Abstract:

Inevitable relapses remain as the major therapeutic challenge in patients with mantle cell lymphoma (MCL) despite FDA approval of multiple targeted therapies and immunotherapies. Fc gamma receptors (FcγRs) play important roles in regulating antibody-mediated immunity. FcγRIIB, the unique immune-checkpoint inhibitory member of the FcγR family, has been implicated in immune cell desensitization and tumor cell resistance to the anti-CD20 antibody rituximab and other antibody-mediated immunotherapies; however, little is known about its expression and its immune-modulatory function in patients with aggressive MCL, especially those with multi-resistance. In this study, we found that FcγRIIB was ubiquitously expressed in both MCL cell lines and primary patient samples. FcγRIIB expression is significantly higher in CAR T-relapsed patient samples (p < 0.0001) compared to ibrutinib/rituximab-naïve, sensitive or resistant samples. Rituximab-induced CD20 internalization in JeKo-1 cells was completely blocked by concurrent treatment with BI-1206, a recombinant human monoclonal antibody targeting FcγRIIB. Combinational therapies with rituximab-ibrutinib, rituximab-venetoclax and rituximab-CHOP also induced CD20 internalization which was again effectively blocked by BI-1206. BI-1206 significantly enhanced the in vivo anti-MCL efficacy of rituximab-ibrutinib (p = 0.05) and rituximab-venetoclax (p = 0.02), but not the rituximab-CHOP combination in JeKo-1 cell line-derived xenograft models. In patient-derived xenograft (PDX) models, BI-1206, as a single agent, showed high potency (p < 0.0001, compared to vehicle control) in one aggressive PDX model that is resistant to both ibrutinib and venetoclax but sensitive to the combination of rituximab and lenalidomide (the preclinical mimetic of R2 therapy). BI-1206 sensitized the efficacy of rituximab monotherapy in a PDX model with triple resistance to rituximab, ibrutinib and CAR T-therapies (p = 0.030). Moreover, BI-1206 significantly enhanced the efficacy of the rituximab-venetoclax combination (p < 0.05), which led to long-term tumor remission in 25% of mice. Altogether, these data support that targeting this new immune-checkpoint blockade enhances the therapeutic activity of rituximab-based regimens in aggressive MCL models with multi-resistance.

Preparation, identification, and functional analysis of monoclonal antibodies against atypical porcine pestivirus NS3 protein

作者: Yang, Wenting ; Huang, Jingling ; Chen, Jianing ; Yan, Miaomiao ; Liu, Guangliang

Atypical porcine pestivirus (APPV) had been detected in many countries. However, to date, a commercial detection kit is not available because of a lack of specific monoclonal antibodies (mAbs) to APPV. We generated 7 mAbs targeting the NS3 protein of APPV. Isotyping results indicated that all of these mAbs are IgG1 with a kappa light chain. We analyzed the epitopes recognized by mAbs 2B6, 6G11, 8D1, 8D3, and 8F12, which recognized the same linear epitope (GRIKSAYSDE); the 6H3 and 7E10 mAbs recognized 2 different conformational epitopes. Applications of these antibodies were verified by ELISA, western blot, indirect immunofluorescence assay, and flow cytometry. The antibodies were functionally workable for these immunoassays except for 8F12, which could not be used in flow cytometry.

Insights into the biological features of the antigenic determinants recognized by four monoclonal antibodies in redia and adult stages of the liver fluke Fasciola hepatica

