Abstract:

Background:

Hormone receptor‐positive (HR+)/humaal growth factor receptor 2‐negative (HER2‐) breast cancer, the most common breast cancer type, has variable prognosis and high recurrence risk. Neoadjuvant therapy is recommended for median‐high risk HR+/HER2‐ patients. This phase II, single‐arm, prospective study aimed to explore appropriate neoadjuvant treatment strategies for HR+/HER2‐ breast cancer patients.

Methods:

Eligible female patients with newly diagnosed, untreated HR+/HER2‐ breast cancer received 2 cycles of nab‐paclitaxel and carboplatin (nabPCb). Magnetic resonance imaging (MRI) was performed to assess tumor responses, and 40% regression of the maximal tumor diameter was deemed chemo‐sensitive. Chemo‐sensitive patients continued nabPCb for 4 more cycles (group A). Chemo‐insensitive patients were randomized to groups B, C, and D at a ratio of 1:3:1 to receive a new chemotherapy for 4 cycles or endocrine‐immune‐based therapy (dalpiciclib, letrozole and adebrelimab, with goserelin if patients were premenopausal) for 4 cycles or to undergo surgery. Peripheral blood and core‐needle biopsy (CNB) samples were collected before treatment, followed by a next‐generation sequencing (NGS) panel detection and similarity network fusion (SNF) typing through digital pathology data. The primary endpoint was the pathological complete response (pCR) rate, and the secondary endpoint was the clinical objective response rate (ORR).

Results:

A total of 121 patients were enrolled (67.8% with stage III disease), with 76, 9, 27, and 9 patients in groups A, B, C and D, respectively. The total pCR rate was 4.1%, and all patients who received pCR were in group A. Group C had a better ORR than Group B (81.5% vs. 66.7%). Exploratory analysis revealed that patients with the SNF4 subtype were the most sensitive to nabPCb (pCR rate of 21.1% vs. 1.8% in group A), whereas patients in group C with the SNF2 subtype were more sensitive to endocrine‐immune‐based therapy (Miller‐Payne grade 4‐5, 45.5% vs. 6.3%).

Conclusions:

Converting to endocrine‐immune‐based therapy improved the ORR, but not the pCR rate in chemo‐insensitive patients. Neoadjuvant chemotherapy and endocrine therapy are not mutually exclusive. The SNF4 subtype of HR+/HER2‐ breast cancer was more chemo‐sensitive, whereas the SNF2 subtype might be more sensitive to immunotherapy.

Influence of ethnicity on cyclin-dependent kinase inhibitor efficacy and toxicity: A systematic review and meta-analysis

Review

BACKGROUND:

The combination of cyclin-dependent kinase 4 and 6 inhibitors (CDK4/6i) with endocrine therapy (ET) is the standard of care for patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR+/HER2-) advanced breast cancer (aBC). While the efficacy and safety profiles of CDK4/6i and ET have been extensively evaluated in phase II and III trials worldwide, it remains unclear whether the response to CDK4/6i and toxicity profile vary among Asian and non-Asian patients. Therefore, we aimed to assess the treatment efficacy of ET with and without CDK4/6i by comparing outcomes in Asian and non-Asian subgroups included in these clinical trials. In addition, we evaluated the toxicity profiles of the treatments by estimating the risk of treatment-related adverse events (AEs).

METHODS:

We conducted a meta-analysis including the most recent randomized trial data systematically searched from PubMed, Embase, Web of Science, Cochrane CENTRAL (from inception to May 31st, 2024) or presented in abstracts or oral presentations at the ESMO, ASCO, and SABCS international congresses. We included studies comparing CDK4/6i (palbociclib, ribociclib, abemaciclib, dalpiciclib) + ET versus placebo + ET. Progression-free survival (PFS) and overall survival (OS), hazard ratios (HR), and 95 % confidence intervals (CI) were extracted for the two subgroups of interest. To evaluate the treatment-related toxicity profiles, we extracted the number of side effects to estimate the risk of treatment-emergent AEs.

RESULTS:

Eleven studies (n = 5129) were included in this meta-analysis. The addition of CDK4/6i to ET consistently improved PFS in both Asian (HR = 0.52, 95 % CI 0.47-0.60; p < 0.001) and non-Asian (HR = 0.58, 95 % CI 0.52-0.64; p < 0.001) groups. Similarly, the combination of CDK4/6i + ET led to an OS improvement in both Asian (HR = 0.75, 95 % CI 0.62-0.91; p = 0.003) and non-Asian (HR = 0.81, 95 % CI 0.73-0.89; p < 0.001) patients. The risk of treatment related toxicity was higher in the CDK4/6i + ET arm in both Asian and non-Asian groups. Interestingly, a numerically higher rate of treatment-related hematological toxicity was observed in Asian patients, although no significant interethnic difference was found in the relative risk of these events.

