Antengene Corporation Limited, a leading innovative biopharmaceutical company dedicated to discovering, developing and commercializing global first-in-class and/or best-in-class therapeutics in hematology and oncology, today announced that it has submitted a New Drug Application (NDA) to the Taiwan, China Food and Drug Administration (TFDA) for selinexor, a first-in-class XPO1 inhibitor, for three indications: in combination with bortezomib and dexamethasone (XVd), or in combination with dexamethasone (Xd) for the treatment of patients with relapsed and/or refractory multiple myeloma (RRMM); and as monotherapy in adult patients with relapsed and/or refractory diffuse large B-cell lymphoma (rrDLBCL), including DLBCL arising from follicular lymphoma, who have received at least two lines of systemic therapy.
Antengene has submitted New Drug Applications (NDAs) for selinexor in multiple Asia Pacific markets including China, Australia, South Korea, and Singapore, and was granted Priority Review status by China's National Medical Products Administration (NMPA) and Orphan Drug Designation by the Ministry of Food and Drug Safety of South Korea (MFDS). This NDA submitted in Taiwan, China marks another milestone in Antengene's expansion in the APAC markets and the company's effort to address the unmet clinical needs of patients with hematologic malignancies.
Dr. Jay Mei, Founder, Chairman and CEO of Antengene, commented: "Within just nine months, we have submitted NDAs in six APAC markets, demonstrating our commitment to addressing the unmet needs of patients in the APAC region. Our seasoned team has a wealth of experience and depth of insight in product registration and commercialization in the Asia Pacific markets. I am confident that Antengene will deliver on our promise to bring our portfolio of innovative therapies to patients in the APAC markets."
"Selinexor is an anti-tumor drug with a highly novel mechanism of action. It has been approved by the FDA for three indications in two tumor types (MM and DLBCL) in less than two years, demonstrating its broad anti-tumor effects," said Kevin Lynch, Chief Medical Officer of Antengene. "Selinexor treatment in combination with dexamethasone still has 25.3% overall response rate (ORR) in patients who have failed five established therapies (penta-refractory) myeloma; and for patients with multiple myeloma who received at least one prior line of treatment, the median progression-free survival (PFS) is 13.9 months, which is significantly higher than that of the control group receiving bortezomib-based standard of care. In the subgroup analysis, patients who are 65 years or older, with renal insufficiency or high-risk cytogenetics can still achieve significant benefits from the XVd regimen. These are patients who are otherwise very difficult to treat. Finally, selinexor monotherapy can enable patients with rrDLBCL to obtain deep and durable responses with a median duration of response of 23.0 months for patients with complete response. We are therefore very optimistic about the potential efficacy benefits of selinexor combination regimens in DLBCL."
Antengene and Karyopharm Therapeutics Inc. (NASDAQ: KPTI) have entered into an exclusive collaboration and license agreement for the development and commercialization of selinexor and other two XPO1 inhibitors, and a PAK4/NAMPT inhibitor in 17 APAC markets including Mainland China.
