Effects of Telitacicept vs Cyclophosphamide on Lupus Related Interstitial Lung Disease
Trial Parameters
Brief Summary
Recent data indicate that Telitacicept is beneficial for lupus nephritis. Our goal is to determine whether Telitacicept is an effective and safe treatment, compared to standard-of-care Cyclophosphamide, for subclinical and clinical ILD in patients with early lupus.
