What is the purpose of this trial?

This trial explores whether two antiviral drugs, typically used for HIV, can reduce symptoms in people with Long Covid. Participants will be randomly assigned to take either Truvada (tenofovir disoproxil/emtricitabine), Selzentry, or a placebo pill daily for 90 days. The goal is to determine if these drugs can lessen the symptom burden, including headaches, memory loss, and fatigue, that many Long Covid sufferers experience. Individuals who have had Long Covid symptoms for at least six months after a confirmed or suspected COVID-19 infection may be eligible to participate. As a Phase 2 trial, the 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 requires that you stop taking any medications that interact with Truvada or Selzentry at least 6 weeks before starting the study. If you are currently using Truvada, Selzentry, or medications affecting EBV replication, you cannot participate.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that both Selzentry and Truvada are generally well-tolerated. Selzentry, or maraviroc, has been studied for conditions like Long COVID. These studies indicate it is usually safe, but monitoring for possible side effects, such as liver problems, is important.

Truvada, which contains tenofovir disoproxil and emtricitabine, also has a good safety record. People using these drugs for conditions like HIV generally tolerate them well. Common side effects include mild nausea or headache, while serious issues are rare.

Both treatments have received FDA approval for other uses, suggesting their safety. However, discussing potential risks with a healthcare provider remains important. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for Long COVID because they introduce antiviral drugs, Tenofovir disoproxil and Emtricitabine, which are typically used for HIV but may help fight lingering viral infections in Long COVID patients. Unlike the standard care options that often focus on symptom management, such as pain relievers or physical therapy, these drugs target the virus directly. Another investigational treatment in the trial, Selzentry, also known as Maraviroc, is being explored for its potential to block specific pathways the virus might use to persist in the body. This approach could offer a new way to tackle the root cause of Long COVID symptoms rather than just alleviating them.

What evidence suggests that this trial's treatments could be effective for Long COVID?

Studies have shown that the drug combination tenofovir disoproxil/emtricitabine may reduce the risk of severe COVID-19. People taking these drugs were less likely to need hospital or ICU care. Research also suggests it could help prevent the virus from spreading in the body. In this trial, some participants will receive tenofovir disoproxil/emtricitabine. Promising results have emerged for Selzentry (also known as maraviroc) in treating Long COVID symptoms. Some patients reported improvement when using maraviroc as part of their treatment. Selzentry is another treatment option under study in this trial. Both treatments are being examined for their potential to ease ongoing Long COVID symptoms. ^{1 3 4 6 7}

Group I: Truvada (Tenofovir Disoproxil Fumarate, TDF/FTC, tenofovir disoproxil/emtricitabine) Experimental Treatment 2 Interventions

Participants will take 300mg tenofovir disoproxil fumarate/200 mg emtricitabine, once per day, and one placebo capsule per day, oral capsule for 90 days.

Group II: Selzentry Experimental Treatment 1 Intervention

Participants will take 300 mg of Selzentry, twice a day, oral capsule for 90 days.

Group III: Placebo Placebo Group 1 Intervention

Participants will take a placebo, twice per day, oral capsule for 90 days.

Published Research Related to This Trial

In a pilot study involving 60 outpatients with recent COVID-19, treatment with tenofovir disoproxil fumarate and emtricitabine showed a significant increase in viral clearance by day 7 compared to standard care, suggesting it may help reduce SARS-CoV-2 viral load.

The treatment was generally well-tolerated, although some patients experienced mild gastrointestinal side effects, indicating that while effective, monitoring for adverse effects is important.

In a study of 50 HIV-infected Koreans receiving Tenofovir disoproxil fumarate (TDF), significant changes in renal function were observed, particularly a decrease in estimated glomerular filtration rate (eGFR) over 144 weeks, indicating potential renal injury from long-term TDF use.

By 144 weeks, 26% of participants experienced a clinically meaningful decline in eGFR, highlighting the importance of monitoring renal function in patients on TDF therapy.

Tenofovir disoproxil fumarate (TDF) is an effective treatment for both HIV and hepatitis B, highlighting its dual role in managing viral infections.

TDF can be combined with other anti-HIV medications to create effective treatment regimens, such as the once-daily pill Truvada, and can also be used prophylactically to prevent HIV transmission, either orally or as a topical gel.

In a study of 59 patients with lamivudine-resistant chronic hepatitis B, switching to tenofovir disoproxil fumarate (TDF) monotherapy significantly improved the rate of complete virological response (CVR) compared to continuing lamivudine plus adefovir, with CVR rates reaching 96.43% at week 48 for the TDF group versus only 29.03% for the LAM plus ADV group.

TDF treatment also led to a higher normalization rate of alanine aminotransferase (75% at week 12) compared to the LAM plus ADV group, indicating better liver function recovery, with no significant adverse effects reported in either treatment group.

In a phase 3 trial with 663 HIV-infected adults, switching from tenofovir disoproxil fumarate (TDF) to tenofovir alafenamide (TAF) showed similar effectiveness in maintaining viral suppression, with 88.6% of TAF users and 89.1% of TDF users achieving HIV-1 RNA levels below 50 copies per milliliter after 96 weeks.

Patients switching to TAF experienced improvements in kidney function and bone mineral density compared to those remaining on TDF, indicating that TAF may offer a safer profile with better long-term health outcomes.

Truvada, a combination of tenofovir disoproxil fumarate and emtricitabine, is effective in treating HIV-1 and HIV-2, allowing for once-daily dosing due to its long half-life and favorable safety profile, including a lower incidence of fat loss compared to other treatments.

The combination has shown superior efficacy in clinical trials compared to other regimens, with a low incidence of resistance mutations, making it a reliable option in highly active antiretroviral therapy (HAART).

Truvada, a once-daily combination pill containing tenofovir disoproxil fumarate and emtricitabine, is expected to be an effective and low-toxicity treatment option for managing HIV, especially in developing countries.

While there is limited clinical efficacy data available, existing studies suggest that emtricitabine is as potent as lamivudine, and trials have shown that tenofovir combined with lamivudine is effective when paired with other antiretroviral medications for up to 96 weeks.

In a study involving 81 HIV-infected adolescents treated with tenofovir disoproxil fumarate (TDF) for a median of 96 weeks, TDF was well tolerated with no deaths or discontinuations due to safety concerns.

At week 144, TDF treatment led to significant improvements in bone mineral density and virologic responses, with only 6% of subjects experiencing notable decreases in bone density, indicating that TDF can be a safe and effective option for treating HIV in adolescents.
