A new treatment paradigm
for Respiratory Long COVID

The current view is that Respiratory Long COVID is caused by lung scarring. Our research suggests it is driven by a novel mechanism, which can be diagnosed using a proprietary biomarker and targeted with repurposed drugs.

The unmet need

Respiratory Long COVID: 4M+ U.S. adults with no approved treatment options.

A different approach

With the field focused on scarring, our data points to a reversible disease mechanism.

The prevailing view

Lung scarring occurs in patients after severe acute COVID-19, and in mouse models of disease. These observations have led the field to anchor on lung scarring as the mechanism to target in drug trials.

Clinical reality

In practice, most patients with Respiratory Long COVID had mild acute COVID-19, and show no evidence of scarring at all.

What we have found

The primary culprit is a neuroimmune mechanism.

This mechanism can be quantitatively measured using standard clinical testing and targeted with existing drugs, opening a new and reversible treatment target that the field has overlooked.

What we have found

The primary culprit is a neuroimmune mechanism.

Research led by our Ivy League academic team has shown that this mechanism can be quantitatively measured using standard clinical testing and targeted with existing drugs. Our findings represent a breakthrough in Long COVID research, which has long been limited to subjective symptom scores and poorly validated disease targets.
