RE: The price of Sotyktu (deucravacitinib) treatment23 Mar 2024 11:34
There is no reason why SAR20347 cannot out perform Deucravacitinib.
'20347
. Both Tyk2 mutant mice and mice treated with SAR-20347 showed significant reduction of IL-6 and IL-17 in imiquimod-induced skin lesions, but only SAR-20347-treated mice presented reduced levels of IL-23, decreased keratinocyte proliferation and improved clinical score [22]. In addition, SAR-20347-treated mice manifested lower IL-17 gene expression compared to Tyk2 mutant mice [22]. In this model, Works et al. demonstrated that SAR-20347 treated mice showed an almost complete loss of IL-22 gene expression in skin lesions, and they postulate that SAR-20347 would impair the ability of Th17 and γδ cells to induce IL-22 [22]. IL-22 is required for development of autoreactive Th17 cells [77,78]. However, not only IL-22 production was impaired, since IL-22 signaling was also affected in vitro in a human colonic cell line, and STAT3 phosphorylation dependent of IL-22 was completely blocked [22].'
In addition
'Blocking both Tyk2 and Jak1 in this study was more effective than inhibition of Tyk2 alone at reducing psoriasis-like disease severity, keratinocyte proliferation, as well as IL-23, IL-17, IL-6, IL-22, and antimicrobial peptide gene expression, and the authors postulate that targeting a combination of Jak1 and Tyk2 using an orally available inhibitor may be a viable approach for treating psoriasis, but currently there are no ongoing or completed clinical trials for SAR-20347 [22].'
There are trials ongoing now! The above report from early 2023.
Now those that bother to read my posts will know the importance l believe in Jak pairing.
Jak1 and Jak2 in particular
The all important interleukin 10.
4 subunits of IL-10
2 of which are Jak1 and 2 of which are Tyk2.
Deucravacitinib the allosteric inhibitor does not interact with either Jak1 or Jak2 in the human body.
20347 is not an allosteric inhibitor.
