Hi friends, here's some good news: This month (June 2019) the Gates Foundation licensed a lot of further clinical testing of SPR720 for TB. http://www.tbonline.info/posts/2019/6/23/spero-therapeutics-announces-collaboration-bill-me.

SPR720 has also had demonstrated research success (in vitro and in vivo) with NTMs . It's been shown to be safe as well as clinically effective against MAC/MAI and Abscessus. https://sperotherapeutics.com/pipeline/spr720-non-tuberculosis-mycobacterium/.

So we might finally see some new drug action a lot faster than we would have if left to Big Pharma alone!
Hugs to all and all the best
