Clinical Trial Summary

The purpose of this study is to investigate 5 doses of RPL554 and placebo, administered by dry powder inhaler (DPI), in patients with moderate to severe chronic obstructive pulmonary disease (COPD).

Description:

The study will consist of two parts. Part A is a parallel group, placebo-controlled single dose study to ascertain the Pharmacokinetics (PK) profile, safety and bronchodilator effect of RPL554 administered via dry powder inhaler (DPI). Five of the 6 treatment arms will be double-blind and one will be single-blind (due to the different number of capsules administered). Part B is a placebo-controlled, complete block cross-over, repeat dose study to assess the bronchodilator effect of repeat doses of RPL554 delivered via a DPI.

16. A disclosed history or one known to the Investigator, of significant non compliance in previous investigational studies or with prescribed medications.

17. Required use of oxygen therapy, even on an occasional basis.

18. History of malignancy of any organ system within 5 years, with the exception of localized skin cancers (basal or squamous cell).

19. Clinically significant abnormal values for safety laboratory tests (hematology, biochemistry, viral serology or urinalysis) at Screening, as determined by the Investigator. In particular, alanine aminotransferase or aspartate aminotransferase cannot be more than twice the upper limit of normal.

20. Any other reason that the Investigator considers makes the patient unsuitable to participate.
