Recruiting studies in California
- NCT07198074RecruitingPhase 3
Testing Avastin added to chemo plus Keytruda for certain endometrial cancer
This study tests adding Avastin (bevacizumab) to the standard combination of chemotherapy (carboplatin and paclitaxel) plus immunotherapy (Keytruda) for advanced or recurrent endometrial cancer with a specific genetic makeup (pMMR and TP53 mutation). The goal is to see if adding Avastin helps shrink tumors or slow their growth.

PET Scan for Prostate Cancer Recurrence After Focal Therapy
This study uses a special PET/CT scan (Flotufolastat F 18) to look for leftover or returning prostate cancer after you've had a targeted treatment called focal therapy. The goal is to see if the scan can help find cancer that might need further treatment.
Los Angeles, CaliforniaAges 18–90 - NCT07189195RecruitingPhase 1
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.

Clovis, CaliforniaAges 18 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+ - NCT05836688Recruiting

This trial tests a new experimental drug called PF-08046054/SGN-PDL1V against a standard chemotherapy (docetaxel) for people with a type of advanced lung cancer that has PD-L1 protein on at least 1% of tumor cells and has progressed after prior treatments. The goal is to see if the new drug works better or has fewer side effects.
Berkeley, CaliforniaAges 18 years+ - NCT07140900RecruitingPhase 1
Study of xaluritamig combined with hormone therapy for advanced prostate cancer
This trial tests a new drug, xaluritamig, given with standard hormone therapy for men with prostate cancer that has spread to other parts of the body (metastatic) and is still sensitive to hormone therapy. It aims to see if the combination is safe and works better than hormone therapy alone.

What taking part in a cancer 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 cancer clinical trials in California?
- Yes. We're currently tracking 1,320 recruiting cancer 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 cancer 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 cancer 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 cancer 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.
Clin2 helps you find and understand clinical trials and does not provide medical advice. Study data comes from ClinicalTrials.gov. Talk with your doctor about whether a specific trial is right for you.
