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.
San Francisco, CaliforniaAges 18 years+ - NCT07164027RecruitingEarly Phase 1

Los Angeles, CaliforniaAges 18–90 - NCT07174388Recruiting
Study comparing treatments for advanced lung cancer using medical records

Monterey, CaliforniaAges 18 years+ - NCT07181161RecruitingPhase 1/Phase 2
Testing a new drug for metastatic prostate cancer
This trial tests an investigational drug (AZD0516) alone or with other treatments in men with prostate cancer that has spread to other parts of the body and is no longer responding to hormone therapy. It aims to see if the drug can help control the cancer.

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 1,311 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.
