(NASDAQ:NTLA), a leading clinical-stage gene editing company focused on revolutionizing medicine with CRISPR-based therapies, today reported operational highlights and financial results for the second quarter ended June 30, 2024. “We are delighted to report the Phase 2 study of NTLA-2002 met its primary efficacy and all secondary endpoints at both dose levels and, importantly, provided clear support for advancing the 50 mg dose into the pivotal Phase 3 trial in patients with hereditary angioedema,” said Intellia President and Chief Executive Officer John Leonard, M.D. “Based on these positive results and our recent successful end-of-Phase 2 meeting with the FDA, we see a clear path to initiating the Phase 3 trial in the coming months. We look forward to presenting the detailed Phase 2 results at a medical meeting in the fourth quarter as we continue to advance what we believe could be a functional cure for hereditary angioedema. With three pivotal Phase 3 trials and our first gene insertion trial expected to be active by year-end, Intellia is closer than ever to transforming the future of medicine with our one-time, in vivo gene editing therapies.” Second Quarter 2024 and Recent Operational Highlights Hereditary Angioedema (HAE) NTLA-2002: NTLA-2002 is a wholly owned, investigational in vivo CRISPR-based therapy designed to knock out the KLKB1 gene in the liver, with the goal of lifelong control of HAE attacks after a single dose. Intellia announced today positive topline results from the Phase 2, randomized, double-blind, placebo-controlled study of NTLA-2002 in patients with HAE. The clinical trial met its primary efficacy and all secondary endpoints in the 16-week primary observation period, with a single 25 mg or 50 mg dose leading to deep reductions in attacks. No new safety findings were observed. Intellia has selected the 50 mg dose for further evaluation in the global pivotal Phase 3 trial based upon the greater number of patients with complete attack elimination and greater kallikrein protein reduction compared to the 25 mg dose observed in the Phase 2 study, which is consistent with the previously reported Phase 1 results. The Company plans to present the detailed Phase 2 data at an upcoming medical meeting in the fourth quarter of this year.The Company announced today the successful completion of an end-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) supporting its Phase 3 plans for NTLA-2002. The Phase 3 study is on track to initiate in the second half of 2024, subject to regulatory feedback.In June, Intellia presented positive long-term data from the ongoing Phase 1 study. Eight of 10 patients remained completely attack-free following the 16-week primary observation period. These patients have experienced ongoing attack-free durations of greater than 18 months after a single-dose treatment, with the longest ongoing individual attack-free duration reaching over 26 months. Across all patients, NTLA-2002 led to a 98% mean