Abstract
The present invention relates to the use of enfumafungin derivative triterpenoid antifungal compounds in combination with other antifungal agents such azoles, polyenes, lipopeptides, and allylamides to treat fungal diseases. More particularly, the invention relates to antifungal combinations of enfumafungin derivative triterpenoids which are inhibitors of (1,3)-β-D-glucan synthesis, in combination with other antifungal agents such as mold-active agents that have activity against molds, including but not limited to voriconazole, isavuconazole, posaconazole, itraconazole and amphotericin B, for the treatment and/or prevention of infections caused by molds.
Claims14

- (a) a first therapeutic agent that is a compound of Formula (II):
- which is (1S,4aR,6aS,7R,8R,10aR,10bR,12aR,14R,15R)-15-[[2-amino-2,3,3-trimethylbutyl]oxy]-8-[(1R)-1,2-dimethylpropyl]-14-[5-(4-pyridinyl)-1H-1,2,4-triazol-1-yl]-1,6,6a,7,8,9,10,10a,10b,11,12,12a-dodecahydro-1,6a,8,10a-tetramethyl-4H-1,4a-propano-2H-phenanthro[1,2-c]pyran-7-carboxylic acid,
- or a pharmaceutically acceptable salt thereof;
- and
- (b) a second therapeutic agent that is isavuconazole,
- wherein the first therapeutic agent is administered orally at a dose of 50 mg to 1000 mg, and the second therapeutic agent is administered at a dose of 50 mg to 1000 mg, and
- wherein the dose of the first therapeutic agent and the dose of the second therapeutic agent are each administered at least once or twice per day for at least one week.
A method of treating an Aspergillus infection in a subject in need thereof, the method comprising administering to the subject:
- (a) a first therapeutic agent that is a compound of Formula (IIa):
- which is (1S,4aR,6aS,7R,8R,10aR,10bR,12aR,14R,15R)-15-[[2-amino-2,3,3-trimethylbutyl]oxy]-8-[(1R)-1,2-dimethylpropyl]-14-[5-(4-pyridinyl)-1H-1,2,4-triazol-1-yl]-1,6,6a,7,8,9,10,10a,10b,11,12,12a-dodecahydro-1,6a,8,10a-tetramethyl-4H-1,4a-propano-2H-phenanthro[1,2-c]pyran-7-carboxylicacid,
- or a pharmaceutically acceptable salt thereof;
- and
- (b) a second therapeutic agent that is isavuconazole,
- wherein the first therapeutic agent is administered orally at a dose of 50 mg to 1000 mg, and the second therapeutic agent is administered at a dose of 50 mg to 1000 mg, and
- wherein the dose of the first therapeutic agent and the dose of the second therapeutic agent are each administered at least once or twice per day for at least one week.
A method of preventing pulmonary aspergillosis in a subject in need thereof, the method comprising administering to the subject:
- (a) a first therapeutic agent that is a compound of Formula (IIa):
- which is (1S,4aR,6aS,7R,8R,10aR,10bR,12aR,14R,15R)-15-[[2-amino-2,3,3-trimethylbutyl]oxy]-8-[(1R)-1,2-dimethylpropyl]-14-[5-(4-pyridinyl)-1H-1,2,4-triazol-1-yl]-1,6,6a,7,8,9,10,10a,10b,11,12,12a-dodecahydro-1,6a,8,10a-tetramethyl-4H-1,4a-propano-2H-phenanthro[1,2-c]pyran-7-carboxylic acid,
- or a pharmaceutically acceptable salt thereof, and
- (b) a second therapeutic agent that is isavuconazole,
- wherein the first therapeutic agent is administered orally at a dose of 50 mg to 1000 mg, and the second therapeutic agent is administered at a dose of 50 mg to 1000 mg, and
- wherein the dose of the first therapeutic agent and the dose of the second therapeutic agent are each administered at least once or twice per day for at least one week.
A method of treating an Aspergillus infection in a subject in need thereof, the method comprising administering to the subject:
- (a) a first therapeutic agent that is a compound of Formula (IIa):
- which is (1S,4aR,6aS,7R,8R,10aR,10bR,12aR,14R,15R)-15-[[2-amino-2,3,3-trimethylbutyl]oxy]-8-[(1R)-1,2-dimethylpropyl]-14-[5-(4-pyridinyl)-1H-1,2,4-triazol-1-yl]-1,6,6a,7,8,9,10,10a,10b,11,12,12a-dodecahydro-1,6a,8,10a-tetramethyl-4H-1,4a-propano-2H-phenanthro[1,2-c]pyran-7-carboxylicacid,
- or a pharmaceutically acceptable salt thereof;
- and
- (b) a second therapeutic agent that is isavuconazole,
- wherein the first therapeutic agent and the second therapeutic agent are each administered in an amount effective to increase survival compared to the survival resulting from the administration of the first therapeutic agent in the absence of the second therapeutic agent or the administration of the second therapeutic agent in the absence of the first therapeutic agent.
A method of treating an Aspergillus infection in a subject in need thereof, the method comprising administering to the subject a pharmaceutical combination of:
- (a) a first therapeutic agent that is a compound of Formula (IIa):
- which is (1S,4aR,6aS,7R,8R,10aR,10bR,12aR,14R,15R)-15-[[2-amino-2,3,3-trimethylbutyl]oxy]-8-[(1R)-1,2-dimethylpropyl]-14-[5-(4-pyridinyl)-1H-1,2,4-triazol-1-yl]-1,6,6a,7,8,9,10,10a,10b,11,12,12a-dodecahydro-1,6a,8,10a-tetramethyl-4H-1,4a-propano-2H-phenanthro[1,2-c]pyran-7-carboxylicacid,
