Shanghai, Shanghai MunicipalityAges 18–90 - NCT05901428RecruitingPhase 3
Check if two breast cancer treatments work better after surgery
This trial compares two treatment approaches in people with high-risk hormone-positive, HER2-negative breast cancer that has spread to certain lymph nodes. It looks at which option works best to lower cancer returning and to control the disease after surgery and initial chemotherapy.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05904145Recruiting
Study of mother and baby health during early pregnancy
This study follows pregnant women to better understand health needs for mothers and newborns, starting in the first part of pregnancy. You may be able to join if you live nearby, are at least the required age, and your pregnancy is confirmed to be under 20 weeks.
KintampoAges 15 years+ - NCT05893511RecruitingPhase 3
EUS drainage versus antibiotics for high-risk gallbladder inflammation
This Phase 3 study compares two approaches for people with gallstone-related acute gallbladder inflammation: a procedure called EUS drainage versus antibiotic treatment alone. It may help you avoid early surgery if you are considered high risk for immediate gallbladder removal.
Hong Kong, HONG KONGAges 18 years+ - NCT05895136RecruitingPhase 2
Albumin plus blood thinner for severe cirrhosis after hospital recovery
This Phase 2 trial tests whether giving albumin together with enoxaparin (a blood thinner) can improve outcomes for people hospitalized with decompensated cirrhosis who are at high risk. It may help your recovery after certain serious liver-related complications and reduce the chance of poor outcomes.
ClichyAges 18–80 - NCT05898594Recruiting
Lung cancer screening for high-risk Black adults
This study is designed to help Black adults at higher risk get lung cancer screening. It checks whether a screening approach can catch lung problems early and connect people to the right next steps.
Chicago, IllinoisAges 50–80 - NCT05909046Recruiting
Diabetes screening after childbirth and follow-up care study
This study checks how well diabetes screening done right after delivery works, and then offers follow-up care for participants later after birth. It may help you catch ongoing diabetes risk early and connect you to the right care.
Columbus, OhioAges 18 years+ - NCT05906407Recruiting
Genetic-guided treatment planning for high-risk early breast cancer
This study uses tumor genetic testing to help plan more precise treatment for people with early high-risk breast cancer. You may be asked to give a recent tumor sample so researchers can match your cancer features with the best available options.
AugsburgAges 18–80 - NCT05890716Recruiting
AI analyzes your ECG to help in high-risk heart rhythm cases
This trial uses an AI program to review ECG heart-tracing data collected from short-term monitoring devices. It aims to see whether the AI can better detect concerning heart rhythm patterns in people who are high risk for heart rhythm or heart problems.
Groningen, Provincie GroningenAges 4 years+ - NCT05852223RecruitingPhase 2
Pembrolizumab for high-risk thyroid cancer that cannot be fully removed
This study tests pembrolizumab (an immune therapy) in people with high-risk thyroid cancer that is hard to treat with surgery alone. It looks at whether this drug can reduce persistent or recurrent cancer after your planned treatment.
Pavia, LombardyAges 18 years+ - NCT05862558Recruiting
Lithotripsy to open blocked, calcified artery for TAVR
This trial tests whether a treatment called intravascular lithotripsy (using sound waves from inside a blood vessel) can help widen severely calcified, narrowed iliac arteries so a TAVR procedure can be done through the groin. It may help some people who are considered “high risk” for access, based on CT scan findings.
Plano, TexasAges 18–90 - NCT05837884Recruiting
