Ebselen is under clinical development by Sound Pharmaceuticals and currently in Phase III for Meniere Disease. According to GlobalData, Phase III drugs for Meniere Disease does not have sufficient historical data to build an indication benchmark PTSR for Phase III. GlobalData uses proprietary data and analytics to create drugs-specific PTSR and LoA in the Ebselen LoA Report. 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.

Ebselen overview

SPI-1005 (ebselen) is under development for the treatment of bipolar disorder, coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), mild to moderate noise-induced hearing loss (auditory threshold shift), Meniere's disease, and aminoglycoside-induced ototoxicity. The drug candidate is administered orally. It is a small molecule mimic of the enzyme glutathione peroxidase (Gpx). GPx is the dominant catalytic antioxidant enzyme that presents in the cochlea. it was also under development for chemotherapy in head and neck or non-small cell lung cancer induced hearing loss and tinnitus.
