  • Title: Safety profile of biological therapies for treating rheumatoid arthritis.
    Author: Cañete JD, Hernández MV, Sanmartí R.
    Journal: Expert Opin Biol Ther; 2017 Sep; 17(9):1089-1103. PubMed ID: 28657381.
    Abstract:
    Biological agents such as tumor necrosis factor inhibitors (TNFi), abatacept, rituximab and tocilizumab have proven efficacy in RA. However, these agents are also associated with adverse events so further data is essential to detect them at the earliest stage possible. Areas covered: Herein, the authors review the safety profile of biological therapy, including TNFi and non-TNF agents including abatacept (ABA), rituximab (RTX) and tocilizumab (TCZ). The authors analyze both published articles and congress communications including clinical trials, meta-analyses, observational studies, data from registries and spontaneous clinical reports. The authors classify studies according to the most common and relevant adverse events associated with biological agents. Expert opinion: Biological therapies have a reasonable safety profile and, globally, the benefits far outweigh the possible risk of adverse events. Currently, the risk of serious infections is low and no increased risk in solid malignancies or cardiovascular events have been found after a long clinical experience with these therapies. However, there are still potential risks as well as concerns of immunogenicity induced by TNFi. More studies are required to understand these risks, design safer drugs, and implement pharmacogenomics into the clinic. This will lead to a more personalized medicine in the future.
