Cleveland, OhioAges 18–90 - NCT04546399RecruitingPhase 2
Blinatumomab with or without nivolumab for first relapse ALL
This study compares blinatumomab alone versus blinatumomab plus nivolumab in young people whose B-cell ALL has returned for the first time. It aims to see whether adding nivolumab improves control of the leukemia after relapse.
Birmingham, AlabamaAges 1–30 - NCT04511013RecruitingPhase 2
Trial for BRAF-mutant melanoma spread to the brain
This Phase 2 study tests whether a 3-drug plan (encorafenib + binimetinib + nivolumab) works better than ipilimumab + nivolumab for melanoma that has spread to the brain. If you qualify, you’ll get either treatment and have frequent brain scans to track how well it controls the tumors.
Birmingham, AlabamaAges 18 years+ - NCT04529785Recruiting
Tested added ethanol vein treatment during repeat atrial fibrillation ablation
This trial compares two ways to help stop atrial fibrillation during a repeat procedure: standard vein isolation only versus standard isolation plus an added medicine (ethanol) into the vein of Marshall. It aims to see whether the added step improves results when atrial fibrillation returns after a previous successful treatment.
Bruges, Please SelectAges 18 years+ - NCT04525989Recruiting
Short-course proton vs photon radiation before rectal surgery
This study compares two types of pre-surgery radiation—protons versus standard photons—in people with high-risk rectal cancer. The goal is to shrink and control the tumor while safely getting you ready for surgery, and to see which approach works better.
Stockholm, SolnaAges 18 years+ - NCT04458584Recruiting
Thumb surgery trial comparing treatments for basal joint arthritis
This study looks at how well different thumb (basal joint) surgery approaches restore strength and function. You would be having planned (non-replacement) thumb surgery, and your chosen surgeon would care for you while researchers compare outcomes.
Lebanon, New HampshireAges 21 years+ - NCT04429217Recruiting
Immediate versus delayed weight-bearing after ankle surgery
This trial compares two rehab plans after ankle fracture surgery: putting weight on the ankle right away versus waiting. It aims to see which approach is safer and better for healing and recovery.
LuganoAges 18–70 - NCT04432012RecruitingPhase 4
Compare steroid shots versus other delivery after knee replacement
This study compares different ways of giving steroid medicine after a total knee replacement to see which approach works best and is well-tolerated. You may qualify if you’re getting a first (not repeat) knee implant and can follow the study steps.
LuganoAges 50–85 - NCT04375033RecruitingPhase 4
Comparing Buprenorphine pill vs injection for opioid use disorder
This study compares two forms of a medication called buprenorphine (one is a pill you take under the tongue, the other is an injection) to see which works better for treating opioid use disorder. If you are eligible, you will receive one of these forms for a year and regular check-ups.
