Question 1

What is Xpovio?

Accepted Answer

Xpovio is a medication classified as a selective inhibitor of nuclear export (SINE). It functions by blocking a protein called exportin 1 (XPO1), which normally transports other proteins out of the nucleus of a cell.

By preventing this transport, the drug helps retain tumor suppressor proteins within the nucleus. This process can help slow the growth of cancer cells and trigger their natural destruction.

Question 2

What is Xpovio used for?

Accepted Answer

Xpovio is used to treat diffuse large B-cell lymphoma and multiple myeloma .

Question 3

How does Xpovio work?

Accepted Answer

Mechanism of Action

Xpovio belongs to a class of medications known as selective inhibitors of nuclear export (SINE). It works by blocking a specific protein in the body called exportin 1 (XPO1).

In a healthy cell, XPO1 helps transport various proteins from the nucleus (the center of the cell) to the cytoplasm (the outer part of the cell). However, in many types of cancer, XPO1 is overactive and moves tumor suppressor proteins out of the nucleus too quickly. These tumor suppressor proteins are necessary to identify damaged cells and prevent them from multiplying uncontrollably.

By blocking XPO1, Xpovio keeps these tumor suppressor proteins trapped inside the nucleus. Once they accumulate in the nucleus, they can perform their job of:

Identifying and repairing damaged DNA.

Stopping the cancer cell from dividing and growing.

Triggering a process called apoptosis, which is the programmed death of the cancer cell.

Because cancer cells often rely more heavily on XPO1 than healthy cells do, Xpovio is designed to target the cancer cells while having a different effect on normal, healthy cells.

Question 4

What are the active ingredients in Xpovio?

Accepted Answer

The active ingredient in Xpovio is selinexor .

Question 5

What are the side effects of Xpovio?

Accepted Answer

Common side effects of Xpovio may include:

Nausea

Fatigue

Diarrhea

and others.

Always consult with a healthcare professional about potential side effects.

Question 6

What drug class is Xpovio?

Accepted Answer

Xpovio belongs to the selective inhibitor of nuclear export drug class.

Question 7

What is the dosage of Xpovio and how do I take it?

Accepted Answer

How to Take Xpovio

Xpovio is taken by mouth, usually on specific days each week. Your healthcare provider will establish a schedule that may involve taking the medication once or twice weekly. It is important to follow this schedule exactly as prescribed.

Take the tablets at the same time on your scheduled days.

You may take the medication with or without food.

Swallow the tablets whole with water. Do not crush, chew, break, or dissolve them.

To help manage certain side effects, your doctor may prescribe additional medications to prevent nausea and vomiting. It is also important to drink plenty of fluids and maintain adequate salt intake while you are being treated with this medication.

Missed Dose

If you miss a scheduled dose, skip the missed dose and take your next dose at the regular time. Do not take extra medicine to make up for a missed dose.

If You Vomit

If you vomit shortly after taking a dose, do not take an additional dose to replace it. Wait until your next regularly scheduled dose to take the medication again.

Question 8

Is Xpovio safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Based on its mechanism of action and findings from animal studies, Xpovio can cause fetal harm when administered to a pregnant woman. There are no adequate studies of Xpovio use in pregnant humans to determine a drug-associated risk of birth defects or miscarriage. In animal studies, the medication caused embryo-fetal death and structural abnormalities at doses lower than the recommended human dose.

Healthcare providers typically verify the pregnancy status of individuals who can become pregnant before starting treatment. Because of the potential risks, the following precautions are generally recommended:

Females of reproductive potential: Use effective contraception during treatment and for one week after the final dose.

Males with female partners of reproductive potential: Use effective contraception during treatment and for one week after the final dose.

If you become pregnant or think you may be pregnant while taking this medication, notify your healthcare provider immediately.

Breastfeeding

It is not known whether Xpovio passes into human breast milk or if it affects milk production or the breastfed child. Because of the potential for serious adverse reactions in a nursing infant, it is advised that individuals do not breastfeed during treatment with Xpovio and for one week after the last dose.

Question 9

What forms and strengths does Xpovio come in?

Accepted Answer

Available Forms

Xpovio is available as a film-coated tablet for oral administration. The medication is typically supplied in blister packs designed to facilitate specific treatment cycles.

Question 10

What is the FDA approval status of Xpovio?

Accepted Answer

FDA Approval History

Xpovio, which contains the active ingredient selinexor, was first granted accelerated approval by the U.S. Food and Drug Administration (FDA) in July 2019. Initial approval was based on response rates in patients with heavily pretreated multiple myeloma. Subsequent approvals expanded its use for other indications based on further clinical data.

Approved Indications

The FDA has approved Xpovio for the following uses in adults:

Multiple Myeloma: Used in combination with bortezomib and dexamethasone for patients who have received at least one prior therapy. It is also approved for use with dexamethasone alone in patients who have received at least four prior therapies and whose cancer is resistant to several other classes of treatment.

Diffuse Large B-cell Lymphoma (DLBCL): Used as a single agent for patients with relapsed or refractory DLBCL, including cases arising from follicular lymphoma, after at least two lines of systemic therapy.

Regulatory Requirements and Monitoring

Xpovio is available only by prescription. While it does not have a Boxed Warning, the FDA requires specific monitoring during treatment due to the risk of serious side effects. Healthcare providers must monitor blood counts, liver function, and nutritional status regularly. Because some indications were approved under the accelerated approval pathway, continued approval for those uses may depend on the results of ongoing confirmatory trials.

Question 11

What should I know about Xpovio and cost?

Accepted Answer

Several variables determine the final price of Xpovio:

Insurance Coverage: Your out-of-pocket costs will depend on your specific health insurance plan, including your deductible, co-pay, or co-insurance requirements.

Dosage and Frequency: Xpovio is available in various strengths and dosing schedules. The total cost may change based on the number of tablets required for each cycle of treatment.

Pharmacy Type: This medication is often distributed through specialty pharmacies, which handle complex medications that require special storage or monitoring.

Xpovio is a brand-name medication containing the active ingredient selinexor. There is currently no generic version available. Generic drugs usually cost less than brand-name versions because they do not require the same initial research and development investment.

Patients who are prescribed Xpovio may have access to financial support options. These can include:

Manufacturer co-pay cards for patients with commercial insurance.

Patient assistance programs for those who are uninsured or underinsured.

Support from independent charitable foundations that help cover the cost of oncology medications.
