简介

(Microbial infection) A number of viral and bacterial pathogens seem to bind MCP in order to exploit its immune regulation property and directly induce an immunosuppressive phenotype in T-cells. (Microbial infection) May act as a receptor for pathogenic bacteria Neisseria and Streptococcus pyogenes (PubMed:7708671, PubMed:9379894, PubMed:11260136, PubMed:11971006). Acts as a cofactor for complement factor I, a serine protease which protects autologous cells against complement-mediated injury by cleaving C3b and C4b deposited on host tissue. May be involved in the fusion of the spermatozoa with the oocyte during fertilization. Also acts as a costimulatory factor for T-cells which induces the differentiation of CD4+ into T-regulatory 1 cells. T-regulatory 1 cells suppress immune responses by secreting interleukin-10, and therefore are thought to prevent autoimmunity. (Microbial infection) Acts as a receptor for cultured Measles virus. (Microbial infection) Acts as a receptor for Herpesvirus 6/HHV-6. (Microbial infection) Acts as a receptor for Adenovirus subgroup B2 and Ad3.

A Phase 1 Trial of the Safety, Tolerability and Biological Effects of Intravenous Enadenotucirev, a Novel Oncolytic Virus, in Combination With Chemoradiotherapy in Locally Advanced Rectal Cancer

The use of chemoradiotherapy (CRT), in combination with surgery is the standard of care in the treatment of locally advanced rectal cancer. However some patients don't respond well to radiation.
More advanced radiotherapy techniques, that result in fewer toxicities, means that we are now able to combine new anti-cancer agents into standard treatment. Targeting the tumour early in this way has the potential to improve response rates.
Enadenotucirev is a specific type of anti-cancer virus that only targets cancer cells. It acts in the same way as any virus and can only survive by replicating inside cancer cells and not normal, non-cancerous cells. This means that it can selectively target and destroy tumours, without directly affecting normal cells. It also has the ability to attract cells from the body's immune system to help fight the cancer.
The addition of enadenotucirev to standard chemoradiotherapy treatment may have a combined effect on the cancer cells with potentially few, additional side effects.
This trial aims to determine the optimal dose and frequency of the virus to give by gradually increasing the number of doses each successive patient receives, and then increasing the dose of the virus itself. Each patient will receive a minimum of 3 doses, up to a maximum of 6, spread over the course of their 5 week standard chemoradiotherapy treatment. Patients will be closely monitored at all times to ensure that with each dosing group, there aren't excessive side effects.
Patients will then undergo surgery as part of their standard of care and be followed up for up to 4-6 weeks post-surgery.
This trial aims to determine the optimal dose and frequency that can then be used in future studies with the possibility of exploring the addition of Enadenotucirev to other chemoradiotherapy treatments.

CD46 and CD59 inhibitors enhance complement-dependent cytotoxicity of anti-CD38 monoclonal antibodies daratumumab and isatuximab in multiple myeloma and other B-cell malignancy cells.

Article

作者: Hongjie Wang ; Theo Koob ; Jonathan R Fromm ; Ajay Gopal ; Darrick Carter ; André Lieber

Multiple myeloma (MM) is an incurable malignancy of the B-cell lineage. Remarkable progress has been made in the treatment of MM with anti-CD38 monoclonal antibodies such as daratumumab and isatuximab, which can kill MM cells by inducing complement-dependent cytotoxicity (CDC). We showed that the CDC efficacy of daratumumab and isatuximab is limited by membrane complement inhibitors, including CD46 and CD59, which are upregulated in MM cells. We recently developed a small recombinant protein, Ad35K++, which is capable of transiently removing CD46 from the cell surface. We also produced a peptide inhibitor of CD59 (rILYd4). In this study, we tested Ad35K++ and rILYd4 in combination with daratumumab and isatuximab in MM cells as well as in cells from two other B-cell malignancies. We showed that Ad35K++ and rILYd4 increased CDC triggered by daratumumab and isatuximab. The combination of both inhibitors had an additive effect in vitro in primary MM cells as well as in vivo in a mouse xenograft model of MM. Daratumumab and isatuximab treatment of MM lines (without Ad35K++ or rILYd4) resulted in the upregulation of CD46/CD59 and/or survival of CD46^high/CD59^high MM cells that escaped the second round of daratumumab and isatuximab treatment. The escape in the second treatment cycle was prevented by the pretreatment of cells with Ad35K++. Overall, our data demonstrate that Ad35K++ and rILYd4 are efficient co-therapeutics of daratumumab and isatuximab, specifically in multi-cycle treatment regimens, and could be used to improve treatment of multiple myeloma.