CONCLUSIONS:

The combination of CDK4/6i and ET significantly improves PFS and OS compared to ET alone in both Asian and non-Asian patients with HR+/HER2-aBC. Although the magnitude of benefit appears to be independent of ethnicity, future clinical trials should devise a standardized method for stratifying patients by ethnicity to more effectively assess potential differences in treatment benefits.

Elucidating Binding Selectivity in Cyclin-Dependent Kinases 4, 6, and 9: Development of Highly Potent and Selective CDK4/9 Inhibitors

Article

作者: Xing, Yajie ; Cao, Qixiong ; Chen, Jiean ; Wang, Rui ; Yang, Qianqian ; Pan, Shuqiong ; Feng, Meixi ; He, Zhipeng ; Huang, Yong ; Lian, Chenshan ; Jiang, Chenran ; Kang, Wei ; Yang, Jinglei ; Liu, Zhihong ; Yin, Feng ; Wu, Yun-Dong ; Ye, Yuxin ; Song, Chunli ; Zhao, Juan

CDK4/6 inhibitors are effective in treating HR⁺/HER2^- breast cancer but face limitations due to therapeutic resistance and hematological toxicity, particularly from strong CDK6 inhibition. To address these challenges, designing selective inhibitors targeting specific cyclin-dependent kinases (CDK) members could offer clinical advantages and broaden CDK inhibitor indications. However, the highly conserved binding pockets of CDKs complicate selective targeting. This study leverages in silico modeling and structural analysis of cocrystal data to identify subtle differences in key CDK binding pockets. Notably, a sequence difference in the αD-helix motif between CDK4 and CDK6 provides a targetable "sweet spot" for selectivity. By incorporating a 1,4-trans-cyclohexanediamine side chain, we designed molecules that favor interactions with CDK4 over CDK6 and explored potential dual CDK4/9 inhibition. This approach yielded a lead compound with distinct in vitro selectivity and promising in vivo pharmacokinetics, offering valuable insights for the development of selective next-generation CDK inhibitors.

