Study of severe HPV disease and why it keeps coming back
This study follows people with severe or hard-to-treat HPV-related conditions (and some closely related partners/household contacts) to learn how the virus causes illness and how the immune system responds. It may help doctors better predict who will develop severe disease and guide future treatments.

Interview study of caregiving networks over a person’s life
This study uses interviews and questionnaires to better understand who makes up a caregiver’s support network when caring for someone with a long-term health condition. Your answers may help researchers understand how caregiving changes over time and across different health situations.
Bethesda, MarylandAges 18–100 - NCT05047354Recruiting
Study cholesterol metabolism in rare genetic conditions
This study looks at body chemistry (cholesterol-related lab findings) and physical features in people with Smith-Lemli-Opitz syndrome and related rare genetic cholesterol disorders. It may help researchers better understand these conditions and how they affect the body.
Bethesda, MarylandAges 1 day–100 years - NCT05052216Recruiting
Wearable monitor study for kids’ sleep apnea
This study tests a wearable device that can help monitor breathing and sleep in children. It compares children with sleep apnea to children without sleep apnea using a simple nighttime monitoring approach.

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 - NCT04948658Recruiting
Freezing ovarian tissue to protect future fertility
This study looks at storing ovarian (ovary) tissue by freezing it for people at higher risk of losing fertility. It may help preserve options for having biological children later, especially for certain genetic conditions, cancer-related risks, or planned gonad removal.
Bethesda, MarylandAges 2–35 - NCT04930432RecruitingPhase 1/Phase 2
MCLA-129 for advanced EGFR- and MET-positive lung and other cancers
This early-phase trial tests MCLA-129, an antibody that targets EGFR and MET, in people with advanced cancers that have specific lab “biomarker” results. It’s for patients whose cancer has grown after standard treatments or can’t take standard treatment, with the goal of shrinking tumors and improving symptoms.
BaodingAges 18 years+ - NCT04958122RecruitingPhase 3
Antibiotic treatment trial for early syphilis
This Phase 3 study tests whether cefixime can treat primary, secondary, or early latent syphilis. It may help by offering another effective antibiotic option, including for some people who also have HIV (if well controlled).
Los Angeles, CaliforniaAges 18 years+ - NCT04943861Recruiting
Study on HIV and food insecurity support
This study is looking at food insecurity in adults living with HIV. It may help improve understanding of the barriers to healthy living and guide better support for people affected by HIV.
Winston-Salem, North CarolinaAges 18 years+ - NCT04888923Recruiting
How environmental exposures affect your health
This study observes how your body responds to environmental exposures or injuries over time. It aims to understand how different factors like genetics or lifestyle affect your health.
Research Triangle Park, North CarolinaAges 18–90 - NCT04874220Recruiting
Brain activity and real-world navigation
This study looks at how the brain helps us find our way around in real-world settings. Researchers will monitor brain activity using your RNS device while you navigate, which may help understand memory and spatial skills.
Los Angeles, CaliforniaAges 18–90 - NCT04821544Recruiting
Study of stress in new mothers and how it affects breastmilk
This study looks at how stress in new mothers may change their breastmilk and how that relates to newborn health outcomes. It is specifically recruiting mothers with babies in certain NICUs.
Coeur d'Alene, IdahoAges 18–50 - NCT04850456Recruiting
Gamma globulin treatment for critically ill children with inflammation surge
This trial studies whether giving “human gamma globulin” can improve outcomes in very sick children in the ICU who have a severe infection causing an extreme inflammation reaction (“inflammatory storm”). If you’re in the hospital ICU with this complication, the study may offer a targeted treatment strategy and careful monitoring.
Shanghai, Shanghai MunicipalityAges 4 weeks–18 years - NCT04848740Enrolling by invitation
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.
PristinaAges 20–60 - NCT04686682RecruitingPhase 1/Phase 2
Study drug for adults with advanced cancers or AML
This early study (Phase 1/2) tests a new medicine (JAB-8263) in adults with advanced solid tumors or recurrent/refractory AML. It aims to find a safe dose and see whether it can shrink tumors or control the cancer.
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT04708431Recruiting
Study of health and wellbeing in people with androgen insensitivity
This study looks at the long-term health and wellbeing of people with androgen insensitivity, a genetic condition that affects how the body responds to androgens (male-type hormones). It may help your care team understand what to watch for over time and improve future guidance for patients and families.
Bethesda, MarylandAges 8–99 - NCT04717349Recruiting
Study collects health information for kids’ and teens’ gynecology concerns
This is a research study that gathers information about pediatric and adolescent gynecology conditions. It may help researchers better understand these issues by learning about symptoms, care, and outcomes—without requiring a specific treatment.

Study how fat changes affect insulin resistance after bariatric surgery
This study looks at how your body’s fat under the skin and inside the abdomen may affect “insulin resistance,” a common problem linked with blood sugar control. It’s for people who are scheduled for bariatric (weight-loss) surgery, to learn more before and after surgery.

Using Leftover Surgery Tissue for Research
This study collects tiny pieces of tissue that would normally be thrown away during heart or bone surgery. Researchers will use these samples to better understand how tissues work and develop better treatments. Your participation involves letting doctors keep and study a small amount of tissue removed during your scheduled surgery.
AmiensAges 18 years+ - NCT04706481Recruiting
Use of stored, de-identified samples for research
This trial is for people who already agreed to let researchers use their stored biological samples and medical information that has been removed of personal identifiers. It may help future studies by allowing researchers to analyze existing samples without using new samples from you.

Common questions
- Are there clinical trials for humans?
- Yes. Clin2 currently lists 1,228 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.
