Impact of previous biologic use on the efficacy and safety of brodalumab and ustekinumab in patients with moderate-to-severe plaque psoriasis: integrated analysis of the randomized controlled trials AMAGINE-2 and AMAGINE-3

Abstract: The efficacy of brodalumab 210 mg Q2W was similar regardless of prior biological therapy (P = 0·31, 0·32 and 0·64 for PASI 75, 90 and 100, respectively). Almost twice as many patients achieved PASI 100 or complete clearance with brodalumab at week 12 compared with ustekinumab; the differences were most noticeable where previous biologics had failed. Both treatments were well tolerated.

“…PASI 75 responses of the reference arm in included studies were utilized to inform baseline event rates. Prior exposure to biological therapies varies across trials in psoriasis and is thought to be a potential effect modifier (20,21); therefore, a sensitivity analysis was carried out excluding studies which included <5% of patients with prior experience of biologics or which did not report this information.…”

“…The difference in PASI 100 response rates between Asian and non‐Asian patients may be due to random variability and the small proportions of patients who achieved a PASI 100 response. The results of previous studies with brodalumab and ustekinumab suggest that the higher proportion of patients with prior use of systemic and biologic agents in the Asian population may also play a role.…”
