Moby, a slippery slope, thee argument that safety isn't a pivotal part of every trial...and every prescription for that matter. Human safety in prescription medications is never assumed. It is axiomatic that a positive medication effect sometimes correlates with negative effects, and the patient may have to decide if side-effects are worth amelioration of the disease. In the biotech arena almost all safety data is obtained prior to human trials, and the inference of safety is always being reassessed in human use.
