The study will test an investigational drug known as 4D-710. An "investigational drug" is one that has not yet been approved for use by a Health Authority such as the United States Food and Drug Administration (FDA). 4D-710 is being studied as a potential treatment for cystic fibrosis lung disease. This is the first study to test 4D-710 in humans. The purpose of this study is to see if 4D-710 is safe for use in adults with cystic fibrosis and to see if 4D-710 can help lung function.

A 144-week clinical research study to look at how well an investigational obesity medicine works, along with a reduced-calorie diet and increased physical activity in participants with obesity.
The medicines are injected subcutaneously (under the skin) once a week.
This study also includes a placebo.

This study is being conducted to evaluate the drug AZD0292, including how safe it is, how long it stays in the blood, and if it may help in reducing the number of exacerbations in people with Pseudomonas aeruginosa in their lungs. These patients have more frequent lung exacerbations and reduced quality of life. Pseudomonas aeruginosa is a bacteria that can make the symptoms of bronchiectasis worse. The study drug (AZD0292) works by attaching to Pseudomonas aeruginosa, thereby reducing its effects on the lungs and improving symptoms.
This study aims not only to test AZD0292 but is also being done to better understand bronchiectasis disease and its associated health problems.
Study drug (AZD0292) or placebo, will be given to participants as an intravenous (IV) infusion. The study is double-blinded.
About 435 participants with bronchiectasis 12 years of age and older, weighing at least 35kg will take part in this study. This study will be conducted globally in approximately 25 countries.
