Selinexor in Advanced Liposarcoma (SEAL)

Selinexor in Advanced Liposarcoma (SEAL)

Agents: Selinexor
Phase II/III
Status  Closed, active
Sponsor Karyopharm Therapeutics Inc


Further information: 


This is a randomized, multicenter, double-blind, placebo-controlled, Phase 2-3 study of patients diagnosed with advanced unresectable dedifferentiated liposarcoma (DDLS)

WHO is the trial for?

  • Patients of 12 years or older with confirmed DDLS
  • Disease needs treatment: Disease progression within 6 months before inclusion in study must be confirmed
  • Patients must have had at least two, but no more than five prior lines of systemic therapy for liposarcoma

WHAT is the key question that this trial is attempting to answer?

This study aims to investigate a drug called selinexor, a first-in-class, oral selective inhibitor of nuclear export (SINE). This trial tries to find out whether taking selinexor after treatment with at least two up to five prior therapies is effective and safe for patients who progressed on prior therapy.

WHY patients might want to participate?

In phase II of the study, half of the participanty will received selinexor, the other half received placebo. In phase III, two thirds of participants will receive selinexor, one third wil receive placebo. Patients, who might progress on placebo can receive/cross-over to the selinexor arm.

Phase II of this study is completed, phase III is ongoing.

 SPAEN Study Registry Selinxor SEAL DDLS
