Oligomerix's Tau-Targeting Small Molecule Shows Promise in Preclinical Studies

Oligomerix, a New York-based biotech company, has made significant strides in the development of a potential treatment for tau-related neurodegenerative diseases, including Alzheimer's disease (AD). The company's oral small molecule, OLX-07010, has demonstrated promising results in reducing tau protein aggregation and improving motor coordination in preclinical studies.

Preclinical Efficacy in Tau Aggregation Reduction

Researchers at Oligomerix, led by chief scientific officer Eliot Davidowitz, Ph.D., have published their latest findings in the Journal of Neurochemistry on March 12. The study focused on mice with pre-existing tau aggregations in their brains, modeling a rare neurological condition similar to progressive supranuclear palsy.

Treatment with OLX-07010 resulted in a significant reduction of harmful tau bundles compared to untreated mice. This builds upon previous research that showed the molecule's ability to prevent tau from aggregating in genetically predisposed mice.

William Erhardt, M.D., Oligomerix's president and head of development, emphasized the importance of these findings: "This study shows that treatment of mice with pre-existing tau aggregates with OLX-07010 can block the further accumulation of tau aggregates. This is important for Alzheimer's patients because the progression of tau aggregation begins years before clinical symptoms are apparent."

Improved Motor Coordination and Clinical Implications

In addition to reducing tau tangles, the study revealed improvements in motor coordination among treated mice. Using a common test of balance and coordination, mice treated with OLX-07010 were able to maintain their position on a rotating rod for longer periods compared to untreated mice.

These results suggest potential benefits for patients suffering from tauopathies, a class of neurodegenerative diseases characterized by the accumulation of tau protein in the brain. While the current study focused on a model of progressive supranuclear palsy, the researchers note that further work is needed to evaluate the compound's efficacy in Alzheimer's disease models, where tau is not mutated but still forms harmful aggregates.

Dr. Erhardt highlighted the potential for combination therapies in AD treatment: "It is anticipated that drugs targeting amyloid beta aggregates, considered an initiating factor for AD, with drugs targeting tau and inflammation, involved in disease progression, should have a synergistic effect for treating AD."

Advancing to Clinical Trials

Following the success of their preclinical studies, Oligomerix has initiated a phase 1 clinical trial of OLX-07010 in healthy, elderly volunteers. The first doses were administered in February 2023, marking a significant milestone in the compound's development journey.

The ongoing trial aims to assess the safety and tolerability of OLX-07010 in humans, with completion expected later this year. These early-stage clinical studies will provide crucial data to guide the future development of this promising tau-targeting therapy.

As the pharmaceutical industry continues to search for effective treatments for neurodegenerative diseases, Oligomerix's OLX-07010 represents a novel approach that could potentially address the underlying pathology of tauopathies, including Alzheimer's disease. The coming months will be critical as researchers eagerly await the results of the ongoing phase 1 trial, which could pave the way for more advanced clinical studies and bring hope to millions of patients affected by tau-related disorders.
