RE: Tyk2 and IL-68 Jul 2021 09:54
C79 – thanks for the link. It’s a really interesting read and adds to what I was reading last night:
https://www.embopress.org/doi/full/10.15252/embj.201488856
To some extent it means that a lot of immunosuppressant therapeutics will need to handled very carefully and achieving the balance won’t be simply a case of ‘pop this pill and you’ll be fine’. Timing, dosage and ‘in combination with’ are all going to be key elements. What I hadn’t fully realised was the connection between IL-6 and depression in all its forms. What I have noticed over the last decade is the increase in anxiety based disorders and as referred to in the article, the lack of progress made in the therapeutics arena for psychiatric drugs. Long Covid has been associated with depression and anxiety but often diagnosed as due to the stress of being locked down or a persistent tail to the virus often tied in with ongoing (post viral) fatigue. From both articles it would appear that IL-6 is a contributor to both depression and some long Covid symptoms. Only this week there was a headline about ‘heart drug cures long Covid in hours’. Turns out that one patient had responded. Hardly a clinical trial. From my limited understanding the treatment of both depression and long Covid is highly unlikely to be cured in hours. However, as Thoth has previously surmised, the immune system may well be a culprit in a huge range of conditions. The full article (link posted by C79) mentions IL-6’s role in glucose regulation (ie diabetes) and also references sepsis. Should our TYK2 (1801) prove effective against Covid and something like RA then it does open up a completely new channel of opportunity. Interestingly the article referenced by SOG also mentions Dexamethasone as an IL-6 related therapeutic, a drug that we now know 1801 outperforms. Going into the Clinic for Covid will be an important step for 1801 but I’m also wondering if it means we should hang on to it until we have a better understanding of its full applicability. We certainly don’t want to give it away at a bargain price. On the other hand, I would far prefer it if it went on licence to a company that could speed it through trials and put it to good use against the likes of depression/diabetes/sepsis. It may be far more important than even the most optimistic ramper can see. However, as SOG says, if it doesn’t work then we may have nothing, or just a single indication drug, or just 1802 or just 737. Patience. GLA
