Device removal vs full medical treatment for infected heart devices
This trial compares removing a heart device (like a pacemaker) versus using antibiotics and other medical care to treat an infection. It may help doctors decide the best way to handle infections related to these devices.
CopenhagenAges Any age - NCT06323681Recruiting
Lower-dose interferon for chronic hepatitis B patients who've tried it before
This study tests a lower dose of pegylated interferon for people with chronic hepatitis B whose virus levels dropped significantly during a previous interferon treatment. It aims to see if a second round can further reduce or clear the virus.
Shanghai, Shanghai MunicipalityAges 18–65 - NCT06324552Recruiting
Skin cell function in HS patients
This study looks at how skin cells work in people with hidradenitis suppurativa (HS), a condition that causes painful lumps under the skin. It aims to understand the disease better, which might lead to improved treatments in the future.
InnsbruckAges Any age - NCT06325293Recruiting
Macrolide vs. placebo for mycoplasma pneumonia in children
This trial tests whether azithromycin (a macrolide antibiotic) is better than a placebo for treating mycoplasma pneumonia in children aged 3–17. If your child has pneumonia caused by mycoplasma, this study may help find the best treatment.
Aarau, Canton of AargauAges 3–17 - NCT06326008RecruitingPhase 1
Donor immune cell therapy for leukemia that returned after treatment
This trial tests a two-step approach using donor immune cells to treat children with B-cell acute lymphoblastic leukemia (B-ALL) that has come back or not responded to standard treatments. First, a donor's CD19-targeted cells are given to bridge to a stem cell transplant, followed by CD22-targeted cells to prevent relapse.
Beijing, Beijing MunicipalityAges 1–18 - NCT06578702Recruiting
Intermittent HIV triple therapy study in real life
This study looks at how well intermittent triple therapy works for people with HIV in real-world settings. It may help researchers understand if taking breaks from standard treatment is safe and effective.
StrasbourgAges 18 years+ - NCT07511049RecruitingPhase 2
Brincidofovir for PML brain infection
This pilot study tests an IV medicine called brincidofovir for people with PML, a serious brain infection. The goal is to see if it can stop the virus from causing more damage.
Bethesda, MarylandAges 18–99 - NCT04821154Recruiting
Testing outcomes after revision knee replacement with a Persona system
This study looks at how well a specific revision knee replacement system (the Persona system) works after earlier knee problems or surgeries. You may be eligible if you need a revision knee and can follow follow-up care instructions; the trial also checks for certain infection, bone, and health-safety factors.
Fayetteville, ArkansasAges 18 years+ - NCT05181826Recruiting
Blood collection study for cancer and benign diseases
This study collects blood samples from people with different health conditions (cancer, diabetes, liver disease, etc.) and from healthy volunteers. The goal is to find markers in the blood that could help detect or monitor diseases.
Redondo Beach, CaliforniaAges 18 years+ - NCT07655388Recruiting
Wound healing and dressing changes after hip replacement
This study compares different types of dressings and how often they should be changed after total hip replacement surgery. It aims to find the best way to help the surgical wound heal.
Novi SadAges 65–95 - NCT07599644Recruiting
Sepsis Risk Study in Chinese ICU Patients
This trial studies people with and without sepsis in the ICU to understand why some get very sick from infections. It aims to find better ways to predict who will have complications and guide treatment.
Shaoguan, GuangdongAges 18 years+ - NCT07362862Recruiting
Electrical muscle stimulation to prevent ICU weakness
This trial tests a wearable device that uses mild electrical pulses to stimulate leg muscles, helping prevent muscle weakness in ICU patients with severe infections. It may help you recover strength faster and avoid long-term disability.
Rochester, MinnesotaAges 18–85 - NCT05077527RecruitingPhase 1
CAR-T treatment for HIV and aggressive B-cell lymphoma
This trial studies a lab-made immune cell treatment (CAR-T) for adults who have HIV and aggressive B-cell non-Hodgkin lymphoma that has come back or did not respond to prior treatment. It aims to see if the treatment can control the lymphoma safely in this specific group.
Duarte, CaliforniaAges 18 years+ - NCT05400824Recruiting
