“The subsequent toxicology study was initially programmed for 26 weeks of treatment but due to declining clinical condition that necessitated early sacrifice of a number of animals for welfare reasons, the study was stopped after 9 (total of 9 doses; 20 mg/kg group) or 14 weeks”
Pivotal GLP studies
GLP cynomolgus 5-week IV (0.1/1/10 mg/kg, 12-wk recovery) and 9- or 14-week IV (1/5/20 mg/kg, 13-wk recovery) studies
