Phase II Study of PEGPH20 and Pembrolizumab (MK-3475) for Patients With Previously Treated Hyaluronan High (HA-High) Metastatic Pancreatic Ductal Adenocarcinoma

This study is the study of the combination of PEGPH20 and Pembrolizumab (MK-3475) for patients with previously treated Hyaluronan High (HA-high) metastatic pancreatic ductal adenocarcinoma. This study is an interventional, unblinded, open label study. Approximately 35 subjects will be enrolled. The trial will require approximately a total of 18 months, including 12 months for enrollment, with an additional 6 months for patient follow-up, data collection and study closure.
Each subject will participate in the trial from the time the subject signs the Informed Consent Form (ICF) through the final contact. After a screening phase of up to 21 days, eligible subjects will receive PEGPH20 beginning with Cycle 1 Day 1, on Days 1, 8 15 of every 3 week-cycles and pembrolizumab beginning on Cycle 1 Day 1 (2-4 hrs after PEGPH20), every 3-week-cycles.
Treatment with PEGPH20 and pembrolizumab will continue until progressive disease (PD), unacceptable adverse events (AEs), intercurrent illness that prevents further administration of treatment, investigator's decision to withdraw the subject, subject withdraws consent, pregnancy of the subject, noncompliance with trial treatment or procedure requirements, subject receives 35 treatments (approximately 24 months) of pembrolizumab, or administrative reasons requiring cessation of treatment. Subjects who discontinue for reasons other than PD will have post-treatment follow-up for disease status until PD, initiating a non-study cancer treatment, withdrawing consent, or becoming lost to follow-up. All subjects will be followed by telephone for overall survival (OS) until death, withdrawal of consent, or the end of the study.
After the end of treatment, each subject will be followed for 30 days for AE monitoring. Serious adverse events (SAE) and events of clinical interest (ECI) will be collected for 90 days after the end of treatment or for 30 days after the end of treatment if the subject initiates new anticancer therapy, whichever is earlier.

Pathophysiology-Driven Approaches for Overcoming Nanomedicine Resistance in Pancreatic Cancer

Review

作者: Unni, Ashok R. ; Nair, Sreejith Thrivikraman ; Mangalanandan, T S ; Pavithran, K. ; Sarma, Manjit ; Kamalasanan, Kaladhar ; Sithara, MS ; Abhi, C

Tumor heterogeneity poses a significant challenge in cancer therapy. To address this, we analyze pharmacotherapeutic challenges by categorizing them into static and dynamic barriers, reframing these challenges to improve drug delivery, efficacy, and the development of controlled-release nanomedicines (CRNMs). This pathophysiology-driven approach facilitates the design of novel therapeutics tailored to overcome obstacles in pancreatic ductal adenocarcinoma (PDAC) using nanotechnology. Advanced biomaterials in nanodrug delivery systems offer innovative solutions by combining controlled release, stimuli sensitivity, and smart design strategies. CRNMs are engineered to modulate spatiotemporal signaling and control drug release in PDAC, where resistance to conventional therapies is particularly high. This review explores pharmacokinetic considerations for nanomedicine design, RNA interference (RNAi) for stromal modulation, and the development of targeted nanomedicine strategies. Additionally, we highlight the limitations of current animal models in capturing the complexities of PDAC and discuss notable clinical failures, such as PEGylated hyaluronidase (Phase III HALO 109-301 trial) and evofosfamide (TH-302) with gemcitabine (MAESTRO trial), underscoring the need for improved models and treatment strategies. By targeting pathways like Notch and Hedgehog and incorporating stimuli-sensitive and pathway-modulating agents, CRNMs offer a promising avenue to enhance drug penetration and efficacy, reshaping the paradigm of pancreatic cancer treatment.

