I picked this up from Twitter - Myositis Support in the USA and Idera are hosting a video chat session about a Phase 2 trial for Idera's drug IMO-8400 for treatment of DM.
Oooh, this was a little while ago now, but thanks for asking.
I did attend this webinar - I think I was the only one from the UK, everyone else was from the USA. It was a really small group, maybe around 5 people with DM (one from the US Myositis Association) plus representatives from Idera. From what I recall, the drug was designed primarily to deal with severe skin symptoms in DM.
A couple of the research scientists explained a bit about how the theory behind how the drug worked and took us through the plans for the phase 2 trials - eligibility, funding, trial centres, protocols etc. I wouldn't have been eligible for the trial on medical grounds, but also, there was no UK trial centre. So though interesting, all this was purely theoretical for me, and I heard nothing more.
I've done some Googling, and found this report from the US Myositis Association:
