Study blood sugar and pregnancy outcomes after weight-loss surgery
This study looks at how blood sugar and related markers change during pregnancy after weight-loss surgery (gastric bypass or sleeve). It also compares pregnancy outcomes, to help understand what to expect and how to monitor you during pregnancy.
AalstAges 18–45 - NCT05108519Recruiting
Study of side effects and response to anti-VEGF treatments
This study looks at the side effects (complications) and how well people respond when they receive anti-VEGF cancer medicines. It may help doctors better manage treatment and understand who benefits most.
Houston, TexasAges Any age - NCT05100940Recruiting
Study after a heart procedure complication
This trial looks at what happens after complications during or after a heart procedure called coronary angiography or PCI. It may help improve care and outcomes for people who experience a problem during treatment.
Minneapolis, MinnesotaAges 18 years+ - NCT02851758Recruiting
Autologous mitochondria treatment for critically ill heart children on ECMO
This trial looks at giving a child their own mitochondria to help protect the heart from injury caused by reduced blood flow. It is for children with serious heart problems who are on a heart-lung machine and may have signs of ischemia (reduced blood flow damage).
Boston, MassachusettsAges Up to 17 years - NCT04303702Recruiting
Oxytocin during late labor to study childbirth changes
This study looks at how oxytocin, a medication that helps labor contractions, affects the second stage of labor. It may help researchers understand what leads to safer and smoother delivery for first-time mothers.
St Louis, MissouriAges Any age - NCT04973397Recruiting
Preventing vascular complications during same-day non-heart surgery
This study looks at ways to reduce blood vessel–related problems (like stroke or heart strain) around the time of planned same-day, non-heart surgery. If you qualify, you may be asked to take part in a specific prevention plan during and around your operation.
Winston-Salem, North CarolinaAges 45 years+ - NCT04959526Recruiting
Testing lung stiffness and breathing function in healthy adults
This study compares a lung ultrasound method (shear-wave elastography) with breathing function tests to see how well they match. It may help researchers better understand how to measure lung health using imaging versus breathing tests.
Rochester, MinnesotaAges 18 years+ - NCT04940780Recruiting
Integrative symptom care during ongoing cancer treatment
This trial offers an integrative therapy program aimed at helping people with symptoms while they are actively receiving cancer treatment. It may help by combining supportive treatments over 8 weekly visits, but you must be able and willing to attend them all.
JerusalemAges 18 years+ - NCT04909606Recruiting
Nurse coaching to prevent steroid treatment complications
This study tests a nurse-led program to help prevent complications from taking corticosteroids (steroid medicines) for a long time. If you’ve recently started high-dose steroid treatment, this could offer structured support to reduce risks.
BrestAges 18 years+ - NCT04901234RecruitingPhase 2
Adaptive radiation for advanced throat cancer
This study tests an approach called “adaptive radiotherapy,” where the radiation plan may be adjusted based on how your tumor and anatomy look during treatment. It is for adults with biopsy-proven oropharyngeal (throat) squamous cell carcinoma who are planning curative radiation, with or without chemotherapy.
MelbourneAges 18 years+ - NCT04915261RecruitingPhase 4
Lenient versus strict instructions after heart device surgery
This trial compares two styles of “post-surgery instructions” after implantation of a new heart device lead. It may help determine which approach is better for patients’ recovery and safety after the procedure.
Ottawa, OntarioAges Any age - NCT04783441Recruiting
Continuous glucose sensor study after kidney transplant
This study checks whether using a continuous glucose monitor (a sensor that tracks sugar throughout the day) is helpful and practical for people with a recent kidney transplant and type 2 diabetes on insulin. You may need to wear the sensor continuously and still do finger-stick glucose checks for safety.
Sacramento, CaliforniaAges 18 years+ - NCT04848844Recruiting
Congenital heart disease transplant registry study for adults
This study collects and shares anonymous information about adults being considered for a heart transplant because of a congenital (from birth) heart problem or an inherited heart muscle condition. The goal is to better understand these patients and support research that may improve care.
Hamburg, Free and Hanseatic City of HamburgAges 18 years+ - NCT04821154Recruiting
Testing outcomes after revision knee replacement with a Persona system
This study looks at how well a specific revision knee replacement system (the Persona system) works after earlier knee problems or surgeries. You may be eligible if you need a revision knee and can follow follow-up care instructions; the trial also checks for certain infection, bone, and health-safety factors.
Fayetteville, ArkansasAges 18 years+ - NCT02493478Recruiting
Improve safety during placing breathing tubes in children
This trial looks at ways to improve the safety and quality of emergency breathing tube placement in pediatric critical care and emergency settings. It may help reduce complications and improve how clinicians do these urgent procedures.
Birmingham, AlabamaAges Any age - NCT04623424Recruiting
Study gut bacteria during stem cell transplant
This study looks at changes in your gut bacteria (microbiome) around the time of stem cell transplant. The goal is to understand how these bacteria relate to transplant outcomes, which may help doctors improve care in the future.
Detroit, MichiganAges 18–80 - NCT04669886Recruiting
Blood test before kidney stone surgery to predict infection risk
This study looks at a blood test done before percutaneous nephrolithotomy (PCNL), a procedure to remove kidney stones. The goal is to see whether results can predict who is more likely to develop infections or strong whole-body inflammation after surgery.
Miami, FloridaAges 18 years+ - NCT04433676Recruiting
Tracking early nausea after surgery in Sweden
This study collects information from patients who have surgery to better understand and prevent postoperative nausea and vomiting (feeling sick or throwing up after anesthesia). By joining, you help researchers learn how to reduce these side effects.

Long-acting tacrolimus after lung transplant
This early-stage study tests a long-acting form of tacrolimus (a common anti-rejection medicine) soon after lung transplant. It aims to see if it can be used safely and effectively for people receiving lung transplants at Vanderbilt (VUMC).
Nashville, TennesseeAges 18 years+ - NCT04390230Recruiting
Who can use the scrotal pump on their inflatable penile implant?

Common questions
- Are there clinical trials for complication?
- Yes. Clin2 currently lists 1,080 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.
