Not according to the United States Court of Appeals, citing Improved Pharma’s CSO Steve Byrn’s early paper on polymorph screening. The United States Court of Appeals for the Federal Circuit is known as the Supreme Court of patents, and its rulings are typically considered as significant landmarks in the patent and innovation field.

A recent paper by Testa et al., Int. J. Pharm., 556 (2019) 125, investigated the mixture analysis of Olanzapine, which crystallizes in more than 60 solid forms, using synchrotron X-ray diffraction. They suggested that synchrotron techniques could help guide the discovery of methods to prepare and analyze pure polymorphs. Their observations and suggestions are consistent Read more
At AAPS PharmSci 360, Improved Pharma found another exciting excipient for use in formulation. Like when SSCI was started, Improved Pharma was able to make several contacts at the AAPS meeting that will advance its problem-solving capabilities. One such advanced strategy is the utilization of calcium carbonate as an excipient to enhance dissolution. The excipient Read more
At AAPS PharmSci 360 it was clear that new excipients could be utilized to innovatively solve a range of amorphous dispersion/formulation problems. These new excipients provide significant strategy advances over conventional approaches and although our Improved Pharma scientists utilized a number of novel approaches to prepare amorphous dispersions while at SSCI, these new excipients provide Read more
As changes are made to the manufacturing process during drug development, it is often necessary to ensure that a drug or drug product made in a new way is the same as the material produced using the original methods. These equivalence studies often focus on chemical or physical properties and are relatively straight-forward for well-defined, Read more
One of the most critical parts of drug discovery and development is identifying the structure of the drug substance and drug product. For crystalline materials and biologicals it is routine to determine the arrangement of covalent bonds in the drug substance and drug product and the structure of the solid forms of the drug substance.
