SHANGHAI, China, April 21, 2023 (GLOBE NEWSWIRE) — Shanghai Junshi Biosciences Co., Ltd (\u201cJunshi Biosciences\u201d, HKEX: 1877; SSE: 688180), a leading innovation-driven biopharmaceutical company dedicated to the discovery, development, and commercialization of novel therapies, today announced that positive interim event-free survival (EFS) results from the Neotorch study were presented at the ASCO April Plenary Series.<\/p>\n\n\n\n
Neotorch is the world\u2019s first phase 3 registered study demonstrating that perioperative treatment with anti-PD-1 monoclonal antibody significantly extends EFS of patients with resectable non-small cell lung cancer (NSCLC). It aims to evaluate the efficacy and safety of perioperative toripalimab, Junshi Biosciences\u2019 anti-PD-1 monoclonal antibody, in combination with chemotherapy, followed by toripalimab maintenance versus perioperative chemotherapy alone in resectable stage II\/III NSCLC.<\/p>\n\n\n\n
Among 404 stage lll NSCLC patients, the interim EFS analysis after a median follow-up of 18.25 months (cut-off date: Nov 30, 2022) revealed a significant EFS improvement in the toripalimab arm (HR = 0.40 [95% Cl, 0.277-0.565]; two-sided P < 0.0001). The median EFS was not reached in the toripalimab arm while it was 15.1 months in the placebo arm. Toripalimab demonstrated a consistent favorable effect on EFS in all subgroups, regardless of PD-L1 expression status.<\/p>\n\n\n\n
In the toripalimab arm, the major pathological response (MPR) and pathologic complete response (pCR) rates per blinded independent pathologic review (BIPR) of the study were also higher compared to the placebo arm, with rates of 48.5% vs. 8.4% (P<0.0001) and 24.8% vs. 1.0% (P<0.0001), respectively.<\/p>\n\n\n\n
Similarly, the overall survival (OS) results showed a trend favoring toripalimab. The median OS was not reached in the toripalimab arm, while it was 30.4 months in the placebo arm (HR=0.62). OS will be formally tested at the final analysis.<\/p>\n\n\n\n
In addition, after neoadjuvant therapy, more patients from the toripalimab arm underwent surgery compared to the placebo arm (82.2% vs. 73.3%), 95.8% and 92.6% of the patients underwent surgery and achieved R0 resection, respectively. The treatment was well-tolerated, with no new safety signals identified.<\/p>\n\n\n\n
Based on the Neotorch study, the National Medical Products Administration of China (NMPA) has accepted the supplemental new drug application (sNDA) for toripalimab in combination with chemotherapy as perioperative treatment and toripalimab monotherapy as maintenance therapy after adjuvant therapy for the treatment of resectable stage III NSCLC.<\/p>\n\n\n\n
\u201cThe Neotorch study has pioneered the world\u2019s first \u20183+1+13\u2019 perioperative treatment model for NSCLC, which incorporates immunotherapy into both preoperative neoadjuvant and postoperative adjuvant treatments,\u201d said Neotorch\u2019s Principal Investigator, Professor Shun LU from the Shanghai Chest Hospital. \u201cThe study results show that the addition of toripalimab to chemotherapy provided a superior EFS in stage III NSCLC patients than chemotherapy alone, while maintaining a manageable safety profile. We are hopeful that our innovative solution will further improve the effectiveness and assessibility of lung cancer treatments and medications and ignite a new torch of hope for patients!\u201d<\/p>\n\n\n\n
Dr. Jianjun ZOU, President of Global Research and Development at Junshi Biosciences, \u201cLung cancer has the highest mortality rate of all malignant cancers worldwide. Even with radical surgery in the earlier stages, some patients still experience recurrence or death. Today, immunotherapy has become standard of care for various late-stage cancers, and the exploration of its potential use as early-stage treatment is showing promising results. The Neotorch study has strengthened our resolve to find a cure for more cancer patients. The NMPA is currently reviewing our sNDA for the new indication based on the Neotorch data, and we are excited to work together to benefit early-stage lung cancer patients with this innovative therapy!\u201d<\/p>\n\n\n\n\n\n
