Background: PSMA-based alpha therapy using 225Ac-PSMA-I&T provides treatment for metastatic castration-resistant prostate cancer (mCRPC), even after the failure of 177Lu-PSMA radioligand therapy (RLT). In clinical routine, the total tumor volume (TTV) on PSMA PET impacts therapy outcomes and plays an increasing role in mCRPC patients. Hence, we aimed to assess TTV and its changes during 225Ac-PSMA-I&T RLT. Methods: mCRPC patients undergoing RLT with 225Ac-PSMA-I&T with available 18F-PSMA-1007 PET/CT prior to therapy initiation were included. TTV was assessed in all patients using established cut-off values. Image derived, clinical and biochemistry parameters (PSA, LDH, AP, pain score) were analyzed prior to and after two cycles of 225Ac-PSMA. Changes in TTV and further parameters were directly compared and then correlated with established response criteria, such as RECIST 1.1 or mPERCIST. Results: 13 mCRPC patients were included. The median overall survival (OS) was 10 months. Prior to 225Ac-PSMA RLT, there was no significant correlation between TTV with other clinical parameters (p > 0.05 each). Between short-term survivors (STS, <10 months OS) and long-term survivors (LTS, ≥10 months OS), TTV and PSA were comparable (p = 0.592 & p = 0.286, respectively), whereas AP was significantly lower in the LTS (p = 0.029). A total of 7/13 patients completed two cycles and underwent a follow-up 18F-PSMA-1007 PET/CT. Among these patients, there was a significant decrease in TTV (median 835 vs. 201 mL, p = 0.028) and PSA (median 687 ng/dL vs. 178 ng/dL, p = 0.018) after two cycles of 225Ac-PSMA RLT. Here, percentage changes of TTV after two cycles showed no direct correlation to all other clinical parameters (p > 0.05 each). In two patients, new PET-avid lesions were detected on 18F-PSMA-1007 PET/CT. However, TTV and PSA were decreasing or stable. Conclusion: PET-derived assessment of TTV is an easily applicable imaging biomarker independent of other established parameters prior to 225Ac-PSMA RLT in these preliminary follow-up data. Even after the failure of 177Lu-PSMA, patients with extensive TTV seem to profit from RLT. All but one patient who was eligible for ≥2 cycles of 225Ac-PSMA-RLT demonstrated drastic TTV decreases without direct correlation to other biomarkers, such as serum PSA changes. Changes in TTV might hence improve the response assessment compared to standard classifiers by reflecting the current tumor load independent of the occurrence of new lesions.