reduction in monthly HAE attack rate. Consistent with previously reported results, NTLA-2002 was well-tolerated, with the majority of adverse events being mild in severity through the latest follow-up. These interim data were presented at the European Academy of Allergy and Clinical Immunology (EAACI) Congress 2024 in Valencia, Spain. Transthyretin (ATTR) Amyloidosis NTLA-2001: NTLA-2001, now known as nexiguran ziclumeran (nex-z), is an investigational in vivo CRISPR-based therapy designed to inactivate the TTR gene in liver cells, thereby preventing the production of transthyretin (TTR) protein for the treatment of ATTR amyloidosis. NTLA-2001 offers the possibility of halting and reversing the disease by driving a deep, consistent and potentially lifelong reduction in TTR protein after a single dose. Intellia leads development and commercialization of NTLA-2001 in collaboration with Regeneron. ATTR Amyloidosis with Cardiomyopathy (ATTR-CM): The pivotal Phase 3 MAGNITUDE trial is enrolling rapidly and continues to track ahead of the Company’s initial projections. During the second quarter, the Company received approval for its application under the new European Union Clinical Trials Regulation, which enables the Phase 3 trial to proceed in Denmark, Germany, France, Italy, Spain and Sweden. The MAGNITUDE trial of NTLA-2001 is now cleared by regulatory agencies in over 12 countries and actively enrolling at over 35 sites globally. Hereditary ATTR Amyloidosis with Polyneuropathy (ATTRv-PN): The Company plans to initiate a pivotal Phase 3 trial of NTLA-2001 as a single-dose treatment for ATTRv-PN by year-end. As previously announced, the study is expected to be a small, placebo-controlled trial conducted at ex-U.S. sites with approximately 50 ATTRv-PN patients. Intellia plans to present updated data from the ongoing Phase 1 study in the second half of 2024. Alpha-1 Antitrypsin Deficiency (AATD)-Associated Lung Disease NTLA-3001: NTLA-3001 is a first-in-class CRISPR-mediated in vivo targeted gene insertion development candidate for the treatment of AATD-associated lung disease. It is designed to precisely insert the wild-type SERPINA1 gene, which encodes the alpha-1 antitrypsin (AAT) protein, with the potential to restore permanent expression of fully functional AAT protein to normal levels after a single dose. This is Intellia’s first wholly owned gene insertion program. In July, Intellia announced the authorization of its Clinical Trial Application by the United Kingdom’s Medicines and Healthcare products Regulatory Agency (MHRA) to initiate a first-in-human study of NTLA-3001. Intellia expects to dose the first patient in the Phase 1/2 study of NTLA-3001 in the second half of 2024. In Vivo Platform Expansion In June, Intellia presented positive clinical proof-of-concept data that redosing with CRISPR, utilizing the Company’s proprietary non-viral, LNP-based delivery platform, enabled an additive pharmacodynamic effect. In the three patients