About AP1189

The mechanism of action of SynAct Pharma ́s lead compound AP1189 is to promote resolution of inflammation through melanocortin receptor activation directly on macrophages, thereby reducing the pro-inflammatory activity of macrophages and by stimulating macrophage efferocytosis, a specific ability to clear inflammatory cells (J Immun 2015, 194:3381-3388). This effect has shown to be effective in disease models of inflammatory and autoimmune diseases and the clinical potential of the approach is currently tested in three clinical phase 2a studies in patients with active rheumatoid Arthritis, nephrotic syndrome and COVID-19 associated respiratory distress.

The study population consist of newly diagnosed subjects with severly active RA (Clinical disease activity score, CDAI >22) who are candidates for methotrexate (MTX) treatment.

The first part of the study that now has been completed consisted of two cohorts. In the first cohort a total of 14 patients were treated with 50 mg AP1189 or placebo oral dosing once daily for 4 weeks as add on treatment to MTX naïve patients.

In the second part of the study that was initiated in the week of November 9, 2020, 50 mg AP1189, 100 mg AP1189 or placebo given orally in a 1:1:1 randomization will be dosed once daily for 4 weeks as add on to MTX as in part 1 of the study. The study is being conducted at sites in Denmark, Sweden, Norway, Bulgaria and Moldova.
