This early study tested a laser treatment for people with excessive sweating (hyperhidrosis). The approach used a dye to mark sweat glands, then a special laser to destroy them. Only 2 people were enrolled, and the study was terminated early, so we have very little data on whethe…

This study tested the anti-inflammatory drug naproxen sodium for treating obsessive-compulsive symptoms in children aged 6-15 with PANDAS, a condition linked to strep infections. The trial was double-blind and placebo-controlled, but it was terminated early after enrolling only 2…

This study tested a combination of two drugs—tivozanib and enzalutamide—in men with advanced prostate cancer that had stopped responding to standard hormone therapy. Enzalutamide blocks male hormones that fuel cancer growth, while tivozanib cuts off the tumor's blood supply. The …

This study tested whether breathing in nitric oxide gas could keep mild-to-moderate COVID-19 from becoming severe. Researchers enrolled 62 hospitalized adults who were breathing on their own. The goal was to see if the gas reduced the need for a breathing tube. The trial was stop…

This phase 2 study tested umbralisib (a PI3K blocker) plus rituximab (an antibody that targets B-cells) as the first treatment for people with follicular or marginal zone lymphoma. The goal was to see how many patients had their tumors disappear completely. Only 18 people enrolle…

This study tested a drug called MBG453 in 10 people with a type of bone marrow disorder called lower-risk myelodysplastic syndromes (MDS). The goal was to see if the drug could improve blood cell counts and reduce the need for transfusions. The trial was terminated early, so the …

This pilot study looked at whether radiation therapy could help people with lymphoma that did not respond to CAR T cell therapy. Only 3 participants were enrolled before the study was terminated. The main goal was to check safety and side effects of adding radiation shortly after…

This study tested whether breathing in nitric oxide gas could prevent healthcare workers from catching COVID-19. The plan was to enroll 470 workers, but the trial was stopped early with only 24 participants. Workers in the treatment group inhaled the gas at the start and end of e…

This study looked at whether adding guanfacine (a blood pressure medicine) to morphine could reduce pain sensitivity and tolerance in people with chronic neck or back pain. The study planned to enroll 137 adults who had not taken opioids recently. However, the study was terminate…

This study looked at whether adding guanfacine to opioid painkillers could reverse the extra pain sensitivity that long-term opioid use can cause. It involved 8 adults with chronic neck or back pain who were already taking opioids. The study was terminated early, so results are l…

This study tested a short course of targeted radiation (IMRT) given over one week before surgery for rectal cancer. The goal was to see if this approach could reduce side effects like bowel problems and improve quality of life compared to standard longer treatments. Only 2 people…

This study tested whether a fractional carbon dioxide laser can improve moderate to severe acne in adults aged 18 to 40. Participants received up to 3 laser treatments and were followed for changes in blemish count and skin severity. The trial was terminated early and only enroll…

This study tested a new cooling device to manage pain during radio-frequency microneedling, a cosmetic skin treatment. It involved 6 healthy women and measured pain levels after different cooling times. The study was terminated early, so results are limited.

This study tested whether a special laser could improve scars and skin hardening from scleroderma. Only 6 people took part, and the study was stopped early. Researchers measured scar changes using a standard scale, but the small size and early termination mean we cannot draw firm…

This study tested whether memantine, a medication for Alzheimer's, could improve social skills in youth aged 8-18 with autism or nonverbal learning disability. The trial was stopped early after enrolling only 25 participants. The main goal was to measure changes in social functio…

This study tested whether pramipexole (Mirapex), a drug for restless legs syndrome, could also reduce symptoms of opioid withdrawal in people with opioid use disorder. The trial planned to enroll 75 adults but was terminated early. Researchers measured changes in restless legs se…

This study looked at how a gentle brain stimulation technique called tDCS affects thinking and behavior in children aged 10-17 with obsessive-compulsive disorder (OCD). The goal was to understand brain processes linked to OCD, not to treat the condition. Only 6 participants were …

This study looked at how healthy adults respond to breathing air with less oxygen for up to 7 days. Researchers measured oxygen levels in the blood, red blood cell production, and lung pressure to understand the body's adjustments. The goal was to define safety and basic response…

This study aimed to help astronauts on long spaceflights stay focused and perform well despite stress, lack of sleep, and isolation. Researchers planned to use biosensors to adjust the work environment in real time for each crew member. The study involved 80 healthy adults and me…

This study explored whether a non-invasive technique called transcranial magnetic stimulation (TMS) could improve memory in healthy older adults and those with mild memory problems due to Alzheimer's. Researchers used TMS to stimulate brain networks linked to memory and measured …

This study looked at a type of spinal cord stimulation (SCS) that doesn't cause tingling, called paresthesia-free SCS, in 10 adults with chronic pain. Researchers wanted to see how well it works and how it affects pain perception. The study was terminated early, so the findings a…

This study aimed to compare two ways of setting breathing machine pressure (PEEP) in patients with severe lung injury (ARDS). The goal was to see which method better protects the lungs and heart. Only 2 patients were enrolled before the study was stopped, so no meaningful results…

This study tested a special band called AirGo to monitor breathing patterns in hospitalized COVID-19 patients with respiratory failure. The goal was to see if the band could detect early signs of worsening breathing, helping doctors decide when to use a breathing tube. The study …
