Recruiting studies
- NCT06764719Recruiting
Hair follicles for cell therapy
This trial tests if special hair follicles can be used for cell replacement therapy in disease. It may help people with certain medical conditions.
Toronto, QuebecAges 18–80 - NCT06710769Recruiting
Ovarian tissue freezing before cancer treatment
This study helps people who are about to start cancer treatment (or have certain health conditions) preserve their ability to have children later. It removes and freezes a small piece of ovarian tissue before treatments that could damage the ovaries.
Phoenix, ArizonaAges 1–25 - NCT05458440Recruiting
Study using immune cells from recovered COVID-19 donors
This study collects immune cells from people who recovered from COVID-19 and may use them to boost protection against SARS-CoV-2. It’s for hospitalized patients who already show a certain level of COVID-19 fighting immune response.
Vandœuvre-lès-Nancy, LorraineAges 18–70 - NCT06692049Recruiting
Freezing gonadal tissue to preserve fertility in children with a disorder of sex development
This study tests a procedure that freezes and stores gonadal tissue (tissue that makes eggs or sperm) to help preserve the chance of having biological children in the future. It is for children and young adults under 30 who have a disorder of sex development and either have a risk of cancer in that tissue or will have it removed for another medical reason.
Chicago, IllinoisAges Up to 30 years - NCT06042140Recruiting
Umbilical cord patch for spina bifida repair before birth
This study tests whether a patch made from donated umbilical cord can help repair spina bifida in the womb using a minimally invasive fetoscopic approach. If successful, it may reduce the need for more invasive open fetal surgery.
Houston, TexasAges 18 years+ - NCT06253507Enrolling by invitationPhase 1/Phase 2
Gene Therapy for Chronic Granulomatous Disease
This study tests a new gene therapy for people with a rare immune disorder called chronic granulomatous disease (CGD), which causes repeated infections. The treatment uses a modified virus to deliver a healthy gene to your blood stem cells, potentially helping your immune system fight off bacteria and fungi. The goal is to reduce the risk of severe infections and improve overall health.
Bethesda, MarylandAges 3–65 - NCT06216756Recruiting
Frozen cartilage transplant for knee cartilage defects
This trial tests a frozen cartilage transplant (called an osteochondral allograft) for people with painful knee cartilage defects. It aims to see if this procedure can help relieve pain and improve knee function.
Phoenix, ArizonaAges 12–60 - NCT06063551Recruiting
Freezing testicular tissue to protect fertility in boys with cancer
This study freezes a small piece of testicular tissue from boys with cancer before they start treatment that could cause permanent infertility. The tissue is stored so that, in the future, it might help them have biological children.
Edinburgh, LothianAges 1 day–18 years - NCT05875155Recruiting
Saving eggs by freezing ovarian tissue during cancer or surgery care
This trial looks at freezing ovarian tissue to help protect future fertility for people who may lose ovarian function from medical treatments or ovarian surgery. It may help you preserve the chance to have children later when egg or embryo freezing alone isn’t an option.
Pittsburgh, PennsylvaniaAges Up to 39 years - NCT05830929Recruiting
Freezing ovarian tissue and later putting it back
This study tests a way to protect future fertility in young people who need cancer treatment. It freezes ovarian tissue before treatment and, if appropriate, later returns it to the body to help restore hormone production and possible future pregnancy.
Hong KongAges 1 month–35 years - NCT01558544Recruiting
Freezing ovarian tissue for future fertility after early menopause risk
This study looks at freezing (cryopreserving) ovarian tissue in people who are at risk of early menopause because of cancer treatment or surgery. It may help preserve natural hormone function and possible future fertility for those who cannot or do not want to freeze eggs or embryos.
New York, New YorkAges Up to 45 years - NCT05309746Recruiting
Save ovarian tissue before cancer treatment
This trial studies freezing (cryopreserving) ovarian tissue before treatment that may permanently affect fertility and hormone production. You might consider it if you are planning surgery, chemotherapy, or radiation soon and want to preserve future options.
Chicago, IllinoisAges Up to 30 years - NCT05299710Recruiting
Store ovarian tissue for future fertility in children
This study looks at freezing (cryopreserving) ovarian tissue before certain cancer treatments or surgeries that may affect fertility. It may help preserve the ability to have children later, especially when future fertility is at risk.
Chicago, IllinoisAges Up to 11 years - NCT04619524Recruiting
Blood and lining tests during IVF cycles to guide endometrial timing
This study looks at “biomarkers” (test signals in your blood or cycle data) to better judge how ready the womb lining is during IVF. It compares two types of IVF hormone setups to see which approach best matches endometrial receptivity and supports successful embryo transfer.
Brno, South MoravianAges Up to 36 years - NCT04186520RecruitingPhase 1/Phase 2
CAR T-cell treatment for hard-to-treat B-cell lymphomas
This trial studies a type of lab-made immune cell therapy (CAR T) using cells called CAR-20/19-T. It is for adults with relapsed or refractory B-cell cancers, aiming to reduce or eliminate lymphoma in people whose disease has come back or not responded to standard treatments.
Milwaukee, WisconsinAges 18–80 - NCT03180918Recruiting
Freezing testicular tissue before very fertility-damaging cancer treatment
This trial studies whether freezing a small piece of testicular tissue before certain aggressive cancer treatments can help preserve future fertility. It is meant for children or teens who face a high risk of infertility from specific treatments when usual sperm freezing is not possible.
BaselAges 3 months–18 years - NCT02972801Recruiting
Freezing testicle tissue to protect future fertility
This study helps collect and freeze testicle tissue for people who must have surgery, chemotherapy, medicines, or radiation that could permanently harm fertility. You may join if you’re newly diagnosed or need planned treatment that threatens testicular function, and you agree to long-term follow-up.
Pittsburgh, PennsylvaniaAges Any age - NCT01870752Recruiting
Transplanting frozen ovarian tissue to help you try for pregnancy
This trial studies whether thawed, previously frozen ovarian tissue can be transplanted to help people with ovarian insufficiency become pregnant. It may help if you already have cryopreserved ovarian tissue stored and your care team feels you’re a good candidate for the procedure.
Philadelphia, PennsylvaniaAges 18–45

Common questions
- Are there clinical trials for cryopreservation?
- Yes. Clin2 currently lists 42 recruiting cryopreservation 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 cryopreservation 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 cryopreservation 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.
