Abstract

The present invention provides coated tablet formulations comprising neratinib maleate, and improved methods for making such coated tablets.

Claims (18)

1. A pharmaceutically acceptable composition comprising: a granulation comprising intragranular components: (a) 10-70 weight percent neratinib maleate; (b) 15-65 weight percent of one or more fillers; (c) 0-8 weight percent of one or more disintegrants; (d) 0.2-8 weight percent of one or more glidants; and (e) 5-15 weight percent of one or more surface modifying agents; wherein the granulation is combined with extragranular components: (f) 1-25 weight percent of one or more fillers; (g) 0-8 weight percent of one or more disintegrants; and (h) 0.1-3 weight percent of one or more lubricants.

2. A pharmaceutically acceptable composition comprising intragranular components: 10-70 weight percent of neratinib maleate and 5-15 weight percent of povidone; and extragranular components: microcrystalline cellulose, crospovidone and magnesium stearate.

3. A pharmaceutically acceptable composition comprising intragranular components: (a) 10-70 weight percent of neratinib maleate; (b) 15-65 weight percent of mannitol, microcrystalline cellulose or a combination of both; (c) 0.5-8 weight percent crospovidone, croscarmellose sodium or a combination of both; (d) 0.2-8 weight percent colloidal silicon dioxide; and (e) 5-15 weight percent povidone; and extragranular components: (f) 1-25 weight percent of microcrystalline cellulose; (g) 1-8 weight percent of crospovidone; and (h) 0.5-3 weight percent of magnesium stearate.

4. A tablet comprising the composition of claim 3 .

5. A dry-filled capsule comprising the composition of claim 3 .

6. The composition according to claim 3 , wherein the amount of neratinib maleate is about 41 weight percent.

7. The composition according to claim 3 , wherein the amount of mannitol and microcrystalline cellulose, as an intragranular component, is about 50 weight percent.

8. The composition according to claim 3 , wherein the amount of crospovidone, as an intragranular component, is about 3 weight percent.

9. The composition according to claim 3 , wherein the amount of povidone, as an intragranular component, is about 5 weight percent.

10. The composition according to claim 3 , in the form of an oral dosage of 40 mg, 80 mg, or 240 mg.

11. A method for preparing a pharmaceutically acceptable composition, comprising: (1) spraying 5-15 weight percent of one or more surface modifying agents onto intragranular components of a granulation, said intragranular components comprising: (a) 10-70 weight percent neratinib maleate; (b) 15-65 weight percent of one or more fillers; (c) 0-8 weight percent of one or more disintegrants; and (d) 0.2-8 weight percent of one or more glidants; and (2) combining said coated intragranular components with extragranular components of the granulation, said extragranular components comprising: (e) 1-25 weight percent of one or more fillers; (f) 0-8 weight percent of one or more disintegrants; and (g) 0.1-3 weight percent of one or more lubricants.

12. The method according to claim 11 , wherein the surface modifying agent is povidone.

13. A method for treating cancer comprising administering an effective amount of a composition according to claim 1 ; wherein the cancer results from an aberrant tyrosine kinase receptor.

14. The composition according to claim 3 , wherein the amount of colloidal silicon dioxide, as an intragranular component, is about 2 weight percent.

15. The composition according to claim 3 , wherein the amount of neratinib maleate is about 35 weight percent.

16. The pharmaceutically acceptable composition of claim 3 , comprising intragranular components: (a) 10-70 weight percent of neratinib maleate; (b) 15-65 weight percent of mannitol and microcrystalline cellulose; (c) 0.5-8 weight percent of crospovidone; (d) 0.2-8 weight percent of colloidal silicon dioxide; and (e) 5-15 weight percent of povidone; and extragranular components: (f) 1-25 weight percent of microcrystalline cellulose; (g) 1-8 weight percent of crospovidone; and (h) 0.5-3 weight percent of magnesium stearate.

17. The pharmaceutically acceptable composition of claim 3 , comprising intragranular components: (a) 35 weight percent of neratinib maleate; (b) about 50 weight percent of mannitol and microcrystalline cellulose; (c) 3 weight percent of crospovidone; (d) 2 weight percent of colloidal silicon dioxide; and (e) 5 weight percent of povidone; and extragranular components: (f) 1.5 weight percent of microcrystalline cellulose; (g) 2 weight percent of crospovidone; and (h) 2 weight percent of magnesium stearate.

18. The pharmaceutically acceptable composition of claim 3 , comprising 40 mg of neratinib maleate.
