- NCT02740868RecruitingPhase 2
Breathing MRI using xenon gas to study lungs
This trial uses a special breathing MRI (you breathe a gas mixture) to measure how well your lungs work. It studies healthy kids and people with lung conditions like cystic fibrosis or asthma, and it may help researchers better understand lung function and flare-ups.
Toronto, OntarioAges 8 years+ - NCT02649647Recruiting
Surgery plan for rectal cancer after chemo-radiation
This trial looks at a specific type of rectal surgery after you’ve already finished chemo-radiation, aiming to remove the tumor while trying to preserve the anal sphincter (muscle control). It’s meant for people whose cancer can be safely operated on and who don’t have spread to distant organs.
Guangzhou, GuangdongAges 18–75 - NCT02598349RecruitingPhase 2
Proton radiation for pancreas cancer that can’t be removed
This trial tests proton radiation for people with pancreas cancer that cannot be fully removed by surgery (or who choose not to have surgery). It may help shrink or control the cancer using a treatment that aims to better target the tumor while limiting dose to nearby organs.
Jacksonville, FloridaAges 18 years+ - NCT02198976Recruiting
Study for adults with Barrett’s esophagus
This study looks at people age 18+ who have Barrett’s esophagus and checks for early changes that may lead to cancer. You might qualify if you can consent and are not pregnant.
Westmead, New South WalesAges 18–99 - NCT02165059Recruiting
Stomach and small-bowel tissue study during surgery
This study collects small tissue samples from the stomach and upper small intestine while you’re already having certain kinds of GI (digestive) or abdominal surgery. It aims to learn what causes stomach or bowel movement problems in some patients, which could guide future diagnosis and care.
Indianapolis, IndianaAges 6 months–90 years - NCT02732860Recruiting
Test your tumor’s drug response using a lab model
This trial grows a lab model from your own tumor tissue (or resected tissue) to predict which drugs might work best. It’s meant to match investigational treatments to your specific tumor biology.
Toronto, OntarioAges 18 years+ - NCT02674100Recruiting
Registry for pancreatic cancer patients getting a specific ablation
This is a research registry that collects information from adults with pancreatic cancer who are treated with an ablation procedure called irreversible electroporation (IRE). It may help doctors better understand which patients benefit from this approach and how the treatment is used in real life.
Birmingham, AlabamaAges 18 years+ - NCT02174549RecruitingPhase 1/Phase 2
Testing a drug with liver artery treatment for liver-spread neuroendocrine cancer
This early-stage study tests a cancer drug called tirapazamine, given along with a liver artery procedure (embolization) to treat liver-dominant metastatic neuroendocrine tumors. It aims to find a safe dose and see whether the combination can better control tumor growth in the liver.
Palo Alto, CaliforniaAges 20–99 - NCT02297217RecruitingPhase 2
Chemoradiation for advanced esophagus cancer that can’t be cured
This trial studies whether a combination of chemotherapy and radiation can help people with advanced esophageal cancer who cannot have curative treatment. It focuses on people who are having swallowing trouble and may be able to start treatment soon.
Calgary, AlbertaAges 18 years+ - NCT02869477Recruiting
Cardia cancer database study
This study collects and stores medical information from people with cardia cancer. The goal is to better understand care and outcomes over time, which may help improve future treatment planning.
Marseille, Bouches-du RhôneAges 18–95 - NCT02906943Recruiting
Testing cancer tissue to guide targeted treatment choices
This trial studies advanced solid tumors by using stored tumor samples to look for molecular clues. The goal is to help doctors better choose cancer treatments that may work for your specific tumor.
Hamilton, OntarioAges 18 years+ - NCT02454790Recruiting
Follow-up program for people with esophageal cancer
This trial tests a standard follow-up plan for people who have esophageal cancer and received a certain amount of radiation. It may help your care team monitor side effects and catch health changes early.
GroningenAges 18 years+ - NCT02691858Recruiting
Hydrocortisone for babies with bowel telescoping after air treatment
This trial looks at whether giving hydrocortisone (a steroid medicine) can improve outcomes for infants with intussusception, a condition where part of the bowel slips into another part. It specifically focuses on babies treated with a non-surgical air method to push the bowel back in place.
CairoAges 3 months–4 years - NCT02843945RecruitingPhase 1/Phase 2
Testing radiation for borderline pancreatic surgery using a tiny implant
This early trial studies whether adding targeted radiation during or around pancreatic surgery is safe and may improve outcomes for people with borderline resectable pancreatic cancer. It is mainly looking at feasibility and safety while treating close to the tumor but not spreading (no metastasis).
Tampa, FloridaAges 18 years+ - NCT02491840Recruiting
Testing lab markers that may predict chemotherapy benefit
This pilot study looks at stomach (gastric) and upper stomach/cardia cancer to find lab “markers” that could predict whether chemotherapy before and after surgery will work better. If you qualify, your tumor or blood samples may be tested to understand who benefits most from treatment.
StrasbourgAges 18 years+ - NCT02434445Recruiting
Blood and urine tests to predict kidney failure in cirrhosis
This study checks new blood and urine tests to predict who with advanced liver scarring (cirrhosis) will develop hepatorenal syndrome, a serious kidney problem. The results may help doctors spot risk earlier, especially for people being referred for a liver transplant.
Hong KongAges 18–90 - NCT02193464Recruiting
Local registry study for Crohn’s and ulcerative colitis
This study keeps a health record (a registry) of people in Daegu-Gyeongbuk with Crohn’s disease or ulcerative colitis. It helps researchers understand the illnesses in this region and improve future care planning.
DaeguAges Any age - NCT02579278Recruiting
Tests blood DNA and scans in early colon cancer surgery
This study looks at a blood test that detects cancer DNA (ctDNA) and compares it with CT scan findings before surgery. It may help doctors understand how aggressive the cancer is and how scan features relate to blood test results.
Margate, KentAges 16 years+ - NCT02423395RecruitingPhase 3
Orphenadrine for muscle cramps in people with cirrhosis
This trial tests whether orphenadrine (a medication used to reduce muscle cramping) can lessen muscle cramps in people who have cirrhosis of the liver. It may help if your cramps happen often, but you must avoid certain medication conflicts and health situations.
TantaAges Any age - NCT02298439Recruiting
Fatty liver patient registry for clinic patients
This is a research registry that collects information from people being treated for fatty liver in a specific Toronto clinic. It may help researchers better understand the illness and improve future care for patients like you.
Toronto, OntarioAges 18 years+ - NCT02495337Recruiting
Collecting tissue samples during stomach or esophagus procedures
This study collects small tissue samples from people who already need an endoscopy (EGD) and/or surgery for esophagus or stomach-related problems. The goal is to help researchers learn more about gastroesophageal cancers and related conditions.
Toronto, OntarioAges 18 years+ - NCT02883647Recruiting
Stopping antiviral treatment in chronic hepatitis B
This trial studies what happens after stopping long-term hepatitis B antiviral medicine in people whose virus has stayed controlled. It also follows patients over time to see how well they remain stable and safe after stopping.

Treatment study for Barrett’s pre-cancer or esophageal cancer
This study looks at treatment options for people with Barrett’s esophagus that has progressed to abnormal cell growth (dysplasia) or cancer. It may help doctors compare approaches that use procedures to remove and/or destroy abnormal tissue in the esophagus.
