Aceneuramic acid (also known as N-Acetylneuraminic Acid, Neu5Ac, the UX 001 tablets) prolonged released had been filed a marketing authorization application with the European Medicines Agency by Ultragenyx in the EU for the treatment of hereditary inclusion body myopathy (HIBM), a rare, progressive muscle-wasting disease. This compound, a muscle protein stimulant, is also in phase II of the clinical trial for the treatment thrombocytopenia. In addition, recently was made studies, which had shown, that existed the significant positive correlation between serum and salivary sialic acid levels in oral squamous cell carcinoma (OSCC) patients.
