Profiling the impact of anti-human CD20 monoclonal antibodies on lymphocyte B cell subsets and their precursors in the bone marrow and in lymphoid tissues in an immunocompromised mouse engrafted with human cells

Ofatumumab (OFA) and ocrelizumab (OCRE) are two anti-CD20 monoclonal antibodies approved for the treatment of relapsing forms of multiple sclerosis due to their ability to deplete B lymphocytes. The aim of this study was to investigate the impact of these anti-hCD20 antibodies on B lymphocyte subsets in the circulation and in primary and secondary lymphoid organs in an immune system humanized mouse model (immunocompromised Rag2^-/-Il2rg^-/-CD47^-/-) engrafted with human CD34+ hematopoietic stem cells. Three months after humanization, mice, which present adaptive immune cells only of human origin, were treated with OFA (0.3 mg/Kg; day 1, 3 and 5), or OCRE (10 mg/kg; day 1) or saline. Seven days after the last injection a robust (>90 %) decrease of circulating human CD20+ B lymphocytes was observed in both OFA- and OCRE-treated mice. A partial replenishment of B lymphocytes was detectable in blood 36 days from the last injection in OFA-treated mice, while no B lymphocytes could be detected in OCRE-treated mice up to 65 days post injection. Bone marrow profiling showed that during hCD20+ B cell depletion and replenishment, OCRE-treated mice preserved only preB-I cells in the bone marrow, while the bone marrow of OFA-treated mice presented both preB-I as well as preB-II cells, with the latter subset being the one closest to differentiate into immature B cells. These data together with changes in B cell distribution in other tissues suggest that ofatumumab preserve BM niches, critical for B lymphocyte replenishment, limiting potential side effects of the treatment associated with the increased risk of infection.

slan+ Monocytes Kill Cancer Cells Coated in Therapeutic Antibody by Trogoptosis

AbstractMonocytes positive for 6-Sulfo LacNAc (slan) are a major subset of nonclassical CD14dimCD16+ monocytes in humans. We have shown that slan+ cells infiltrate lymphomas and elicit an antibody-dependent cellular cytotoxicity (ADCC) of neoplastic B cells mediated by the anti-CD20 therapeutic rituximab. Herein, by performing blocking experiments and flow cytometry analyses, as well as confocal microscopy and live-cell imaging assays, we extended the findings to other humanized antibodies and deciphered the underlying effector mechanism(s). Specifically, we show that, after coculture with target cells coated with anti-CD20 or anti-CD38, slan+ monocytes mediate trogocytosis, a cell–cell contact dependent, antibody-mediated process that triggers an active, mechanic disruption of target cell membranes. Trogocytosis by slan+ monocytes leads to a necrotic type of target cell death known as trogoptosis, which, once initiated, was partially sustained by endogenous TNFα. We also found that slan+ monocytes, unlike natural killer (NK) cells, mediate a direct ADCC with all types of anti-CD47 analyzed, and this was independent of their IgG isotype. The latter findings unveil a potentially relevant contribution by slan+ monocytes in mediating the therapeutic efficacy of anti-CD47 in clinical practice, which could be particularly important when NK cells are exhausted or deficient in number. Overall, our observations shed new light on the cytotoxic mechanisms exerted by slan+ monocytes in antibody-dependent tumor cell targeting and advance our knowledge on how to expand our therapeutic arsenal for cancer therapy.

IMM0306, a fusion protein of CD20 mAb with the CD47 binding domain of SIRPα, exerts excellent cancer killing efficacy by activating both macrophages and NK cells via blockade of CD47-SIRPα interaction and FcɣR engagement by simultaneously binding to CD47 and CD20 of B cells

CD47, as the 'don't eat me' signal, interacts with the inhibitory signal-regulatory protein alpha (SIRPα) receptor expressed by myeloid cells and activated NK cells and is overexpressed in different malignancies, causing tumors to escape the phagocytosis of macrophages.Here, we describe the antitumor mechanism of IMM0306, a fusion protein of CD20 monoclonal antibody (mAb) with the CD47 binding domain of SIRPα , by activating both macrophages and NK cells via blockade of CD47-SIRPα interaction and FcγR engagement by simultaneously binding to CD47 and CD20 of B cells in different mouse xenograft tumor models.IMM0306 is a fusion protein of CD20 mAb with the CD47 binding domain of SIRPα on both heavy chains, that was constructed and produced using an inhouse developed CHO-K1 cell expression system; whose binding activity was analyzed by flow cytometry.The phagocytosis and in vitro anti-tumor activity of IMM0306 were evaluated by antibody-dependent cellular phagocytosis (ADCP), antibody-dependent cell-mediated cytotoxicity (ADCC), and complement-dependent cytotoxicity (CDC) assays.The ADCC assay showed that IMM0306 has strong ADCC induced by activating NK cells through enhanced Fc/ FcγRRIIIa interaction.In conclusion, our data demonstrated that IMM0306, a fusion protein of CD20 mAb with the CD47 binding domain of SIRPα , exerts excellent cancer killing efficacy by activating both macrophages and NK cells via blockade of CD47-SIRPα interaction and FcγR engagement by simultaneously binding to CD47 and CD20 of B cells.We conclude the mechanism of action of IMM0306 by blocking the CD47 'don't eat me' signal and activating the Fc-receptor 'eat me' signal of CD20 with a strong ADCP to make the B-cell fully killed, whereas CD47 mAbs and rituximab can only either block the CD47 'don't eat me' signal or activate the Fc-receptor 'eat me' signal of CD20 with limited ADCP to make the limited B-cell killed.The Fc segment of the recombinant protein in IMM0306 is IgG1 and has been modified by ADCC-enhanced genetic engineering.Therefore, it has strong in vivo efficacy (through ADCC and ADCP).For other CD47 BsAbs, because the CD47 antibody itself combines with red blood cells, IgG1 cannot be selected; otherwise, it will have severe anemia toxicity.Therefore, this data revealed that IMM0306 has a safer profile and superior therapeutic potential than other CD47 mAbs and BsAbs.

