Sacituzumab govitecan (SG) significantly improved progression-free survival (PFS) and overall survival (OS) versus chemotherapy in hormone receptor-positive human epidermal growth factor receptor 2-negative (HR+HER2) metastatic breast cancer (mBC) in the global TROPiCS-02 study. TROPiCS-02 enrolled few Asian patients. Here we report results of SG in Asian patients with HR+HER2 mBC from the EVER-132-002 study. Patients were randomized to SG (n = 166) or chemotherapy (n = 165). The primary endpoint was met: PFS was improved with SG versus chemotherapy (hazard ratio of 0.67, 95% confidence interval 0.52–0.87; P = 0.0028; median 4.3 versus 4.2 months). OS also improved with SG versus chemotherapy (hazard ratio of 0.64, 95% confidence interval 0.47–0.88; P = 0.0061; median 21.0 versus 15.3 months). The most common grade ≥3 treatment-emergent adverse events were neutropenia, leukopenia and anemia. SG demonstrated significant and clinically meaningful improvement in PFS and OS versus chemotherapy, with a manageable safety profile consistent with prior studies. SG represents a promising treatment option for Asian patients with HR+HER2 mBC (ClinicalTrials.gov identifier no. NCT04639986).

在全球 TROPiCS-02 研究中,对于激素受体阳性的人表皮生长因子受体 2 阴性(HR+HER2-)转移性乳腺癌(mBC),与化疗相比,萨妥珠单抗戈维替康(SG)能显著改善无进展生存期(PFS)和总生存期(OS)。TROPiCS-02 只招募了少数亚洲患者。在此,我们报告EVER-132-002研究中SG治疗HR+HER2-mBC亚洲患者的结果。患者随机接受 SG(166 人)或化疗(165 人)。研究达到了主要终点:SG与化疗相比,PFS有所改善(危险比为0.67,95%置信区间为0.52-0.87;P=0.0028;中位4.3个月与4.2个月)。SG与化疗相比,OS也有所改善(危险比为0.64,95%置信区间为0.47-0.88;P = 0.0061;中位21.0个月对15.3个月)。最常见的≥3级治疗突发不良事件是中性粒细胞减少、白细胞减少和贫血。与化疗相比,SG明显改善了PFS和OS,且具有临床意义,其安全性与之前的研究一致。对于亚洲的HR+HER2- mBC患者来说,SG是一种很有前景的治疗选择(ClinicalTrials.gov标识符编号:NCT04639986)。

Repeat expansion disorders (REDs) are a devastating group of predominantly neurological diseases. Together they are common, affecting 1 in 3,000 people worldwide with population-specific differences. However, prevalence estimates of REDs are hampered by heterogeneous clinical presentation, variable geographic distributions and technological limitations leading to underascertainment. Here, leveraging whole-genome sequencing data from 82,176 individuals from different populations, we found an overall disease allele frequency of REDs of 1 in 283 individuals. Modeling disease prevalence using genetic data, age at onset and survival, we show that the expected number of people with REDs would be two to three times higher than currently reported figures, indicating underdiagnosis and/or incomplete penetrance. While some REDs are population specific, for example, Huntington disease-like 2 in Africans, most REDs are represented in all broad genetic ancestries (that is, Europeans, Africans, Americans, East Asians and South Asians), challenging the notion that some REDs are found only in specific populations. These results have worldwide implications for local and global health communities in the diagnosis and counseling of REDs. Repeat expansion disorders are found in all major global populations, and their frequency is up to three times higher than typically quoted, suggesting underdiagnosis or incomplete penetrance.
重复扩展障碍(REDs)是一组以神经系统疾病为主的破坏性疾病。这些疾病很常见,全球每 3,000 人中就有 1 人患病,但因人群而异。然而,由于临床表现不尽相同、地理分布各异以及技术限制,REDs 的患病率估算受到了阻碍,导致估算不足。在此,我们利用来自不同人群的 82176 个个体的全基因组测序数据,发现 REDs 的总体疾病等位基因频率为每 283 个个体中有 1 个。我们利用基因数据、发病年龄和存活率对疾病流行率进行建模,结果表明,REDs 患者的预期人数将比目前报告的数字高出两到三倍,这表明诊断不足和/或渗透不完全。虽然有些 REDs 具有人群特异性,例如非洲人中的亨廷顿病 2 型,但大多数 REDs 在所有广泛的遗传血统(即欧洲人、非洲人、美国人、东亚人和南亚人)中都有体现,这对某些 REDs 只出现在特定人群中的观点提出了质疑。这些结果对当地和全球卫生界诊断和咨询 REDs 具有世界性的影响。

