In May 2023, the first-in-human clinical trial of an experimental oral drug for removing radioactive contaminants from inside the body, testing the safety, tolerability, and processing in the body of escalating doses of the investigational drug product HOPO 14-1 was initiated in healthy adults. The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, was funding the Phase 1 trial, which was sponsored and conducted by SRI International of Menlo Park, California. In March 2022, Novartis announced that the US Food and Drug Administration (FDA) approved Pluvicto (lutetium Lu 177 vipivotide tetraxetan) for the treatment of adult patients with a certain type of advanced cancer called prostate-specific membrane antigen–positive metastatic castration-resistant prostate cancer (PSMA-positive mCRPC) that has spread to other parts of the body. These patients have already been treated with other anticancer treatments (androgen receptor pathway inhibition and taxane-based chemotherapy). To read more about the latest highlights related to the anti-radiation drugs market, get a snapshot of the key highlights entailed in the Global Anti-Radiation Drugs Market Report Anti-Radiation Drugs Overview Anti-radiation drugs are pharmaceutical compounds designed to mitigate the damaging effects of radiation exposure on the human body. These drugs work by either scavenging free radicals generated by radiation or by enhancing the repair mechanisms of cells damaged by radiation. One class of anti-radiation drugs includes radioprotectors, which are administered before radiation exposure to prevent or reduce its harmful effects. Another class, known as radiomitigators, is given after exposure to alleviate the severity of radiation-induced damage. These drugs hold significant promise in scenarios such as nuclear accidents, medical radiation therapy, and space travel, where the risk of radiation exposure is a concern. Research into anti-radiation drugs is ongoing, with scientists continually striving to improve their efficacy and minimize side effects. Some compounds under investigation show potential not only in protecting against acute radiation sickness but also in mitigating long-term effects such as cancer development. As our understanding of radiation biology advances, coupled with advancements in drug development technologies, the prospects for more effective and accessible anti-radiation drugs continue to brighten, offering hope for safer environments in radiation-prone situations. Anti-Radiation Drugs Market Insights In 2023, North America dominated the anti-radiation drugs market, primarily due to several factors contributing to growth. These include a substantial patient population afflicted with various illnesses like cancer, increasing numbers of diagnostic procedures, and governmental initiatives aimed at public health in the region. This trend is expected to continue from 2024 to 2030. The prevalence of cancer in the United States, for example, drives a significant demand for anti-radiation drugs. Statistics from the American Cancer Society projected around 2 million new cancer cases in the United States in 2024, leading to heightened demand for these drugs to support cancer diagnostic procedures. Additionally, the US benefits from a strong focus on clinical research and the presence of leading pharmaceutical companies, further bolstering