Conditions

Systemic Lupus Erythematosus., Lupus Nephritis

Brief summary

Safety parameters include vital signs, adverse events, laboratory parameters and ECG evaluation.

Detailed description

YTB323 transgene concentration by qPCR over time in peripheral blood; cellular kinetics parameters (Cmax, AUC, Tmax, T1/2, Clast, Tlast)., Pre-existing and treatment induced immunogenicity (cellular, humoral) of YTB323., Manufacture success (defined as meeting release specification and at or above the planned target dose)., At various timepoints: - SLEDAI-2K - Physician's global assessment - LLDAS - Remission (DORIS), UPCR at various timepoints., Complete Renal Response (CRR) at various timepoints.
