Shanghai, Shanghai MunicipalityAges 18–65 - NCT05421364Recruiting
Boosting your own immune cells to improve the uterine lining
This study gives a small amount of your own immune cells into the uterus to change the immune environment in the uterine lining. It aims to improve how the uterine lining supports implantation, especially for people trying to conceive with embryo transfer of normal (euploid) embryos.
Sofia, SofiaAges 20–50 - NCT05421273Recruiting
Testing two spinal stimulation patterns for long-term back pain
This study compares two ways of delivering spinal cord stimulation to see which better reduces pain in people with persistent spinal pain syndrome type 2. You would be assigned to one of the stimulation “burst” patterns and followed for changes in your pain experience.
Arnhem, GelderlandAges 18–70 - NCT05421494Recruiting
Written therapy to reduce PTSD symptoms
This trial tests whether “written exposure therapy” (writing about your upsetting experience in a structured way) can reduce PTSD symptoms. It may help you feel less distressed and sleep better, depending on your situation.
Beijing, Beijing MunicipalityAges 18–65 - NCT05421650Recruiting
Surgery to remove pelvic lymph node spread in cervical cancer
This trial studies whether surgically removing cancerous pelvic or nearby lymph nodes before or as part of standard treatment improves outcomes for women with certain cervical cancers. It focuses on people whose scans suggest lymph node metastasis can be safely removed.
BengaluruAges 20–70 - NCT05424302Recruiting
Home virtual reality therapy for vestibular problems by location
This study looks at how well a home-based virtual reality (VR) vestibular therapy works for people with ongoing (chronic) balance problems, and whether results differ based on where the problem is in the inner ear. It may help your care team understand who benefits most from VR therapy.
Vancouver, British ColumbiaAges 18 years+ - NCT05424692Recruiting
Test tumor drug sensitivity to guide after-surgery colon cancer care
This study looks at whether testing a small tumor sample can identify which medicines are more likely to work for colorectal cancer after surgery. The results are used to help choose the best “after-surgery” treatment plan, when you have not had chemotherapy before surgery.
Beijing, Beijing MunicipalityAges 18–75 - NCT05427071Recruiting
Tracking a breast cancer marker to guide lymph node surgery
This study tests a special “marker” technique to help surgeons find affected lymph nodes in the armpit after chemotherapy. It may support more targeted surgery and help avoid unnecessary removal of healthy lymph nodes.
Hong KongAges 18 years+ - NCT05428228Recruiting
Hydration drink study in healthy adults
This study tests two new hydration drink formulas to see how well they rehydrate healthy adults. It’s mainly about measuring how your body responds after drinking the study products during visits.
Memphis, TennesseeAges 18–35 - NCT05432089RecruitingPhase 2
Oxytocin and therapist-client syncing during inpatient care
This Phase 2 study tests whether giving oxytocin (a hormone sometimes studied for social and bonding effects) helps patients and therapists become more “physiologically synchronized” during inpatient psychiatric care. It compares responses in patients and therapists to see if this change is measurable and potentially helpful.
Hod HaSharonAges 18–80 - NCT05433441Recruiting
Parkinson care team program for people living at home
This study tests whether “Parkinson specialized teams” can improve care for people with Parkinson’s disease who live at home, with help from a main family caregiver. It looks at whether specialized support can be followed over time and whether it helps daily functioning.
BordeauxAges 18 years+ - NCT05434065RecruitingPhase 2
Celecoxib for brain bleeding after onset
This Phase 2 trial tests whether celecoxib (an anti-inflammatory medicine) can improve outcomes after an intracerebral hemorrhage (a type of stroke caused by bleeding in the brain). It also studies how the medicine may help the body recover. You would need to start treatment quickly after symptoms begin and meet several safety and bleeding-control requirements.
TaipeiAges 20–80 - NCT05435781RecruitingPhase 4
Hydrocortisone added during stress in people on low-dose prednisolone
This study tests whether adding supplemental hydrocortisone during stressful events can prevent problems in people who develop adrenal insufficiency from long-term prednisolone. It is meant to see if “stress dosing” is safer and helps the body respond to stress.
