Working with patients and their providers, this trial will be fully enrolled with patients who are receiving commercial Signatera testing as part of their routine standard of care.. 在完成确定性治疗后,使用Natera的Signatera™检测,那些分子残留病(MRD)呈阳性且无影像学疾病证据的结直肠癌(CRC)患者将有资格入组STELLAR-316试验。通过与患者及其医疗服务提供者合作,该试验将完全招募那些作为常规护理标准的一部分而接受商业Signatera检测的患者。The primary endpoint of STELLAR-316 is disease-free survival. Signatera will also be used for longitudinal monitoring of circulating tumor DNA clearance, one of the secondary endpoints of the trial. STELLAR-316 的主要终点是无病生存期。Signatera 还将用于纵向监测循环肿瘤 DNA 清除情况,这是该试验的次要终点之一。Exelixis 埃克塞利西斯expects to initiate STELLAR-316 in mid-2026. 预计将在2026年年中启动STELLAR-316。CRC is the third most common cancer and the second leading cause of cancer-related deaths in the CRC 是第三大常见癌症,也是癌症相关死亡的第二大原因。U.S. 美国1 1Of the approximately 89,000 stage II/III colorectal cancer cases projected for 2035, 在预计2035年发生的约89,000例II/III期结直肠癌病例中,2 2about 20% of these patients are expected to remain MRD-positive following definitive therapy. 大约20%的患者在确定性治疗后预计仍为MRD阳性。3 3Patients with stage II/III CRC who are MRD-positive have been shown to experience worse outcomes in multiple clinical studies 在多项临床研究中,显示II/III期结直肠癌患者如果微小残留病(MRD)呈阳性,其预后较差 3,4,5 3,4,5and there are no established or approved therapies for this specific patient population in the 并且对于这一特定患者群体,没有已建立或批准的疗法在U.S. 美国“Patients with colorectal cancer who are MRD-positive following definitive therapy face a high risk of recurrence, underscoring the urgent need for new treatment options that can help prevent clinical metastatic progression,” said “在接受确定性治疗后MRD阳性的结直肠癌患者面临很高的复发风险,这凸显了对能够帮助防止临床转移进展的新治疗方案的迫切需求,”Dana T. Aftab 达纳·T·阿夫塔卜, Ph.D., Executive Vice President, ,博士,执行副总裁,Research and Development 研究与开发, ,Exelixis 埃克塞利西斯. “STELLAR-316 is our second pivotal trial of zanzalintinib in patients with CRC and represents our continued commitment to addressing unmet needs in this patient population by conducting rigorous trials with the potential to improve standards of care. We are excited to collaborate with Natera on STELLAR-316, which, if successful, could make zanzalintinib the first MRD-guided treatment for these patients.”. “STELLAR-316 是我们在结直肠癌患者中进行的第二项关键性赞扎林替尼试验,代表了我们通过开展具有提高护理标准潜力的严格试验来满足这一患者群体未满足需求的持续承诺。我们很高兴与 Natera 在 STELLAR-316 上合作,如果成功,这可能使赞扎林替尼成为这些患者的首个微小残留病灶(MRD)指导治疗。”“Exelixis and Natera’s collaboration on STELLAR-316 underscores both companies’ commitment to advancing new approaches to treat CRC,” said “Exelixis和Natera在STELLAR-316上的合作强调了两家公司致力于推进治疗结直肠癌的新方法,”John Simmons 约翰·西蒙斯, Ph.D., Global Vice President, Biopharma, Natera. “Leveraging Signatera to inform trial enrollment will help to identify high-risk patients earlier, enabling intervention when disease burden is lower – and importantly, with the potential to improve clinical outcomes.” 博士,Natera全球副总裁,生物制药部。“利用Signatera指导试验入组将有助于更早识别高风险患者,在疾病负担较低时进行干预——重要的是,有可能改善临床结果。”*Colon: adjuvant chemotherapy, rectal: total neoadjuvant therapy *结肠:辅助化疗,直肠:全程新辅助治疗About Zanzalintinib 关于赞扎林替尼Zanzalintinib is a novel oral kinase inhibitor that inhibits the activity of the TAM kinases (TYRO3, AXL, MER), MET and VEGF receptors. These kinases play important roles in oncogenic processes including tumor cell proliferation, metastasis, angiogenesis, drug resistance and evasion of antitumor immunity. Zanzalintinib 是一种新型的口服激酶抑制剂,可抑制 TAM 激酶(TYRO3、AXL、MER)、MET 和 VEGF 受体的活性。