Use of growth hormone releasing factor analogs in treating patients suffering from wasting
View Patent ↗The present invention provides methods for using growth hormone releasing factor analogs of the formula (A), X-GRF Peptide, and pharmaceutically acceptable salts thereof, for increasing muscle function in a subject. Also disclosed herein are corresponding methods, packages and compositions.
1. A method of increasing muscle function in a subject suffering from severe wasting, said method comprising administering to said subject the GRF analog (hexenoyl trans-3)hGRF(1-44)NH 2 (SEQ ID NO: 7), wherein said subject has at least one of the following characteristics:
(a) said subject has a body mass index less than or equal to 20;
(b) said subject has a weight less than 90% of ideal body weight;
(c) said subject is a male and said subject has a fat free mass index less than or equal to 16; or
(d) said subject is a female and said subject has a fat free mass index less than or equal to 15.
2. The method of claim 1 , wherein said muscle function is selected from the group consisting of:
(a) muscle strength;
(b) muscle endurance; and
(c) both (a) and (b).
3. The method of claim 2 , wherein said muscle function is muscle strength.
4. The method of claim 3 , wherein said muscle strength is peripheral muscle strength.
5. The method of claim 2 , wherein said muscle function is muscle endurance.
6. The method of claim 1 , wherein said administering reduces a parameter selected from the group consisting of:
(a) breathing discomfort;
(b) leg discomfort; and
(c) both (a) and (b).
7. The method of claim 1 , wherein said administering increases lean body mass in said subject.
8. The method of claim 1 , wherein said administering decreases fat mass in said subject.
9. The method of claim 1 , wherein said wasting is associated with a condition selected from the group consisting of chronic obstructive pulmonary disease, chronic renal failure, congestive hear failure, human immunodeficiency virus infection, acquired immunodeficiency syndrome, cancer, malnutrition, frailty, immobilization paraplegia and spinal disorder.
10. The method of claim 1 , wherein said GRF analog is administered through a route selected from the group consisting of intravenous, oral, transdermal, subcutaneous, mucosal, intramuscular, intranasal, intrapulmonary, parenteral, intrarectal and topical.
11. The method of claim 1 , wherein said GRF analog is administered in a dose from about 0.0001 mg to about 4 mg.
12. The method of claim 11 , wherein said GRF analog is administered in a dose selected from the group consisting of about 1 mg and about 2 mg.
