默克雪兰诺公司今天宣布，来自中国的一项关键的III期研究显示：西妥昔单抗联合FOLFOX在一线治疗RAS野生型转移性结直肠癌中显著延长病人无进展生存期（PFS），达到研究主要终点。研究显示：西妥昔单抗可以延长RAS野生型的mCRC患者的PFS，安全性是可管理的，和其他关键试验中观察到的类似，没有特别的的安全性问题出现。完整的研究成果将提交给即将举行的国际学术会议进行公开报道。
该研究的主要研究者，南京八一医院的秦叔逵教授指出：“我们很高兴地看到TAILOR研究结果支持爱必妥联合化疗成为转移性结直肠癌患者在中国新的一线治疗方案。这也是令人欣慰的结果，和之前的研究结果相类似，TAILOR研究支持一线爱必妥联合FOLFOX的方案。” 无论是NCCN指南（美国）还是ESMO临床指南都推荐用西妥昔单抗加FOLFOX或FOLFIRI一线治疗患者的RAS野生型转移性结直肠癌。
西妥昔单抗已获得上市许可在全球90多个国家。在欧洲，西妥昔单抗被表示为第一线治疗的患者与RAS野生型的转移性结直肠癌，与含奥沙利铂治疗方案FOLFOX方案一起在治疗初治患者或连同含伊立替康（例如FOLFIRI）。7超过442000例方案与转移性结直肠癌已与西妥昔单抗治疗。
关于TAILOR研究
TAILOR研究是一项III期，开放标签，随机，对照，多中心试验，旨在比较西妥昔单抗联合FOLFOX-4对比比较与FOLFOX-4在一线治疗中国RAS野生型转移性结直肠癌患者研究。所有随机受试者按计划接受相应治疗，直到疾病进展（PD）或不能接受的毒性的发生。该研究纳入397例RAS野生型转移性结直肠癌。试验的主要终点是无进展生存期（PFS）。次要终点包括：总生存期（OS），最佳的整体反应速度（ORR），及治疗失败时间和肝转移率。

Phase III TAILOR Landmark Study Demonstrates Significant Benefits of Erbitux in Combination with FOLFOX Over FOLFOX Alone
Chinese pivotal Phase III study meets its primary endpoint of increased progression-free survival in first-line treatment of patients with RAS wild-type metastatic colorectal cancer
Merck will work with relevant authorities to make Erbitux available for patients in China as a first-line treatment as soon as possible
This marks a major milestone of Merck's oncology strategy including expansion in growth markets
Merck, a leading science and technology company, today announced that the pivotal Chinese Phase III TAILOR study met its primary endpoint of significantly increasing progression-free survival (PFS) in patients with RAS wild-type metastatic colorectal cancer (mCRC) treated with Erbitux® (cetuximab) plus FOLFOX chemotherapy, compared with FOLFOX alone.
"We are thrilled with the TAILOR results that bring a major contribution to the available scientific evidence of Erbitux's efficacy in combination with FOLFOX as a standard first-line treatment for patients with RAS wild-type metastatic colorectal cancer. This marks a significant step in the execution of our strategy in oncology, notably the expansion in growth markets like China," said Luciano Rossetti, Head of Global Research and Development of Merck's biopharma business. "These impressive results reinforce the value and imperative of RAS biomarker testing in clinical practice, so as to provide patients with the right targeted therapy. These results also underscore why we continue to devote our efforts towards both improving testing and ensuring access to Erbitux worldwide."1-4
The clinical benefit that Erbitux offers to RAS wild-type mCRC patients is further strengthened by the secondary endpoint results, which support the superiority shown for PFS. The safety profile of Erbitux in the TAILOR clinical trial was manageable and similar to that observed in other pivotal trials, with no unexpected safety findings. The full study results will be submitted to upcoming international scientific meetings.
Both the National Comprehensive Cancer Network (U.S.) and the European Society for Medical Oncology clinical guidelines recommend first-line treatment with Erbitux plus FOLFOX or FOLFIRI for patients with RAS wild-type mCRC.5,6
"We are excited that the TAILOR study is positive and that Erbitux in combination with chemotherapy could become a new first-line treatment option for metastatic colorectal cancer patients in China, once approved," said Professor Shukui Qin from Nanjing Bayi Hospital, China, Coordinating Investigator in the TAILOR study. "It is also reassuring that the results reflect those previously observed, and support the indicated first-line use of Erbitux plus FOLFOX in many countries."
Erbitux has obtained marketing authorization in over 90 countries worldwide. In Europe, Erbitux is indicated as first-line therapy for patients with RAS wild-type mCRC tumors, together with the oxaliplatin-containing regimen FOLFOX in treatment-naïve patients or together with regimens containing irinotecan (e.g. FOLFIRI).7 More than 442,000 patients with mCRC have been treated with Erbitux.
About the TAILOR study
The TAILOR study is a Phase III, open-label, randomized, controlled, multicenter trial designed to compare Erbitux in combination with FOLFOX-4 versus FOLFOX-4 alone in the first-line treatment of Chinese patients with RAS wild-type mCRC. All randomized subjects were planned to receive treatment until the occurrence of progressive disease (PD) or unacceptable toxicity. The study enrolled 397 patients with RAS wild-type mCRC. The primary endpoint of the trial is progression-free survival. Secondary endpoints include: overall survival, best overall response rate, time to treatment failure and rate of curative surgery for liver metastases.
About mCRC
Approximately half of patients with mCRC have RAS wild-type tumors and half have RAS mutant tumors.8 Results from studies assessing RAS mutation status in patients with mCRC have shown that anti-epidermal growth factor receptor (EGFR) monoclonal antibody therapies, such as Erbitux® (cetuximab), can improve outcomes in patients with RAS wild-type mCRC.1-4 Colorectal cancer (CRC) is the third most common cancer worldwide, with an estimated incidence of more than 1.36 million new cases annually.9 An estimated 694,000 deaths from CRC occur worldwide every year, accounting for 8.5% of all cancer deaths and making it the fourth most common cause of death from cancer.9 Almost 55% of CRC cases are diagnosed in developed regions of the world, and incidence and mortality rates are substantially higher in men than in women.9
About Erbitux
Erbitux® is a highly active IgG1 monoclonal antibody targeting the epidermal growth factor receptor (EGFR). As a monoclonal antibody, the mode of action of Erbitux is distinct from standard non-selective chemotherapy treatments in that it specifically targets and binds to the EGFR. This binding inhibits the activation of the receptor and the subsequent signal-transduction pathway, which results in reducing both the invasion of normal tissues by tumor cells and the spread of tumors to new sites. It is also believed to inhibit the ability of tumor cells to repair the damage caused by chemotherapy and radiotherapy and to inhibit the formation of new blood vessels inside tumors, which appears to lead to an overall suppression of tumor growth.
The most commonly reported side effect with Erbitux is an acne-like skin rash that seems to be correlated with a good response to therapy. In approximately 5% of patients, hypersensitivity reactions may occur during treatment with Erbitux; about half of these reactions are severe.
Erbitux has already obtained market authorization in over 90 countries world-wide for the treatment of colorectal cancer and for the treatment of squamous cell carcinoma of the head and neck (SCCHN). Merck licensed the right to market Erbitux outside the US and Canada from ImClone LLC, a wholly-owned subsidiary of Eli Lilly and Company, in 1998. Merck has an ongoing commitment to the advancement of oncology treatment and is currently investigating novel therapies in highly targeted areas.
