Study summary

The primary objectives of this study:

  • To investigate the safety and tolerability of ascending repeated oral doses of BAY1902607 in healthy subjects (Part 1).
  • To investigate the effect of BAY1902607 on the pharmacokinetics (PK) of a sub-therapeutic 1 mg dose of midazolam (Part 1).
  • To investigate the safety, tolerability and efficacy of BAY1902607 in patients with refractory chronic cough (Part 2).

[Acceptable methods of contraception include for example: (a) condoms (male or female) with or without a spermicidal agent, (b) diaphragm or cervical cap with spermicide, (c) intrauterine device, (d) hormone-based contraception]

Part 2:

  • Age: ≥18 years at the first screening visit
  • Refractory chronic cough for at least one year that has been shown to be unresponsive to treatment of cough according to the 2006 British Thoracic Society (BTS) guideline
  • Score of ≥ 40 mm on the Cough Severity visual analogue scale (VAS) at screening
  • For female patients:

Confirmed post-menopausal woman (defined as exhibiting spontaneous amenorrhea for at least 12 months before screening or as exhibiting spontaneous amenorrhea for 6 months before screening with documented serum follicle-stimulating hormone (FSH) levels > 40 mIU/mL) or Woman without childbearing potential based on surgical treatment at least 6 weeks before screening, such as bilateral tubal ligation, bilateral oophorectomy with or without hysterectomy (documented by medical report verification) or Woman of childbearing potential that agrees to use two reliable and acceptable methods of contraception simultaneously (one method used by the study patient and one method used by the partner) during the study and for at least 31 days (1 average menstrual cycle of 28 days plus approx. 5 half-lives of BAY 1902607) after the last dose. In addition during the study and for at least 31 days after the last dose women of child bearing potential are not allowed to donate oocytes.

Part 2:

  • FEV1(Forced Expiratory Volume in 1 second) or FVC(Forced Vital Capacity ) of less than 60% of predicted normal, at screening
  • History of upper or lower respiratory tract infection or recent significant change in pulmonary status within the 4 weeks before screening