Characterization of membrane protein interactions by peptidisc-mediated mass photometry.

Article

作者: John William Young ; Emanuel Pfitzner ; Raman van Wee ; Carla Kirschbaum ; Philipp Kukura ; Carol V Robinson

Membrane proteins perform numerous critical functions in the cell, making many of them primary drug targets. However, their preference for a lipid environment makes them challenging to study using established solution-based methods. Here, we show that peptidiscs, a recently developed membrane mimetic, provide an ideal platform to study membrane proteins and their interactions with mass photometry (MP) in detergent-free conditions. The mass resolution for membrane protein complexes is similar to that achievable with soluble proteins owing to the low carrier heterogeneity. Using the ABC transporter BtuCD, we show that MP can quantify interactions between peptidisc-reconstituted membrane protein receptors and their soluble protein binding partners. Using the BAM complex, we further show that MP reveals interactions between a membrane protein receptor and a bactericidal antibody. Our results highlight the utility of peptidiscs for membrane protein characterization in detergent-free solution and provide a rapid and powerful platform for quantifying membrane protein interactions.

In Vitro Sensitivity of Neuroendocrine Neoplasms to an Armed Oncolytic Measles Vaccine Virus.

Article

作者: Nikolai V Scheicher ; Susanne Berchtold ; Julia Beil ; Irina Smirnow ; Andrea Schenk ; Ulrich M Lauer

Neuroendocrine neoplasms represent a heterogenous group of rare tumors whose current therapeutic options show only limited efficacy. Oncolytic viruses exert their mode of action through (onco-)lysis of infected tumor cells and the induction of a systemic antitumoral immune response in a virus-induced inflammatory micromilieu. Here, we investigated the potential of our well-established second-generation suicide-gene armed oncolytic measles vaccine virus (MeV-SCD) in five human NEN cell lines. First, (i) expression of the MeV receptor CD46 and (ii) its correlation with primary infection rates were analyzed. Next, (iii) promising combination partners for MeV-SCD were tested by employing either the prodrug 5-fluorocytosine, which is converted into the chemotherapeutic compound 5-fluorouracil, or the mTOR-inhibitor everolimus. As a result, MeV-SCD was found to kill all NEN tumor cell lines efficiently in a dose-dependent manner. This oncolytic effect was further enhanced by exploiting the prodrug-converting system, which was found to be highly instrumental in overcoming the partial resistance found in a single NEN cell line. Furthermore, viral replication was unaffected by everolimus, which is a basic requirement for combined use in NEN patients. These data suggest that MeV-SCD has profound potential for patients with NEN, thus paving the way for early clinical trials.

