9. The participant must have pulmonary function at the time of screening meeting both of
the following:
1. Post-bronchodilator forced expiratory volume in 1 second (FEV1) greater than or
equal to (> or =) 50 percentage (%) of predicted.
2. If FEV1 is >80% predicted, then FEV1/forced vital capacity (FVC) must be <0.7.
*Note: Inclusion criterion #1a, #9a and #9b are not applicable to participants
who are not required to undergo the bronchoscopy/BAL procedures.
Exclusion Criteria:
1. The participant is experiencing or has a history of clinically significant pulmonary
disease (other than chronic obstructive pulmonary disease (COPD), emphysema, chronic
bronchitis, mild bronchiectasis, and stable asthma).

4. The participant has a history of frequent pulmonary exacerbations (greater than 2
moderate or severe exacerbations within 52 weeks prior to screening.
5. The participant is experiencing a pulmonary exacerbation at the time of screening
(participant may be rescreened 4 weeks after the clinical resolution of an
exacerbation).
6. The participant has clinically significant abnormalities (other than emphysema,
chronic bronchitis, or mild bronchiectasis) detected on chest X-ray or CT scan at the
time of screening (past records obtained within 52 weeks prior to screening may be
used, if available).
7. The participant has clinically significant abnormalities detected on a 12-lead
electrocardiogram (ECG) performed at the time of screening (past records obtained
within 26 weeks prior to screening may be used, if available).
8. The participant has clinically significant congestive heart failure with New York
Heart Association (NYHA) Class III/IV symptoms.
9. The participant is experiencing an active malignancy or has a history of malignancy
within 5 years prior to screening, with the exception of the following: adequately
treated basal cell or squamous cell carcinoma of the skin, carcinoma in situ of the
cervix, or stable prostate cancer not requiring treatment.
10. The participant has a history of lung or other organ transplant, is currently on a
transplant list, or has undergone major lung surgery.
11. The participant is receiving long-term around-the-clock oxygen (O2) supplementation.
(The following are allowed: short-term use of oxygen supplementation [eg, for the
management of acute COPD exacerbation], O2 supplementation required during night time
only, and supplemental O2 with continuous positive airway pressure [CPAP] or bi-level
positive airway pressure [BiPAP]).
12. Known history of hypersensitivity following infusions of human blood or blood
components.
13. Immunoglobulin A (IgA) deficiency (<8 milligram per deciliter (mg/dL) at screening).
14. Abnormal clinical laboratory results obtained at the time of screening meeting any of
the following criteria:
1. Serum alanine aminotransferase (ALT) >3.0 times upper limit of normal (ULN)
2. Serum total bilirubin >2.0 times ULN
3. >2+proteinuria on urine dipstick analysis
4. Serum creatinine >2.0 times ULN
5. Absolute neutrophil count (ANC) <1500 cells per cubic millimeter (cells/mm^3)
6. Hemoglobin (Hgb) <9.0 gram per deciliter (g/dL)
7. Platelet count <100,000/cubic millimeter (mm^3)
15. Ongoing active infection with hepatitis A virus (HAV), hepatitis B virus (HBV),
hepatitis C virus (HCV), or human immunodeficiency virus (HIV) Type 1 or 2 infection

16. The participant has any clinically significant medical, psychiatric, or cognitive
illness, or any other uncontrolled medical condition (eg, unstable angina, transient
ischemic attack) that, in the opinion of the investigator, would impede the
participant's ability to comply with the study procedures, pose increased risk to the
participant's safety, or confound the interpretation of study results.
17. The participant has participated in another clinical study involving an IP or
investigational device within 30 days prior to enrollment or is scheduled to

hemorrhagic diathesis, and cervical C1/C2 arthritis.
21. The participant has had lung surgery which may interfere with bronchoscopy.
