Type I anti-CD20 antibodies such as rituximab fail to achieve complete B-cell depletion in lupus nephritis (LN). NOBILITY tested whether enhanced B-cell depletion with the type II anti-CD20, obinutuzumab (OBI), could improve responses in LN compared to placebo (PBO). (NCT02550652)


Patients with active Class III/IV LN (n=125) received standard-of-care mycophenolate and steroids and were randomized to OBI or PBO and followed for 104 weeks. The primary endpoint (EP) was complete renal response (CRR) at week 52. Key secondary EPs included overall renal response (ORR) and modified CRR (mCRR). Results through week 76 are reported. The two-sided alpha level was 0.2.


Baseline mean urine protein:creatinine ratio (UPCR) and serum creatinine were 3.1 g/g and 0.84 mg/dL. OBI was associated with increased renal responses vs. PBO at weeks 52 and 76 (Table). 80% of OBI pts and 0% of PBO pts had CD19+ count <0.441 cells/μL at week 52. Significant improvements in anti-dsDNA, C3, and C4 were observed with OBI vs. PBO. Through week 76, serious adverse events (OBI 24% vs. PBO 29%) and serious infections (6% vs. 18%) were not increased with OBI. Nonserious infusion-related reactions were more common with OBI (16% vs. 10%). There were 5 deaths (1 OBI, 4 PBO).


NOBILITY met its primary and secondary efficacy EPs. OBI was superior to PBO for the achievement of renal response at 12 and 18 months in proliferative LN patients treated with mycophenolate and steroids. There were no unexpected safety findings.
