A Study to Investigate the Relative Bioavailability of AZD8630 Following a Device and Formulation Transition in Healthy Participants.

Exclusion Criteria

• •History or presence of gastrointestinal, hepatic, or renal disease or any other condition known to interfere with absorption, distribution, metabolism, or excretion of drugs.
• •Any clinically important illness, medical/surgical procedure, or trauma within 4 weeks of the first administration of study intervention.
• •History of any upper or lower respiratory tract infection in the 14 days before screening or during the Screening Period.
• •Clinically significant history of atopy or allergy to common allergens including house dust mite and pollens, or a history of childhood asthma, as judged by the investigator.
• •Medical history of or treatment for hepatitis B or hepatitis C.
• •Other latent or chronic infections (e.g., recurrent sinusitis, genital or ocular herpes, or urinary tract infections) or at risk of infection (major surgery, major trauma, or significant infection) within 90 days of screening, or history of skin abscesses withing 90 days of screening.
• •History of cancer within the last 10 years (20 years for breast cancer) except for basal and squamous cell carcinoma of the skin or in situ carcinoma of the cervix treated and considered cured. Any history of lymphoma is not allowed.
• •Have received live, live attenuated or messenger ribonucleic acid vaccine in the 4 weeks prior to Screening Visit.
• •History of or ongoing acquired or inherited immunodeficiency disorders including but not limited to HIV, common variable immunodeficiency or taking immune replacement therapy.
• •A helminth parasitic infection diagnosed within 24 weeks of Visit 1 that has not been treated or has not responded to standard of care therapy.
• •Any laboratory values with the following deviations at the Screening Visit or on admission to the Clinical Unit.
• •Any clinically important abnormalities in clinical chemistry or hematology results at screening and/or admission to the Clinical Unit, as judged by the investigator.
• •Abnormal vital signs, after 5 minutes supine rest, at screening and/or admission to the Clinical Unit.
• •Any clinically important abnormalities in rhythm, conduction, or morphology of the resting 12-lead ECG, at screening and/or admission to the Clinical Unit, as judged by the investigator that may interfere with the interpretation of QTc interval changes, a prolonged PR interval and abnormal ST wave morphology.
• •Current smokers or those who have smoked or used nicotine products or inhalational cannabis/marijuana products (including e-cigarettes) within the previous 6 months prior to screening or has smoking history of \> 10 pack years. Known or suspected history of alcohol.
• •Known or suspected history of alcohol or drug abuse (including cannabis/marijuana products) or excessive intake of alcohol as judged by the investigator. The use of oral cannabis is permitted.
• •Positive screen for drugs of abuse (including any cannabis/marijuana products), or alcohol or cotinine (nicotine) at screening or on admission to the Clinical Unit.
• •History of severe allergy/hypersensitivity or ongoing clinically important allergy/hypersensitivity, as judged by the investigator.
• •History of hypersensitivity or anaphylaxis to any components of AZD8630 formulation.
• •History of documented immune complex disease (Type III hypersensitivity reactions) to mAb administration.
• •Receipt of immunoglobulin or blood products within 4 weeks prior to Screening Visit.
• •Excessive intake of caffeine-containing drinks or food (eg, coffee, tea, chocolate) defined as the regular consumption of more than 500 mg of caffeine per day (eg, \> 5 cups of coffee \[one cup \~100 mg caffeine\]; one cup of tea \~30 mg caffeine) or would likely be unable to refrain from the use of caffeine-containing beverages during confinement at the investigational site.
• •Use of drugs with enzyme inducing properties such as St John's Wort within 3 weeks prior to the first administration of study intervention.
• •Plasma donation within one month of the Screening Visit or any blood donation/blood loss \> 500 mL during the 3 months prior to the Screening Visit.
• •Participants who have previously received AZD8630.
• •Participants who have medical dietary restrictions or dietary restrictions for which the site are unable to cater.
• •Has received another new chemical entity (defined as a compound which has not been approved for marketing) within 30 days of the first administration of study intervention in this study or within 5 half-lives of the medication, whichever is the longest.
• •Pregnancy or intention to become pregnant during the study, breastfeeding, or unwillingness to use a highly effective method of contraception throughout the study in female participants of childbearing potential or lactating woman.
• •Judgment by the investigator that the participant should not participate in the study if they have any ongoing or recent (i.e., during the Screening Period) minor medical complaints that may interfere with the interpretation of study data or are considered unlikely to comply with study procedures, restrictions, and requirements.
• •Vulnerable participants, e.g., kept in detention, protected adults under guardianship
