ATG-010 (selinexor) is the first and only oral selective inhibitor of nuclear export (SINE) compound in the world. In July 2019,the U.S. FDA approved selinexor in combination with low-dose dexamethasone for the treatment of adult patients with relapsed/refractory multiple myeloma (RRMM). In June 2020,selinexor was approved by the U.S. FDA as a treatment for patients with relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL). Currently,the registration clinical trials of ATG-010 in RRMM and R/R DLBCL are ongoing in China. The compound is also in late clinical development for various other hematologic malignancies and solid tumors (including KRAS mutant tumors). Pre-clinical studies demonstrated that inhibition of nuclear protein export through XPO1 can effectively treat tumors with such mutation.

ATG-008 (onatasertib) is a second-generation dual mTORC1/2 inhibitor presently studied in multi-regional clinical trials for the treatment of advanced hepatocellular carcinoma (HCC),as well as non-small-cell lung cancer (NSCLC),gynecological malignancies and other cancers as a single agent or in combination with an anti-PD-1 antibody.

ATG-016 (eltanexor) is a second-generation oral selective inhibitor of nuclear export protein XPO1 presently studied in myelodysplastic syndrome (MDS) as well as various types of solid tumors,such as colorectal cancer (CRC) and prostate cancer (PrC).

ATG-019 is a first-in-class PAK4/NAMPT dual-target inhibitor presently studied in a number of clinical trials including non-Hodgkin's lymphoma (NHL),colorectal cancer,NSCLC,and melanoma. In addition,pre-clinical studies have demonstrated that ATG-019 in combination with anti-PD-1 antibodies can effectively improve the anti-tumor activity and is effective in treating patients that become resistant to anti-PD-1 therapy.

ATG-527 (verdinexor) is an innovative compound in clinical studies as a potential treatment for anti-viral infection and autoimmune diseases – such as Epstein-Barr virus (EBV),respiratory syncytial virus (RSV) infection,cytomegalovirus (CMV) infection,systemic lupus erythematosus (SLE). Phase I healthy volunteer study of the compound has been completed.

ATG-017 is a potent and selective small molecule extracellular signal–regulated kinases 1 and 2 (ERK1/2) inhibitor in clinical development for the treatment of various solid tumors,non-Hodgkin's lymphoma,acute myeloid leukemia (AML) and multiple myeloma.

In addition,the Antengene drug discovery team is focused on the research and pre-clinical development of innovative small molecules,monoclonal and bi-specific antibodies to treat cancer.
