Once people have made up their mind about a stock, it's hard to change how they feel.
People that were left disappointed by the last trial will need a lot more positive news coming from this company before their minds can be changed.
The way I see it, this stock will keep getting treated as a scam until either new results are announced next year, or a partnership is announced before then.
Even then, I'm sure people will refuse to believe it until it's on the news and it's too late to get in.
