Recruiting studies
- NCT03153527RecruitingPhase 4
Testing slow steroid taper versus stopping suddenly
This trial studies whether it’s safer or works better to slowly reduce steroids versus stopping them abruptly after long-term use. It may help people who are currently on daily steroid tablets and don’t medically need a taper just to treat their underlying condition.
FrankfurtAges 18 years+ - NCT03059173RecruitingPhase 3
Myo-inositol to help women with PCOS get pregnant
This trial tests whether taking myo-inositol helps women with PCOS improve fertility and get pregnant. It compares outcomes in women who have not used the common fertility medicine clomiphene citrate (CC) recently.
LilleAges 18–35 - NCT03083431RecruitingPhase 2
Oral propranolol to prevent early retinopathy in preemies
This trial tests whether giving propranolol by mouth to certain very premature babies with early eye changes can stop retinopathy of prematurity from getting worse. It may help reduce the need for eye treatments later on.
Tübingen, Baden-WurttembergAges 1 month–3 months - NCT02922894RecruitingPhase 4
Testing sleep apnea care in people with spinal cord injury
This study looks at treatment for sleep apnea (breathing pauses during sleep) in adults with a spinal cord injury. If you qualify, the trial team may help manage sleep-related breathing problems and track how well the treatment works.
Detroit, MichiganAges 18–89 - NCT03016819RecruitingPhase 3
Test drugs anlotinib and catequentinib for advanced sarcoma
This Phase 3 study tests two anti-cancer medicines (anlotinib and catequentinib) for people with certain advanced soft-tissue sarcomas, including alveolar soft part sarcoma, synovial sarcoma, and leiomyosarcoma. It is designed for tumors that cannot be removed and that have either grown despite treatment or no longer respond to standard options.
Phoenix, ArizonaAges 18 years+ - NCT02991625Enrolling by invitation
Brain scan study to find markers for chronic back pain
This study uses brain imaging (MRI scans) to look for “biomarkers” (measurable signs) that may relate to chronic low back pain. It compares people with long-lasting back pain to healthy volunteers to understand what brain patterns are linked to pain.
Halifax, Nova ScotiaAges 18–75 - NCT02994433RecruitingPhase 1
Testing nitrous oxide for depression brain circuit activity
This early study tests whether nitrous oxide, aimed at specific brain circuits, can change depression-related brain activity. It is mainly for adults with major depression or treatment-resistant depression, and includes brain imaging during the study.
St Louis, MissouriAges 18–65 - NCT02446262Recruiting
Study of how the brain and mind shape pain in healthy adults
This study tests how people sense heat and pain, and how the brain and emotions may influence that experience. It is designed for healthy adults and may involve training sessions and (for some parts) MRI scanning.
Bethesda, MarylandAges 18–50 - NCT02521311RecruitingPhase 2
Clemastine to help restore nerve covering in optic neuritis
This Phase 2 trial tests whether clemastine can help regrow the protective covering around the optic nerve after acute optic neuritis (an inflammation-related vision problem). It may help improve vision recovery and signal how well “remyelination” happens.
San Francisco, CaliforniaAges 18–55 - NCT02314988RecruitingPhase 2/Phase 3
Tranexamic acid to reduce bleeding in spine surgery
This trial tests whether tranexamic acid (a medicine that helps blood clot) can reduce blood loss during long spine surgery after an injury. It may help lower the chance of needing transfusions and manage surgical bleeding.
San Francisco, CaliforniaAges 18–80 - NCT02455479RecruitingPhase 1
Safety study of a vaccine for cocaine dependence
This early-stage study tests how safe an experimental “cocaine vaccine” is and how the body reacts to it. You must also be in behavioral therapy, and the study aims to see whether the vaccine can be given safely to people with cocaine use disorder.
New York, New YorkAges 21–69 - NCT02497261Enrolling by invitation
Study factors that predict peanut allergy at age five
This study looks at which early test results and symptoms help predict whether a child will still have a peanut allergy by age 5. It may help families and doctors better understand who is at higher risk and plan next steps.
Ages 4–10 - NCT02172651RecruitingEarly Phase 1
Vitamin D during early colon cancer or liver surgery
This trial studies whether taking higher-dose vitamin D3 around the time of colon cancer (or colon cancer with resectable liver metastases) surgery improves outcomes. It focuses on safety and possible effects on cancer-related health after surgery.
Boston, MassachusettsAges 18 years+ - NCT02411773RecruitingPhase 1
Test a nerve-blocking medicine in kidney disease
This Phase 1 study tests whether a medicine that reduces nerve signals (“sympatholysis”) is safe and how it affects people with chronic kidney disease. It may help researchers understand new ways to protect the kidneys, but the main goal here is safety.
Decatur, GeorgiaAges 18–75 - NCT02357654RecruitingPhase 4
Hormone treatment to support the uterine lining in IVF cycles
This trial tests whether a hormone called GnRH can help support the lining of the uterus after IVF, ICSI, or frozen embryo (FET) embryo transfer. It may be offered around the time of embryo transfer to improve the chances of a successful implantation.
Hasbrouck Heights, New JerseyAges 18–40 - NCT02064673RecruitingPhase 3
Adjuvant curcumin after prostate surgery to prevent cancer return
This Phase 3 trial studies whether taking curcumin (a supplement made from turmeric) after radical prostatectomy can help keep prostate cancer from coming back. Participants are men with low-risk, surgery-only disease and undetectable PSA, and the study checks recurrence-free survival over time.
Dallas, TexasAges 30–80 - NCT01370512Enrolling by invitationPhase 2
Droxidopa plus pyridostigmine for low blood pressure on standing
This Phase 2 study tests whether the medicines droxidopa and pyridostigmine can improve symptoms of orthostatic hypotension, which is low blood pressure when you stand up. It is designed for people whose low blood pressure is caused by problems with the nerves that control blood pressure.
Rochester, MinnesotaAges 18 years+ - NCT00409435RecruitingPhase 2
Pyridostigmine trial for postural tachycardia syndrome symptoms
This trial tests whether pyridostigmine helps people with postural tachycardia syndrome (POTS), which causes heart rate to rise when you stand up and can lead to unpleasant symptoms. You would be screened based on your tilt-table heart-rate response and your standing-related symptoms.
Rochester, MinnesotaAges 15–55

Common questions
- Are there clinical trials for placebo?
- Yes. Clin2 currently lists 5,154 recruiting placebo 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 placebo 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 placebo 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.