巨头重注核药赛道

中国核药产业创新链盟将举办对接交流会系列活动之“中国新药向‘核’处去”，遴选“一线一流”专家共研核药未来，助力产业创新与发展。随着诺华三季报的披露，Pluvicto在今年前三季度中取得10.41亿美元的营收，成为全球首款销售额突破10亿美元的核药产品。Pluvicto的火爆，也让核药成为各大MNC的重点布局方向。虽然核药已经拥有近百年历史，但却始终不温不火，直到RDC药物的出现，让才其重新成为肿瘤治疗领域的重要方向。与ADC原理类似，RDC也是将精准靶向分子和强力杀伤因子用连接臂偶联在一起而设计开发的一种药物形态。图：RDC结构示意图，来源：招商证券与其他小分子靶向药物或ADC药物相比，RDC药物的放射性核素不需要与细胞直接接触，Linker在起效过程中不需要断裂，提高了RDC药物在体内的稳定性和安全性。同时，由于核素通过辐射方式杀伤癌细胞，在辐射半径内，肿瘤细胞即使没有相应抗原，也能通过交叉火力效应杀伤更多肿瘤细胞，从而具有更好的抗耐药性。 RDC药物的优势以及核药在医学诊断、治疗中独特的作用让全球核药市场迅速升温。根据Precedence Research预测，2023年全球核医学市场规模为106.5亿美元，预计到2033年将超过314.4亿美元。尤其是Pluvicto销售额的持续爆发，更是验证了核药的成功路径。时代大势面前，各大MNC均在核药赛道频频加码，诺华、礼来、阿斯利康、BMS、赛诺菲频频通过投资、并购增加自身在核药领域的筹码。一场关于MNC的“核”竞赛早已悄然开启。 1 诺华：当之无愧的龙头坐拥Pluvicto这个重磅核药产品，诺华无愧是当今世界最大的核药赢家。诺华对于核药的布局，最早要追溯到2017年。诺华斥资60亿美元先后收购了法国创新药公司AAA（Advanced Accelerator Applications）和美国生物制药公司Endocyte，并以此为基础，将核素药物作为其四大技术平台之一。可以说，诺华是最早将核药技术上升到公司核心战略的MNC巨头。 2018年，诺华从AAA公司获得的首款RDC药物Lutathera得到FDA批准上市，用于治疗SSTR阳性的胃肠胰神经内分泌肿瘤患者，成为首款FDA批准的放射性配体疗法，开启了RDC靶向治疗的新时代。尽管获批的仅是市场很小的罕见病适应症，但Lutathera上市依然取得了不俗的销售成绩，上市第一年就取得了1.67亿美元的销售额，第二年营收额就增至4.41亿美元。不过，受疫情及适应症影响，Lutathera的营收在2020年-2022年陷入停滞，2023年才重新恢复增长。今年前9个月，Lutathera收获了5.34亿美元营收。图：Lutathera营收一览，来源：锦缎研究院 Lutathera仅算是诺华在核药领域的小试牛刀，2022年3月获批上市的Pluvicto才是真正的重磅产品。Pluvicto被FDA批准用于治疗去势抵抗性转移前列腺癌患者（mCRPC）。与Lutathera不同，Pluvicto针对的前列腺癌是男性第二大癌种。2023年，美国新发病人数约28.83万人，存量患者高达334万人，市场空间巨大。果然在上市后，Pluvicto不负众望的取得营收高增长。在产能受限的情况下，首年销售额就达到了2.71亿美元，2023年继续放量，全年销售额9.8亿美元，增长261%。今年前9个月，Pluvicto的营收就已经突破10亿美元大关，毫无疑问是最成功的核药产品。 Pluvicto和Lutathera的成功商业化，让诺华继续加大在核药领域的布局。通过一系列的投资及授权合作，诺华获得了大量早期研发管线，并从中选择有潜力的管线进行临床研发。目前，诺华已经有8个核药管线，包括2个上市产品和6个处于临床1期的管线。图：诺华RLT管线，来源：公司官网在核药逐渐火热的2024年，诺华也没有停止扩张的步伐。4月底，诺华与PeptiDream签署了总价值约29亿美元的合作协议，共同开发多款大环肽靶向偶联核药；5月初，又以10亿美元预付款以及7.5亿美元的潜在里程碑付款收购Mariana Oncology，以加强放射性配体疗法的布局。内部不断拓展已上市产品适应症，外部持续高效BD的战略下，诺华将核药领域变成自己的主场，希望以绝对领先的地位长期领跑该赛道。 2 拜耳：核药领域先行者拜耳在核药领域的布局虽然不及诺华，但也是较早布局核药赛道的MNC之一。早在2009年，拜耳就与Algeta联合开发Xofigo（氯化镭223），并于2013年获批上市，用于治疗晚期骨转移型去势抵抗性前列腺癌。拜耳也顺势以29亿美元的重金买下了Algeta，拿下了Xofigo的所有权益。