Background This Phase I study (VOLTAIRE™-PK) aimed to evaluate three-way pharmacokinetic similarity (bioequivalence), safety and immunogenicity of BI 695501 (a Humira® [adalimumab] biosimilar candidate) compared with US- and EU-approved Humira in healthy male subjects. Methods Subjects (N = 327) were randomized 1:1:1 to receive one 40 mg subcutaneous dose of BI 695501, US- or EU-approved Humira; safety was assessed for 70 days. Bioequivalence was evaluated using the average bioequivalence method to test if the 90% confidence intervals (CIs) of the geometric means (BI 695501 versus US- and EU-approved Humira) for the primary endpoints were within pre-specified acceptance ranges (80-125%)...

Biologics are increasingly being used to modify the course of immune-mediated inflammatory diseases. Some main agents are monoclonal antibodies and a fusion-protein that target TNF. This group includes adalimumab, infliximab, certolizumab pegol, golimumab and etanercept. Although the efficacy of anti-TNFs is supported by numerous randomized clinical trials, their pharmacokinetics depend on many factors, in particular immunogenicity, which can cause marked and rapid clearance and a consequent decrease in efficacy...

Prior to clinical studies, the pharmacokinetics (PK) of antibody-based therapeutics are characterized in preclinical species; however, those species can elicit immunogenic responses that can lead to an inaccurate estimation of PK parameters. Immunodeficient (SCID) transgenic hFcRn and C57BL/6 mice were used to characterize the PK of three antibodies that were previously shown to be immunogenic in mice and cynomolgus monkeys. Four mouse strains, Tg32 hFcRn SCID, Tg32 hFcRn, SCID and C57BL/6, were administered adalimumab (Humira®), mAbX and mAbX-YTE at 1 mg/kg, and in SCID strains there was no incidence of immunogenicity...

INTRODUCTION: Hidradenitis suppurativa/acne inversa (HS) is a chronic, inflammatory, recurrent, debilitating skin disease of the hair follicle that usually presents after puberty with painful, deep-seated, inflamed lesions in the apocrine gland-bearing areas of the body, most commonly the axillae, inguinal and anogenital regions. A mean disease incidence of 6.0 per 100,000 persons-years and a varying prevalence of 0.05-1% have been reported worldwide. AREAS COVERED: This manuscript summarizes the current evidence on chemistry, pharmacodynamics, pharmacokinetics, as well as clinical efficacy, safety and tolerability of the currently approved biologic drug adalimumab in the treatment of active moderate to severe HS in adults...

The development of antidrug antibodies (ADAs) is a common cause for the failure of biotherapeutic treatments and adverse hypersensitivity reactions. Here we demonstrate that poly(lactic-co-glycolic acid) (PLGA) nanoparticles carrying rapamycin, but not free rapamycin, are capable of inducing durable immunological tolerance to co-administered proteins that is characterized by the induction of tolerogenic dendritic cells, an increase in regulatory T cells, a reduction in B cell activation and germinal centre formation, and the inhibition of antigen-specific hypersensitivity reactions...

The clearance of therapeutic monoclonal antibodies (mAbs) typically does not involve cytochrome P450 (CYP450)-mediated metabolism or interaction with cell membrane transporters, therefore the pharmacokinetics interactions of mAbs and small molecule drugs are limited. However, a drug may affect the clearance of mAbs through the modulation of immune response (e.g., methotrexate reduces the clearance of infliximab, adalimumab, and golimumab, possibly due to methotrexate's inhibitory effect on the formation of antibodies against the mAbs)...

Dose selection is one of the key decisions made during drug development in pediatrics. There are regulatory initiatives that promote the use of model-based drug development in pediatrics. Pharmacometrics or quantitative clinical pharmacology enables development of models that can describe factors affecting pharmacokinetics and/or pharmacodynamics in pediatric patients. This manuscript describes some examples in which pharmacometric analysis was used to support approval and labeling in pediatrics. In particular, the role of pharmacokinetic (PK) comparison of pediatric PK to adults and utilization of dose/exposure-response analysis for dose selection are highlighted...

6-thioguanine nucleotides levels are associated with clinical remission in patients with inflammatory bowel disease (IBD) on thiopurine monotherapy. Recently, few studies investigated the interaction between thiopurine metabolism and anti-tumor necrosis factor therapy among patients with IBD on combotherapy. Two studies demonstrated that infliximab therapy increases 6-thioguanine nucleotides level, while such effect could not be observed with adalimumab. Three studies showed that a Delta mean corpuscular volume >7 and high 6-thioguanine nucleotides levels are associated with favorable outcomes, i...

Because IgG1 allotypes might have different half-lives, their influence on infliximab (G1m17,1 allotype) pharmacokinetics was investigated in a group of spondyloarthritis patients. Infliximab was found to have a shorter half-life in patients homozygous for the G1m17,1 allotypes than in those carrying the G1m3 with no G1m1 (G1m3,-1) allotype. Because the neonatal FcR (FcRn) is involved in the pharmacokinetics of mAbs, the interaction of different IgG1 allotypes with FcRn was examined using cellular assays and surface plasmon resonance...

The purpose of this study is to test the feasibility of neonatal immune tolerance induction in mice to enable long-term pharmacokinetic studies with immunogenic therapeutic monoclonal antibodies (mAb). Neonatal immune tolerance was induced by transfer of a mAb to neonatal mice via colostrum from nursing mother mice treated with two subcutaneous doses of a tolerogen starting within the first 24 h after delivery. Adalimumab and efalizumab were administered as tolerogens at various dose levels. Tolerance induction was evaluated in the offspring after reaching adulthood at 8 weeks of age...

Monoclonal antibodies (MAbs) exhibit complex pharmacokinetics (PK) and pharmacodynamics (PD, response) against tumor necrosis factor (TNF). Many factors impact anti-TNF MAb PK, altering MAb clearance and therefore the half-life: albumin, weight (particularly, obesity), disease (severity, stage and co-morbidities) and concomitant administration of immunosuppressants (e.g. methotrexate). These factors can alter MAb exposure, impacting on the likelihood of clinical response. Formation of anti-drug antibodies (ADAs) is another potential factor that can affect MAb PK...

BACKGROUND: Anti-tumour necrosis factor (anti-TNF) monoclonal antibodies have shown efficacy in inflammatory bowel diseases (IBD). As these therapies lose patent protection, biosimilar versions of the originator products are being developed, such as the infliximab biosimilar CT-P13; however, some uncertainty exists regarding their pharmacology in IBD. AIM: To review the literature on anti-TNF biosimilars focusing on pharmacokinetics, pharmacodynamic properties and comparative effectiveness, related to their use in IBD...
