Recruiting studies
- NCT07501065RecruitingPhase 4

This study tests if a steroid cream applied to the foreskin can help prevent another urinary tract infection (UTI) in uncircumcised baby boys under 6 months old who have already had one confirmed UTI.
Houston, TexasAges birth–5 months - NCT05913180RecruitingPhase 2
Vitamin C to prevent urine infections after gynecologic surgery
This Phase 2 study tests whether taking vitamin C can lower the chance of getting a urinary tract infection (UTI) after planned gynecologic surgery. It may help people who want to reduce post-surgery infection risk.
MoscowAges 18–80 - NCT06724588Enrolling by invitation
Bacteria and drug resistance in people with repeat UTIs
This study looks at bacteria in urine samples from people who get frequent urinary tract infections and have a certain type of catheter. It aims to learn why some bacteria are hard to treat and may help improve care for patients like you.
LeuvenAges 18 years+ - NCT04095572RecruitingPhase 4
Prevention options for recurring bladder infections in women
This trial studies different ways to prevent repeated bladder (urinary tract) infections in women. It may help people who keep getting these infections by testing safer or more effective prevention strategies.
BaselAges 18–70 - 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.
Jerusalem, JerusalemAges Any age - NCT04807894RecruitingPhase 4
Vaginal testosterone to prevent repeat UTIs in postmenopausal women
This study tests whether putting testosterone in the vagina can help prevent future bladder infections (UTIs) compared with a dummy treatment. It’s for older postmenopausal women who keep getting UTIs, especially those who can’t or don’t want to use vaginal estrogen.
Brooklyn, New YorkAges 60–90 - NCT04846803Recruiting
Prevent repeat UTIs using bacterial interference treatments
This trial studies a new way to help stop urinary tract infections (UTIs) from coming back by using “bacterial interference” (changing the bacteria in the urinary system). It may help people who have had UTIs keep returning despite past treatments.
Aarhus NAges 18–90 - NCT05553652Recruiting
A probiotic test for repeat bladder infections
This trial studies ASTARTE™, a probiotic, to see if it can reduce repeat urinary tract infections (UTIs). It may help people who get UTIs often by testing whether the supplement lowers how frequently they come back.
Hvidovre, CopenhagenAges 18–40 - NCT05652374RecruitingPhase 4
Gag therapy for repeat bladder infections, compared to standard antibiotics
This trial tests a therapy (called GAG therapy) to prevent repeat urinary tract infections (UTIs) in adult women. It compares how similar the results are to a well-known antibiotic standard (nitrofurantoin) to see if it works reliably.
Nijmegen, GelderlandAges 18 years+ - NCT05826067Recruiting
Testing E. coli from repeat urinary infections
This study collects and studies bacteria (E. coli) found in urine from people with urinary tract infections, including those with repeat infections. It may help improve how doctors understand these infections and choose better future treatments.
BrusselsAges 18 years+ - NCT06050148RecruitingPhase 2/Phase 3
Fecal Transplant to Prevent Repeat Urinary Tract Infections
This trial tests whether a fecal microbiota transplant (a procedure that transfers healthy bacteria from a donor's stool into your gut) can help prevent repeat urinary tract infections in women who have frequent infections.
HelsinkiAges 18–90 - NCT06261736Recruiting
Antibiotics before urethral bulking to prevent infection
This trial tests whether taking antibiotics before a urethral bulking procedure can help prevent infections. It is for people who are scheduled for this procedure and have no history of recurrent UTIs or bladder problems.
Morristown, New JerseyAges 18 years+ - NCT06409819RecruitingPhase 1/Phase 2
Phage therapy for recurrent UTIs in kidney transplant patients
This trial tests a phage (virus that kills bacteria) treatment for women who have had a kidney transplant and keep getting urinary tract infections (UTIs) caused by E. coli bacteria. It aims to see if this therapy can help prevent future infections.
La Jolla, CaliforniaAges 18 years+ - NCT04876131RecruitingPhase 4
Single IV antibiotic dose for complicated UTIs in children
This trial studies whether giving just one dose of an intravenous (IV) antibiotic can safely treat complicated urinary tract infections (UTIs) in children. It aims to see if this shorter approach works as well as standard treatment while still preventing complications.
Adelaide, South AustraliaAges 3 months–18 years - NCT06702449RecruitingPhase 1/Phase 2
UTI vaccine safety and immune response study for adults 18-64
This trial tests a new vaccine to prevent urinary tract infections (UTIs). It first checks safety and immune response in healthy adults, then in women with recent E. coli UTIs. The goal is to see if the vaccine can reduce future infections.
Lenexa, KansasAges 18–64 - NCT06719232Recruiting
Testing a new way to give bladder treatment without a catheter
This study tests a catheter-free method for delivering medication directly into the bladder. It may help patients with bladder pain, recurrent infections, bladder cancer, or cystitis after radiation or chemotherapy.
BudapestAges 18–80 - NCT06810687Recruiting
Methenamine vs. antibiotics to prevent UTIs after sling surgery
This study compares a non-antibiotic medicine (methenamine) to antibiotics for preventing urinary tract infections after a common incontinence surgery (mid-urethral sling). It may help people avoid antibiotics and their side effects.
Morristown, New JerseyAges 18–100 - NCT06907199RecruitingPhase 1
Antibiotic vs. bladder treatment plus antibiotic for recurrent UTIs
This study compares taking a daily antibiotic (nitrofurantoin) alone versus having a procedure that cauterizes bladder areas (fulguration) plus the same daily antibiotic, to see which is better at preventing recurrent urinary tract infections in women.
Kansas City, KansasAges 18–85 - NCT06940622Recruiting
D-mannose to prevent recurrent urinary tract infections in older women
This study tests whether a simple sugar called D-mannose can help prevent repeat urinary tract infections (UTIs) in postmenopausal women. If you have had frequent UTIs, this trial will see if D-mannose is a good option to keep you infection-free.
Dallas, TexasAges 55–85 - NCT07184827RecruitingPhase 3
U101 capsules to prevent recurring UTIs in women
This trial tests an oral capsule called U101 to see if it can prevent recurrent urinary tract infections (UTIs) in women who have frequent UTIs. If you've had at least 2 UTIs in the last 6 months or 3 in the last year, you may be able to join.
Kaohsiung CityAges 20–75 - NCT07186465RecruitingPhase 4
Preventing repeat bladder infections in postmenopausal women
This trial tests two approaches to prevent repeat bladder infections in postmenopausal women: a daily antibiotic pill or a vaginal tablet containing healthy bacteria and estrogen. The goal is to see which method works better over 6 months.
Bangkok, Phayatai RatchathewiAges 40 years+ - NCT07233473Recruiting
Vaginal gel for preventing repeat urinary tract infections
This trial tests a vaginal gel to see if it can prevent frequent urinary tract infections (UTIs) in women. It may help if you have had at least 4 UTIs in the past year or 2 in the past 6 months.
VilleurbanneAges 18–84 - NCT07485686Enrolling by invitation
Studying urinary tract infections to improve treatment
This study collects medical data from people with urinary tract infections (UTIs) to help future research and improve how UTIs are treated. You may be eligible if you have symptoms of a UTI now or have had them in the past.

Common questions
- Are there clinical trials for recurrent urinary tract infection?
- Yes. Clin2 currently lists 45 recruiting recurrent urinary tract infection studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a recurrent urinary tract infection trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a recurrent urinary tract infection trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
