Phase II Study Demonstrates Utility of DxTerity's Modular Immune Profiling Test for Predicting & Monitoring Iberdomide Response in Lupus Patients

 

LOS ANGELES, Nov. 4, 2020 /PRNewswire/ -- DxTerity Diagnostics is excited to share the results of a new study on the treatment of Systemic Lupus Erythematosus (SLE) that was aided by DxTerity's Modular Immune Profile (MIP) test. The results of the clinical trial will be presented at the ACR Convergence 2020, the annual American College of Rheumatology virtual conference on Saturday, November 7th Abstract 0851.  The international team of scientists that led the study used DxTerity's MIP test to measure the expression levels of immune system-related genes over time. Their findings demonstrate MIP's utility in identifying patient sub-groups that are most likely to respond to treatment, as well as longitudinally monitoring therapy response.

 

The BMS Iberdomide study is an excellent example of how DxTerity is changing the future of autoimmune clinical trials.

"The BMS Iberdomide study is an excellent example of how RNA based Precision Medicine is changing the future of autoimmune clinical trials and treatment.  Our MIP test allows for the identification of therapy responders from a fingerstick collector blood sample that a patient can perform in a doctor's office or the comfort of their home."

DxTerity's Modular Immune Profiling Test includes 12 immune system expression modules

The Modular Immune Profiling Test uses Chemical Ligation Dependent Probe Amplification (CLPA) on small volumes of whole blood samples. The MIP test is composed of 12 immune system expression modules, including Type I and Type II Interferon, plasma and plasmablast cells, neutrophils, B cells, T cells, and T cell exhaustion. The test allows researchers to measure changes in the expression of multiple genes; these changes occur in response to drug treatment and provide characterization of therapy response in clinical studies.

Monitoring of Iberdomide response using DxTerity's MIP Assay

The study presented at the ACR Convergence this month demonstrated the utility of the MIP test for monitoring the changes in important inflammatory biomarkers. The randomized, double-blind clinical trial assessed the effects of treatment with Iberdomide on SLE associated genes and showed a decrease in pro-inflammatory signatures over time. The changes in gene expression were measured using whole blood samples collected by DxTerity's DxCollect® micro-collection device. The MIP assay results were compared to the current standard assessment methods and showed a high concordance with flow cytometry assays, while using a significantly smaller amount of blood.

Self-collected samples enable at-home patient monitoring, possibly eliminating the need for blood draws

These results highlight the potential of the MIP assay to replace or supplement current testing methods, simplifying the process of monitoring patients with autoimmune diseases like SLE, Multiple Sclerosis, Inflammatory Bowel Disease, and Rheumatoid Arthritis. The complex nature of autoimmune disease requires continuous assessments of multiple biomarkers to understand how interrelated immune pathways change in response to treatment. Today, this requires frequent lab visits for patients, which can be a burden. DxTerity's at home micro-collection device, however, enables remote monitoring with just a small amount of blood, and the MIP assay provides sensitive detection comparable to flow cytometry, a method requiring a full blood draw. MIP is being further developed to expand its range of applications for the longitudinal monitoring of a patient's immune health during clinical trials and investigational studies.
