SHANGHAI, Aug. 26, 2024 /PRNewswire/ -- Mabwell (688062.SH), an innovative biopharmaceutical company with entire industry chain, announced that its submission to the Center for Drug Evaluation (CDE) of the National Medical Products Administration (NMPA) for "a randomized, controlled, open-label, multicenter Phase III clinical study of 9MW2821 in combination with Toripalimab versus standard chemotherapy in first-line locally advanced or metastatic urothelial cancer" has been approved. The corresponding Phase III clinical study has been initiated and is currently in the enrollment stage. As of the announcement, 9MW2821 has been approved for three pivotal clinical trials. 9MW2821 is a novel Nectin-4-targeting ADC independently developed by Mabwell, and it is the first of its kind in China to initiate clinical trials on the same target, with more than 400 subjects enrolled in the clinical studies for multiple indications. The results of existing clinical studies have demonstrated outstanding therapeutic efficacy and safety profile. The pivotal Phase III clinical study, "an open-label, randomized Phase 3 study to evaluate 9MW2821 vs investigator's choice of chemotherapy in subjects with locally advanced or metastatic urothelial cancer who have previously received PD-(L)1 inhibitor and platinum-containing chemotherapy", is currently in the enrollment stage. About Urothelial Carcinoma Bladder cancer, a form of urothelial carcinoma, stands out among its various subtypes for its significant impact on public health. The American Society of Clinical Oncology reports that bladder cancer is the ninth most common malignant tumor in incidence and ranks thirteenth in mortality among all malignant tumors. According to The Global Cancer Statistics published by the International Agency for Research on Cancer (IARC) in 2022, there were approximately 614,000 new cases and 220,000 deaths from bladder cancer worldwide. The Disease Burden of Malignant Tumors in China 2022, released by the National Cancer Center in February 2024, reported 92,900 new cases and 41,400 deaths from bladder cancer in China, placing it eleventh and thirteenth globally in terms of new incidences and mortality, respectively. As a prevalent cancer in China, urothelial carcinoma is characterized by a propensity for metastasis, a high recurrence rate, and a short survival time in its advanced stages. It represents a significant disease burden and poses a serious threat to the survival and quality of life of those affected. About 9MW2821 9MW2821 is a site-specific conjugated novel Nectin-4 targeting ADC developed by Mabwell using ADC platform, and the first drug candidate to enter clinical study among the Nectin-4-targeting ADCs developed by Chinese companies. As the first therapeutic drug candidate targeting Nectin-4 in the world to reveal clinical efficacy data in cervical cancer (CC), esophageal cancer (EC) and breast cancer, 9MW2821 has been granted Fast Track Designation by FDA in 2024 for the treatment of advanced, recurrent, or metastatic esophageal squamous cell carcinoma (ESCC), recurrent or metastatic CC progressed on or following prior treatment with a platinum-based chemotherapy regimen, and locally advanced or metastatic Nectin-4 positive triple-negative breast cancer (TNBC); 9MW2821 has also been granted Orphan Drug Designation by FDA for the treatment of EC, and Breakthrough Therapy Designation by CDE of NMPA, for the treatment of locally advanced or metastatic urothelial carcinoma that has failed previous platinum-based chemotherapy and PD-(L)1 inhibitor therapy. 9MW2821 achieves site-specific modification of antibody through proprietary conjugation technology linkers and optimized ADC conjugation process. After injection, 9MW2821 can specifically bind to Nectin-4 on the cell membrane surface, be internalized and release cytotoxic drug, and induce the apoptosis of tumor cells.

SHANGHAI, Aug. 23, 2024 /PRNewswire/ -- Mabwell (688062.SH), an innovative biopharmaceutical company with entire industry chain, announced that its submission to the Center for Drug Evaluation (CDE) of the National Medical Products Administration (NMPA) for the "A Randomized, Open-label, Phase III Study to Evaluate 9MW2821 vs Investigator's Choice of Chemotherapy in Subjects with Recurrent or Metastatic Cervical Cancer Who Progressed on or after Platinum-based Chemotherapy" has been approved. The company will initiate the Phase III clinical study to assess the efficacy and safety of 9MW2821 in patients with recurrent or metastatic cervical cancer (CC) that has progressed on or after platinum-based chemotherapy. 9MW2821, a novel Nectin-4 targeting ADC developed by Mabwell, is the first drug candidate to enter clinical study among the Nectin-4-targeting ADCs developed by Chinese companies. It's also the first Nectin-4-targeting ADC to enter phase III clinical study for the treatment of CC worldwide. Multiple clinical studies have been conducted for urothelium carcinoma, cervical cancer, esophageal cancer, and breast cancer, and more than 400 subjects have been enrolled. The results of the existing clinical studies have demonstrated outstanding therapeutic efficacy and safety. Treatment options and outcomes for patients with recurrent or metastatic cervical cancer remain limited. In the cervical cancer expansion cohort of the phase I/II study, the detection rate of Nectin-4 expression was 91.87%, and the detection rate of Nectin-4 IHC 3+ was 73.98%. 53 CC patients received at least one dose of 9MW2821 and were evaluable for efficacy assessment. All of the patients had received doublet platinum-containing chemotherapy, 51% patients had received bevacizumab, and 58% patients had received immune checkpoint inhibitor. ORR and DCR in 53 CC patients were 35.8% and 81.1%, respectively. The median progression-free survival (mPFS) and duration of response (DOR) was 3.9 months and 7.2 months, respectively. Median overall survival (OS) was not reached yet and 12-months OS rate was 74.6%. Among patients with Nectin-4 IHC 3+, the ORR was 43.6%. The results of the above studies indicate that 9MW2821 has a positive therapeutic effect in patients with cervical cancer. The company is in the process of scientifically evaluating and advancing the conduct of clinical studies on first-line combination therapies. About Cervical Cancer Cervical cancer is the 4th most common neoplasm and the 4th leading cause of cancer death in females worldwide (excerpted from "Worldwide trends in cervical cancer incidence and mortality, with predictions for the next 15 years, Cancer 2021"). According to the "World Cancer Report 2020" released by the International Agency for Research on Cancer (IARC), there were 600 thousand new cases of cervical cancer worldwide in 2020 and up to 340 thousand deaths caused by cervical cancer. In February 2024, the National Cancer Center published the Cancer Burden Data in China in 2022 on Journal of the National Cancer Center (JNCC), showing that there were 150.7 thousand new cases of cervical cancer and 55.7 thousand deaths in China, ranking 8th and 9th respectively in terms of new cases and number of deaths. Compared with the 119 thousand new cases and 37 thousand deaths released in February 2022 for the same period in 2016, significant increases are observed. About 9MW2821 9MW2821 is the first site-specific conjugated novel Nectin-4 targeting ADC developed by Mabwell using ADC platform, and is the first drug candidate to enter clinical study among the Nectin-4-targeting ADCs developed by Chinese companies, and also the first therapeutic drug candidate targeting Nectin-4 in the world to reveal clinical efficacy data of cervical cancer (CC), esophageal cancer (EC) and breast cancer.
