Brief summary

CHF 6333 is a medicinal product on development for the treatment of cystic fibrosis and non-CF bronchiectasis and undergoing clinical testing. It has not yet been approved by the authorities for the treatment of these diseases. CHF6333 is an inhaled anti-inflammatory which mechanism of action is based on the inhibition of Human Neutrofil Elastase. The safety and tolerability of single and repeated ascending doses of inhaled CHF 6333 was previously investigated in healthy subjects: information was gathered on the uptake, distribution and excretion of the medicinal product being tested (pharmacokinetics). In this current clinical trial CHF 6333 will be tested in patients(CF and NCFB) for the first time. Three dose level will be tested during the first part of the study, as single administration. One repeated dose will be administered in the second part of the study.

Exclusion criteria

CF Patients * Patient with BMI ≤ 17 * History of a clinically meaningful unstable or uncontrolled chronic comorbidity in the opinion of the Investigator; * Unstable pulmonary status or symptomatic respiratory tract infection and related changes in therapy for pulmonary disease as per Investigator's judgment within 4 weeks before screening or prior to randomisation; * Abnormal and clinically significant 12-lead ECG at screening or prior to randomisation; * History of asthma based on objective evidence; * History of malignancy, solid organ/haematological transplantation; * Patient with evidence of active Nontuberculous Mycobacteria (NTM) and Tuberculous Mycobacteria (TM) infection or related bronchiectasis in the past 12 months; * Patient with a positive test for active Allergic Bronchopulmonary Aspergillosis (ABPA) infection confirmed at screening or patient withABPA related bronchiectasis. * Pregnant or lactating women. * Patient on non-steroidal anti-inflammatory drugs (NSAIDs) within 4 weeks prior to screening or prior to randomization visit. * Patient on cystic fibrosis transmembrane conductance regulator (CFTR) modulators and correctors if not on stable treatment regimen for at least 3 months prior to screening or prior to randomization. * Positive HIV1 or HIV2 serology at screening; Positive results from the Hepatitis serology which indicates acute or chronic Hepatitis B or Hepatitis C at screening (i.e. positive HB surface antigen (HBsAg), HB core antibody (anti-HBc), HC antibody); NCFB Patients * Patient with BMI ≤ 17 * History of a clinically meaningful unstable or uncontrolled chronic comorbidity in the opinion of the Investigator; * Unstable pulmonary status or symptomatic respiratory tract infection and related changes in therapy for pulmonary disease as per Investigator's judgment within 4 weeks before screening or prior to randomisation. * Abnormal and clinically significant 12-lead ECG at screening or prior to randomisation that results in active medical problem which may impact the safety of the patients as per Investigator's judgment. * History of malignancy, solid organ/haematological transplantation; * Known diagnosis of cystic fibrosis.
