A Phase 1 Study of FT819 in B-cell Mediated Autoimmune Disease

Study Purpose

This is a phase 1 study designed to evaluate the safety, pharmacokinetics (PK), and anti-B-cell activity of FT819 following treatment with or without auxiliary medicinal product (AMP) in participants with moderate to severe active systemic lupus erythematosus (SLE), antineutrophilic cytoplasmic antibody (ANCA)-associated vasculitis (AAV), idiopathic inflammatory myositis (IIM), and systemic sclerosis (SSc). The study will consist of a dose-escalation stage, followed by an expansion stage to further evaluate the safety and activity of FT819.

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT06308978
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
