\nEquillium, Inc. (Nasdaq: EQ), a clinical-stage biotechnology company focused on developing novel therapeutics to treat severe autoimmune and inflammatory disorders with high unmet medical need, today announced interim results from the Type B portion of the EQUALISE study evaluating itolizumab, a first-in-class anti-CD6 monoclonal antibody selectively targeting the CD6-ALCAM pathway, in patients with lupus nephritis (LN).\n<\/p>\n
\n\u201cDespite recently approved therapies, 60% of lupus nephritis patients are failing to achieve a complete response at 12 months, highlighting the need for new medicines with differentiated mechanisms,\u201d said Bruce Steel, chief executive officer at Equillium. \u201cWe are very encouraged by the interim data from the LN portion of the EQUALISE study as we observed compelling responses in a patient population with significantly greater baseline proteinuria than recent studies, with a mean baseline UPCR of 5.8 grams. At end of study, 83% of patients achieved a complete or partial clinical response, with 67% reaching a greater than 80% reduction in UPCR. The interim data adds to our conviction in the clinical activity of itolizumab and the potential to be an impactful therapy for patients with lupus nephritis. We look forward to continuing to enroll patients in the Type B portion of the EQUALISE study and anticipate sharing topline data in mid-2023. In parallel, we are engaged with key opinion leaders to prepare for later stage development that we expect can support potential product registration.\u201d\n<\/p>\n
\n\u201cI\u2019m impressed with these promising early and deep reductions in proteinuria, especially given the high nephrotic baseline levels,\u201d said Dr. Kenneth Kalunian, professor of clinical medicine at the University of California San Diego School of Medicine and the lead principal investigator on the EQUALISE trial. \u201cWhat is particularly striking are the higher overall response rates observed early in the treatment course that are not typically achieved with standard of care alone and that look competitive with data emerging from the recently approved drugs. As a clinician, an ideal therapy would safely and rapidly reduce the levels of proteinuria in a greater number of patients as this has been shown to be associated with improved long-term outcomes. These interim results from the EQUALISE study are encouraging and provide the type of signal we\u2019re looking for to advance a drug to larger controlled trials.\u201d\n<\/p>\n
\nThe Type B portion of the EQUALISE study in patients with active proliferative LN is evaluating the safety, tolerability and clinical activity of subcutaneous delivery of itolizumab. Patients must present with greater than 1 gram of proteinuria and positive biopsy to be eligible for the study. During the 24-week treatment period, patients receive a subcutaneous dose of 1.6 mg\/kg every two weeks, with follow up out to 36 weeks. Consistent with standard of care, patients on study also receive 2-3 g\/day of mycophenolate mofetil\/mycophenolic acid (MMF\/MPA), and patients may receive pulse systemic corticosteroids that are rapidly tapered.\n<\/p>\n
\nFor this interim analysis, 13 subjects have been enrolled and dosed, with 11 subjects reaching at least 12 weeks of treatment and 6 subjects reaching 28 weeks or the end of study (EOS). Based on published guidelines for the management of lupus nephritis from the European League Against Rheumatism (EULAR) and European Renal Association-European Dialysis and Transplant Association (ERA-EDTA), clinical activity assessments in this study are focused on the change in UPCR from baseline; proportion of apLN subjects with a complete response (CR), defined as 50% or greater reduction in UPCR and less than 0.5-0.7 g\/g; and proportion of subjects achieving a partial response (PR), defined as 50% or greater reduction in UPCR.\n<\/p>\n
Key findings from the interim analysis of the Type B portion of the EQUALISE study in lupus nephritis:<\/b><\/p>\n \nData reported from the Type B portion of the EQUALISE study are preliminary and subject to change as more patient data become available.\n<\/p>\n \nTop-line data from the Type B portion of the EQUALISE study in patients with lupus nephritis is expected to be announced mid-2023.\n<\/p>\n Webcast and Conference Call<\/b><\/p>\n \nManagement will host a conference call accompanied by a slide presentation to discuss the interim data from the Type B portion of the EQUALISE study in patients with lupus nephritis, for analysts and institutional investors, at 8:00 am ET today, September 27, 2022. To access the call, please dial (888) 350-3846 or (646) 960-0251 and, if needed, provide confirmation number 8770084. A live webcast of the call will also be available on the company\u2019s Investor Relations page at https:\/\/www.equilliumbio.com\/investors\/events-and-presentations\/default.aspx<\/a>. The webcast will be archived for 180 days.\n<\/p>\n About Systemic Lupus Erythematosus (SLE) & Lupus Nephritis (LN)<\/strong><\/p>\n \nSLE 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. LN is a serious complication of SLE, occurring in approximately 30% \u2013 60% of individuals with SLE. LN involves the body\u2019s own immune system attacking the kidneys, causing inflammation and significantly reducing kidney function over time. LN is associated with an increase in mortality compared with the general population and may lead to end-stage renal disease.\n<\/p>\n About the EQUALISE Study<\/b><\/p>\n \nThe EQUALISE study is a two-part Phase 1b open-label proof-of-concept study of itolizumab in patients with SLE and LN. The Type A portion of the study was a multiple ascending-dose clinical study evaluating the safety and tolerability of subcutaneous delivery of itolizumab over a two-week treatment period in 35 patients with SLE. The Type B portion of the study, currently enrolling, is evaluating the safety, tolerability and clinical activity of subcutaneous delivery of itolizumab dosed at 1.6 mg\/kg every two weeks over a 24-week treatment period in up to 20 patients with active proliferative LN.\n<\/p>\n About Itolizumab<\/strong><\/p>\n \nItolizumab is a clinical-stage, first-in-class anti-CD6 monoclonal antibody that selectively targets the CD6-ALCAM pathway. 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.\n<\/p>\n About Equillium<\/b><\/p>\n \nEquillium is a clinical-stage biotechnology company leveraging a deep understanding of immunobiology to develop novel therapeutics to treat severe autoimmune and inflammatory disorders with high unmet medical need. The company\u2019s pipeline consists of the following novel immunomodulatory assets targeting immuno-inflammatory pathways. Itolizumab, a first-in-class monoclonal antibody that targets the CD6-ALCAM signaling pathway which plays a central role in the modulation of effector T cells, is currently in a Phase 3 study for patients with acute graft-versus-host disease (aGVHD) and is in a Phase 1b study for patients with lupus\/lupus nephritis. EQ101, a first-in-class tri-specific cytokine inhibitor that selectively targets IL-2, IL-9, and IL-15, is Phase 2 ready and expected to begin enrolling patients in an alopecia areata study in the fourth quarter of 2022. EQ102, a bi-specific cytokine inhibitor that selectively targets IL-15 and IL-21, is ready for clinical development and expected to begin enrolling patients in a Phase 1 study anticipated to include normal healthy volunteers and celiac disease patients, in the fourth quarter of 2022.\n<\/p>\n \nFor more information, visit www.equilliumbio.com<\/a>.\n<\/p>\n Forward Looking Statements<\/b><\/p>\n Statements contained in this press release regarding matters that are not historical facts are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995.