Neoantigen immunoediting drives immune checkpoint blockade efficacy, yet the molecular features of neoantigens and how neoantigen immunogenicity shapes treatment response remain poorly understood. To address these questions, 80 patients with non-small cell lung cancer were enrolled in the biomarker cohort of CheckMate 153 (CA209-153), which collected radiographic guided biopsy samples before treatment and during treatment with nivolumab. Early loss of mutations and neoantigens during therapy are both associated with clinical benefit. We examined 1,453 candidate neoantigens, including many of which that had reduced cancer cell fraction after treatment with nivolumab, and identified 196 neopeptides that were recognized by T cells. Mapping these neoantigens to clonal dynamics, evolutionary trajectories and clinical response revealed a strong selection against immunogenic neoantigen-harboring clones. We identified position-specific amino acid and physiochemical features related to immunogenicity and developed an immunogenicity score. Nivolumab-induced microenvironmental evolution in non-small cell lung cancer shared some similarities with melanoma, yet critical differences were apparent. This study provides unprecedented molecular portraits of neoantigen landscapes underlying nivolumab’s mechanism of action. In this biomarker cohort analysis of CheckMate 153, analyses of genomic alterations and neoepitope immunogenicity in tumor tissue samples from patients with non-small cell lung cancer treated with nivolumab show the evolution of neoantigens during nivolumab-induced selection pressure and how it associates with clinical response.
新抗原免疫编辑推动了免疫检查点阻断疗法的疗效,但人们对新抗原的分子特征以及新抗原免疫原性如何影响治疗反应仍知之甚少。为了解决这些问题,CheckMate 153(CA209-153)的生物标志物队列招募了80名非小细胞肺癌患者,该队列收集了治疗前和使用nivolumab治疗期间的放射引导活检样本。治疗期间的早期突变丢失和新抗原都与临床获益相关。我们研究了 1,453 个候选新抗原,其中包括许多在使用 nivolumab 治疗后癌细胞数量减少的新抗原,并确定了 196 个可被 T 细胞识别的新肽。将这些新抗原与克隆动态、进化轨迹和临床反应进行映射,发现了针对具有免疫原性的新抗原载体克隆的强烈选择。我们确定了与免疫原性相关的特定位置氨基酸和理化特征,并制定了免疫原性评分。Nivolumab诱导的非小细胞肺癌微环境演变与黑色素瘤有一些相似之处,但也有明显的关键差异。这项研究为 nivolumab 的作用机制提供了前所未有的新抗原分子图谱。

Chronic kidney disease (CKD) is associated with a substantial risk of progression to end-stage renal disease and vascular events. The nonsteroidal mineralocorticoid receptor antagonist (MRA), finerenone, offers cardiorenal protection for people with CKD and diabetes, but there is uncertainty if the steroidal MRA, spironolactone, provides the same protection. In this prospective, randomized, open, blinded endpoint trial, we assessed the effectiveness of 25 mg spironolactone in addition to usual care or usual care alone for reducing cardiovascular outcomes in stage 3b CKD among an older community cohort (mean age = 74.8 years and s.d. = 8.1). We recruited 1,434 adults from English primary care, of whom 1,372 (96%) were included in the primary analysis. The primary outcome was time from randomization until the first occurrence of death, hospitalization for heart disease, stroke, heart failure, transient ischemic attack or peripheral arterial disease, or first onset of any condition listed not present at baseline. Across 3 years of follow-up, the primary endpoint occurred in 113 of 677 participants randomized to spironolactone (16.7%) and 111 of 695 participants randomized to usual care (16.0%) with no significant difference between groups (hazard ratio = 1.05, 95% confidence interval: 0.81–1.37). Two-thirds of participants randomized to spironolactone stopped treatment within 6 months, predominantly because they met prespecified safety stop criteria. The most common reason for stopping spironolactone was a decrease in the estimated glomerular filtration rate that met prespecified stop criteria (n = 239, 35.4%), followed by participants being withdrawn due to treatment side effects (n = 128, 18.9%) and hyperkalemia (n = 54, 8.0%). In conclusion, we found that spironolactone was frequently discontinued due to safety concerns, with no evidence that it reduced cardiovascular outcomes in people with stage 3b CKD. Spironolactone should not be used for people with stage 3b CKD without another explicit treatment indication. ClinicalTrials.gov registration: ISRCTN44522369.

