CP-506 for hard-to-treat cancers with DNA repair defects
This Phase 1/2 study tests CP-506 in people with advanced solid tumors that have specific DNA repair problems (homologous recombination or Fanconi anemia-related defects). It may be used alone or combined with carboplatin or an immune therapy, aiming to shrink tumors or improve control when standard options are limited.
BrusselsAges 18 years+ - NCT06154252RecruitingPhase 2/Phase 3
Study of CABA-201 for active myositis in adults and children
This trial tests a new treatment called CABA-201, which uses your own immune cells modified to attack the overactive cells causing myositis. It is for people with active disease that hasn't improved enough with standard therapies.
Orange, CaliforniaAges 6–75 - NCT06132698RecruitingPhase 2
Immunotherapy injected into spinal fluid for lung cancer that has spread to the brain lining
This trial tests giving an immunotherapy drug directly into the spinal fluid for people with non-small cell lung cancer that has spread to the lining of the brain or spinal cord. The goal is to see if this approach can help control the cancer while allowing you to continue other treatments you may already be taking.
Chengdu, SichuanAges 18–75 - NCT06148025RecruitingPhase 4
Antibiotics and vaccine response study
This study looks at whether taking a short course of antibiotics changes how well vaccines work. You would receive the BCG vaccine (for tuberculosis) and possibly the yellow fever vaccine, and we would check your immune response over several months.
Adelaide, South AustraliaAges 18–35 - NCT06133530Enrolling by invitation
Human milk sugars for gut health in Antarctica
This study tests whether natural sugars found in human milk (called HMOs) can improve gut health and the immune system. Researchers are looking for healthy adults who are willing to travel to Antarctica for the study.
ErfurtAges 18–65 - NCT03016806Recruiting
Umbilical cord blood transplant from unrelated donors
This trial studies transplanting healthy blood-forming cells from an umbilical cord blood donor who is not related to you. It may help people with certain blood cancers, immune disorders, or other serious diseases when a standard transplant plan is needed.
Rochester, New YorkAges 2 months–75 years - NCT06116032Recruiting
Immune profiling for cancer immunotherapy response
This trial studies immune system changes in cancer patients receiving immunotherapy, such as checkpoint inhibitors or cell therapies. It aims to understand why some people respond better than others.
Lebanon, New HampshireAges 18 years+ - NCT01720836RecruitingPhase 1/Phase 2
MUC1 peptide vaccine study for non-small cell lung cancer
This trial tests a vaccine made from a lung-cancer target (MUC1) to help your immune system recognize and fight the cancer. It is designed to measure immune response and safety, and it may help some people develop a stronger anti-cancer immune reaction.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT06032923RecruitingPhase 1/Phase 2
Does vitamin B3 boost help lupus symptoms?
This study tests whether a form of vitamin B3, called nicotinamide riboside, can improve immune function and reduce inflammation in women with mild to moderate lupus. It may help understand if boosting NAD+ levels offers a new way to manage the disease.

Common questions
- Are there clinical trials for immunization?
- Yes. Clin2 currently lists 975 recruiting immunization 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 immunization 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 immunization 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.
