BesançonAges 18 years+ - NCT04195633RecruitingPhase 2
Haploidentical donor stem cell transplant to treat blood cancers
This Phase 2 trial tests whether a specific stem cell transplant method (from a related “half-matched” donor) plus conditioning chemo and radiation can improve outcomes for several blood cancers. It may help people whose cancer is in remission but still considered high risk, or those who have had limited response after prior treatment.
Seattle, WashingtonAges 6 months+ - NCT04197596RecruitingPhase 1/Phase 2
BK infection immune-cell treatment after transplant or weak immunity
This Phase 1/2 study tests lab-made immune cells that specifically target BK virus in people whose BK infection keeps coming back or doesn’t improve. It may help by boosting the body’s ability to clear the virus, especially when standard antiviral treatments don’t work or can’t be tolerated.
San Francisco, CaliforniaAges 1 month–79 years - NCT04198740Recruiting
Test tear fluid and eye chemistry patterns in eye surface diseases
This study looks at tiny chemical patterns in tear fluid to better understand different causes of eye surface problems. Your participation may help researchers compare healthy eyes with conditions like dry eye, infections, or allergies.
Montreal, QuebecAges 18 years+ - NCT04203979Recruiting
Sepsis care tailored to patients
This study looks at how to better recognize and manage sepsis (a serious body-wide reaction to infection) and tailor care to the individual. You may be eligible if you are newly admitted to the emergency department and your care is handled by a rapid response team for sepsis.
OsloAges 18 years+ - NCT04218422Recruiting
Battlefield-style ear acupuncture for hidradenitis pain
This trial tests a type of ear acupuncture (“battlefield acupuncture”) to reduce pain from hidradenitis suppurativa, a long-term skin condition. You may be eligible if your hidradenitis pain is frequent and your treatments are stable.
Dearborn, MichiganAges 18 years+ - NCT04226313Recruiting
Home self-swab tests for people not doing cervical screening
This study looks at whether a home self-sampling swab can help people who haven’t joined cervical cancer screening in the past few years. If you qualify, you’ll be asked to collect a swab yourself so it can be tested, aiming to make screening easier to access.
OlomoucAges 30–65 - NCT04230356RecruitingPhase 2
Viral immune T-cells for viral infections after stem cell transplant
This Phase 2 study tests donor-made immune T-cells that specifically target viruses to treat or prevent viral infections after a stem cell transplant. It may help your body control dangerous viruses like adenovirus, CMV, EBV, and BK virus, while checking safety with different timing of the treatment.
Cincinnati, OhioAges Any age - NCT04231565Recruiting
Testing antiviral medicines for hepatitis B with normal liver blood tests
This trial studies how well nucleoside (nucleoside-acid) type antiviral medicines control hepatitis B in people whose liver enzyme test (ALT) is currently normal. It may help those with active hepatitis B but no major liver inflammation on recent bloodwork.
Guangzhou, GuangdongAges 18–65 - NCT04256798RecruitingPhase 3
Respiratory care after high-risk abdominal surgery
This trial looks at a breathing-focused care plan given around the time of major abdominal surgery to improve recovery and outcomes. You may be eligible if you’re having a large midline abdominal incision and can be followed after surgery.
Botucatu, São PauloAges 10–100 - NCT04260477RecruitingPhase 3
Testing a new stronger TB retreatment medicine schedule
This trial tests a new “triple-dose” set of medicines to treat people whose tuberculosis (TB) has come back in the lungs. If you qualify, the goal is to improve cure rates and reduce the chance of TB returning again.
NiameyAges Any age - NCT04260022RecruitingPhase 1
Drug study for hard-to-treat CML or Ph+ ALL
This Phase 1 study tests HQP1351 for people with CML or Ph+ ALL that has not responded well to standard targeted pills (TKIs), or those who could not tolerate them. It’s designed to see whether the treatment can work and how safe it is for this difficult-to-treat group.
Birmingham, AlabamaAges 18 years+ - NCT04263792RecruitingPhase 1
Scan trial to track a new tracer in suspected bacterial infections
This Phase 1 study uses a special scan tracer ([18F]F-TMP) to see how it moves in the body and how fast it changes in people with suspected or known bacterial infections. It’s mainly testing the scan’s behavior and safety, which may help future infection-targeting imaging.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04271397Recruiting
Testing immune blood markers in tuberculosis care
This study looks at immune system blood tests in adults being treated for active tuberculosis and/or latent tuberculosis infection. The goal is to see if these “immune biomarkers” can help guide or improve tuberculosis management.
LyonAges 18 years+ - NCT04280497Recruiting
Testing fast ways to tell steroid-resistant sepsis from sensitive
This trial studies a quick set of tests to figure out whether a person with severe infection (sepsis) will respond to corticosteroids like hydrocortisone. The goal is to guide treatment sooner and avoid ineffective care.
Garches, Hauts-de-SeineAges 18 years+ - NCT04288674Recruiting
Leptospirosis patient registry study in hospitals
This study records information from people who have invasive (spreading) leptospirosis, a bacterial infection. The goal is to better understand how the disease presents and spreads, which can help improve future care.
Cologne, North Rhine-WestphaliaAges Any age - NCT04292054RecruitingPhase 3
Antibiotics to prevent infection during burn skin graft surgery
This Phase 3 study tests whether giving preventive antibiotics lowers infection risk when you need surgery to remove burned skin and place a skin graft. It may help patients heal with fewer serious infections, but it also depends on your antibiotic allergy and current health status.
ParisAges 18–99 - NCT04291768RecruitingPhase 4
Shorter 5-day antibiotics for certain gram-negative bloodstream infections
This trial tests whether people with a specific type of bloodstream infection caused by gram-negative bacteria can safely take antibiotics for only 5 days instead of longer. It may help by reducing antibiotic exposure if your infection source is controlled quickly.
AalborgAges 18 years+ - NCT04294043RecruitingPhase 1
Gallium IV study for adults with cystic fibrosis and NTM lung infection
This Phase 1 study tests whether an IV medicine called gallium can treat hard-to-treat lung infections (NTM) in adults with cystic fibrosis. It is mainly for people who have not been treated yet for NTM or who have NTM that has not cleared despite antibiotics.
Birmingham, AlabamaAges 18 years+ - NCT04305691RecruitingPhase 2
Ixazomib for skin Kaposi sarcoma in people with HIV

San Diego, CaliforniaAges 18 years+ - NCT04303117RecruitingPhase 1/Phase 2
Test drug PDS01ADC alone and with immunotherapy for Kaposi sarcoma
This Phase 1/2 study tests PDS01ADC, a targeted cancer drug, for advanced Kaposi sarcoma (KS). It also studies how well the drug works when added to the immunotherapy M7824, especially if KS has not responded to prior treatments.
Bethesda, MarylandAges 18–99 - NCT04305769RecruitingPhase 2
Alanyl-glutamine to help treat C. difficile diarrhea
This study tests whether the supplement alanyl-glutamine, given along with standard treatment, can improve outcomes for adults being treated for C. difficile infection (a cause of diarrhea). It may help the body recover better after antibiotics that usually treat C. difficile.
Charlottesville, VirginiaAges 18–105 - NCT04305808Recruiting
Study of gut, bladder, and vaginal bacteria in recurrent UTIs
This study looks at the bacteria living in the vagina, urine tract, and stool to learn why some women get repeated urinary tract infections (UTIs). The results may help doctors better prevent or treat UTIs in the future.