自2013年上市后，Xofigo销售额便稳步上升，2017年达到4.71亿美元。但Xofigo仍属于传统放射性治疗药物，市场空间有限，2017年-2020年销售额分别为4.08亿欧元、3.51亿欧元、3.03亿欧元和2.62亿欧元，逐年下滑。尽管Xofigo并没有成为一款大药，但拜耳并未停止核药领域的布局，只不过与诺华全面重注核药赛道不同，拜耳更专注于开发靶向α粒子的疗法。与177Lu等发射的β粒子相比，α粒子在组织中生效的距离更短，但是在有效距离内对细胞的杀伤效果更强。 2021年的时候，拜耳大手笔收购Noria Therapeutics和PSMA Therapeutics，获得了一款靶向PSMA的小分子α粒子疗法的开发权益，这是一种基于锕-225的放射性核素疗法，此次收购扩展了拜耳的靶向α疗法（TAT）的肿瘤学产品组合。 2023年5月，拜耳又以4500万美元的预付款以及潜在高达17亿美元的里程碑付款，与Bicycle Therapeutics达成一项战略合作协议，双方将利用Bicycle的合成肽技术，在肿瘤学领域合作开发、制造和商业化RDC。目前拜耳共有7个处于临床前阶段和2个处于早期临床阶段（BAY 3546828、BAY 3563254）的RDC在研。图：拜耳核药领域布局，来源：公司官网 3 礼来：加速布局核药在减肥药和阿尔兹海默症均取得突破的礼来，亦在最近两年连续重金投入核药赛道。礼来关注核药赛道很早，早在2006年和2009年，就参与了分子成像公司Avid Radiopharmaceuticals的B轮和D轮融资，并在2010年以8亿美元收购了该公司。但此后礼来在核药领域就没有什么大的动作了。直到2023年，礼来开始加码核药赛道。先是在9月参与了Mariana Oncology 1.75亿美元的B轮融资（这家放射性药物研发公司在今年5月被诺华以10亿美元收购）；10月，礼来宣布将以14亿美元收购核药生物技术公司Point Biopharma，标志着礼来正式进军核药领域。 Point是一家放射性疗法制药公司，拥有一系列正在开发的临床和临床前阶段放射性配体疗法，用于治疗癌症。核心资产包括已处于临床III期的一款针对转移性去势抵抗性前列腺癌 (mCRPC) 的靶向PSMA的疗法PNT2002，以及下一代放射性配体疗法技术平台和相应的核药供应链。图：Point管线布局，来源：新浪医药通过这笔交易，礼来获得了核药研发、生产、制造和商业化的全产业链条，甚至可直接与诺华展开竞争。今年礼来在核药领域再度加码。先是5月与Aktis Oncology达成合作协议，以6000万美元的预付款，以及高达11亿美元的额外里程碑付款和销售特许权使用费，获得在全球范围内开发由Aktis发现的、针对礼来选定的一系列明确靶标的放射性药物和诊断产品的权利。而后又在6月与Radionetics Oncology达成战略合作，共同推进靶向GPCR的新型小分子放射性药物的研发，用于治疗广泛的实体瘤。同时，礼来向其注入1.4亿美元的前期资金，并获得了收购Radionetics的排他权，潜在收购款为10亿美元。礼来在核药领域的一系列举措，意味着其正在积极扩大其在核药领域的研发管线，未来或将在该领域有更大举动。 4 阿斯利康：24亿美元收购阿斯利康得以进入核药赛道，完全源于小规模一次投资。 2020年11月，阿斯利康与Fusion Pharmaceuticals达成合作，开发和商业化下一代α发射放射性药物和治疗癌症联合疗法。虽然这笔交易只有500万美元的首付款和4000万美元的里程碑付款，但此次交易为阿斯利康进入放射性药物领域提供了一个切入点。今年3月，阿斯利康就宣布耗资24亿美元收购了Fusion，并获得其4款在研放射性药物，包括FPI-2265、FPI-1434、FPI-2068和FPI-2059。其中FPI-2265是一款针对前列腺特异性膜抗原（PSMA）的靶向药物，用于治疗转移性去势抵抗性前列腺癌（mCRPC），II期临床试验结果表明，FPI-2265 对既往接受过大量治疗的进展性 mCRPC 患者有疗效，包括既往接受过基于177Lu放射配体疗法的患者。 5月7日，阿斯利康FPI-2265启动了一项II/III期临床研究，旨在评估 FPI-2265 在既往接受过 177Lu-PSMA-617或其它177Lu-PSMA放射性疗法治疗的PSMA阳性转移性去势抵抗性前列腺癌（mCRPC）患者中的安全性和有效性。此外，在买下Fusion三个月后，6月，阿斯利康再次投资核药CDMO公司Nucleus RadioPharma，开始布局核药产能。阿斯利康在核药领域布局虽然才刚刚开始，但一出手就是24美元的大手笔，毫不掩饰其在核药赛道的野心。 5 赛诺菲、BMS、罗氏除上述跨国药企外，布局核药的MNC队伍仍在不断扩大。今年9月，赛诺菲宣布，与RadioMedix和Orano Med达成总额超3.2亿欧元的独家许可协议，将共同开发基于同位素铅（lead）的放射性配体疗法（RLT）用于癌症治疗，首次进军核药领域。紧接着10月，赛诺菲又发布公告称，将与Orano Med共同投资一家新实体，专注于基于铅-212（²¹²Pb）α发射同位素的下一代放射性配体疗法（RLT）的发现、设计和临床开发，赛诺菲将进行3亿欧元的股权投资，占新实体约16%的股权。