Pharmacokinetics, Safety, and Immunogenicity of Intravenous and Subcutaneous Single-Dose QX002N Injection in Healthy Subjects: A Randomized, Open, Parallel, Single-Center, Phase I Study. (PubMed, Rheumatol Ther) - "Immunogenicity was assessed and all the subjects in this study were Anti-drug antibody (ADA)-negative, which means no subjects appeared to develop immunogenicity to QX002N. All the results testify to the safety of QX002N injection, which is satisfactory after IV or SC dosing in healthy subjects."
