How is this HIV cure "project" to be classified, anyways? As I understood, this is not a classic FDA approved trial with an approved protocol, or? Is this approved or watched by FDA or any other agency?

In the past, silence from Nader on a specific trial or indication (like the HIV prep with Thailand red cross) was a good indication something went wrong or was stopped for another reason (e.g. GvHD).
I have no problem with not getting updates every two weeks about any small progress, enrollment or lost emails. What I expect as a shareholder is, to get informed about certain milestones (e.g. enrollment of first and last patient, trial stopped for whatever reason, ...) or other achieved/ received important regulatory decisions.
Make a plan, define milestones, communicate to shareholders, achieve milestones and report to shareholders in a timely manner.
No fluff, no golden quarter or three digits talk, no half backed PRs nobody can understand or interpret except the shorts.

I do not want the NWBO treatment (no news/ information at all), but I would expect professional communication from management on achieved goals or if a trial was stopped or started.