另一方面，BMS在2023年12月宣布以41亿美金收购成立仅三年多的核药公司RayzeBio。RayzeBio是一家处于临床阶段的放射性药物疗法（RPT）公司，在锕系元素放射性药物治疗领域处于领先地位，拥有多个潜在的“First-in-Class”和“Best-in-Class”药物开发项目。通过此次收购，BMS获得了一项胃肠胰神经内分泌肿瘤（GEP-NET）和广泛期小细胞肺癌（ES-SCLC）的临床RPT项目、多项临床前资产以及位于印第安纳州的GMP生产设施以及基于α核素的差异化放射性药物技术平台和多款在研创新产品，包括RYZ101、RYZ801等创新靶向核药。罗氏在核药的布局并不多，2023年9月，罗氏旗下的基因泰克（Genentech）与PeptiDream达成合作协议，共同发现和开发新型大环肽-放射性同位素偶联药物。为此，基因泰克付出了4000万美元预付款以及未来可能高达10亿美元的里程碑付款。这笔交易为罗氏切入核药赛道提供了很好的机会。概括而论，Pluvicto的爆发让MNC看到了核药赛道的机遇。相信随着越来越多MNC的入局，这个赛道必将在未来成为医药主流赛道之一。2024年，即是核药的爆发“元年”。同写意媒体矩阵，欢迎关注↓↓↓

在过去的几十年里，放射性药物经历了重大的转变。最初，这些药物主要用于成像，以便早期诊断癌症和其他疾病。随着治疗和诊断技术的结合，放射性药物的发展已经彻底改变了这个领域。诊疗一体化的放射性药物既能检测疾病，又能治疗疾病，为医疗提供了更具个性化的方法。正如Lantheus首席执行官Brian Markison所指出的那样，“放射性药物可以发现、战斗和跟踪。这些药物具有靶向特定癌细胞的独特能力，可提供诊断成像，并递送靶向治疗辐射来摧毁癌细胞”。放射性药物市场呈指数级增长。一份Statista市场研究报告显示，预计到2032年，放射性药物领域的价值将达到140亿美元，而目前还未达到70亿美元。“这种增长将受到诊断和治疗放射性药物的创新、接受治疗的患者数量的增加，以及这些技术在各种癌症和神经病学中应用扩大的驱动。”Markison补充道。 1 发现、对抗、跟随放射性药物正在成为一种强大的精准医学，能够“发现”、“对抗”和“跟踪”癌细胞。放射性药物包括一种靶向剂，结合放射性同位素，与癌细胞上的特定生物靶点结合。这种组合可以精确地将辐射输送到肿瘤，同时最大限度地减少对周围健康组织的伤害。这种方法使药物能够寻找到癌细胞，用靶向辐射摧毁，并跟踪治疗的有效性。在“发现”阶段，放射性药物与肿瘤特异性抗原或受体结合，如前列腺特异性膜抗原（PSMA），用于前列腺癌的治疗。附着的放射性同位素会发出γ射线，可以通过PET（正电子发射断层显像术）或SPECT（单光子发射计算机断层显像术）等成像技术探测到，这使得临床医生能够可视化肿瘤的位置和大小。 “战斗”阶段包括将β或α粒子输送到癌细胞的放射性治疗。 “大多数已确立的疗法使用发射β粒子。这些粒子（比如镥-177）在体内传播的距离相对较远，会导致单链DNA断裂，从而破坏癌细胞的生长。”Back Bay Life Science Advisors管理合伙人Peter Bak解释道。而发射α粒子（比如使用锕-225或铅-212粒子）可以造成短程辐射，这些粒子会导致双链DNA断裂。这意味着，α射线会不可逆转地破坏癌细胞，而不会损害肿瘤附近的健康组织。在“跟随”阶段，放射性药物成像可以监测治疗效果，确保剩余癌细胞被识别和处理。Clarivate医疗保健研究和数据分析师Suchitra Ghoshal说：“许多放射性药物可以使用核医学技术进行成像，从而实现对治疗的精确靶向和监测。” 这种完整的治疗和监测周期，使放射性药物成为精准肿瘤学的有效和通用方法。最近，在投资和创新方面，该领域都在加速发展。 Ghoshal分享了她认为需要改进的关键领域： • 下一代放射性示踪剂放射性示踪剂是一种先进的放射性化合物，用于PET和SPECT等成像技术，以可视化体内的生物过程。这些示踪剂通常针对与疾病（尤其是癌症）相关的特定生物标志物或代谢通路。市售放射性示踪剂的例子包括氟代脱氧葡萄糖（FDG）等。 • 诊疗学将诊断和治疗能力结合在一起的诊疗放射性药物的发展增强了核医学个性化治疗方法。Ghoshal强调，诊疗市场正在经历显著增长，特别是在各种癌症的治疗方面，包括前列腺癌、神经内分泌肿瘤和淋巴瘤。研究人员也正在研究将纳米技术整合到诊疗放射性药物中，使用各种纳米载体，如脂质体和树枝状聚合物，以改善放射性核素的递送和靶向。 • 靶向放射性药物（TRPs） TRPs用于将放射性同位素特异性地递送到表达特定生物标志物的癌细胞或组织。这些药物由靶向分子、连接剂、螯合剂和放射性核素组成，可以精确靶向肿瘤细胞，类似于抗体-药物偶联物，旨在取代传统化疗。主要目标是最大限度地提高治疗效果，同时最大限度地减少对周围健康组织的损伤。TRPs正逐渐用于神经退行性疾病的诊断。 • 放射性药物领域的AI Ghostal强调了AI对该领域做出特别贡献的一种方法——计算机分子设计。“AI通过计算机模拟方法增强了放射性药物的设计和验证。这些方法利用计算模型来预测化合物的行为，包括它们的结合性质和药代动力学（吸收、分布、代谢、排泄和毒性）。这种预测能力使开发过程更快、成本更低，减少了对传统体外和体内测试的依赖。AI的融合有望大幅扩大核医学的能力。” 