Pivotal Phase 3 VERITAC-2 clinical trial results presented at ASCO demonstrate 2.9-month improvement in median progression-free survival when compared to fulvestrant in second line-plus patients with an estrogen receptor 1 mutation Vepdegestrant was generally well tolerated, with few discontinuations and low rates of gastrointestinal-related adverse events Vepdegestrant is the first and only PROteolysis TArgeting Chimera (PROTAC) evaluated in a Phase 3 clinical trial and the first to show benefit in patients with breast cancer Data to be featured in a late-breaking oral presentation at ASCO and simultaneously published in the New England Journal of Medicine Arvinas will host a conference call to discuss these results on Monday, June 2, at 8:00 a.m. ET NEW HAVEN, Conn. and NEW YORK, May 31, 2025 – Arvinas, Inc. (Nasdaq: ARVN) and Pfizer Inc. (NYSE: PFE) today announced detailed results from the Phase 3 VERITAC-2 clinical trial (NCT05654623) evaluating vepdegestrant monotherapy versus fulvestrant in adults with estrogen receptor-positive, human epidermal growth factor receptor 2-negative (ER+/HER2-) advanced or metastatic breast cancer (MBC) whose disease progressed following prior treatment with cyclin-dependent kinase (CDK) 4/6 inhibitors and endocrine therapy. These data, which were highlighted in the American Society of Clinical Oncology (ASCO®) press briefing and selected for Best of ASCO, will be presented today in a late-breaking oral presentation (Abstract LBA1000) and have been simultaneously published in the New England Journal of Medicine. In the trial, vepdegestrant demonstrated a statistically significant and clinically meaningful improvement in progression-free survival (PFS) among patients with an estrogen receptor 1 (ESR1) mutation, reducing the risk of disease progression or death by 43% compared to fulvestrant [Hazard Ratio (HR)=0.57 (95% CI 0.42–0.77); 2-sided P<0.001]. The median PFS, as assessed by blinded independent central review (BICR), was 5.0 months with vepdegestrant versus 2.1 months with fulvestrant. Investigator-assessed PFS was consistent with the BICR-assessed PFS. In patients with ESR1 mutations, vepdegestrant demonstrated a consistent PFS benefit over fulvestrant across all pre-specified subgroups. The trial did not reach statistical significance in improvement in PFS in the intent-to-treat (ITT) population, with a median PFS of 3.7 months for vepdegestrant versus 3.6 for fulvestrant [HR=0.83 (95% CI 0.68–1.02); 2-sided P=0.07]. “Many patients with ER+/HER2- metastatic breast cancer who progress on endocrine therapy have tumors with ESR1 mutations, which drive resistance to standard treatments,” said Erika P. Hamilton, M.D., Director, Breast Cancer Research, Sarah Cannon Research Institute, and a principal investigator of the VERITAC-2 trial. “The VERITAC-2 results are promising and suggest that vepdegestrant could offer a much-needed treatment option for these patients, with a low incidence of burdensome GI effects that can meaningfully affect daily life.” Vepdegestrant was generally well tolerated in the trial, with a safety profile consistent with what has been observed in previous studies, and mostly low-grade treatment-emergent adverse events (TEAEs). Rates and severity of gastrointestinal adverse events were low with vepdegestrant (nausea, 13.5%; vomiting, 6.4%; diarrhea, 6.4%). Grade 4 TEAEs were reported in 5 patients (1.6%) in the vepdegestrant arm versus 9 patients (2.9%) in the fulvestrant arm. The three most common TEAEs observed with vepdegestrant were fatigue (26.6%), increased alanine transaminase (ALT) (14.4%) and increased aspartate aminotransferase (AST) (14.4%). TEAEs leading to treatment discontinuation occurred in 2.9% of patients taking vepdegestrant versus 0.7% of patients taking fulvestrant. “Based on these strong data from VERITAC-2, we believe that vepdegestrant has the potential to be a best-in-class monotherapy treatment for patients in the second-line ESR1-mutant setting,” said John Houston, Ph.D., Chairperson, Chief Executive Officer and President at Arvinas. “We are excited to engage with regulatory authorities on next steps to