New treatment option for Rheumatoid Arthritis
Official title Study of LFD-200 in Healthy Adults and Adults With Moderate to Severe Rheumatoid Arthritis
ClinicalTrials.gov ID: NCT07207954
What this study is testing
What is LFD-200?
LFD-200 is an investigational medicine, given as an once-weekly injection under the skin, being studied as a potential treatment for rheumatoid arthritis.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This is a double-blind, randomized, placebo- and active-controlled study investigating the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of subcutaneous (SC) doses of LFD-200. The study design includes: a single ascending dose (SAD) study in up to 66 adult healthy participants (HPs) to investigate the effects of a single SC dose, with a 30-day follow-up; a multiple ascending dose (MAD) study in up to 40 HPs to assess up to 4 weekly SC doses, with a 30-day follow-up after the last dose; and a MAD study in up to 70 participants with moderate to severe rheumatoid arthritis (RA) to evaluate up to 13 weekly SC doses, with a 30-day follow-up after the last dose.
- Phase 1: an early, usually small safety study
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