2 待克服的挑战 Ghoshal指出，供应链管理是核医学面临的重大挑战。事实上，对于高效生产和分销放射性药物来说，特别是半衰期短的药物，维持可靠的供应链至关重要。这一领域还需要专门的基础设施和目前缺乏的专业工作人员。Ghoshal表示：“训练有素的核医学医生数量有限，而且我们需要多学科专业知识来有效管理放射性药物，这阻碍了放射性药物的广泛应用。” 开发和生产的高成本从长远来看，可能会限制放射性药物的可及性。除了技术挑战之外，监管也是需要解决的问题。 “由于放射性药物的独特性，包括其放射性和辐射安全要求，我们有必要建立专门的监管框架。放射性药物需要广泛的非临床和临床研究以确保其安全性和有效性。”Ghoshal补充道。这些研究除了非临床药理学、辐射暴露和影响以及影像学研究外，还包括确保人员安全参与生产和质量控制，以及在诊断过程中最大限度地减少对患者的辐射暴露，并最大限度地发挥治疗效果，同时最大限度地减少对健康组织的伤害。因此，高速发展的放射性药物行业面临的挑战也确实阻碍了该领域的投资、合作和并购。 3 “重磅”放射性药物交易目前放射性制药市场非常火爆，几笔交易对该领域产生了重大影响，其中包括Bracco Imaging和Blue Earth Diagnostics的收购案。该笔收购扩大了Bracco Imaging在精准医疗和个性化诊断方面的投资组合。Blue Earth Diagnostics带来了新型PET显像剂，如Axumin（fluciclovine F 18），可用于疑似复发性前列腺癌患者的PET显像。此外，Lantheus从Life Molecular Imaging获得了177Lu-DOTA-RM2和68Ga-DOTA-RM2的权益，使Lantheus的产品组合除了可用于治疗前列腺癌外，还增加了乳腺癌的适应症。这不仅加强了Lantheus在市场上的地位，也为患者提供了更广泛的治疗选择。去年10月，GE医疗与SOFIE生物科学公司达成的协议，有望对放射性药物领域产生重要影响。根据合作协议，GE医疗将商业化和生产SOFIE生物科学公司的两种用于癌症成像应用的试验性成纤维细胞激活蛋白抑制剂（FAPI）PET显像剂。 FAP是一种在癌症相关成纤维细胞（CAF）中高度表达的酶，CAF是肿瘤微环境的关键组成部分，支持癌细胞的生长和扩散。由于CAF存在于大多数肿瘤类型中，包括乳腺、胰腺、结肠、肺、肝和胃，因此FAP靶向诊断在肿瘤以及其他疾病（包括炎症、纤维化和关节炎）中具有巨大的潜力。这些PET放射性示踪剂目前正在美国进行II期临床试验。 4 哪些放射性药物值得留意？过去的几年里，FDA已在该领域批准了多项产品。比如，Lantheus针对癌症的靶向PET显像剂PYLARIFY于2021年获批，用于基于血清前列腺特异性抗原（PSA）水平升高的疑似前列腺癌症转移患者和疑似复发患者。 2023年，Blue Earth Diagnostics用于识别PSMA阳性病变和用于检测前列腺癌复发的高灵敏度的POSLUMA获得批准。同年，Telix Pharmaceuticals的Illucix也被批准用于选择转移性去势抵抗性前列腺癌患者，适合接受靶向PSMA放射性配体疗法Pluvicto治疗者。 Ghoshal表示，放射性药物领域的大多数临床试验都集中在PSMA和FAPI靶点上。以下是一些值得关注的试验：此外，Lantheus在肿瘤学方面还拥有几个值得关注的候选产品：PNT2002在SPLASH试验中已显示出积极的顶线结果，预计今年还会披露更多数据；治疗阿尔茨海默病的晚期β淀粉样蛋白PET显像剂NAV-4694目前处于III期开发阶段。被阿斯利康收购的Fusion Pharmaceuticals也是该领域的参与者，其用于转移性去势抵抗性前列腺癌患者的FPI-2265疗法正处于II/III期临床阶段。FPI-2059是另一项处于I期临床的候选产品。这是一种NTSR1靶向α疗法，使用actinium-225，旨在治疗多种类型的实体瘤，包括胃肠道和胰腺癌。 5 放射性制药投资前景大型制药公司正在积极收购放射性药物初创公司，增强他们在这一领域的能力。 2024年5月，诺华宣布收购Mariana Oncology。此次收购涵盖了一个强大的RLT项目组合，涉及一系列实体瘤适应症（如乳腺癌、前列腺癌和肺癌），包括针对小细胞肺癌的基于锕的先导RLT项目MC-339。不少公司也选择建立战略伙伴关系，开发新型放射性药物。一个主要的例子是Eckert & Ziegler和Alpha-9 Theranostics之间的合作，以确保actinium-225的供应，这是下一代靶向放射性核素疗法的关键组成部分。 Lantheus首席执行官认为，未来几年将会出现一波新一代放射性药物，改善靶向制剂、螯合剂、安全持有放射性同位素的分子，确保同位素安全地运输到体内的目标部位，以及调整治疗指数的同位素。毫无疑问，核医学将在未来不断发展，并为市场带来更多新的治疗方案，从癌症开始，拓展至神经退行性疾病等更多其他疾病。国内众多中国医药公司也已进军核医学领域，越来越多的资本投向这一赛道。面对相对蓝海的核药产业，如何把握机遇，用好上下游资源，避免内卷，成就高质量的创新，实现临床疗效与商业价值的双赢？ 