Phase 1 Study Evaluating Safety and Pharmacokinetics of ASY202 in Adults With Asthma

June 18, 2026 updated by: Aspeya, Inc.

A Phase 1 Randomized, Double-blind, Placebo-controlled, Crossover Clinical Trial to Evaluate the Safety, Tolerability, and Pharmacokinetics of a Single-dose of ASY202 in Adults With Asthma

This is a phase 1 study, randomized, double-blind, placebo-controlled, 2 treatment, 2 period crossover study to evaluate the pharmacokinetics, safety, and tolerability of a single inhaled dose of ASY202 in adults with stable asthma.

Following screening, eligible participants will be enrolled and randomized to one of two treatment sequences. Participants will receive a single inhaled dose of ASY202 and a single inhaled dose of placebo, each administered once during separate study periods.

During each treatment period, subjects will stay in the clinical research unit for safety monitoring and PK assessments, including serial blood sampling, spirometry, vital signs, clinical laboratory tests, and ECGs. Each period will include post dose assessments for up to 24 hours.

Participants will return for their next treatment period after a washout interval to ensure complete clearance of study medication. All subjects will receive both treatments over the course of the study.

A follow-up visit will occur after the last dose to assess ongoing safety and tolerability.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: ASY202, then placebo
ASY202 is a pre-metered drug-device combination product containing DHE dry powder formulation for oral inhalation, delivered via a dry powder inhaler (DPI) device. In Treatment Period 1, participants will receive ASY202, followed by a washout period and subsequent administration of placebo in Treatment Period 2. The placebo consists of an inactive inhalation powder delivered via a matching DPI device.
ASY202 is a pre-metered drug-device combination product containing a dry-powder formulation of dihydroergotamine (DHE) intended for oral inhalation, delivered via a dry powder inhaler (DPI).
Placebo inhalation powder delivered via a dry powder inhaler (DPI) device.
Experimental: Placebo, then ASY202
In Treatment Period 1, participants will receive placebo inhalation powder delivered via a dry powder inhaler (DPI) device, followed by a washout period and subsequent administration of ASY202 in Treatment Period 2.
