Renal and Hematologic Comparative Effects of Dissociated Agonist of the Glucocorticoid Receptor and Prednisone in Dogs With and Without Food Restriction.

Glomerulopathy and body weight gain were noted after chronic oral administration of a novel nonsteroidal dissociated agonist of the glucocorticoid receptor compound, fosdagrocorat, to beagle dogs fed an ad libitum diet. To further investigate the role of diet and treatment with either fosdagrocorat or the glucocorticoid comparator, prednisone, on renal safety, a 13-week investigative study was conducted in beagle dogs. Renal histopathology, clinical chemistry, urinalysis, glomerular filtration rate (GFR), body weight, heart rate, blood pressure (BP), and hematology were investigated in restricted- and ad libitum-fed dogs administered prednisone (2.

Design and synthesis of long acting inhaled corticosteroids for the treatment of asthma.

In this Letter we present data for a novel series of ICS for the treatment of asthma. 'Inhalation by design' principles have been applied to a series of highly potent steroidal GR agonists, with a focus on optimising the potential therapeutic index in human. Pharmacokinetic properties were tuned with high intrinsic clearance and low oral bioavailability in mind, to minimise systemic exposure and reduce systemically driven adverse events.
