The types of information required to be disclosed on Form 8-K are generally considered to be “material.” That means that, in general, there is a substantial likelihood that a reasonable investor would consider the information important in making an investment decision.

I'm with you in questioning why there have been no other sources for this information. I don't understand the timing of the PR unless it was needed to put in an 8-k for clerical reasons with the uplist to the NASDAQ.
There is a reason the NIAID has not specifically stated the drug name of the monoclonal antibody they are testing, I'm just speculating as to why that would be. What we do know is that the head of the NIAID just stated that a trial of a monoclonal antibody was initiated this week & HGEN announced they were selected for a trail with the NIAID this week.
