About this trial
The main objective is to assess the safety and tolerability of inebilizumab in adult participants with active and refractory systemic lupus erythematosus (SLE) with nephritis (Subprotocol A) and to assess the safety and tolerability of subcutaneous (SC) blinatumomab in adult participants with active and refractory SLE with and without nephritis (Subprotocol B Part A) and in adult participants with active refractory rheumatoid arthritis (RA) (Subprotocol C Part A). The trial will also assess the efficacy of SC blinatumomab in adult participants with active and refractory SLE with and without nephritis (Subprotocol B Part B and Subprotocol C Part B).
Eligibility criteria
Qualifiers
Subprotocol A and B: Diagnosis of SLE according to 2019 European League Against Rheumatism and the American College of Rheumatology (ACR) classification criteria.
Antinuclear antibodies (ANA) ≥ 1:80
Anti-double stranded deoxyribonucleic acid (anti-dsDNA) antibodies elevated to above normal range (ie, positive results)
AntiSmith antibodies elevated to above normal (ie, positive results).
Disqualifiers
Subprotocol A, B and C: Receipt of a live and/or live attenuated vaccine within 4 weeks prior to first dose of trial drug, during the treatment period, or until B-cell repletion after the end of the treatment period. Administration of inactivated (killed) vaccines is acceptable.
Subprotocol A and B: Estimated glomerular filtration rate (eGFR) of < 30 mL per minute per 1.73 m² of body surface area (calculated using the Modification of Diet in Renal Disease [MDRD] formula, with screening laboratory results for serum creatinine value).
Subprotocol A and B: Significant likely irreversible organ damage related to SLE (eg, end-stage renal disease [ESRD]).
Subprotocol A and B: Any acute, severe lupus related flare during screening that needs immediate treatment.