Hyaluronidase improves the efficacy of nab-paclitaxel after prolonged angiogenesis inhibition in preclinical models for esophagogastric cancer

Article

BACKGROUNDLong-term anti-angiogenesis leads to pruned vasculature, densely deposited extracellular matrix (ECM), and consequently reduced chemotherapy delivery in esophagogastric cancer (EGC). To address this issue, we evaluated the efficacy of adding a hyaluronidase or a NO-donor to the regimen of chemotherapy and anti-angiogenic drugs.METHODSA patient-derived EGC xenograft model was developed. Grafted mice were randomly assigned to four experimental groups and one control group. The experimental groups received DC101, a murine angiogenesis inhibitor, and nab-paclitaxel (NPTX), with the addition of hyaluronidase (PEGPH20), or NO-donor (nitroglycerine, NTG), or their combination, respectively. We compared tumor growth during 17 days of treatment. We performed immunohistochemistry for ECM components hyaluronan (HA) and collagen, CD31 for endothelial cells, and γH2AX for DNA damage. The positively stained areas were quantified, and vessel diameters were measured using QuPath software.RESULTSProlonged DC101 treatment induced deposition of HA (p<0.01) and collagen (p<0.01). HA was effectively degraded by PEGPH20 (p<0.001), but not by NTG as expected. Both PEGPH20 (p<0.05) and NTG (p<0.01) dilated vessels collapsed in response to long-term DC101 treatment. However, only PEGPH20 (rather than NTG) was found to significantly inhibit tumor growth (p<0.05) in combination with NPTX and DC101.CONCLUSIONSThese findings suggest that the mechanical barrier of HA is the major reason responsible for the resistance developed during prolonged anti-angiogenesis in EGC. Incorporating PEGPH20 into the existing treatment regimen is promising to improve outcomes for patients with EGC.

Limiting extracellular matrix expansion in diet-induced obese mice reduces cardiac insulin resistance and prevents myocardial remodelling

Article

OBJECTIVEObesity increases deposition of extracellular matrix (ECM) components of cardiac tissue. Since obesity aggregates with insulin resistance and heart disease, it is imperative to determine whether the increased ECM deposition contributes to this disease cluster. The hypotheses tested in this study were that in cardiac tissue of obese mice i) increased deposition of ECM components (collagens and hyaluronan) contributes to cardiac insulin resistance and that a reduction in these components improves cardiac insulin action and ii) reducing excess collagens and hyaluronan mitigates obesity-associated cardiac dysfunction.METHODSGenetic and pharmacological approaches that manipulated collagen and hyaluronan contents were employed in obese C57BL/6 mice fed a high fat (HF) diet. Cardiac insulin sensitivity was measured by hyperinsulinemic-euglycemic clamp and cardiac function was measured by pressure-volume loop analysis in vivo.RESULTSWe demonstrated a tight association between increased ECM deposition with cardiac insulin resistance. Increased collagen deposition by genetic deletion of matrix metalloproteinase 9 (MMP9) exacerbated cardiac insulin resistance and pirfenidone, a clinically available anti-fibrotic medication which inhibits collagen expression, improved cardiac insulin resistance in obese mice. Furthermore, decreased hyaluronan deposition by treatment with PEGylated human recombinant hyaluronidase PH20 (PEGPH20) improved cardiac insulin resistance in obese mice. These relationships corresponded to functional changes in the heart. Both PEGPH20 and pirfenidone treatment in obese mice ameliorated HF diet-induced abnormal myocardial remodelling.CONCLUSIONOur results provide important new insights into the role of ECM deposition in the pathogenesis of cardiac insulin resistance and associated dysfunction in obesity of distinct mouse models. These findings support the novel therapeutic potential of targeting early cardiac ECM abnormalities in the prevention and treatment of obesity-related cardiovascular complications.

