A Study of Single and Multiple Ascending Doses of VIB1116 in Rheumatic Diseases

A Phase 1, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Safety, Pharmacokinetics and Pharmacodynamics of Single and Multiple Ascending Doses of VIB1116 in Conventional Dendritic Cell (cDC) and Plasmacytoid Dendritic Cell (pDC)-Mediated Rheumatic Diseases

A first-in-human study to evaluate the safety and tolerability of escalating, single and multiple ascending doses of VIB1116 in adult participants with rheumatic diseases.

Study acquired from Horizon in 2024. Originally Viela Bio was the sponsor.
