Phase 1a/b Tolerability of NTR-1011 in Healthy Adults and Adult Patients With SLE and RA

This phase 1a and 1b study is designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, immunogenicity, and preliminary efficacy of NTR-1011 in healthy adults and in adult patients with systemic lupus erythematosus and rheumatoid arthritis. The main goals of this study are to determine the safety profile of NTR-1011 across subcutaneous and intravenous dose levels, understand how the drug behaves in the body, characterize its biological activity through relevant pharmacodynamic markers, assess the potential for immune responses to treatment, and explore early signals of clinical benefit in autoimmune disease settings. This is a randomized, double blind, placebo controlled study that begins with a single ascending dose evaluation in healthy volunteers followed by a multiple dose assessment in patients. The design is intended to define the highest safe and well tolerated dose, establish a robust PK and PD baseline, and generate initial patient level evidence to support dose selection and advancement into subsequent clinical development.
