Recruiting studies7,890 total
- NCT05092373RecruitingPhase 1

This Phase 1 study tests whether a tumor treating fields device works better when added to standard cancer drugs. It may help people with advanced solid tumors in the chest or belly, especially when standard treatment didn’t work or can’t be tolerated.
Houston, TexasAges 18 years+ - NCT05093881Recruiting
Follow-up study for people treated for alcoholic liver scarring
This study checks on people who previously received Cellgram-LC for alcohol-related liver cirrhosis (liver scarring) in an earlier trial. It helps researchers learn long-term safety and outcomes after that treatment.
Bucheon-siAges Any age - NCT05093907RecruitingPhase 1/Phase 2
Testing a new cancer drug plus capecitabine for metastatic colon cancer
This trial studies whether BEY1107, a new treatment, is safe and works better when combined with capecitabine in people with metastatic colorectal (colon/rectum) cancer. It is aimed at cancers that have already progressed after standard chemotherapy.
Seoul, Jongro-goAges 19 years+ - NCT05093231RecruitingPhase 2
Pembrolizumab plus olaparib for stage 4 pancreatic cancer
This trial tests whether combining pembrolizumab (an immunotherapy) with olaparib (a DNA-repair drug) can work better for people with metastatic (stage 4) pancreatic cancer. It targets tumors with certain lab marker results and aims to improve control of cancer growth.
MelbourneAges 18 years+ - NCT05095532RecruitingPhase 1
TP-IAT transplant with your own cells for type 1 diabetes
This early-stage study tests whether adding your own special cells (mesenchymal stromal cells) at the same time as a TP-IAT transplant can improve diabetes outcomes. It may help people who are already planning TP-IAT, but it is only for certain age, diabetes, and health criteria.
Charleston, South CarolinaAges 18 years+ - NCT05095714Recruiting
Fast MRI for close monitoring of high-risk liver cancer
This trial studies a faster MRI scan to help track early liver cancer in people who have cirrhosis and are considered high risk. It may improve how often and how well doctors can look for changes without using longer imaging sessions.
BondyAges 18 years+ - NCT05097872Recruiting
Diet trial for IBS with non-constipation symptoms
This study tests whether a specific diet plan can improve symptoms in people with IBS that is not constipation (IBS-D or IBS-M). If you qualify, you’ll complete symptom questionnaires and follow the study diet for the trial period to see if symptoms improve.
LeuvenAges 18–70 - NCT05099939Recruiting
Monitoring sugar changes in adults with cystic fibrosis
This study uses continuous glucose monitoring (a sensor that checks blood sugar trends) to understand how sugar handling changes over time in people with cystic fibrosis. It may help doctors spot early “pre-diabetes” or abnormal sugar patterns sooner.
Montreal, QuebecAges 18 years+ - NCT05101382Recruiting
Study of colorectal cancer records to improve future research
This retrospective study uses existing colorectal cancer imaging and/or preserved tissue samples to support more precise (personalized) research. It may help researchers better understand colorectal cancer over time, but it does not involve new treatment.
Genova, GEAges 18 years+ - NCT05102110Recruiting
Check rectal mucus in people with throat or lung cancers
This study looks at a substance called rectal mucus during an exam to learn about changes in people with cancers of the throat/airways (aero-digestive tract). It’s a feasibility study, meaning it mainly tests whether this approach is safe and practical.
ExeterAges 18–99 - NCT05107674RecruitingPhase 1
Early drug study for advanced cancers that have limited options
This Phase 1 study tests NX-1607 in adults with advanced cancers that are hard to treat with standard care. It focuses on safety and early signs of how well the drug may work in specific cancer types.
Duarte, CaliforniaAges 18 years+ - NCT05108896Recruiting
Testing breathing and swallowing recovery after ICU breathing support
This study looks at aspiration (food or liquid going “the wrong way” into the airway) in people who survived a serious ICU breathing problem. It may help doctors better support safe swallowing and breathing recovery after being on a breathing machine.
