Methods for Treating Obesity and Disorders Associated with Hyperlipidemia in a Mammal
The disclosure relates to methods for treating hyperlipidemia in a mammal. The present disclosure also relates to methods for treating and/or controlling obesity in a mammal. The methods involve combination therapies using a microsomal triglyceride transfer protein (MTP) inhibitor (for example, AEGR-733 and implitapide) and a DGAT inhibitor (for example, JTT-553 or PF-04415060). Co-administration of the MTP inhibitor with the DGAT inhibitor produces a therapeutic benefit, for example, a reduction in the concentration of cholesterol and/or triglycerides in the blood stream, but with fewer or reduced side effects than when higher dosages of the MTP inhibitor are used during monotherapy to provide the same or similar therapeutic benefit.
1 . A method of reducing the concentration of cholesterol and/or triglycerides in the blood of a mammal in need thereof, comprising administering to the mammal a combination of a diacylglycerol acyltransferase (DGAT) inhibitor and a MTP inhibitor, wherein the method reduces the concentration of at least one of cholesterol or triglycerides in the blood but with a reduced incidence of an adverse event as compared to administration of the MTP inhibitor alone.
2 . A method of treating and/or controlling obesity in a patient in need thereof, comprising administering to the patient a combination of a diacylglycerol acyltransferase (DGAT) inhibitor and a MTP inhibitor, wherein method has a reduced incidence of an adverse event as compared to administration of the MTP inhibitor alone.
3 . The method of claim 1 , wherein the MTP inhibitor is N-(2,2,2-Trifluorethyl)-9-[4-[4-[[[4′-(trifluoromethyl)[1,1′biphenyl]-2-Yl]carbonyl]amino]-1-piperidinyl]butyl]9H-fluorene-9-carboxamide or pharmaceutically acceptable salts thereof.
4 . The method of claim 1 , wherein the MTP inhibitor is implitapide or pharmaceutically acceptable salts thereof.
5 . The method of claim 1 , wherein the MTP inhibitor is administered at about 2.5 mg/day to about 50 mg/day.
6 . The method of claim 5 , wherein MTP inhibitor is administered at about 10 mg/day.
7 . The method of claim 4 , wherein the MTP inhibitor is administered at about 20 to 40 mg/day.
8 . The method of claim 1 , wherein the DGAT inhibitor and the compound are administered together in the same dosage form.
9 . The method of claim 1 , wherein the DGAT inhibitor and the compound are administered in separate dosage forms.
10 . The method of claim 1 , wherein the mammal is a human.
11 . The method of claim 10 , wherein the human has at least one of: hyperlipidemia, hypercholesterolemia, hypertriglyceridemia, or hyperchylomicronemia.
12 . The method of claim 11 , wherein the hypercholesterolemia is homozygous or heterozygous familial hypercholesterolemia.
13 . The method of claim 1 , wherein the DGAT inhibitor is JTT-553 or PF-04415060.
14 . The method of claim 1 , wherein the adverse event is hepatic steatosis.
15 . A method of reducing the amount of hepatic triglyceride in a patient receiving a MTP inhibitor, comprising co-administering the MTP inhibitor and a DGAT inhibitor to the patient.
16 . The method of claim 15 , wherein the MTP inhibitor is N-(2,2,2-Trifluorethyl)-9-[4-[4-[[[4′-(trifluoromethyl)[1,1′biphenyl]-2-Yl]carbonyl]amino]-1-piperidinyl]butyl]9H-fluorene-9-carboxamide or pharmaceutically acceptable salts thereof.
17 . The method of claim 15 , wherein the MTP inhibitor is implitapide or pharmaceutically acceptable salts thereof.
18 . The method of claim 16 , wherein the MTP inhibitor is administered at about 2.5 mg/day to about 50 mg/day.
19 . The method of claim 17 , wherein the MTP inhibitor is administered at about 20 to 40 mg/day.
20 . The method of claim 15 , wherein the MTP inhibitor and DGAT inhibitor are administered at least daily.
21 . The method of claim 15 , wherein the amount of hepatic triglyceride in the patient's liver after one month is less than about 20% of the amount of hepatic triglyceride in a patient's liver if the MTP inhibitor is administered alone.
