Pharmaceutical compositions of nilotinib
Amorphous solid dispersions of nilotinib fumarate or nilotinib tartrate are provided, as well as pharmaceutical compositions thereof, wherein the compositions exhibit enhanced bioavailability in the fasted state. Preferably, the compositions may be orally administered to a patient in either the fed or fasted state, with a decrease or elimination of the food effect. Preferably, following oral administration of the pharmaceutical compositions, there is no substantial difference in the pharmacokinetic parameters (e.g., C max , AUC 0-t and/or AUC 0-infinity ) of nilotinib, regardless of whether the pharmaceutical compositions are administered to a subject in the fed or fasted state.
1 . A pharmaceutical composition comprises:
(i) nilotinib or a pharmaceutical acceptable salt thereof in an amount equivalent to about 75 mg of nilotinib free base;
(ii) a pharmaceutically acceptable carrier comprising hydroxypropyl methyl cellulose acetate succinate (HPMC-AS), polyvinyl pyrrolidine and vinyl acetate (PVP/VA) copolymer, hydroxypropyl methylcellulose phthalate (HPMCP), hydroxypropyl methylcellulose, (HPMC), polyethylene glycol (PEG), hydroxypropyl cellulose (HPC), carboxymethyl cellulose (CMC), polyvinyl pyrrolidine (PVP), or combinations thereof; and
(iii) optionally one or more pharmaceutically acceptable excipients;
wherein administration of said composition under fasting condition results in an enhancement of at least 100% in bioavailability compared to that of a reference formulation administered under fasting conditions.
2 . A pharmaceutical composition comprises:
(i) nilotinib or a pharmaceutical acceptable salt thereof in an amount equivalent to about 100 mg of nilotinib free base;
(ii) a pharmaceutically acceptable carrier comprising hydroxypropyl methyl cellulose acetate succinate (HPMC-AS), polyvinyl pyrrolidine and vinyl acetate (PVP/VA) copolymer, hydroxypropyl methylcellulose phthalate (HPMCP), hydroxypropyl methylcellulose, (HPMC), polyethylene glycol (PEG), hydroxypropyl cellulose (HPC), carboxymethyl cellulose (CMC), polyvinyl pyrrolidine (PVP), or combinations thereof; and
(iii) optionally one or more pharmaceutically acceptable excipients;
wherein administration of said composition under fasting condition results in an enhancement of at least 100% in bioavailability compared to that of a reference formulation administered under fasting conditions.
3 . The pharmaceutical composition according to claim 1 , wherein the one or more pharmaceutically acceptable excipients are present, and comprise one or more diluents, binders, disintegrants, lubricants, glidants, surfactants, solubilizers, plasticizers, stabilizing agents, antioxidants or combinations thereof.
4 . The pharmaceutical composition according to claim 1 , wherein the pharmaceutically acceptable carrier is hydroxy propyl methyl cellulose acetyl succinate (HPMC-AS).
5 . The pharmaceutical composition according to claim 1 , wherein the nilotinib is present as nilotinib tartrate, and a weight ratio of the nilotinib tartrate to the pharmaceutically acceptable carrier is from about 1:6 to about 1:1.
6 . The pharmaceutical composition according to claim 1 , wherein the nilotinib or a pharmaceutical acceptable salt thereof is selected from nilotinib tartrate or nilotinib fumarate.
7 . The pharmaceutical composition according to claim 6 , wherein an amount of nilotinib in a unit dosage form is about 90 mg to about 200 mg of nilotinib fumarate or nilotinib tartrate.
8 . The pharmaceutical composition according to claim 1 , wherein the pharmaceutical composition is in the form of a tablet, a capsule, a caplet, beads, granules or an oral suspension.
