Recruiting studies in California
- NCT06586957RecruitingPhase 1
Study of NKT3964 for advanced solid tumors
This trial tests an experimental drug called NKT3964 for people with certain advanced cancers that have stopped responding to standard treatments. It aims to see if the drug can shrink tumors or slow their growth.

TR-002 for advanced solid tumors and pancreatic cancer
This trial tests a new drug called TR-002 in people with advanced solid tumors (cancer that has spread) who have run out of standard treatment options. It includes a specific group for people with pancreatic cancer that is no longer responding to chemotherapy.
Sacramento, CaliforniaAges 18 years+ - NCT06942104RecruitingPhase 1
New imaging agent for advanced solid tumors
This trial tests a new imaging agent (18F-TRX) to see if it can better detect cancer spread in people with advanced solid tumors.

Adding a new drug to capecitabine for metastatic colorectal cancer
This Phase 1 study tests a new anti-cancer drug (ZEN003694) added to the usual chemotherapy capecitabine. It is for adults with colorectal cancer (and possibly other cancers) that has spread or cannot be removed and has continued despite prior standard treatment.
Orange, CaliforniaAges 18 years+ - NCT05733949RecruitingEarly Phase 1

This trial tests a precise type of radiation that targets multiple tumor spots in a carefully planned way. It may help people with many metastatic (spread) solid tumors when standard treatments aren’t working or can’t be used.
Duarte, CaliforniaAges 18 years+ - NCT05687110RecruitingPhase 1
Testing novobiocin for tumors with DNA repair gene changes
This Phase 1 study tests whether novobiocin is safe and finds the best dose for people whose tumors have specific DNA repair gene mutations. It may help if your cancer is hard to treat with standard options, including certain patients who already tried PARP inhibitors.
San Diego, CaliforniaAges 18 years+ - NCT05691491RecruitingPhase 1/Phase 2
Temozolomide plus M1774 for advanced metastatic cancers
This Phase 1/2 trial tests a combination of temozolomide and M1774 to see how safe it is and whether it can help shrink advanced cancers that have spread. It focuses on certain tumor types and specific biomarker results, and it may be an option if standard treatments have been tried or aren’t possible.
Orange, CaliforniaAges 18 years+ - NCT05564377RecruitingPhase 2
Find targeted cancer treatments using genetic testing
This study matches people with advanced solid tumors to targeted treatment plans based on genetic testing. It also requires tumor sample testing to help doctors choose the most promising therapy for your specific tumor changes.
Arroyo Grande, CaliforniaAges Any age - NCT05372640RecruitingPhase 1
Drug combo trial for rare cancers with shared NUT features
This Phase 1 trial tests the safety and early signs of effectiveness of combining two anti-cancer drugs (ZEN003694 and abemaciclib) in teens and adults with metastatic or unresectable NUT carcinoma, breast cancer, and other solid tumors. It may help by finding a safer dose and whether the drug combination can shrink or control tumors that do not respond to standard treatments.
Los Angeles, CaliforniaAges 12 years+ - NCT05372614RecruitingPhase 1
Testing trastuzumab deruxtecan and neratinib for HER2-positive cancers
This trial tests a combination of two targeted drugs, trastuzumab deruxtecan (Enhertu) and neratinib, for people with solid tumors that have a HER2 gene change. The goal is to see if the combination is safe and works well for cancers that have not responded to at least one prior treatment.
Duarte, CaliforniaAges 18 years+ - NCT05371132RecruitingPhase 1
PET scan study to track immune response after SBRT
This early (Phase 1) study uses a special PET scan to measure how your immune system responds after stereotactic body radiation therapy (SBRT). The goal is to see whether the scan result can serve as a marker of immune response, which may help future treatment planning.
Duarte, CaliforniaAges 18 years+ - NCT04870944RecruitingPhase 1/Phase 2
CBL0137 for children with advanced solid or brain tumors
This early-phase study tests CBL0137 in children and teens whose cancer has come back or is not responding to treatment. It is also for some specific hard-to-treat brain tumors, to see if the drug is safe and can work against the cancer.
Los Angeles, CaliforniaAges 1–21 - NCT04901702RecruitingPhase 1/Phase 2
Onivyde plus talazoparib or temozolomide for resistant solid tumors
This trial tests whether adding Onivyde to either talazoparib or temozolomide can shrink or control hard-to-treat (refractory or recurring) cancers in children and young adults. It aims to find safer dosing first, then look at how well the treatment works—especially for Ewing sarcoma.
Palo Alto, CaliforniaAges 1–30 - NCT04851119RecruitingPhase 1/Phase 2
Tegavivint for kids and young adults with hard-to-treat solid tumors
This early-phase study tests tegavivint to see how well it works and how safe it is for children and young adults with solid cancers that have come back or are not responding. It may be an option if your tumor type (including certain lymphomas or desmoid tumors) matches the study’s rules.
Palo Alto, CaliforniaAges 1–30 - NCT04678648RecruitingPhase 1
Testing RSC-1255 in advanced cancers with RAS changes
This early study (Phase 1) tests a new drug, RSC-1255, in people with advanced or metastatic cancers that have RAS mutations. It’s mainly focused on whether the treatment can be given safely and at what dose, and to see if it may shrink tumors.
Los Angeles, CaliforniaAges 18 years+ - NCT04585750RecruitingPhase 1/Phase 2
Studying a new drug for cancers with a specific TP53 change
This trial tests a new drug (rezatapopt) for people with advanced cancers that have a specific change in the TP53 gene, called Y220C. The drug is designed to target this change and may slow or stop cancer growth. Some participants may also receive an immunotherapy drug called pembrolizumab (Keytruda).
Irvine, CaliforniaAges 12 years+ - NCT04329494RecruitingPhase 1
Study of targeted drug delivery into the abdomen using PIPAC
This Phase 1 trial tests PIPAC, a way to deliver anti-cancer medicine directly into the abdomen using a minimally invasive procedure. It is for people with peritoneal spread from certain cancers to see whether this approach is safe and potentially helpful.
Duarte, CaliforniaAges 18 years+ - NCT04119024RecruitingPhase 1
Gene-edited immune cells for advanced melanoma or solid tumors
This Phase 1 study tests a gene-modified immune cell treatment for advanced cancers that don’t have standard curative options. It may help by attacking cancer cells that show a specific marker called IL13Rα2 after patients receive “conditioning” chemotherapy to prepare the immune system.
Stanford, CaliforniaAges 18–75 - 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+ - NCT03816345RecruitingPhase 1
Nivolumab for advanced cancer with autoimmune disease
This trial tests whether the immunotherapy drug nivolumab can safely treat advanced cancer in people who also have an autoimmune disease like rheumatoid arthritis, lupus, or multiple sclerosis. It aims to find out if the drug may help control cancer while managing their autoimmune condition.

What taking part in a metastatic 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.
