Repeated administration of infliximab (5 mg/kg at 0, 2 and 6 weeks in fistulising Crohn's disease, 3 or 10 mg/kg every 4 or 8 weeks in rheumatoid arthritis) resulted in a slight accumulation of infliximab in serum after the second dose. No further clinically relevant accumulation was observed.

Infliximab (Remicade, Renflexis, Inflectra) is a chimeric immunoglobulin (IgG1 kappa) targeting tumor necrosis factor-alpha (TNF-a), and it is currently FDA-approved for the treatment of multiple inflammatory conditions. Serum infliximab levels were measured using an enzyme-linked immunosorbent assay as previously described (8). The lowest level of infliximab that could be reliably detected was 0.1 g/ml. Modeling the serum profiles of infliximab.

Serum infliximab

Infliximab, a chimeric monoclonal antibody, is used to treat rheumatoid arthritis, psoriatic arthritis, Crohn’s disease, and other autoimmune diseases. Clinical responses are different among patients due to inadequate amount of drug circulating in the blood. Optimizing infliximab (IFX) treatment in pediatric patients with inflammatory bowel disease (IBD) by using serum infliximab (S-IFX) trough levels and antibodies to IFX is recommended. There is need for studies assessing this strategy in clinical practice. Infliximab is a chimeric IgG1 monoclonal anti-tumor necrosis factor (TNF) antibody and is administered as an intravenous infusion with weight-based dosing (5 mg/kg) and a regimen that includes an induction phase (intravenously at weeks 0, 2, and 6) followed by maintenance treatment (intravenously every 8 weeks) in responder patients. 3 The purpose of testing serum antibodies and serum levels (trough levels) to infliximab (Remicade), adalimumab (Humira), vedolizumab (Entyvio), or ustekinumab (Stelara) in patients with arthritis (e.g., rheumatoid, psoriatic, or juvenile idiopathic), inflammatory bowel disease (IBD), ankylosing spondylitis, or plaque psoriasis is to improve health outcomes. Conclusion Infliximab is associated with attenuated immunogenicity to a single dose of the BNT162b2 and ChAdOx1 nCoV-19 SARS-CoV-2 vaccines.

Low infliximab serum trough levels and anti-infliximab antibodies are prevalent in rheumatoid arthritis patients treated with infliximab in daily clinical practice: results of an observational cohort study. BMC Musculoskelet Disord 2012; 13: 184., 26 Ben-Horin S, Yavzori M, Katz L, et al.

Early serum infliximab trough level, clinical disease activity and CRP as markers of sustained benefit of infliximab treatment in Crohn’s disease: a post-hoc analysis of the ACCENT1 trial . Am J Gastroenterol 2011;106:S462 – 3. Measurement of antibodies to infliximab or adalimumab in a patient receiving treatment with infliximab or adalimumab, either alone or as a combination test that includes the measurement of serum infliximab levels or serum adalimumab levels is not covered as the evidence is insufficient to determine the effects of the technology on health outcomes.

There is a significant difference between serum infliximab levels in patients with IBD in remission, compared with those who relapse. A trough threshold during maintenance > 2 µg/ml is associated with a greater probability of clinical remission and mucosal healing. Infliximab, trough, remission, mucosal healing The serum concentration of infliximab obtained 1 hour after infusion approximates the C max for infliximab. At week 0, the median serum concentrations of the 1 hour–postinfusion samples were 68.6 μg/ml and 219.1 μg/ml for subjects receiving 3 mg/kg and 10 mg/kg infliximab, respectively, every 8 weeks (Table 1).
