Key clinical point: The biosimilar AVT02 is as efficacious, safe, and immunogenic as its originator, adalimumab, in moderate-to-severe chronic plaque psoriasis.
Major finding: At week 16, AVT02 and originator adalimumab induced comparable percentage improvement in Psoriasis Area Severity Index (91.6% and 89.6%, respectively), with the difference in percentage improvement within the predefined equivalence margins of ±10% (90% CI, −0.76 to 5.29), along with similar safety, tolerability, and immunogenicity profiles, which lasted through week 50.
Study details: This was a phase 3 study including 413 adult patients with moderate-to-severe chronic plaque psoriasis who were initially assigned to receive AVT02 or adalimumab; at week 16, the latter were randomly reassigned to continue receiving adalimumab or switch to AVT02 until week 48.
