Personalized immune cell therapy for advanced solid tumors
This Phase 1 study tests engineered immune cells (TILs/CAR-TILs) made from your tumor to treat advanced solid cancers that have not responded to standard treatments. It may help your immune system better recognize and attack the cancer, but it is mainly focused on safety and early results.
GuangzhouAges 18–85 - NCT03778814RecruitingPhase 1
Personalized T-cell therapy for advanced lung or solid tumors
This Phase 1 study tests a lab-made immune cell treatment made from your own blood cells (T cells) to fight advanced lung cancer or other solid tumors. You may be eligible if your tumor can be biopsied and the lab can successfully prepare T cells that strongly recognize and attack your cancer.
Guanzhou, GuangdongAges 18–75 - NCT04803318RecruitingPhase 2
Test of three targeted medicines for advanced solid tumors
This Phase 2 study tests trametinib plus everolimus plus lenvatinib in people with advanced solid tumors that have come back or cannot be treated anymore. It aims to control tumor growth and symptoms when standard options have not worked.
Guangzhou, GuangdongAges 18–85 - NCT05779917RecruitingPhase 1
CAR-T cells for cancers that have specific target proteins
This Phase 1 trial tests a customized immune therapy (CAR-T cells) for advanced cancers that have the proteins mesothelin, GPC3, and/or GUCY2C. It may help your body better recognize and kill cancer cells, but early-phase trials mainly focus on safety and learning how well the treatment works.
Guangzhou, GuangdongAges 18–75 - NCT06195384RecruitingPhase 1
Personalized mRNA vaccine for advanced solid tumors
This trial tests a personalized mRNA vaccine made from your tumor's unique markers (neoantigens) to train your immune system to fight cancer. It is for people with advanced solid tumors who have not had gene therapy and are healthy enough for the vaccine.

Study of AML genes and drug response in young patients
This trial looks at how childhood, teen, and young adult acute myeloid leukemia (AML) changes at the genetic level and how cells respond to multiple drugs. It may help doctors understand which treatments work best and how leukemia interacts with supportive cells in the bone marrow.
AmiensAges Up to 25 years - NCT06195293RecruitingPhase 1

- How do I know if I qualify for a adult 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 adult 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.
