in the vehicle or the first polypeptide is formulated into a first particle formulation and the second polypeptide is formulated into a second particle formulation and the first and second particle formulations are suspended in the vehicle.
