Hello there.I think that here are possibly a very few people,who do understand how toxicology studies are conducted.From the Petri dish and slides under the microscope analysis and if results are good(in vitro studies) the animals are dosed with the substance/compound by injecting it or orally ,topically or rectally .Major pharmaceutical laboratories have resources to do all of the above at the same time on the same species ,which in turn are divided into those subgroups.This saves time and the study is finished quicker.However smaller labs may not have the resources or manpower to do it that way and start in vivo studies with the injections.This guarantees that various doses are delivered to all animals exactly.If there is a good response/results obtained and toxic effects are absent,minimal or acceptable, other routs of delivery are tested subsequently.For iv/im stuff, solubility is paramount.If toxic effects are unacceptable in the lab animals,you can not apply for a clinical trial.This is why I said we need to know why toxicology studies are taking so long.Why not tell us for instance that toxic effects of injections(whilst compound was very effective) forced SAR to test other forms of drug delivery.Most reasonable shareholders would understand that.This now will take some additional time and the expense.Maybe two rich individuals were informed about it and invested here.ATB - Stach
