The criterion should be specified during the randomization visit. * The presence of hemoptysis at the time of inclusion in the study. * The presence of diseases of the respiratory tract, in addition to bronchiectasis, which can affect the effectiveness of the study drug and patient safety.

The corrected QT interval (QTc) interval on the electrocardiogram (ECG in 12 leads) is more than 450 ms for men and more than 470 ms for women on screening and randomization visits. * A history of hypersensitivity to any of the substances used in the study. * Clinically significant deviations of laboratory parameters, indicating a significant or unstable concomitant disease, which may affect the effectiveness of the study drug or patient safety. * Hemostasis deviation within 1 month before the first inhalation of the study drug, including confirmed: * Hemoglobin \<10 g / 100 ml; * White blood cell count \<3.0 x 10\*9 / L; * The absolute number of neutrophils ≤ 1.5 x 10\*9 / L; * Platelet count \<100 x 10\*9 / L. * Unstable concomitant disease, such as uncontrolled hyperthyroidism, uncontrolled diabetes or other endocrine diseases; significant impairment of liver and kidney function; uncontrolled gastrointestinal diseases (for example, active peptic ulcer); uncontrolled neurological diseases; uncontrolled hematological diseases; uncontrolled autoimmune diseases or other diseases that, according to the researcher, may affect the effectiveness of the study drug and patient safety. * Alcohol and/or drugs abuse 12 months before screening visit. * Failure to perform tests to evaluate external respiration function, perform research procedures, or adhere to the treatment schedule provided for in the study. * Participation in another clinical trial in which the study drug was administered less than 8 weeks before the screening visit. Exclusion criteria: * Informed consent withdrawn by the patient. * The patient doesn't follow the instructions of the research staff regarding the requirements of the research protocol. * Unable to contact patient. * The researcher believes that participation in the study is not in the interests of the patient and / or further participation in the study is unsafe for the patient's health. * There is a violation of the criteria for inclusion and / or non-inclusion in the study. * The patient has developed adverse event, which, according to the researcher, makes further participation in the study unsafe for the patient. * The licensing authority or ethics committee, for any reason, decides to discontinue the entire study or close this research center. * A female patient becomes pregnant, is planning a pregnancy, or is breastfeeding while participating in this study.
