- ATG-101 is a novel PD-L1/4-1BB bispecific antibody. It is Antengene’s first in-house developed molecule with global rights.
- ATG-101 demonstrates potent in vivo efficacy in anti-PD-1/PD-L1 resistant mouse tumor models.
SHANGHAI and HONG KONG, Aug. 2, 2022 /PRNewswire/ — Antengene Corporation Limited (“Antengene” SEHK: 6996.HK), a leading innovative, commercial-stage global biopharmaceutical company dedicated to discovering, developing and commercializing first-in-class and/or best-in-class therapeutics in hematology and oncology, today announced that the first patient has been dosed in the Phase I PROBE-CN trial to evaluate ATG-101 as a monotherapy in patients with advanced/metastatic solid tumors or B-cell non-Hodgkin lymphoma (B-NHL) in China.
Shanghai East Hospital of Tongji University is the lead site for the study, which will be conducted at four centers across China. This open-label, multicenter Phase I study is designed to assess the safety and tolerability of intravenously administered ATG-101 monotherapy in patients with advanced/metastatic solid tumors and B-NHL. The study will be conducted in two parts (dose-escalation and a dose-expansion).
ATG-101 is a novel PD-L1/4-1BB bispecific antibody that was designed to block the binding of immunosuppressive PD-1/PD-L1 and conditionally induce 4-1BB stimulation, thus activating anti-tumor immune effectors, while delivering enhanced anti-tumor activity, with an improved safety profile. In preclinical studies, ATG-101 demonstrated significant anti-tumor activity in animal models of resistant tumors as well as those that progressed on anti-PD-1/L1 treatment. Furthermore, ATG-101 has also shown an excellent safety profile in Good Laboratory Practice (GLP) toxicology studies.
