Trial Summary

What is the purpose of this trial?

The purpose of the study is to assess the concentration of rozanolixizumab in mature breast milk of healthy study participants following administration of a single dose of rozanolixizumab

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are taking biologic agents (like monoclonal antibodies), you must not have used them within 3 months or 5 half-lives before the study.

What makes the drug Rozanolixizumab unique compared to other treatments?

Rozanolixizumab is unique because it is a monoclonal antibody designed to target and reduce the activity of specific immune system components, potentially offering a novel approach for conditions where traditional treatments may not be effective.12345

Findings from Research

Tocilizumab, a humanized monoclonal antibody targeting sIL-6R, shows promise as a treatment for rheumatoid arthritis, with safety data from randomized controlled trials indicating no increased risk of opportunistic infections or cancers.
However, there are concerns about elevated liver function tests and altered lipid profiles, which need to be further investigated in larger studies with longer follow-up to understand their significance.
Interleukin-6 inhibition--tolerability profile and clinical implications.Strand, V., Yazici, Y.[2016]
A 72-year-old woman developed severe anterior uveitis after receiving tocilizumab infusions for rheumatoid arthritis, suggesting a potential adverse effect of this anti-IL-6 receptor therapy.
The patient's ocular inflammation was successfully managed with corticosteroids, indicating that while tocilizumab can effectively treat rheumatoid arthritis, it may also lead to serious eye complications like uveitis after treatment cessation.
Acute anterior uveitis after discontinuation of tocilizumab in a patient with rheumatoid arthritis.Sato, T., Minakuchi, S., Mochizuki, M., et al.[2021]
Tocilizumab, an anti-IL-6 receptor monoclonal antibody, effectively blocks IL-6 receptors and normalizes C-reactive protein levels in patients with rheumatoid arthritis and systemic juvenile idiopathic arthritis, with biweekly doses of 8 mg/kg for patients ≥ 30 kg and 12 mg/kg for those < 30 kg.
The pharmacokinetic parameters, including serum concentrations and area under the curve, were similar across both dosing groups, indicating consistent efficacy and safety in achieving clinical endpoints regardless of the dose.
