COVID-19 Booster Vaccine for Immunocompromised Individuals
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new COVID-19 booster shot (NVX-CoV2372) to determine its effectiveness in boosting the immune response in individuals with weakened immune systems. It targets those with inflammatory bowel disease, such as Crohn's or ulcerative colitis, or those who have undergone a solid organ transplant, like a kidney or liver. Participants should have received at least three doses of a COVID-19 vaccine. Individuals with these conditions who are on specific treatments may be suitable candidates. As a Phase 2 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.
Do I have to stop taking my current medications for the trial?
The trial does not require you to stop your current medications. In fact, it specifies that participants should be on certain medications for IBD or as solid organ transplant recipients.
Is there any evidence suggesting that NVX-CoV2372 is likely to be safe for humans?
Research has shown that the NVX-CoV2372 vaccine, also known as the Novavax COVID-19 vaccine, is generally safe. Most recipients did not experience serious side effects. In studies, various groups tolerated the vaccine well. Some individuals reported mild to moderate side effects, such as pain at the injection site, tiredness, and headache, which typically resolved quickly.
For individuals with inflammatory bowel disease (IBD) or those who have undergone organ transplants, specific safety data on NVX-CoV2372 remains limited. However, the vaccine has demonstrated good safety results in other groups. Additionally, its approval for use in other conditions suggests general safety.
Overall, while specific data for people with weakened immune systems is limited, existing research provides some confidence in its safety.12345Why do researchers think this study treatment might be promising?
Researchers are excited about NVX-CoV2372 because it offers a promising new approach for boosting immunity in immunocompromised individuals. Unlike traditional mRNA or viral vector vaccines, NVX-CoV2372 is a protein-based vaccine, which can provide a robust immune response with potentially fewer side effects. This vaccine uses recombinant nanoparticle technology to introduce a stabilized form of the SARS-CoV-2 spike protein, aiming to enhance the immune response specifically in individuals with conditions like solid organ transplants or inflammatory bowel disease (IBD). This unique method could lead to better protection for those who are typically less responsive to standard vaccines.
What evidence suggests that this treatment might be an effective treatment for COVID-19 in immunocompromised individuals?
Research has shown that the NVX-CoV2372 vaccine is safe and generates a strong immune response across various groups. This trial will assess its effectiveness in immunocompromised individuals, specifically those who have undergone solid organ transplants and those with inflammatory bowel disease (IBD). For participants with IBD, evidence indicates that COVID-19 vaccines are generally safe and effective, though specific data for this group remains limited. In contrast, individuals who have had organ transplants may exhibit weaker immune responses, but studies suggest that vaccines like NVX-CoV2372 can bolster their immunity. Overall, current evidence supports the potential of NVX-CoV2372 to enhance immunity in these vulnerable groups.25678

Are You a Good Fit for This Trial?
This trial is for people with Inflammatory Bowel Disease or those who've had an organ transplant and have already received a COVID-19 vaccine. They should be on specific treatments for their condition but can't join if they've had recent organ rejection, allergies to the vaccine, are pregnant/breastfeeding, recently used steroids for IBD flare-ups, or currently have COVID-19.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Baseline
Baseline visit where blood samples are collected before the booster dose

What Are the Treatments Tested in This Trial?
Interventions
- NVX-CoV2372
Trial Overview
The study tests if a recombinant booster shot (NVX-CoV2372) enhances immune response against COVID-19 in immunosuppressed patients over six months. It involves 120 participants with either IBD or solid organ transplants to see how well their bodies can fight off the virus after getting this extra dose.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Male and females aged 18 to 85 who have IBD and receive the study intervention.
Male and females aged 18 to 85 who are solid organ transplant recipients and receive the study intervention.
