Recruiting studies in California
- NCT06627647RecruitingPhase 3
Comparing two immunotherapy drugs for advanced lung cancer
This trial tests a new immunotherapy drug, rilvegostomig, against the standard pembrolizumab, both given with chemotherapy, as a first treatment for advanced non-squamous non-small cell lung cancer (NSCLC) that cannot be cured with surgery or radiation. It is for people whose tumors have high PD-L1 levels and do not have certain genetic mutations.

Gene therapy for HER2-positive cancer
This trial tests a new gene therapy for people with HER2-positive cancer. It is for two groups: those with advanced cancer that has worsened after treatment, and those with early-stage cancer at high risk of coming back. The goal is to see if the therapy can safely help shrink tumors or prevent return.

What taking part in a advanced or metastatic solid tumors 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.

- 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 advanced or metastatic solid tumors 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.
