Oral Formulations Of Cytidine Analogs And Methods Of Use Thereof

Patent No. EP3782611 (titled "Oral Formulations Of Cytidine Analogs And Methods Of Use Thereof") was filed by Celgene on May 14, 2009. The application was issued on Jul 6, 2022.

Patent Summary

Oral formulations of cytidine analogs like 5-azacytidine for treating diseases like cancer and myelodysplastic syndromes. The formulations release the drug substantially in the stomach following oral administration. This allows higher drug levels and improved absorption compared to enteric-coated formulations. The compositions are immediate release tablets or capsules without enteric coating. They may contain excipients, permeation enhancers, or vitamin E derivatives. The formulations aim to provide oral convenience and potentially improve therapy by enabling higher doses, longer treatment durations, and better safety/efficacy profiles compared to parenteral administration.
