Selinexor is under clinical development by Karyopharm Therapeutics and currently in Phase II for Leiomyosarcoma. According to GlobalData, Phase II drugs for Leiomyosarcoma have a 17% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how Selinexor’s drug-specific PTSR and Likelihood of Approval (LoA) scores compare to the indication benchmarks. Buy the report here.

Smarter leaders trust GlobalData

GlobalData tracks drug-specific phase transition and likelihood of approval scores, in addition to indication benchmarks based off 18 years of historical drug development data. Attributes of the drug, company and its clinical trials play a fundamental role in drug-specific PTSR and likelihood of approval.

Selinexor overview

Selinexor (Xpovio, Nexpovio) is an antineoplastic agent. It is formulated as film coated tablets for oral route of administration. Xpovio in combination with dexamethasone is indicated for the treatment of adult patients with relapsed or refractory multiple myeloma (RRMM) who have received at least four prior therapies and whose disease is refractory to at least two proteasome inhibitors, at least two immunomodulatory agents, and an anti-CD38 monoclonal antibody. Xpovio is indicated for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL), not otherwise specified, including DLBCL arising from follicular lymphoma, after at least 2 lines of systemic therapy. Xpovio in combination with bortezomib and dexamethasone is indicated for the treatment of adult patients with multiple myeloma who have received at least one prior therapy. It is also under development for the treatment of soft tissue sarcoma, osteosarcoma, leiomyosarcoma, pleomorphic liposarcoma, synovial sarcoma, epithelial ovarian cancer.

Selinexor (KPT-330) is under development for the treatment of light chain amyloidosis, anaplastic astrocytoma, diffuse intrinsic pontine glioma (DIPG), high-grade glioma (HGG), newly diagnosed advanced hepatocellular carcinoma, metastatic urothelial carcinoma, relapsed or refractory peripheral T cell lymphoma and natural killer T cell lymphomas, relapsed/refractory B-cell indolent non-Hodgkin lymphoma (R/R iHNL), malignant peripheral nerve sheath tumor (MPNST), leiomyosarcoma, endometrial stromal sarcoma, ovarian carcinoma, endometrial carcinoma, fallopian tube cancer, metastatic triple negative breast cancer, thymoma, non-small cell lung cancer, cervical carcinoma, melanoma, colon cancer, gastroenteropancreatic tumors, prolymphocytic leukemia, small lymphocytic lymphoma, recurrent glioblastoma, follicular lymphoma, mantle cell lymphoma, chronic lymphocytic leukemia (CLL), relapsed/refractory multiple myeloma (MM), relapsed and refractory acute myelogenous leukemia (AML), diffuse large B-cell lymphoma, chondrosarcoma, synovial sarcoma, liposarcoma, leiomyosarcoma, blast-crisis chronic myelogenous leukemia (bc-CML), relapsed and refractory Wilms tumor, rhabdoid tumor, malignant peripheral nerve sheath tumors, relapsed and refractory acute lymphoblastic leukemia, rectal cancer, lung cancer, gynecological cancer, Penta-refractory multiple myeloma, recurrent/refractory high-grade gliomas, myelofibrosis, primary myelofibrosis, Post-Polycythemia Vera Myelofibrosis, Post-Essential Thrombocythemia Myelofibrosis (Post-ET MF), Ewing sarcoma and myelodysplastic syndrome, gastrointestinal stromal tumor (GIST), non-small cell lung cancer and recurrent glioma. The drug candidate is administered orally as a tablet and topically as a gel. It is a SINE compound that acts by targeting CRM1 (chromosome region maintenance 1 protein, exportin 1 or XPO1). It is being developed based on Selective Inhibitor of Nuclear Export (SINE) compound technology.

It was also under development for the treatment of coronavirus disease 2019 caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), refractory or relapsed Richter's transformation, metastatic castrate-resistant prostate cancer, advanced squamous cell carcinoma of head and neck, lung cancer and esophageal cancer, relapsed/refractory cutaneous T cell lymphoma, relapsed small cell lung cancer, rectal adenocarcinoma, gastric cancer, metastatic colorectal cancer and diabetic foot ulcers.

It was also under development for the treatment of recurrent glioblastoma multiforme.
