My response in the MDGL forum was in response to an post from Biotech_Jim from 2017.
There is no statement that they are presenting this year, but as late-breaking abstract submissions closed on 15-September it seems that this is a possibility.
I don't know how the late-breaking abstracts are fitted into the schedule as there are no obvious open slots - though there are two slots with no details:
Hepatitis C Poster Session
Date: Friday, November 12th
Time: 6:00 - 11:55 AM EST
Inflammation and Immunobiology: Animal Models; Adaptive Immunity; Mechanisms of Injury; QO1, QO3, Q
Date: Friday, November 12th
Time: 6:00 - 11:55 AM ESTO4
