Upatinib (UPA) is an oral Janus kinase (JAK) inhibitor approved for the treatment of rheumatoid arthritis (RA)
.
JAK inhibitors are associated with an increased risk of herpes zoster (HZ) in RA patients
Rheumatoid arthritis
Recently, Annals of the Rheumatic Diseases, a top journal in the field of rheumatism, published a research article that aims to evaluate the incidence and risk factors of HZ in RA patients receiving UPA treatment from the UPA Phase III clinical trial project
.
In six randomized phase III trials (data cutoff date is June 30, 2020), researchers determined the HZ exposure adjustment rate/event rate of patients receiving UPA (monotherapy or combination therapy)
.
The incidence and event rate of HZ were also determined in patients receiving methotrexate (MTX) monotherapy or adalimumab (ADA) + MTX treatment
A total of 5306 patients were included in this analysis
.
The incidence of HZ in the MTX monotherapy group, ADA+MTX, 15mg UPA and 30mg UPA treatment groups was 0.
It can be seen that compared with ADA+MTX or MTX monotherapy , UPA has a higher incidence of HZ and event rate, and compared with a dose of 30mg and 15mg, the incidence of HZ and event rate is higher
.
Patients from Asia and a previous history of HZ may have an increased risk of HZ when receiving UPA treatment
Compared with ADA+MTX or MTX monotherapy, UPA has a higher incidence and event rate of HZ, and compared with a dose of 30mg and 15mg, the incidence of HZ and event rate is higher
