Multiple myeloma is a malignant plasma cell disorder diagnosed annually in approximately 86,000 participants worldwide. JNJ-68284528 is an autologous chimeric antigen receptor T-cell (CAR-T) therapy that targets B-cell maturation antigen (BCMA), a molecule expressed on the surface of mature B lymphocytes and malignant plasma cells. The primary hypothesis for this study is that JNJ-68284528 will significantly improve progression free survival (PFS) compared with standard therapy (PVd or DPd), in participants who have previously received 1 to 3 prior line(s) of therapy, that included a proteasome inhibitor (PI) and an immunomodulatory drug (IMiD) and who are refractory to lenalidomide. This study will be conducted in 3 phases: Screening (up to 28 days before randomization), Treatment, and Follow-Up. Assessment like patient-reported outcome(s) (PROs) assessments, electrocardiogram (ECG), vital signs, pharmacokinetic will be performed during the study. Safety evaluations will include review of ...
Chimeric antigen receptor (CAR) T cell therapy has demonstrated proven efficacy in some hematologic cancers. We evaluated the safety and efficacy of LCAR-B38M, a dual epitope-binding CAR T cell therapy directed against 2 distinct B cell maturation antigen epitopes, in patients with relapsed/refractory (R/R) multiple myeloma (MM). This ongoing phase 1, single-arm, open-label, multicenter study enrolled patients (18 to 80 years) with R/R MM. Lymphodepletion was performed using cyclophosphamide 300 mg/m2. LCAR-B38M CAR T cells (median CAR+ T cells, 0.5 × 106 cells/kg [range, 0.07 to 2.1 × 106]) were infused in 3 separate infusions. The primary objective is to evaluate the safety of LCAR-B38M CAR T cells; the secondary objective is to evaluate the antimyeloma response of the treatment based on the general guidelines of the International Myeloma Working Group. At data cutoff, 57 patients had received LCAR-B38M CAR T cells. All patients experienced ≥ 1 adverse events (AEs). Grade ≥ 3 AEs were reported

ADC molecules are engineered to deliver potent cytotoxic compounds to specific antigen-expressing target cells.1,2 Antigen binding domains recognize specific surface proteins, such as B-cell maturation antigen (BCMA), which allows for targeting of cells expressing BCMA, such as plasma and multiple myeloma cells .1,2 ADCs built with non-natural amino acid linkers could potentially ensure that the cytotoxic payload reaches the target cell.1,3 Cytotoxic molecules induce cell death when internalized by antigen-expressing target cells.3 Preclinical studies have shown that ADCs can attack tumors directly, independent of the immune system.4 Preclinical studies are ongoing to optimize, improve, and assess the potential benefits and risks of ADCs as single agent therapy or in combination with other therapies.3,5. ...
The use of monoclonal antibodies (mab) can in some cases interfere with the follow-up of MM during the assay protein electrophoresis. The thesis presents some new methods for differentiating the two immunoglobulins making correct follow-up of the disease possible. Other methods presented are new biomarkers such as B-cell maturation antigen (BCMA) and the ratio between the monocyte count and lymphocyte count, a ratio you get from the complete blood count. BCMA seems to be a promising biomarker but more research is needed before conclusions can be made about the leukocyte ratios as biomarkers because different results have been reported in articles ...

BACKGROUND. CAR T cells are a promising therapy for hematologic malignancies. B cell maturation antigen (BCMA) is a rational target in multiple myeloma (MM). METHODS. We conducted a phase I study of autologous T cells lentivirally transduced with a fully human, BCMA-specific CAR containing CD3ζ and 4-1BB signaling domains (CART-BCMA), in subjects with relapsed/refractory MM. Twenty-five subjects were treated in 3 cohorts as follows: cohort 1, 1 × 108 to 5 × 108 CART-BCMA cells alone; cohort 2, cyclophosphamide (Cy) 1.5 g/m2 plus 1 × 107 to 5 × 107 CART-BCMA cells; cohort 3, Cy 1.5 g/m2 plus 1 × 108 to 5 × 108 CART-BCMA cells. No prespecified BCMA expression level was required. RESULTS. CART-BCMA cells were manufactured and expanded in all subjects. Toxicities included cytokine release syndrome and neurotoxicity, which were grade 3-4 in 8 (32%) and 3 (12%) subjects, respectively, and reversible. One subject died at day 24 from candidemia and progressive myeloma, following treatment for ...

