At present, investigators have a very limited view on the long-term pulmonary sequelae after COVID-19 pneumonia, particularly in the most severe forms requiring hospitalization. Early thoracic HRCT is a useful tool for the evaluation of patients suspected of COVID-19 pneumonia. Typical features are evocative of the disease in an epidemic context, with multifocal ground-glass opacities, being nodular or not, or crazy-paving with or without consolidations, with a bilateral, peripheral or mixed distribution and involvement of the posterior zones. CT manifestations of fibrosis or fibrous stripes are described in COVID-19. Pan et al observed fibrous stripes in 17% patients in the early phase of the disease. Ye et al observed bronchiectasis in 2 patients (15.4%) and evidence of pulmonary fibrosis in 3 patients (23.7%) at HRCT performed at 4 weeks. Long term data are still lacking in patients with COVID-19 and the investigators do not know how many patients will have fibrotic sequelae from the acute illness.

Arms

Experimental: Nintedanib

Experimental group will receive nintedanib 150mg BID for 12 months in addition to standard of care (SoC). Nintedanib dose could be reduced to 100mg BID depending on tolerance according to investigator in charge of the patient. The prescription of SoC drugs or procedure will be let to the choice of the investigator in charge of the patient.

Placebo Comparator: Placebo

Control group will receive Placebo BID for 12 months in addition to SoC. The prescription of SoC drugs or procedure will be let to the choice of the investigator in charge of the patient. Standard of care may include pulmonary rehabilitation.