potentially bring vepdegestrant to healthcare providers and their patients as swiftly as possible.” Overall survival (OS), the key secondary endpoint in VERITAC-2, was immature at the time of the analysis, with less than a quarter of the required number of events having occurred. Additional secondary endpoints include clinical benefit rate (CBR) and objective response rate (ORR) and duration of response by BICR. In patients with an ESR1 mutation, CBR was 42.1% with vepdegestrant versus 20.2% with fulvestrant [odds ratio 2.88 (95% CI: 1.57–5.39); nominal P<0.001] and ORR was 18.6% with vepdegestrant versus 4.0% with fulvestrant [odds ratio 5.45 (95% CI: 1.69–22.73); nominal P=0.001]. The median duration of response was not reached. “Patients whose tumors harbor ESR1 mutations can face a poor prognosis, often experiencing rapid disease progression on endocrine therapy,” said Johanna Bendell, M.D., Chief Oncology Development Officer, Pfizer. “These results highlight the important role vepdegestrant may play in combating ESR1 mutation treatment resistance for these patients.” Approximately 2.3 million new breast cancer diagnoses were reported globally in 2022, and it is estimated there will be nearly 320,000 new diagnoses in the United States in 2025. ER+/HER2- breast cancer accounts for approximately 70% of all cases. Nearly 30% of women initially diagnosed with early-stage breast cancer will ultimately develop metastatic disease,1 with resistance to current standard-of-care treatments often emerging during first-line therapy, leading to disease progression. ESR1 mutations are a common cause of acquired resistance and are found in approximately 40% of patients in the second-line setting.2,3,4 Vepdegestrant, an investigational oral PROTAC ER degrader for ER+/HER2- breast cancer being jointly developed by Arvinas and Pfizer, is designed to harness the body’s natural protein disposal system to specifically target and degrade the ER. These detailed results follow the March 2025 announcement of the topline results from VERITAC-2. The companies plan to submit a New Drug Application (NDA) for vepdegestrant to the U.S. Food & Drug Administration (FDA) in the second half of 2025.

About the VERITAC-2 Clinical Trial The Phase 3 VERITAC-2 clinical trial (NCT05654623) is a global randomized trial evaluating the efficacy and safety of vepdegestrant (ARV-471) as a monotherapy compared to fulvestrant in patients with ER+/HER2- advanced or metastatic breast cancer. The trial enrolled 624 patients at sites in 26 countries who had previously received treatment with a CDK4/6 inhibitor plus endocrine therapy. Patients were randomized 1:1 to receive either vepdegestrant once daily, orally on a 28-day continuous dosing schedule, or fulvestrant, administered intramuscularly on Days 1 and 15 of Cycle 1 and then on Day 1 of each 28-day cycle starting from Day 1 of Cycle 2. In the trial, 43% of patients (n=270) had ESR1 mutations detected. The primary endpoint was progression-free survival (PFS) in the ESR1-mutation and intent-to-treat populations as determined by blinded independent central review. Overall survival is the key secondary endpoint. About Vepdegestrant Vepdegestrant is an investigational, orally bioavailable PROteolysis TArgeting Chimera (PROTAC) protein degrader designed to specifically target and degrade the estrogen receptor (ER) for the treatment of patients with ER-positive (ER+)/human epidermal growth factor receptor 2 (HER2)-negative (ER+/HER2-) breast cancer. Vepdegestrant is being developed as a potential monotherapy for ER+/HER2- advanced or metastatic breast cancer with estrogen receptor 1 (ESR1) mutations in the second line-plus setting. In July 2021, Arvinas announced a global collaboration with Pfizer for the co-development and co-commercialization of vepdegestrant; Arvinas and Pfizer will share worldwide development costs, commercialization expenses, and profits. The U.S. Food and Drug Administration (FDA) has granted vepdegestrant Fast Track designation as a monotherapy in the treatment of adults with ER+/HER2- advanced or metastatic breast cancer previously treated with endocrine-based therapy.

