Houston, TexasAges 18 years+ - NCT05010109Recruiting
Testing heart safety and fitness during lung cancer chemoradiation
This study looks at how lung cancer treatment affects the heart and whether a “walking test” and blood tests can track heart fitness and injury. It may help by improving how cancer therapy is planned and monitored for heart safety.
Houston, TexasAges 18 years+ - NCT05059678Recruiting
Parenting support for families facing advanced cancer
This study tests a program to help parents with advanced cancer support their children and manage family life during treatment. It may help you feel more confident as a parent while coping with cancer.

Common questions
- Are there clinical trials for questionnaire?
- Yes. Clin2 currently lists 1,134 recruiting questionnaire 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 questionnaire 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 questionnaire 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.
