Antengene Corporation Limited ("Antengene") announced that the National Medical Products Administration (NMPA) accepted its New Drug Application (NDA) for ATG-010 (Selinexor, XPOVIO(R)), a oral selective inhibitor of nuclear export (SINE) compound, for the treatment of patients with relapsed/refractory multiple myeloma (rrMM). This is the fifth NDA for ATG-010 submitted by Antengene, after the four NDAs recently submitted in Australia, South Korea, Singapore and Hong Kong in the Asia Pacific region, and also the first NDA of SINE compounds in mainland China, a step closer to providing a novel option to Chinese patients diagnosed with hematological malignancies. Antengene has recently submitted NDAs in multiple markets for ATG-010 across three indications for multiple myeloma and diffuse large B-cell lymphoma. Recently, the National Comprehensive Cancer Network (NCCN(R)) has also added five ATG-010 regimens to its guidelines for multiple myeloma or diffuse large B-cell lymphoma. ATG-010 is the first approved SINE compound in the world. It induces the apoptosis of cancer cells in vitro and in vivo by causing the nuclear storage and activation of tumor suppressor proteins and other growth-regulating proteins, and by down-regulating the intracytoplasmic levels of various oncogenic proteins while normal cells are not affected. Clinical studies have demonstrated that ATG-010 has clinical effects in multiple types of hematological and solid tumors with manageable safety profile.
