Squamous Cell Carcinoma

SHANGHAI, March 19, 2024 /PRNewswire/ -- Mabwell (688062.SH), an innovative-driven biopharmaceutical company with entire industry chain, presented the clinical study data of the 9MW2821 for patients with cervical cancer as focused plenary oral presentation at the Society of Gynecologic Oncology (SGO) annual meeting on March 16, 2024. The data showed good efficacy and safety of 9MW2821 in patients with cervical cancer, which is expected to bring new breakthroughs for the treatment of recurrent or metastatic cervical cancer, meeting a large number of unmet clinical needs. 9MW2821 is the first drug to report clinical data for the indication of cervical cancer among the drugs with the same target in the world. Report on Study Data of Nectin-4-Targeting Antibody-drug Conjugate ( ADC ) for the Treatment of Recurrent or Metastatic Cervical Cancer This phase I/II, multicenter, open-label, clinical study was led by Professor Zhang Jian of Fudan University Shanghai Cancer Center, and Professor Yang Huijuan of Fudan University Shanghai Cancer Center represented the study team to give an in-depth report at the meeting. The study results were highly recognized by experts on site. Further clinical study data are expected to provide more treatment options for patients with recurrent or metastatic cervical cancer. Clinical Findings The systemic treatment drug options and efficacy for recurrent or metastatic cervical cancer are relatively limited. The cervical cancer cohort in the phase I/II study of 9MW2821 enrolled patients with Nectin-4-positive recurrent or metastatic cervical cancer who had progressed on or after doublet platinum-containing chemotherapy with or without bevacizumab and received no more than two previous systemic regimens for recurrent or metastatic disease. Eligible patients received intravenous 9MW2821 1.25mg/kg on days 1, 8 and 15 of each 28-day cycle until confirmed disease progression, death, intolerable adverse effects or withdrawal from the study. As of September 25, 2023, in the cervical cancer expansion cohort of the study, the detection rate of Nectin-4 expression was 89.67%, and the rate of Nectin-4 IHC 3+ was 67.82%. A total of 40 patients were enrolled in the study, 57.5% of the patients had previously received platinum-based doublet chemotherapy combined with bevacizumab, and 60% of the patients had previously received platinum-based doublet chemotherapy and immune checkpoint inhibitor therapy. In terms of efficacy, the overall response rate (ORR) and disease control rate (DCR) of 37 patients evaluable for efficacy were 40.54% and 89.19%, respectively, with one complete response (2.70%) and 14 partial responses (37.84%). Median progression-free survival (PFS), overall survival (OS), and duration of response (DOR) were not reached yet. Among patients with Nectin-4 IHC 3+, the ORR and DCR of 26 patients evaluable for efficacy were 50.00% and 92.31%, respectively. Among patients on or after doublet platinum-containing chemotherapy, the ORR and DCR of 21 patients evaluable for efficacy were 38.10% and 85.71%, respectively. In terms of safety, treatment-related adverse events (TRAEs) occurred in 92.50% of participants. Grade3-4 TRAEs occurred in 70.00% of participants, with neutropenia (40.00%), rash (17.50%) and gamma-glutamyl transferase increased (12.50%) being the most frequently reported. Nodeaths related to treatment were reported. The above study results indicate that 9MW2821 has controllable safety and positive efficacy in patients with cervical cancer. About 9MW2821 9MW2821 is the first site-specific conjugated novel ADC targeting Nectin-4 developed by Mabwell using ADC platform and automated high-throughput hybridoma antibody molecular discovery platform, and is the first product to enter clinical study among the products with the same target developed by Chinese companies. Multiple clinical studies of 9MW2821 have been conducted in China to evaluate the safety, tolerability, pharmacokinetic characteristics, and efficacy of 9MW2821 in patients with various advanced solid tumors. The phase III clinical study of 9MW2821 monotherapy has officially been initiated in patients with locally advanced or metastatic urothelial carcinoma who have previously received platinum-based chemotherapy and PD-(L)1 inhibitor therapy. The phase I/II clinical study of 9MW2821 in combination with PD-1 inhibitors is also ongoing, with the first patient already enrolled. The phase II clinical study for the indication of esophageal carcinoma will continue enrollment and evaluation, and communication for the initiation of phase III clinical study will be expedited. 9MW2821 was granted Fast Track Designation (FTD) by the U.S. Food and Drug Administration (FDA) in February 2024 for the treatment of advanced, recurrent, or metastatic esophageal squamous cell carcinoma. Currently, 9MW2821 is the first therapeutic drug targeting Nectin-4 in the world to disclose clinical efficacy and safety data for indications of cervical cancer and esophageal carcinoma. 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.

According to GlobalData, there will be 123,846 cervical cancer cases in the eight major markets (UK, US, France, Germany, Spain, Italy, Japan, and urban China) by 2030.

