Methods of treating heart failure with agonists of hypocretin receptor 2
View Patent ↗Methods of treating individuals for heart failure are disclosed. In particular, the invention relates to methods of treating individuals for heart failure with agonists of hypocretin receptor 2. The invention further relates to the use of genetic analysis of the single nucleotide polymorphism rs7767652, which resides immediately upstream of the HCRTR2 gene, to identify individuals in need of treatment for heart failure who are predicted to be more responsive to medical intervention.
1. A method of treating an individual for heart failure, the method comprising administering a therapeutically effective amount of an agonist of hypocretin receptor 2 (HCRTR2) to the individual, wherein the agonist of HCRTR2 is selected from the group consisting of orexin-A, orexin-B, [Alal I,D-Leul5]-orexin B, and SB-668875.
2. The method of claim 1 , wherein the agonist of HCRTR2 is administered according to a regimen selected from the group consisting of a daily dosing regimen, a twice-a-week dosing regimen, or a three-times-a-week dosing regimen.
3. The method of claim 1 , wherein multiple cycles of the method of treatment are administered to the individual for a time period sufficient to effect at least a partial recovery of heart function.
4. The method of claim 3 , wherein the time period is one of either at least 6 months or at least 12 months.
5. The method of claim 4 , wherein the individual shows at least a 10% improvement in left ventricular function.
6. The method of claim 4 , wherein the individual shows at least a 20% improvement in left ventricular function.
7. The method of claim 1 , wherein the agonist is administered orally, intravenously, intra-arterially, subcutaneously, intracerebroventricularly, intrathecally, or intranasally.
8. The method of claim 1 , further comprising treatment with one or more other agents for treating heart failure selected from the group consisting of an angiotensin converting enzyme (ACE) inhibitor, an angiotensin II receptor blocker (ARB), a beta-blocker, digoxin, a diuretic, a blood vessel dilator, potassium, magnesium, an aldactone inhibitor, a calcium channel blocker, and an inotrope.