IF: 20.1Tibremciclib or Placebo Plus Fulvestrant in Hormone Receptor-Positive and ERBB2-Negative Advanced Breast Cancer After Endocrine Therapy: A Randomized Clinical Trial.Tao Z, Zhang J, Zheng Q, Wang Y, Cai L, Xu H, Xu X, Kong X, Ding S, Hao C, Wang H, Zong H, Jin X, Wang X, Li Y, Yang X, Li W, Du X, Chen H, Wu P, Li P, Mao L, Ding L, Hu X, Wang S.Fudan University Shanghai Cancer Center, Shanghai, China; Shanghai Medical College, Fudan University, Shanghai, China; Sun Yat-sen University Cancer Center, Guangzhou, China; Shandong Cancer Hospital, Jinan, China; Harbin Medical University Cancer Hospital, Harbin, China; Weihai Municipal Hospital, Weihai, China; Yichang Central People's Hospital, Yichang, China; Xingtai People's Hospital, Xingtai, China; The Central Hospital of Yongzhou, Yongzhou, China; Tianjin Medical University Cancer Center Institute and Hospital, Tianjing, China; Sichuan Cancer Hospital, Chengdu, China; The First Affiliated Hospital of Zhengzhou Hospital, Zhengzhou, China; The First Affiliated Hospital of Bengbu Medical College, Bengbu, China; The First Affiliated Hospital of Henan University of Science and Technology, Luoyang, China; The First Affiliated Hospital of Guangxi Medical University, Nanning, China; The First Affiliated Hospital of Nanyang Medical College, Nanyang, China; Betta Pharmaceuticals Co, Ltd, Hangzhou, China.QUESTION: Does the addition of tibremciclib to fulvestrant prolong progression-free survival (PFS) for patients with hormone receptor-positive (HR+) and ERBB2 (formerly HER2)-negative (ERBB2-) advanced breast cancer (ABC) who experienced progression while receiving prior endocrine therapy (ET)?FINDINGS: This phase 3 randomized clinical trial involved 274 patients with HR+/ERBB2- ABC who experienced progression while receiving prior ET. The combination of tibremciclib and fulvestrant significantly improved PFS compared with the combination of placebo plus fulvestrant; the median PFS was 16.5 (95% CI, 12.8-16.6) months in the tibremciclib arm, and the toxic effects were tolerable.MEANING: The results of this trial suggest that tibremciclib plus fulvestrant provides improvement in PFS for patients with HR+/ERBB2-ABC who experienced progression after ET, with a manageable safety profile.IMPORTANCE: Cyclin-dependent kinase (CDK) 4/6 inhibitors combined with endocrine therapy (ET) are now considered the standard treatment regimen for hormone receptor-positive (HR+) and ERBB2 (formerly HER2)-negative (ERBB2-) advanced breast cancer (ABC). Tibremciclib (BPI-16350), a novel CDK4/6 inhibitor, has demonstrated favorable tolerability and promising antitumor activity as a monotherapy or combined with fulvestrant among patients with HR+/ERBB2- ABC in a phase 1 trial. Further investigations are necessary to assess the efficacy and safety of tibremciclib.OBJECTIVE: To compare tibremciclib plus fulvestrant and placebo plus fulvestrant in terms of efficacy and safety among patients with HR+/ERBB2- ABC who exhibited disease progression after ET.DESIGN, SETTING, AND PARTICIPANTS: The TIFFANY trial was a double-blind, placebo-controlled, phase 3 randomized clinical trial of patients with HR+/ERBB2- ABC who had experienced progression while receiving prior ET and had received no more than 1 line of chemotherapy. This trial was conducted at 69 Chinese centers between May 25, 2022, and April 25, 2023. The data cutoff date for this analysis was March 31, 2024.INTERVENTIONS: Patients were randomly assigned to receive tibremciclib (400 mg, orally, once daily) plus fulvestrant or placebo plus fulvestrant at a 2:1 ratio until disease progression, death, or treatment discontinuation for various reasons.MAIN OUTCOMES AND MEASURES: The primary end point was investigator-assessed progression-free survival (PFS), and the secondary end points included the objective response rate, overall survival, and safety.RESULTS: A total of 274 female patients (median [IQR] age, 53.0 [46.0-60.0] years) were randomly assigned to receive tibremciclib plus fulvestrant (184 [67.2%]) or placebo plus fulvestrant (90 [32.8%]). Among these patients, 144 PFS events occurred (80 in the tibremciclib arm and 64 in the placebo arm), with a median follow-up of 12.9 months for both arms. Tibremciclib plus fulvestrant significantly improved PFS compared with placebo plus fulvestrant (median, 16.5 months [95% CI, 12.8-16.6] vs 5.6 months [95% CI, 4.5-9.2]; hazard ratio, 0.37; 95% CI, 0.27-0.52; P < .001). In patients with measurable disease, tibremciclib plus fulvestrant achieved an objective response rate of 45.6% (95% CI, 37.6%-53.7%) compared with 12.9% (95% CI, 6.1%-23.0%) in the placebo arm (P < .001). The most common grade 3 or higher treatment-emergent adverse events in the tibremciclib vs placebo arm were neutropenia (15.2% vs 5.6%, respectively), anemia (12.0% vs 4.4%, respectively), and hypokalemia (12.0% vs 0%, respectively). No drug-related deaths occurred in the tibremciclib arm, and 1 death occurred in the placebo arm.CONCLUSIONS AND RELEVANCE: The results of this randomized clinical trial suggest that tibremciclib plus fulvestrant was associated with statistically significant and clinically meaningful improvements in PFS compared with placebo plus fulvestrant. Furthermore, tibremciclib plus fulvestrant demonstrated a manageable safety profile in patients with HR+/ERBB2- ABC who experienced progression while receiving prior ET.TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05433480PMID: 40742733DOI: 10.1001/jamaoncol.2025.2092ESMO Open. 2025 Jun;10(6):105121.

