Los Angeles, CaliforniaAges 18 years+ - NCT04734730RecruitingPhase 2
Talazoparib plus hormone therapy for metastatic prostate cancer
This trial tests whether talazoparib added to standard hormone therapy (ADT), along with abiraterone, can better control metastatic prostate cancer that hasn’t progressed despite starting hormone treatment. It may help people live longer and delay cancer worsening.
Duarte, CaliforniaAges 18 years+ - NCT04752722RecruitingPhase 1/Phase 2
Gene therapy for bladder cancer that came back after BCG
This study tests a new gene therapy (EG-70) given directly into the bladder for people with a high-risk bladder cancer called NMIBC. It may be an option if BCG treatment stopped working, or if you cannot have or choose not to have bladder removal surgery.
Irvine, CaliforniaAges 18 years+ - NCT04628767RecruitingPhase 2/Phase 3
Durvalumab plus chemo before surgery for upper tract cancer
This trial tests whether adding an immunotherapy drug (durvalumab) to chemotherapy before surgery can improve outcomes for people with high-grade upper tract urothelial cancer. It compares different treatment approaches based on whether a patient can receive cisplatin chemotherapy.

What taking part in a carcinoma 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 carcinoma clinical trials in California?
- Yes. We're currently tracking 469 recruiting carcinoma 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 carcinoma 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 carcinoma 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.
