Acetylcysteine zidrimer is under clinical development by Orpheris and currently in Phase I for Parkinson’s Disease. According to GlobalData, Phase I drugs for Parkinson’s Disease have a 72% phase transition success rate (PTSR) indication benchmark for progressing into Phase II. GlobalData’s report assesses how Acetylcysteine zidrimer’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.

Acetylcysteine zidrimer overview

Acetylcysteine zidrimer (OP-101) is under development for the treatment of childhood cerebral andrenoleukodystrophy (ccALD), Parkinson's disease, Amyotrophic lateral sclerosis (ALS), Alzheimer's disease (AD), hyperinflammation. It is administered through intravenous and subcutaneous route. The therapeutic candidate is a new chemical entity. It constitutes of hydroxyl poly (amidoamine) (PAMAM) dendrimer conjugated to N-acetyl cysteine (NAC) with a glutathione (GSH)-cleavable disulfide linkers. It is acts by targeting ikappaB kinase and nuclear factor kappa B and developed based on hydroxyl dendrimer technology.

It was also under development for the treatment of cerebral palsy, Huntington disease, neonatal brain injury (NBI) and other neuroinflammatory diseases and  coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), hypoxemia and acute respiratory distress syndrome.
