CP 690550 is a specific inhibitor of JAK POWERFUL Hige which was originally identified as a blocker, but also inhibits JAK1 and JAK3 JAK2.60 CP 690,550 is very effective in animal models of arthritis.61 The compound has been studied in several trials Phase II RA with clear evidence of effectiveness.
In a randomized, double-blind, controlled Placebo-controlled, 6-month study improvements dose after 1 week ACR20 already been observed after starting treatment.62 63 For 6 weeks, 81% of 70 patients achieved AB1010 ACR20 drug, compared with 29% in the placebo group. about a quarter of the patients met ACR70 criteria compared to 3% in the placebo group. Headache, dizziness and nausea are the hours Common side effects. Dose–Dependent side effects such as serum creatinine, high cholesterol, and neutropenia at Mie were also observed. Some of them are almost certainly based mechanism because JAK involved colony stimulating factor and ??rythropo Retina signalling.60 spleen tyrosine kinase Syk kinase is a receptor protein tyrosine not prime R expressed in bone marrow cells as well as from synoviocytes and vascular Endothelial cells.

Subsequently End activates Syk regulate different ways, inflammation, including normal MAPK, phosphoinositide 3-kinase and phospholipase C ?. Can activate pro-inflammatory cytokines such as TNF and IL-1 and Syk in synoviocytes, leading to JNK activation and expression of MMP IL6.68 69 and R788, R406 tion of a prodrug inhibits inflammatory cytokines and atomizer Proin arthritis arthritis in animal models. 70 Fostamatinib was recently evaluated in a randomized, controlled The placebo phase II study in RA patients who were resistant to MTX.
Clinical improvement as early as 1 week was observed after the start of treatment.71 12 weeks, approximately 72% of patients in the high dose group achieved at least an ACR 20 response at 38% in the placebo group. ACR70 response at 19% of the patients with the pretty highest dose were treated, compared to 4% in the placebo group. CRP levels rapidly and remained suppressed serum MMP3 and IL6 have been removed also. The h Most common adverse events were diarrhea, hypertension and neutropenia.
