Brief Summary

This is a randomised, double-blind, placebo-controlled, dose escalation study to evaluate the safety, tolerability, and PK of single and multiple inhaled doses of imatinib inhalation solution (AER-901) in healthy adult volunteers. This study consists of 3 parts and an optional fourth part.

Detailed Description

This is a randomised, double-blind, placebo-controlled, dose escalation study to evaluate the safety, tolerability, and PK of single and multiple inhaled doses of imatinib inhalation solution (AER-901) in healthy adult volunteers. This study consists of 3 parts and an optional fourth part:

• Part A: double-blind, placebo-controlled, single ascending dose (SAD).
• Part B: double-blind, placebo-controlled, multiple ascending dose (MAD).
• Part C (optional): open-label, single-dose, crossover. The decision to proceed with Part C will be made by the Sponsor after reviewing unblinded safety and PK data from Part D of the study.
• Part D: double-blind, placebo-controlled, 5 mg single dose (SD) followed by a twice daily (BID) 5 mg dose (total daily dose of 10 mg) of AER-901 in a propylene glycol formulation vs. placebo.

Oversight for the study will be provided by an SRC composed of the Principal Investigator (PI), the Sponsor's Medical Monitor (MM) and an independent MM. The decision to progress from Cohort A1 to Cohort A2 will be based on safety and tolerability data and not PK data from Cohort A1. However, the decision to progress from Cohort A2 to Cohort A3 will be based on review of safety and tolerability data from Cohort A2 and PK data from Cohort A1 by the SRC. A similar sequence will follow for subsequent progression decisions by the SRC for the cohorts in Part A and Part B of the study.

All parts of the study (A, B, C, and D) will include a 28-day Screening period, a Treatment period, and a Follow-up period. Parts C and D include an additional treatment period and a Washout period between the 2 treatment periods.

Throughout this Study Protocol, timings for post-dose assessments for spirometry, ECG, blood and urine samples for PK analysis are stated in relation to completion of the most recent dose of IP.

Study Groups

AER-901 Solution for Nebulization

The inhalation formulation AER-901 for Part A and Part B (Cohort B1 only) is a sterile, yellow solution composed of imatinib mesylate and sterile water for injection. AER-901 will be supplied in 2 solution strengths (5 mg/mL and 40 mg/mL) for nebulisation.

The AER-901 inhalation formulation for Part D is a sterile yellow solution composed of imatinib mesylate, sterile water for injection and propylene glycol. AER-901 will be supplied in 2 solution strengths (5 mg/mL and 40 mg/mL) and the Pharmacy Manual will provide guidance on preparation for nebulization. Following review of the Part D safety and PK data by the SRC, the SRC will recommend which formulation and dose of AER-901 (sterile water vs propylene glycol) will be used in Parts B (Cohorts B2 and B3) and Part C.

The solution will be filled into a suitable container-closure system and delivered via a nebuliser known as the FOX® MOBILE. The water acts as the medium for nebulisation.

Group Type: EXPERIMENTAL

AER-901 Solution for Nebulization

Intervention Type: DRUG

Part A: participants will be enrolled into 1 of up to 5 sequential cohorts (A1 to A5). Inhaled AER-901 doses of 5, 10, 20, 40, and 80mg are planned.

Part B: participants will be enrolled into 1 of up to 3 cohorts (B1 to B3).

Cohorts B2 and B3 will commence following Part D of the study and following SRC review of safety, tolerability, and PK data. A decision to dose with either a propylene glycol formulation or a sterile water formulation will be made by the SRC at the time of the review of the Part D data.

Part D has a three-part design (Treatment Periods 1 & 2 separated by a Washout period) and will compare placebo to a single-dose of AER-901 (5 mg/mL QD) followed by two doses of AER-901.

Each cohort will consist of 8 participants (6 receiving AER 901 and 2 receiving placebo).

Placebo

A volume-matching placebo (0.45% sterile saline for injection) is to be delivered via the FOX® MOBILE device.

Group Type: PLACEBO_COMPARATOR

Placebo

Intervention Type: DRUG

0.45% sterile saline for injection delivered via the FOX MOBILE device.
