Is this trial a fit for you?

Likely a good fit

Adults with active seropositive autoimmune disease (e.g., Sjögren’s disease or IIM) who have relapsed or are refractory after at least two prior/ongoing treatments and weigh at least 50 kg.

Probably not a fit

Potential participants who do not experience a favorable safety/tolerability profile or who do not show exploratory efficacy signals may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is an open-label, multicenter, Phase 1 trial evaluating safety, tolerability, and pharmacokinetics of OM336 in adults with seropositive autoimmune diseases such as Sjögren’s disease and idiopathic inflammatory myopathy. Participants receive ascending doses of OM336 subcutaneously, with ongoing monitoring for adverse events and immune responses. Exploratory assessments will look at clinical signals of response and biomarker changes to guide future research. The study helps establish initial safety data and PK/ADA profiles in this patient population.

Why it matters

Potential benefit: If successful, participants may experience direct safety-related benefits and contribute to understanding how OM336 behaves in the body, potentially guiding future therapies.

How similar studies have gone: Other early-phase biologics in seropositive autoimmune diseases have shown safety signals in similar designs, but this specific agent and population are exploratory.
