The U.S. Food and Drug Administration today approved a citrate-free, high-concentration formulation of adalimumab-bwwd (Hadlima), the manufacturer, Samsung Bioepis, and its commercialization partner Organon said in an announcement.
Hadlima is a biosimilar of the tumor necrosis factor inhibitor reference product adalimumab (Humira).
Hadlima was first approved in July 2019 in a citrated, 50-mg/mL formulation. The new citrate-free, 100-mg/mL version will be available in prefilled syringe and autoinjector options.

The 100-mg/mL formulation is indicated for the same seven conditions as its 50-mg/mL counterpart: rheumatoid arthritis, polyarticular juvenile idiopathic arthritis, plaque psoriasis, psoriatic arthritis, ankylosing spondylitis, adult and pediatric Crohn’s disease, and ulcerative colitis.
The approval was based on clinical data from a randomized, single-blind, two-arm, parallel group, single-dose study that compared the pharmacokinetics, safety, tolerability, and immunogenicity of the 100-mg/mL and 50-mg/mL formulations of Hadlima in healthy volunteers.
Both low- and high-concentration formulations of Humira are currently marketed in the United States. Organon said that it expects to market Hadlima in the United States on or after July 1, 2023, in accordance with a licensing agreement with AbbVie.
The prescribing information for Hadlima includes specific warnings and areas of concern. The drug should not be administered to individuals who are known to be hypersensitive to adalimumab. The drug may lower the ability of the immune system to fight infections and may increase risk of infections, including serious infections leading to hospitalization or death, such as tuberculosis, bacterial sepsis, invasive fungal infections (such as histoplasmosis), and infections attributable to other opportunistic pathogens.
A test for latent TB infection should be given before administration, and treatment of TB should begin before administration of Hadlima.
Patients taking Hadlima should not take a live vaccine.
The most common adverse effects (incidence > 10%) include infections (for example, upper respiratory infections, sinusitis), injection site reactions, headache, and rash.
