## Abstract

The present invention relates to a composition for use in the treatment of a disease or disorder, wherein said disease or disorder is preferably a disease or disorder in which aldosterone overexposure contributes to the symptoms of said disease or disorder, said composition comprises a compound which is (R)-(+)-5-(p-cyanophenyl)-5,6,7,8-tetrahydroimidazo[1,5-a]pyridine or a pharmaceutically acceptable salt thereof, wherein preferably said compound is (R)-(+)-5-(p-cyanophenyl)-5,6,7,8-tetrahydroimidazolium[1,5-a]pyridine dihydrogen phosphate, and wherein said compound has an enantiomeric excess (ee) of the (R) form higher than or equal to 97%, and wherein said composition is administered once daily to a subject in need thereof. The invention further relates to a pharmaceutical composition comprising a daily dosage of said compound in a fixed-unit dosage form and to a combination comprising (i) said pharmaceutical composition or said compound; and (ii) instructions for administration of said pharmaceutical composition or said compound once per day.

## Claims

### Claim 1

A method of treating a disease or disorder selected from primary aldosteronism and secondary aldosteronism in human a subject in need thereof, the method comprising orally administering once daily to said subject a therapeutically effective amount of a composition comprising 4 mg or 8 mg of a compound which is R)-(+)-5-(p-cyanophenyl)-5,6,7,8-tetrahydroimidazo[1,5-a]pyridine dihydrogen phosphate, wherein said compound has an enantiomeric excess (ee) of the (R) form higher than or equal to 99%.

### Claim 2 (depends on 1)

The method according to claim 1, wherein an elimination half-life (T1/2) of said compound upon administration of one 4mg or 8mg daily dose to the subject is longer than 8h, as measured in a blood sample of the subject obtained at 8, 12, 16 or 24 hours post-dose.

### Claim 3 (depends on 1)

The method according to claim 1, wherein said (R)-(+)-5-(p-cyanophenyl)-5,6,7,8-tetrahydroimidazolium[1,5-a]pyridine dihydrogen phosphate is a crystalline form I of (R)-(+)-5-(p-cyanophenyl)-5,6,7,8-tetrahydroimidazolium [1,5-a]pyridine dihydrogen phosphate, wherein said crystalline form I has an X-ray powder diffraction pattern comprising the following 20 values measured using CuKα radiation: 19.504; 21.919 and 24.159, wherein each peak may vary by ±0.5.

### Claim 4 (depends on 1)

The method according to claim 1, wherein said disease or disorder is primary aldosteronism.

### Claim 5 (depends on 1)

The method of claim 1, wherein said disease or disorder is secondary aldosteronism.

### Claim 6 (depends on 1)

The method according to claim 1, wherein said compound has an enantiomeric excess (ee) of the (R) form higher than or equal to 99.5%.

### Claim 7 (depends on 1)

The method according to claim 1, wherein said compound has an enantiomeric excess (ee) of the (R) form higher than or equal to 99.8%.

### Claim 8 (depends on 1)

The method according to claim 1, wherein said compound has an enantiomeric excess (ee) of the (R) form higher than or equal to 99.9%.

### Claim 9 (depends on 1)

The method according to claim 1, wherein said disease or disorder is primary aldosteronism, and wherein said composition comprises 8 mg of the compound.

### Claim 10 (depends on 1)

The method according to claim 1, wherein said disease or disorder is secondary aldosteronism, and wherein said composition comprises 8 mg of the compound.

### Claim 11 (depends on 1)

The method according to claim 1, wherein said disease or disorder is primary aldosteronism, and wherein said composition comprises 4 mg of the compound.

### Claim 12 (depends on 1)

The method according to claim 1, wherein said disease or disorder is secondary aldosteronism, and wherein said composition comprises 4 mg of the compound.

### Claim 13

A method of treating primary aldosteronism in a human subject in need thereof, the method comprising orally administering to the subject 4 mg of the compound (R)-(+)-5-(p-cyanophenyl)-5,6,7,8-tetrahydroimidazolium[1,5-a]pyridine dihydrogen phosphate, once daily, wherein said compound has an enantiomeric excess (ee) of the (R) form higher than or equal to 99%.

### Claim 14

A method of treating primary aldosteronism in a human subject in need thereof, the method comprising orally administering to the subject 8 mg of the compound (R)-(+)-5-(p-cyanophenyl)-5,6,7,8-tetrahydroimidazolium[1,5-a]pyridine dihydrogen phosphate, once daily, wherein said compound has an enantiomeric excess (ee) of the (R) form higher than or equal to 99%.

### Claim 15 (depends on 13)

The method of claim 13, wherein the human subject is a pediatric patient.

### Claim 16 (depends on 13)

The method of claim 13, wherein the human subject is a woman of child bearing potential.

### Claim 17 (depends on 14)

The method of claim 14, wherein the human subject is a pediatric patient.
