Tumor Necrosis Factor Inhibition in Focal Segmental Glomerulosclerosis and Treatment Resistant Minimal Change Disease

University of Michigan

Status and phase: Completed; Phase 2

Conditions: Minimal Change Disease; FSGS; MCD; Focal Segmental Glomerulosclerosis

Treatments: Drug: adalimumab

Study type: Interventional

Funder types: Other

Identifiers

NCT04009668

HUM00147018

Details and patient eligibility

About

The researchers are testing adalimumab, a treatment which blocks tumor necrosis factor (TNF), to see if it changes levels of urine biomarker levels (TIMP1 and MCP1). The outcomes may help develop individualized treatment options for future patients with TNF driven Focal segmental glomerulosclerosis (FSGS) or minimal change disease (MCD).

Enrollment: 7 patients

Sex: All

Ages: 6 to 80 years old

Volunteers: No Healthy Volunteers
