The Study of the Use of Nintedanib in Slowing Lung Disease in Patients With Fibrotic or Non-Fibrotic Interstitial Lung Disease Related to COVID-19 (ENDCOV-I)

Early Nintedanib Deployment in COVID-19 Interstitial Lung Disease

This is a collaborative study between Icahn School of Medicine at Mount Sinai, Boehringer Ingelheim Pharmaceuticals and up to 9 other clinical centers across the US to determine the effect of nintedanib on slowing the rate of lung disease in patients who have been diagnosed with COVID-19, and have ongoing lung injury more than 30 days out from their diagnosis. Required one of the following after diagnosis with SARS-CoV-2: supplemental oxygen by nasal cannula, high flow oxygen, non invasive ventilation such as CPAP or BIPAP, or mechanical ventilation or a history of desaturation below 90%.

Study Overview

• Status: Completed
• Conditions: Pulmonary Fibrosis; Interstitial Lung Disease; Respiratory Disease
• Intervention / Treatment: Drug: Nintedanib; Drug: Placebo

Detailed Description

The purpose of this study is to determine the efficacy of the study drug, nintedanib, on slowing the rate of lung disease in patients who are noted to have infiltrates, or ongoing lung injury, on chest x-ray/CT 30 days or longer from their initial symptoms. In addition, the study will also investigate patient reported outcomes using questionnaires, and the safety and tolerability of the study drug. Blood specimens will be collected to assess biomarkers and monitor drug safety.

The trial will be randomized 1:1 between nintedanib and placebo.

Nintedanib has been approved by the FDA for the treatment of chronic fibrosing ILD with a progressive phenotype, but has not been studied in patients with post COVID 19 lung disease.

Subjects participating in this study will:

• Attend in person visits to the study doctor's office on the date of enrollment, 15 days after enrollment, 45 days after enrollment, 90 days after enrollment, 135 days after enrollment, and 180 days after enrollment. If the participant is being enrolled in the study while hospitalized, the study doctor will travel to the hospital room. There will also be a follow-up phone call 30 days after finishing study drug.
• Undergo a HRCT (High-resolution computed tomography) scan of the chest within 6 weeks of enrollment, and then again at 180 days after enrollment.
• Have Pulmonary Function Tests within 14 days of enrollment, and then again 45, 90, 135 and 180 days after enrollment.
• Have a six-minute walk test at baseline, day 90 and day 180 after enrollment.
• Have blood drawn routinely while participating in this study (within 14 days of randomization, 15 days after starting medication, then again on day 45, 90, 135 and 180).
• Participants will not pay for physician visits, blood draws, breathing tests, CT scans or the medication for this study. Participants will receive a stipend to cover the transportation costs for your visits.

The main risks to participants are:

1. Common side effects include: nausea, vomiting, diarrhea, stomach discomfort
2. Loss of appetite and weight loss
3. Liver function abnormalities (blood work will be monitored periodic intervals at scheduled blood draws as listed above)
4. Slightly higher risk of bleeding
5. Slightly higher risk of blood clots that can form in the blood vessels that supply oxygen to vital organs such as the brain and heart
6. Kidney disease resulting in protein/and or albumin being lost through urine

Benefits from participation in this research include the possibility that nintedanib may slow down/prevent progression of lung fibrosis. If the lungs can heal without fibrosis, this may result in fewer symptoms of shortness of breath, cough and need for added oxygen.

Instead of participating in this research, subjects may choose to monitor their lung condition with their doctor or participate in another research study.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Forced Vital Capacity (FVC)	Change in Forced Vital Capacity (FVC) at 90 days as compared to baseline. Forced vital capacity (FVC) is the amount of air that can be forcibly exhaled from your lungs after taking the deepest breath possible, as measured by spirometry.	Baseline and Day 90

Data driven texture analysis (DTA) is a patented deep learning method to quantify lung fibrosis. DTA score is reported in percentage ranging from 0% to 100%. A minimally clinical important difference when comparing CT scans from the same subject is 4%. A higher percentage suggests worsening lung injury.	180 days
Change in St. George's Respiratory Questionnaire (SGRQ)	The Saint George's Respiratory Questionnaire (SGRQ) is a self-reported disease-specific, health-related quality of life (QOL) questionnaire. 50-item instrument. Scores range from 0 to 100, with higher scores indicating more limitations. Change in SGRQ at Day 180 as compared to baseline	Baseline and Day 180
Change in King's Brief Interstitial Lung Disease Questionnaire (KBILD)	The King's Brief Interstitial Lung Disease (KBILD) questionnaire is a self-administered, ILD-specific measure of health-related quality of life, comprising 15 items with three domains (Psychological (KBILD-P), Breathlessness and activities (KBILD-B), and Chest symptoms (KBILD-C)) combined in a total score (KBILD-T). The KBILD domain and total score ranges are 0-100; 100 represents best health status. Change in KBILD score at Day 180 as compared to baseline.	Baseline and Day 180
Change in Leicester Cough Questionnaire (LCQ)	The LCQ is a 19 item questionnaire that assesses cough-related QOL. It has 3 domains (physical, psychological and social). The domain scores range from 1-7 and total score range is 3-21 with a higher score indicating a better quality of life. Change in LCQ at Day 180 as compared to baseline	Baseline and Day 180
Short Form (SF) 36 Health Survey	The (36) Health Survey is a 36-item, patient-reported survey of patient health. The SF-36 is a measure of health status in 8 health domains: physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health. Raw scale scores range from 0 - 100, with higher scores indicating less disability. Scores are averaged and converted to T scores to two composites: Physical Health and Mental Health. T score is a conversion of scores to a standardized scale with a mean of 50 and a standard deviation of 10. A higher score indicates better health.	Day 180

Change in Functional Assessment of Chronic Illness Therapy- Fatigue (FACIT-F)	The FACIT-F is a 40-item measure that assesses self-reported fatigue and its impact upon daily activities and function. Questions are scored on a 5-point Likert scale. The total score range is from 0-52, with higher score indicating lower fatigue level. Change in FACIT-F at Day 180 as compared to baseline.	Baseline and Day 180
Change in Diffusing Capacity of the Lungs for Carbon Monoxide (DLCO)	Change in Diffusing Capacity of the Lungs for Carbon Monoxide (DLCO) at 180 days as compared to baseline. Diffusing Capacity of the Lungs for Carbon Monoxide (DLCO) measures the transfer of carbon monoxide from alveolar gas to hemoglobin in pulmonary capillary blood. DLCO is measured by having the patient fully inhale a low concentration of carbon monoxide and an inert tracer gas. The results of a lung diffusion test are given in a percentage of what is the expected DLCO to be (predicted value). Normal DLCO: Between 75% and 140% of the predicted value. Mildly reduced DLCO: 60% to 75% or the lower limit of normal (LLN) predicted value. Severely reduced DLCO: Less than 40% of the predicted value.	Baseline and Day 180
