Details on IHL clinical trials, page-89

Quick question for the experts in this group.

Our IHL-675A SAARDS clinical trials. We obviously completed the first animal trials a few months ago, and we just released some data from the in vitro study does this mean we have moved onto the last animal trial already or are we still waiting for more information from the last in vitro study?
I've got a little confused by the recent ann, its my understanding the last trial (animal studies) is to find the optimum dosage for usage now that we know that it works. Has this begun?

Thanks holders.
