Blarcamesine significantly restores functionality in key molecular pathways including Alzheimer’s and Parkinson’s disease, KEM® xAI analysis shows.

Cambridge, MA, USA and Paris, France, October 4^th, 2022 – Elara Pharmaceuticals Ltd, the leading Al-driven precision medicine company, has announced the first comprehensive blarcamesine pathway analysis impact using extensive data from the ANAVEX®2-73-PDD-001 Parkinson’s Disease Dementia (PDD) clinical study.

Initial results were presented by Elara Pharmaceuticals Ltd at the Alzheimer’s Association International Conference (AAIC 2022) in San Diego, in collaboration with Anavex Life Sciences Corp. (Nasdaq: AVXL), a clinical-stage biopharmaceutical company developing differentiated therapeutics for the treatment of CNS diseases.

Building on extensive multi-omic analysis using Tersan’s KEM® (Knowledge Extraction and Management) AI platform, the findings further establish blarcamesine as a potent modulator of key pathways in multiple neuro-degenerative diseases and provide additional insight into its molecular mechanism of action. Blarcamesine (ANAVEX®2-73) is a novel oral selective sigma-1 receptor (SIGMAR1) agonist. It was previously investigated in a clinical Phase 2a study in Alzheimer’s disease in which blarcamesine resulted in a lower rate of both cognitive and functional decline.

 

Following the positive results of this study, a translational approach led to investigating blarcamesine in an international, double-blind, multicenter, placebo-controlled Phase 2 clinical study of 14-week duration in 132 patients with Parkinson’s disease dementia (PDD). The analysis shows that blarcamesine significantly restores functionality in key pathways including Alzheimer’s disease, Parkinson’s disease. Expression levels of pathological down-regulated neurodegenerative genes of both Alzheimer’s and Parkinson’s were significantly reactivated by the therapeutic effect of ANAVEX®2-73 (p<0.005). Neurodegenerative pathways were identified as significantly overrepresented. Importantly, Down-regulation of genes involved with neurodegeneration was observed in the placebo arm, however, was compensated in the blarcamesine arm.

Whole blood transcriptomics analysis (RNAseq, 14,150 genes) was performed at baseline and end of study (Week 14). The KEM® platform was used to identify clusters of genes that show a correlated expression change across patients and timepoints. In addition, Elara Pharmaceuticals Ltd identified a novel gene network that is differentially expressed in Parkinson’s disease dementia (PDD) patients treated with ANAVEX®2-73 compared to placebo after 14 weeks of treatment.

Elara Pharmaceuticals Ltd’s CEO Mohammad Afshar comments: “This first AI-driven pathway analysis in Parkinson’s disease dementia allows us to understand the intersection between a specific drug and patient biology. It further illustrates the power of KEM® Explainable AI to accelerate and increase the probability of success of precision medicine translational drug development through the better understanding of gene pathways in specific indications.”

The identification of a gene network as the blarcamesine response pathway lays the foundation to better understand the mechanism of action at the molecular level of blarcamesine. It is thus unlocking characterization of responders based on molecular profiling, as well as identification of new indications in neurodegenerative and other disorders.