10月24-26日，同写意将携手烟台生物医药健康产业发展集团，邀请核药领域领军人物去往烟台，在蓝色药谷生命岛深度探讨中国核药产业创新的未来。活动的第一天，中国科学院上海药物研究所分子影像中心主任、美国医学与生物工程院会士程震，东诚药业副总经理、蓝纳成生物总经理吴晓明，中信证券医药分析师袁聪敏，埃格林医药联合创始人兼CMO李长青等嘉宾，将针对核药行业现在和未来趋势进行现场分享，共寻企业合作发展大计。会议日程 2024年10月24日 09:00-12:00　注册签到 12:00-13:00　写意午宴 14:00-15:00　参观学习 15:00-15:05　开场发言 15:05-15:20　领导致辞 15:20-15:35　园区推介 15:35-16:00　科学家说中国放射性药物研究现状程　震：中国科学院上海药物研究所分子影像中心主任，美国医学与生物工程院会士 16:00-16:20　企业家说放射性药物产业发展实践及创新机遇吴晓明：东诚药业副总经理，蓝纳成生物总经理 16:20-16:40　投资者说百亿蓝海与投资方向，BD全球进展，未来趋势分析袁聪敏：中信证券医药分析师 16:40-17:00　“核”以出海？核药的全球化开发李长青：埃格林医药联合创始人兼CMO 17:00-17:10　茶歇☕ 17:10-18:00　圆桌对话中国核药向何处去 ▶　核药原始创新-放射性药物靶点多样化趋势；火爆的市场与BD交易须　涛（主持）：智核生物CEO，同写意核药俱乐部秘书长 ▶　核药全产业链开发与合作-同位素、供应链、CMC、安全评价、临床需求喻峰（主持）：亦立医药创始人、CEO 18:30-20:00　写意晚宴 2024年10月25日参观考察交流（本次活动定向邀约）参考文章： The radiopharmaceutical revolution：From diagnosis to treatment, oncology and beyond；labiotech 同写意媒体矩阵，欢迎关注↓↓↓

Convergent Therapeutics Announces First Patient Treated in Phase II Clinical Trial with Lead Therapeutic Candidate and Corporate Updates

First Patient Dosed with CONV01-α in Phase II Clinical Trial in Patients with Metastatic Castration Resistant Prostate Cancer Drug Development Veteran Richard Messmann, MD Appointed as Chief Medical Officer to Lead the Development of CONV01-α Novo Holdings Invests $40 million in Series A Extension to Advance Clinical Development of Radiopharmaceuticals at Convergent Therapeutics CAMBRIDGE, Mass., Sept. 24, 2024 /PRNewswire/ -- Convergent Therapeutics Inc., a clinical stage biotechnology company focused on developing next generation radiopharmaceutical therapies for the treatment of prostate cancer and other cancers, today announced that the first patient has been dosed with CONV01-α in the Phase II CONVERGE-01 trial evaluating CONV01-α, Ac-225 rosopatamab tetraxetan, for the treatment of patients with prostate-specific membrane antigen (PSMA) PET-positive metastatic castration resistant prostate cancer (mCRPC). Previously conducted academic studies of CONV01-α have shown encouraging therapeutic results in patients with prostate cancer. According to Neil Bander, MD, Convergent's Co-founder and CSO, "In patients treated at Weill Cornell Medicine, CONV01-α demonstrated a prostate-specific antigen decline of 50% (PSA50) in 67% of patients and a PSA decline