Brief Summary:
This is a first in human clinical study. Part 1 of the clinical study will assess the safety and tolerability, as well as the single dose pharmacokinetics (PK), of inhaled AZD4604 in healthy volunteers (Part 1a, single ascending dose \[SAD\]). The single dose administration will be performed with dry powder inhaler (DPI) formulation of AZD4604. When at least 4 cohorts of the SAD part of the study have been completed, AZD4604 will be administered as a single intravenous (IV) or oral (PO) dose to 2 different cohorts of healthy volunteers (Part 1b). The main purpose is to compare the PK between IV, oral and inhaled administration to further characterize the PK properties of AZD4604 by the various administration routes. The results will be used to improve future study design and interpretation. In Part 2 (Multiple ascending dose \[MAD\]), AZD4604 will be administered at multiple doses (twice daily \[BID\], 7 days) to healthy volunteers. In Part 3, AZD4604 will be administered at multiple doses to patients with mild asthma at dose levels assessed in Part 2. The multiple-dose administration will be performed with DPI-formulated AZD4604.
Detailed Description:
Part 1a of the study will be a randomized, single-blind, placebo-controlled, SAD, sequential group design study. Seven inhaled dose levels of AZD4604 are planned to be investigated in cohorts of 8 healthy volunteers, with 6 healthy volunteers randomly assigned to inhaled AZD4604 and 2 healthy volunteers randomly assigned to inhaled placebo in each cohort.
Part 1a will comprise of:
* A Screening Visit within 28 days before dosing.
* A Treatment Period (Day -1 to Day 7, in the Clinical Unit) with a single inhaled dose of AZD4604 or corresponding placebo on Day 1. Although the anticipated systemic exposure and risk for potential adverse systemic effects are considered to be low for AZD4604, healthy volunteers will remain resident at site for additional 6 days of monitoring.
* A Final Assessment on day of discharge.
In Part 1b, AZD4604 will be administered as a single IV or a PO dose to healthy volunteers in order to compare the PK between IV, PO and inhaled administration. Part 1b will be open-label and consist of 2 dose cohorts, IV and PO, with 6 healthy volunteers in each.
Part 1b will comprise of:
* A washout period of at least 2 weeks for the healthy volunteers who received inhaled dosing in Part 1a will occur before IV or PO dosing in Part 1b. All healthy volunteers will have a Screening Visit within 28 days of dosing.
* A Treatment Period (Day -1 to Day 3, in the Clinical Unit) with a single IV or PO dose of AZD4604 on Day 1.
* A Follow-up Visit within 6 ± 1 day after dosing.
Part 2 of the study will be a randomized, single-blind, placebo-controlled, MAD, sequential group design. This part of the study will be conducted in up to 32 healthy volunteers.
Part 2 will comprise of:
* A Screening Visit within 28 days before first dosing.
* A Treatment Period (Day -1 to Day 12 in the Clinical Unit) with twice daily (BID) inhaled doses of AZD4604 or placebo on Day 1 to Day 6 (12-hour \[+/- 30 minutes\] intervals between doses), and a single inhaled dose on Day 7. The healthy volunteers will remain resident at site for additional 6 days of monitoring, which is predicted to allow sufficient time for near complete washout (estimated time for \> 97% of the dose to have been eliminated) of any target engagement from the lungs. Healthy volunteers will remain in the Clinical Unit for the duration of the treatment period and will be discharged on Day 13, 6 days after administration of the last dose.
* A Final Assessment on day of discharge.
Part 3 of the study will be a randomized, single-blind, placebo-controlled, multiple-dose, PK and pharmacodynamic (PD) study part, with daily non-residential visits during the Treatment Period. This part of the study will be conducted in at least 45 patients with mild asthma (16 patients in Cohorts 1 and 2 and at least 29 patients in the Proof of Mechanism \[PoM\] Cohort).
Part 3 will comprise of:
* A Screening Visit within 42 days before first dosing.
* A Treatment Period (Day -3 to Day 15 as daily non-residential visits) with BID inhaled doses of AZD4604 or placebo on Day 1 to Day 9 (12-hour intervals between doses), and a single inhaled dose on Day 10. Dosing will take place at the clinical site and patients will need to visit the site twice daily on Day 1 to Day 9. The anticipated systemic exposure and risk for potential adverse systemic effects are considered to be low for AZD4604, therefore, patients will not be required to be resident at site during the Treatment Period.
* A Final Assessment (Day 16) on the last day of the Treatment Period.