About the Neotorch Study<\/strong><\/p>\n\n\n\n The Neotorch Study (NCT04158440) is a randomized, double-blind, placebo-controlled, Phase III trial evaluating the efficacy and safety of perioperative toripalimab plus chemotherapy, followed by toripalimab maintenance versus chemotherapy in resectable stage II\/III NSCLC. Patients with stage II\/III resectable NSCLC and without EGFR\/ALK alterations for non-squamous NSCLC were randomized 1:1 to receive 240 mg toripalimab or placebo, combined with chemotherapy Q3W for 3 cycles before surgery and one cycle after surgery, followed by toripalimab or placebo monotherapy Q3W for 13 cycles. The chemotherapy backbones varied depending on the histology of the cancer, with paclitaxel or docetaxel plus platinum for squamous cell carcinoma, and pemetrexed plus platinum for non-squamous cell carcinoma. Stratification variables for randomization included disease stage, histopathologic subtype, PD-L1 expression and surgical procedure. Primary endpoints were EFS as assessed by investigator and MPR rate as assessed by BIPR in the stage III and the ITT populations. Secondary endpoints included OS, pCR rate, EFS as assessed by independent review committee (IRC), and safety.<\/p>\n\n\n\n <\/p>\n\n\n\n About Toripalimab<\/strong><\/p>\n\n\n\n Toripalimab is an anti-PD-1 monoclonal antibody developed for its ability to block PD-1 interactions with its ligands, PD-L1 and PD-L2, and for enhanced receptor internalization (endocytosis function). Blocking PD-1 interactions with PD-L1 and PD-L2 promotes the immune system\u2019s ability to attack and kill tumor cells.<\/p>\n\n\n\n More than forty company-sponsored toripalimab clinical studies covering more than fifteen indications have been conducted globally by Junshi Biosciences, including in China, the United States, Southeast Asia, and European countries. Ongoing or completed pivotal clinical trials evaluating the safety and efficacy of toripalimab cover a broad range of tumor types including cancers of the lung, nasopharynx, esophagus, stomach, bladder, breast, liver, kidney and skin.<\/p>\n\n\n\n In China, toripalimab was the first domestic anti-PD-1 monoclonal antibody approved for marketing (approved in China as TUOYI\u00ae). Currently, there are six approved indications for toripalimab in China:<\/p>\n\n\n\n <\/p>\n\n\n\n The first three indications have been included in the National Reimbursement Drug List (NRDL) (2022 Edition). Toripalimab is the only anti-PD-1 monoclonal antibody included in the NRDL for treatment of melanoma.<\/p>\n\n\n\n In the United States, the Biologics License Application (BLA) for toripalimab in combination with gemcitabine\/cisplatin, for the first-line treatment of patients with advanced recurrent or metastatic NPC and toripalimab monotherapy for the second-line or later treatment of recurrent or metastatic NPC after platinum-containing chemotherapy is under review by the U.S. Food and Drug Administration (FDA). The FDA has granted Breakthrough Therapy designations for toripalimab in combination with chemotherapy for the first-line treatment of recurrent or metastatic NPC as well as for toripalimab monotherapy in the second or third-line treatment of recurrent or metastatic NPC. Additionally, the FDA has granted Fast Track designation for toripalimab for the treatment of mucosal melanoma and Orphan Drug designations for the treatment of esophageal cancer, NPC, mucosal melanoma, soft tissue sarcoma, and small cell lung cancer (SCLC).<\/p>\n\n\n\n In Europe, marketing authorization applications (MAA) were accepted by the European Medicines Agency (EMA) and the United Kingdom\u2019s Medicines and Healthcare products Regulatory Agency (MHRA) for 1) toripalimab combined with cisplatin and gemcitabine for the first-line treatment of patients with locally recurrent or metastatic NPC and 2) toripalimab combined with paclitaxel and cisplatin for the first-line treatment of patients with unresectable locally advanced\/recurrent or metastatic ESCC, in December 2022 and February 2023.<\/p>\n\n\n","protected":false},"excerpt":{"rendered":" SHANGHAI, China, April 21, 2023 (GLOBE NEWSWIRE) — Shanghai Junshi Biosciences Co., Ltd (\u201cJunshi Biosciences\u201d, HKEX: 1877; SSE: 688180), a leading innovation-driven biopharmaceutical company dedicated to the discovery, development, and commercialization of novel therapies, today announced that positive interim event-free survival (EFS) results from the Neotorch study were presented at the ASCO April Plenary Series.<\/p>\n","protected":false},"author":3,"featured_media":2154,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[22],"tags":[],"class_list":["post-2157","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized"],"yoast_head":"\n\n
