For Patients with Autoimmune & Inflammatory Diseases
About Us
ValenzaBio is a privately-held biopharmaceutical company developing therapies for autoimmune and inflammatory diseases. With a pipeline of differentiated monoclonal antibodies targeting clinically-validated mechanisms of action, we seek to provide improved therapies for patients with limited treatment options. Based in Bethesda, Maryland, in the heart of the capital biotech community, we strive to work collaboratively with all stakeholders while keeping our research and development efforts focused on the needs of patients.
VB119
Program Overview
VB119 is an IgG1 monoclonal antibody with enhanced antibody-dependent cellular cytotoxicity (ADCC) and potent binding to CD19, a B-cell surface receptor found on autoantibody-secreting cells (ASCs). ASCs are closely linked to several autoimmune diseases, including membranous nephropathy (MN). Pathogenic ASCs often lack expression of CD20 and are not targeted by anti-CD20 antibodies, such as rituximab. Proof-of-mechanism for VB119 was established in a completed Phase 1 clinical trial, where peripheral B-cell depletion was observed in most patients after a single dose of VB119. VB119’s ability to bind and eliminate disease-causing ASCs that are not directly targeted by conventional therapies has the potential to provide clinical benefit for patients with MN, as well as other autoantibody-mediated diseases.
ValenzaBio is initiating an open-label Phase 1b/2a clinical trial of VB119 in primary MN patients with nephrotic-range proteinuria. This trial is a multi-center, open-label study to evaluate the safety, PK and efficacy of VB119. Key assessments include serum anti-PLA2R antibodies and proteinuria.

VB421
Program Overview
VB421 binds IGF-1R with sub-50 pM potency and no measurable effector function. IGF-1R signaling is implicated in several inflammatory and fibrotic diseases. In addition to high binding affinity, VB421 induces rapid and efficient receptor internalization that could potentially provide a differentiated mechanism-of-action relative to other anti-IGF-1R antibodies. IGF-1R overexpression and activation within orbital fibroblasts is thought to play a central role in the pathogenesis of Thyroid Eye Disease (TED). ValenzaBio believes VB421 has the potential to be a best-in-class therapeutic for TED. VB421 is currently in an IND-enabling program to support first-in-human studies for the treatment of TED and other autoimmune and fibrotic diseases.