who previously received the lowest dose of 0.1 mg/kg in the Phase 1 dose-escalation study of NTLA-2001, follow-on dosing with a 55 mg dose of NTLA-2001 led to a deeper protein reduction. Median reduction in serum TTR was 90% at day 28 after redosing. The corresponding reduction from original baseline levels was a 95% median reduction in serum TTR. NTLA-2001 was generally well tolerated across all patients after receiving the follow-on dose. While redosing is not planned for the NTLA-2001 program in ATTR amyloidosis, a redosing option could be an important advantage of Intellia’s LNP-based delivery platform for future investigational therapies where a target additive effect is desired. These data were presented at the Peripheral Nerve Society (PNS) Annual Meeting in Montreal, Canada.Intellia is expanding the range of diseases that can be targeted with its CRISPR-based technologies by deploying new editing and delivery innovations. This includes advancing gene editing programs in five different tissues outside the liver, either independently or in collaboration with partners. These research and preclinical programs are targeting diseases that originate in the bone marrow, brain, muscle, lung and eye, which, if successful, could dramatically expand the opportunities for CRISPR-based treatments. Ex Vivo Program Updates Intellia is advancing multiple programs, wholly owned and in collaboration with partners, utilizing its allogeneic platform for the treatment of immuno-oncology and autoimmune diseases. The Company’s proprietary allogeneic cell engineering platform avoids both T cell- and NK cell-mediated rejection in preclinical models, a key unsolved challenge with other investigational allogeneic approaches. Cell therapies engineered with Intellia’s allogeneic platform, combined with edits to enhance cell function, offer a new approach to target both hematological and solid tumors. Corporate Updates In June, Intellia announced the appointment of Brian Goff to its board of directors. Mr. Goff joins the board of directors with over three decades of commercialization, operations and sales and marketing experience at leading biopharmaceutical companies.In June, Intellia announced the appointment of Edward Dulac as Executive Vice President, Chief Financial Officer, and Treasurer, effective July 22, 2024. Mr. Dulac succeeds Glenn Goddard, who stepped down from his role effective June 30, 2024. Mr. Dulac joins Intellia with more than 20 years of combined finance, business development and corporate strategy experience.

