Silmitasertib plus chemo for relapsed solid tumors
This trial tests a new drug, silmitasertib, combined with standard chemotherapy for children and young adults with cancers that have come back or not responded to treatment. The goal is to see if this combination can shrink tumors or stop them from growing.
San Diego, CaliforniaAges Up to 30 years - NCT07169734RecruitingPhase 1/Phase 2
ALE.P03 for advanced CLDN1-positive solid tumors
This trial tests a new drug, ALE.P03, for people with advanced or metastatic solid tumors that have a certain protein (CLDN1). The drug is given alone (monotherapy) to see if it can shrink tumors or slow their growth.
Los Angeles, CaliforniaAges 18 years+ - NCT07488676RecruitingPhase 1/Phase 2
Study of ASP546C for stomach, pancreas, and other cancers
This trial tests a new drug called ASP546C in people with certain advanced cancers that have a specific marker (CLDN18.2). It aims to see if the drug can shrink or slow tumor growth.
Los Angeles, CaliforniaAges 18 years+ - NCT07432295RecruitingPhase 2
Givastomig plus nivolumab and chemo for advanced stomach cancer
This trial tests a new drug, givastomig, combined with standard immunotherapy (nivolumab) and chemotherapy for people with advanced stomach, gastroesophageal junction, or esophageal cancer. It is for people whose tumors have certain markers (CLDN18.2 and PD-L1) and who have not had treatment for advanced disease.
Duarte, CaliforniaAges 18 years+ - NCT07444814RecruitingPhase 1
HWK-007 for advanced solid tumors
This trial tests a new drug called HWK-007, which is designed to target and attack cancer cells while sparing healthy ones. It is for people with specific advanced solid tumors (lung, endometrial, or ovarian cancer) that have not responded well to standard treatments.
Los Angeles, CaliforniaAges 18 years+ - NCT07470853RecruitingPhase 1
Study of HWK-016 for advanced ovarian or endometrial cancer
This trial tests a new drug called HWK-016, which is designed to target and deliver medicine directly to cancer cells that have a specific marker (MUC16). It is for people with advanced ovarian or endometrial cancer to see if it can shrink tumors or slow their growth.
Los Angeles, CaliforniaAges 18 years+ - NCT07486713RecruitingPhase 4
Olutasidenib drug interaction study for IDH1 mutation cancers
This trial tests how olutasidenib interacts with other drugs in people with cancers that have an IDH1 mutation, like certain leukemias or brain tumors. Participation may help determine the best way to take this treatment safely.
Orange, CaliforniaAges 18 years+ - NCT05098132RecruitingPhase 1/Phase 2
STK-012 drug for advanced lung cancer and other tumors
This trial tests STK-012 (alone and with other treatments) in people with advanced cancers, especially non-small cell lung cancer. It may help by activating the immune system to recognize and fight the tumor.
Beverly Hills, CaliforniaAges 18 years+ - NCT06747585RecruitingPhase 1/Phase 2
ALE.P02 for advanced squamous cell cancers with CLDN1
This trial tests a new drug called ALE.P02 for people with advanced squamous cell cancers (like lung, head and neck, esophagus, or skin cancer) that have a certain protein called CLDN1. The drug is given alone and aims to shrink or stop the cancer.
Fullerton, CaliforniaAges 18 years+ - NCT05377996RecruitingPhase 1/Phase 2
Study drug for advanced solid tumors with tumor tissue testing
This early-stage study tests emiltatug leda-dotin (Emi-Le) in people with advanced or recurring solid cancers. It aims to see how the drug works and how safely it can be given, using tumor tissue testing to help understand who may benefit.
Santa Monica, 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.

What taking part in a solid tumor 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.

Common questions
- Are there solid tumor clinical trials in California?
- Yes. We're currently tracking 328 recruiting solid tumor studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a solid tumor study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a solid tumor trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
Not the right time?
New solid tumor studies open in California regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
