Recruiting studies
- NCT03643718Recruiting
Emergency surgery and trauma patient registry online
This trial is a web-based registry that collects information about people who need emergency surgical or non-surgical treatment for sudden (acute) problems. Your information can help doctors better understand and improve emergency care and decision-making.
PisaAges Any age - NCT03667027Recruiting
Study of breathing muscle and lung changes during transplant planning
This trial studies how the diaphragm (your main breathing muscle) and lung/airway tissue behave in people who are being supported until they can get a lung transplant. The results may help doctors better understand breathing failure and improve transplant care.
TorontoAges 18 years+ - NCT03716089Recruiting
Laparoscopic surgery for stomach GIST by tumor site
This trial studies whether doing laparoscopic surgery for stomach GISTs (gastrointestinal stromal tumors) works and is safe when the tumor is in a “favorable” versus “unfavorable” location. You might be eligible if your tumor is confirmed as GIST and doctors expect to remove it completely using keyhole surgery.
Fuzhou, FujianAges 18–75 - NCT03793517RecruitingPhase 2/Phase 3
Decitabine plus chemotherapy before stem cell transplant for high-risk leukemia
This trial studies whether adding decitabine plus chemotherapy before a stem cell transplant can better control “minimal residual disease” (very small amounts of leukemia left behind) in certain high-risk acute leukemia types. It may help reduce the chance of the leukemia coming back after transplant.
Beijing, Beijing MunicipalityAges 18–55 - NCT03818334RecruitingPhase 2/Phase 3
Cyclophosphamide after transplant for blood cancer without sibling donor
This trial studies giving cyclophosphamide after a stem cell transplant when there is no matched sibling donor, but a well-matched unrelated donor is available. It aims to improve outcomes for people with blood cancers undergoing this transplant.
São Paulo, São PauloAges 1–75 - NCT03819296RecruitingPhase 1
Fecal transplant to treat cancer immunotherapy bowel side effects
This early-phase study tests whether changing your gut bacteria with a fecal transplant can improve diarrhea or colitis caused by cancer immunotherapy. It may help people whose symptoms have not fully settled with standard treatments like steroids and other immune-blocking medicines.
Houston, TexasAges 18 years+ - NCT03848962Recruiting
Share leftover or collected samples for research
This study helps collect and share human samples (like blood or other specimens) so researchers can do new studies. It’s mainly about providing samples for research use, not testing a treatment on you.
Huntsville, AlabamaAges 1 month–89 years - NCT03901924Recruiting
Ventilator settings to protect the breathing muscle
This study looks at a specific way to control a breathing machine (ventilator) to help prevent weakness of the diaphragm, the main breathing muscle, in newly intubated adults. You might be considered if you are newly on a ventilator for less than 36 hours and certain other conditions are not present.
Chicago, IllinoisAges 18 years+ - NCT03945968Recruiting
Risk scores after abdominal surgery for people with health conditions
This study looks at how other health problems affect the chance of postoperative complications after abdominal surgery. It aims to help doctors better predict risk and decide on the safest care for you.
ArkhangelskAges 18 years+ - NCT03948048Recruiting
ECMO timing study for children with hard-to-treat septic shock
This trial looks at whether and when a heart-lung machine called ECMO should be used in children whose septic shock is not responding to standard treatment. It may help doctors choose the best timing to improve survival and recovery in the PICU.
ShanghaiAges 4 weeks–18 years - NCT04037995Recruiting
Real-world study of advanced liver disease in China
This study looks at people with very advanced liver problems to better understand what happens in real life. It may help doctors improve care for advanced cirrhosis and certain liver cancers.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT04053439Recruiting
Testing blood-clone risk to prevent chemotherapy complications
This study looks at a specific genetic/production change in blood-forming cells (“clonal hematopoiesis”) to understand who is more likely to have complications from lymphoma chemotherapy. It may help doctors predict risk and possibly reduce harmful side effects.
Toronto, OntarioAges 60 years+ - NCT04067830RecruitingPhase 2
Breathing muscle training before lung surgery to prevent complications
This trial tests whether training your breathing muscles before lung surgery can reduce lung problems after surgery in people with stage I to IIIb lung cancer. It may help improve breathing and lower the chance of post-surgery lung complications.
Buffalo, New YorkAges 18 years+ - NCT04068012Recruiting
Test of a decision support tool for children with PARDS
This trial tests a computer “decision support” tool to help the care team manage treatment for children with PARDS who are just starting a breathing machine. It may help clinicians choose care steps and potentially support safer, more effective breathing management during the first days of ventilation.
Chicago, IllinoisAges 1 month–18 years - NCT04084938Recruiting
Clot-blocking treatment versus surgery for enlarged prostate
This trial compares artery embolization (blocking blood flow to the prostate) with standard surgery for urinary symptoms caused by an enlarged prostate. It may help patients who have moderate-to-severe bladder outlet symptoms and are looking for a treatment option when medicine didn’t work (or they don’t want medicine).
OsloAges Any age - NCT04164173Recruiting
Breathing therapies after heart surgery for lung overinflation
This study looks at breathing (respiratory) therapies to help after certain heart surgeries that can cause the lungs to feel overly inflated. If you’re eligible, you may receive and be assessed for how well these breathing treatments work during your recovery.
Dallas, TexasAges 18–80 - NCT04205370Recruiting
Study sleep habits during pregnancy
This study looks at sleep behaviors (how you sleep and rest) during pregnancy. The researchers want pregnant patients to answer questions and/or use a phone to help them better understand sleep patterns in late pregnancy.
Ann Arbor, MichiganAges 18 years+ - NCT04209218Recruiting
Blood pressure and dexamethasone during lung cancer surgery
This study looks at how best to manage blood pressure during lung cancer surgery and whether giving dexamethasone (a steroid medicine) helps patients during the operation and recovery. You might benefit if you’re having longer lung cancer surgery and your heart and other organs are stable enough for the study.
Beijing, Beijing MunicipalityAges 50–90 - NCT04242069Recruiting
Lifestyle coaching for overweight women trying to conceive
This trial tests a lifestyle program (using a smartphone) to help overweight women improve health before pregnancy while trying to conceive within the next year. It may help you and your partner build healthy habits before pregnancy.
Québec, QuebecAges 18–40 - NCT04266223Recruiting
Head and neck mask monitoring during radiation to improve setup
This trial tests a surface-monitoring technology that checks a head-and-neck radiation “positioning mask” during treatment. It may help the radiation team make sure the mask and patient are aligned correctly for safer, more accurate therapy.
Blacktown, New South WalesAges 18 years+ - NCT04273607RecruitingPhase 2/Phase 3
Test an ECMO approach without blood thinners for lung failure
This trial studies whether people on a breathing machine called VV-ECMO can be managed without routine blood thinners, to reduce bleeding risk. It is meant for adults with severe lung failure (ARDS) and checks that it is safe for you to avoid anticoagulation.
Toronto, OntarioAges 18 years+ - NCT04303702Recruiting

Common questions
- Are there clinical trials for complication?
- Yes. Clin2 currently lists 1,145 recruiting complication 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 complication 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 complication 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.
