On October 15, 2021 Antengene reported that The 36th Annual Meeting of the Society for Immunotherapy for Cancer (SITC 2021) will take place in Washington, D.C., United States, on November 10-14, 2021 (Press release, Antengene, OCT 15, 2021, View Source [SID1234591309]). The SITC (Free SITC Whitepaper)’s annual meeting is the world’s largest gathering in the field of immuno-oncology. The event is dedicated to promoting exchanges and collaborations in the field in order to improve treatment outcomes for cancer patients. At this year’s event, Antengene will release data of its PD-L1/4-1BB bispecific antibody, ATG-101, and its ERK1/2 inhibitor, ATG-017, in poster presentations both online and offline.

About ATG-101
ATG-101 is a novel PD-L1/4-1BB bi-specific antibody being developed for the treatment of multiple kinds of cancer. ATG-101 can activate anti-tumor immune effectors by simultaneously blocking the binding of PD-L1/PD-1 and inducing 4-1BB stimulation. In PD-L1 over-expressed cancer cells, ATG-101 has shown potent PD-L1 crosslinking-dependent 4-1BB agonist activity, thus potentially enhancing therapeutic efficacy, whilst mitigating risk of hepatoxicity. Antengene is currently conducting a Phase I study of ATG-101 in Australia for the treatment of patients with metastatic/advanced solid tumors and non-Hodgkin lymphoma.
About ATG-017
ATG-017 (AZD0364) is a potent and selective small molecule extracellular signal-regulated kinases 1 and 2 (ERK1/2) inhibitor. ERK1/2 are related protein-serine/threonine kinases that function as terminal kinases in the RAS-MAPK signal transduction cascade. This cascade regulates a large variety of cellular processes, including proliferation. The RAS-MAPK pathway is dysregulated in more than 30% of human cancers with the most frequent alterations being observed in RAS or BRAF genes across multiple tumor types. An ERK inhibitor enables the targeting of both RAS and BRAF mutant diseases. In nonclinical pharmacology studies, ATG-017 has demonstrated potent inhibition of ERK1/2 enzyme activity and tumor growth in vitro and in vivo. At present, Antengene is conducting a Phase I study of ATG-017 in Australia for the treatment of patients with advanced solid tumors and hematologic malignancies.
