Equillium Presents Clinical Data from EQUALISE Phase 1b Study in Lupus Patients at the American Society of Nephrology Annual Meeting


Equillium, Inc. (Nasdaq: EQ), a clinical-stage biotechnology company developing itolizumab to treat severe autoimmune and inflammatory disorders with high unmet medical need, today announced interim data from the Type A portion of the Phase 1b EQUALISE study that showed promising clinical activity in patients with systemic lupus erythematosus (SLE), and pharmacokinetic and pharmacodynamic data supporting the anti-CD6 mechanism of itolizumab. The data were presented in two separate posters, both by Chaim Putterman, M.D., Professor of Medicine, Albert Einstein College of Medicine, at the American Society of Nephrology annual meeting.

"These data provide additional insights into the promise of itolizumab as a potential therapy for patients with lupus," said Dr. Putterman. "I am especially intrigued by the decreases in proteinuria of up to 53 percent in patients with elevated baseline levels of proteinuria or albuminuria. I look forward to additional data generated in the ongoing EQUALISE study of itolizumab in the TYPE B cohort of patients with lupus nephritis."

In poster #1624, highlighting the exploratory subgroup analysis of SLE patients with elevated baseline levels of proteinuria or albuminuria, the data showed a decline in proteinuria of up to 53% following two doses of itolizumab. Proteinuria is used as a biomarker for potential kidney damage. Subcutaneous dosing of itolizumab was well tolerated with most adverse events being mild to moderate injection site reactions.

In a separate pharmacokinetic and pharmacodynamic poster (#1623), the data demonstrated dose-proportional increases in drug exposure and rapid and dose-dependent decreases of CD6 cell surface expression on CD4 cells in patients SLE.

"Itolizumab's mechanism of action selectively targeting the CD6-ALCAM signaling pathway to maintain a balanced immune response is translating well in patients," said Stephen Connelly, Ph.D., chief scientific officer of Equillium. "The dose dependent decrease in CD6 on T cells observed in the interim analysis of the EQUALISE study is encouraging and is consistent with the biomarker activity we've seen in other inflammatory indications where itolizumab is being studied."

About Systemic Lupus Erythematosus (SLE) / Lupus Nephritis (LN)

Systemic lupus erythematosus is an autoimmune disease in which the immune system attacks its own tissues, causing widespread inflammation and tissue damage in the affected organs. It can affect the joints, skin, brain, lungs, kidneys, and blood vessels. Lupus nephritis is a serious complication of SLE, occurring in approximately 30% ? 60% of individuals with SLE. In LN, the body's own immune system attacks the kidneys, causing inflammation and significantly reducing kidney function over time.

About the EQUALISE Study

The EQUALISE study is a Phase 1b open-label proof-of-concept multiple ascending-dose clinical study of itolizumab in patients with systemic lupus erythematosus and lupus nephritis. The study is evaluating the safety and tolerability of subcutaneous delivery of itolizumab in patients with systemic lupus erythematosus and lupus nephritis. The treatment period for patients with systemic lupus erythematosus is two weeks in duration, while treatment for patients with active proliferative lupus nephritis is 24 weeks in duration.

About Itolizumab

Itolizumab is a clinical-stage, first-in-class anti-CD6 monoclonal antibody that selectively targets the CD6-ALCAM signaling pathway to selectively downregulate pathogenic T effector cells while preserving T regulatory cells critical for maintaining a balanced immune response. This pathway plays a central role in modulating the activity and trafficking of T cells that drive a number of immuno-inflammatory diseases. Equillium acquired rights to itolizumab through an exclusive partnership with Biocon Limited.

About Equillium

Equillium is a clinical-stage biotechnology company leveraging deep understanding of immunobiology to develop novel products to treat severe autoimmune and inflammatory disorders with high unmet medical need. Equillium is developing itolizumab for multiple severe immuno-inflammatory diseases, including acute graft-versus-host-disease (aGVHD), lupus/lupus nephritis and uncontrolled asthma.
