1-45. (canceled)
Desidustat particles, wherein at least 90% of the desidustat particles are less than about 250 μm.
Desidustat particles, wherein
- at least 90% of the desidustat particles are less than about 175 μm,
- at least 50% of the desidustat particles are less than about 75 μm, and
- at least 10% of the desidustat particles are less than about 10 μm.
Desidustat particles having specific surface area value of at least 0.75 m2/g.
A pharmaceutical composition comprising a therapeutically effective amount of desidustat particles and at least one pharmaceutically acceptable excipient, wherein at least 90% of the desidustat particles are less than about 250 μm, and wherein the composition provides a serum or plasma profile for desidustat comprising:
- (i) a mean of Cmax of from about 1,500 ng/ml to about 15,000 ng/ml, when administered to a patient in need thereof, or
- (ii) a mean of AUClast of from about 10,000 hr*ng/ml to about 75,000 hr*ng/ml, when administered to a patient in need thereof, or
- (iii) a Tmax of from about 0.5 hr to about 7.0 hr, when administered to a patient in need thereof.
A pharmaceutical composition comprising a therapeutically effective amount of desidustat particles and at least one pharmaceutically acceptable excipient, wherein at least 90% of the desidustat particles are less than about 250 μm, and wherein the composition does not contain 1-(but-3-en-1-yloxy)-4-hydroxy-2-oxo-1,2-dihydroquinoline-3-carbonyl) glycine more than 0.5% by weight of desidustat, as measured by HPLC, after storage for 3 months at 40°±2° C. and 75±5% relative humidity.
A pharmaceutical composition comprising a therapeutically effective amount of desidustat particles and at least one pharmaceutically acceptable excipient, wherein at least 90% of the desidustat particles are less than about 250 μm, and wherein the composition retains at least 95% of the desidustat after storage for 3 months at 40°±2° C. and 75±5% relative humidity.
A pharmaceutical composition comprising:
- (i) from 30 to 45% by weight of desidustat particles, wherein at least 90% of the desidustat particles are less than about 250 μm;
- (ii) from 30 to 55% by weight of a diluent selected from microcrystalline cellulose, lactose, starch or mannitol;
- (iii) from 3 to 7% by weight of a disintegrant selected from croscarmellose sodium, crospovidone, pregelatinized starch, sodium starch glycolate or low-substituted hydroxypropyl cellulose;
- (iv) from 2 to 6% by weight of a binder selected from hydroxypropyl methylcellulose, polyvinylpyrrolidone or hydroxypropylcellulose;
- (v) from 0.5 to 3% by weight of a glidant;
- (vi) from 0.5 to 3% by weight of a lubricant;
- and
- (vii) an optional coating.
