The invention relates to the field of treatment or prevention of obesity-related disorders, atherosclerosis or a coagulation disorder. In particular, the present invention relates to the use of an activator of IFNλ receptor for the treatment or prevention of such disorders or conditions, and corresponding methods of treatment.
1. A method of treating an obesity-related disorder, atherosclerosis or a coagulation disorder, the method comprising administering to a subject in need thereof an effective amount of an activator of a lambda interferon (IFNλ) receptor, wherein the activator of the IFNλ receptor is an IFNλ polypeptide or a polynucleotide encoding the IFNλ polypeptide, and wherein the IFNλ polypeptide is a type III IFN.
2. The method of claim 1 , wherein the obesity-related disorder, atherosclerosis or the coagulation disorder is selected from the group consisting of obesity, hyperphagia, prediabetes, type 2 diabetes, gestational diabetes, insulin resistance, metabolic disease, metabolic syndrome, coronary heart disease, carotid artery disease, myocardial infarction, stroke, thrombosis, dyslipidemia, hyperlipidemia, hypercholesterolemia, atheromatic plaque formation, and atheromatic plaque rupture.
3. The method of claim 1 , comprising the therapeutic reduction of body weight or overweight in the subject.
4. The method of claim 1 , wherein the subject is a mammalian subject.
5. The method of claim 4 , wherein the subject is a human subject.
6. The method of claim 1 , wherein the activator of the IFNλ receptor is administered in combination with one or more further therapeutic agents.
7. The method of claim 6 , wherein the one or more further therapeutic agents are selected from the group consisting of insulin, metformin, meglitinides, sulfonylureas, glyburide, glipizide, glimepiride, canagliflozin, dapagliflozin, thiazolidinediones, pioglitazone, acarbose, pramlintide, exenatide, liraglutide, long-acting exenatide, albiglutide, dulaglutide, DPP-IV inhibitors, sitagliptin, saxagliptin, linagliptin, phentermine, diethylpropion, phendimetrazine, benzphetamine, oxyntomodulin, fluoxetine hydrochloride, topiramate, phentermine, bupropion, zonisamide, bupropion, naltrexone, xenical, cetilistat, GT 389-255, statins, cholesterol lowering drugs, proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitors, ACE inhibitors, aldosterone inhibitors, angiotensin II receptor blockers, beta-blockers, calcium channel blockers, antiplatelets, aspirin, clopidogrel, dipyridamole, anti-coagulants, warfarin, heparin, direct factor Xa inhibitors, direct thrombin inhibitors, hydralazine, diuretics, corticosteroids, and non-steroidal anti-inflammatory drugs.
8. The method of claim 1 , wherein the IFNλ polypeptide is a human IFNλ.
9. The method of claim 8 , wherein the IFNλ polypeptide is selected from the group consisting of IFNλ1, IFNλ2, IFNλ3 and IFNλ4.
10. The method of claim 1 , wherein the IFNλ polypeptide is homologous to the subject.
11. The method of claim 1 , wherein the IFNλ polypeptide is pegylated.
12. The method of claim 11 , wherein the IFNλ polypeptide is a monopegylated IFNλ polypeptide or an IFNλ polypeptide conjugated with a polyalkyl oxide moiety.
13. The method of claim 1 , wherein the activator of the IFNλ receptor is administered via intravenous, intraperitoneal, subcutaneous or intramuscular injection; via oral, topical or transmucosal administration; via nasal or pulmonary inhalation; or via gene-therapy.
14. The method of claim 1 , wherein the activator of the IFNλ receptor is administered
(i) weekly,
(ii) every two weeks, or
(iii) twice a week.
15. The method of claim 1 , wherein the activator of the IFNλ receptor is administered at a dose selected from
(i) 10 μg to 10 mg, 100 μg to 9 mg, 500 μg to 8 mg, 1 mg to 7 mg, 2 mg to 6 mg, and 5 mg; or
(ii) 0.1-150 μg/kg body weight, 0.5-100 μg/kg body weight, 1-90 μg/kg body weight, 10-80 μg/kg body weight, 20-70 μg/kg body weight, and 60 μg/kg body weight.
16. The method of claim 1 , wherein the activator of the IFNλ receptor is administered as a pharmaceutical composition comprising the activator of the IFNλ receptor and a pharmaceutically acceptable excipient.
17. The method of claim 1 , wherein the activator of the IFNλ receptor is the IFNλ polypeptide.
18. The method of claim 1 , wherein the IFNλ polypeptide comprises an amino acid sequence having at least 90% sequence identity to the amino acid sequence of SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, or SEQ ID NO: 5.
19. The method of claim 18 , wherein the IFNλ polypeptide comprises the amino acid sequence of SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, or SEQ ID NO: 5.
20. A non-therapeutic method of reducing body weight or overweight in a subject, the method comprising administering a non-therapeutically effective amount of an activator of IFNλ receptor to the subject, wherein the activator of the IFNλ receptor is an IFNλ polypeptide or a polynucleotide encoding the IFNλ polypeptide, and wherein the IFNλ polypeptide is a type III IFN, and optionally wherein the non-therapeutic reduction of body weight or overweight involves suppression of appetite and/or the suppression of overeating.
21. A method for determining susceptibility of a subject to treatment with an activator of IFNλ receptor, wherein the subject is suffering from an obesity-related disorder, atherosclerosis or a coagulation disorder, and wherein the method comprises administering the activator of IFNλ receptor to the subject and determining the effect of administering activator of IFNλ receptor to the subject on the obesity-related disorder, atherosclerosis or the coagulation disorder, wherein the activator of the IFNλ receptor is an IFNλ polypeptide or a polynucleotide encoding the IFNλ polypeptide, and wherein the IFNλ polypeptide is a type III IFN.