Stanford, CaliforniaAges 18 years+ - NCT05110144RecruitingPhase 2
Testing two doses of two nerve pain medicines for chronic cough
This Phase 2 study tests whether two doses of duloxetine and amitriptyline can reduce symptoms in people with chronic cough that hasn’t responded to usual care. You may join to see if these medicines lessen cough severity over an 8-week blinded treatment period.
Rochester, MinnesotaAges 18–75 - NCT05112328Recruiting
Pancreatic enzyme added to feeding for ICU adults
This study tests whether adding pancreatic digestive enzymes to tube feeding can improve digestion and outcomes in critically ill adults who have higher risk of not producing enough digestive enzymes. If you qualify, you may receive the enzyme supplement or a comparison treatment while you’re in the ICU.
Seoul, Jongno-guAges 18 years+ - NCT05113095Recruiting
Survey of Darvadstrocel in Crohn’s with fistulas
This is a survey study in people with Crohn’s disease who have complex perianal fistulas and have already received Darvadstrocel. It aims to understand how patients are doing after treatment and gather real-world feedback.
Tokyo, TokyoAges 20 years+ - NCT05117723Recruiting
IPMN cyst database to help predict pancreatic cancer risk
This study collects information from people who have an IPMN cyst in the pancreas to help predict who may be at higher risk of pancreatic cancer. It may help your care team estimate risk and plan follow-up more effectively.
Fitzroy, VictoriaAges 18–90 - NCT05120752RecruitingPhase 3
Low FODMAP diet trial for IBS without lactose intolerance
This trial tests whether eating a low-FODMAP diet can reduce IBS symptoms in people who do not have lactose intolerance. It aims to improve moderate-to-severe IBS symptoms by changing what kinds of carbohydrates you eat.
Jette, Brussels CapitalAges 18–75 - NCT05126290Recruiting
Study for CTNNA1 gene family members
This study looks at people who carry a specific “loss-of-function” CTNNA1 gene change—or who are closely related to someone who does. It’s designed to better understand this genetic risk in families and may help guide future care and monitoring.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05128890Recruiting
People who had prior pancreatic or liver surgery
This study looks back at people who previously had surgery to remove part of the pancreas or liver at a specific hospital. It aims to compare different resection (removal) techniques and how patients did afterward.
Dallas, TexasAges 18 years+ - NCT05129605Recruiting
Prostate cancer genetic risk screening study for men
This study looks at your personal and family risk for prostate cancer and helps decide who should have extra screening like MRI. It may help you find cancer earlier if you are at higher genetic risk.
Boston, MassachusettsAges 35–74 - NCT05132244Recruiting
Checking and treating blood sugar in pancreatic cancer
This trial tests a plan to monitor and manage blood sugar in people with pancreatic ductal cancer who are starting a specific chemotherapy regimen (FOLFIRINOX). The goal is to prevent or address high blood sugar during treatment, which may help people stay on therapy safely.
Vancouver, British ColumbiaAges 18 years+ - NCT05132504RecruitingPhase 2
Pre-surgery chemotherapy and immunotherapy for operable pancreatic cancer
This Phase 2 trial tests giving chemotherapy plus pembrolizumab (an immunotherapy) before surgery, to shrink or control potentially removable pancreatic cancer. The goal is to improve outcomes while making sure the cancer can still be safely removed by surgery.
Houston, TexasAges 18 years+ - NCT05132816Recruiting
Test manometry after partial anti-reflux surgery
This study checks how well a swallowing test called high-resolution manometry works after partial anti-reflux surgery. It focuses on adults with certain abnormal esophagus muscle patterns to help doctors understand what to expect after the operation.
Schlieren, Canton of ZurichAges 18 years+ - NCT05133102Recruiting
Collecting saliva to study Barrett’s esophagus over time
This study collects saliva (and, for some people, looks at stomach/esophagus samples) to understand how the mouth and gut “microbiome” changes over time in people with Barrett’s esophagus. It may help researchers find patterns that relate to Barrett’s esophagus and future risk.