Fasciola hepatica is a digenean trematode which infects a wide variety of domestic animals and also humans. Previous studies have demonstrated that four monoclonal antibodies (Mabs) against the total extract of F. hepatica redia (named as 1E4, 6G11, 4E5 and 4G11) also recognized the excretion - secretion antigens (ES Ag) of adult parasites, which is a biologically-relevant mixture of molecules with functional roles during infection and immune evasion on definitive hosts. In the present report we describe the partial characterization of the epitopes recognized by these Mabs by heat treatment, mercaptoethanol reduction, pronase proteolysis and sodium peryodate oxidation, which suggested their predominant protein and conformational nature. Also, a comparative study using immunodetection assays on crude extracts and on histological sections of both rediae and adults of F. hepatica were performed to explore the expression pattern of the antigenic determinants in these developmental stages. From these experiments it was found that the Mabs reacted most likely with the same proteins of approximately 64 and 105 kDa present on both rediae and adult's extracts. However, the 1E4, 6G11 and 4E5 Mabs also recognized other molecules of the total extract of F. hepatica adults, a fact that constitutes an evidence of the antigenic variation between both stages and points at a certain biological relevance of the recognized antigenic determinants. Immunolocalization studies on histological sections revealed that all Mabs reacted with the tegument of F. hepatica in both rediae and adults stages, while the epitopes recognized by 1E4, 6G11 and 4E5 antibodies were also preferentially localized in the intestinal caeca and in different organs of the reproductive system of adult specimens. The immunogenicity of these antigenic determinants, their conserved status among different stages of the life cycle of F. hepatica and their presence in both tegument and ES Ag of adult parasites, are suitable features that suggest their potential use for developing an epitope-based vaccine for fasciolosis control.

BioInvent announces the enrollment of the first patient in triple combination arm of BI-1206, rituximab and Calquence® for the treatment of non-Hodgkin's lymphoma

First patient enrolled in Phase 2a study arm combining BI-1206 with rituximab and acalabrutinibwith initial data expected YE 2024 Clinical supply agreement for acalabrutinib with AstraZeneca in place Lund, Sweden – September 12, 2024 – BioInvent International AB (“BioInvent”) (Nasdaq Stockholm: BINV), a biotech company focused on the discovery and development of novel and first-in-class immune-modulatory antibodies for cancer immunotherapy, today announces it has enrolled the first patient in the triple combination arm of the Phase 1/2a study of its anti-FcgRIIB antibody, BI-1206 in non-Hodgkin's lymphoma (NHL). The Phase 2a study arm will combine the subcutaneous formulation of BI-1206 and rituximab with Calquence® (acalabrutinib), a selective inhibitor of Bruton's tyrosine kinase (BTK). Approximately 30 patients are expected to be enrolled in Spain, Germany, the US, and Brazil. Preliminary data are expected by the end of 2024. In February 2024 BioInvent signed a clinical supply agreement with AstraZeneca (LSE/STO/Nasdaq: AZN) to provide Calquence® for the combination arm. "The enrolment of the first patient in the study is an important milestone as we move forward to evaluate this triple combination as a potential new treatment option for patients with non-Hodgkin's lymphoma," said Martin Welschof, Chief Executive Officer of BioInvent. "The combination of BI-1206 and rituximab has already demonstrated promising signs of clinical efficacy with a favorable safety profile, and we have strong reasons to believe that the addition of acalabrutinib will increase response rates even further; the subcutaneous formulation of BI-1206 is expected to provide a great deal of flexibility and further improve the tolerability of the treatment." About BI-1206BI-1206 is one of BioInvent’s most advanced drug candidates and is developed to re-establish the clinical effect of existing cancer treatments such as pembrolizumab and rituximab, drugs with combined global sales of approximately USD 28.5 billion annually. The drug candidate is evaluated in two separate clinical programs, one for the treatment of non-Hodgkin’s lymphoma (NHL, a type of blood cancer) and one for the treatment of solid tumors. Two delivery formulations (intravenous (IV) and subcutaneous (SC)) of BI-1206 are being evaluated in parallel. BI-1206 in NHLAll patients in the ongoing Phase 1/2a study (NCT03571568) have previously been treated with one or more rituximab containing treatments. Latest results were presented in connection with EHA (European Hematology Association) congress in June 2024: the intravenous (IV) Phase 1 part (dose escalation) showcased responses across the dose range of 30-100 mg, including 5 patients with complete response (CR), 1 with partial response (PR) and 6 patients with stable disease (SD) out of 17 evaluable patients. First data from the subcutaneous (SC) Phase 1 part (dose escalation) showed 1 CR, 2 PR and 1 SD out of 4 evaluable patients. About BioInventBioInvent International AB (Nasdaq Stockholm: BINV) is a clinical-stage biotech company that discovers and develops novel and first-in-class immuno-modulatory antibodies for cancer therapy, with currently five drug candidates in six ongoing clinical programs in Phase 1/2 trials for the treatment of hematological cancer and solid tumors.