默沙东开辟“新战场”

MNC为了对冲重磅产品的销售峰值可以有多拼？别人拼不拼不知道，但当今药王的拥有者默沙东是拼了。K药的核心专利将于2028年到期，为了延缓K药的专利悬崖，默沙东先是All in了“IO+ADC”组合布局，花费大价钱引进第一三共、科伦博泰ADC管线，近期又为了抵御PD-(L)1/VEGF双抗的迭代，耗费不菲的资金拿下礼新医药PD-1/VEGF双抗权益。如今，默沙东又为K药开辟了“新战场”。近日，默沙东宣布皮下注射剂MK-3475A治疗转移性非小细胞肺癌（NSCLC）关键性三期MK-3475A-D77的结果，与静脉注射剂K药相比，MK-3475A治疗组达到药代动力学终点上的非劣性，并在未来公布更全面的数据与监管机构共享，预计该试验将支持所有实体瘤的适应症。 “卷剂型”并不是只有K药一家的策略，在K药之前，罗氏的T药（阿替利珠单抗）皮下注射剂型便获得FDA批准。除此之外，BMS、恒瑞医药、百济神州、君实生物等PD-(L)1玩家均有对此布局。而这也不是PD-(L)1独有的现象，近日第一三共与韩国生物技术公司Alteogen合作，开发Enhertu的皮下注射版本。那么，皮下注射剂型到底有何魅力之处？ <01> 皮下注射的知识点皮下注射的优点显而易见，主要围绕患者依从性和延长产品专利期两个方面： 1）对比传统静脉注射剂型，皮下注射制剂作为一种即用型制剂，在注射时间、患者依从性等层面存在显著优势。比如静脉输注剂型一般需要的30-90分钟，而PD-(L)1皮下注射制剂2-7分钟内即可完成给药，极大缩短了过往静脉注射的给药时间； 2）开发皮下注射剂型能够有效延长药物专利，以罗氏CD20利妥昔单抗为例，该药物在2018产品专利到期，2017年其开发了利妥昔单抗和透明质酸酶的组合物（利妥昔Hycela），新剂型只需要5-7分钟完成皮下注射，而利妥昔Hycela专利保护期至少延长至2030年；从静脉注射到皮下注射，具体的难点是如何实施的呢？皮下注射制剂开发的关键难点是给药体积限制所带来的挑战，由于要考虑注射速度、注射部位、个体患者特征（疼痛感觉敏感性）等多方面因素，通常皮下给药最大注射量约为1-2 mL（以1.5ml以内最佳），要想和静脉注射制剂达到相同的给药剂量就往往需要制备高浓度的蛋白制剂，而高浓度蛋白溶液则往往会带来稳定性差、高粘度、蛋白溶解度、蛋白降解和聚集等问题。目前主流的皮下制剂所用到的一种物质——透明质酸酶，治疗性抗体与透明质酸酶的复方制剂能够在几分钟内给予大体积、高剂量的生物制剂来解决难以开发成高浓度制剂的难题。透明质酸酶，不仅可以显著增加皮下给药的最大注射量，同时可以采用局部注射的方式对透明质酸进行水解，从而降低细胞间质粘性，实现顺利给药。透明质酸存在于人体皮下间隙，作为液体流动的一个屏障，透明质酸酶可通过在注射部位局部暂时清除该屏障，药物可进入皮下间隙并分散，24小时之内透明质酸即可在皮肤下恢复。目前，已经有多款含透明质酸酶的生物制剂获得上市批准，其中不乏有因皮下注射剂型的上市而加速产品放量的品种。图片来源：Biologics CMC <02> 皮下注射“卖水人”Halozyme 起源于圣地亚哥的Halozyme公司，其旗下的ENHANZE技术平台被投资者、媒体称之为“专利提款机”。早在1940年开始，动物源PH20透明质酸酶已被用于增加其他注射药物或液体的吸收和分散。Halozyme公司的ENHANZE技术平台核心是一种专有的重组人透明质酸酶（rHuPH20），rHuPH20是通过基因重组技术人工合成的人源性透明质酸酶，解决了过往动物源性透明质酸酶制剂导致人过敏反应的问题。在rHuPH20成为“专利提款机”之前，Halozyme公司也曾遭遇过大的挫折，其将聚乙二醇化的rHuPH20（PEGPH20）的适应症布局扩展到了胰腺癌，其设计逻辑是将PEGPH20作用于肿瘤微环境，用于破坏致密肿瘤组织中的透明质酸，使化疗药物更容易进入。2019年，Halozyme宣布PEGPH20在一项针对胰腺癌的3期HALO-301试验中未能达到主要终点，PEGPH20联合吉西他滨、白蛋白结合型紫杉醇治疗组相比单独使用吉西他滨、白蛋白结合型紫杉醇对照组mOS未见明显改善。经历挫折重整后，Halozyme公司快速调整战略，利用专有的ENHANZE技术平台优势赋能合作伙伴，在收取授权费用的同时，以在合作开发管线达到里程碑或上市后收取源源不断的分成费用。