Title:Methods of administering pirfenidone therapy
Abstract: The disclosure relates to improved methods of administering pirfenidone therapy when ciprofloxacin is administered concomitantly.
Inventor(s): Bradford; Williamson Z. (Wilson, WY)
Assignee: Intermune, Inc. (Brisbane, CA)
Application Number:14/015,857
Patent Claims: 1. An improved method of administering pirfenidone therapy to treat a patient suffering from a fibrotic disorder, inflammatory disorder, or autoimmune disorder comprising reducing the dosage of pirfenidone administered to the patient by about one-half to about one-third during concomitant administration of ciprofloxacin at a dose of 750 mg twice daily (1500 mg/day).

2. A method of administering pirfenidone therapy to treat a patient suffering from a fibrotic disorder, inflammatory disorder, or autoimmune disorder, comprising administering to the patient a therapeutically effective amount of pirfenidone, and avoiding concomitant administration of ciprofloxacin at a dose of 750 mg.

3. The method of claim 1 wherein the pirfenidone dosage is reduced from about 2403 mg/day to a dosage ranging from about 1400 mg/day to about 1650 mg/day, optionally 1602 mg/day, during ciprofloxacin administration.

4. The method of claim 1 wherein the pirfenidone dosage is reduced from about 1800 mg/day to a dosage ranging from about 1000 mg/day to about 1250 mg/day, optionally 1200 mg/day, during ciprofloxacin administration.

5. The method of claim 1 wherein the method is for avoiding the potential for a reduced clearance of pirfenidone or the potential for an increased exposure to pirfenidone.

6. The pirfenidone of claim 1 wherein the total daily dose of pirfenidone is administered to the patient in divided doses three times per day, with food.

7. The method of claim 1 wherein the pirfenidone is administered in unit dosage forms that are capsules or tablets.

8. The method of claim 7 wherein the amount of pirfenidone in the unit dosage form is 200 mg or 267 mg.

9. The method of claim 1 wherein during concomitant ciprofloxacin administration 534 mg of pirfenidone is administered to the patient three times per day, with food.

10. The method of claim 1 wherein during the concomitant administration of ciprofloxacin the pirfenidone is administered at a total daily dosage of 1602 mg.

11. The method of claim 1 wherein during concomitant ciprofloxacin administration the pirfenidone is administered at a total daily dosage of about 1600 mg.

12. The method of claim 1 wherein the patient has idiopathic pulmonary fibrosis (IPF).

13. An improved method of administering pirfenidone therapy to treat a patient comprising reducing the dosage of pirfenidone administered to the patient by about one-half to about one-third during concomitant administration of ciprofloxacin at a dose of 750 mg twice daily (1500 mg/day), wherein the patient suffers from a disease selected from idiopathic pulmonary fibrosis, pulmonary fibrosis, bronchiolitis obliterans, chronic lung transplant rejection, scleroderma, primary focal segmental glomerulosclerosis (FSGC) or membranoproliferative glomerulonephritis (MPGN), idiopathic interstitial pneumonia, interstitial lung disease in systemic sclerosis, a fibrosis condition of the lung, autoimmune lung diseases, benign prostate hypertrophy, coronary or myocardial infarction, atrial fibrillation, cerebral infarction, myocardiac fibrosis, musculoskeletal fibrosis, post-surgical adhesions, liver cirrhosis, renal fibrotic disease, fibrotic vascular disease, Hermansky-Pudlak syndrome, neurofibromatosis, diabetic retinopathy, skin lesions, lymph node fibrosis associated with HIV, chronic obstructive pulmonary disease (COPD), inflammatory pulmonary fibrosis, rheumatoid arthritis; rheumatoid spondylitis; osteoarthritis; gout; sepsis; septic shock; endotoxic shock; gram-negative sepsis; toxic shock syndrome; myofacial pain syndrome (MPS); Shigellosis; asthma; adult respiratory distress syndrome; inflammatory bowel disease; Crohn's disease; psoriasis; eczema; ulcerative colitis; glomerular nephritis; chronic thyroiditis; Grave's disease; Ormond's disease; autoimmune gastritis; myasthenia gravis; autoimmune hemolytic anemia; autoimmune neutropenia; thrombocytopenia; pancreatic fibrosis; chronic active hepatitis, hepatic fibrosis; acute or chronic renal disease; renal fibrosis; diabetic nephropathy; irritable bowel syndrome; pyresis; restenosis; cerebral malaria; stroke or ischemic injury; neural trauma; Huntington's disease; Parkinson's disease; acute or chronic pain; allergic rhinitis, allergic conjunctivitis; cardiac hypertrophy, chronic heart failure; acute coronary syndrome; cachexia; malaria; leprosy; leishmaniasis; Lyme disease; Reiter's syndrome; acute synoviitis; muscle degeneration, bursitis; tendonitis; tenosynoviitis; herniated, ruptured, or prolapsed intervertebral disk syndrome; osteopetrosis; thrombosis; silicosis; pulmonary sarcosis; bone resorption diseases, osteoporosis, multiple myeloma-related bone disorders; metastatic breast carcinoma, colorectal carcinoma, graft-versus-host reaction; multiple sclerosis, lupus, fibromyalgia; AIDS, viral diseases, Herpes Zoster, Herpes Simplex I or II, influenza virus, Severe Acute Respiratory Syndrome (SARS) cytomegalovirus; diabetes mellitus, acute myelogenous leukemia, chronic myelogenous leukemia, Kaposi's sarcoma, metastatic melanoma, multiple myeloma, breast cancer, colorectal carcinoma; gastric cancer; non-small cell lung cancer (NSCLC); bone metastases; neuromuscular pain, headache, cancer pain, dental pain, or arthritis pain; solid tumor angiogenesis, ocular neovascularization, infantile hemangioma; organ hypoxia; thrombin-induced platelet aggregation; or protozoal diseases.

14. The method of claim 10 wherein the patient has idiopathic pulmonary fibrosis (IPF).

15. The method of claim 10 wherein the patient suffers from a disease selected from idiopathic pulmonary fibrosis, pulmonary fibrosis, bronchiolitis obliterans, chronic lung transplant rejection, scleroderma, primary focal segmental glomerulosclerosis (FSGC) or membranoproliferative glomerulonephritis (MPGN), idiopathic interstitial pneumonia, interstitial lung disease in systemic sclerosis, a fibrosis condition of the lung, myocardiac fibrosis, musculoskeletal fibrosis, post-surgical adhesions, renal fibrotic disease, fibrotic vascular disease, Hermansky-Pudlak syndrome, neurofibromatosis, lymph node fibrosis associated with HIV, inflammatory pulmonary fibrosis, pancreatic fibrosis; hepatic fibrosis; or renal fibrosis.

16. The method of claim 14 wherein the total daily dose of pirfenidone is administered to the patient in divided doses three times per day.

17. The method of claim 16 wherein the pirfenidone is administered with food.

18. The method of claim 13 wherein during concomitant ciprofloxacin administration the pirfenidone is administered at a total daily dosage of 1602 mg.
