Resverlogix Presents New Complement Data and Establishes Renal Clinical Advisory Board at the 53rd Annual European Renal Association - European Dialysis & Transplant Association Congress (ERA-EDTA)
Calgary, Alberta (ots/PRNewswire) - "Apabetalone, a selective bromodomain extra-terminal (BET) protein inhibitor that significantly decreases abundance and activity of complement proteins"
Resverlogix Corp. ("Resverlogix" or the "Company") (TSX:RVX) announces that new data was presented at the ERA-EDTA Congress in Vienna, Austria in a poster titled: "Apabetalone (RVX-208), a Selective Bromodomain and Extra-Terminal (BET) Protein Inhibitor, Decreases Abundance and Activity of Complement Proteins in Vitro, in Mice and in Clinical Studies". The Company is also pleased to announce the formation of an International Renal Clinical Advisory Board (RCAB) for the future development of apabetalone into expanded renal indications.
New Complement Data Announced at ERA-EDTA Congress - Vienna, Austria
The immune system is the body's way of protecting itself from attacking foreign invaders, such as bacteria, viruses, illness, and disease. The complement cascade is part of this protective response, however pathological activation of the cascade underlies multiple human diseases including several inflammatory, autoimmune, neurodegenerative and infectious diseases.
New data demonstrated that when exposed to apabetalone, primary human liver cells significantly downregulate the expression of complement components. This was observed at both the gene expression and protein level, and occurred at steady state (when unstimulated) and when the cells were stimulated with factors known to cause inflammation and immune response activation. This is particularly important in conditions where these factors are overactive or present in excessive quantities. Moreover, in an apabetalone treated mouse model, where mouse liver cells are replaced with human liver cells, reductions in expression of components C4, C9 and MBL2 mRNA of the complement cascade, decreased by 36 percent, 46 percent and 61 percent respectively. To establish if the observed decrease in protein abundance affected activity, hemolytic assays were performed on 11 plasma samples from patients with cardiovascular disease (CVD) at baseline, and after 26 weeks of apabetalone treatment. Results showed a significant decrease in activity of approximately 26 percent (p<0.01) in both assays. No increase in infections was reported in phase 2 trials.
This effect of apabetalone treatment on complement component expression and cascade activity may have an impact on the pathologic activation of this cascade in Chronic Kidney Disease (CKD). The potential of apabetalone for the treatment of high-risk diabetes and CKD patients is currently being explored in the Company's Phase 3 BETonMACE clinical study.
Dr. Kamyar Kalantar-Zadeh, Chairman of the RCAB, stated, "BET inhibition with apabetalone represents a novel and compelling approach for diabetes and CKD treatment. This data in combination with previously published findings on novel biomarkers and pathways affected by select BET inhibition with known roles in CVD and CKD such as, coagulation, vascular calcification and inflammation, provide a potentially unique and multifactorial approach to disease reduction. The RCAB intend to examine expanded opportunities in renal disease where patients have a significant risk for major adverse cardiac events (MACE) such as death, stroke, heart failure and myocardial infarction".
"This new data is an important step for the Company as we continue to develop our proprietary BET data for high risk CVD patients and apply these learnings into additional indications in kidney and renal orphan diseases," said Mr. Donald McCaffrey, President and CEO. "The data showing that select BET inhibition is modulating key pathways and proteins known to play a role in renal disease, is directly responsible for attracting world-class leaders in the field of renal disease research to help expand and direct our efforts."

Resverlogix is developing apabetalone (RVX-208), a first-in-class, small molecule that is a selective BET (bromodomain and extra-terminal) inhibitor. BET bromodomain inhibition is an epigenetic mechanism that can regulate disease-causing genes. Apabetalone is the first and only BET inhibitor selective for the second bromodomain (BD2) within the BET protein called BRD4. This selective inhibition of apabetalone on BD2 produces a specific set of biological effects with potentially important benefits for patients with diseases such as high-risk cardiovascular disease (CVD), diabetes mellitus (DM), chronic kidney disease (CKD), Alzheimer's disease, Orphan diseases, and peripheral artery disease, while maintaining a well described safety profile. Apabetalone is the only selective BET bromodomain inhibitor in human clinical trials, currently in a Phase 3 trial BETonMACE in high-risk CVD patients with type 2 DM and low high-density lipoprotein (HDL).
