Alphamab Oncology will update the research results of several core pipeline products at the 2023 ESMO Annual Meeting

SUZHOU, China, Aug. 10, 2023 /PRNewswire/ -- Alphamab Oncology (stock code: 9966.HK) announced that posters to highlight the company's core pipeline products, PD-L1/CTLA-4 bispecific antibody KN046 and HER2 bispecific antibody KN026, will be announced at the 2023 European Society for Medical Oncology (ESMO) Congress.

KN046

KN046, a BsAb immune checkpoint inhibitor simultaneously targeting two clinically-validated immune checkpoints, PD-L1 and CTLA-4, representing a potential breakthrough, next-generation immuno-oncology blockbuster drug. Currently, there are approximately 20 clinical trials of KN046 in different stages covering more than 10 types of tumors including NSCLC, TNBC, ESCC, HCC, PDAC and Thymic carcinoma in China, the United States and Australia. The results of these clinical trials have demonstrated a preliminary profile of good safety and promising efficacy of KN046.The ESMO Conference will present four clinical research results of KN046.

KN026

KN026 is an anti-HER2 bispecific antibody that can bind two non-overlapping epitopes of HER2 simultaneously, leading to potentially superior efficacy. KN026 has superior anti-tumor activity and good safety than the combination of trastuzumab and pertuzumab, and is currently undergoing a number of clinical trials in different stages in China and the United States. The ESMO Conference will present two clinical research results of KN026.

Title: Two-year follow-up data on the efficacy and safety of KN026, a HER2-targeted bispecific antibody combined with docetaxel as first-line treatment for HER2-positive recurrent /metastatic breast cancer

About KN046

KN046 is PD-L1/CTLA-4 bispecific antibody independently developed by Jiangsu Alphamab. Its innovative designs include: a novel mechanism - CTLA-4 fused with PD-L1 single domain antibody; engineered to target the tumor microenvironment with high PD-L1 expression, and Treg (suppress tumor immunity) clearing function.

There are about 20 clinical trials of KN046 in different stages covering more than 10 types of tumors including NSCLC, pancreatic cancer, thymic cancer, HCC, ESCC and TNBC in Australia, the US and China. The results of these clinical trials have shown an advantage in survival for patients. Alphamab Oncology has received FDA clearance to enter phase II trial of KN046 based on the clinical results in China and Australia. Moreover, KN046 has obtained the U.S. FDA's orphan drug designation for thymic epithelial tumor in September 2020. Several pivotal clinical trials are currently being conducted, among which the interim analysis of the phase III clinical study of KN046 combined with chemotherapy as the first-line treatment of NSCLC successfully met the prespecified PFS endpoint.

About KN026

KN026 is an anti-HER2 bispecific antibody that can bind two non-overlapping epitopes of HER2 simultaneously, leading to a dual HER2 signal blockade. KN026 has demonstrated potentially superior efficacy to Trastuzumab and Pertuzumab in combination, such as increased binding affinity, as well as better tumor inhibition in HER2-positive tumor cell lines. Additionally, KN026 has also shown inhibitory effect on tumor cells with medium or low HER2 expression or Trastuzumab-resistant cell lines.

Alphamba already initiated multiple clinical trials for KN026 in China and the United States. KN026 showed good efficacy and safety profiles, even in heavily pretreated patients with HER2-positive breast cancer and gastric cancer. Currently, several phase III pivotal studies of KN026 are ongoing for patients with breast cancer, or gastric cancer/gastroesophageal junction cancer, etc.

In August 2021, the company entered an agreement with JMT-Bio, a wholly-owned subsidiary of CSPC Pharmaceutical Group Co., Ltd. (stock code: 1093.HK), for the development and commercialization of KN026 in Mainland China. According to the terms of the agreement, JMT-Bio will obtain the exclusive license rights of KN026 for the development and commercialization in the indications of breast cancer and gastric or gastroesophageal junction cancers (GC/GEJ) in Mainland China (excluding Hong Kong, Macau and Taiwan).
