Eligibility Criteria:
Inclusion Criteria:~1. Sign an informed consent document indicating they understand the purpose of and procedures required for the study and are willing to participate in the study.~2.

Body mass index (BMI) between 18 and 35 kg/m2 (inclusive) with a minimum weight of 45 kg.~6. COPD diagnosis for 1 year \[prior to screening~7. Ability to perform acceptable and reproducible spirometry.~8. Post-bronchodilator (four puffs of albuterol) spirometry at Screening demonstrating the following:~   * FEV1/Forced Vital Capacity (FVC) ratio of ≤0.70~  * FEV1 ≥40 % and ≤80% of predicted normal~  * ≥150 mL increase from pre-bronchodilator FEV1~9. Clinically stable COPD in the 4 weeks prior to Screening and during the period between Screening and Part A.~10. A chest X-ray showing no abnormalities, which are both clinically significant and unrelated to COPD.~11. Meet the concomitant medication restrictions and be expected to do so for the rest of the study.~12. Current and former smokers with smoking history of ≥10 pack years. 14. Capable of withdrawing from long acting bronchodilators for the duration of the study, and short acting bronchodilators for 8 hours prior to dosing.~Exclusion Criteria:~1. A history of life-threatening COPD including Intensive Care Unit admission and/or requiring intubation.~2. COPD exacerbation requiring oral or parenteral steroids, or lower respiratory tract infection requiring antibiotics, within 3 months of Screening or prior to Part A.~3. A history of one or more hospitalizations for COPD or pneumonia within 6 months of Screening or prior to Part A.~4. Intolerance or hypersensitivity to tiotropium, olodaterol, atropine, ipratropium, or RPL554.~5. Evidence of cor pulmonale or clinically significant pulmonary hypertension.~6. Other respiratory disorders~7. Previous lung resection or lung reduction surgery.~8. Use of immunosuppressive therapy, including oral corticosteroids~9. Pulmonary rehabilitation, unless such treatment has been stable from 4 weeks prior to Screening and remains stable during the study.~10. History of, or reason to believe a patient has, drug or alcohol abuse within the past 5 years.~11. Received an experimental drug within 30 days or five half lives, whichever is longer.~12. Patients with uncontrolled disease including, but not limited to, endocrine, active hyperthyroidism, neurological, hepatic, gastrointestinal, renal, hematological, urological, immunological, psychiatric, or ophthalmic diseases that the Investigator believes are clinically significant.~13. Documented cardiovascular disease, including any history of arrhythmias, angina, recent (\<1 year) or suspected myocardial infarction, congestive heart failure, unstable or uncontrolled hypertension, or diagnosis of hypertension within 3 months prior to Screening~14. Use of non-selective oral β-blockers.~15. Major surgery (requiring general anesthesia) within 6 weeks prior to Screening, lack of full recovery from surgery at Screening, or planned surgery through the end of the study.~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.
