First study drug BB-1705 for advanced solid tumors
This Phase 1 trial tests BB-1705 in people with advanced or metastatic (spread) solid tumors that cannot be removed with surgery. It mainly focuses on safety and how the drug behaves in the body, and may offer an option for patients when standard treatments have not worked.
BeijingAges 18–78 - NCT05046080Recruiting
Testing after diagnosis of clear cell cervical cancer
This study is for people who have been diagnosed with clear cell cancer of the cervix. It looks at cancer tissue and related lab tests to better understand the disease and possibly guide care decisions.
Houston, TexasAges Any age - NCT04611022Recruiting
Help increase HPV vaccine completion in Denver families
This study tests an educational program to help people in Denver who have not yet started the HPV vaccine (or haven’t finished it) complete the vaccine series. It may help families understand the vaccine and follow through with completing the recommended doses.

Study follow-up for high-risk HPV in people with gynecologic history
This study looks at follow-up care for anal (rear passage) HPV risk in adults who previously had high-risk HPV–related gynecologic changes. It aims to better track disease that may be related to HPV and possibly help guide future monitoring.
ParisAges 18 years+ - NCT04836156RecruitingPhase 1/Phase 2
Personalized pre-surgery treatment for HER2-negative early breast cancer
This study tests a treatment plan chosen using lab drug testing on a patient’s tumor (in a dish). It may help improve outcomes for people with early breast cancer that is HER2-negative by matching therapy to what the tumor seems sensitive to.
BeijingAges 18–75 - NCT04874220Recruiting
Brain study of real-world navigation in people with RNS
This study looks at how the brain works while people navigate in everyday life. It includes people who already have an RNS device placed in their brain and helps researchers understand the brain activity tied to spatial navigation.
Los Angeles, CaliforniaAges 12–70 - NCT05477849RecruitingPhase 1
Study drug for people with advanced solid tumors
This Phase 1 trial tests the safety and early effects of VG2025 in people with advanced solid cancers that have stopped responding to standard treatments. It’s mainly looking for side effects and how the body processes the drug, and it may offer a new option when other treatments haven’t worked.
Hangzhou, ZhejiangAges 18–75 - NCT07104240Recruiting
Improving HPV vaccination for preteens ages 9-12
This study tests a program designed to help primary care practices increase HPV vaccination rates among adolescents aged 9 to 12 who haven't yet been vaccinated. It aims to find out if providing practices with resources and support can lead to more kids getting the HPV vaccine.
Atlanta, GeorgiaAges 9 years+ - NCT05440617Recruiting
Biobank for people having testicle-protecting cancer treatment
This study collects and stores biological samples from people who are planning to undergo OTC, a treatment used to help protect fertility during cancer therapy that can harm reproductive cells. It may help future research by providing researchers with tissue/blood samples linked to this treatment.
Bethesda, MarylandAges 4–35 - NCT05442463Recruiting
Hormone effects on blood vessel narrowing in kidneys and arteries
This study looks at how hormone treatments (estrogen, progesterone, or testosterone) may affect how blood vessels tighten in the body, including in the kidneys. Researchers measure these effects to understand potential impacts on blood flow and blood vessel control.
Calgary, AlbertaAges 18–90 - NCT03849963Recruiting
Brain imaging study of energy use and brain chemicals
This study uses MRI scans to measure how your brain uses energy and how certain brain chemicals are made. It’s for healthy adults and can help researchers understand normal brain chemistry and metabolism.
Dallas, TexasAges 18–60 - NCT04234724Recruiting
Study of how ANGPTL3 gene variants affect body functions
This study looks at how different ANGPTL3 gene versions may change normal body measurements (such as blood and metabolism). It may help researchers understand why these genetic differences affect health, especially related to fats (lipids) in the body.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04232917RecruitingPhase 4
Testing a treatment to help clear genital high-risk HPV
This trial studies 2LPAPI® to see if it helps the body clear high-risk HPV infections in the cervix. It may be an option if you have a current HPV infection with mild/early abnormal cervical findings and can complete follow-up for about a year.
BrusselsAges 25–45 - NCT04049604Recruiting
Study of pregnancy cancer risk after unusual DNA screening
This study follows pregnant people who had unusual noninvasive prenatal blood test results, to better understand the natural course and possible causes, including concerns about maternal cancer. You may join during pregnancy or up to 2 years after delivery, and you would share medical information and undergo follow-up visits.
Bethesda, MarylandAges 18–100 - NCT04101188Recruiting
Study how extra potassium affects blood vessels
This study looks at how eating more potassium may protect blood vessels in healthy people. You may be eligible if you have normal blood pressure and a normal heart rhythm test, and you do not have certain health conditions.
Newark, DelawareAges 18–45 - NCT04066127Enrolling by invitation
Heart transplant study comparing two types of heart storage
This trial tests whether using a different method to store a donated heart before transplant improves outcomes. It compares “non-ischemic preservation” versus standard cold storage for people getting a new heart.
Lund, Skåne CountyAges 18 years+ - NCT03253705Recruiting
Donate small blood samples to study heart and inflammation health
This study collects small blood samples (and sometimes samples during treatment) to help researchers understand diseases involving the heart, inflammation, and blood vessel function. It may help improve future tests and treatments by giving scientists usable human data.

Tested implant for worsening thin corneas
This trial looks at whether placing a donor-like cornea “lenticule” implant can help people whose cornea is getting worse, becoming thin, and causing blurry or reduced vision. The goal is to see if the implant can improve corneal clarity and vision in progressive disease.

Share whole-genome or exome data for research
This trial is about building a large library of genetic test results (whole exome or whole genome sequencing) that researchers can use. You may be eligible if your sequencing data is available and you (or your study contact) can be reached again so researchers can include your information responsibly.

Common questions
- Are there clinical trials for humans?
- Yes. Clin2 currently lists 1,248 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.
