Xpovio (Selinexor) 20mg Tablets — XPO1 Inhibitor for Multiple Myeloma & DLBCL | China | GLT

Generic Information: Xpovio (Selinexor) — China

Xpovio (generic name selinexor, Chinese brand 希维奥) is a first-in-class oral Selective Inhibitor of Nuclear Export (SINE) approved in Mainland China for the treatment of relapsed or refractory multiple myeloma (MM) and relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL). In China, Xpovio is commercialized by Antengene Corporation (德琪医药) under a partnership with the originator Karyopharm Therapeutics. This is the China-approved originator version, the same molecule as the US Xpovio, sourced directly through China's licensed distribution channel.

As the only approved oral XPO1 inhibitor in its class, Xpovio offers patients a genuinely different mechanism of action from proteasome inhibitors, immunomodulatory agents, and anti-CD38 antibodies — the three drug classes that heavily pre-treated myeloma patients have often already exhausted. That is precisely why selinexor matters for the relapsed/refractory setting: it works through a target no other approved myeloma drug touches.

What Is Xpovio (Selinexor)?

Xpovio is an oral tablet formulation of selinexor, a small-molecule drug that belongs to the SINE (Selective Inhibitor of Nuclear Export) family. Each tablet in the China version contains 20 mg of selinexor. It is taken by mouth, which is a meaningful convenience advantage over the injectable regimens that dominate multiple myeloma care. In China the drug is registered and distributed by Antengene Corporation, and it is the same originator product sold in the United States under the Xpovio name.

How Does Selinexor (XPO1 Inhibitor) Work?

Selinexor works by binding to and inhibiting XPO1 (Exportin-1, also called CRM1), the primary nuclear export protein in human cells. Cancer cells rely on XPO1 to shuttle tumor-suppressor proteins such as p53, p21, and IκB out of the nucleus, where they are then destroyed. By blocking this export, selinexor forces tumor-suppressor proteins to accumulate inside the nucleus, restoring their natural ability to halt cell growth and trigger apoptosis in malignant plasma cells. Because this mechanism is distinct from proteasome inhibition, IMiDs, and anti-CD38 antibodies, selinexor remains active even in disease that is refractory to those standard classes.

Indications for Xpovio (Selinexor)

• In combination with dexamethasone for adult patients with relapsed or refractory multiple myeloma (RRMM) who have received multiple prior therapies and whose disease is refractory to proteasome inhibitors, immunomodulatory agents, and an anti-CD38 monoclonal antibody.
• In combination with bortezomib and dexamethasone (XVd) for adult patients with multiple myeloma who have received at least one prior line of therapy.
• For relapsed or refractory diffuse large B-cell lymphoma (R/R DLBCL) in heavily pre-treated patients.

Dosage of Xpovio (Selinexor) 20 mg

The China version is supplied as 20 mg tablets. In the XVd regimen (with bortezomib and dexamethasone), the typical selinexor dose is 100 mg once weekly. In the Xd regimen (with dexamethasone alone), the dose is 80 mg on Days 1 and 3 of each week. Doses are rounded to the nearest available tablet strength, and the prescribing physician adjusts based on blood counts and tolerability. This product is available in 20 mg × 12 tablets and 20 mg × 16 tablets pack sizes.

Side Effects of Selinexor

The most important side effects to monitor are thrombocytopenia (low platelets), neutropenia (low white cells), and gastrointestinal toxicity including nausea, vomiting, diarrhea, and reduced appetite with weight loss. Hyponatremia (low blood sodium), serious infections, and neurological effects such as dizziness or confusion can also occur. Regular blood-count monitoring before and during treatment is essential. Patients should not drive until they know how the drug affects them.

Storage of Xpovio Tablets

Store Xpovio tablets at room temperature in the original packaging, away from moisture and direct light, and out of the reach of children. Do not remove the tablets from their blister pack until immediately before taking them.

Why Choose the China-Sourced Xpovio (Selinexor)?

For international buyers, the China-approved Xpovio offers a compelling value proposition. The China version is the same originator molecule, produced to NMPA quality standards and distributed through Antengene's licensed network, yet it is priced substantially lower than the US list price — roughly 70%–80% below the United States wholesale price, and meaningfully more affordable than in most Western European markets and Japan. This price gap reflects China's national reimbursement and pricing framework, which has driven the China cost down relative to US and European list prices. For institutional buyers and patients in regions where access is limited, sourcing Xpovio from China means obtaining the genuine originator drug at a fraction of the Western cost.