of 90% (PSA90) in 27% of patients." These results have prompted initiation of the CONVERGE-01 trial under Convergent's own Investigational New Drug License (IND). "We look forward to evaluating the full potential of CONV01-α and advancing the Phase II trial in the months ahead." The CONVERGE-01 trial is a Phase II, randomized, open-label, multicenter three-part study designed to assess the safety and efficacy of CONV01-α in patients with mCRPC. In Part 1, the first 5 participants will receive In-111-rosopatamab tetraxetan to characterize the biodistribution of the radioantibody to target organs and prostate cancer lesions. Participants will then be enrolled in either Part 2 (dose optimization) or Part 3 (dose escalation) depending on their prior treatment history. Part 2 will enroll Lu-177-PSMA-radioligand therapy-naïve participants and Part 3 will enroll participants who received prior Lu-177-PSMA-radioligand therapy. All patients will receive Ac-225 rosopatamab tetraxetan in a single fractionated two-week cycle. Further details of the trial can be found at under NCT identifier: NCT06549465. Chief Medical Officer Appointment Convergent announced that Richard Messmann, MD, MHS, MSc, has joined the company as Chief Medical Officer. Dr. Messmann is a medical oncologist and biochemist with over 25 years of experience in oncology drug development, including responsibility for the global clinical development and successful regulatory submission of Pluvicto® and Locametz® for the treatment of men with PSMA-expressing, mCRPC. Dr. Messmann has held leadership positions at Endocyte, Advanced Accelerator Applications (a subsidiary of Novartis), Fusion Pharmaceuticals, Amgen, Eli Lilly & Co., and others. Immediately prior to joining Convergent Therapeutics, Dr. Messmann was the Senior Vice President and clinical lead for Fusion's development of the actinium radiotherapeutic FPI-2265. While at Amgen, he was the executive medical director and global program lead for the development of xaluritamig (AMG 509) in prostate cancer. "We are excited to welcome Dr. Messmann to the Convergent team as we expand our clinical program for CONV01-α," said Convergent's Co-founder and CEO, Philip Kantoff, MD. "His deep knowledge