开辟mRNA新应用的蛋白替代疗法；使截肢率降低6倍的糖尿病辅助治疗…… | 一周盘点

▎药明康德内容团队编辑本期看点1. Moderna公司公布了其开发的mRNA蛋白替代疗法mRNA-3927的首个临床试验结果，将mRNA的应用范围扩展到疫苗之外。2. 中度或重度糖尿病足溃疡感染的外用辅助治疗pravibismane在早期临床试验中能够加速缩小溃疡面积，同时使患者与糖尿病溃疡相关的下肢截肢发生率降低了约6倍。药明康德内容团队整理mRNA-3927：公布1/2期临床试验数据Moderna公司在《自然》杂志上发表了其用于治疗丙酸血症（PA）的在研mRNA疗法mRNA-3927的积极早期临床数据。PA是由丙酰辅酶A羧化酶（PCC）的α或β亚基（分别由PCCA和PCCB基因编码）的致病变异引起的，这些变异会导致PCC缺乏，并使有毒的代谢物积累。该病的特点是反复出现的危及生命的代谢失代偿事件（MDE）和多系统并发症。目前，没有针对PA的根本原因的有效治疗方法。mRNA-3927是一种通过静脉给药、由脂质纳米颗粒（LNP）包裹的双mRNA疗法，该疗法编码PCCA和PCCB亚基蛋白以恢复肝脏中功能性PCC酶活性。通过编码细胞内蛋白，mRNA疗法可能在预防和治疗急性代谢失代偿中起作用。此次公布的中期分析显示，mRNA-3927表现出良好的安全性和耐受性，接受mRNA-3927治疗的患者的发病风险降低了70%。研究人员指出，这是首个在罕见疾病患者中，使用mRNA表达细胞内蛋白，作为蛋白替代疗法的临床试验。▲mRNA-3927降低患者出现危及生命的代谢失代偿事件的次数（图片来源：参考资料[16]）Pravibismane：公布1b期临床试验数据Microbion公司公布了其外用候选疗法pravibismane作为中度或重度糖尿病足溃疡感染的辅助治疗的1b期研究结果。Pravibismane具有独特的三重新型作用模式，包括强效广谱抗感染性、抗生物膜活性和免疫调节活性。此次公布的结果显示，pravibismane的耐受性良好，全身吸收率极低，没有出现任何治疗引发的不良反应或严重不良事件。与安慰剂组相比，接受pravibismane治疗的受试者溃疡面积缩小了约3倍（85%对比30%），与糖尿病溃疡相关的下肢截肢发生率降低了约6倍（2.6%对比15.4%）。这些结果表明，局部使用pravibismane有望满足糖尿病溃疡患者的未竟药物需求，这种新疗法可以同时治疗细菌生物膜相关感染并加速缩小溃疡面积，并有可能导致伤口完全再上皮化和闭合，同时降低患者再感染和截肢的风险。Deltacel（KB-GDT-01）：公布1期临床试验中第三例患者的数据Kiromic BioPharma公司公布了其在研γ-δ T细胞（GDT）疗法Deltacel（KB-GDT-01）用于治疗IV期转移性非小细胞肺癌（NSCLC）患者的1期临床试验的积极早期疗效数据。Deltacel是一种同种异体细胞治疗产品，由未经修饰的供体来源GDT组成。Deltacel旨在利用GDT的天然效力靶向实体瘤，最初的临床开发重点是NSCLC（约占肺癌病例的80%至85%）。两项临床前研究的数据表明，Deltacel与低剂量放射治疗相结合具有良好的安全性和有效性。从治疗开始六周后获得的初步结果显示，Deltacel在控制肿瘤生长方面具有有效性，以及良好的安全性和耐受性。此前公布的首例患者在治疗前三天被确诊为病情进展活跃。接受Deltacel治疗六周后，计算机断层扫描（CT）扫描证实了此患者的病情稳定，初步的无进展生存期为一个半月。第二例患者在治疗开始前进行了核磁共振（MRI）扫描，发现了新的转移灶，这些新病灶在治疗后第六周的MRI复查中被发现已完全消退。此次公布的第三例患者在入组时疾病处于活动期，接受治疗后的第六周时，PET/CT、诊断CT和MRI扫描结果均显示患者的疾病正趋于稳定，没有出现新的转移性疾病。cNeT：公布1/2a期临床试验的中期数据Achilles Therapeutics公司公布了关于克隆性新抗原反应性T细胞（cNeT）在晚期不可切除或转移性NSCLC患者中、以及在复发性或转移性恶性黑色素瘤患者中的早期临床试验的中期数据。此次公布的数据显示，25%（3/12）的高剂量组患者达到疾病稳定（SD）状态，肿瘤体积有所缩小。而因为与IL-2相关的毒性更少，cNeT的安全性和耐受性与标准的肿瘤浸润淋巴细胞疗法相比更有优势。FG-3246：公布1期临床试验数据FibroGen公布了其与Fortis Therapeutics联合开发的潜在“first-in-class”抗体偶联药物（ADC）FG-3246（亦称FOR46）在1期临床试验中获得积极顶线数据。FG-3246旨在治疗转移性去势抵抗性前列腺癌和其他肿瘤类型，其靶向的CD46是一种细胞受体靶点，在前列腺癌和其他肿瘤类型中高度表达，并在大多数正常组织中表达非常有限。FG-3246由抗CD46抗体与抗有丝分裂剂MMAE连接而成，MMAE是一种已经过临床验证的ADC有效载荷。此次公布的结果显示，36%可评估前列腺特异性抗原（PSA）的患者被观察到PSA减少超过50%（PSA50）。对于可根据RECIST评估的患者，20%达到部分缓解（PR），定义为肿瘤缩小超过30%，中位缓解持续时间为7.5个月。在这批接受大量前期治疗的患者中，中位放射学无进展生存期（rPFS）为8.7个月。最常见的不良事件与其他包含细胞毒性药物MMAE作为载荷的ADCs一致，包括输液相关反应、疲劳、体重减轻、中性粒细胞减少和周围神经病变。