Asieris Pharmaceuticals has announced positive data indicating the Phase III trial of its cold light photodynamic drug-device combination Cevira (APL-1702) achieved its primary endpoint in participants with cervical high-grade squamous intraepithelial lesions (HSIL). HSIL are precancerous lesions linked to human papillomavirus (HPV) that can lead to cervical cancer. The results were presented at the 2024 Society of Gynecologic Oncology (SGO) Annual Meeting in San Diego, US, which was held 16-18 March. Cevira also demonstrated a tolerable safety profile. The therapy stimulates the body’s production of the photosensitiser protoporphyrin IX (PPIX), which selectively accumulates in tumour tissue, and upon exposure to specific wavelengths, triggers tumour cell apoptosis. The primary endpoint, which evaluated the response rate six months after administering Cevira, showed a statistically significant improvement of 89.4% compared to the placebo group. See Also: Dr. Reddy’s Laboratories files patent for 6-substituted pyridazine compounds for treating diseases dependent on SMARCA2/SMARCA4 The drug also showed an improved clearance rate of high-risk HPV16 and/or HPV18, with a 103.9% increase in the Cevira group compared to placebo. Cevira was developed through Phase I and II clinical trials by Norway-based Photocure ASA, with Asieris gaining commercialisation rights in July 2019. The Phase III trial (NCT04484415) enrolled 402 HSIL patients, defining the primary endpoint of response as the conversion of cervical epithelial tissue pathology to normal, or the conversion to low-grade squamous intraepithelial lesion (LSIL) while achieving baseline HPV clearance. Long-lasting infection with certain types of HPV, a common sexually transmitted infection, is the main cause of cervical cancer. If left untreated, HPV can be linked to 95% of cervical cancer cases, according to the World Health Organization. The China-based biotech now plans to submit a new drug application for Cevira in Q2 2024, according to Asieris’ chief development officer Linda Wu. According to a report on GlobalData’s Pharma Intelligence Center, the number of cervical cancer cases in the eight major markets (UK, US, France, Germany, Spain, Italy, Japan, and urban China) will reach 123,846 by 2030. GlobalData is the parent company of Clinical Trials Arena. In the announcement accompanying the data, Linda Wu said: “The study not only demonstrates remarkable efficacy but also exhibits a favourable safety profile, offering a new powerful artillery for the national cervical cancer prevention and control system. “Additionally, we are making significant progress in product development overseas, aiming to bring this innovative treatment to more patients as soon as possible.” The company also has other cancer candidates in the pipeline. Earlier this year, a Phase II trial of its repurposed antibiotic drug APL-1202 achieved its primary endpoint in participants with muscular invasive bladder cancer (MIBC). The drug is already approved to treat oesophagal squamous cell carcinoma in China and is also being reviewed by the US Food and Drug Administration to treat the same type of cancer.

CEL-4000 may deliver safe and effective therapy for RA by rebalancing the inflammatory response, without weakening important immune defense mechanisms, risking infections or cancer, as current treatments may VIENNA, Va.--(BUSINESS WIRE)-- CEL-SCI Corporation (NYSE American: CVM) today announced the peer reviewed scientific journal Frontiers in Immunology published an article regarding CEL-SCI’s Ligand Epitope Antigen Presentation System (LEAPS) technology in the treatment of rheumatoid arthritis (RA) titled: “Current status of immunological therapies for rheumatoid arthritis with a focus on antigen-specific therapeutic vaccines”. CEL-SCI’s LEAPS team, along with outside collaborators from U.S. and Europe, reviewed published/presented results from pre-clinical animal model of antigen-specific LEAPS therapeutic vaccines, such as CEL-4000 and CEL-5000, made specific for the treatment of RA, and compared these findings with published results of other RA-therapies that either suppress or alter the immune response in order to treat RA. In the article, the authors note that the currently available therapeutic arsenal for the treatment of RA consists mainly of immunosuppressive or ablative drugs, which may carry the potential risk of facilitating recurrent or primary infectious diseases or cancer. They also underscore that a therapeutic vaccine that can rebalance the inflammatory disease process, promoting antigen-specific disease-directed T cell immune responses, is highly desirable. CEL-4000, an antigen specific immunomodulating vaccine, is provided as a new treatment paradigm that should deliver therapy for RA without weakening important immune defense mechanisms against microbial infections or cancer. The authors also emphasized that the most appropriate way to advance the LEAPS vaccines to the clinic would be an adaptive study design for clinical trials, enrollment of patients with early-stage RA, and using the Bayesian optimal design model, currently used in oncology studies, as well as the use of disease-related biomarkers to ascertain responsiveness to treatment and introduce additional tools to assess outcome at the disease level. “At CEL-SCI, we focus on utilizing a healthy immune system to overcome disease safely and with minimal side effects. Our LEAPS platform, and CEL-4000 specifically approaches the treatment of auto immune diseases like rheumatoid arthritis in a completely different way. By rebalancing the immune system to its original healthy state, CEL-4000 could protect patients from the risk of cancer and infection,” stated CEL-SCI CEO, Geert Kersten. “The growing body of preclinical data on LEAPS supports the advancement of this asset into human studies.” About CEL-SCI Corporation CEL-SCI believes that boosting a patient’s immune system while it is still intact should provide the greatest possible impact on survival. Multikine* (Leukocyte Interleukin, Injection) is designed to help the immune system "target" the tumor at a time when the immune system is still relatively intact and thereby thought to be better able to mount an attack on the tumor. In a Phase 3 study, CEL-SCI studied patients who were newly diagnosed with locally advanced primary squamous cell carcinoma of the head and neck (oral cavity and soft-palate) with the investigational product Multikine administered first, before they received the standard of care, which involved surgery followed by either radiation or chemoradiation. The Phase 3 study enrolled 928 patients. Our approach is unique because most other cancer immunotherapies are administered only after conventional therapies have been tried and/or failed. After analyzing data from the Phase 3 study, we have better defined the target head and neck cancer population for Multikine, which is advanced primary head and neck cancer patients with no lymph node involvement and with low PD-L1 tumor expression. In the Phase 3 study, we observed statistically significant survival data in the final target population, showing that Multikine cut the risk of death in half at five years vs control. We plan to submit the proposed study protocol to the FDA in Q1 2024, with the goal to get FDA buy-in for a confirmatory clinical trial, and also to discuss potential accelerated approval pathways. Multikine (Leukocyte Interleukin, Injection) received Orphan Drug designation from the FDA for neoadjuvant therapy in patients with squamous cell carcinoma (cancer) of the head and neck. The Company has operations in Vienna, Virginia, and near/in Baltimore, Maryland.
