- NCT03561376RecruitingEarly Phase 1
Zinc ointment versus petroleum jelly after skin surgery
This early-phase trial compares zinc oxide ointment versus petroleum jelly to help healing and scar appearance after certain skin surgeries. You might be able to join if you are having a suitable, uninfected, non-scalp skin incision and can use the study ointment.

Tracking outcomes of fecal transplant for repeated C. difficile
This study looks at how fecal microbiota transplantation (a transplant of healthy gut bacteria) works for people who get C. difficile infection repeatedly. It also focuses on collecting follow-up information to better understand which patients benefit and how.
Worcester, MassachusettsAges 16 years+ - NCT03524222Recruiting
Home hospital care for adults after sudden illness
This trial tests whether certain adults can safely receive hospital-level care at home instead of staying in the hospital, using a home care team. It may help you recover in your own home if your condition fits their plan and you have support at home.
Boston, MassachusettsAges 18 years+ - NCT03474029RecruitingPhase 2/Phase 3
Daily rifapentine treatment test for latent tuberculosis infection
This trial studies whether taking rifapentine every day is safe and helps prevent active tuberculosis (TB) in people who have latent TB infection. It aims to find the best way to stop TB from becoming a serious illness later.
Denver, ColoradoAges Any age - NCT03300830Recruiting
Testing tumors linked to viruses, HIV, and immune disorders
This study collects and analyzes tumor tissue to learn what drives certain cancers and growths linked to viruses, HIV, and immune system problems. Results may help researchers understand disease causes and point to better future treatments.
Bethesda, MarylandAges 18 years+ - NCT03482245Recruiting
Study how body clock proteins affect immune responses in infections
This study looks at how your body’s daily “clock” proteins may influence your immune response during certain serious infections requiring hospital care. If you qualify, researchers will compare immune signals during treatment to better understand what could improve care.
St Louis, MissouriAges 18–65 - NCT03334006RecruitingPhase 2
Tested special immune-targeting treatment after abdominal infection surgery
This Phase 2 study tests whether Pentaglobin®, a blood-product made from immune proteins, helps critically ill people with severe abdominal infection (peritonitis) after the infection source is surgically cleaned up. It targets patients with signs of strong inflammation and severe illness.
ViennaAges 18 years+ - NCT03337932Recruiting
Shorter doxycycline course for multiple early Lyme skin rashes
This study looks at how long to take doxycycline for people who have multiple early Lyme disease skin rashes. It may help find the shortest effective treatment duration while keeping side effects low.
LjubljanaAges 18 years+ - NCT03314974RecruitingPhase 2
Stem cell transplant study for blood cancers
This Phase 2 study tests a strong (myeloablative) stem cell transplant using donor stem cells (allogeneic transplant) for certain blood and bone marrow cancers. The goal is to see how well this approach works and whether it can improve outcomes for people who need transplant-level treatment.
Minneapolis, MinnesotaAges Up to 60 years - NCT03465683Recruiting
Study of germ carriage that produces ESBL enzymes
This study looks at whether certain bacteria that carry ESBL enzymes are spreading between people. To join, you would need lab-confirmed evidence that you carry these bacteria based on routine samples taken during usual care.
BaselAges 1 year+ - NCT03492762RecruitingEarly Phase 1
PET scan study of lung inflammation in never or current smokers
This early research study uses special PET scans to look at lung inflammation linked to a target called CCR2. It may help researchers understand inflammation biology and future treatments, using scan results instead of an investigational drug.
St Louis, MissouriAges 21 years+ - NCT03449706Recruiting
Tracking immune changes in early HIV
This study looks closely at how your immune system and HIV infection markers change right after a new HIV diagnosis. It may help doctors understand the earliest stages of HIV and improve how infections are measured and followed over time.
Ghent, Oost-VlaanderenAges 18–65 - NCT03378102RecruitingEarly Phase 1
AdV-targeted T cells for adenovirus after bone marrow transplant
This trial tests a custom immune cell treatment (T cells made to recognize adenovirus) for people whose adenovirus infection is not improving or who cannot tolerate standard antiviral medicines after a bone marrow transplant. It aims to help your body control the virus and prevent organ complications.
Cleveland, OhioAges 3 months+ - NCT03258567RecruitingPhase 2
Nivolumab for EBV-related lymphomas and abnormal immune illnesses
This trial tests nivolumab (an immune therapy) for people with EBV-positive lymphoma or EBV-driven immune/lymph conditions. It may help shrink tumors or control the disease when standard treatments have not worked or are not suitable.
Bethesda, MarylandAges 12 years+ - NCT03223610RecruitingPhase 1/Phase 2
ViPOR treatment for relapsed or hard-to-treat lymphoma
This Phase 1/2 trial tests a combination of several medicines (venetoclax, ibrutinib, prednisone, obinutuzumab, and Revlimid) for lymphoma that has come back or did not respond. It aims to shrink tumors safely and improve responses in people with specific types of B-cell lymphoma.
Bethesda, MarylandAges 18–120 - NCT03234296Enrolling by invitation
Antibiotics versus placebo for uncomplicated appendicitis
This trial tests whether taking antibiotics alone can treat acute uncomplicated appendicitis, compared with a placebo. If antibiotics work, it may help some people avoid surgery or reduce treatment intensity.
TurkuAges 18–60 - NCT03136146RecruitingPhase 2
Chemo for return or non-responsive blood cancers
This Phase 2 study tests a combination chemotherapy plan for certain leukemia and lymphoma types that have come back or did not respond. It may help shrink or control disease when standard treatment is no longer working.
Houston, TexasAges 15 years+ - NCT03059420Recruiting
Genetic study of strabismus and certain birth eye-movement disorders
This study looks for genetic (inherited DNA) causes of strabismus (eyes that don’t line up) and certain birth conditions that affect eye movement and brainstem/cranial nerves. Your participation may help researchers better understand these conditions and guide future testing and care.
Boston, MassachusettsAges 1 day+ - NCT03135886Recruiting
Testing for HIV in opioid treatment programs
This project studies how to improve offering and completing HIV (and hepatitis C) tests in opioid treatment programs. It may help increase timely follow-up and linkage to care when results are positive.
New York, New YorkAges 18 years+ - NCT03025074Recruiting
Blood sample bank for liver disease research
This study collects blood samples to build a “biobank” (a stored library of samples) for researchers studying liver diseases like hepatitis, fatty liver disease, and liver cancer. It may help future testing and treatments by allowing scientists to study patterns in people with and without liver conditions.
Buffalo, New YorkAges 7 years+ - NCT03146546Enrolling by invitation
Study of sepsis groups to guide future care
This study looks at different types (“endotypes”) of sepsis in adults to better understand what’s happening in the body and how patients may respond. You might be asked to provide information and samples as the study tries to sort sepsis into meaningful subgroups.
Hershey, PennsylvaniaAges 18 years+ - NCT03210935Recruiting
