Abstract: Disclosed are polymers of hydroxypropyl methyl cellulose acetate succinate (HPMCAS) and hydroxypropyl methyl cellulose acetate (HPMCA) with unique degrees of substitution of hydroxypropoxy, methoxy, acetyl, and succinoyl groups. When used in making compositions comprising a low-solubility drug and such polymers, the polymers provide enhanced aqueous concentrations and/or improved physical stability.

Abstract: Methods and apparatus are disclosed for correcting measurements received by applying a frequency-varying signal with a measuring device (e.g., a permittivity probe) to a population of living cells (e.g., contained in a bioreactor) and correcting measurement divergences using data acquired using an alternate analytical method (e.g., trypan blue exclusion). In one example, a method comprises receiving electrical property data for a first population of cells, the data obtained by applying a first frequency-varying signal to the population with a measuring device, receiving biological property data obtained using an alternate analytical technique, generating at least one value representative of the frequency dependence of the electrical property data, and determining a relationship between the biological property data and the representative value. In some examples, measurements of apoptosis are predicted using the electrical property data.

Abstract: A composition comprises a solid dispersion comprising a low-solubility drug and at least one polymer. At least a major portion of the drug in the dispersion is amorphous. The polymer has a glass transition temperature of at least 100° C. measured at a relative humidity of fifty percent. Another aspect of the invention comprises the same composition except that the dispersion has a glass transition temperature of at least 50° C. at a relative humidity of fifty percent. In another aspect of the invention, a composition comprises a solid dispersion comprising a low-solubility drug and a stabilizing polymer. At least a major portion of the drug in the dispersion is amorphous. The composition also includes a concentration-enhancing polymer that increases the concentration of the drug in a use environment. The stabilizing polymer has a glass transition temperature that is greater than the glass transition temperature of the concentration-enhancing polymer at a relative humidity of 50%.

Abstract: A solid amorphous dispersion comprises a cholesteryl ester transfer protein (CETP) inhibitor, an inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG-CoA reductase inhibitor), and a concentration enhancing polymer. At least a major portion of the CETP inhibitor in the dispersion is amorphous. The solid amorphous dispersion provides concentration-enhancement of the CETP inhibitor when administered to an aqueous use environment.
