SB5: An Adalimumab Biosimilar

Abstract

SB5 (Imraldi^®) is a biosimilar of the reference anti-TNF monoclonal antibody adalimumab. It is approved for use in the following indications for which reference adalimumab is approved: rheumatoid arthritis (RA), juvenile idiopathic arthritis [polyarticular juvenile idiopathic arthritis (pJIA) and enthesitis-related arthritis (ERA)], axial spondyloarthritis [ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-axSpA)], psoriatic arthritis (PsA), psoriasis, pediatric plaque psoriasis, hidradenitis suppurativa (HS), Crohn’s disease, pediatric Crohn’s disease, ulcerative colitis (UC), and non-infectious uveitis. SB5 has similar physicochemical and pharmacodynamic properties to those of reference adalimumab, and the pharmacokinetic similarity of these agents has been shown in healthy volunteers and patients with RA. SB5 demonstrated clinical efficacy considered equivalent to that of reference adalimumab in patients with RA, and was generally well tolerated in this population. The safety and tolerability profile of SB5 was similar to that of reference adalimumab, as was the immunogenicity profile. Switching from reference adalimumab to SB5 had no impact in terms of efficacy, safety or immunogenicity. The role of reference adalimumab in the management of RA, pJIA, ERA, AS, nr-axSpA, PsA, psoriasis, pediatric plaque psoriasis, HS, Crohn’s disease, UC and non-infectious uveitis is well established and SB5 provides an effective biosimilar alternative for patients requiring adalimumab therapy.
