An anti-inflammatory compound might have the potential to deal with systemic irritation and mind harm in sufferers with extreme COVID-19 and considerably cut back their probabilities of dying, in response to a brand new examine from UTHealth Houston and different establishments.
A workforce of researchers together with UTHealth Houston college members Aaron M. Gusdon, MD, assistant professor within the Vivian L. Smith Department of Neurosurgery with McGovern Medical School at UTHealth Houston; H. Alex Choi, MD, affiliate professor within the division in addition to the Department of Neurology; and Louise D. McCullough, MD, PhD, professor and Roy M. and Phyllis Gough Huffington Distinguished Chair within the Department of Neurology, carried out a multi-site, randomized, double-blind, placebo-controlled, adaptive Phase 2 trial evaluating the security and efficacy of an anti-inflammatory compound, known as OP-101, in sufferers with extreme COVID-19. The outcomes of the trial have been revealed in the present day in Science Translational Medicine.
In the trial, 24 sufferers categorised as having extreme COVID-19 throughout 5 scientific websites within the U.S. have been randomized to obtain a single intravenous dose of placebo or OP-101 at 2, 4, or 8 mg/kg. All sufferers acquired customary of care, together with corticosteroids.
OP-101 is a novel nanotherapeutic compound that particularly targets activated macrophages and microglia, the first immune cell within the mind. Due to its glorious security profile, we have been excited to supply this remedy to those critically unwell sufferers at Memorial Hermann Hospital.”

Hyperinflammation triggered by SARS-CoV-2 is a serious reason behind illness severity in COVID-19. OP-101 was discovered to be higher than a placebo at reducing inflammatory markers, in addition to higher at decreasing markers of neurological harm, together with neurofilament mild chain and glial fibrillary acidic protein.
Additionally, danger for the composite consequence of mechanical air flow or dying at 30 or 60 days after therapy was 71% for sufferers receiving the placebo, however simply 18% for sufferers within the pooled OP-101 therapy arms. At 60 days after therapy, 3 of seven sufferers given placebo and 14 of 17 sufferers handled with OP-101 survived.
The information reveals that OP-101 was properly tolerated within the critically unwell affected person inhabitants and will function an efficient therapy for sufferers hospitalized with COVID-19.
“Although this was a small-dose escalation trial, there was clearly a strong signal toward benefit at both acute and chronic timepoint,” Gusdon mentioned. “The possibility that this therapy could also benefit patients with other diseases that lead to systemic inflammatory responses, including various forms of brain injury, is extremely exciting.”
OP-101 is a nanotherapeutic compound that has beforehand been evaluated in a number of animal fashions of inflammatory illness and has proven superior anti-inflammatory and anti-oxidant results.
The COVID-19 pandemic has resulted in additional than 300 million individuals contaminated globally, with greater than 5 million deaths.
