Antibiotics right away or later for lung infections from a breathing machine
This study looks at when to start antibiotics for a lung infection you may have gotten while on a breathing machine. It compares starting them right away versus waiting for the test results to be sure you need them.

Navi Mumbai, MaharashtraAges 18–70 - NCT05922124RecruitingPhase 4
Testing two antibiotics against resistant lung and bloodstream infections
This trial studies whether cefiderocol plus ampicillin-sulbactam works better than colistin (sometimes with meropenem) for serious infections caused by carbapenem-resistant Acinetobacter baumannii (a hard-to-treat germ). It may help by finding a more effective antibiotic plan for people with these severe hospital-acquired infections.
HaifaAges 16 years+ - NCT03671967RecruitingPhase 4
Compare two antibiotics for hard-to-treat E. coli and Klebsiella bloodstream infections
This trial tests whether piperacillin-tazobactam works as well as meropenem to treat bloodstream infections caused by certain E. coli or Klebsiella germs that resist common cephalosporin antibiotics. It may help you avoid a “bigger” antibiotic if the study drug is equally effective.
Calgary, AlbertaAges 18 years+ - NCT04931225RecruitingPhase 3
Landiolol for heart-rate and circulation problems in septic shock
This Phase 3 trial tests whether landiolol (a short-acting heart-rate–lowering medicine) can improve blood circulation in adults with septic shock whose heart rate is too fast. Doctors will also check that the medication is safe in this critical-care setting.
ParisAges 18 years+ - NCT06156176Recruiting
Exercise for COVID-19 fatigue: a feasibility study
This study tests whether a personalized exercise program can help reduce fatigue after a COVID-19 infection. You'll work with a coach over video calls to see if gentle activity can improve your energy levels.
London, OntarioAges 18 years+ - NCT06731088Enrolling by invitationPhase 4
Sedation with remazolam and remifentanil for sepsis patients
This study tests a combination of two sedative drugs (remazolam besylate and remifentanil) for calming patients with sepsis who are on a ventilator in the ICU. The goal is to see if this approach improves recovery compared to standard care.
Ningbo, ZhejiangAges 18–75 - NCT06737809Recruiting
Silver-coated hip revision for infection
This trial tests a new silver-coated hip implant for people who need a revision due to a chronic infection around the joint. It may help control the infection while replacing the implant.
BerlinAges 18 years+ - NCT06736288RecruitingPhase 4
Buccalin® tablets to prevent repeat lung infections
This trial tests whether Buccalin® tablets can help adults who get frequent lower respiratory infections (like bronchitis or COPD flare-ups). It's a phase 4 study collecting more data on safety and how well the medicine works to prevent these infections from coming back.
AlessandriaAges 18–99 - NCT06730555Recruiting
HIV and hepatitis C testing for people who inject drugs
This study works with syringe service programs to see if offering opt-out HIV and hepatitis C testing helps more people get screened and connected to care. It focuses on programs that do not already offer this testing and are in high-need areas.
Miami, FloridaAges 18 years+ - NCT06728930Enrolling by invitation
New test for diagnosing latent and active TB
This study tests a new type of lab test to find TB bacteria more accurately. It is for people who are being checked for latent (hidden) TB infection, or who have just been diagnosed with active TB. The goal is to see if the new test can help doctors diagnose TB better and faster.
LondonAges 18 years+ - NCT06737406Recruiting
Cream combo for children's hand and foot warts
This trial tests a cream combination of 5-fluorouracil and calcipotriol for children with warts on their hands or feet. It may offer a more effective treatment option for stubborn warts.
Sari, MazandaranAges 4–18 - NCT06727864RecruitingPhase 3
Short-course treatment for low-risk active lung TB
This trial tests a shorter treatment course (instead of the standard 6 months) for people with low-risk active TB in the lungs. It aims to see if the shorter regimen works just as well and has fewer side effects.
New Taipei City, BangiaoAges 20–99 - NCT06731881Recruiting
Light therapy to prevent infections after sinus or nose surgery
This study tests if a special light therapy can help prevent infections after sinus or nose surgeries. The treatment is given in addition to standard care and might lower the chance of needing more antibiotics.
London, LondonAges 16 years+ - NCT06734260RecruitingPhase 3
Optimizing a two-drug therapy for H. pylori infection
This trial tests a two-drug combination (keverprazan and amoxicillin) to see if it works better for treating H. pylori, a bacteria that can cause stomach problems. It is for people who have had H. pylori before and need treatment again.
Guangzhou, GuangdongAges 18–75 - NCT06724640RecruitingPhase 1
Safety study of an experimental HIV prevention drug in healthy adults
This study tests a new injectable drug (VH4011499) for safety and how the body processes it. It's for healthy adults without HIV, and participants will get either the study drug or a placebo (an inactive shot).
Las Vegas, NevadaAges 18–55 - NCT06723392RecruitingPhase 3
Treating bladder bacteria in pregnancy to prevent infections
This trial tests if a common antibiotic can safely treat bacteria in the urine of pregnant women who have no symptoms, to see if it prevents later infections. It focuses on women in low- and middle-income countries.
Dhaka, BangladeshAges 18–49 - NCT04910464RecruitingPhase 3
Tranexamic acid trial for adults with sepsis in ICU
This trial studies whether early tranexamic acid (a medicine that can reduce bleeding) can change the body’s inflammatory response in people with sepsis. If it works, it may help improve outcomes for certain ICU patients—but you must meet specific safety and eligibility checks.
AsyutAges 18–65 - NCT06726395RecruitingPhase 4
Comparing two antibiotics for staph bloodstream infection
This trial compares two antibiotics, cloxacillin and benzylpenicillin, to see which works better for patients with a bloodstream infection caused by a specific type of staph bacteria that responds well to penicillin. It may help guide more effective treatment.
LundAges 18 years+ - NCT06721169Recruiting
Phenol or laser for pilonidal sinus?
This trial compares two minimally invasive treatments for pilonidal sinus, a small tunnel under the skin near the tailbone. It aims to find which option works best with less pain and faster recovery.
MersinAges 18 years+ - NCT06717594Recruiting
Study of antibiotics for resistant infections