公司收入角度来看，Halozyme从2014年开始产生特许权使用费收入，2021年以前一直徘徊在1亿美元以内，而2021-2023年公司此项收入为2.04亿美元、3.6亿美元和4.48亿美元，呈现逐年稳步上升的态势。从下表也可以看出，与Halozyme合作并成功推动产品上市的有多家巨头，包括罗氏、强生、武田、Teva等，合作的产品包括前面提到的T药皮下注射版、达雷妥尤单抗皮下注射版、利妥昔单抗皮下注射版等等。图片来源：瞪羚社 Halozyme能够取得如此迅猛的业绩成长，很大程度是与“强生大哥”达雷妥尤单抗的相互成就，2019-2023年其销售分别为29.98亿美元、41.9亿美元、60.23亿美元、79.77亿美元和97.44亿美元（达雷妥尤单抗皮下注射剂型2020年上市）。据Halozyme和强生的口径，达雷妥尤单抗取得迅猛增长，皮下注射剂型（DARZALEX FASPRO）的上市功不可没，其在上市后迅速被市场接受，市场份额不断攀升。据强生在2022年中的一场电话会上表示，在美国、欧洲市场，达雷妥尤静脉注射到皮下注射的转换率分别达到了85%、80%。尽管达雷妥尤单抗的专利在2026年到期，Halozyme合作管线中仍有重磅炸弹潜力产品，如Argenx的艾加莫德，有望对冲收入下降的风向。 <03> 潜力药物通过皮下注射取得优势展望未来，可以预见不少重磅药物可能通过率先开发皮下注射剂型取得市场优势。海外潜在重磅炸弹中，最典型的案例莫过于强生的埃万妥单抗，近日公布的PALOMA-3试验结果显示（418位接受奥希替尼和铂类化疗治疗后或期间出现进展的EGFR突变晚期NSCLC患者），接受皮下和静脉组的ORR分别为30%和33%，中位PFS分别为6.1和4.3个月。同时皮下组与静脉组相比，OS更长，较少患者出现输注相关反应（13%vs 66%）和静脉血栓栓塞（9%vs 14%）。皮下注射版埃万妥单抗不仅在剂型上对静脉版埃万妥单抗取得优势，PALOMA-3数据表明皮下注射版埃万妥单抗同样具备疗效和安全性上的优势，这为其日后冲击NSCLC一线治疗增添了筹码。回溯国内，康宁杰瑞/思路迪2021年11月上市的恩沃利单抗也是一个典型的案例，该药物是全球首款皮下注射PD-L1单抗，其具备常温下稳定、注射部位限制少、皮下注射给药便捷等优势。2022-2023年恩沃利单抗销售为5.67亿元、6.349亿元，作为国产第6款PD-(L)1药物，能够在内卷的环境下第一年取得如此商业化成绩，除了其获批的适应症微卫星高度不稳定（MSI-H）或错配修复基因缺陷型（dMMR）不限瘤种的特殊性外，皮下注射剂型的优势功不可没。国内不乏有大胆尝试的Biotech，一旦做出来便能取得“王炸”效果。比如来凯医药，其率先在自主研发的LAE102的一期临床设计中加入皮下注射的给药方式，一方面其作为“减脂增肌”药物方便与GLP-1联用，另一方面也能够对比其与静脉注射的优劣，而全球ActRIIA这类靶点药物给药采用皮下注射，来凯医药还是第一家，若能够取得良好结果，那么很可能是差异化的同类首创。另一个案例是康宁杰瑞，其率先试验HER2双抗ADC与PD-L1抑制剂组成的高浓度皮下注射复方制剂JSKN033，其首次人体临床数据入选了2024 SITC，是IO+ADC首次皮下注射的全新尝试。该数据显示：10例疗效可评估患者中，3例患者出现部分缓解，5例患者疾病稳定，疾病控制率（DCR）达80%；安全性方面，最常见的治疗相关不良事件是1级注射部位反应，同时未观察到剂量限制性毒性。结语：K药皮下注射剂型的成功，给一众Biotech甚至MNC打开了全新的思路，一个小小的剂型改变，其带来的差异化优势有时候无可估量。日后，Biotech们在抗体药物开发层面大概率会更加重视皮下剂型，从而潜移默化实现肿瘤、自免药物的给药方式的变革。来源 | 瞪羚社（药智网获取授权转载）撰稿 | Kris. 责任编辑 | 八角声明：本文系药智网转载内容，图片、文字版权归原作者所有，转载目的在于传递更多信息，并不代表本平台观点。如涉及作品内容、版权和其它问题，请在本平台留言，我们将在第一时间删除。商务合作 | 王存星 19922864877（同微信）阅读原文，是受欢迎的文章哦

