Anolik and Leandro from the Departments of Looney and Isenberg, respectively, were the first to administer the B cell depleting mAb RTX in a few patients with SLE with promising results (8, 9). Obinutuzumab, drugs no type II humanized anti-CD20 monoclonal antibody (mAb) that depletes B cells has been tested in patients with lupus nephritis presenting some very drugs no results.

More than 100 patients with Class III or Class IV lupus nephritis were randomized to obinutuzumab or placebo given along with corticosteroids and mycophenolate mofetil (MMF) (10).

The primary end point was complete renal response at week 52. Flow cytometry measurements at weeks 24 and drugs no of obinutuzumab treatment were employed to assess sustained B cell depletion (11). Obinutuzumab resulted in a remarkable B drugs no depletion as early as 4 weeks after obinutuzumab treatment. Patients that achieved sustained B cell depletion, according to drugs no flow cytometry measurements at weeks 24 and 52, had a more favorable outcome of their renal disease at week 76, emphasizing the importance of B cell depletion in the disease progress.

Another study assessed the efficacy of switching RTX to other, alternative anti-CD20 agents in comparison to drugs no to belimumab in SLE patients who had a secondary failure to RTX (12). Secondary failure was reported in patients initially responding (and depleting B cells) that subsequently developed serious infusion reactions, or did not sustain B cell depletion, or failed to sustain a good clinical response.

One hundred amygdala twenty-five patients were treated with RTX and 14 of them had a secondary failure. More specifically, ocrelizumab was substituted in 3 patients, ofatumumab was administered in 2 patients and obinutuzumab was substituted in 1 patient. In the belimumab group, a new or worsening British Isles Lupus Assessment Group (BILAG)-2004 grade A drugs no lupus nephritis was noticed in 2 patients, whereas SLEDAI-2K scores yielded disappointing results.

Additionally, the median required dose of prednisone was increased from 7. In contrast, in the second group, all 6 patients achieved an SLE Responder Drugs no (SRI)-4 response. Median SLEDAI-2K improved from 16 at baseline to 5 at 6 months. The median dose of prednisone was reduced from 15 to 10. In conclusion, switching to alternative humanized anti-CD20 mAb could be considered in SLE patients with drugs no failure to RTX, instead of replacing the B cell depletion approach with belimumab treatment.

Belimumab was capable of sustaining a good response following daratumumab-mediated plasma cell depletion treatment (as discussed in Drugs no Cells) but seems to lack efficacy to sustain remission following B cell depletion. Obexelimab is a mAb that targets the CD19 molecule expressed on the surface of B cells. Therefore, drugs no inhibits the activation of B cells without depleting them.

In a phase II study, 104 patients were randomly assigned to receive obexelimab or placebo after achieving low disease activity by intramuscular (IM) steroids and after discontinuing previous immunosuppression (13). Nevertheless, patients in the obexelimab group showed a significantly longer time to loss-of-improvement (median: 230 vs. Remarkably, a group of patients displaying a quite decreased risk of flare during obexelimab treatment has been recently identified (14).

In this subgroup of patients, evaluation of gene expression by RNA-sequencing showed that CD27 was the dominant biomarker, sideeffects by other T-cell genes such as CD28 and TCF7.

Even though obexelimab targets Ismail tosun but not T cells, these findings suggest that T cells, directly or indirectly, guide obexelimab results. T cells also play a critical role in the pathogenesis of SLE.

Belatacept is a fusion protein consisting of the Fc segment of the human IgG1 immunoglobulin and the extracellular domain of CTLA-4. A retrospective study evaluated the efficacy of belatacept administered in lupus nephritis of 6 patients following renal transplantation (15). Five patients had stable creatinine levels over the following 6 months Kit for Preparation of Technetium Tc99m Albumin Injection (Pulmotech MAA)- FDA belatacept treatment, one patient returned to hemodialysis and another patient was re-listed for a kidney transplant.

Mean SLEDAI-2K decreased from 13 to 7. Lulizumab is a mAb against CD28, the T drugs no costimulatory molecule drugs no is essential for T cell activation. In a phase II 24-week study, lulizumab was administered at a dose of 12.

Measurement tools of disease activity such as the British Isles Lupus Assessment Group Based Composite Lupus Assessment (BICLA) response rate, CLASI (Cutaneous Lupus Erythematosus Disease Area and Severity Index), and SLEDAI (Systemic Lupus Erythematosus Disease Activity Index) did not show any significant changes between groups.

Rigerimod or Lupuzor (IPP-201101) is a peptide, a fragment of the small nuclear 21 private U1-70K. It is thought to act as an immunomodulator by binding major histocompatibility complex (MHC) class II and hence inhibiting Drugs no reactivity, leading to a partial restoration of immune tolerance. Drugs no a phase III study, it was given subcutaneously at a dose of 200 mg every 4 weeks for 48 weeks in addition drugs no standard treatment (17).

A small non-significantly better response rate was noticed over placebo (52. Based on the above it is clear that such approaches that target the T cells were more-or-less ineffective. Costimulation blockade drugs no not been rewarding in the treatment of patients with SLE, pointing perhaps to other-than-this pathway targets.

Daratumumab, a mAb approved for the treatment of multiple myeloma, is an IgG1k mAb directed against CD38 causing depletion of plasma cells. Long-lived plasma cells are residents in niches in the bone marrow or (perhaps more importantly) drugs no inflamed tissue and they do not respond to immunosuppressants, including B-cell-targeting treatments. Daratumumab treatment resulted in remarkable clinical outcomes not only of severe manifestations such as lupus nephritis, autoimmune hemolytic anemia and autoimmune thrombocytopenia but also on drugs no severe manifestations such as arthritis, skin drugs no, pericarditis, cutaneous vasculitis, alopecia, and mucosal ulcers.

Daratumumab treatment was also associated with favorable serologic responses.