the market for anti-radiation drugs. Moreover, in 2022, the US Department of Health and Human Services (HHS) allocated USD 290 million for the purchase of Nplate, a drug produced by Amgen USA Inc., intended to treat radiation sickness in the event of a nuclear emergency. This investment reflects ongoing efforts to enhance preparedness for radiological and nuclear emergencies and underscores the commitment to saving lives in such scenarios. To know more about why North America is leading the market growth in the anti-radiation drugs market, get a snapshot of the Anti-Radiation Drugs Market Outlook Anti-Radiation Drugs Market Dynamics The market dynamics of anti-radiation drugs are driven by a complex interplay of factors ranging from technological advancements to geopolitical events and regulatory frameworks.

介绍：聚山梨酯（吐温，PS）是一类两亲性非离子表面活性剂家族，其中，聚山梨酸酯80（吐温80）是生物药物制剂中使用最广泛的“明星”表面活性剂，可防止蛋白质在储存、运输条件变性、聚集、表面吸附以及絮凝作用。吐温80是一种混合物，主要成分是聚氧乙烯脱水山梨糖醇单油酸酯。作为常用的药物辅料，市售注射用吐温80主要有MC（多药典级）和CP（中国药典级）两种级别，其主要差异在油酸含量上，见表1。其中，CP级别常用供应商日油和南京威尔，MC级别有JT、Sigma和禾大等。吐温80可以通过氧化和水解途径降解，见图1，其中水解反应是化学诱导的或酶催化的，氧化反应一般由化学诱导。吐温80作为生物制剂的一种保护剂辅料使用，但也可能影响蛋白质制剂的质量，从而对功效、安全性和稳定性起到不利作用。目前，药品监管部门对吐温80的控制要求越来越严格。图1 吐温80的主要降解途径有很多学者对吐温80进行了大量研究，下面从吐温80的优缺点、含量测定方法、以及面临挑战几个方面进行介绍。吐温80的优点：PS80是生物制剂中最常用的表面活性剂，在大多数商业治疗性蛋白质制剂中用作蛋白质稳定剂。这是由于以下因素：1）生物相容性高；2）低毒性；3）有效的蛋白质稳定作用。即使在低浓度下（生物制剂中常用浓度为0.1-1.0mg/ml），它们也提供了足够的蛋白质稳定性。这是由于PS80的亲水亲脂平衡（HLB）值高和临界胶束浓度（CMC）低，PS80的CMC仅为1.4*10-2g/L。蛋白质具有天然的不稳定性，易受到外部条件的影响，如温度、震荡、剪切力、缓冲体系及离子强度等，甚至自身的蛋白浓度或纯度的改变。其中，所有蛋白质变性降解的问题中，聚集的问题尤为严重。下游的制剂开发中常常使用吐温80作为蛋白的保护剂。聚山梨酯稳定蛋白质的机理，通常认为界面竞争和表面活性剂-蛋白质复合这两种主要机理。吐温80主要通过界面竞争作用来稳定蛋白质，吐温80的表面活性比蛋白质（即单克隆抗体（mAbs））高很多，因此，吐温80可以竞争性地占据界面位置，抑制蛋白质吸附到气液交界面，进而减少与空气接触造成的氧化或聚集，也有效防止蛋白质在制造过程、样品处理和存储中在界面处展开。吐温80还可以通过与蛋白质直接相互作用，增加蛋白质的胶体稳定性。抗体可能会通过其分子间输水作用形成聚集体。吐温80可通过与蛋白质表面上的疏水相互作用，从而防止蛋白质聚集甚至颗粒的产生。吐温80的缺点：前面提到吐温80其实是一种混合物，市售的预期结构聚氧乙烯脱水山梨糖醇单油酸酯）仅占吐温80总量的20％。如图2所示，异质性主要来来源与工艺相关的副产物杂质，其中不仅含有单酯（预期结构），还含有二酯、多酯，甚至未成酯的脂肪酸链。此外，前面还提到（见图1），吐温80可以发生水解反应及氧化反应导致降解，产生脂肪酸链及氧化物，以上导致对吐温80的表征成为了难点。图2 吐温80主要的化学结构吐温80的表征：吐温80的结构缺乏强发色团，无法直接检测到容易获得的紫外可见光及荧光。目前，很多研究学者已经开发了多种表征方法来控制吐温80的不同性质，表2总结了几种常见含量检测方法的原理及优缺点。然而，由于不同亚种（如未酯化、单酯、多酯）及降解产物（如水解、氧化）对总吐温80含量结果的贡献值存在显著差异，因此用不同原理方法测定的吐温80含量显示出明显的差异。此外，还采用MS或CAD（其中主要应用色谱与MS联合应用）来分析主要吐温80亚种的组成及降解物，例如小的有机分子，游离脂肪酸等，研究解聚山梨酯降解途径。药典方法、HPLC-ELSD/CAD方法对水解产物较为敏感，HPLC-FMA也可测出样品水解，然而测定吐温80氧化方面上，FMA方法更胜一筹，综合来看，HPLC-FMA方法更适用于PS80含量的检测。截止目前为止，吐温80的表征方法层出不穷，但具有各自方法的优点及弊端，其仍然是一项分析挑战，必要时可采取多种检测方式共同评价。面临的挑战：吐温80的水解也就是酯的水解，反应生成的游离脂肪酸链可形成聚集甚至可见颗粒，并且可能与蛋白结合形成脂肪酸-蛋白复合物。在典型的蛋白质制剂pH（4-7）下，吐温80的水解受到限制。有文献表明，酶诱导的吐温80水解是影响产品质量的可见和亚可见颗粒形成的主要原因，实际生产中上游工艺带来的Hcp脂肪酶是催化PS80水解的一个重要因素，其具有与目标蛋白相似的理化性质，因此很难完全去除。即使优化纯化工艺去除Hcp，但远低于检测限的极少量Hcp（ppm级别）也可催化PS80的水解。吐温80可能被光照、温度，过氧化物、氧气或痕量金属离子等影响因素氧化，氧化位置常见脂肪酸链双键、母核的醚键和部分酯键，降解产物有自由基、过氧化物、游离脂肪酸、短链烷烃、醛、酮、酸等。而生成的过氧化物可能继而引起蛋白质氧化。泊洛沙姆188（P188）是另一种在蛋白质制剂中用作蛋白质稳定剂的赋形剂，尽管不如吐温80使用广泛。P188因不具备酯键，不会有发生水解的风险，主要通过氧化形式在溶液中降解，形成氧化的聚氧乙烯（POE）和聚环氧丙烷（PPO）。但P188在上市品种中应用局限，可能存在长期放置过程中潜在风险。因此，推荐使用一些手段减少吐温对蛋白质的负面影响，如2-8℃低温储存、充氮、避光保护；通过上游工艺优化降低Hcp；加入抗氧化剂、金属络合剂等。其中抗氧化剂如甲硫氨酸、赖氨酸、色氨酸等，金属络合剂如EDTA、DTPA等。参考文献：[1] Characterization of Polysorbate 80 by Liquid Chromatography Mass Spectrometry to Understand Its Susceptibility to Degradation and Its Oxidative Degradation Pathway Journal of Pharmaceutical Sciences 111 (2022) 323−334;[2] Characterization of Polysorbate Ester Fractions and Implications in Protein Drug Product Stability Mol.
