A Study to Assess the Pharmacokinetics of AZD6793 When Administered Alone and in Combination With Itraconazole in Healthy Participants.

This is a single-group study with a duration of up to 8 weeks (maximum of 53 days) including Screening, Period 1, Period 2, Period 3 and Follow-up.

The study will comprise of:

• A screening period of 27 days
• Three treatment periods: Period 1 (Day -1 to Day 3): Single dose AZD6793 will be administered on Day 1 followed by a 3-day washout period; Period 2 (Day 4 to Day 7): Itraconazole will be administered from Day 4 through Day 7, starting with 2 doses of 200 mg itraconazole given 12 hours apart on Day 4, then 200 mg itraconazole will be given once a day on Day 5 through Day 7. Period 3 (Day 8 to Day 11): On Day 8, participants will be co-administered with AZD6793 and 200 mg itraconazole. Administration of 200 mg itraconazole will continue on Day 9 and Day 10. Participants will be discharged from the clinic on Day 11.
• A Follow-up Visit 10-15 days after the last itraconazole dose in Period 3.

• History of clinically significant chronic or active hematologic disease.
• Diagnosis or history of immunodeficiency or increased susceptibility to severe infection, or a clinically significant infection within 4 weeks of the Screening Visit.
• Any clinically important illness, medical/surgical procedure or trauma within 4 weeks of the first administration of study drug.
• Any laboratory values with deviations at the Screening Visit or on admission to the Clinical Unit. Abnormal values may be repeated at the discretion of the Investigator: Alanine transaminase (ALT) > Upper Limit Normal (ULN), Aspartate Transaminase (AST) > ULN, WBC count < Lower limit normal (LLN), Neutrophils > ULN or < LLN, Haemoglobin < 120 g/L, Bilirubin > ULN, Urinary albumin to creatinine ratio abnormal (≥ 3.4 mg/mmol), eGlomerular filtration rate (eGFR) < 85 mL/min/1.73 m² calculated using the CKD-EPI equation (eGFR will only be assessed at Screening).
• Any clinically important abnormalities in clinical chemistry, haematology, or urinalysis results at the screening.
• Positive or indeterminate QuantiFERON® TB test at the Screening Visit.
• Any positive result on screening for serum hepatitis B surface antigen, hepatitis C antibody, or Human immunodeficiency virus (HIV).
• Participants with a history or presence of vitiligo or significant (in the opinion of the investigator) skin depigmentation for any cause including drugs.
• Any clinically significant abnormal finding in vital signs, at the Screening Visit and/or on admission to the Clinical Unit.
• Any clinically important abnormalities in rhythm, conduction or morphology of the resting electrocardiogram (ECG) and any clinically important abnormalities in the 12 lead ECG.
• Current smokers or those who have smoked or used nicotine products (including e-cigarettes) within the 3 months prior to screening.

• Participants who have previously received AZD6793.
• Vulnerable participants.
• Participant has a positive test result for SARS-CoV-2 via RT-PCR on admission to the Clinical Unit.
• Participant has clinical signs and symptoms consistent with Coronavirus disease 2019 (COVID-19).