这些激酶在肿瘤发生过程中发挥重要作用,包括肿瘤细胞增殖、转移、血管生成、耐药性以及逃避免疫抗肿瘤免疫。With zanzalintinib, . 使用赞扎林替尼,。Exelixis 埃克塞利西斯sought to build upon its extensive experience with the target profile of cabozantinib, the company’s flagship medicine, while improving key characteristics, including pharmacokinetic half-life. Zanzalintinib is currently being developed for the treatment of advanced solid tumors, including colorectal cancer, kidney cancer and neuroendocrine tumors.. 该公司在开发其旗舰药物卡博替尼的过程中积累了丰富的经验,希望在此基础上改进关键特性,包括药代动力学半衰期。 Zanzalintinib目前正在被开发用于治疗晚期实体瘤,包括结直肠癌、肾癌和神经内分泌肿瘤。Exelixis 埃克塞利西斯recently confirmed it has submitted a New Drug Application to the 最近确认已提交新药申请至U.S. Food & Drug Administration 美国食品药品监督管理局for zanzalintinib for the treatment of patients with previously treated metastatic colorectal cancer, when used in combination with atezolizumab (Tecentriq 用于治疗先前接受过治疗的转移性结直肠癌患者时,与阿特珠单抗(Tecentriq)联合使用的赞扎利替尼® ®). The regulatory filing was based on positive results from the phase 3 STELLAR-303 pivotal trial, which met one of its dual primary endpoints, with the combination of zanzalintinib and atezolizumab demonstrating a statistically significant reduction in the risk of death versus regorafenib in the intention-to-treat population at the final analysis. )。该监管文件基于 3 期 STELLAR-303 关键试验的积极结果,该试验达到了其双重主要终点之一,最终分析显示,在意向治疗人群中,zanzalintinib 与 atezolizumab 的联合疗法相较于 regorafenib 在降低死亡风险方面具有统计学上的显著优势。An overall survival (OS) benefit with the combination was consistently observed across pre-specified subgroups, including geographic region, RAS status, liver involvement and prior anti-VEGF therapy. Data pertaining to the other dual primary endpoint, . 在预先指定的各亚组中,包括地理区域、RAS状态、肝脏受累情况以及之前的抗VEGF治疗,均一致观察到联合治疗带来的总生存期(OS)益处。关于另一个双重主要终点的数据,。OS in 操作系统在patients without liver metastases (non-liver metastases or NLM), were immature at the data cutoff. A prespecified interim analysis showed a trend in OS favoring the combination. The trial will proceed to the planned final analysis for this endpoint, which is expected in mid-2026, based on current event rates.. 截至数据截止时,未出现肝转移的患者(非肝转移或NLM)数据尚不成熟。预先设定的中期分析显示,总生存期(OS)有倾向于支持联合治疗的趋势。基于当前的事件发生率,试验将继续进行至计划中的最终分析,预计将在2026年年中完成。Zanzalintinib is an investigational agent that is not approved for any use and is the subject of ongoing clinical trials. Zanzalintinib 是一种研究性药物,尚未获准用于任何用途,并且正在进行临床试验。About CRC 关于CRCCRC is the third most common cancer and the second leading cause of cancer-related deaths in the CRC 是第三大常见癌症,也是癌症相关死亡的第二大原因。U.S. 美国1 1Approximately 154,000 new cases will be diagnosed in the 大约会有154,000个新病例被诊断出U.S. 美国with around 53,000 expected deaths from the disease in 2025. 预计到 2025 年,约有 53,000 人死于该疾病。1 1CRC is most frequently diagnosed among people aged 65-74 and is more common in men and in people of non-Hispanic American Indian/Alaska Native descent. CRC 最常在 65-74 岁的人群中被诊断出来,男性以及非西班牙裔的美洲印第安人/阿拉斯加原住民后裔中更为常见。6 6Nearly a quarter of CRC cases are diagnosed at the metastatic stage, at which point the five-year survival rate is just 16.2%. 将近四分之一的结直肠癌病例在转移阶段被诊断出来,此时的五年生存率仅为16.2%。6 6The liver is the most common site for CRC metastasis. Liver metastases significantly impact survival, with a median five-year survival rate of less than 14% when treated with palliative chemotherapy. 肝脏是结直肠癌转移最常见的部位。肝转移显著影响生存率,仅接受姑息性化疗的患者中位五年生存率低于14%。7 7About 关于Exelixis 埃克塞利西斯Exelixis 埃克塞利西斯is a globally ambitious oncology company innovating next-generation medicines and regimens at the forefront of cancer care.
