What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new treatment called Xiflam to determine its effectiveness for Long COVID, a condition where symptoms from a past COVID-19 infection persist for weeks or months. Participants will take either Xiflam or a placebo (a pill with no active ingredients) once a day for 12 weeks to assess Xiflam's safety and effectiveness. The study seeks individuals who had COVID-19, have recovered, and still experience symptoms like extreme fatigue or new eye problems. As a Phase 2 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.

Is there any evidence suggesting that Xiflam is likely to be safe for humans?

Research has shown that Xiflam, also known as tonabersat, is being tested for safety in people with Long COVID. This trial is in an early stage, indicating that initial tests have demonstrated some safety, but more information is needed.

Although detailed safety data for Xiflam is not yet available, reaching this stage suggests it is likely safe enough for human testing. Researchers will closely monitor participants for any side effects, ensuring that any unwanted effects are quickly identified and managed.

For those considering joining the trial, it is important to know that close monitoring is a key part of the study, which helps protect participants' health. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for Post-COVID Syndrome, which often focus on managing symptoms with pain relievers and steroids, Xiflam introduces a unique approach. Xiflam features Tonabersat, a new active ingredient that targets neuronal gap junctions, potentially addressing the neurological aspects of the syndrome directly. Researchers are excited because this mechanism could offer more targeted relief and improve quality of life for those suffering from lingering post-COVID symptoms.

What evidence suggests that Xiflam might be an effective treatment for Long COVID?

Research has shown that Xiflam, which participants in this trial may receive, might help treat Long COVID symptoms. Early results suggest that people taking Xiflam feel better than those taking a placebo. Xiflam reduces inflammation, which is believed to contribute to Long COVID. Studies on similar treatments have shown they can help with symptoms like tiredness and brain fog. While more research is needed, these early findings offer hope for those dealing with Long COVID. ^{1 2 3 6 7}

Published Research Related to This Trial

A study involving 68 participants (14 healthy donors and 54 with confirmed SARS-CoV-2 infection) found that specific cytokines (IL-1β, MIP-1α, and TNF-α) were significantly elevated in patients who developed post COVID-19 symptoms one month after infection, suggesting a link between persistent inflammation and long COVID.

The research indicates that monitoring these inflammatory markers could help predict which patients are at risk of developing long COVID, highlighting the importance of inflammation in the disease's long-term effects.

Two weeks after recovering from COVID-19, patients showed significantly lower levels of various immune cells, including total lymphocytes and T cell subsets, compared to healthy controls, indicating a compromised immune status post-infection.

Despite the lower immune cell counts, patients exhibited elevated levels of several cytokines, suggesting a prolonged hyperinflammatory response that may require ongoing medical monitoring after hospital discharge.

The oXiris® hemofilter, used in critically ill COVID-19 patients, effectively reduced inflammatory markers such as interleukin-6, ESR, and CRP, indicating a positive impact on the inflammatory response.

In a small study, the oXiris® filter improved clinical outcomes in two out of three patients, suggesting its potential as an effective adjuvant therapy for managing severe COVID-19 complications.

In a study of 169 patients recovering from COVID-19, those with more severe initial infections showed a higher prevalence of abnormal pulmonary function tests (PFTs), indicating lasting lung issues post-infection.

While exhaled nitric oxide (FeNO) levels remained normal across all severity groups, patients with severe COVID-19 had significantly elevated levels of distal lung inflammation (CaNO), suggesting that this inflammation could contribute to long-term lung complications like pulmonary fibrosis.
