Summary

This is a prospective, single-center, open-label clinical study designed to evaluate the safety, tolerability, and preliminary efficacy of inhaled BMD003 (CFTR mRNA) in Chinese patients aged 12 years and above with cystic fibrosis (CF) following multiple administrations. Additionally, the study aims to explore the pharmacokinetic characteristics, immunogenicity, and relevant biomarkers of the drug.

The study adopts a multiple-dose escalation design. Eligible patients will be sequentially enrolled into different cohorts, and the next cohort may receive a higher dose only after the safety data review of the previous dose cohort is completed. The entire study consists of four phases: screening period, safety observation period, continuous treatment period, and long-term follow-up period. Participants will receive nebulized inhalation of the study drug at the specified frequency. During the study, blood, sputum samples, and nasal swabs will be collected at designated time points for pharmacokinetic, immunogenicity, cytokine, and other related detections. Moreover, lung function tests, chest imaging, electrocardiograms, sweat chloride concentration tests, and other examinations will be performed at each visit. Meanwhile, the Cystic Fibrosis Questionnaire-Revised (CFQ-R) will be used to assess the patients' health-related quality of life, so as to comprehensively evaluate the safety and efficacy of the study drug.

Adverse events will be closely monitored and recorded throughout the study. The safety of the study drug will be comprehensively evaluated by summarizing various safety indicators such as adverse events and laboratory tests. All statistical analyses will be performed using professional statistical software, and descriptive statistical methods will be employed to analyze the safety, efficacy, pharmacokinetic, and other related data of the study drug. The total duration of this study is 1 year, which is intended to provide a basis for the selection of the recommended dose for Phase Ⅱ clinical trials.

Conditions

Interventions

DRUG

BMD003 (CFTR mRNA)

Nebulized inhalation of BMD003 (CFTR mRNA) lyophilized preparation. The drug is reconstituted with sterile water for injection to the required concentration before use. Participants receive weekly administration for 12 consecutive weeks. Prior to each administration, airway clearance therapy (e.g., active cycle of breathing technique) is performed as standard care, with short-acting bronchodilators permitted if clinically indicated.