This phase I, first-in-human study assessed the tibremciclib monotherapy and combined with fulvestrant in advanced breast cancer (ABC).PATIENTS AND METHODS: This open-label, phase I study (NCT03791112) comprised dose escalation (phase Ia) and expansion (phase Ib). In phase Ia, Chinese patients with advanced solid tumors received tibremciclib monotherapy (50-500 mg orally once daily). Based on the tolerability and preliminary antitumor activity from phase Ia, two dose cohorts (300 or 400 mg orally once daily) were selected in phase Ib to combine with fulvestrant in patients with hormone receptor (HR)-positive/human epidermal growth receptor 2 (HER2)-negative ABC who failed endocrine therapy. The primary endpoints were safety and tolerability, and secondary endpoints included pharmacokinetics (PK) and antitumor activity.RESULTS: In phase Ia, 24 patients with advanced tumors (23 ABC and 1 abdominal liposarcoma) received tibremciclib monotherapy, while in phase Ib, 78 patients with HR-positive/HER2-negative stage IV ABC received tibremciclib plus fulvestrant, with a median age of 56.0 (range 26-66) years and 53.5 (range 33-71) years, respectively. In phase Ia, one dose-limiting toxicity (grade 3 blood creatinine increased) occurred at 500 mg and the maximum tolerated dose was not reached. In phase Ib, the recommended phase II dose (RP2D) was tibremciclib 400 mg plus fulvestrant 500 mg. Frequently reported treatment-emergent adverse events of any grade were grade 1-2 blood creatinine increased, hypertriglyceridemia, and anemia. PK demonstrates dose proportionality, a half-life of ~35.9-51.1 h, and no drug-drug interaction with fulvestrant. In phase Ia, one patient achieved partial response (PR), with a confirmed objective response rate (ORR) of 4.2% and a disease control rate (DCR) of 70.8%. In phase Ib, 42 patients achieved PR, with an ORR of 53.8% and a DCR of 87.2%.CONCLUSIONS: Tibremciclib monotherapy or combined with fulvestrant was well tolerated with the RP2D set at 400 mg plus fulvestrant 500 mg. PK was consistent with dose proportionality. Both regimens showed preliminary antitumor activity in patients with HR-positive/HER2-negative ABC, supporting further evaluation in a phase III study (NCT05433480).KEYWORDS: breast cancer; cyclin-dependent kinase 4 and 6; fulvestrant; safety; tibremciclibPMID: 40403388DOI: 10.1016/j.esmoop.2025.105121（来源：SIBCS）声明凡署名原创的文章版权属《肿瘤瞭望》所有，欢迎分享、转载。本文仅供医疗卫生专业人士了解最新医药资讯参考使用，不代表本平台观点。该等信息不能以任何方式取代专业的医疗指导，也不应被视为诊疗建议，如果该信息被用于资讯以外的目的，本站及作者不承担相关责任。

