LA JOLLA, Calif., May 13, 2021 (GLOBE NEWSWIRE) -- Equillium, Inc. (Nasdaq: EQ), a clinical-stage biotechnology company developing itolizumab to treat severe autoimmune and inflammatory disorders, today announced that an abstract highlighting positive data from the EQUATE study of itolizumab in acute graft-versus-host disease (aGVHD) has been accepted for oral presentation at EHA2021 Virtual Congress. The annual meeting of the European Hematology Association will be held virtually June 9 – 17, 2021.
The abstract describes results from the ongoing Phase 1b EQUATE study of itolizumab in combination with steroids for the first-line treatment of patients with aGVHD. The primary cohorts enrolled 10 patients with Grade III-IV aGVHD that received itolizumab within 72 hours of first steroid dose, whereas the expansion cohorts also include subjects with Grade II aGVHD and an Ann Arbor Score of 2 or 3 that received itolizumab within 7 days of first steroid dose. The company will present data on all patient cohorts in the EQUATE study. The benefit-risk profile observed support continued evaluation in future randomized controlled trials.
Title: Interim results from the EQUATE Study: Preliminary safety and efficacy of itolizumab, a novel targeted anti-CD6 therapy, newly diagnosed acute graft-versus-host disease
First Author: John Koreth – Dana Farber Cancer Institute, Harvard Medical School
Presentation Session: Stem cell transplantation - GvHD
Date and Time: Friday, June 11, 3:00 am ET
Abstract Code: S238
About Graft-Versus-Host Disease (GVHD)
GVHD is a multisystem disorder that is a common complication of allogeneic hematopoietic stem cell transplants (allo-HSCT) caused by the transplanted immune system recognizing and attacking the recipient’s body. Symptoms of GVHD include rash, itching, skin discoloration, nausea, vomiting, diarrhea, and jaundice, as well as eye dryness and irritation.
GVHD is the leading cause of non-relapse mortality in cancer patients receiving allo-HSCT, and its risk limits the number and type of patients receiving HSCT. GVHD results in high morbidity and mortality, with five-year survival of approximately 53% in patients who respond to steroid treatment and mortality as high as 95% in patients who do not respond to steroids. There are no approved treatments for first-line aGVHD. Published literature (MacMillan et al., 2015) describes background response rates to high-dose steroid administration in severe high-risk patients as 43% overall response rate and 27% complete response.
About the EQUATE Study
The EQUATE study is a Phase 1b/2 trial to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and clinical activity of itolizumab for first-line treatment in patients who present with aGVHD (NCT 03763318). The Phase 1b part of the trial is an open-label dose escalation study in adult patients who present with high-risk aGVHD and typically respond poorly to steroids. The Phase 1b data will inform selection of the dose to be used in the next phase of development for the program.
Itolizumab 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.
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.
