The clinical safety of ATOPICA for Cats was assessed in a masked, controlled 6-week field study followed by a 12-week open-labeled dose-tapering field study. In these two field studies, 205 cats received treatment with ATOPICA for Cats for up to 126 days. Two cats died or were euthanized within two weeks following study exit. One cat was diagnosed with the effusive form of feline infectious peritonitis and died following normal study exit, and one cat with pre-existing anemia that worsened during the study was diagnosed with aplastic anemia and euthanized because of a poor prognosis for recovery. Fourteen of the 205 cats (6.8%) were withdrawn from the studies due to the occurrence of an adverse reaction. Adverse reactions in these 14 cats included weight loss, anorexia, vomiting, diarrhea, hypersalivation, lethargy, hepatic lipidosis and jaundice, upper respiratory signs, ocular discharge, cough, toxoplasmosis, lymphopenia, anemia, bacterial dermatitis, seizure, ataxia, and small cell gastrointestinal lymphoma. The most commonly reported adverse reaction was vomiting. In most cases, vomiting spontaneously resolved with continued dosing. Adverse reactions occurred most often with daily dosing compared to other dosing regimes. Adverse reactions reported with greater than 2% frequency in the two field studies. The following adverse reactions were reported in less than or equal to 2% of cats treated with ATOPICA for Cats in the two field studies: bacterial dermatitis, hepatic lipidosis and jaundice, gastrointestinal small cell lymphoma, constipation, cough, toxoplasmosis, muscle wasting, muscle tremors, ataxia, convulsion, polyuria, urinary tract infection, inappropriate urination or defection, seborrhea, worsening otitis externa, papilloma, leukotrichia (whitening of hair) and excessive hair growth, anemia, lymphopenia, worsening monocytosis, worsening neutrophilia, hyperglobulinemia, increased serum creatinine and urea nitrogen, and increased alanine aminotransferase.

Cyclosporine is an immunosuppressive agent that has been shown to work via suppression of T-helper and T-suppressor cells and inhibition of interleukin-2. It does not depress hematopoesis or the function of phagocytic cells. ATOPICA for Cats is not a corticosteroid or antihistamine. Following an intravenous dose of 2 mg/kg in a 24-hour fasted state, clearance of cyclosporine A in cats was 0.199 L/kg x h and half life was ~24 hours. After oral administration, the terminal elimination half life has been estimated to be as short as 6.8 to longer than 40 hours in some normal healthy cats. The bioavailability of ATOPICA for Cats is highly variable both within and between cats. A pharmacokinetic study showed no consistent difference in the mean extent of drug absorption when administered orally to fed or fasted cats or mixed in with food. Blood levels of cyclosporine in field studies were highly variable, even among cats with similar clinical response, suggesting no generalizable correlations can be made between cats with regard to blood cyclosporine levels and clinical response (effectiveness and safety). Nevertheless, individual differences in the relationship between drug exposure and clinical response may exist. Therefore, to minimize individual fluctuations in drug absorption, ATOPICA for Cats should be administered on a consistent schedule with regard to meals and time of day.