Itolizumab：公布1b期临床试验数据Equillium公司公布了其在研单克隆抗体itolizumab治疗狼疮性肾炎的1b期临床试验的积极顶线数据。Itolizumab是一种潜在“first-in-class”的CD6靶向单克隆抗体，可选择性靶向CD6-ALCAM信号通路，选择性抑制致病性效应T细胞，同时保留对维持平衡免疫反应至关重要的调节T细胞。T细胞可驱动多种免疫炎症疾病，该通路在调节T细胞的活性和运输方面发挥着核心作用。此次公布的结果显示，当itolizumab联合吗替麦考酚酯/霉酚酸（MMF/MPA）和皮质类固醇使用时，与标准治疗方法相比，患者达成完全缓解（CR）和PR的比例更高，且尿蛋白肌酐比值（UPCR）的降低更为迅速和显著。大多数治疗伴发不良反应（TEAE）的严重程度被评估为轻度（1级）或中度（2级），其中两种最常见的TEAE是淋巴细胞减少和外周水肿。CONV01-α：公布1/2期临床试验数据Convergent Therapeutics的主打在研疗法CONV01-α是一种与锕-225（Ac-225）结合的单克隆抗体，靶向前列腺特异性膜抗原（PSMA）。锕-225是一种放射性α粒子发射器。CONV01-α的一个关键功能特性是，一旦与PSMA结合，它就会被内化，将其强大的放射性有效成分直接送入前列腺癌细胞，同时将对周围健康组织的损害降至最低。新闻稿指出，CONV01-α有望成为首个获批用于前列腺癌治疗的Ac-225放射性抗体。在一项针对晚期前列腺癌患者的多剂量、剂量递增研究中，患者对CONV01-α的耐受性良好，67%的患者达到了PSA50，27%的患者被观察到PSA减少超过90%（PSA90）。正在进行的研究表明，CONV01-α在单独使用或与其他癌症疗法联合使用时可能非常有效。TPST-1120：公布1期临床试验数据Tempest Therapeutics公司公布了其在研疗法TPST-1120单药或联用纳武利尤单抗治疗晚期实体瘤的1期试验的积极结果。TPST-1120是一种口服、选择性PPARα小分子拮抗剂。临床前数据显示，TPST-1120可直接杀死肿瘤细胞，并靶向肿瘤微环境中的抑制性免疫通路。这两种类型中的靶向细胞皆依赖脂肪酸代谢，该代谢过程由PPARα转录因子调节。在一项针对接受过多次治疗的晚期实体瘤患者的1期临床试验中，TPST-1120单药治疗和与PD-1抑制剂纳武利尤单抗联合应用均导致肿瘤缩小及生物标志物的变化。此次公布的临床数据显示，TPST-1120单药或联用纳武利尤单抗的耐受性良好，最大耐受剂量尚未确定。在接受单药治疗的患者中，53%（10/19）可评估患者的最佳缓解是SD，其中5名患者的治疗时间超过5个月。21%的患者（4例）在接受治疗后靶病灶缩小，另有3例患者的最佳缓解是靶病灶无生长。在此前接受过多线治疗的胆管癌（CCA）、肝细胞癌（HCC）和肾细胞癌（RCC）患者的联合治疗队列中，所有剂量水平的客观缓解率（ORR）为23%（3/13，均为PR）。在曾接受过抗PD-1治疗并疾病进展的RCC和CCA患者中，ORR为50%（2/4）。全血标本分析显示，PPARα相关免疫基因的表达与TPST-1120的剂量水平有关。其中一些变化仅在部分获得缓解的患者中观察到，这说明TPST-1120的生物活性与患者的临床结局有关。SZN-043：公布1a期临床试验数据Surrozen公司公布了SZN-043在健康受试者和肝硬化患者中进行的1a期临床试验的最新进展。SZN-043是采用Surrozen的SWEETS技术开发的首个候选药物，旨在治疗严重肝病。在这项研究中，SZN-043在所有受试者中均表现出了可接受的安全性和耐受性。在有肝病史的肝硬化患者中，SZN-043能够呈剂量依赖性地激活Wnt信号转导，并改善患者的肝功能。ELI-002：公布1期临床试验的新数据Elicio Therapeutics公司公布了其在研治疗性癌症免疫疗法ELI-002治疗具高复发风险胰腺癌和结直肠癌患者的新临床试验数据，这些患者携带KRAS G12D和G12R突变。ELI-002由AMP修饰的KRAS突变体（mKRAS）肽段，和一种AMP修饰的免疫刺激寡核苷酸佐剂ELI-004组成，经皮下给药靶向淋巴结。它能产生RAS特异性杀伤性T细胞，以攻击术后残留肿瘤细胞，有望延长癌症患者缓解并可预防未来复发。此次公布的结果显示，68%接受ELI-002治疗的患者产生了细胞毒性mKRAS特异性CD4+T细胞；84%的患者产生了细胞毒性mKRAS特异性CD8+T细胞；大多数接受ELI-002治疗的患者都出现了抗原扩散，诱导的T细胞靶向mKRAS以外的其他患者特异性肿瘤突变；在大多数接受ELI-002加强剂量治疗的患者中观察到持久的mKRAS特异性T细胞应答，记忆T细胞表型增加。大家都在看药明康德为全球生物医药行业提供一体化、端到端的新药研发和生产服务，服务范围涵盖化学药研发和生产、生物学研究、临床前测试和临床试验研发、细胞及基因疗法研发、测试和生产等领域。如您有相关业务需求，欢迎点击下方图片填写具体信息。▲如您有任何业务需求，请长按扫描上方二维码，或点击文末“阅读原文/Read more”，即可访问业务对接平台，填写业务需求信息▲欲了解更多前沿技术在生物医药产业中的应用，请长按扫描上方二维码，即可访问“药明直播间”，观看相关话题的直播讨论与精彩回放参考资料（可上下滑动查看）[1] Hanmi Pharm submits IND to US FDA for obesity drug HM15275 phase 1 trial.

