2016;5(2):70-3.DOI: 10.5639/gabij.2016.0502.018, Author byline as per print journal: Professor Paul J Declerck, PhD; Paul W Tebbey, PhD. Submitted: 5 May 2016; Revised: 23 June 2016; Accepted: 24 June 2016; Published online first: 7 July 2016.

Biological therapeutics are highly sensitive to formation of structural variants during manufacturing processes. Nevertheless, presence of anti-adalimumab antibodies, even at moderate concentration, can impact patients’ response to treatment. Pattie | Tebbey PW, Varga A, Naill M, Clewell J, Venema J. 2014;6(5):1145-54. If you have any further questions or concerns after reading this leaflet, please speak to your doctor or the nurses at the Rheumatology, Dermatology or Gastroenterology Departments. 6. Additionally, a high degree of consistency for the sum of lysine variants was observed between five different bioreactor sizes used for production [6]. You may be aware that the patent for Humira has expired and several biosimilars have been approved and are available to patients.

In studies of rheumatoid arthritis and Crohn’s disease, anti-adalimumab antibodies were associated with lower adalimumab serum levels [16, 17]. Biosimilars are regulated in a similar way to the original licensed product. 1997;159(4):1728-38. Biosimilars have a similar safety profile to the original biologics. B-cell depletion in vitro and in vivo with an afucosylated anti-CD19 antibody. 11. Since the Adalimumab biosimilar offers cost savings and enables us to deliver care more effectively, we aim to gradually switch all patients currently using Humira over to the new Adalimumab biosimilar.

These structural variants can affect clinical performance. BioDrugs. Brady LJ, Velayudhan J, Visone DB, et al. 2010;335(1):213-22. Generics and Biosimilars Initiative (GaBI), As is the case for many biologicals, adalimumab is a large glycoprotein that is a heterogenous mixture of structural isoforms [, Differences in glycosylation profile and cleavage of C-terminal lysines can affect the tertiary (i.e. The process for manufacturing Humira, the original Adalimumab, has itself altered several times since it was first introduced resulting in a cleaner drug with fewer side effects. interaction of protein subunits) of a biological agent [, A recent product quality analysis evaluated 544 total batches of adalimumab manufactured between 2000 and 2013 [, It has been clearly demonstrated that the manufacturing process for adalimumab produced a consistent product over an extended (> 10 years) period of time [, Variations in glycosylation pattern or other post-translational modifications can result in subtle changes in the conformation of a biological that can potentially alter its solubility, stability, efficacy, or immunogenicity [, Immunogenicity is a primary area of safety for biologicals and is often carefully monitored [, The presence of anti-adalimumab antibodies after treatment varied between 3% and 28% among different disease states, see, Changes to a tightly controlled manufacturing process that may lead to variations in epitopes could disrupt the immunologically tolerated state of a patient to their initial therapeutic.

Non-neutralizing antibodies bind biological molecules on sites unrelated to target binding; however, non-neutralizing antibodies can reduce drug bioavailability through increased clearance, indirectly decreasing efficacy [14]. A risk-based bioanalytical strategy for the assessment of antibody immune responses against biological drugs. 2015;10(8):e0134949. 25. 2014;28(4):363-72. The advent of biosimilars increases the need to understand the clinical impact of potential differences versus originator products.
