Loxo Oncology首席执行官Josh Bilenker博士表示：“我们很高兴larotrectinib的NDA已被FDA接受并获得优先审评资格。Larotrectinib标志着治疗癌症方面的一个重要转变，癌症治疗将基于肿瘤的遗传学特征，而不再是癌症在体内的起源部位。”
如果获批，Larotrectinib将成为首款不区分肿瘤来源的小分子抗癌药物，具有划时代意义。2017年5月23日，美国FDA传来一条重量级消息——由默沙东（MSD）带来的KEYTRUDA（pembrolizumab）获批治疗带有微卫星不稳定性高（microsatellite instability-high，MSI-H）或错配修复缺陷（mismatch repair deficient，dMMR）的实体瘤患者，他们的病情在先前的治疗后都出现了进展。值得一提的是，这是美国FDA批准的首款不依照肿瘤来源，而是依照生物标志物进行区分的抗肿瘤疗法，具有里程碑式的意义。

(LOXO), a biopharmaceutical company innovating the development of highly selective medicines for patients with genetically defined cancers, today announced that the U.S. Food and Drug Administration (FDA) has accepted the company’s New Drug Application (NDA) and granted Priority Review for larotrectinib for the treatment of adult and pediatric patients with locally advanced or metastatic solid tumors harboring an NTRK gene fusion. The FDA has set a target action date of November 26, 2018, under the Prescription Drug User Fee Act (PDUFA).
“We are excited the larotrectinib NDA has been accepted by FDA and granted Priority Review status,” said Josh Bilenker, M.D., chief executive officer of Loxo Oncology. “Larotrectinib marks an important shift towards treating cancer based on the tumor’s genetics rather than its site of origin in the body.”
The FDA grants Priority Review for the applications of medicines that, if approved, would provide significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions when compared to standard applications. Larotrectinib has also been granted Breakthrough Therapy Designation, Rare Pediatric Disease Designation and Orphan Drug Designation by the FDA.
Loxo Oncology and Bayer are engaged in a collaboration for the development and commercialization of larotrectinib. Bayer plans to submit a Marketing Authorization Application (MAA) in the European Union in 2018.
About Larotrectinib (LOXO-101)
Larotrectinib is an oral and highly selective investigational tropomyosin receptor kinase (TRK) inhibitor in clinical development for the treatment of patients with cancers that harbor a neurotrophic tyrosine receptor kinase (NTRK) gene fusion. Growing research suggests that the NTRK genes, which encode for TRKs, can become abnormally fused to other genes, resulting in growth signals that can lead to cancer in many sites of the body. In clinical trials, larotrectinib demonstrated anti-tumor activity in patients with tumors harboring NTRK gene fusions, regardless of patient age or tumor type. In an analysis of 55 RECIST-evaluable adult and pediatric patients with NTRK gene fusions, larotrectinib demonstrated a 75 percent centrally-assessed confirmed overall response rate (ORR) and an 80 percent investigator-assessed confirmed ORR, across many different types of solid tumors. The majority of all adverse events were grade 1 or 2.
Larotrectinib has been granted Priority Review, Breakthrough Therapy Designation, Rare Pediatric Disease Designation and Orphan Drug Designation by the U.S. FDA.
In November 2017, Loxo Oncology and Bayer entered into an exclusive global collaboration for the development and commercialization of larotrectinib and LOXO-195, a next-generation TRK inhibitor. Bayer and Loxo Oncology will jointly develop the two products with Loxo Oncology leading the ongoing clinical studies as well as the filing in the U.S., and Bayer leading ex-U.S. regulatory activities and worldwide commercial activities. In the U.S., Loxo Oncology and Bayer will co-promote the products.

About TRK Fusion Cancer
TRK fusion cancer occurs when a neurotrophic tyrosine receptor kinase (NTRK) gene fuses with another unrelated gene, producing an altered tropomyosin receptor kinase (TRK) protein. The altered protein, or TRK fusion protein, is constantly active, triggering a permanent signal cascade. These proteins become the primary driver of the spread and growth of tumors in patients with TRK fusion cancer. TRK fusion cancer is not limited to certain types of cells or tissues and can occur in any part of the body. NTRK gene fusions occur in various adult and pediatric solid tumors with varying prevalence, including appendiceal cancer, breast cancer, cholangiocarcinoma, colorectal cancer, GIST, infantile fibrosarcoma, lung cancer, mammary analogue secretory carcinoma of the salivary gland, melanoma, pancreatic cancer, thyroid cancer, and various sarcomas. It may affect greater than 60 percent of both adult and pediatric patients with certain rare tumor types, such as secretory breast, secretory salivary gland and infantile fibrosarcoma. Only sensitive and specific tests can reliably detect TRK fusion cancer. Next-generation sequencing (NGS) can provide a comprehensive view of genomic alterations across a large number of genes. Fluorescence in situ hybridization (FISH) can also be used to test for TRK fusion cancer, and immunohistochemistry (IHC) can be used to detect the presence of TRK protein
