Ritz, S., H. Egberink, et al. (2007). “Effect of feline interferon-omega on the survival time and quality of life of cats with feline infectious peritonitis.” J Vet Intern Med 21(6): 1193-7.
Feline infectious peritonitis (FIP) is a devastating disease of young cats with no known effective treatment. Feline interferon-omega (Virbagen Omega, Virbac) has been used in Europe and other parts of the world to treat FIP, but its efficacy is unknown. The drug is currently not available in North America. This study evaluated the efficacy of feline interferon-omega on the survival time and quality of life in 37 privately owned cats with naturally occurring FIP. The study was designed as a placebo-controlled double-blind trial. There was no statistical difference in the survival time or other variables in cats receiving feline interferon-omega compared to cats receiving placebo.
