Chewing gum and cold water gargle after lung breathing tube procedure
This study tests whether chewing gum and gargling with cold water can reduce sore throat and other discomfort after a bronchoscopy—a procedure where doctors look inside your airways with a thin camera. If it works, it could be a simple, safe way to feel better after the procedure.

Seville, SevillaAges 14 years+ - NCT07516236Recruiting
Using blood oxygen levels to guide fluid treatment in septic shock
This trial is studying whether a measure of oxygen in your blood (called SvO2) can help doctors decide if giving you more fluids will help improve your blood pressure during septic shock. The goal is to make fluid treatment more precise and avoid giving too much fluid.
MenoufAges 18 years+ - NCT05054257RecruitingPhase 1
CAR T19 for hard-to-treat blood cancers that have CD19
This Phase 1 study tests CAR T cells designed to attack cancer cells that carry a marker called CD19. It’s for adults with certain relapsed or treatment-resistant B-cell leukemias (ALL) or lymphomas (NHL) where other treatments may not have worked.
PragueAges 18–80 - 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 - NCT07515885Recruiting
Electroacupuncture for Shingles Pain Relief
This study tests whether electroacupuncture (a form of acupuncture with mild electrical stimulation) can reduce pain from shingles (herpes zoster), a viral infection that causes painful skin rashes. Researchers will also measure certain markers in your blood to understand how the treatment works.
Hangzhou, ZhejiangAges 20–80 - NCT07512596RecruitingPhase 2
Study of a new antibiotic for hospital pneumonia from resistant bacteria
This trial tests a drug called Polymyxin E2 Methanesulfonate for a serious lung infection that patients can get in the hospital, caused by bacteria that don't respond to common antibiotics. It may be an option for people on ventilators or recently hospitalized with pneumonia that standard drugs can't treat.
Bengbu, AnhuiAges 18 years+ - NCT07511218RecruitingPhase 1
Study of AHB-171 for stable chronic hepatitis B
This trial tests a new investigational drug called AHB-171 for people with chronic hepatitis B who are already stable on standard antiviral therapy. It aims to see if the drug is safe and may help control the virus better.
Ch’ang-ch’un, JilinAges 18–65 - NCT07508839Recruiting
Probiotic lozenge study for healthy adults
This trial tests a probiotic lozenge (a dissolvable tablet) to see if it's safe and works well. It's for healthy adults who don't smoke and are between 18 and 70 years old.
Hamilton, OntarioAges 18–70 - NCT07512167Recruiting
Predicting tetanus survival outcomes using severity scores
This study helps doctors better predict which tetanus patients are at highest risk of dying in the hospital. Researchers will use special scoring systems to identify the most severe cases early so treatment can be adjusted.
Cairo, Cairo GovernorateAges 18 years+ - NCT07515989Recruiting
Testing a nerve biopsy method to diagnose leprosy
This study tests a new way to diagnose leprosy by taking a tiny sample from a nerve under the skin using ultrasound guidance. The goal is to see if this method can accurately detect leprosy and help doctors know when treatment is working.