慢性肾脏病(CKD)与进展为终末期肾脏病和血管事件的巨大风险相关。非甾体类矿物皮质激素受体拮抗剂(MRA)非诺酮能为 CKD 和糖尿病患者提供心肾保护,但甾体 MRA 螺内酯能否提供同样的保护尚不确定。在这项前瞻性、随机、开放、盲点试验中,我们评估了 25 毫克螺内酯在常规治疗或单独常规治疗的基础上降低 3b 期慢性肾脏病社区老年人群(平均年龄 = 74.8 岁,s.d. = 8.1)心血管后果的效果。我们从英国初级医疗机构招募了 1,434 名成年人,其中 1,372 人(96%)被纳入主要分析。主要研究结果为从随机抽样到首次死亡、因心脏病、中风、心力衰竭、短暂性脑缺血发作或外周动脉疾病住院,或首次出现基线时未列出的任何病症的时间。在3年的随访中,随机接受螺内酯治疗的677名参与者中有113人(16.7%)出现了主要终点,随机接受常规治疗的695名参与者中有111人(16.0%)出现了主要终点,组间无显著差异(危险比=1.05,95%置信区间:0.81-1.37)。三分之二随机接受螺内酯治疗的参与者在6个月内停止了治疗,主要是因为他们达到了预先规定的安全停药标准。停止使用螺内酯最常见的原因是估计肾小球滤过率下降,且符合预先设定的停止标准(239 人,35.4%),其次是因治疗副作用(128 人,18.9%)和高钾血症(54 人,8.0%)而退出治疗。总之,我们发现螺内酯经常因安全性问题而停药,但没有证据表明它能降低 3b 期慢性肾脏病患者的心血管预后。如果没有其他明确的治疗指征,3b 期慢性肾脏病患者不应使用螺内酯。ClinicalTrials.gov 注册:ISRCTN44522369。

Living longer and healthier boosts individual and family welfare. As part of the World Bank’s Healthy Longevity Initiative, we quantified the economic value of achieving the highest possible life span. We estimated the economic value of reducing avoidable mortality, defined as the difference between observed (or projected) mortality and lowest achieved (or projected) mortality, by world regions, sex, and age, between 2000 and 2021, with projection to 2050. In 2019, 69% of mortality, or 40 million deaths, was avoidable. The economic value of avoidable mortality globally was 23% of annual income, meaning that, globally, populations would be willing to give up about one-fifth of their current income in exchange for a year living at the lowest achieved mortality rate. This value ranges from 19% in China to 34% in sub-Saharan Africa. Under the rapid-progress scenario, in which countries experience fast but plausible mortality reductions from 2019 to 2050, we would expect globally the gap between projected and frontier life expectancy to be halved by 2050, and the economic value after achieving this scenario is equivalent to 14% of annual income. Our work provides supportive evidence on the high economic value placed on improving health. Forming the recommendations of the World Bank’s Healthy Longevity Initiative, this analysis finds that the economic impact of avoidable mortality globally is equivalent to 23% of the annual income.
更长寿、更健康的生活可提高个人和家庭的福利。作为世界银行 "健康长寿倡议 "的一部分,我们量化了实现尽可能长寿的经济价值。我们估算了降低可避免死亡率的经济价值,可避免死亡率的定义是 2000 年至 2021 年期间,按世界地区、性别和年龄划分的观察到的(或预测的)死亡率与达到的(或预测的)最低死亡率之间的差异,并预测到 2050 年。2019 年,69% 的死亡率,即 4000 万例死亡是可以避免的。全球可避免死亡率的经济价值为年收入的 23%,这意味着全球人口愿意放弃约五分之一的现有收入,以换取一年以最低死亡率生活。这个数值从中国的 19% 到撒哈拉以南非洲的 34% 不等。在快速进展情景下,即从 2019 年到 2050 年,各国的死亡率会快速但合理地降低,我们预计到 2050 年,全球预计寿命与前沿寿命之间的差距将缩小一半,实现这一情景后的经济价值相当于年收入的 14%。我们的工作为提高健康水平带来的高经济价值提供了支持性证据。

