Shanghai, Shanghai MunicipalityAges 18 years+ - NCT04399707Recruiting
Nerve-pain device study for pain after C-section
This study tests whether a small skin electrical nerve stimulator (called TENS) can reduce pain after a planned or not-urgent C-section. You may be more likely to have less pain and use fewer pain medicines if the TENS helps you.
Honolulu, HawaiiAges 18 years+ - NCT04504006Recruiting
Tracking surgery choices for lymph node spread in endometrial cancer
This is an observational study that follows people with endometrial cancer who have had surgery to check and remove pelvic (and sometimes paraaortic) lymph nodes. It looks at how different surgical approaches and any added treatment affect local control (keeping cancer from coming back in the pelvis/nearby areas).
Essen, North Rhine-WestphaliaAges 18 years+ - NCT04549935RecruitingPhase 4
Testing eye drops and procedures after two-eye surgery
This Phase 4 study looks at a treatment plan around the time of planned surgery on both eyes (called RLE). It may help the researchers learn how safe and effective the approach is for improving eye outcomes after surgery.
Bozeman, MontanaAges 22–75 - NCT04704297RecruitingPhase 4
Trigger point shots for low back muscle pain
This trial tests whether injecting sore “trigger points” in low back muscles helps improve chronic low back pain. It compares treatments in people with specific low back muscle pain patterns and excludes several other causes of pain.
Tacoma, WashingtonAges 18 years+ - NCT04669873Recruiting
Partial breast radiation vs whole breast radiation after lumpectomy
This trial studies whether treating only part of the breast with radiation works as well as treating the whole breast in people with early breast cancer after lumpectomy. It may help reduce radiation exposure to healthy tissue, while still controlling the cancer.
São Paulo, São PauloAges 50–90 - NCT04126876RecruitingPhase 2
IMO-2125 skin injection for thick, early-stage melanoma
This trial tests whether an injection given into the skin (IMO-2125) can improve outcomes for people with thicker primary melanoma that has not spread to lymph nodes or other organs. Participants also have planned surgery to remove the tumor and check a sentinel lymph node.
AmsterdamAges 18 years+ - NCT04206748Recruiting
Remote glucose monitoring for diabetes during pregnancy
This study tests whether a remote glucose monitoring device, used alongside your usual glucose meter, can help manage blood sugar during pregnancy. It may be helpful if you have gestational diabetes or type 2 diabetes in pregnancy and can start before about 30 weeks.
Houston, TexasAges 18 years+ - NCT04722900Recruiting
Study of children born to mothers with gestational diabetes
This study looks at children whose mothers did or did not have gestational diabetes during pregnancy. It will help researchers understand possible differences in children and how pregnancy diabetes may affect them.
TübingenAges 6–17 - NCT03094429RecruitingPhase 2/Phase 3
Testing NaBen add-on to clozapine for tough schizophrenia symptoms
This trial tests whether adding NaBen (a supplement-like medicine) to clozapine can improve “residual” symptoms in adults with difficult-to-treat schizophrenia. The study also checks safety and the best dose, using a placebo (inactive pill) for comparison.
Pasadena, CaliforniaAges 18–55 - NCT04312412Recruiting
Follow-up of treatment for finger tendon injuries
This study looks at outcomes—how well treatment works—after injuries to the finger or thumb flexor tendons. If your injury happened in a certain location of the tendon and you meet other safety criteria, your care and results may help improve future treatment.
