Brief Summary

The main goal of this pharmacokinetic study in healthy volunteers is to evaluate the potential effect of cyclosporine (probe inhibitor of P glycoprotein \[P-gp\] and breast cancer resistance protein \[BCRP\] transporters) on CHF6001 (Tanimilast) systemic exposure following single dose administration, by comparing the area under the curve (AUC) from time 0 to the last quantifiable concentration (AUC0 t) and the maximum plasma concentration (Cmax) of CHF6001 with and without cyclosporine. Participants will receive CHF6001 alone in Treatment Period 1, then CHF6001 after oral cyclosporine in Treatment Period 2, in order to evaluate the cyclosporine drug interaction on CHF6001 systemic exposure. The two treatment periods will be separated by a wash out period of 14 to 17 days.

• Body mass index between 18.0 and 30.0 kg/m2 extremes inclusive;
• Non- or ex smokers who smoked \<5 pack years;
• Good physical and mental status determined based on the medical history and a general clinical examination, at the Screening Visit and prior to the first dosing;
• Vital signs within normal limits at the Screening Visit;
• A 12-lead digitalised electrocardiogram (12-lead ECG) in triplicate considered as normal at the Screening Visit;)
• Pulmonary function test within normal limits at the Screening Visit;
• Males fulfilling one of the following criteria:
• Males with pregnant or non-pregnant women of childbearing potential (WOCBP) partners: They must be willing to use male condom from the signature of the informed consent and until the Follow up Call; or
• Non fertile male subjects: Contraception is not required in this case; or
• Males with women of non childbearing potential (WONCBP) partners: Contraception is not required in this case;
• Females fulfilling one of the following criteria:
• WONCBP defined as physiologically incapable of becoming pregnant. Tubal ligation or partial surgical interventions are not acceptable. If indicated, as per Investigator's request, post menopausal status may be confirmed by follicle stimulating hormone levels;

You may not qualify if:

• Participation in another clinical study less than 8 weeks prior to the Screening Visit;
• Clinically relevant and uncontrolled respiratory, cardiac, hepatic, gastrointestinal, renal, endocrine, metabolic, neurologic or psychiatric disorders, gastric surgery recently or in the past, and/or impaired gastric motility that may interfere with successful completion of this protocol according to the Investigator's judgment;
• Clinically relevant abnormal laboratory values at the Screening Visit suggesting an unknown disease and requiring further clinical investigation, or which may impact the safety of the subject or the evaluation of the results of the study according to the Investigator's judgment.
• Abnormal liver enzymes at the Screening Visit (alanine aminotransferase or aspartate aminotransferase \>1.5x upper limit of normal \[ULN\], bilirubin \>1.5x ULN).
• Subjects with history of breathing problems (e.g. history of asthma). Allergic asthma diagnosis in childhood (until 12 years old) is allowed;
• Positive human immunodeficiency virus (HIV) 1 or HIV2 serology at the Screening Visit;
• Positive results from the hepatitis serology which indicates acute or chronic hepatitis B (HB) or hepatitis C (HC) at the Screening Visit;
