Compositions and methods for lowering triglycerides without raising LDL-C levels in a subject on concomitant statin therapy
In various embodiments, the present invention provides compositions and methods for treating and/or preventing cardiovascular-related diseases in subject in need thereof.
1. A method of increasing a ratio of omega-3 fatty acids to total fatty acids in plasma or RBCs of a subject having baseline fasting triglycerides of about 500 mg/dl to about 1500 mg/dl, a baseline ratio of omega-3 fatty acids to total fatty acids in plasma of about 2.0 to about 4.4 or a baseline ratio of omega-3 fatty acids to total fatty acids in RBCs of about 4.0 to about 8.4, and on stable statin therapy, the method comprising administering to the subject a pharmaceutical composition comprising about 1 g to about 4 g of EPA per day, wherein upon administering the composition to the subject daily for a period of 12 weeks, the subject exhibits an increase in the ratio of omega-3 fatty acids to total fatty acids in plasma and/or RBCs of at least 50% compared to a control subject on stable statin therapy without EPA, wherein the control subject also has baseline fasting triglycerides of about 500 mg/dl to about 1500 mg/dl.
2. The method of claim 1 , wherein the increase is at least about 60%.
3. The method of claim 1 , wherein the increase includes an increase in the ratio in plasma of at least 60%.
4. The method of claim 1 , wherein the increase includes an increase in the ratio in RBCs of at least 50%.
5. The method of claim 1 , wherein the omega-3 fatty acids include one or more of: α-linolenic acid, stearidonic acid, eicosatrienoic acid, eicosapentaenoic acid, ω-3 docosapentaenoic acid and docosahecaenoic acid.
6. The method of claim 1 , wherein the total fatty acids include one or more of: α-linolenic acid, stearidonic acid, eicosatrienoic acid, ω-3 arachidonic acid, eicosapentaenoic acid, ω-3 docosapentaenoic acid, docosahecaenoic acid, linoleic acid, γ-linolenic acid, eicosadienoic acid, dihomo-γ-linolenic acid, ω-6 arachidonic acid, adrenic acid, ω-6 docosapentaenoic acid, myristoleic acid, palmitoleic acid, cis-vaccenic acid, oleic acid, gondoic/gadoleic acid, erucic acid, nervonic acid, myristic acid, palmitic acid, stearic acid, arachidic acid, behenic acid and lignoceric acid.
7. The method of claim 1 , wherein the subject is administered about 2 g/day of EPA.
8. The method of claim 1 , wherein the subject is administered about 4 g/day of EPA.
9. The method of claim 1 , wherein the subject further exhibits no increase, no substantial increase, or a reduction in plasma and/or RBC levels of DHA compared to the control subject.
