Selinexor (Xpovio) has been approved for use in combination with dexamethasone for the treatment of select adult patients with relapsed refractory multiple myeloma (RRMM), the Food and Drug Administration announced in a statement.

The oral therapy was approved for patients who have received at least four prior therapies and whose disease is resistant to several other forms of treatment, including at least two proteasome inhibitors, at least two immunomodulatory agents, and an anti-CD38 monoclonal antibody, according to the FDA.

The approval provides a “treatment option for patients with multiple myeloma with no (other) available therapy,” said Richard Pazdur, MD, director of the FDA Oncology Center of Excellence and acting director of the Office of Hematology and Oncology Products in the FDA Center for Drug Evaluation and Research.

The approval was based on a study that included 83 patients with RRMM who had an overall response rate of 25.3% to Xpovio in combination with dexamethasone.

“The median time to first response was 4 weeks, with a range of 1-10 weeks. The median duration of response was 3.8 months. The efficacy evaluation was supported by additional information from an ongoing, randomized trial in patients with multiple myeloma,” according to the statement.

Common side effects seen in patients taking Xpovio in combination with dexamethasone include leukopenia, neutropenia, thrombocytopenia, and anemia. Patients also reported vomiting, nausea, fatigue, diarrhea, fever, decreased appetite and weight, constipation, upper respiratory tract infections, and hyponatremia.

Patients taking Xpovio should be monitored for low blood counts, platelets, and sodium levels, and should avoid other medications that may cause dizziness or confusion. Patients’ hydration status, blood counts, and other medications should be optimized to avoid dizziness or confusion. Females of reproductive age and males with a female partner of reproductive potential must use effective contraception during treatment with Xpovio. Women who are pregnant or breastfeeding should not take Xpovio.

Xpovio must be dispensed with a patient Medication Guide that describes important information about the drug’s uses and risks.

Xpovio in combination with dexamethasone was granted accelerated approval, and further clinical trials are required to verify and describe the drug’s clinical benefit.

The FDA granted the approval of Xpovio to Karyopharm Therapeutics.
