What is the possibility some smart scientist will develop a synthetic KLH?
First, once an important ingredient is in an approved drug or vaccine or even has been approved for an early clinical study, that ingredient cannot be replaced without completely re-starting the study from scratch. (toxicity studies, safety studies, tolerance studies, manufacturing QT studies, contamination studies . . . . etc.) Second, because the injection of any new (especially medically-active) molecule into a human being requires years of study (typically 10 – 17 years) – first in mice for example, then a larger mammal like a pig, etc. and safety and effectiveness proven there before it can be even injected into humans – few would rationally start this very expensive and long process before there was confidence in a quite large market. Even then it would have to be proven in the specific use to which it was put (like conjugation to a particular cancer tumor target molecule) to it’s fair to say that this idea is 12 – 20 years away, at least. (It would be natural for Stellar and its