ICR study finds way to determine efficacy of experimental breast cancer drugs

Researchers at The Institute of Cancer Research (ICR), London, have discovered a way to use a simple, non-invasive MRI scan to determine whether an experimental approach to enhance treatment for breast cancer is effective. New research from the study, funded by Cancer Research UK, could help doctors visualise tumours and speed up the development of targeted therapies for breast cancer. If successful, these drugs could enhance the effectiveness of other drugs administered in combination. Common features of breast cancer include excessive connective tissue, which consists of cells and fibres that provide a scaffold, known as the extracellular matrix (ECM), where tumours can grow. Hyaluronic acid, which works by absorbing water, is naturally present inside the tumour ECM and causes cancer tumours to swell, making it challenging for drugs to penetrate, reach and destroy cancer cells. Researchers are able to use experimental drugs that target and degrade a chemical called hyaluronic acid to dissolve some of the dense ECM and improve drug delivery to tumours. However, when using experimental drugs targeting the chemical in this way, it can be difficult for researchers to identify the exact time when the acid has been degraded, and therefore, it is a challenge to determine the best time to administer other drugs. The researchers performed multi-parametric MRI scans on mice with breast tumours to track the efforts of PEGPH20, an investigational drug targeting hyaluronic acid, to gain measurements that provide additional information about the tissue being analysed. Study leader, Simon Robinson, professor, magnetic resonance imaging of cancer, ICR, London, said: "Diffusion-weighted MRI can be performed on conventional clinical MRI scanners. Our new research shows that we can use such scans to check if [experimental] drugs like PEGPH20 are working, helping guide treatment in a more targeted and non-invasive way." For example, after using diffusion-weighted imaging to understand how water molecules moved within tissue, the researchers found that a measurement of water’s ability to move or spread, called the apparent diffusion coefficient (ADC), was reduced by up to 38% following administration of PEGPH20. The results suggest that PEGPH20 could make breast cancer tissue more accessible to chemotherapy drugs and could potentially improve treatment outcomes. Upon further necessary testing, the researchers hope to improve the development of targeted therapies for breast cancer and potentially other tumours.
