Early effects of ozoralizumab 30 mg in patients with rheumatoid arthritis and inadequate response to methotrexate: a post hoc trajectory analysis of the phase II/III OHZORA trial. (PubMed, RMD Open) - "OZR 30 mg demonstrated both immediate and sustained efficacy in MTX-IR patients with RA. Multivariate analysis suggested that both baseline inflammation and disease activity-represented by CRP and CDAI-may independently influence treatment response. However, residual confounding due to baseline disease activity cannot be completely excluded, and this remains a limitation of the present study."

EFFECTIVENESS OF CYTOTOXIC T-LYMPHOCYTE ANTIGEN-4-Ig AND JANUS KINASE INHIBITOR IN RHEUMATOID ARTHRITIS PATIENTS WITH HIGH RHEUMATOID FACTOR LEVELS: A RETROSPECTIVE COMPARATIVE STUDY IN SINGLE CENTER (EULAR 2025) - "Among the TNFi group, 31 TCs involved Fc-free agents (certolizumab pegol and Ozoralizumab). In high RF levels group, CTL-4-Ig was highest retention rate, while TNFi and aIL-6R showed lower retention rates. JAKi retention was comparable to CTLA-4-Ig and was less influenced by RF levels, supporting its use as a second-line option for high RF patients. Based on our results of the survival analysis, it will be necessary to consider comparing disease activity to further investigate the effectiveness of treatments based on RF levels."

Spacing of a TNF blocker and dose reduction of methotrexate in patients with rheumatoid arthritis in remission or low disease activity with ozoralizumab and methotrexate: a randomised, controlled trial (SORAIRO trial) (EULAR 2025) - "In patients who have achieved remission with a combination of TNF inhibitor and MTX therapy, extending OZR interval or reducing MTX dose can be feasible and favorable under careful clinical monitoring. This study also re-emphasises the importance of achieving remission for the subsequent successful treatment reduction."

Efficacy of ozoralizumab based on baseline RF titres in patients with RA: A post hoc analysis of the OHZORA trial (EULAR 2025) - "The Phase II/III OHZORA trial evaluated the efficacy and safety of OZR at 30 or 80 mg for 52 weeks in patients with active rheumatoid arthritis (RA) despite methotrexate therapy [2, 3]. Generally, the efficacy of anti-TNF antibodies containing the fragment crystallizable (Fc) portion is reduced in patients with high titres of rheumatoid factor (RF) [4, 5]; on the other hand, certolizumab pegol (CZP) that lacks the Fc portion is effective regardless of RF titres [6, 7]... OZR is an effective anti-TNF treatment for RA, regardless of RF and ACPA titres, and exhibits promise as a novel therapeutic option."

Development of a novel bacterial production system for recombinant bioactive proteins completely free from endotoxin contamination. (PubMed, PNAS Nexus) - "Moreover, we applied our system to produce ozoralizumab, a multispecific VHH that binds to human TNF-α and albumin and are marketed as a rheumatoid arthritis drug. We successfully purified a functional antibody from endotoxin contamination. This system establishes a new, completely endotoxin-free platform for the expression of recombinant proteins, which distinguishes it from other bacterial expression systems, and holds promise for future applications."

A pivotal decade for bispecific antibodies? (PubMed, MAbs) - "Nevertheless, only three bsAbs (catumaxomab, blinatumomab, emicizumab) were approved through the end of 2020. However, since then, 11 bsAbs received regulatory agency approvals, of which nine (amivantamab, tebentafusp, mosunetuzumab, cadonilimab, teclistamab, glofitamab, epcoritamab, talquetamab, elranatamab) were approved for the treatment of cancer and two (faricimab, ozoralizumab) in non-oncology indications. Notably, of the 13 currently approved bsAbs, two, emicizumab and faricimab, have achieved blockbuster status, showing the promise of this novel class of therapeutics. In the 2020s, the approval of additional bsAbs can be expected in hematological malignancies, solid tumors and non-oncology indications, establishing bsAbs as essential part of the therapeutic armamentarium."

Pharmacological profiles and clinical efficacy of ozoralizumab (Nanozora 30 ‍mg Syringes for S.C. Injection), the first Nanobody compound in Japan (PubMed, Nihon Yakurigaku Zasshi) - "Ozoralizumab showed an inhibitory effect on TNFα-induced cell death, and its inhibitory concentration was lower than that of etanercept, adalimumab, and infliximab...In clinical trials, ozoralizumab demonstrated clinical efficacy in rheumatoid arthritis patients with inadequate response to methotrexate, which was observed from day 3 of treatment...Based on these results, ozoralizumab was approved in September 2022. Ozoralizumab shows early improvement of clinical symptoms in patients with rheumatoid arthritis, and its characteristic structure is expected to be new treatment options for patients who have an inadequate response to current bDMARDs."

Population pharmacokinetics of ozoralizumab in patients with rheumatoid arthritis. (PubMed, J Clin Pharmacol) - "Body weight, sex, anti-drug antibody status, estimated glomerular filtration rate, and concomitant methotrexate use were identified as covariates for CL/F, while body weight and sex were covariates for V /F in the final model. When administered at 30 mg every 4 weeks, the predicted steady-state plasma trough concentration in a patient weighing 83.2 kg exceeded the trough concentration required to maintain efficacy of ozoralizumab, and the estimated exposure in a patient weighing 42.5 kg did not exceed the mean exposure at 80 mg, a well-tolerated dose, throughout 52 weeks. We developed a population PK model that adequately described the ozoralizumab PK in Japanese patients with RA, and none of the evaluated covariates showed clinically relevant effects on the PK of ozoralizumab."
