$GLSI lets put on perspective something: greenwich IPO was in 2020 and 5 years later we are approching an interim analysis where i they can submit a BLA. tell me just one company you know, with the same timeline: IPO and then 5 years later a potencial IA which can lead to approval. you are aware that there are companies out there, with 25 years since IPO and no product right? and of course extreme dilution jajajaja. you may think, that things are going slow….quite the opposite my friends

$GLSI Regarding insider sales, there's no 30 day rule for all companies. Bottom line is the SEC can investigate as insider trading for any time frame. That's why public companies use Rule 10b5-1 (scheduled) trading plans. Large public companies most often do not allow any insider trades outside of their 10b5 plans. At this point in the Phase 3 trial and no updates since the April news releases and June interviews, Snehal certainly has some inside knowledge that has not been released to the public and therefore can't buy/sell without being scrutinized for insider trading. Don't expect any Snehal trades as glsi move towards interim data unless they first release an up-to-date public news release and Snehal waits a few days for it to cool down.

$GLSI if they are going to present an abstract on SABCS we will know in a few weeks jeje this is getting interesting and exactly, they will not present a bad or mediocre ( 5 vs 9) data in a conference that thousands of poeple follow each year.

$GLSI My guess is they show data at: SABCS Previously - data from their completed Phase IIb clinical trial at San Antonio Breast Cancer Symposium (SABCS): Presented at SABCS 2020. The final 5-year efficacy analysis, including Kaplan-Meier disease-free survival curves showing 100% survival (0% breast cancer recurrences, p=0.0338) in HER2/neu 3+ patients treated with GP2 + GM-CSF who completed the primary immunization series, compared to 89.4% in the placebo arm. They also presented further analysis of the same Phase IIb data, including immune response and its relationship to recurrence, at SABCS 2021. Earlier Phase I data from prior trials was referenced in company materials. These presentations supported the design and initiation of their ongoing Phase III trial (Flamingo-01), with posters on the trial design shared at SABCS 2020 and 2021.

$GLSI @Tetroman @doc123266 there is no specific time, but the last buy was on 25th april…. assuming that they already saw 12 recurrences in total the other 2 can happen before october. so the best for him is not to buy, SEC takes very seriously this “insider trading” thing.

$GLSI The lock-up and structure is essentially this... ''If this fails, our management team go down with you'' You don't see that very often; normally it's the founders diluting, paying themselves absurd salaries and self-granted stock options - and if it fails they're fine; you as a retail investor are the one holding the bag.
