IntraBio is a clinical-stage, global biopharmaceutical company that discovers, develops, and commercializes novel therapies for rare and neurodegenerative diseases. IntraBio is currently developing a series of small-molecule drug candidates that have broad applicability to rare and common neurological and inflammatory diseases.
IntraBio’s leading compounds, IB1000s, are a series of orally administered, modified amino-acid analogues that are well tolerated and have an excellent safety profile.
In clinical studies, IB1000 has been observed to have significant efficacy in the treatment of rare lysosomal storage disorders (LSDs) and common neurodegenerative diseases.
Based on the significant non-clinical data and promising findings from Phase 2 observational clinical studies, IntraBio is in the process of applying for multi-national, randomized, placebo-controlled clinical trials for the treatment of patients with Niemann-Pick type C, Tay-Sachs disease, and inherited Cerebellar Ataxias.
IntraBio will provide full details of its clinical programs, including enrollment and inclusion criteria for upcoming clinical trials, as soon as they become available.NEWS
Several publications have explored the mechanism of action of IB1000 in different model systems, listed below along with the published observational clinical study outcomes. In addition, there are several peer-reviewed papers that quantify the efficacy of IB1000 in the treatment of neurodegenerative diseases.
