E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the effect of pirfenidone and the safety profile in subjects who have presented severe SARS-COV2 pneumonia, after recovery from associated ARDS, and who present clinical-radiological signs of pulmonary fibrosis. The effect of pirfenidone will be measured after 6 months of treatment by: ● % change in FVC ● Radiological change in % of pulmonary fibrosis (Chest HRCT) |
Evaluar el efecto de pirfenidona y el perfil de seguridad en sujetos que han presentado neumonía SARS-COV2 severa, tras recuperarse del SDRA asociado, que presentan signos clínico-radiológicos de fibrosis pulmonar, comparado con placebo. El efecto positivo de pirfenidona se medirá tras 6 meses de tratamiento mediante: - % de cambio en CVF - Cambio radiológico en el % de fibrosis pulmonar (TACAR Tórax) |
|

E.5.2 | Secondary end point(s) |
o Semi-annual rate of change in % FVC o HRCT Chest Fibrotic Score. HRCT scans will be obtained with 1-mm collimation and a 1-mm slice thickness at 10-mm intervals from the lung apices to the bases with the patient in the supine position at full inspiration. Two observers, unaware of the clinical data and lung function of the patients, will evaluate the data independently. The fibrotic HRCT findings (reticulation, traction bronchiectasis, honeycombing) will be assessed in three (upper, middle and lower) zones of each lung. The extent of each HRCT finding will be determined by visually estimating the percentage of parenchymal involvement in each zone. The six zone scores will be averaged to determine the total score for each patient. The HRCT fibrosis score will be recorded at the initial diagnosis and after six months in a same manner, and an investigation regarding the chronological changes in these values will be conducted. The manual score of every anonymized HRCT scan will be checked in IDIBELL by using the CALIPER software for automatically calculating fibrotic HRCT score. o Incidence of drug-associated adverse events (nature, seriousness, severity, frequency, causality, clinical consequence and time since drug onset) including nausea, diarrhea, abdominal pain, vomiting, headache, hypertransaminasemia o discontinuation of treatment. o % of cases with progression of pulmonary fibrosis (decrease in FVC ≥ 10% and/or of DLCO ≥ 15% and/or appearance of honeycomb images on HRCT chest when previously there was none). o Exercise capacity (improvement in % oxygen saturation at the end of the 6-minute walk test or increase in meters walked greater than 50 meters) o Decreased oxygen requirement for physical activity o Improvement in quality of life (difference in final K-BILD score greater than 5) o Hospitalizations or urgent visits (to the Emergency Room or out-patient Hospital) of a respiratory cause (infection, exacerbation, post-COVID19 complications) o Lung transplant or death |
o Tasa de cambio en el % de CVF a los 6 meses del tratamiento o Puntuación fibrótica TACAR tórax. Las imágenes del TACAR torax se obtendrán con 1 mm de grosor en intervalos de 10 mm desde los ápex hasta las bases con el paciente en posición supino y máxima inspiración. Dos observadores, sin información clínica ni función respiratoria de los pacientes, evaluaran las imágenes de forma independiente. Los cambios fibróticos (engrosamiento reticular, bronquiolectasias de tracción, panalización) se evaluaran en tres zonas de cada pulmón (superior, medio e inferior). La extensión de cada hallazgo radiológico será estimado en porcentaje visualmente con respecto a la zona parenquimatosa de cada área analizada. La media de las seis áreas determinará el score total de fibrosis para cada paciente. El TACAR tórax realizado a los 6 meses se analizará de la misma forma y se realizará el análisis de los cambios en cada área escrutada. Este cálculo manual se correlacionará al final del estudio con el cálculo automático a través del sistema CALIPER (en IDIBELL) a partir de los CD anonimizados recibidos de cada paciente incluido. o Incidencia de efectos adversos asociados al fármaco (naturaleza, gravedad, frecuencia, causalidad, consecuencia clínica y tiempo desde inicio fármaco) incluyendo nausea, diarrea, dolor abdominal, vómito, cefalea, hipertransaminasemia. o Discontinuación del tratamiento o del estudio. o % de casos con progresión de fibrosis pulmonar (descenso de CVF ≥ 10% y/o de la DLCO ≥ 15% y/o aparición de imágenes en panal en el TACAR tórax cuando previamente no existía). o Capacidad de ejercicio (mejora en % saturación de oxígeno al final de la prueba de caminata 6 minutos o incremento de los metros recorridos mayor a 50 metros) o Disminución del requerimiento de oxígeno para hacer actividad física o Mejora en la calidad de vida (diferencia en la puntuación final del K-BILD mayor de 5) o Hospitalizaciones o visitas urgentes (a Urgencias o Hospital de Día) de causa respiratoria (infección, agudización, complicaciones post-COVID19) o Transplante pulmonar o muerte |