点击蓝字，关注我们编者按：CDK4/6抑制剂（CDK4/6i）做为HR+/HER2-晚期乳腺癌（HR+/HER2- MBC）中的标准治疗药物，为患者治疗带来了更多有效方案。探索更高效低毒的新型CDK4/6i，对提升患者长期生存质量至关重要。今日，NMPA正式批准原研进口的来罗西利用于HR+/HER2- MBC成人患者的一线（与芳香化酶抑制剂联用）及二线（与氟维司群联用）治疗，此举标志着我国HR+/HER2-乳腺癌治疗迈入新阶段。值此之际，肿瘤瞭望特邀LEONARDA-2首席研究者复旦大学附属肿瘤医院胡夕春教授，深度剖析来罗西利的循证医学证据与药物机制优势，共探其临床应用前景。01肿瘤瞭望：在LEONARDA-2研究中，来罗西利联合来曲唑方案针对HR+/HER2-局部晚期或转移性乳腺癌患者展现出了卓越的疗效。您能详细分享一下该研究的主要疗效数据吗？这些数据的公布对于中国HR+晚期乳腺癌患者的一线治疗有何重要意义？胡夕春教授：来罗西利是一种新型CDK4/6抑制剂，在临床中进行了一系列研究。第一个针对中国患者的III期临床研究是LEONARDA-1研究[1]，该研究纳入了既往接受内分泌治疗后疾病复发或进展的HR+/HER2-晚期或转移性乳腺癌患者，评估了来罗西利+氟维司群治疗的疗效和安全性。结果显示，相较于对照组（安慰剂+氟维司群），研究组（来罗西利+氟维司群）能够明显提高患者的治疗效果，延长患者的PFS[研究者评估的PFS：11.07个月vs 5.49个月，风险比（HR）0.451，95%CI: 0.311～0.656，P=0.000016）]。鉴于来罗西利在晚期二线治疗的中成功，我们发起了针对中国患者的多中心III期LEONARDA-2研究[2]，该研究入组了HR+/HER2-晚期或转移性乳腺癌患者，这些患者在晚期阶段既往未接受过系统治疗。将患者按1∶1的比例随机分配至来罗西利联合来曲唑组（研究组）或安慰剂联合来曲唑组（对照组）。主要研究终点是由研究者评估的PFS。次要终点包括由盲法独立中心审查（BICR）评估的PFS、客观缓解率（ORR）、总生存期（OS）和安全性等。结果显示，研究组无论在PFS方面，还是在有效率方面，都明显优于对照组。与对照组相比，研究组显著改善患者的PFS[中位数：未达到（NR） vs 16.56个月；HR：0.464，95% Cl: 0.293～0.733；P=0.0004]，疾病进展或死亡风险降低约54%。此外，研究者评估和独立评审委员会（IRC）评估的PFS都显示出一致获益。在ORR和CBR方面，来罗西利+来曲唑也显示出了较好的临床获益。结合来罗西利在晚期乳腺癌一线及二线治疗阶段的临床试验数据，我们观察到，该药物不仅在这两个治疗阶段均显著提升了治疗有效率，提高了患者的临床获益程度，更在延长患者PFS方面展现出了卓越效果。为中国晚期HR+/HER2-乳腺癌患者开辟了一条新的治疗路径，带来了新的治疗希望与选择。02肿瘤瞭望：来罗西利作为一种结构创新的新型CDK4/6抑制剂，其独特的分子结构在LEONARDA-2研究中发挥了哪些关键作用？这种结构创新如何提升了中国HR+晚期乳腺癌患者的疗效和安全性？胡夕春教授：当前，中国市场上已有哌柏西利、阿贝西利、瑞波西利及达尔西利这4款CDK4/6抑制剂获批上市。在新药研发领域，我们始终致力于探寻疗效更优、安全性更高的CDK4/6抑制剂，即所谓的“me better”乃至“me best”药物，而来罗西利的研发正是基于这一初衷，旨在为患者带来更为理想的治疗方案。来罗西利的分子结构中引入了三并环&螺环结构，这种结构创新提升了其对CDK4靶点的亲和力（高选择性），降低了与非靶标蛋白的结合概率，从而减少了脱靶效应。