“This is a transformational event for Axcynsis and a significant milestone for our proprietary ADC platform using AxcynDOT?,” said Dr. Zou Bin, CEO of Axcynsis. “We are pleased that FDA has cleared AT03-65 which leverages our AxcynDOT? technology for this first-in-human study. We are very excited with the potential of offering a transformative therapeutic option for patients with CLDN6-positive tumors as well as advancing our pipeline with differentiated and effective ADCs using AxcynDOT? to improve the lives of cancer patients worldwide”.
The upcoming Phase 1 multicentre clinical trial in the United States will evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and preliminary efficacy of AT03-65 in patients with advanced CLDN6-positive solid tumors.
关于AT03-65
AT03-65 is a recombinant anti-CLDN6 monoclonal antibody conjugated to AxcynDOT?, a proprietary payload developed by Axcynsis with a differentiated mechanism of action and broad anti-cancer activities. AT03-65 is designed to target advanced, recurrent, or metastatic CLDN6+ solid tumors in patients who have progressed on or after standard systemic treatment or for whom no standard therapies are available.
The antibody of AT03-65 is rationally engineered for high affinity and specificity to CLDN6. Upon binding to CLDN6-expressing tumor cells, the ADC is internalized into lysosomes, where it releases its payload to inhibit tumor growth effectively. Preclinical studies demonstrate that AT03-65 not only directly kill CLDN6-positive tumor cells but also exhibits bystander killing effect, targeting neighboring CLDN6-negative tumor cells to enhance its anti-tumor efficacy. AT03-65 has demonstrated promising anti-tumor activities in multiple tumor mouse models and a favorable safety profile in non-human primates.
