S-Nitrosylation Therapy for COVID-19
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores a new treatment for severe COVID-19 using S-nitrosylation therapy (SNO Therapy). Researchers aim to determine if this treatment can aid patients with serious breathing issues caused by the virus. Participants will be divided into two groups: one receiving the experimental therapy and the other a placebo (an inactive treatment). Ideal candidates are those currently hospitalized with confirmed COVID-19, experiencing serious respiratory distress, and requiring more than 4 liters of oxygen per minute. As an Early Phase 1 trial, this research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this innovative therapy.
Will I have to stop taking my current medications?
Yes, you will need to stop taking certain medications. The trial excludes individuals taking nitrates, PDE-5 inhibitors, nitric oxide donors, drugs that increase methemoglobin, drugs that interfere with nitrite metabolism, and drugs that may cause low blood pressure.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that S-nitrosylation therapy, which uses nitric oxide, is under investigation as a treatment for severe COVID-19. Past studies on inhaled nitric oxide suggest it might improve breathing and oxygen levels in patients. However, results have been mixed, and further research is necessary to confirm these benefits.
In terms of safety, this treatment remains in the early testing stages, so limited information exists about its effects on people. Early trials focus on assessing safety and determining the appropriate dose. So far, no clear evidence of serious side effects has emerged, but additional studies are required to ensure safety. Prospective trial participants should consider this information.12345Why do researchers think this study treatment might be promising?
Researchers are excited about S-nitrosylation therapy for COVID-19 because it introduces a novel mechanism of action that differentiates it from current treatments, like antivirals and monoclonal antibodies. While standard treatments target the virus directly or modulate the immune response, S-nitrosylation involves delivering SNO, a compound that can release nitric oxide to help regulate inflammation and improve blood flow. This could lead to more effective management of COVID-19 symptoms, potentially offering quicker relief and improved outcomes for patients.
What evidence suggests that S-nitrosylation therapy might be an effective treatment for COVID-19?
This trial will compare S-nitrosylation therapy with a placebo to evaluate its potential in treating COVID-19. Research suggests that S-nitrosylation therapy might help by affecting how the virus enters cells. One study found that S-nitrosylation targets the ACE2 receptor, which the virus uses to infect cells. This targeting could potentially stop the virus from spreading in the body. While the exact benefits are still under investigation, early results indicate this method might slow the virus. However, further research is needed to confirm these possible effects.13678

Are You a Good Fit for This Trial?
This trial is for adults aged 18-89 with confirmed COVID-19, experiencing mild respiratory distress and needing more than 4 liters/min of oxygen but not on active ventilatory support. They must be able to consent or have a representative who can. Excluded are pregnant/breastfeeding individuals, those with certain heart/lung/kidney diseases, anemia, taking specific medications that could interact negatively, or at high risk of methemoglobin formation.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Nitrogen gas
- SNO
Trial Overview
The study tests S-nitrosylation therapy using SNO and nitrogen gas in treating severe acute respiratory syndrome coronavirus (SARS-CoV2) infection. It aims to see if this treatment can help patients breathe better without the need for more intensive breathing support like ventilators.
How Is the Trial Designed?
