This proposal is to contribute to data registry and sample bank called Pediatrics Biorepository for Gastroenterology Clinical Research. Samples collected in this study may be used for future research which plan to advance the state of science in the hopes to develop novel diagnostic approaches and identify therapeutic targets.

The purpose of this study is to determine if the investigational (not FDA approved) drug VIB4920 can be an effective treatment for patients with active Lupus Nephritis (LN).

This study will compare treatment with MMF (mycophenolate mofetil), Prednisone, plus the study medication VIB4920 to treatment with MMF and Prednisone alone.

Participants will have 16 scheduled visits that will involve routine monitoring of disease activity, up to two kidney biopsies, and blood and urine specimen collections. Participation in this study will last approximately 1 year and 2 months. Compensation is available for participation.

Genetic changes to human skin contribute to a wide variety of conditions and diseases that affect over 20% of the population. However, the genes and molecules that are responsible for human skin development and disease are not fully understood, preventing the development of treatment options. This proposal seeks to better understand one disease in particular, linear morphea, a form of Sclerederma that can affect the skin, muscle, and bone. This study will recruit subjects to collect and use skin tissue for the purpose of identifying the genetic causes of linear morphea.
