Multi-point full-thickness biopsy to confirm complete rectal cancer response
This trial checks whether taking small samples from the full thickness of rectal tissue can accurately confirm that rectal cancer has fully responded to chemotherapy and/or radiation. It may help doctors decide the best next step if no tumor is seen after treatment.
Beijing, Beijing MunicipalityAges 18–80 - NCT04800458Recruiting
Testing antibody findings to confirm autoimmune low platelets
This study looks at blood test antibodies to help confirm whether low platelet counts are caused by an autoimmune condition. It may help doctors better classify your type of low platelets and guide appropriate next steps.
PessacAges 18 years+ - NCT04809025Recruiting
Testing biopsy samples vs surgery samples for stomach cancer testing
This study compares two ways of getting stomach cancer tissue: a camera-guided biopsy and a tissue sample taken during planned stomach surgery. The goal is to see which sample better supports molecular (gene-based) testing to guide diagnosis.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT04815005Recruiting
Registry study for people with HoFH
This study is a registry (a list that collects health information) for people with homozygous familial hypercholesterolemia, a genetic cholesterol condition. It helps researchers understand this condition better and connect patients with future research.
Philadelphia, PennsylvaniaAges Any age - NCT04846712Recruiting
Ultrasound to check how severe a new ankle sprain is
This trial studies whether an ultrasound scan can help doctors judge how severe a first-time ankle sprain is. It may help guide treatment and follow-up for people whose sprain affects work or sports.
Saint-EtienneAges 18–60 - NCT04846933Recruiting
Testing extra scans and data to guide ovarian cancer treatment
This trial collects information from people with suspected ovarian cancer and uses it to improve diagnosis and help predict which treatments may work. It may also look for targeted options, based on scan and medical data results.
TurkuAges 18 years+ - NCT04850053Recruiting
Using brain-related “seeds” to help diagnose Alzheimer’s disease
This study looks for specific markers (“seeds”) that may help doctors diagnose Alzheimer’s disease and distinguish it from other memory or thinking conditions. If you are in the right age range and can complete memory testing and provide a sample, you may help validate a diagnostic approach.
Beijing, Beijing MunicipalityAges 55–75 - NCT04867915Recruiting
Study of CLL, SLL, and related blood conditions in Italy
This is a study that looks back and forward at people diagnosed with chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), or a related early condition called MBL. It aims to improve how these conditions are recognized and managed over time in Italy.
AlessandriaAges 18 years+ - NCT04880200Recruiting
HIV testing at the clinic with help getting care
This study tests point-of-care lab tests that can find HIV-related virus levels quickly, and adds support to help people stay on treatment and connect to prevention services. If you are already HIV-positive and coming in for same-day lab testing, you may be able to get extra help with follow-through.
