This study compares outcomes for people with chronic hepatitis B who have long-term, stable viral suppression: stopping their antiviral medicine versus continuing it. It may help answer whether it’s safe to stop treatment in the right patients.
Hong Kong, Hong Kong SARAges Any age - NCT03795662Recruiting
Surviving Pneumonia
This trial studies treatment for pneumonia by enrolling people who have pneumonia signs on a chest X-ray plus typical symptoms like fever, cough, trouble breathing, or chest pain. It may help doctors test approaches for better outcomes after pneumonia.
HillerødAges 18 years+ - NCT03808922RecruitingPhase 3
DAS181 treatment for COVID-19 lung infection in immune-compromised adults
This Phase 3 trial tests DAS181 to treat lower lung (chest) viral infections in people with weakened immune systems, including a COVID-19 subgroup. It may help by targeting certain viruses in the lungs, but joining depends on your oxygen needs, recent diagnosis, and other safety factors.
Duarte, CaliforniaAges Any age - NCT03813862Recruiting
Study tracking medicines from clinic records
This is an observational study that collects information about what medicines patients receive. It uses data already recorded in participating clinics’ computer health records to better understand medication use over time.
Durham, North CarolinaAges birth+ - NCT03818334RecruitingPhase 2/Phase 3
Cyclophosphamide after transplant for blood cancer without sibling donor
This trial studies giving cyclophosphamide after a stem cell transplant when there is no matched sibling donor, but a well-matched unrelated donor is available. It aims to improve outcomes for people with blood cancers undergoing this transplant.
São Paulo, São PauloAges 1–75 - NCT03825458Recruiting
Study tracking hepatitis B viral RNA in blood
This study builds a group of people to measure small hepatitis B “viral RNA” signals in the blood. The goal is to see if these measurements could help researchers find a functional cure and better understand who may respond over time.
LyonAges 18 years+ - NCT03825874Recruiting
Study digestive side effects after antibiotics for UTIs in kids
This study looks at possible effects on a child’s digestive system after standard antibiotics are used to treat a fever-related urinary tract infection (UTI). It may help doctors better understand what side effects to expect and how to manage them.
Charenton-le-PontAges 3 months–3 years - NCT03826433RecruitingPhase 1
Study stem cell treatment for worsening hepatitis B cirrhosis
This Phase 1 study tests a stem cell product to see if it is safe and how it affects people with worsening hepatitis B-related cirrhosis. It may help researchers understand whether the treatment could improve liver function in this stage of illness.
Changsha, HunanAges 18–60 - NCT03827694Recruiting
Testing a noninvasive scan for serious lung mold infections in kids
This study uses noninvasive breathing/relates imaging (MRI or CT) to help diagnose mold infections in the lungs in children and young adults. It may help doctors find these infections sooner, especially in people with weakened immune systems.
Little Rock, ArkansasAges 4 months–21 years - NCT03830320RecruitingPhase 1
PET scan to look for blood clots in the heart or lungs
This Phase 1 study uses a PET scan to detect blood clots (thrombosis) in specific groups of people. It’s testing how well the scan can find clots and how it should be timed with other heart or illness tests.
Boston, MassachusettsAges 18–85 - NCT03828773Recruiting
Azole antifungal prevention for leukemia during low white blood counts
This trial tests whether using a targeted antifungal medicine (aimed at PTX3) can better prevent serious fungal infections in adults with AML or a related bone marrow disease who will have very low neutrophils. It may help lower the risk of dangerous infections during intensive chemotherapy hospital stays.
Ghent, BelgiumAges 18 years+ - NCT03848962Recruiting
Share leftover or collected samples for research
This study helps collect and share human samples (like blood or other specimens) so researchers can do new studies. It’s mainly about providing samples for research use, not testing a treatment on you.
Huntsville, AlabamaAges 1 month–89 years - NCT03869619Recruiting
Real-life data study for adults with recent lymphoma
This study collects “real-world” health information about adults whose lymphoma was diagnosed within the last 6 months. It aims to better understand lymphoma types and how patients do over time, using data from everyday care rather than testing a new drug.
ArrasAges 18 years+ - NCT03878121RecruitingPhase 1
Ad4-HIV vaccine study for healthy adults and partners
This Phase 1 study tests whether an experimental HIV vaccine (made from a harmless viral vector) is safe and helps the body build immune defenses. It includes healthy volunteers and, in some groups, their close partners, with careful screening and follow-up visits.
Bethesda, MarylandAges 18–65 - NCT03884673Recruiting
Simpler two-drug HIV treatment with dolutegravir and lamivudine
This trial studies whether taking dolutegravir plus lamivudine (a simpler two-drug regimen) can work as well as a standard three-drug HIV regimen for people who have reasons they can’t stay on the usual medicines. You may be offered free treatment if you meet the safety checks and can attend follow-up visits.
Guangzhou, GuangdongAges 18 years+ - NCT03889899Recruiting
Device treatment for certain skin, mouth, or surface soft tissue cancers
This trial studies a radiation-emitting device (DaRT) to treat certain cancers on the skin, in the mouth, or in superficial soft tissues. You may qualify if you have a confirmed malignant tumor, enough body strength for treatment, and blood tests and pregnancy status that meet safety limits.
HaifaAges 18 years+ - NCT03892174Recruiting
Removing inflammatory signals during heart surgery for endocarditis
This study tests whether removing certain inflammation signals (cytokines) can help people with severe heart infection (infective endocarditis) who are having heart surgery soon. It may help reduce harmful inflammation around the time of surgery, but it also has several medication and health-condition requirements.
BernAges 18 years+ - NCT03895593Recruiting
Fecal transplant for stubborn intestinal infections
This study looks at “rescue” fecal microbiota transplantation (FMT), which replaces gut microbes using stool from a screened donor, for intestinal infections that have not improved with standard care. It may help patients whose infection keeps coming back or doesn’t respond to treatment.
Nanjing, JiangsuAges Any age - NCT03920618Recruiting
Testing three HBV medicines for severe liver flare (ACLF)
This study compares three hepatitis B (HBV) medicines to see which treatment helps people with a severe liver flare. You may be eligible if you have confirmed HBV and lab results showing significant liver stress.
Guangzhou, GuangdongAges 12–65 - NCT03932461Recruiting
Wound suction vs immediate re-operation for severe bowel infection
This trial compares two ways of treating the abdomen after emergency surgery when there is severe contamination from a bowel perforation causing widespread peritonitis. It may help find the safest approach to control infection and promote healing.
