So I received a response from Dr Carol Van Hulle to my question I asked her about results not being positive since we haven’t heard much. Here is what she said
“Preliminary results are like a first draft. As a rule, I do not share results outside of formal conferences until my work is peer reviewed and published. Much can change between preliminary results and final results. I will make a note to let you know when the final results are posted at ClinicalTrials.gov.
