Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This study is a randomized, double-blind, placebo-controlled study designed to assess the efficacy and safety of ensifentrine inhalation suspension (3 mg) delivered twice daily via standard jet nebulizer over at least 24 weeks, compared to placebo, in subjects with non-cystic fibrosis bronchiectasis (NCFBE).

Notes: If a subject has no clinical history consistent with bronchiectasis, they may not be re-screened. * Current sputum producer with a history of chronic expectoration and able to provide sputum sample spontaneously at the clinic during screening. * ≥ 1 documented pulmonary exacerbation defined by an antibiotic prescription by a physician for the signs and symptoms of respiratory infections in the past 12 months before screening. * Capable of using the study nebulizer correctly. * Ability to perform acceptable spirometry in accordance with American Thoracic Society and European Respiratory Society guidelines	* A diagnosis of COPD or a primary diagnosis of asthma, as judged by the investigator. * Bronchiectasis due to cystic fibrosis, hypogammaglobulinemia common variable immunodeficiency, severe immunodeficiency, or requirement for treatment with intravenous immunoglobulin. * Current smoker defined as by the Centers for Disease Control and Prevention (CDC). * Former cigarette smokers with a history of cigarette smoking ≥ 10 pack years at Screening \[number of pack years = (number of cigarettes per day / 20) × number of years smoked (e.g., 20 cigarettes per day for 10 years, or 10 cigarettes per day for 20 years)\]. Pipe and/or cigar use cannot be used to calculate pack-year history. Former smokers are defined as those who have stopped smoking for at least 6 months prior to Screening. * A diagnosis of primary ciliary dyskinesia. * Current treatment for nontuberculous mycobacterial lung infection, allergic bronchopulmonary aspergillosis, or tuberculosis. * Presence of acute exacerbation or another acute infection that required antibiotic treatment within 4 weeks of screening (or within 12 weeks of screening if the antibiotic prescription is a macrolide). * Use of the following prohibited medications within the designated time periods: 1. Immunomodulatory agents (e.g., bortezomib, ixazomib, thalidomide, dupilumab) within 3 months prior to signing the ICF. 2.

Theophylline and PDE4 inhibitors (e.g., roflumilast, apremilast, crisaborole) within 48 hours prior to signing the ICF. 5. Brensocatib within 3 months or 5 half-lives, whichever is longer, prior to signing the ICF. 6.

Note: Chronic stable hepatitis B and C is not exclusionary if the subject otherwise meets study entry criteria. * History of or current malignancy of any organ system, treated or untreated within the past 5 years, except for localized basal or squamous cell carcinoma of the skin. * Estimated glomerular filtration rate (eGFR) \< 30 mL/min. * Alanine aminotransferase (ALT) ≥ 2 × upper limit of normal (ULN), aspartate aminotransferase (AST) ≥ 2 × ULN, alkaline phosphatase and/or bilirubin \> 1.5 × ULN (isolated bilirubin \> 1.5 × ULN is acceptable if fractionated bilirubin \< 35%). * Participation in any other interventional, clinical studies (drugs or devices) within 3 months before Day 1, or 5 half-lives, whichever is longer. * Intolerance of or hypersensitivity to ensifentrine or any of its excipients/components. * Current or history of drug or alcohol abuse within the past 5 years. * Significantly abnormal ECG finding