宋传贵教授：ASCO年会乳腺癌新辅助治疗——聚焦升阶梯与降阶梯治疗新进展与未来发展趋势

点击上方蓝字关注我们编者按：由广东省预防医学会主办，广东省人民医院协办的2025广东省预防医学会乳腺癌防治专业委员会学术研讨会日前于广州圆满落幕。复旦大学附属肿瘤医院福建医院（福建省肿瘤医院）宋传贵教授在本次会议上带来了“2025 ASCO乳腺癌新辅助治疗进展”的讲课，会后，肿瘤瞭望特邀采访了宋传贵教授，请他就2025年ASCO年会新辅助治疗研究的整体趋势及相关进展进行了介绍。01《肿瘤瞭望》：2025年ASCO年会中，乳腺癌新辅助治疗领域有多项突破性研究成果公布，尤其是降阶梯治疗、靶向联合方案等议题备受关注。王坤教授公布的neoCARHP研究结果显示，THP方案在HER2阳性早期乳腺癌治疗中达到非劣效于含卡铂（TCbHP）方案的pCR率，且安全性更优。您如何评价这一结果对临床实践的影响？作为国内乳腺癌领域专家，请您为我们总结下2025年ASCO年会新辅助治疗研究的整体趋势。宋传贵教授复旦大学附属肿瘤医院福建医院（福建省肿瘤医院）众所周知，HER2阳性早期乳腺癌新辅助治疗，已经形成了靶向联合化疗的治疗模式。目前，HER2阳性早期乳腺癌患者新辅助治疗的pCR率可以达到60%甚至更高，但当今临床治疗的关键点在于，如何减轻乳腺癌患者药物治疗带来的毒性，同时保持治疗疗效。广东省人民医院王坤教授在2025年ASCO大会带来了HER2阳性早期乳腺癌新辅助治疗的neoCARHP研究，结果显示，THP方案pCR率非劣效于TCbHP方案（64.1% vs 65.9%）。目前来看，对于铂类添加与否，临床一直存在争议，最近公布的多项临床研究也证实，“去铂类”其实并不影响患者整体的pCR率，同时又能减少铂类带来的血液学和消化道等不良反应。△neoCARHP研究pCR率未来，对于HER2阳性乳腺癌的新辅助治疗，更多的是朝着“降阶梯”治疗的方向发展，无论是“去铂类”还是缩短新辅助治疗的疗程（降低治疗强度），甚至未来可能实现应用单一的ADC药物来代替现有的三药/四药联合治疗方案，以上这些均代表了未来以更少的药物来争取相似或者更好的治疗疗效，同时减少多药化疗引起的不良反应的发展趋势。目前新辅助治疗研究不止于此。尽管现在许多新辅助治疗研究仍以pCR为主要研究终点，但可以看到一个趋势，即大家越来越关注长期生存，因此很多研究以iDFS甚至OS作为主要研究终点，这类研究更能体现我们对乳腺癌患者全程治疗的关注。当前的临床研究多聚焦于ADC药物，由此可见，我们对ADC药物治疗还是充满期待的。复旦大学附属肿瘤医院李俊杰教授在2024年SABCS大会上报告的FASCINATE-N研究结果显示，SHR-A1811单药治疗HER2阳性早期乳腺癌的疗效与多药联合取得的pCR率相当。未来，他们还会进行更长时间随访，若能证明SHR-A1811单药对长期预后的结果相似，或将改变当前临床实践。当然，目前我们不能简单认为一项或少数几项研究数据就能改变当前临床实践，因为需要根据研究中的入组人群进一步区分。若“去卡铂”药物方案可行，目前可能仅在相对早期患者中试用，想要大规模运用可能还需等待时机，但这至少也是“降阶梯”治疗进步的表现。此外，今年ASCO年会上WSG的联合分析等研究数据公布，也体现了这一趋势，让我们对目前新辅助治疗的理解更进一步。02《肿瘤瞭望》：DAWNA-A研究证实，达尔西利联合内分泌治疗可显著改善HR+/HER2-高危早期乳腺癌患者的无浸润性疾病生存期（iDFS）。您如何看待CDK4/6抑制剂从晚期治疗向辅助治疗的延伸？宋传贵教授复旦大学附属肿瘤医院福建医院（福建省肿瘤医院）事实上，对于乳腺癌患者的治疗，不同分子亚型患者所运用的治疗策略是不一样的，一些患者需要进行“降阶梯”治疗，而另一些患者则需要“升阶梯”治疗。如对于HR+乳腺癌患者，我们是否需要在传统内分泌治疗的基础上进行“加码”？现在多项相关研究结果的公布，也使患者的治疗之路越来越清晰，治疗选择也越来越多样化。以高危HR+早期乳腺癌患者治疗为例，这类患者的复发风险主要存在于第二个5年，我们不仅要强调对于绝经前或者围绝经期患者的卵巢功能抑制，同时也会在患者内分泌治疗强度和时间上给予相应调整。如对于早期高危患者我们会在OFS+内分泌基础上联合CDK4/6抑制剂或者适当延长患者内分泌治疗的时间（内分泌治疗时间可延长至10年）。从monarchE研究到NATELEE研究，再到2025年ASCO年会上邵志敏教授报道的DAWNA-A研究，均证明了CDK4/6抑制剂联合内分泌治疗能使乳腺癌患者的生存期延长。DAWNA-A研究更是基于中国患者人群数据，入组了超过5000例患者的数据，结果证实，达尔西利+内分泌治疗相较于安慰剂+内分泌治疗有更多的生存获益（2年iDFS达尔西利组94.7% vs安慰剂组90.2%，HR=0.56（0.43-0.71），P＜0.0001）。△DAWNA-A研究iDFSCDK4/6抑制剂在HR+早期乳腺癌患者治疗中的适应症获批，对于早期高危乳腺癌患者而言，治疗选择增多的同时，也能使其复发和转移风险下降，能为患者争取更多的治疗希望和治愈空间。因此，我们对DAWNA-A研究也充满了更多期待。宋传贵教授复旦大学附属肿瘤医院福建医院（福建省肿瘤医院）主任医师、教授、博士生导师乳腺肿瘤学科带头人/乳腺肿瘤诊治中心执行主任中国抗癌协会乳腺癌专业委员会常委中国抗癌协会肿瘤靶向治疗专委会常委福建省抗癌协会乳腺癌专业委员会主任委员中华医学会肿瘤分会乳腺肿瘤学组成员CSCO乳腺癌专家委员会委员（来源：《肿瘤瞭望》编辑部）声明凡署名原创的文章版权属《肿瘤瞭望》所有，欢迎分享、转载。本文仅供医疗卫生专业人士了解最新医药资讯参考使用，不代表本平台观点。该等信息不能以任何方式取代专业的医疗指导，也不应被视为诊疗建议，如果该信息被用于资讯以外的目的，本站及作者不承担相关责任。