The samples used in this paper were obtained from patients with osteoarthritis (OA) or RA during knee-TEP operations. First of all, expression of the known BAFF-binding receptors BCMA, TACI and BAFF-R was analyzed in SF of patients with OA and RA using flow cytometry and immunohistochemistry. In a further step, the influence of several stimulants, including cytokines, TLR-agonists and cell activators on receptor expression was tested. Finally, taking into account BAFF function in other cell types, SF were stimulated with BAFF and stained with Annexin V in order to analyze its effect on apoptosis in SF ...
EGT1442 BAFF or Apr can induce activation sign in THP-1 cells which react to the excitement via production of the cytokine, IL-8, or a matrix degrading enzyme, MMP-9 (9,10). The siBAFF-transfected cells were EGT1442 tested for the responsiveness to BAFF or APRIL-mediated signaling then. As demonstrated in Fig. 2A, cells transfected with control siRNA taken care of immediately both anti-APRIL and anti-BAFF mAb and expressed large degrees of IL-8. Cells transfected with siBAFF didnt respond to the procedure with anti-BAFF mAb but taken care of immediately anti-APRIL mAb at a rate just like LPS response. The siBAFF-transfected cells had been after that treated with real estate agents that imitate its counterparts such as for example fusion protein including extracellular site of TACI (or BCMA) and Fc MYO5A part of human being immunoglobulin (TACI:Fc or BCMA:Fc). As demonstrated in Fig. 2A, both TACI:Fc and BCMA:Fc activated the cells expressing IL-8 at a rate slightly significantly less than that ...

B-cell activating factor (BAFF), also known as BlyS, TALL-1, TNAK, and zTNF4, is a TNF ligand superfamily member and has been designated TNFSF13B. It is produced by macrophages, dendritic cells, and T lymphocytes. BAFF promotes the survival of B cells and is essential for B cell maturation (1‑4). BAFF binds to three TNF receptor superfamily members: B‑cell maturation antigen (BCMA/TNFRSF17), transmembrane activator and calcium-modulator and cyclophilin ligand interactor (TACI/TNFRSF13B) and BAFF receptor (BAFF R/BR3/TNFRSF 13C). These receptors are type III transmembrane proteins that lack a signal peptide. Whereas TACI and BCMA bind BAFF and another TNF superfamily ligand, APRIL(a proliferation-inducing ligand), BAFF-R selectively binds BAFF. Mouse BAFF-R cDNA encodes a 175 amino acid residue (aa) transmembrane protein with a 71 aa extracellular domain, a 21 aa transmembrane domain, and a 83 aa cytoplasmic region. A second isoform of BAFF R that has a 72 aa cytoplamic region can also be ...
Circulating endothelial progenitor cells (EPCs) are biologic markers of endothelial function. In patients with systemic lupus erythematosus (SLE), the numerical reduction and functional impairment of EPCs contribute to the endothelial dysfunction. Through ex vivo and in vitro studies, we aimed at evaluating the effects of B lymphocyte stimulator (BLyS) on EPC colonies and endothelial cells and also investigating BLyS receptor expression on these cells. EPCs were isolated from peripheral blood mononuclear cells (PBMC). In order to evaluate their ability to form colonies, EPCs were cultured on fibronectin-coated dishes and incubated with BlyS alone or BlyS and belimumab. Apoptosis of EPCs and endothelial cell line EA.hy926 was evaluated after 6, 12, and 24 h of incubation with BLyS and after 6 h with BLyS and belimumab.

