New Cancer Drug for Children With Hard-to-Treat Solid Tumors
This trial tests a new drug called ifinatamab deruxtecan in children whose solid tumors (cancers that form lumps, excluding brain tumors) have come back or stopped responding to previous treatments. The drug is designed to target and kill cancer cells while potentially causing fewer side effects than standard chemotherapy.
Los Angeles, CaliforniaAges 1 month–17 years - NCT06941272RecruitingPhase 1/Phase 2
Study of patritumab deruxtecan for children with hard-to-treat solid tumors
This trial tests a new drug, patritumab deruxtecan, in children and adolescents whose rhabdomyosarcoma or hepatoblastoma has returned or not responded to at least one prior treatment. The goal is to see if the drug can shrink tumors or stop them from growing.
Los Angeles, CaliforniaAges 1 month–17 years - NCT05285358RecruitingPhase 1
Aerosol chemo plus standard drugs for bile duct and gallbladder cancer
This trial tests a new way to give the drug paclitaxel directly into your belly as a mist, along with two standard chemo drugs given through your veins, for bile duct or gallbladder cancer that has spread to the lining of the belly. The goal is to see if this approach can better control the cancer in the belly.
Duarte, CaliforniaAges 18 years+ - NCT06395103RecruitingPhase 1/Phase 2
Zilovertamab vedotin for blood cancers and solid tumors
This trial tests a new drug called zilovertamab vedotin for children and young adults with certain blood cancers or solid tumors. The drug is designed to target and kill cancer cells, and the study will see if it is safe and effective.
Los Angeles, CaliforniaAges 6 months–25 years - NCT04192344RecruitingPhase 1
First test of an anti-cancer drug for advanced solid tumors
This Phase 1 study tests how safe a new drug (ABSK-021) is, what side effects it causes, and how the body processes it in people with advanced solid tumors. You may be eligible if your cancer has grown despite standard treatments or if no standard treatment exists.
Beverly Hills, CaliforniaAges 18 years+ - NCT06131840RecruitingPhase 1
Study of SGN-CEACAM5C for advanced solid tumors
This trial tests a new drug called SGN-CEACAM5C in people with advanced solid tumors that have not responded to other treatments. The drug targets a protein on cancer cells to try to stop them from growing.
Duarte, CaliforniaAges 18 years+ - NCT06051695RecruitingPhase 1/Phase 2
CAR T cell therapy for mesothelin-positive solid tumors
This trial tests a new type of immune cell therapy (CAR T-cells) designed to target cancer cells that have a protein called mesothelin but have lost a marker that lets them hide from the immune system. It's for people with advanced solid tumors who have already tried standard treatments.
Los Angeles, CaliforniaAges 18 years+ - NCT07719361RecruitingPhase 1
New drug for advanced, treatment-resistant prostate cancer
This study tests an experimental drug for men whose prostate cancer has spread and stopped responding to standard hormone therapies. It may be an option if your PSA is rising despite treatment with drugs like enzalutamide or abiraterone.
Los Angeles, CaliforniaAges 18 years+ - NCT03866382RecruitingPhase 2
Immunotherapy plus a targeted drug for rare genitourinary tumors
This Phase 2 study tests whether nivolumab and ipilimumab (immunotherapy drugs) plus cabozantinib (a targeted anti-cancer drug) can shrink or control rare cancers of the urinary/reproductive system that have spread. It may help by boosting the immune system and blocking cancer growth signals at the same time.
Arroyo Grande, CaliforniaAges 18 years+ - NCT04981119Recruiting
Test apheresis for CAR T manufacturing in HLA-A2 solid tumors
This trial studies how a process called apheresis is used to make CAR T cells for people with certain solid tumors. It is designed for tumors that have lost a specific immune marker (HLA-A*02), which may affect how well CAR T therapies work.

What taking part in a malignant solid neoplasm study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
