• Has adequate venous access.
• Is able to demonstrate correct use of the device using a practice device and follow directions for use.
• Able to follow contraceptive measures as per Protocol.
• Ability and willingness to refrain from undertaking any strenuous exercise (including weightlifting) 48 hours prior to each clinic visit.
• Ability and willingness to refrain from alcohol and/or drug use from Screening (or at least 1 week prior to dosing) (testing at Day -1 to ensure compliance) until EOS (Part 1: until Visit 3/EOS).

You may not qualify if:

• Participant who is pregnant or lactating at Screening or planning to become pregnant (self or partner) at any time from screening to the end of study visit (Part 1: through Visit 3/EOS).
• Participant has a history of significant hypersensitivity or intolerance to lactose and/or epinephrine.
• Participant has a history or clinical manifestation of any metabolic, allergic, dermatological, hepatic, renal, haematological, pulmonary, cardiovascular (including severe pulmonary haemorrhage), gastrointestinal, neurological (including history of migraine requiring specific treatment), respiratory, endocrine, or psychiatric disorder, as determined by the Investigator (or designee) except for fully resolved childhood asthma.
