Eltanexor is under clinical development by Karyopharm Therapeutics and currently in Phase II for Myelodysplastic Syndrome. According to GlobalData, Phase II drugs for Myelodysplastic Syndrome have a 30% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how Eltanexor’s drug-specific PTSR and Likelihood of Approval (LoA) scores compare to the indication benchmarks. Buy the report here.

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.

Eltanexor overview

Eltanexor is under development for the treatment of metastatic hormone refractory (castration-resistant, androgen-independent) prostate cancer, acute myeloid leukemia (AML), squamous cell carcinoma of the penis, nasopharyngeal cancer, myelodysplastic syndrome, adenocarcinoma of prostate and colon or rectum, relapsed or refractory multiple myeloma, metastatic colorectal cancer, refractory multiple myeloma, acute lymphoblastic leukemia, myelofibrosis, gastric cancer, gastroesophageal (GE) junction carcinomas, diffuse large B-cell lymphoma, triple-negative breast cancer (TNBC) and solid tumors. The drug candidate is administered orally. KPT-8602 acts by targeting exportin 1 and is a second generation SINE compound. The development is based on the selective inhibitor of nuclear export (SINE) technology platform. It was also under development for the treatment of acute myeloid leukemia (AML) and chronic lymphocytic leukemia (CLL).

GlobalData, the leading provider of industry intelligence, provided the underlying data, research, and analysis used to produce this article.

GlobalData’s Likelihood of Approval analytics tool dynamically assesses and predicts how likely a drug will move to the next stage in its clinical pathway (PTSR), as well as how likely the drug will be approved (LoA). This is based on a proprietary algorithm built from the drugs’ sales forecast, regulatory milestones, cost forecasts, WACC rate and other proprietary data sources found on GlobalData’s Pharmaceutical Intelligence Center.
