2025 AAD Oral Report | Results of Phase III Study of Domestic JAK1 Inhibitor ivarmacitinib Sulfate Tablets in the Treatment of Severe Alopecia Areata in Adults Released [Google translation] (Jiangsu Hengrui Press Release) - P3 | N=330 | NCT05470413 | Sponsor: Reistone Biopharma Company Limited | "In the core phase of treatment, the trial group was treated with 4 mg/8 mg of amacitinib sulfate tablets, and the placebo group was treated with placebo. Amacitinib sulfate tablets were used for maintenance treatment from 24 weeks to 52 weeks. The primary endpoint of the study was to evaluate the proportion of patients with a SALT score ≤20 (indicating scalp hair loss ≤20%) at 24 weeks....The results of the primary endpoint of the study showed that at week 24, the proportions of patients with SALT scores ≤ 20 in the 4 mg/8 mg amacitinib sulfate group and the placebo group were 34.9%, 40.6%, and 9%, respectively. Compared with the placebo group, the differences in response rates in the 4 mg group and the 8 mg group were 25.6% (95% CI: 15.4-35.7, bilateral p<0.0001) and 31.6% (95% CI: 21.5-41.8, bilateral p<0.0001), respectively."

After that, patients in the placebo group then were randomly assigned in a 1:1 ratio to receive either dose of ivarmacitinib through week 52...According to the results, the primary endpoint occurred in 34.9% of patients in the 4 mg group, 40.6% in the 8 mg group and 9% in the placebo group. The difference in response rate was 25.6% (95% CI, 15.4%-35.7%) for the 4 mg group vs. placebo and 31.6% (95% CI, 21.5%-41.8%) for the 8 mg group vs. placebo....Among patients who switched to ivarmacitinib from placebo, about 47% of those who received 4 mg and 63% who received 8 mg had a SALT score of 20 or less at week 52."

Butyrolactone I blocks the transition of acute kidney injury to chronic kidney disease in mice by targeting JAK1. (PubMed, MedComm (2020)) - "Notably, BLI showed greater blood urea nitrogen reduction and anti-inflammatory effects than telmisartan...Furthermore, BLI demonstrated nephroprotective effects and safety comparable to ivarmacitinib, the well-known JAK1 inhibitor. Mechanistically, BLI targets JAK1 and inhibits its phosphorylation and JAK-STAT activation, subsequently regulating the downstream signaling pathways to inhibit reactive oxygen species production, inflammation, and ferroptosis, thereby preventing the occurrence of kidney fibrosis and blocking the AKI-CKD transition process. This study demonstrates for the first time that BLI is a JAK1 inhibitor and a promising candidate for delaying CKD progression, which warrants further investigation."
