A Study Exploring the Use of Challenge Agents in Healthy Volunteers - Intervention Specific Appendix

Inclusion criteria

• healthy on the basis of physical examination, medical history, and vital signs, and 12-lead electrocardiogram (ECG) performed at screening. Any abnormalities, must be consistent with the underlying illness in the study population and this determination must be recorded in the participant's source documents and initialed by the investigator
• healthy on the basis of clinical laboratory tests performed at screening. If the results of the serum chemistry panel, hematology, or urinalysis are outside the normal reference ranges, the participant may be included only if the investigator judges the abnormalities or deviations from normal to be not clinically significant or to be appropriate and reasonable for the population under study. This determination must be recorded in the participant's source documents and initialed by the investigator
• must be a non-smoker (not smoked for at least 6 months prior to screening) and has not used nicotine-containing products (example, nicotine patch) for 3 months prior to screening
• A woman must be: a) not of childbearing potential; b) Of childbearing potential and practicing a highly effective method of contraception (failure rate of less than (<1) percent (%) per year when used consistently and correctly) and agrees to remain on a highly effective method while receiving study intervention and until the end of the intervention cohort. The investigator should evaluate the potential for contraceptive method failure (example, noncompliance, recently initiated) in relationship to the first dose of study intervention
• A woman of childbearing potential must have a negative highly sensitive serum (beta-human chorionic gonadotropin [beta-hCG]) at screening and a negative urine pregnancy test prior to study intervention administration on Day -4