Background The TNF superfamily member B lymphocyte stimulator (BLyS), referred to as BAFF, is known to be an effective modulator of peripheral B cell homeostasis that promotes B cell survival and differentiation. BLyS is expressed by a few stromal cells, T cells, and most myeloid cell. BLyS transgenic mice show an expansion of the peripheral mature B cell compartment, hyperglobulinemia, anti-single-stranded DNA and anti-double-stranded DNA antibodies, and circulating immune complexes. A proliferation-inducing ligand (APRIL) is a homolog to BLyS that is expressed by monocytes, macrophages, DCs, T cells, and others. APRIL is virtually undetectable in normal tissues but is strongly expressed in adenocarcinomas and can accelerate the growth of malignant cells in vitro and in vivo. APRIL/BLyS heterotrimers are present in the serum of patients with systemic autoimmune diseases like rheumatoid arthritis (RA), SLE, and SS. APRIL over expression promotes a strong survival signal for both CD4+ and CD8+ T ...

The development and antigen-dependent differentiation of B lymphocytes are orchestrated by an array of growth factors, cytokines, and chemokines that require tight spatiotemporal regulation. Heparan sulfate proteoglycans specifically bind and regulate the bioavailability of soluble protein ligands, but their role in the immune system has remained largely unexplored. Modification of heparan sulfate by glucuronyl C5-epimerase (Glce) controls heparan sulfate-chain flexibility and thereby affects ligand binding. Here we show that Glce deficiency impairs B-cell maturation, resulting in decreased plasma cell numbers and immunoglobulin levels. We demonstrate that C5-epimerase modification of heparan sulfate is critical for binding of a proliferation inducing ligand (APRIL) and that Glce-deficient plasma cells fail to respond to APRIL-mediated survival signals. Our results identify heparan sulfate proteoglycans as novel players in B-cell maturation and differentiation and suggest that heparan sulfate ...
Naive peripheral B cells survive in vivo because of active stimulation by the TNF superfamily ligand B lymphocyte stimulator (BLyS/BAFF). Although the survival promoting properties of BLyS are well known, the signal pathways and molecular effectors that characterize this stimulation are still being elucidated. In this communication, we discuss the signal cascades that effect BLyS dependent survival and the regulation of BLyS induced signaling. We also examine the role of BLyS as a growth factor and propose that BLyS induced metabolic enhancement optimizes the B cell response to BCR and TLR-dependent signaling.
The monoclonal antibody 11C1 reacts with the B cell-activating factor receptor (BAFF-R), also known as BAFF receptor 3 (BR3) or CD268. It is a 19 kDa type III transmembrane protein which belongs to the TNF receptor superfamily and is mainly expressed on B cells. BAFF-R plays an important role in B cell differentiation and promotes survival and activation of B cells. - Belgique

A Proliferation Inducing Ligand (APRIL) is a TNF ligand that, via its receptors TACI and BCMA, is involved in both B cell physiology as well as in proliferation and survival of malignant B cells. To target APRIL-dependent stimulation of B cell cancers, we recently produced and characterized two monoclonal antagonistic anti-human APRIL antibodies called humanAPRIL.01A (hA.01A) and humanAPRIL.03A (hA.03A). In a first biochemical assay to validate their blocking activity, hA.01A was shown to fully prevent APRIL from binding to its receptors, whereas a substantial difference was detected for hA.03A, which inhibited APRIL binding to BCMA less efficiently than hA.01A. Epitope mapping subsequently revealed that hA.01A and hA.03A bind distinct sites on APRIL, which provided a structural rationale of their different blocking activities. Importantly, this differential inhibition profile can be used to functionally dissect BCMA and TACI-dependent signals and indicated that B cell survival and IgA ...

