E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
- Part 1: To evaluate the proportion of patients achieving complete renal response with iptacopan treatment "A" plus standard of care, compared to treatment alone - Part 2: To evaluate the proportion of patients achieving complete renal response with Iptacopan treatment "B" plus standard of care, compared to treatment "D" alone - Part 2: To evaluate the proportion of patients achieving complete renal response with Iptacopan treatment "C" plus standard of care, compared to treatment "D" alone
Complete Renal Response is defined as meeting the following criteria: estimated glomerular filtration rate (eGFR) >90 mL/min/1.73m2 or no less than 85% of baseline value, and 24h urine protein-to-creatine ratio (UPCR) < 0.5 g/g. |
- Parte 1: Evaluar la proporción de pacientes que alcanzan la respuesta renal completa con el tratamiento `A´ de iptacopán más el tratamiento estándar en comparación con el tratamiento en monoterapia. - Parte 2: Evaluar la proporción de pacientes que alcanzan la respuesta renal completa con el tratamiento `B´ de iptacopán más el tratamiento estándar en comparación con el tratamiento `D´ en monoterapia. - Parte 2: Evaluar la proporción de pacientes que alcanzan la respuesta renal completa con el tratamiento `C´ de iptacopán más el tratamiento estándar en comparación con el tratamiento `D´ en monoterapia.
La respuesta renal completa se define como cumplir los siguientes criterios: tasa de filtración glomerular estimada (TFGe) >90 ml/min/1,73 m2 o no inferior al 85 % del valor basal y cociente proteína/creatina en orina (CPC en orina) de 24 horas <0,5 g/g. |
|
E.2.2 | Secondary objectives of the trial |
- Proportion of patients achieving complete renal response or partial renal response - Frequency of renal flares between weeks 24 and 52 - Dose exposure response for reduction in proteinurea. (each 24h urine protein-to-creatine ratio value will based on two 24 urine collections samples within 10 days before the respective study visit) - Measure fatigue in patients - Measure disease activity in SLE - Measure disease activity - Measurement of time to complete renal response based on urine samples |
- Proporción de pacientes que alcanzan la respuesta renal completa o respuesta renal parcial - Relación dosis-respuesta para la reducción de la proteinuria. (cada valor del cociente proteína/creatina en orina de 24 horas se basará en dos muestras de orina de 24 horas recogidas durante los 10 días anteriores a la visita del estudio correspondiente). - Medir la fatiga en los pacientes. - Medir la actividad de la enfermedad en el LES. - Medir la actividad de la enfermedad. - Medición del tiempo hasta la respuesta renal completa basada en muestras de orina. |

Doses should remain stable throughout the study. - First presentation or flare of lupus nephritis