临床前动物研究提示，来罗西利具有高渗透性，且其在肿瘤组织的分布浓度远高于血浆浓度，在血浆浓度降到未检出水平时，肿瘤组织浓度仍较高[3]，表现出肿瘤组织高渗透，血液低蓄积的特性。所以我们同样能够观察到，其给患者带来的骨髓抑制相较于其他CDK4/6抑制剂更轻。基于来罗西利PK/PD特征，来罗西利具备“me better”的苗头。在LEONARDA-2研究中[2]，相较于对照组，研究组的PFS、ORR和CBR均有更多获益，其中HR为0.464（95% Cl: 0.293～0.733），在当前已上市CDK4/6i一线研究中HR值处于偏低水平，表明来罗西利的临床获益好[4-9]；且各亚组获益一致，其中内脏转移、多转移部位（≥3）亚组的HR值分别为0.420、0.399，均优于全人群，这也印证了来罗西利的高选择、高渗透的作用机制。在药物安全性方面，研究组的不良反应率较低，总体安全性较好。特别是4级中性粒细胞减少症的发生率较低（5.1%），胃肠道不良事件多为轻度，且无静脉血栓栓塞事件（VTE）发生；与对照组相比，来罗西利组不增加Q-T间期延长。在耐受性方面，因TEAEs导致停用来罗西利的情况罕见[1例患者（0.7%）]。综上，结构创新使得来罗西利在中国HR+晚期乳腺癌患者中能够更有效地抑制肿瘤生长，延长患者的PFS，并提高患者的生活质量。03肿瘤瞭望：随着来罗西利联合来曲唑方案在中国获批上市，您认为这一新方案将对HR+晚期乳腺癌患者的一线治疗产生哪些深远影响？您如何看待这一新方案在未来临床实践中的应用前景？胡夕春教授：HR+/HER2-乳腺癌约占所有乳腺癌的70%。尽管我国目前已有4种CDK4/6抑制剂可供患者选择，但这一患者群体仍存在未被满足的临床需求。例如，在使用CDK4/6抑制剂治疗时，患者可能面临中性粒细胞减少、静脉血栓、Q-T间期延长、肝毒性等不良反应，这些都是我们需要解决的问题。因此，临床上我们需要找到一种既有效、毒副反应又比较低的药物。而LEONARDA-2研究[2]和LEONARDA-1研究[1]的结果以及已报道的其他CDK4/6i相关研究显示[4-9]，来罗西利联合内分泌治疗在血液系统毒性、Q-T间期延长、静脉血栓等方面的安全性表现非常出色。在指南规范和共识中，无论对于晚期一线治疗还是二线治疗，CDK4/6抑制剂都是HR+/HER2-乳腺癌的标准治疗药物。来罗西利的获批上市，使我们的治疗选择更加丰富。来罗西利联合内分泌治疗作为更高效、安全的选择，为临床医生提供了更多方案。在考虑患者治疗方案时，来罗西利联合内分泌治疗是可以优先考虑的。当然，要真正确定哪一种CDK4/6抑制剂是“最优选择”（me best），我们需要发起头对头研究。如果目前没有这样的临床研究，我们也希望通过真实世界的数据来进一步证明来罗西利是一种高效、安全的CDK4/6抑制剂。参考文献：（滑动查看）1、Xu, Binghe et al. “Lerociclib plus fulvestrant in patients with HR+/HER2- locally advanced or metastatic breast cancer who have progressed on prior endocrine therapy: LEONARDA-1 a phase III randomized trial.” Nature communications vol. 16,1 716. 16 Jan. 2025, doi:10.1038/s41467-025-56096-22、Xichun Hu,et al.
