Herein we report identification of an imidazopyridine class of potent and selective TYK2 inhibitors, exemplified by prototype 6, through constraint of the rotatable amide bond connecting the pyridine and aryl rings of compound 1. Further optimization led to generation of compound 30 that potently inhibits the TYK2 enzyme and the IL-23 pathway in cells, exhibits selectivity against cellular JAK2 activity, and has good pharmacokinetic properties. In mice, compound 30 demonstrated dose-dependent reduction of IL-17 production in a PK/PD model as well as in an imiquimod-induced psoriasis model. In this efficacy model, the IL-17 decrease was accompanied by a reduction of ear thickness indicating the potential of TYK2 inhibition as a therapeutic approach for psoriasis patients.

Our study is also unique in reporting time-to clin. response. While clin. responses as defined in this anal. could only be achieved by patients who demonstrated defined clin. signs/symptoms at the start of PV-based therapy, the majority of those patients who achieved a clin. response and had a subsequent radiog. assessment also achieved a radiog. response, suggesting that clin. response, when detectable, may be an indicator of disease response in this patient population. In conclusion, patients with relapsed/refractory DLBCL/ HGBL treated at our center with PV, with or without concurrent rituximab and/or bendamustine, frequently achieved rapid and durable responses. These findings may inform clin. management as well as investigational study design for this patient population.
