About

The study will evaluate the pharmacokinetics (PK) of AZD6793 when administered alone and in combination with itraconazole in healthy adult participants.

Full description

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.

Enrollment: 17 patients