Acute myeloid leukemia (AML) is a rapidly progressive malignancy without effective therapies for refractory disease. So far, chimeric antigen receptor (CAR) T cell therapy in AML has not recapitulated the efficacy seen in B cell malignancies. Here we report a pilot study of autologous anti-CD123 CAR T cells in 12 adults with relapsed or refractory AML. CAR T cells targeting CD123+ cells were successfully manufactured in 90.4% of runs. Cytokine release syndrome was observed in 10 of 12 infused individuals (83.3%, 90% confidence interval 0.5–0.97). Three individuals achieved clinical response (25%, 90% confidence interval 0.07–0.53). We found that myeloid-supporting cytokines are secreted during cell therapy and support AML blast survival via kinase signaling, leading to CAR T cell exhaustion. The prosurvival effect of therapy-induced cytokines presents a unique resistance mechanism in AML that is distinct from any observed in B cell malignancies. Our findings suggest that autologous CART manufacturing is feasible in AML, but treatment is associated with high rates of cytokine release syndrome and relatively poor clinical efficacy. Combining CAR T cell therapies with cytokine signaling inhibitors could enhance immunotherapy efficacy in AML and achieve improved outcomes (ClinicalTrials.gov identifier: NCT03766126).

急性髓性白血病(AML)是一种进展迅速的恶性肿瘤,对难治性疾病没有有效的治疗方法。迄今为止,嵌合抗原受体(CAR)T细胞疗法在急性髓细胞性白血病中的疗效尚未达到B细胞恶性肿瘤的水平。在此,我们报告了一项在12名复发或难治性急性髓细胞性白血病成人患者中开展的自体抗CD123 CAR T细胞试验研究。90.4%的实验成功制造出了靶向CD123+细胞的CAR T细胞。12名输注者中有10人观察到细胞因子释放综合征(83.3%,90%置信区间为0.5-0.97)。有 3 人获得了临床反应(25%,90% 置信区间为 0.07-0.53)。我们发现,细胞治疗过程中会分泌支持髓系的细胞因子,并通过激酶信号支持急性髓细胞白细胞的存活,从而导致 CAR T 细胞衰竭。治疗诱导的细胞因子的促存活效应为急性髓细胞性白血病提供了一种独特的抵抗机制,这种机制不同于在 B 细胞恶性肿瘤中观察到的任何机制。我们的研究结果表明,自体 CART 治疗在急性髓细胞性白血病中是可行的,但治疗过程中细胞因子释放综合征的发生率较高,临床疗效相对较差。将CAR T细胞疗法与细胞因子信号转导抑制剂相结合,可以提高急性髓细胞性白血病的免疫疗法疗效并改善预后(ClinicalTrials.gov标识符:NCT03766126)。

With population aging, national health systems face difficult trade-offs in allocating resources. The World Bank launched the Healthy Longevity Initiative to generate evidence for investing in policies that can improve healthy longevity and human capital. As part of this initiative, we quantified the economic value of reducing avoidable mortality from major noncommunicable diseases and injuries. We estimated avoidable mortality—the difference between lowest-achieved mortality frontiers and projected mortality trajectories—for each cause of death, for 2000, 2019 and 2050, and for geographic regions, with high-income countries, India and China considered separately; we applied economic values to these estimates. The economic value of reducing cardiovascular disease avoidable mortality would be large for both sexes in all regions, reaching 2–8% of annual income in 2019. For cancers, it would be 5–6% of annual income in high-income countries and China, and for injuries, it would be around 5% in sub-Saharan Africa and Latin America and the Caribbean. Despite the large uncertainty surrounding our estimates, we offer economic values for reducing avoidable mortality by cause and metrics comparable to annual incomes, which enable multisectoral priority setting and are relevant for high-level policy discussions around budget and resource allocations. This study reports substantial economic value in annual income if mortality due to cardiovascular diseases, cancers and injuries is reduced.
随着人口老龄化的加剧,国家卫生系统在分配资源时面临着艰难的权衡。世界银行发起了 "健康长寿倡议"(Healthy Longevity Initiative),旨在为改善健康长寿和人力资本的政策投资提供证据。作为该倡议的一部分,我们量化了降低主要非传染性疾病和伤害导致的可避免死亡率的经济价值。我们估算了 2000 年、2019 年和 2050 年每种死因的可避免死亡率--最低死亡率前沿与预测死亡率轨迹之间的差值,并对高收入国家、印度和中国等地理区域进行了单独考虑;我们对这些估算值应用了经济价值。在所有地区,降低心血管疾病可避免死亡率的经济价值对男女两性来说都很大,2019 年将达到年收入的 2-8% 。就癌症而言,在高收入国家和中国,经济价值将达到年收入的 5-6%;就伤害而言,在撒哈拉以南非洲以及拉丁美洲和加勒比海地区,经济价值将达到 5%左右。尽管我们的估算存在很大的不确定性,但我们提供了按病因和与年收入相当的度量来降低可避免死亡率的经济价值,这有助于确定多部门的优先事项,并与围绕预算和资源分配的高层政策讨论相关。
