Abstract
The present invention relates to crystalline forms of (3R,9S)-4-isopropyl-7,7-dimethyl-3-(4-(trifluoromethyl)phenyl)-2′,3′,5′,6,6′,7,8,9-octahydro-3H-spiro[furo[3,4-c]quinoline-1,4′-pyran]-9-ol and its hydrochloride or hydrobromide salts, to a process for the manufacture thereof, and to the use thereof in pharmaceutical compositions.
Claims24
A crystalline hydrochloride salt of (3R,9S)-4-isopropyl-7,7-dimethyl-3-(4-(trifluoromethyl)phenyl)-2′,3′,5′,6,6′,7,8,9-octahydro-3H-spiro[furo[3,4-c]quinoline-1,4′-pyran]-9-ol.
A crystalline hydrobromide salt of (3R,9S)-4-isopropyl-7,7-dimethyl-3-(4-(trifluoromethyl)phenyl)-2′,3′,5′,6,6′,7,8,9-octahydro-3H-spiro[furo[3,4-c]quinoline-1,4′-pyran]-9-ol.
A crystalline free base form of (3R,9S)-4-isopropyl-7,7-dimethyl-3-(4-(trifluoromethyl)phenyl)-2′,3′,5′,6,6′,7,8,9-octahydro-3H-spiro[furo[3,4-c]quinoline-1,4′-pyran]-9-ol.
Pharmaceutical composition comprising (3R,9S)-4-isopropyl-7,7-dimethyl-3-(4-(trifluoromethyl)phenyl)-2′,3′,5′,6,6′,7,8,9-octahydro-3H-spiro[furo[3,4-c]quinoline-1,4′-pyran]-9-ol as a crystalline free base form, a hydrochloride crystalline salt form or a hydrobromide salt form, optionally together with one or more inert carriers and/or diluents.
A method of using (3R,9S)-4-isopropyl-7,7-dimethyl-3-(4-(trifluoromethyl)phenyl)-2′,3′,5′,6,6′,7,8,9-octahydro-3H-spiro[furo[3,4-c]quinoline-1,4′-pyran]-9-ol as a crystalline free base form, a hydrochloride crystalline salt form or a hydrobromide salt form for treating or preventing diseases, disorders or conditions which can be influenced by inhibiting the cholesterol ester transfer protein (CETP), optionally in combination with one or more other therapeutic agents.
A method for treating or preventing diseases, disorders or conditions which can be influenced by inhibiting the cholesterol ester transfer protein (CETP), the method comprising administering to a patient in need thereof a hydrochloride crystalline salt form of (3R,9S)-4-isopropyl-7,7-dimethyl-3-(4-(trifluoromethyl)phenyl)-2′,3′,5′,6,6′,7,8,9-octahydro-3H-spiro[furo[3,4-c]quinoline-1,4′-pyran]-9-ol.
A process for preparing a pharmaceutical composition comprising (3R,9S)-4-isopropyl-7,7-dimethyl-3-(4-(trifluoromethyl)phenyl)-2′,3′,5′,6,6′,7,8,9-octahydro-3H-spiro[furo[3,4-c]quinoline-1,4′-pyran]-9-ol as a crystalline free base form, a hydrochloride crystalline salt form or a hydrobromide crystalline salt form, the process comprising combining or mixing said free base form, said hydrochloride salt form, or said hydrobromide salt form of (3R,9S)-4-isopropyl-7,7-dimethyl-3-(4-(trifluoromethyl)phenyl)-2′,3′,5′,6,6′,7,8,9-octahydro-3H-spiro[furo[3,4-c]quinoline-1,4′-pyran]-9-ol, and one or more inert carriers and/or diluents.
