Troculeucel

▎药明康德内容团队编辑 3个月缓解阿尔茨海默病症状，NK细胞疗法早期临床结果积极 NKGen Biotech今日公布了其自体增强型自然杀伤（NK）细胞疗法troculeucel用于治疗中度阿尔茨海默病（AD）的1/2a期临床试验中1期患者队列的中期数据，并宣布完成了2期试验的首位患者给药。 1期患者队列已显示出积极的中期结果，三位患者在接受60亿细胞治疗的三个月后，均未发生与药物相关的不良反应。此外，探索性疗效分析显示，三位患者中的两位在临床痴呆评分总分（CDR-SB）量表上从中度AD改善至轻度AD。这些发现进一步支持了该公司1期研究MX04的结果，在该研究中，一位接受最大剂量（40亿细胞）治疗的中度AD患者同样从中度改善至轻度AD。 基于troculeucel在中度阿尔茨海默病患者中1期试验的积极结果，NKGen公司宣布已启动2期临床试验并完成首位患者给药。2期试验为一项随机、双盲、安慰剂对照试验，旨在评估troculeucel与安慰剂相比在中度阿尔茨海默病患者中的疗效。2期试验将全面了解troculeucel在治疗阿尔茨海默病方面的潜在益处和局限性，从而验证其治疗潜力。NKGen目前已在北美启动了四个临床试验点，并预计在未来几个月内增加患者入组。 Troculeucel（曾名为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。 GSK流感mRNA疫苗2期结果积极 GSK今日宣布其mRNA季节性流感疫苗项目的2期临床试验取得积极结果。该试验研究了针对老年和年轻成人的多种mRNA配方，评估了与现有标准治疗相比，候选疫苗是否能提高对流感A和B病毒株的免疫反应。 在年轻人和老年人群中，试验达到了预先定义的成功标准。中期数据表明，所有测试的mRNA配方都具有可接受的安全性和反应原性。 这些结果与之前的2期临床试验结果结合，证实了mRNA平台能够诱导强大的抗体滴度，且具有可接受的安全性。基于这些结果，GSK的mRNA季节性流感疫苗项目将进入后期临床开发阶段。 此外，GSK最近与CureVac签署了一项新的许可协议，获得开发和生产流感及COVID-19候选疫苗的完全权益。GSK还通过投资和合作不断发展和优化其mRNA能力，包括在基于人工智能/机器学习的序列优化、纳米颗粒设计和制造方面的投入。 ▲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] GSK announces positive headline data from phase II seasonal influenza mRNA vaccine programme.

Two of the first three patients in the Phase 1 cohort of the Phase 1/2a clinical trial, treated at the highest dose of 6 billion cells per treatment, were found to have improved CDR-SB cognitive scores, resulting in a clinical upgrade from moderate AD to mild AD after only three months on therapy. First patient dosed in the Phase 2 cohort of the trial, continuing at the highest dose of 6 billion cells per treatment. With the advancement to Phase 2 of the trial, SNK01 will now be referred to by its INN name, “troculeucel”. SANTA ANA, Calif., Sept. 12, 2024 (GLOBE NEWSWIRE) -- NKGen Biotech, Inc. (Nasdaq: NKGN) (“NKGen” or the “Company”), a clinical-stage biotechnology company focused on the development and commercialization of innovative autologous and allogeneic natural killer (“NK”) cell therapeutics, today announced promising early interim data from the Phase 1 cohort and the dosing of the first Phase 2 patient in the Phase 1/2a clinical trial of troculeucel, NKGen’s cryopreserved autologous enhanced NK cell therapy for the treatment of moderate Alzheimer’s disease (“AD”). The Phase 1 cohort is already demonstrating positive interim results. Early independent review of the data shows that after only three months treatment with a dose of 6 billion cells per treatment, the three patients in the Phase 1 cohort had no drug-related adverse reactions, and exploratory efficacy analyses showed that two of the three patients went from a moderate to a mild AD rating on the Clinical Dementia Rating-Sum of Boxes (“CDR-SB”) scale. These findings further support the company’s MX04 Phase 1 AD study, where the one moderate AD patient who received the highest dose in that study (4 billion cells) also went from a moderate to a mild rating on the CDR-SB. Additionally, six-month interim cognitive data from Phase 1 cohort patients receiving troculeucel is expected to be disclosed at an upcoming national Alzheimer’s conference in Q4 2024. Building upon positive interim Phase 1 results of troculeucel in moderate Alzheimer’s patients, the Company is pleased to have dosed its first patient in the Phase 2 randomized, double-blind, placebo-controlled trial evaluating the efficacy of troculeucel compared to placebo in patients with moderate Alzheimer’s disease. Troculeucel will be evaluated for effectiveness and additional safety in a broader cohort of 30 patients with moderate Alzheimer’s disease, employing a randomized, double-blind setup (n=20 randomly assigned to the treatment arm and n=10 to placebo). The Phase 2 trial aims to provide a thorough understanding of both the potential benefits and limitations of troculeucel in treating Alzheimer’s disease, thereby validating its potential therapeutic efficacy. NKGen has now activated four clinical sites across North America and expects to increase enrollment in the coming months. “We continue to make great progress with our troculeucel clinical program in AD,” said Paul Y. Song, MD, Chairman and CEO of NKGen. “In the Phase 1 cohort of the Phase 1/2a study, we can proudly announce two of our first three patients have been clinically upgraded from moderate to mild AD following only three months of treatment with troculeucel. Additionally, we have recently dosed the first patient in the Phase 2 cohort, which is a significant milestone, particularly since the dose used is cryopreserved and continuing at our highest dosing of 6 billion cells per treatment. With encouraging cognitive improvements and a favorable safety profile from the trial’s Phase 1 interim analysis, dosing our first patient in Phase 2 is a crucial step towards creating a much-needed treatment option for patients facing this challenging condition. We are particularly eager to explore the enhanced cognitive benefits that ongoing usage of the higher dosing may bring in our Phase 2 trial.” About Troculeucel (formerly SNK01) Troculeucel is a novel cell-based, patient specific ex vivo expanded autologous natural killer (“NK”) cell, immunotherapeutic drug candidate.
