CayenneAges 18 years+ - NCT06928922RecruitingEarly Phase 1
Inhaled mRNA vaccine for advanced lung cancer and lung metastases
This trial tests an inhaled dry powder vaccine that uses mRNA to help your immune system target cancer cells in the lungs. It is for people with advanced lung cancer or solid tumors that have spread to the lungs, who have already tried standard treatments.
BeijingAges Up to 99 years - NCT06718127Recruiting

Common questions
- Are there clinical trials for vaccination?
- Yes. Clin2 currently lists 575 recruiting vaccination studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a vaccination trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a vaccination trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
