• The approval of XPOVIO^® by the NHIS in South Korea is the fourth national reimbursement in the Antengene markets after mainland of China, Australia and Singapore.
• Additional reimbursements of XPOVIO^® in APAC markets are expected.

SHANGHAI and HONG KONG, June 26, 2024 /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 medicines for cancer, today announced that South Korea’s National Health Insurance Service (NHIS) has approved the reimbursement of XPOVIO^® (selinexor) for the treatment of adult patients with relapsed or refractory multiple myeloma (R/R MM). XPOVIO^® will be officially included into the national reimbursed drugs list of South Korea on July 1, 2024.

MM, the second most common hematologic malignancy, is caused by the dysregulated proliferation of plasma cells. Patients with MM face a range of challenges including a high relapse rate, short survival, and limited treatment options. According to market data, the global MM market has exceeded US$17 billion in 2023 and is expected to reach US$ 26 billion by 2028, with a compound annual growth rate (CAGR) of 8.7%^[1].

With a novel mechanism of action, XPOVIO^® is the world’s first approved orally-available, selective XPO1 inhibitor. XPOVIO^® has a global commercial presence with approvals in over 40 countries and regions.

To date, XPOVIO^® has already been included for health insurance coverage in mainland of China, Australia and Singapore in the APAC markets. With the latest approval from the NHIS in South Korea, XPOVIO^® is poised to be a novel treatment option and will bring clinically meaningful survival benefits to more patients in need.

Antengene has already submitted NDAs for XPOVIO^® in Thailand, Malaysia and Indonesia for the treatment of patients with R/R MM and R/R diffuse large B-cell lymphoma (R/R DLBCL).

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 multiple clinical studies of XPOVIO^® in the mainland of China for the treatment of relapsed/refractory hematologic malignancies and solid tumors (3 of these studies are being jointly conducted by Antengene and Karyopharm Therapeutics Inc. [Nasdaq:KPTI]).
