Herpesviridae infectious disease

This phase 1 trial tests a higher dose of the experimental HIV vaccine VIR-1388 in about 12 adults aged 18 to 55 who already carry cytomegalovirus (CMV). The vaccine uses a weakened CMV virus to deliver HIV proteins, aiming to trigger a strong immune response. Participants receiv…

This early-stage trial is testing a new mRNA vaccine called VXCO-102 against Epstein-Barr virus (EBV) in 45 healthy adults aged 18 to 25. The main goal is to check if the vaccine is safe and triggers an immune response. EBV is a common virus that can cause mononucleosis and is li…

This study tests a new mRNA vaccine called SYS6017 to prevent shingles, a painful rash caused by the chickenpox virus. About 800 healthy adults aged 40 and older will receive either the new vaccine, a placebo, or an existing shingles vaccine. Researchers will check how well the v…

This phase 2 trial tests a new mRNA vaccine called IN001 for preventing shingles in healthy adults aged 50 to 79. Researchers will compare three dose levels of IN001 against the existing Shingrix vaccine to see how safe and effective they are. The study involves 480 participants …

This trial tests whether adding a clinical pharmacist to dental care can improve how oral mucosal disorders — such as oral lichen planus, recurrent canker sores, burning mouth syndrome, oral thrush, and herpes infections — are managed. Dentists in some clinics will get pharmacist…

This study investigates whether two common vaccines—the shingles vaccine (RZV) and an RSV vaccine (RSVPreF3)—can slow the buildup of fatty plaque in the coronary arteries. The trial enrolls adults aged 50 and older who are at risk for cardiovascular events. Participants receive e…

This study tests a drug called Sintilimab, which is normally used for cancer, to see if it can help people with HIV who have infections that won't go away with standard treatment. The drug works by 'waking up' exhausted immune cells. Fifty adults with HIV and a hard-to-treat infe…

This study tests whether adjusting the dose of anti-rejection drugs can help control CMV infection in organ transplant recipients. About 100 adults who have had a kidney, liver, heart, lung, or pancreas transplant and now have a CMV infection will take part. Researchers will moni…

This study tests whether valganciclovir, a drug that stops CMV from multiplying, can safely lower CMV levels in the blood of people with advanced HIV. About 130 adults and adolescents with very weak immune systems will be randomly assigned to take either valganciclovir or a place…

This phase 2 trial tests a new drug called zuberitamab as a first-line treatment for EBV infection in 20 adults who have had a stem cell transplant. EBV can cause a serious complication after transplant, and current treatments don't work for everyone. Zuberitamab is designed to b…

This study tests two different drug combinations to prevent cytomegalovirus (CMV) infection in kidney transplant patients who are at high risk. Thirty adults who are CMV-positive before transplant will receive either tacrolimus plus mTOR inhibitors with early antiviral treatment,…

This study tests whether the antiviral drug aciclovir (or its pill form valacyclovir) works better than a placebo for treating meningitis caused by the herpes simplex virus type 2 (HSV-2). About 150 adults with confirmed HSV-2 meningitis will receive either the drug or a placebo,…

This study will test a new blood test that looks for tiny molecules called miRNAs to detect HCMV infection earlier in people who have received a stem cell transplant. The standard DNA test can miss early signs, so researchers hope this new method will give doctors a head start. A…

This study tests whether the drug rituximab can safely clear Epstein-Barr virus (EBV) from the blood of people who have received a solid organ transplant. High levels of EBV can lead to a serious cancer called post-transplant lymphoproliferative disorder (PTLD). The trial will en…

People with multiple sclerosis or neuromyelitis optica spectrum disorder who take anti-CD20 drugs have a higher risk of shingles. The shingles vaccine is recommended for them, but the drug may weaken its effect. This trial compares two dosing schedules: one gives the second shot …

This study investigates whether the drug letermovir can prevent cytomegalovirus (CMV) infection in adults who have received a kidney or liver transplant and have been previously exposed to CMV. Participants take one letermovir tablet daily for 84 days after transplant. The goal i…

This trial tests whether a single dose of a live-attenuated shingles vaccine can effectively boost immunity in adults aged 50 and older who have already received the recombinant shingles vaccine. The study measures antibody and cellular immune responses after the booster. If it w…

This study tests an investigational vaccine that combines protection against measles, mumps, rubella, and chickenpox (varicella) in a single shot. It will be given as a second dose to healthy children aged 4 to 6 years who have already received a first dose of a similar vaccine. …

This study tests if letermovir works as well as valganciclovir in preventing CMV infection in 300 kidney transplant patients who are CMV-positive. Both drugs are given for 90 days after transplant. Researchers will also check if letermovir is easier to tolerate and how long it ta…

This study tests whether a short course of the steroid prednisolone can prevent paradoxical immune reconstitution inflammatory syndrome (IRIS) in people with AIDS who have low CD4 counts and are starting HIV treatment. About 131 participants will receive either prednisolone or no…

This study tests a new shingles vaccine in 135 healthy adults aged 50 and older. Researchers will compare the immune response and safety of the new vaccine against an existing one to find the best dose. The goal is to prevent shingles, a painful rash caused by the chickenpox viru…

This early-stage study tests whether specially prepared immune cells from a donor can prevent Epstein-Barr virus (EBV) infection in people who have received a stem cell transplant. About 9 to 18 participants will receive the cells and be monitored for side effects and infection. …

This study tests whether an extra dose of the shingles vaccine (Shingrix) can boost immunity in people who have had a solid-organ transplant, like a kidney or liver. About 30% of transplant patients still get shingles after the standard two-dose vaccine, likely due to immune-supp…

This study looks at whether the shingles vaccine can prevent shingles and improve survival in 500 lung cancer patients. Participants will either receive the vaccine or not, and researchers will track shingles cases and survival rates over time. The goal is to see if the vaccine o…

This study tests whether dexamethasone palmitate, a steroid, can better relieve shingles pain and prevent long-term nerve pain compared to standard care. About 954 adults with shingles rash and severe pain will receive the drug by injection or infusion. Researchers will track pai…

This study tests a special gel applied to the skin to see if it can quickly reduce pain from shingles. Thirty adults with shingles-related pain will receive a single application of the gel. Researchers will measure pain levels before and after application, focusing on relief with…

This study looks back at medical records of 200 adults who received organ transplants in Argentina between 2017 and 2024 to see how often cytomegalovirus (CMV) infections become resistant to standard antiviral drugs. Researchers will identify cases where the virus does not respon…

This study will follow 1000 kidney transplant patients for one year to see if monthly blood tests for certain viruses (CMV, BK, and TTV) can help predict and prevent serious infections and kidney damage. The goal is to learn how the body's immune system and virus levels relate to…

This study looks at whether measuring two new viral markers (CMV-RNA and TTV-DNA) in the blood can give a clearer picture of CMV infection in patients who have had a stem cell transplant and are taking the drug letermovir to prevent CMV. Researchers will track 290 adult transplan…

This study follows 123 stem cell transplant patients to see if measuring their immune response to CMV after stopping a preventive drug (letermovir) can predict late infections. Participants will have regular blood tests up to 200 days after transplant. The goal is to learn whethe…

This study looks at how CMV (a common virus) changes the immune system in people who have had a kidney transplant. Researchers will take blood samples from 60 patients to compare immune responses in those with and without CMV infection. The goal is to understand why CMV may incre…
