NORCOVID: Oral Prednisone Regimens to Optimize the Therapeutic Strategy in Patients With Organizing Pneumonia Post-COVID-19
Study Details
Study Description
Brief Summary
Background: Based on data from the 2003 SARS-COVID pandemic, other serious lung infections, and patients with respiratory distress, it is estimated that 10-30% of patients with severe SARS-COVID-2 pneumonia may present as a sequel an organized pneumonia. The treatment of this complication is not well defined. The use of oral corticosteroids is mandatory to avoid a possible evolution to pulmonary fibrosis, however, the doses to be administered and the duration of treatment are unknown as there is no study specifically aimed at solving this doubt. Many authors advocate high-dose treatment regimens for a minimum of six months, as proposed for cryptogenic organized pneumonia. However, there is a question whether in non-idiopathic cases of organized pneumonia, less intense treatment could resolve the disease. Hypothesis: The use of a less intensive prednisone regimen may be sufficient for therapeutic control in patients with post-COVID-19 organizing pneumonia, in relation to the established standard regimen Simplicity of the procedures: The objective of the NORCOVID study is to identify the optimal treatment regimen with corticosteroids in post-COVID19 patients diagnosed with NO. Specifically, the primary objective of this multicenter randomized trial is to evaluate whether treatment with a less intensive regimen of corticosteroids produces a non-inferior therapeutic effect than the established control regimen. Secondary objectives are to evaluate the effect of treatment on secondary efficacy variables and on safety. DLCO, respiratory function tests, 6MWT test, need for rescue, radiological tests, complications, mortality and the WHO ordinal scale will be evaluated.

Detailed Description
Hypothesis The use of a less intensive prednisone regimen may be sufficient for therapeutic control in patients with post-COVID-19 organizing pneumonia, in relation to the established standard regimen.
Objectives The objective of the NORCOVID study is to identify the optimal treatment regimen with corticosteroids in post-COVID19 patients diagnosed with NO. Specifically, the primary objective of this multicenter randomized trial is to evaluate whether treatment with a less intensive regimen of corticosteroids produces a non-inferior therapeutic effect than the established control regimen. Secondary objectives are to evaluate the effect of treatment on secondary efficacy variables and on safety. DLCO, respiratory function tests, 6MWT test, need for rescue, radiological tests, complications, mortality and the WHO ordinal scale will be evaluated.

Products evaluated and administration regimens.
The product evaluated will be Prednisone orally in two administration schedules:
-
Control Group: Prednisone 0.75mg / Kg / d 4week; 0.5mg / Kg / d 4 weeks; 20mg / d 4 weeks; 10mg / d 6 weeks; 5mg / d 6 weeks (6m).
-
Experimental Group: Prednisone 0.5mg / Kg / d 3 weeks, 20mg / day 3 weeks; 15mg / day 2 weeks; 10mg / day 2 weeks, 5mg / day 2 weeks and discontinue.
Main variable - The main variable will be the change in pulmonary diffusion, in terms of predicted DLCO (%), between the baseline value and that obtained at 6 months, comparing the two treatment groups adjusting for the baseline value using a model of Repeated measures with random effects (mixed model for repeated measurements: MMRM).
Secondary variables
-
DLCO in original units (DLCO10s mLmin - 1mmHg - 1)
-
Percentage of patients with values <80% predicted
-
Respiratory function tests
-
6-Minute-Walk Test (6MWT) test
-
Need for rescue
-
Computed Axial Tomography Test
-
Complications related to the evolution of the disease (serious and non-serious)
-
Complications related to corticosteroid treatment (serious and non-serious)
-
Complication of any kind (serious and non-serious)
-
Mortality from any cause
-
Ordinal variable of clinical improvement recommended by the WHO R&D Blueprint expert group15 for the acute phase. The worst score obtained during the study will be evaluated at each visit and as a summary measure.
