Canakinumab shot for lower-risk MDS and related blood disorders
This trial tests canakinumab, a medication that blocks inflammation, given as a skin (subcutaneous) injection. It is for adults with lower-risk myelodysplastic syndromes (MDS) or a related condition (chronic myelomonocytic leukemia or CCUS) to see if it can improve blood counts and reduce problems like anemia or transfusion needs.

Scan trial to track a new tracer in suspected bacterial infections
This Phase 1 study uses a special scan tracer ([18F]F-TMP) to see how it moves in the body and how fast it changes in people with suspected or known bacterial infections. It’s mainly testing the scan’s behavior and safety, which may help future infection-targeting imaging.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04335383Recruiting
Study blood antibodies for a Pseudomonas-targeting treatment
This study looks at people’s blood to see if they already have antibodies that recognize Pseudomonas aeruginosa, a type of bacteria. If you qualify for the prospective part, they may collect blood samples at Grenoble University Hospital and use your results to support future treatment testing.

Cord cell treatment for severe systemic sclerosis symptoms
This early-phase study tests whether umbilical cord-derived “cord blood–type” cells can reduce or improve severe systemic sclerosis (a type of hardening/scarring disease of connective tissue). It may help people whose current standard treatments haven’t worked or caused side effects.
Montreal, QuebecAges 18 years+ - NCT04363541Recruiting
Thermotherapy for mild to moderate COVID-19 symptoms

Guadalajara, JaliscoAges 18 years+ - NCT04396899RecruitingPhase 1/Phase 2
Stem cell heart patch for advanced heart failure
This early-phase study tests a lab-made heart tissue (“engineered myocardium”) placed surgically to help the heart work better in people with advanced heart failure. It mainly checks safety first, and also looks for signs the patch can improve heart function in selected patients.
Göttingen, Lower SaxonyAges 18–80 - NCT04413994Recruiting
Exclusive breast milk study in preterm babies
This study tests whether feeding extremely preterm babies only human milk (no formula) affects early health outcomes, including risks that may develop later. It also includes term-born babies for comparison. The study is mainly about feeding and safety, and you would follow the study’s feeding plan.
Innsbruck, TyrolAges 1 day–5 years - NCT04422366RecruitingPhase 3
9-valent HPV vaccine study for healthy Chinese women
This trial tests a 9-type HPV vaccine to see how well it works, how it helps the body build protection, and whether it’s safe. It’s for healthy Chinese women who have not had HPV vaccination before and meet specific health and timing requirements.
Liuzhou, GuangxiAges 20–45 - NCT04430257Recruiting
PrEP for people at higher risk of HIV
This study checks whether taking HIV prevention medicine called PrEP can help protect people who are not living with HIV but have recent risk of HIV exposure. You may qualify if you have ongoing risk and are not already taking PrEP.
Cambridge, MassachusettsAges 18 years+ - NCT04445285RecruitingPhase 2
Test drops to thin lung mucus in severe COVID-19
This Phase 2 trial tests rhDNase (a medication similar to Pulmozyme) to improve outcomes and reduce the risk of death in people with severe COVID-19 causing breathing failure. It’s meant for adults who need high-flow oxygen or a breathing machine.
Mobile, AlabamaAges 18 years+ - NCT04520178RecruitingPhase 2/Phase 3
5HTP trial for long-term spinal cord injury
This trial tests whether 5HTP can help people with spinal cord injury caused by trauma at least 6 months ago. It is mainly designed to see if the treatment is safe and helpful over the study period.
Louisville, KentuckyAges 18–65 - NCT04525833Recruiting
Visit Tzu Chi gastroenterology clinic study
This study looks at people who have visited a Tzu Chi Hospital gastroenterology clinic. It may help researchers understand liver and other whole-body health conditions in patients who receive care there.

PET scan study using a cholesterol-tracking tracer in healthy adults
This early study tests how well a special PET scan tracer can show cholesterol movement in the body. It is for healthy adults who do not have known adrenal problems, and it aims to collect basic imaging safety and dose information.

This trial studies whether adding BNT113 to pembrolizumab works better and is safe for people with HPV16-positive head and neck cancer that can’t be cured with local treatments. It also compares outcomes to pembrolizumab alone, specifically for tumors that show PD-L1 in testing.
Los Angeles, CaliforniaAges 18 years+ - NCT04537403RecruitingPhase 1
PET scan study of artery inflammation marker in plaque
This Phase 1 study tests whether a special PET scan can detect a specific inflammation signal (CCR2) in atherosclerosis—fatty plaque buildup in blood vessels. It may help future doctors better see which plaques are more inflamed and potentially more dangerous.

Common questions
- Are there clinical trials for humans?
- Yes. Clin2 currently lists 1,243 recruiting humans 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 humans 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 humans 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.
