Title:	Methods for treating antipsychotic-induced weight gain
Abstract:	The present invention relates to the discovery of a novel opioid modulator effective in reducing pharmacologically induced weight gain associated with atypical antipsychotic use. The present invention provides methods of reducing antipsychotic induced weight gain, methods for suppressing food intake and reducing ghrelin levels induced by atypical antipsychotic medications in a patient.
Inventor(s):	Daniel Deaver, Mark Todtenkopf
Assignee:	Alkermes Pharma Ireland Ltd
Application Number:	US16/390,531
Patent Claims:	1. A method of reducing antipsychotic induced weight gain comprising administering to the patient in need of treatment an effective amount of a composition comprising an atypical antipsychotic and a compound of Formula I or pharmaceutically acceptable salt thereof, wherein, A is chosen from —C(═O)NH2 and —C(═S)NH2; R1 and R2 are both hydrogen or taken together R1 and R2 are ═O; R3 is chosen from hydrogen, alkyl, alkenyl, aryl, heterocyclyl and hydroxyalkyl; R4 is chosen from hydrogen, hydroxy, amino, alkoxy, C1-C20 alkyl and C1-C20 alkyl substituted with hydroxy or carbonyl; R5 is selected from hydrogen, hydroxyl, alkoxy and alkyl; R6 is chosen from hydrogen, hydroxy, alkoxy and —NR10R11; or together, R5 and R6 form a carbonyl or a vinyl substituent; R10 and R11 are chosen independently from hydrogen and alkyl and aliphatic; and, represents a single or double bond. 2. The method according to claim 1, wherein said compound of Formula I is selected from a compound of Formula II or a pharmaceutically acceptable salt thereof, wherein, R3, R4, R5, and R6 are as defined above. 3. The method according to claim 2, wherein R4 is selected from hydrogen and hydroxyl; R5 is selected from hydrogen, and hydroxyl; and R6 is hydrogen; or together, R5 and R6 form a carbonyl or a vinyl substituent. 4. The method of claim 2, wherein R4 is hydroxyl; and together, R5 and R6 form a carbonyl substituent. 5. The method according to claim 1, wherein an increased appetite is induced by administration of an atypical antipsychotic. 6. The method according to claim 1, wherein the atypical antipsychotic is selected from olanzapine, clozapine, risperidone, quetiapine, aripiprazole, ziprasidone, and pharmaceutically acceptable salts thereof. 7. The method of claim 1, wherein said compound of Formula I is administered in a daily dose of about 3 mg/day to about 30 mg/day. 8. The method according to claim 1, wherein said composition is in the form of a tablet. 9. The method of claim 8, wherein R4 is hydroxyl; and together, R5 and R6 form a carbonyl substituent. 10. The method according to claim 1, wherein R4 is selected from hydrogen and hydroxyl; R5 is selected from hydrogen, and hydroxyl; and R6 is hydrogen; or together, R5 and R6 form a carbonyl or a vinyl substituent. 11. The method of claim 10, wherein R4 is hydroxyl; and together, R5 and R6 form a carbonyl substituent. 12. The method of claim 1, wherein R4 is hydroxyl; and together, R5 and R6 form a carbonyl substituent. 13. The method according to claim 1, wherein R3 is selected from, hydrogen, cyclopropyl, cyclobutyl, vinyl, furan and tetrahydrofuran. 14. The method according to claim 1, wherein said compound of Formula I is selected from: or a pharmaceutically acceptable salt thereof. 15. The method according to claim 14, wherein the compound is: or a pharmaceutically acceptable salt thereof.