▎药明康德内容团队编辑 本期看点 1. 治疗阿尔茨海默病（AD）的自然杀伤（NK）细胞疗法SNK01在一项1期临床试验中使90%患者的认知功能稳定或有改善。 2. FDA批准了能在体内制造嵌合抗原受体（CAR）-T细胞的创新疗法UB-VV111的IND申请，预计将于今年年底前启动1期临床试验。 3. 有望功能性治愈乙型肝炎病毒（HBV）感染的重组多克隆抗体疗法GIGA-2339获许可进入临床。 药明康德内容团队整理 SNK01：公布1期临床试验的新数据 NKGen Biotech公布了其在研NK细胞疗法SNK01治疗阿尔茨海默病患者的临床试验数据。SNK01是一款自体、非基因工程改造的NK细胞产品，它具有增强的细胞毒性，活化受体表达率超过90%，可从任何供体中稳定生产。该候选疗法能够有效降低AD患者脑脊液（CSF）中的α-突触核蛋白（α-syn）水平，该蛋白的升高被认为与认知能力下降有关。目前，已批准的AD疗法均未将α-syn作为靶点。 此前公布的1期试验结果显示，SNK01除了先前披露的对淀粉样蛋白β（Aβ）和神经炎症生物标志物的积极影响外，对晚期AD患者的认知功能也具有临床疗效。在10名可评估的AD患者中，90%患者的阿尔茨海默病综合评分（ADCOMS，一种反映患者认知功能的评分）较基线时有改善或保持稳定。 此次公布的结果显示，尽管70%的受试者接受的是相对低剂量的SNK01治疗，仍有60%的受试者（6/10）的CSF α-syn水平较基线时有所下降。第11周时，6名患者中有5名受试者的α-syn下降与ADCOMS的稳定/下降相对应。安全性方面，没有观察到与治疗相关的不良事件。AD受试者对SNK01的耐受性良好，在所有测试剂量下均未观察到剂量限制性毒性。该公司表示，这些数据值得在更大剂量、更长疗程、更大规模的2期试验中进一步研究。 UB-VV111：IND申请获得FDA许可 Umoja Biopharma宣布，美国FDA已批准其在研CD19靶向原位生成（in-situ generated）CAR-T细胞疗法UB-VV111的IND申请，用以治疗血液恶性肿瘤。Umoja预计将在2024年底前启动1期试验并进行首位患者给药。根据新闻稿，UB-VV111可能是血液学人体试验中首个原位生成CD19靶向CAR-T细胞疗法。 UB-VV111是一款通过VivoVec平台开发的体内CAR-T细胞疗法。UB-VV111包含一个表面经过工程化的病毒包膜，以及编码CD19靶向CAR和雷帕霉素激活细胞因子受体（RACRTM）的转基因，旨在于患者体内扩增UB-VV111工程化CAR-T细胞。该疗法是VivoVec基因递送平台进入临床的首个管线。 GIGA-2339：IND申请获得FDA许可 GigaGen公司宣布，美国FDA已批准其IND申请，将于2024年第四季度启动一项1期试验，以评估该公司首款用于治疗HBV感染的重组多克隆抗体疗法GIGA-2339。GIGA-2339采用GigaGen的下一代平台开发，含有1000多种全人重组抗HBV抗体，旨在复制人体的自然免疫反应。GIGA-2339的效力是血浆衍生HBV药物的2000多倍，涵盖了广泛的循环HBV变异。在小鼠模型中，GIGA-2339中和并清除了HBV的病毒DNA及其抗原。通过这种独特的作用机制，GIGA-2339有可能清除病毒颗粒并激活免疫反应，从而提供HBV感染患者的功能性治愈。 Sabirnetug（ACU193）：公布1期临床试验的新数据 Acumen Pharmaceuticals公司公布了sabirnetug（ACU193）用于治疗AD的1期临床试验的新结果。Sabirnetug是一种选择性靶向毒性可溶性β淀粉样蛋白寡聚体（AβOs）的人源化单克隆抗体。Sabirnetug能够结合AβOs，由于其独特的结合特性，sabirnetug有可能在产生淀粉样蛋白相关成像异常（ARIA，一种抗体疗法产生的常见主要副作用）风险较低的情况下提供治疗益处，因为sabirnetug可以在不直接靶向淀粉样斑块的情况下阻断AβOs的毒性作用。 此次公布的结果显示，接受sabirnetug给药3次可显著降低患者脑脊液中突触前和突触后蛋白水平，这与sabirnetug抑制AβOs突触结合的作用机制一致。VAMP2是一种与突触损伤相关的生物标志物，在所有多剂量递增组中均显著降低，似乎是该研究中发现的对sabirnetug最敏感的生物标志物。Acumen公司计划在正在进行的为期18个月的2期临床试验中评估生物标志物的长期变化及其与临床结果的关系，以进一步证实sabirnetug的作用机制。此外，Acumen公司还宣布了sabirnetug皮下制剂治疗早期AD的1期临床试验已完成首例受试者给药。 Pepinemab：公布1b/2a期临床试验数据 Vaccinex公司公布了pepinemab治疗AD的1b/2期试验数据的良好初步结果。Pepinemab是一种人源化IgG4单克隆抗体，旨在阻断SEMA4D与plexin-B1受体结合，从而避免引发细胞内肌动蛋白细胞骨架的崩溃，以及进一步导致的大脑中星形胶质细胞和其他胶质细胞以及免疫组织中树突状细胞的稳态功能丧失。 此次公布的结果证实了以激活星形胶质细胞为目标的新型作用机制有望延缓AD从早期轻度认知障碍发展为老年痴呆症的进程。该研究结果与此前pepinemab治疗亨廷顿病的2期临床试验结果类似，因为AD与亨廷顿病在神经免疫病理学方面具有相似性。 RGX-202：公布1/2期临床试验的新数据 REGENXBIO公司宣布，其在研杜氏肌营养不良症（DMD）基因疗法RGX-202在治疗1至11岁DMD患者的1/2期临床试验中获得了积极的中期安全性和疗效数据。在接受关键性临床试验推荐剂量（剂量水平2）的RGX-202治疗的5.8岁和8.5岁患者中，接受治疗后三个月时微抗肌营养不良蛋白表达水平分别为健康对照组的77.2%和46.5%。该试验中按剂量和年龄分类的微抗肌营养不良蛋白表达结果如下表所示： ▲AFFINITY DUCHENNE试验中接受不同剂量RGX-202治疗患者的微抗肌营养不良蛋白表达水平（图片来源：参考资料[1]） RGX-202是一种一次性基于腺相关病毒载体（AAV）的基因疗法，它编码包含天然抗肌营养不良蛋白C端（CT）结构域的微抗肌营养不良蛋白，以更好地模拟天然蛋白的功能。临床前研究中，CT结构域已被证明可以保护肌肉免受收缩引起的应力，并提高其自我修复的能力。 XPro：公布1期临床试验数据 INmune Bio公司公布了其下一代肿瘤F坏死因子（TNF）抑制剂XPro用于治疗AD的1b期临床试验结果。XPro的作用与现有的TNF抑制剂不同，它能中和可溶性TNF（sTNF），而不影响跨膜TNF（tmTNF）或TNF受体。XPro可在不抑制免疫的情况下减轻神经炎症，从而对神经系统疾病患者产生潜在的实质性益处。此次公布的结果显示，接受XPro治疗12周后，患者的突触蛋白发生了显著变化，而突触蛋白对神经元之间的交流至关重要。 NTLA-3001：获批在英国启动1/2期临床试验 Intellia Therapeutics公司宣布其临床试验申请（CTA）获得英国药品与保健品管理局（MHRA）的授权，可启动一项1/2期研究以评估NTLA-3001治疗α1抗胰蛋白酶缺乏症（AATD）相关的肺部疾病的效果。AATD是一种罕见的遗传性疾病，最常见的表现是由于α1抗胰蛋白酶（AAT）蛋白水平不足导致的肺功能障碍。NTLA-3001是一种全身给药的体内一次性基因编辑疗法，它旨在通过CRISPR/Cas9技术精确插入编码AAT蛋白的SERPINA1基因的健康拷贝，单次给药就有可能使功能性AAT蛋白永久表达并恢复到治疗水平。这种方法旨在改善患者的治疗效果，包括消除每周静脉注射AAT的疗法或严重病例对肺移植的需求。 ▲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] REGENXBIO ANNOUNCES NEW POSITIVE DATA FROM AFFINITY DUCHENNE® TRIAL OF RGX-202.