▎药明康德内容团队编辑FibroGen日前宣布，与Fortis Therapeutics联合开发的潜在“first-in-class”抗体偶联药物（ADC）FG-3246（亦称FOR46）在1期临床试验中获得积极顶线数据。FG-3246是一款靶向CD46的ADC。这项试验纳入至少对一种雄激素受体信号抑制剂（ARSI）耐药的转移性去势抵抗性前列腺癌（mCRPC）患者。完成的1期试验共包括56名患者。这些患者接受过大量的前期治疗，在接受FG-3246治疗之前已接受过中位数为5线的治疗。在有效性分析中，36%可评估前列腺特异性抗原（PSA）的患者观察到PSA减少超过50%。对于可根据RECIST评估的患者，20%达到部分缓解，定义为肿瘤缩小超过30%，中位缓解持续时间为7.5个月。在这批接受大量前期治疗的患者中，中位放射学无进展生存期（rPFS）为8.7个月。最常见的不良事件与其他包含细胞毒性药物MMAE作为载荷的ADCs一致，包括输液相关反应、疲劳、体重减轻、中性粒细胞减少和周围神经病变。FG-3246是一种潜在“first-in-class”的全人源化抗体偶联药物，由Fortis Therapeutics与FibroGen联合开发，用于治疗转移性去势抵抗性前列腺癌和其他肿瘤类型。FG-3246靶向的CD46是一种细胞受体靶点，在前列腺癌和其他肿瘤类型中高度表达，并在大多数正常组织中表达非常有限。FG-3246由抗CD46抗体与抗有丝分裂剂MMAE连接而成，MMAE是一种已经过临床验证的ADC有效载荷。FG-3246在临床前和临床研究中展示了抗肿瘤活性。FG-3246目前正在加州大学旧金山分校进行的1/2期研究中接受评估，与恩杂鲁胺联合使用，初步数据预计在2024年中期公布。FibroGen预计在2024年下半年启动治疗转移性去势抵抗性前列腺癌的2期临床试验。大家都在看▲欲了解更多前沿技术在生物医药产业中的应用，请长按扫描上方二维码，即可访问“药明直播间”，观看相关话题的直播讨论与精彩回放参考资料：[1] FibroGen Announces Topline Results from Phase 1 Monotherapy Study of FG-3246 in Patients with Metastatic Castration-Resistant Prostate Cancer.