自免热潮下：逆势翻盘的biotech们

▎Armstrong 近两年来MNC纷纷扫货自免产品，包括单抗、双抗、TCE、CAR-T等，这股热潮也蔓延至资本市场，一些历经波折的biotech有了逆风翻盘的机会。 Alpine Alpine Immune成立于2015年，早期核心管线为CD28/ICOS拮抗剂，但临床开发并不顺利，肿瘤管线同样推进不顺利。最近几年，Alpine的核心管线才转为TACI-Fc融合蛋白Povetacicept，今年即将推进到三期临床。 Alpine Immune的市值长期徘徊在10亿美元左右，伴随着自免风口的到来，今年4月，Vertex以49亿美元收购Alpine。 TCE：Cullinan、同润生物、恩沐生物 TCE领域的B细胞靶向CD3双抗，原本主要用于血液瘤，在资本市场上关注度并不高。随着CD19 CAR-T在自免领域的开拓性探索，行业开始高度关注TCE在自免领域的潜力。Cullinan Oncology的核心管线CD3/CD19双抗，率先在今年4月宣布转战自免赛道，并很快完成2.8亿美元增发募资。同时，Cullinan Oncology将名字也直接改成了Cullinan Therapeutics。同润生物的首发管线同样为CD3/CD19双抗CN201，同润生物在2018年完成1.5亿美元A轮融资，此后未再融过资。今年8月，默沙东以7亿美元引进同润生物的CN201。根据CN201今年ASCO会议上汇报了血液瘤的一期临床数据，其中5mg以上剂量对于FL/MCL/MZL/SLL的ORR达到100%。安全性方面，CRS发生率为7%，且均为1级或2级，同时没有神经毒性。恩沐生物成立于2016年，首发管线CMG1A46为一款CD3/CD19/CD20三抗，如今推进到血液瘤一期临床阶段。恩沐生物的融资并不算顺利，2021年A+轮融资后，与博锐生物做过一次授权合作，此后近三年无新的融资。前不久，恩沐生物完成主流美元基金Foresite Capital的新一轮融资，并一起推动了昨日与葛兰素史克的授权合作，后者以3亿美元预付款+5.5亿美元的价格引进了CMG1A46的全球权益。总结虽然自免风口带来了新的机会，但也要看到真正实现逆风翻盘的，还是那些分子设计上具有显著差异化优势，并且经过初步临床验证的biotech。Alpine的Povetacicept亲和力远高于Vera的Atacicept和荣昌生物的泰它西普，并经过二期临床验证。同润生物的CN201安全性优势显著，且B细胞淋巴瘤疗效显著。恩沐生物的CMG1A46同时覆盖CD19、CD20两个经过验证的B细胞靶点，且为活性更强的2+1价态设计。 Armstrong技术全梳理系列 GPRC5D靶点全梳理； CD40靶点全梳理； CD47靶点全梳理；补体靶向药物技术全梳理；补体药物：眼科治疗的重要方向； Claudin 6靶点全梳理； Claudin 18.2靶点全梳理；靶点冷暖，行业自知；中国大分子新药研发格局；被炮轰的“me too”；佐剂百年史；胰岛素百年传奇； CUSBEA：风雨四十载；中国新药研发的焦虑；中国生物医药企业的研发竞争；中国双抗竞争格局；中国ADC竞争格局；中国双抗技术全梳理；中国ADC技术全梳理； Ambrx技术全梳理； Vir Biotech技术全梳理； Immune-Onc技术全梳理；亘喜生物技术全梳理；康哲药业技术全梳理；科济药业技术全梳理；恺佧生物技术全梳理；同宜医药技术全梳理；百奥赛图技术全梳理；腾盛博药技术全梳理；创胜集团技术全梳理；永泰生物技术全梳理；中国抗体技术全梳理；德琪医药技术全梳理；德琪医药技术全梳理2.0；和铂医药技术全梳理；荣昌生物技术全梳理；再鼎医药技术全梳理；药明生物技术全梳理；恒瑞医药技术全梳理；豪森药业技术全梳理；正大天晴技术全梳理；吉凯基因技术全梳理；基石药业技术全梳理；百济神州技术全梳理；百济神州技术全梳理第2版；信达生物技术全梳理；信达生物技术全梳理第2版；中山康方技术全梳理；复宏汉霖技术全梳理；先声药业技术全梳理；君实生物技术全梳理；嘉和生物技术全梳理；志道生物技术全梳理；道尔生物技术全梳理；尚健生物技术全梳理；康宁杰瑞技术全梳理；科望医药技术全梳理；科望医药技术全梳理2.0；岸迈生物技术全梳理；礼进生物技术全梳理；康桥资本技术全梳理；余国良的抗体药布局；荃信生物技术全梳理；安源医药技术全梳理；三生国健技术全梳理；仁会生物技术全梳理；乐普生物技术全梳理；同润生物技术全梳理；宜明昂科技术全梳理；派格生物技术全梳理；迈威生物技术全梳理； Momenta技术全梳理； NGM技术全梳理；普米斯生物技术全梳理；普米斯生物技术全梳理2.0；三叶草生物技术全梳理；贝达药业抗体药全梳理；泽璟制药抗体药全梳理；恒瑞医药抗体药全梳理；齐鲁制药抗体药全梳理；石药集团抗体药全梳理；豪森药业抗体药全梳理；华海药业抗体药全梳理；科伦药业抗体药全梳理；百奥泰技术全梳理；凡恩世技术全梳理。
