NCT05543343

Brief Summary

It is planned to enroll 495 acute exacerbation of chronic obstructive pulmonary disease patients, and they will be randomly assigned to the high-dose test group, normal dose test group or control group at a ratio of 1:1:1, with 165 patients in each group. The course of treatment is 90 days, and the total follow-up time is one year. The purpose of the study is to evaluate the effectiveness and safety of different doses of bacterial lysates (Staphylococcus and Neisseria Tablets) in the treatment of acute exacerbation of chronic obstructive pulmonary disease.

  • The patient was in the acute exacerbation of chronic obstructive pulmonary disease at the time of enrollment (the patient's cough, sputum expectoration, and dyspnea exceeded any abnormal variation);
  • At least one exacerbation of chronic obstructive pulmonary disease in the past year; The patient (or his legal representative) must sign and date the informed consent form, indicating that he/she understands the purpose of the study and the procedures to be carried out, and is willing to participate in the study.
