CD40L Antagonism in Rheumatoid Arthritis (RA)

Stopped early · Phase 2 · Has a placebo group

Conditions studied: Rheumatoid Arthritis

In brief

The primary objective is to determine if the addition of a 12-week course of treatment with VIB4920 to TNFi treatment will result in improved clinical disease control in patients with RA who have had an inadequate response to a TNFi.

Prior history of a positive QuantiFERON-TB Gold, QuantiFERON-TB Gold Plus, T- SPOT.TB, or purified protein derivative (PPD) test without history of previous treatment for latent TB g. Symptoms of presumed or documented SARS-CoV-2 infection in the past 30 days h. More than one episode of herpes zoster in the past 12 months
