Anti-inflammatory Compound can Treat Severe COVID-19 Patients

COVID-19 pandemic has infected more than 300 million people with more than 5 million deaths worldwide.

An anti-inflammatory compound can treat systemic inflammation and brain injury in patients with severe COVID-19, reveals a new study.

Also, the compound significantly reduces their chances of death, according to a new study from UTHealth Houston and other institutions.

Two COVID-19 Mysteries Unraveled
Researchers unravel two important mysteries related to COVID-19. They found six biomarkers that are responsible for severe COVID-19 and also discovered the mechanism of blood clotting in COVID-19.

‘COVID-19 pandemic has infected more than 300 million people with more than 5 million deaths worldwide.’

A team of researchers including UTHealth Houston faculty members Aaron M. Gusdon, MD, assistant professor in the Vivian L. Smith Department of Neurosurgery with McGovern Medical School at UTHealth Houston; H. Alex Choi, MD, associate professor in the department as well as the Department of Neurology; and Louise D. McCullough, MD, Ph.D., professor, and Roy M. and Phyllis Gough Huffington Distinguished Chair in the Department of Neurology, conducted a multi-site, randomized, double-blind, placebo-controlled, adaptive Phase 2 trial evaluating the safety and efficacy of an anti-inflammatory compound, called OP-101, in patients with severe COVID-19.

The results of the trial were published today in Science Translational Medicine.

OP-101 for Severe COVID-19 Patients

In the trial, 24 patients classified as having severe COVID-19 across five clinical sites in the U.S. were randomized to receive a single intravenous dose of placebo or OP-101 at 2, 4, or 8 mg/kg. All patients received standard of care, including corticosteroids.

New Clue to Why Men are More Vulnerable to Severe COVID-19
A study shows that Pregnant women pass fewer coronavirus antibodies to unborn boys than girls, which hints men are more vulnerable to severe COVID-19.

“OP-101 is a novel nanotherapeutic compound that specifically targets activated macrophages and microglia, the primary immune cell in the brain,” said Gusdon, who was the first author of the study. “Due to its excellent safety profile, we were excited to offer this therapy to these critically ill patients at Memorial Hermann Hospital.”

Hyperinflammation triggered by SARS-CoV-2 is a major cause of disease severity in COVID-19. OP-101 was found to be better than a placebo at decreasing inflammatory markers, as well as better at reducing markers of neurological injury, including neurofilament light chain and glial fibrillary acidic protein.

Severe COVID-19 Infection Could be Rare in Babies
Severe COVID-19 infection appears rare in newborn babies, suggests the UK-wide analysis, led by researchers from Imperial College London and the Nuffield Department of Population Health at the University of Oxford.

Additionally, the risk for the composite outcome of mechanical ventilation or death at 30 or 60 days after treatment was 71% for patients receiving the placebo, but just 18% for patients in the pooled OP-101 treatment arms. At 60 days after treatment, 3 of 7 patients given placebo and 14 of 17 patients treated with OP-101 survived.

The data shows that OP-101 was well tolerated in the critically ill patient population and could serve as an effective treatment for patients hospitalized with COVID-19.

Around 1 in 3 Young Adults may Face Severe COVID-19: Study
As the number of young adults infected with the COVID-19 surges throughout the nation, a new study indicates that youth may not shield people from serious disease.

“Although this was a small-dose escalation trial, there was a strong signal toward benefit at both acute and chronic time point,” Gusdon said. “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.”

What is OP-101?

OP-101 is a nanotherapeutic compound that has previously been evaluated in several animal models of inflammatory disease and has shown superior anti-inflammatory and anti-oxidant effects.

The COVID-19 pandemic has resulted in more than 300 million people infected globally, with more than 5 million deaths.
