IPF Clinical Trials Currently Enrolling STUDY COORDINATOR’S INFORMATION Candace Flaherty: [email protected], Pager # 37472, 734-936-8301 Cough Study (HUM 104112) Needed: Patients with ILD and a persistent cough for at least 8 weeks. AF-219 is a P2X3 receptor being studied as potential tx for cough. Purpose is looking at potential side effects and efficacy when taken BID compared to placebo. Crossover study design, so patient will be on placebo for 2 weeks, and study drug for 2 weeks. Inclusion Diagnosis of IPF by HRCT or SLB and stable for 4 weeks Self-reported history of troublesome daily cough weeks (if asked on scale of 1-100, should be >40 self- reported to determine if VAS is eligible) Exclusion Current smoker Beginning of treatment with an ACE-inhibitor (which treats high blood pressure) within 4 weeks prior to the Baseline Visit (Day 0) or during the study History of opioid use for treatment of cough within 1 week of the Baseline Visit Body mass index (BMI) <18 kg/m2 or ≥ 40 kg/m2 Recent history of stroke or TIA (within 6 months prior to Screening) Blood donation within 56 days or plasma donation within 7 days prior to dosing Any condition possibly affecting drug absorption (e.g., gastrectomy, gastroplasty, any type of bariatric surgery, vagotomy (surgery treating ulcer disease), or bowel resection) History of cutaneous adverse drug reaction to sulfonamides or signs and symptoms suggestive of anaphylaxis to sulfonamides An Exploratory Multicenter Open-label Single Arm Study of the Safety and Tolerability of Pirfendidone in Combination with Nintedanib in Patients with IPF (HUM 108398) Needed: Patients with mild to moderate ILD pirfenidone for at least 16 weeks and on stable dose for at least 28 days prior to screening willing to add nintedanib to treatment course. The expected study length is up to 21 months Inclusion Ages 40-80 inclusive Diagnosis of IPF by HRCT or SLB FVC ≥ 50% DLCO ≥ 30% Exclusion Evidence of active infection Lung txp anticipated in 12 months after start of screening Known hypersensitivity to the active substance or any excipient of either pirfenidone or nintedanib Any planned significant surgical intervention during time of study QtcF ≥ 500 ms at Screening Use of strong CYP1A2 inhibitors History of unstable cardiac or pulmonary disease in 6 months prior to screening; such as MI, CHF, uncontrolled clinically significant arrhythmias. Severe hepatic or renal impairment History or risk of GI tract perforation Use of any tobacco product in the 12 weeks before the start of Screening IPF PRO Registry (HUM 87132) Needed: Patients recently diagnosed (within 3 months from ILD conference date) returning to UM on a regular basis for follow up. Prospective registry will collect information regarding natural history, questionnaire data and blood samples for repository during scheduled return clinic visits. Inclusion Ages 40 or greater New diagnosis of IPF at ILD conference Exclusion Malignancy other than skin cancer with past 5 years Previously diagnosed at this site with IPF Currently listed for lung txp Currently enrolled in randomized clinical trial WRAP Study Criteria (HUM 81631) Needed: Patients diagnosed with IPF and evidence of abnormal acid gastro-esophageal reflux by 24-hour pH testing. Inclusion Confirmed IPF Abnormal GER on 24-hour pH monitoring and esophageal manometry Be willing to under laparoscopic anti-reflux surgery Exclusion FVC < 50% predicted FEV1/FVC ratio < 0.65 Resting room air PaO2 < 60mm Hg Unable to walk 50 meters on 6 minute walk test Recent acute respiratory illness in last 12 weeks Listed for lung transplantation at screening History of esophageal / bariatric / gastric surgery BMI > 35 Unlikely to obtain pre-authorized approval from a third party payer for laparoscopic anti-reflux surgery and related costs in the opinion of the investigators Known severe pulmonary hypertension History of cancer (other than non-melanoma skin cancer) in the last 3 years
