We’re tracking 11 recruiting germ cell tumor studies with a site in California — including Early Phase 1, Phase 1, Phase 1/Phase 2, Phase 2 and Phase 3 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT07628634RecruitingEarly Phase 1
Testing a Low-Methionine Diet in Solid Tumor Patients
This early-stage study explores whether eating a diet low in methionine (a natural amino acid found in protein) might help people with advanced solid tumors. Researchers will track how this dietary change affects blood levels and may improve treatment outcomes alongside standard cancer care.
Orange, CaliforniaAges 18 years+ - NCT07218913RecruitingPhase 1
Testing a drug to reduce ear damage from chemo in testicular cancer
This trial tests whether adding Pedmark (sodium thiosulfate) to cisplatin chemotherapy can protect hearing in men with stage II or III testicular germ cell tumors. It aims to reduce the risk of drug-related ear damage while still treating the cancer.
Duarte, CaliforniaAges 18 years+ - NCT07164313RecruitingPhase 1
ZW251 for advanced solid tumors
This trial is testing a new drug called ZW251 for people with advanced liver cancer (hepatocellular carcinoma), non-small cell lung cancer, or germ cell tumors that have spread or cannot be removed by surgery. It aims to see if the drug is safe and effective.
San Francisco, CaliforniaAges 18 years+ - NCT06276491RecruitingPhase 1
Safety study of an investigational drug for advanced cancer with the CLDN6 marker
This trial tests an investigational drug for people with advanced solid tumors, especially ovarian, fallopian tube, peritoneal, endometrial, or germ cell cancers that have a specific marker called CLDN6. The goal is to see if the drug is safe and tolerable.
Duarte, CaliforniaAges 15 years+ - NCT06060873Recruiting
Using a blood test to find active germ cell tumors
This trial tests whether a blood test called miRNA-371 can detect active germ cell tumors in patients who have had surgery or are being watched. It may help guide treatment decisions without needing extra biopsies or scans.
Los Angeles, CaliforniaAges 18 years+ - 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 - NCT04684368RecruitingPhase 2
New treatment for children and young adults with a brain tumor
This trial tests a new treatment approach for a rare brain tumor called NGGCT. It aims to see if a different way of treating the tumor can be effective and safe for children and young adults.
Downey, CaliforniaAges 3–29 - NCT03067181RecruitingPhase 3
Active surveillance and chemotherapy for germ cell tumors
This study looks at how to manage germ cell tumors in children and young adults using careful monitoring for some patients and chemotherapy for others. It aims to see whether these approaches can control the cancer while avoiding unnecessary treatment when possible.
San Diego, CaliforniaAges Any age - NCT02582697RecruitingPhase 3
Faster vs standard chemotherapy for spreading germ cell tumors
This Phase 3 trial compares a faster chemotherapy approach versus the standard schedule for people with intermediate- or poor-risk metastatic germ cell tumors. The goal is to see which schedule works better and is safer enough to use as initial treatment.
Downey, CaliforniaAges 11–50 - NCT06646627RecruitingPhase 1
B7-H3 car t cells for platinum-resistant ovarian cancer
This trial tests a new treatment where your own immune cells are modified to attack ovarian cancer cells that have stopped responding to platinum chemotherapy. It's for people with recurrent ovarian cancer that hasn't gotten better with standard treatments.
Palo Alto, CaliforniaAges 18 years+ - NCT06427941RecruitingPhase 1/Phase 2
Study of BGB-B2033 with other drugs for advanced solid tumors
This study tests a new drug called BGB-B2033, alone or with other drugs (tislelizumab and bevacizumab), in people with certain advanced cancers. The goal is to see if this combination can shrink tumors or slow their growth, and to check its safety.

What taking part in a germ cell 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 germ cell tumor clinical trials in California?
- Yes. We're currently tracking 11 recruiting germ cell 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 germ cell 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 germ cell 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 germ cell 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.
