Should we take very early research work.
TYK2 was the first member of the JAK family to be isolated and essential for cellular responses to IL-6, -10, and -12 (Fig. 4B). Evidence suggests that target-specific inhibition of TYK2 may be a promising therapeutic strategy with an ideal safety-benefit balance for treating autoimmune disorders such as Crohn's disease, multiple sclerosis, and psoriasis. Interestingly, the distinctive catalytically inactive pseudokinase domain (JH2) has provided an ideal “allosteric” site for the discovery of a selective TYK2 small molecule inhibitor (Wrobleski et al., 2019). Bristol-Myers Squibb identified BMS-986165 as the first JH2-targeting allosteric TYK2 inhibitor candidate, which entered a phase III clinical trial for psoriasis (Moslin et al., 2019). In addition, BMS-986165 provided complete protection from colitis as determined by decreased weight loss and colonic histological scores (Burke et al., 2019).'
On the above hypothesis why has Deucravacitinib failed?
