Abstract
Amorphous solid dispersions and pharmaceutical compositions of the protein kinase inhibitor dasatinib. The pharmaceutical compositions may be used in methods of treating a proliferative disorder such as cancer, or in methods of delivering dasatinib to patients without regard to whether the patient is concurrently administered a gastric acid-reducing agent, or without regard to whether the patient has an elevated gastric pH. The compositions may be particularly suitable for patients afflicted by achlorhydria or hypochlorhydria, or Helicobacter pylori infection. The compositions may be administered intact, or may be crushed prior to administration.
Claims (22)
1 . A method of delivering a therapeutically effective amount of dasatinib to a patient in need thereof, comprising:
(a) providing a pharmaceutical composition in the form of one or more crushable tablets;
(b) crushing the one or more crushable tablets to provide a powder; and
(c) orally administering the powder to the patient;
wherein the crushable tablets comprise an amorphous solid dispersion, the amorphous solid dispersion comprising dasatinib and a polymer that exhibits pH dependent solubility; and
wherein the dasatinib and the polymer that exhibits pH dependent solubility are present in the amorphous solid dispersion in a w/w ratio of 30:70 to 95:5 (dasatinib:polymer).
2 . The method of claim 1 , further comprising the step of dispersing the powder in a soft food prior to administration to the patient.
3 . The method of claim 1 , further comprising the step of dispersing the powder in a fruit preparation prior to administration to the patient.
4 . The method of claim 1 , further comprising the step of dispersing the powder in a fluid prior to administration to the patient.
5 . The method of claim 1 , further comprising the step of dispersing the powder in a juice prior to administration to the patient.
6 . The method of claim 1 , wherein the patient is a pediatric patient, a geriatric patient, or a patient that suffers from dysphagia.
7 . The method of claim 1 , wherein the patient is an adult patient, and the one or more crushable tablets comprise a total of 100 to 180 mg dasatinib.
8 . The method of claim 1 , wherein the patient is a pediatric patient, and the one or more crushable tablets comprise a total of 40 to 100 mg dasatinib.
9 . The method of claim 1 , wherein the polymer that exhibits pH dependent solubility comprises a methacrylic acid and ethyl acrylate copolymer.
10 . The method of claim 1 , wherein the polymer that exhibits pH dependent solubility comprises a methacrylic acid and ethyl acrylate copolymer that is insoluble in an aqueous medium at pH of 5 or lower, and soluble in an aqueous medium at pH 5.5 or greater.
11 . The method of claim 1 , wherein the dasatinib and the polymer that exhibits pH dependent solubility are present in the amorphous solid dispersion in a w/w ratio of 40:60 to 70:30 (dasatinib:polymer).
12 . The method of claim 1 , wherein the pharmaceutical composition is co-administered to the patient with a gastric acid-reducing agent.
13 . The method of claim 1 , wherein the pharmaceutical composition is co-administered to the patient with a standard dosage of a proton pump inhibitor.
14 . The method of claim 1 , wherein the patient has elevated gastric pH.
15 . The method of claim 1 , wherein the patient is suffering from a proliferative disorder.
16 . The method of claim 15 , wherein the proliferative disorder is Philadelphia chromosome-positive chronic myeloid leukemia.
17 . The method of claim 15 , wherein the proliferative disorder is Philadelphia chromosome-positive acute lymphoblastic leukemia.
