Safety evaluation of the interchangeable use of robenacoxib (Onsior™) tablets and solution for injection in dogs.
Robenacoxib (Onsior™) is a non-steroidal anti-inflammatory drug developed for canine and feline use for the control of pain and inflammation. It is available as both tablets and solution for injection. The objective of this safety study was to investigate the interchangeable use of two robenacoxib formulations in dogs using a novel study design alternating between oral tablets and subcutaneous injections. Thirty-two naïve healthy 4-month dogs were enrolled in this 88-day study and were randomized among four groups to be untreated or to receive robenacoxib at the highest recommended or elevated dose rates. The dogs were administered three 20-day treatment cycles each separated by a 14-day washout period. Each 20-day cycle was comprised of 10 days of once daily oral administration, 3 days of subcutaneous administration, followed by further 7 days of oral administration (Groups 2 to 4). The control group (Group 1) received oral empty gelatin capsules or subcutaneous saline injections. Assessment of safety was based on general health observations, clinical observations, physical and neurological examinations including ophthalmological examinations, electrocardiographic examinations and clinical pathology evaluations, food and water consumption, body weight, and macroscopic and microscopic examinations. Blood samples were collected for pharmacokinetic evaluation.. Blood concentrations of robenacoxib confirmed systemic exposure of all treated dogs. All dogs were in good health through study termination and there were no serious adverse events during the course of the study. No changes in body weight, food consumption, ophthalmic, neurological examinations, electrocardiograms, buccal mucosal blood times, clinical pathology or organ weight were attributable to robenacoxib formulation administration. Primary treatment-related abnormalities were of low incidence at all doses. They were confined to macroscopic and microscopic changes observed locally at the subcutaneous injection sites and microscopic findings within the gastrointestinal tract. These findings were as expected based on previous studies with robenacoxib solution for injection alone and the known properties of this class of compound and mode of administration. There were no adverse effects which could be attributed specifically to the interchangeable use of oral and injectable robenacoxib.. Alternating regimens of robenacoxib tablets and solution for injection were well tolerated in healthy young dogs.

Population pharmacokinetic analysis of blood concentrations of robenacoxib in dogs with osteoarthritis.
The purpose of this analysis was to investigate whether the recommended daily dosage of 1-2mg/kg robenacoxib provides consistent exposure when administered to dogs with chronic osteoarthritis (OA), and the need for dose adjustment in special patient populations. Data from three prospective, multi-center field studies in 208 OA dogs were analyzed using non-linear mixed effects modeling. A model based assessment was performed with stepwise inclusion and exclusion of population characteristics to explain between-subject variability, and assess the according necessity for dose adjustment. Only the influence of bodyweight on both apparent clearance and volume were found to be significant (p<0.01). No significant influence of sex, age and breed, or kidney and liver variables was identified in this representative sample of OA dogs. The population pharmacokinetic analysis performed showed that the 1-2mg/kg dosage chosen provided consistent robenacoxib exposure in a wide range of canine patients. No other dose adjustment seems necessary.
