You don't hear anything from LP because it's not time to sell the benefits of DC-Vax to patients nor to investors. They have to just continue to walk the walk, quietly complete a full and complete MAA and BLA and get approved then only start selling the product, telling the world why and how soon Dc-Vax will be the new SOC for GBM and what that will mean financially for the company and for investors.
Do you hear a word from LP, DI or LG promoting the product or the company now? No, because that would be totally inappropriate. They aren't making promises to investors about when they will file for marketing approval, when they expect to get approved, how much revenue they expect when, etc. Why not? Because they have integrity. Because this is not a Theranos.
Do you want to blame them for having integrity? That's really stupid.
