Recruiting studies
- 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.

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 - NCT05026138Recruiting
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.
Bethesda, MarylandAges 3–100 - NCT05036707RecruitingPhase 1/Phase 2
Study how tick bites change immune responses
This study looks at how a person’s immune system responds after exposure to Ixodes (black-legged) tick bites. It aims to better understand the body’s early immune reaction after tick exposure, using blood tests and small skin samples.
Bethesda, MarylandAges 18–99 - NCT05065216RecruitingPhase 2/Phase 3
Study drug for acute ischemic stroke started within 24 hours
This trial tests whether an investigational study drug can improve outcomes after an acute ischemic stroke (a stroke caused by blocked blood flow). You may be eligible if you are able to start treatment quickly after symptom onset and have a moderate stroke severity on a standard stroke exam.
Fairhope, AlabamaAges 18–90 - NCT05067179Recruiting
ALS patient data and tissue study
This study collects information from people diagnosed with ALS and, if applicable, studies ALS tissue samples. It aims to improve understanding of ALS using patient records and donated materials, which may help future treatments.
Chicago, IllinoisAges 18–90 - NCT05093335RecruitingEarly Phase 1
PET scan test for CXCR4 in many relapsed cancers
This early study tests a new PET scan tracer (a radioactive imaging agent) that may light up a cell marker called CXCR4 in certain blood and solid tumor cancers. It may help doctors see where cancers are and how much CXCR4 they have, which could guide future treatments.
New York, New YorkAges 18 years+ - NCT05103683RecruitingPhase 1
First-time test of TORL-1-23 for advanced solid tumors
This early study tests a new drug (TORL-1-23) in people with advanced solid cancers. It aims to find the safest dose and see how the tumor responds.
Fullerton, CaliforniaAges 18 years+ - NCT05104515RecruitingPhase 1
First cancer vaccine test for advanced lung, ovarian, or prostate cancer
This Phase 1 study tests OVM-200, a new cancer vaccine, to see how it is tolerated and how it affects the immune system in people with advanced NSCLC, ovarian cancer, or prostate cancer. You may be eligible if your cancer has already had approved treatment(s) and no further standard options are planned within the first two months.
London, LondonAges 18–75 - NCT05108818RecruitingPhase 4
Study immune responses after an flu shot in healthy adults
This study gives you a flu vaccine and measures how your immune system reacts, including both “blood immunity” and “cell immunity.” It’s for healthy adults and mainly aims to better understand how well flu vaccines work in people without major health issues.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05120596RecruitingPhase 1/Phase 2
Testing an immune-targeting drug by direct injection into tumors
This Phase 1/2 trial tests T3P, a new treatment given directly into reachable solid tumors, to see if it is safe and can help shrink tumors. It is for adults with advanced cancers when no curative treatment is available.
Pamplona, NavarreAges 18–74 - NCT05120635Recruiting
Study brain signals tied to fear and anxiety in RNS patients
This study records electrical brain activity to understand how fear and anxiety work in people who already have an RNS (responsive neurostimulation) device placed. It may help researchers develop better ways to monitor and treat anxiety-related symptoms in the future.
Los Angeles, CaliforniaAges 18–70 - NCT05157282Recruiting
Spinal cord stimulation to improve hand function after tetraplegia
This trial tests whether a special device that stimulates the spinal cord can help people with long-lasting neck spinal cord injuries recover useful hand movement and grip strength. It may help your nervous system communicate better so daily hand tasks become easier.
Chicago, IllinoisAges 18–70 - NCT05159466Recruiting
Transplant from HIV-positive donors to HIV-positive recipients
This trial studies whether it’s safe and effective for HIV-positive people to receive organ transplants from HIV-positive donors. It focuses on matching HIV treatment before and after transplant and checking for major complications.
Metairie, LouisianaAges 18 years+ - NCT05169541Recruiting
Testing a blood marker in repeated pregnancy loss
This study looks at whether a blood protein level called mannose binding lectin is linked to why some people have repeated pregnancy loss or unsuccessful embryo transfers. If you’ve had multiple losses or failed transfers, the study may help clarify biology behind reproduction and could guide future care.
AarhusAges 18–41 - NCT05196061Recruiting

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.