and experience in oncology drug development, specifically leading the late-stage development of radiopharmaceuticals, is an important addition to our team as we look forward to progressing this asset forward." Series A Extension Funding Convergent announced a $40 million Series A extension by Novo Holdings, a holding and investment company wholly owned by the Novo Nordisk Foundation. This additional funding increases the total Series A raise to $130 million to support the development of Convergent's radiopharmaceutical pipeline, including CONV01-α. Jim Trenkle, PhD, Partner in the Venture Investments group at Novo Holdings, joins the Convergent Board of Directors. About CONV01-α CONV01-α, Convergent's alpha emitting radioantibody, combines the precision and pharmacokinetics of antibodies with the tumor-killing potential of alpha emitting radionuclides. Specifically, CONV01-α uses a humanized monoclonal antibody targeting prostate-specific membrane antigen (PSMA) which is highly overexpressed in prostate cancer cells. Since PSMA is a validated target, several therapeutics are directed at this antigen and CONV01-α is differentiated by its use of both an antibody and alpha emitter. CONV01-α is linked to a powerful radionuclide called 225Ac, which releases alpha particles which kill cancer cells through DNA double strand breaks. Unlike other radioactive sources, alpha particles deliver high-energy radiation over very short distances, thereby minimizing radiation exposure to healthy neighboring cells and tissues. Pairing highly selective antibodies with such a powerful yet precise payload offers the ideal combination to treat many types of cancers. About Convergent Therapeutics, Inc. Convergent Therapeutics Inc. is a clinical-stage biotechnology company focused on developing tumor-selective alpha radioantibodies to target cancer. The company was founded by world-renowned experts in clinical care and research, drug development and cancer biology and its proprietary platform is licensed from Cornell University. In harnessing the selectivity of antibodies and tumor-destructive potential of alpha radioisotopes, Convergent's radioantibodies precisely target cancer cells with potent, localized radiation.
