SUZHOU, China, May 6, 2024 /PRNewswire/ -- Alphamab Oncology (stock code: 9966.HK) announced that data from the clinical study conducted in China (JSKN003-102) of anti-HER2 bispecific antibody-drug conjugate (ADC) JSKN003 for the treatment of HER2-expressing advanced solid tumors, will be presented for the first time at the 2024 Annual Meeting of American Society of Clinical Oncology (2024 ASCO Annual Meeting) from May 31 to June 4, 2024, in Chicago, IL, U.S..
Title:Evaluation of the safety, pharmacokinetics, and efficacy of JSKN003 in patients with advanced solid tumors: A phase I/II clinical study
Abstract Number for Publication: 3031
Session Type and Title: Poster Session - Developmental Therapeutics -Molecularly Targeted Agents and Tumor Biology
Session Date and Time: 6/1/2024 9:00 AM-12:00 PM CDT
JSKN003, an anti-HER2 bispecific antibody-drug conjugate (bis-ADC), developed inhouse with proprietary Glycan-specific conjugation platform, shows better serum stability which may lead to a broader therapeutic window. The data of the phase I clinical trial conducted in Australia presented at the 2024 Annual Meeting of American Association for Cancer Research (AACR) in April demonstrated favorable tolerability, safety profile and encouraging preliminary anti-tumor activity. Multiple clinical studies of JSKN003 are currently being conducted in Australia and China, and we are also actively making the progress in its pivotal clinical trial in advanced HER2 low-expression breast cancer in China.
JSKN003-102 (NCT05744427) is a phase I (dose escalation and expansion) and phase II (cohort expansion) clinical study in Chinese patients with advanced solid tumors. Patients with histologically documented HER2-expressing (IHC≥1+) or patients with HER2-mutant cancers who failed prior systemic therapies were recruited and received JSKN003 monotherapy in phase I study. The objectives were safety, pharmacokinetics (PK), preliminary antitumor activity of JSKN003 and to determine the maximum tolerated dose (MTD) or the recommended phase II dose (RP2D). The results of the phase I study will be presented at this ASCO Annual Meeting.
About JSKN003
JSKN003 is an anti-HER2 bispecific antibody-drug conjugate (bis-ADC), which is developed inhouse with proprietary Glycan-specific conjugation platform. JSKN003 targets HER2 and triggers internalization and release the cytotoxic drug. Compared with its counterparts, JSKN003 demonstrated better serum stability, stronger bystander effect and comparable tumor killing activity, which effectively expands the therapeutic window. Multiple clinical studies of JSKN003 are currently being conducted in Australia and China, and we are also actively making the progress in its pivotal clinical trial in advanced HER2 low-expression breast cancer in China.
