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

Q4 · AGRICULTURAL & FORESTRY SCIENCE

Author: 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

Q4 · MEDICINE

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 to Present Additional Promising Phase 1/2a Data at EHA 2024 for BI-1206 with rituximab in NHL

First data for the SC arm: 1 complete response (CR), 2 partial response (PR), 1 stable disease (SD) out of 4 evaluable patients. Further updates from the IV arm; a fifth CR has been observed, adding to a total of 5 CR, 1 PR and 6 SD out of 17 evaluable patients. Data to be presented at the European Hematology Association, June 13-16, 2024. BI-1206 is developed to re-establish the clinical effect of existing cancer treatments such as rituximab and is evaluated as both intravenous (IV) and subcutaneous (SC) administration. Phase 2a trial plans to include a triple combination with BI-1206, rituximab and acalabrutinib. LUND, SE / ACCESSWIRE / May 14, 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 announced that promising clinical data for BI-1206 in relapsed/refractory (R/R) non-Hodgkin lymphoma (NHL), dosed in combination with rituximab, will be presented in a poster at the European Hematology Association congress held in Madrid, Spain from June 13-16, 2024. "We are pleased to share further validating Phase 1/2a data for BI-1206 in NHL during EHA. There is a high unmet need to develop treatments that can overcome resistance and improve the durability of responses to rituximab, an essential part of NHL treatment. We believe BI-1206 has the potential to meet this need," said Martin Welschof, Chief Executive Officer of BioInvent. "To identify the best options and meet the needs of clinicians and patients, we are evaluating BI-1206 administration as both IV and SC. IV dosing so far has produced response rates of a 35% ORR (overall response rate), 29% CRR (cumulative response rate) and 71% DCR (disease control rate), and we see promising early efficacy data from the subcutaneous dosing. In addition, we report an ORR of 56% in the subset of patients with follicular lymphoma (FL). Based on these encouraging results, we plan to initiate a Phase 2a study arm where the BTK inhibitor, acalabrutinib (Calquence®), will be added to the rituximab and BI-1206 combination, which should further increase response rates." BI-1206 is also being developed for the treatment of solid tumors and data will be presented at ASCO 2024. Abstract summary: Title: Safety And Preliminary Efficacy Of BI-1206, An Antibody To CD32B (FcγRIIB), Given In Combination With Rituximab In Subjects With Indolent B-Cell Non-Hodgkin Lymphoma Abstract#: P1135 Session: Indolent and mantle-cell non-Hodgkin lymphoma Date: June 14, 2024 Time: 6 - 7 pm CEST Overview: While anti-CD20 antibodies such as rituximab are a cornerstone of NHL care, approximately 15% of patients are refractory to treatment and 25% relapse within 3 years after treatment. The inhibitory Fc receptor CD32b (FcγRIIB) promotes resistance by triggering tumor cells to internalize and destroy rituximab. BI-1206 has been designed as an anti-FcγRIIB mAb to block rituximab internalization. Methods: BioInvent conducted a Phase 1/2a trial in several R/R B-cell NHL subtypes to evaluate safety and tolerability of BI-1206 in combination with rituximab. Dose expansion is ongoing for the IV formulation since the recommended Phase 2 dose (RP2D) of IV BI-1206 has been established. Phase 1 dose escalation is still ongoing for the SC formulation. Safety and Efficacy Results (May 2024): Safety: Thrombocytopenia and elevated transaminase levels were the most frequent treatment-emergent adverse events (TEAEs). The events resolved with a median duration of 4 days without any clinical complication. DLTs were not observed with intravenous (IV) dosing after pre-treatment with corticosteroids. Efficacy: In the FL subset of 16 evaluable patients (IV+SC), an ORR of 56% and CRR of 38% were observed. SC administration: In the SC dosing arm, in 4 evaluable patients, 1 complete response (CR), 2 partial response (PR) and 1 stable disease (SD) were observed. The full poster will be posted to the company's website shortly after the presentation in June. About BI-1206 The anti-FcyRIIB antibody BI-1206 is being evaluated in two separate tracks: for the treatment of NHL and solid tumors. It blocks a receptor class found on tumor cells as well as on certain immune cells, including macrophages. By selectively blocking this receptor, the aim is to improve the efficacy and/or overcome resistance from targeted therapies for hematologic cancers (including rituximab) and solid tumors (including agents that target PD-1/PD-L1). FcγRIIB is overexpressed in several forms of NHL and overexpression has been associated with poor prognosis in difficult-to-treat forms of NHL, such as mantle cell lymphoma. By blocking the receptor FcγRIIB on tumor cells, BI-1206 is expected to recover and enhance the activity of rituximab, or other anti-CD20 monoclonal antibodies, in the treatment of several forms of NHL. The combination of the two drugs could provide a new and important option for patients suffering from NHL and represents a substantial commercial opportunity. An SC formulation is being developed in parallel to the IV and patient recruitment to the Phase 1 part with BI-1206 SC as well as to the Phase 2a expansion cohorts with BI-1206 IV is ongoing.
