Pharmaceutical compositions and methods comprising a combination of a benzoxazole transthyretin stabilizer and an additional therapeutic agent
The present invention relates to pharmaceutical compositions and methods of treatment comprising administering to a patient in need thereof a combination of a benzoxazole derivative transthyretin stabilizer or a pharmaceutically acceptable salt or prodrug thereof and an additional therapeutic agent for the treatment of transthyretin amyloidosis. Particularly, the present invention relates to pharmaceutical compositions and methods of treatment comprising administering to a patient in need thereof 2-(3,5-dichlorophenyl)-1,3-benzoxazole-6-carboxylic acid or a pharmaceutically acceptable salt or prodrug thereof and one or more additional therapeutic agent for the treatment of transthyretin amyloidosis.
1. A method of treating TTR amyloidosis in a patient, the method comprising administering to a patient in need thereof a therapeutically effective amount of 2-(3,5-dichlorophenyl)-1,3-benzoxazole-6-carboxylic acid or a pharmaceutically acceptable salt thereof in combination with one or more additional therapeutic agents wherein the additional therapeutic agent is ataluren.
2. The method of claim 1 wherein ataluren is administered to the patient orally three times a day for a total dosage of approximately 40 mg/kg and tafamidis or a pharmaceutically acceptable salt thereof is administered to the patient orally once a day.
3. The method of claim 2 wherein 80 mg of tafamidis meglumine or 61 mg of tafamidis free acid is administered.
4. The method of claim 1 wherein ataluren and tafamidis meglumine or tafamidis free acid are administered to the patient together orally three times a day wherein the first and second doses comprise 10 mg/kg ataluren and either 20 mg tafamidis meglumine or 15.25 mg tafamidis free acid; and the third dose comprises either 40 mg tafamidis meglumine or 30.5 mg tafamidis free acid.
5. A method of inhibiting TTR fibril formation in a patient, the method comprising administering a therapeutically effective amount of ataluren or a pharmaceutically acceptable salt thereof to a patient.
