Understanding bronchiectasis subtypes for better treatment
This study helps doctors identify different types of bronchiectasis (a lung disease where airways are permanently widened and damaged) to better understand how the disease develops and progresses. By following patients over time and collecting medical information, researchers hope to create a system that predicts which patients will worsen and need different treatments.

Predicting ABPA Recurrence Using Blood and Immune Markers
This study helps doctors predict whether allergic bronchopulmonary aspergillosis (ABPA)—a serious lung condition caused by fungal allergy—will come back after treatment. Researchers will analyze blood samples and immune system markers to identify patients at higher risk of relapse, which could improve how doctors monitor and treat you.
Jinan, ShandongAges 18–80 - NCT07627763Recruiting
Understanding COPD patterns and how your lungs change over time
This study follows people with stable COPD to learn how the disease progresses and affects different patients in different ways. Researchers will track your lung function and symptoms over time to better understand COPD and improve treatment.

Common questions
- Are there clinical trials for phenotype?
- Yes. Clin2 currently lists 315 recruiting phenotype 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 phenotype 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 phenotype 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.
