Abstract

Pharmaceutical formulations, kits and vessels are provided for delivering decitabine to a patient suffering from a disease in need of treatment with decitabine. The pharmaceutical formulation comprises decitabine solvated in a non-aqueous solvent that comprises glycerin, propylene glycol, polyethylene glycol, or combinations. Such formulations are more chemically stable than conventional liquid formulations of decitabine containing more than 40% water in volume. The pharmaceutical formulations can be used for any disease that is sensitive to the treatment with decitabine, such as hematological disorders and cancer.

Claims (16)

1. A kit, comprising:

a first vessel containing decitabine in solid form; and

a second vessel containing a diluent comprising glycerin, propylene glycol, polyethylene glycol or combinations thereof, and less than 40% water in volume in the diluent.

2. The kit of claim 1 , wherein decitabine is in a form of lyophilized powder.

3. The kit of claim 1 , wherein the diluent comprises less than 10% water in volume.

4. The kit of claim 1 , where the amount of decitabine in the first vessel is between 0.1 and 200 mg.

5. The kit of claim 1 , where the amount of decitabine in the first vessel is between 5 and 50 mg.

6. The kit of claim 1 , where the diluent is a combination of propylene glycol and glycerin, and the concentration of propylene glycol in the diluent is between 20–80%.

7. The kit of claim 1 , where the diluent is a combination of polyethylene glycol and glycerin, and the concentration of polyethylene glycol in the diluent is between 10–40%.

8. The kit of claim 1 , where the diluent is a combination of propylene, polyethylene glycol and glycerin, and the concentration of propylene glycol and polyethylene glycol in the diluent is between 20–80% and between 10–40% in volume, respectively.

9. The kit of claim 1 , wherein the diluent further comprises an acidifying agent.

10. The kit of claim 9 , wherein the acidifying agent is selected from the group consisting of ascorbic acid, citric acid, tartaric acid, lactic acid, oxalic acid, formic acid, benzene sulphonic acid, benzoic acid, maleic acid, glutamic acid, succinic acid, aspartic acid, diatrizoic acid, and acetic acid.

11. The pharmaceutical formulation of claim 9 , wherein the inorganic acid is selected from the group consisting of hydrochloric acid, sulphuric acid, phosphoric acid, and nitric acid.

12. The kit of claim 1 , wherein the diluent is anhydrous and the second vessel contains a drying agent.

13. The kit of claim 1 , further comprising: a written instruction describing how to mix solid decitabine and the diluent to form a pharmaceutical formulation.

14. The kit of claim 13 , wherein the instruction further describes how to administer the resulting pharmaceutical formulation to a patient.
