This study tests a virtual reality program to help adults with autism cope with sensory problems and improve social skills. Participants will practice handling sensory situations in a safe VR environment.
TaipeiAges 20–45 - NCT05136846RecruitingPhase 1
Papaverine with chemoradiation for stage II–III lung cancer
This early-phase trial tests whether adding papaverine to standard chemoradiation can improve treatment for stage II–III non-small cell lung cancer (and some limited stage IV cases). It aims to see if the combination is safe and tolerable while targeting the cancer with radiation and chemotherapy.
Duarte, CaliforniaAges 18 years+ - NCT05011760RecruitingEarly Phase 1
PET brain scan with a cocaine-use disorder medicine test
This early-phase study uses a PET brain scan (a special imaging test) to see how the brain responds in people with cocaine use disorder. It aims to better understand brain activity and whether this scan approach could help research or future treatments.
Pittsburgh, PennsylvaniaAges 18–55 - NCT05051618Recruiting
Exercise program for depression in people with multiple sclerosis
This trial studies whether a structured exercise program can help reduce symptoms of major depressive disorder in people who also have multiple sclerosis. You’ll complete questionnaires, wear an activity sensor, and do exercise testing while being assigned to the study program.
Chicago, IllinoisAges 18–64 - NCT04984512RecruitingPhase 2/Phase 3
Testing mitizodone tablets for major depression symptoms
This trial studies whether mitizodone phosphate tablets can improve symptoms of major depressive disorder (MDD). It also checks the treatment’s safety, including mood and physical health effects.
Dongguan, GuangdongAges 18–65 - NCT04972136Recruiting
Brain stimulation treatment for depression in young adults with autism
This trial studies a noninvasive brain stimulation (rTMS) to help reduce depression symptoms in young adults who have autism. It aims to find out if this treatment can improve mood and daily functioning without requiring recent changes to medications.
Toronto, OntarioAges 16–35 - NCT04883515Recruiting
Glutamine drink for insulin resistance and bowel symptoms
This trial studies whether taking an oral glutamine supplement can improve insulin resistance and reduce bowel-related problems in people with obesity and irritable bowel syndrome. It may help your blood sugar regulation and digestive comfort if you meet the criteria.
RouenAges 18–65 - NCT04900623RecruitingPhase 2
Using HPV blood test to guide treatment for HPV throat cancer
This Phase 2 study tests a “risk-adapted” treatment plan for HPV-related throat cancer, using an HPV DNA blood test to help decide how treatment is done. If your baseline blood test shows detectable HPV DNA, the study may help tailor therapy to your risk and potentially improve outcomes while limiting unnecessary treatment.
Boston, MassachusettsAges 22 years+ - NCT04798274Recruiting
Brain wiring study in autism using safe hearing tasks
This study looks at how a brain chemical related to calming signals (“GABA”) may affect how people process sounds in autism. The goal is to understand brain function during hearing tasks, which could help guide future treatments.
Bethesda, MarylandAges 11–25 - NCT04806282Recruiting
Study to track hearing instability and find helpful targets
This study follows adults with hearing instability to better understand what causes it, measure it in new ways, and look for potential treatment targets. If you qualify, you may get hearing and balance-related testing (including scans) over a period of time.
Bethesda, MarylandAges 18–80 - NCT04751409RecruitingPhase 2
Less versus more follow-up after sarcoma surgery
This trial compares two schedules of post-treatment check-ups to see which one better supports patient quality of life. You’d fill out surveys for up to two years to measure how you feel over time.
Houston, TexasAges 18 years+ - NCT04703101RecruitingPhase 1

Study brain response to inflammation in depression
This early-stage study tests how your brain responds to an “inflammatory challenge” in people with major depressive disorder and in healthy volunteers. It may help researchers understand the immune-to-brain link in depression and guide future treatments.
Tulsa, OklahomaAges 18–65 - NCT04704505RecruitingPhase 2
Testosterone-like treatment plus radium for bone-spread prostate cancer
This trial studies whether adding a testosterone-related therapy (BAT) to radium-223 can better control prostate cancer that has spread mainly to the bones. It may help shrink tumors in the bone and slow PSA rises, which are a common marker of prostate cancer activity.
Baltimore, MarylandAges 18 years+ - NCT04663724Recruiting
Computer-based treatment for social anxiety disorder
This study is testing a computer-based treatment for social anxiety disorder. It may help reduce anxiety in social situations through a structured online program, and it also includes brain imaging (MRI) to see how the treatment affects the brain.

- Are there clinical trials for bipolar disorder i or ii?
- Yes. Clin2 currently lists 2,350 recruiting bipolar disorder i or ii 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 bipolar disorder i or ii 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 bipolar disorder i or ii 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.