Tumor Necrosis Factor Ligand Superfamily Member 13: A member of tumor necrosis factor superfamily found on MACROPHAGES; DENDRITIC CELLS and T-LYMPHOCYTES. It occurs as transmembrane protein that can be cleaved to release a secreted form that specifically binds to TRANSMEMBRANE ACTIVATOR AND CAML INTERACTOR PROTEIN; and B CELL MATURATION ANTIGEN.
B cell-activating factor belonging to the TNF family (BAFF) and its receptor BAFF-R play critical roles in the maturation and survival of conventional peripheral B cells. However, they appeared to be dispensable for the generation and maintenance of CD5(+) B-1 cells as BAFF(-/-) and BAFF-R(-/-) mice have normal B-1 cell populations. Hence, it is presently unclear if B-1 cells are responsive to BAFF and if BAFF regulates some aspects of B-1 cell function. We show here that BAFF-R and transmembrane activator and CAML interactor (TACI) are the major receptors expressed by B-1 cells. Specifically, we show that BAFF treatment of B-1 cells leads to increased NF-kappaB p100 processing and CD21/CD35 expression. Interestingly, toll-like receptor (TLR) engagement of B-1 cells augmented the surface expression of BAFF receptors and rendered them responsive to BAFF costimulation, as evidenced by their increased proliferation, expression of cell surface activation markers and secretion of the pro-inflammatory

Results The mean disease duration of SLE was 7,0 [2,0-10,0] years, SLEDAI 2K score - 4 [2-13], SLICC damage index score - 0 [0-1], current prednisone dose - 10,0 [7,5-25,0] mg/day. SLE pts did not differ from healthy controls in BAFF (0,02 [0,02-0,08] vs 0,02 [0,02-0,02] ng/ml) and APRIL (0,01 [0,01-0,62] vs 0,01 [0,01-0,01] ng/ml) levels. Among SLE pts BAFF level correlated with lupus anticoagulant (r=0,88, p,0,05) and ESR (r=0,43, p,0,05); APRIL level correlated with SLEDAI 2K (r=0,55, p,0,01), CRP (r=0,50, p,0,01), antiDNA (r=0,38, p,0,05), creatinine level (r=0,39, p,0,05), current prednisone dose (r=0,55, p,0,01) and CD19 B lymphocytes absolute count (r=0,89, p,0,05). We divided SLE pts on two groups: the 1st- pts with high activity (SLEDAI 2K≥8), the 2nd - pts with low (SLEDAI 2K,8). The patients of 1st group had higher level of APRIL (1,69 [0,01-4,0] vs 0,01 [0,01-0,01] ng/ml, p,0,05) compared to 2nd group and control, there is no difference in BAFF level in these groups.. ...
BAFF and APRIL are innate immune mediators that trigger immunoglobulin G (IgG) and IgA class-switch recombination (CSR) in B cells by engaging the receptor TACI. The mechanism that underlies CSR signaling by TACI remains unknown. Here we found that the cytoplasmic domain of TACI encompasses a conserved motif that bound MyD88, an adaptor that activates transcription factor NF-kappaB signaling pathways via a Toll-interleukin 1 (IL-1) receptor (TIR) domain. TACI lacks a TIR domain, yet triggered CSR via the DNA-editing enzyme AID by activating NF-kappaB through a Toll-like receptor (TLR)-like MyD88-IRAK1-IRAK4-TRAF6-TAK1 pathway. TACI-induced CSR was impaired in mice and humans lacking MyD88 or the kinase IRAK4, which indicates that MyD88 controls a B cell-intrinsic, TIR-independent, TACI-dependent pathway for immunoglobulin diversification. ...

Introduction Blisibimod is a potent B cell-activating aspect (BAFF) antagonist that binds to both cell membrane-expressed and soluble BAFF. B cells reverted to baseline, resulting in a calculated 30 percent30 % decrease in total B cells by around 160 days following the 1st dosage. In both solitary- and multiple-dosing SC cohorts, the pharmacokinetic profile indicated sluggish absorption, dose-proportional publicity from 0.3 through 3.0 mg/kg SC and 1 through 6 mg/kg IV, linear pharmacokinetics over the dosage selection of 1.0C6.0 mg/kg, and accumulation ratios which range from 2.21 to 2.76. The comparative increase in memory space B cells had not been associated with security signals, as well as the 1192500-31-4 supplier occurrence of adverse occasions, anti-blisibimod antibodies, and medical laboratory abnormalities had been similar between blisibimod- and placebo-treated topics. Conclusions Blisibimod transformed the constituency from the B cell pool and solitary and multiple dosages of ...
