Noble Life Sciences (Gaithersburg, MD), in collaboration with IBT Bioservices (Gaithersburg, MD), announces a newly optimized cotton rat model for preclinical studies of RSV (respiratory syncytial virus) therapies and vaccines. The companies jointly developed the model of RSV infection in the cotton rat and demonstrated its use to evaluate the efficacy of test compounds in RSV challenge studies.
Cotton rats are the gold standard for preclinical development of drugs and vaccines for RSV. The cotton rat gained importance for RSV studies because the permissiveness of cotton rats to infection with human RSV surpasses that of mice by more than 100-fold and because the model replicates several characteristic features of the human disease. Moreover, the predictive quality of the model is so high that treatments for severe disease advanced to clinical trials based on the results of efficacy and safety studies using cotton rats without the need for testing in primates.
