SHANGHAI and HONG KONG, Oct. 21, 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 Taiwan Food and Drug Administration (TFDA) has approved a New Drug Application (NDA) for XPOVIO® (selinexor) for three indications: (1) in combination with dexamethasone (Xd) for the treatment of adult patients with relapsed/refractory multiple myeloma (R/R MM) who have received at least four prior therapies and whose disease is refractory to at least two proteasome inhibitors (PIs), at least two immunomodulatory agents (IMiDs), and an anti-CD38 monoclonal antibody; or (2) in combination with bortezomib and dexamethasone (XVd) for the treatment of adult patients with MM who have received at least one prior therapy; and (3) as a monotherapy for the treatment of adult patients with relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL), not otherwise specified, including DLBCL arising from follicular lymphoma, after at least 2 lines of systemic therapy.
XPOVIO® is the world’s first oral selective inhibitor of the nuclear export protein XPO1, with regulatory approvals in 13 countries and regions including the United States, Israel, the United Kingdom, the European Union, Canada, Norway, Iceland, Lichtenstein, South Korea, Mainland China, Taiwan, Singapore and Australia. To date, multiple XPOVIO® regimens have been added to the clinical guidelines of major oncology societies in the U.S., the EU, and APAC, including 5 regimens for the treatment of myeloma and 1 regimen for the treatment of lymphoma added to the guidelines of the National Cancer Care Network (NCCN); 4 regimens for the treatment of myeloma and 1 regimen for the treatment of lymphoma added to the guidelines of the Chinese Society of Clinical Oncology (CSCO); 4 regimens for the treatment of myeloma added to the Guidelines for the Diagnosis and Management of Multiple Myeloma in China; 2 regimens for the treatment of myeloma added to the guidelines of the European Society of Medical Oncology (ESMO); and 1 regimen for the treatment of myeloma added to the guidelines of the International Myeloma Working Group (IMWG).
“Antengene is very pleased to receive regulatory approval for XPOVIO® in Taiwan for R/R MM and R/R DLBCL. There remains an unmet need to extend survival for patients with these life-threatening diseases and XPOVIO® presents Taiwan physicians and patients with a new novel addition to existing therapies. We continue to build our Antengene presence across APAC markets and in Taiwan. We also look forward to introducing XPOVIO® and securing reimbursement in order to extend access to this first in class therapy for our physicians and patients.”said Thomas Karalis, Antengene’s Corporate Vice President, Head of Asia Pacific Region.
“XPOVIO® is approved in multiple markets in the APAC region. This novel product fulfills Antengene’s mission to bring first-in-class/best-in-class medicines to patients with cancer in APAC markets and beyond,” said Mr. John Chin, Antengene’s Chief Business Officer. “Antengene is currently conducting eight clinical studies of XPOVIO® in mainland China for the treatment of patients with relapsed/refractory hematologic malignancies or solid tumors, and the drug’s safety and efficacy have already been validated in five registrational trials. Moving forward, we will strive to develop and commercialize more first-in-class and best-in-class drugs for patients with cancer or other life-threatening diseases.”
About Multiple Myeloma
Multiple myeloma (MM) is caused by the dysregulated proliferation of plasma cells. It is the second most common hematologic malignancy in many countries and regions. Despite availability of a number of treatments for relapsed patients, MM is prone to relapse and most patients still succumb to their disease. MM is the second most common hematologic malignancy in Taiwan, with an estimated about 700 to 800 new MM patients and 400 deaths per year[1].
About Diffuse Large B-Cell Lymphoma
Diffuse large B-cell lymphoma (DLBCL) is an aggressive hematologic malignancy and the most common subtype of lymphoma in Taiwan[2].
While there have been promising advances in therapy, options are limited, and effective treatment remains a challenge. Indeed, it is reported approximately 50% of patients with relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL) continue to lack effective treatment options[3].
About XPOVIO® (selinexor)
XPOVIO® is the world’s first approved orally-available, selective inhibitor of the nuclear export protein XPO1. It offers a novel mechanism of action, synergistic effects in combination regimens, fast onset of action, and durable responses.
By blocking the nuclear export protein XPO1, XPOVIO® can promote the intranuclear accumulation and activation of tumor suppressor proteins and growth regulating proteins, and down-regulate the levels of multiple oncogenic proteins. XPOVIO® delivers its antitumor effects through three mechanistic pathways: 1) exerting antitumor effects by inducing the intranuclear accumulation of tumor suppressor proteins; 2) reducing the level of oncogenic proteins in the cytoplasm by inducing the intranuclear accumulation of oncogenic mRNAs; 3) restoring hormone sensitivity by activating the glucocorticoid receptors (GR) pathway. To utilize its unique mechanism of actions, XPOVIO® is being evaluated for use in multiple combination regimens in a range of indications. At present, Antengene is conducting 8 clinical studies of XPOVIO® in mainland China for the treatment of relapsed/refractory hematologic malignancies and solid tumors (3 global clinical studies of these are being jointly conducted by Antengene and Karyopharm Therapeutics Inc. [Nasdaq:KPTI]).
XPOVIO® is approved in South Korea for the following two indications:

- As a monotherapy for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (R/R DLBCL), not otherwise specified, including DLBCL arising from follicular lymphoma, after at least 2 lines of systemic therapy.
