Anakinra Rescue Treatment for Moderate Asthma Attacks (ARTMA)

Phase 1Not Yet RecruitingNCT07600190

University of North Carolina, Chapel Hill60 enrolled

Overview

In this single center, interventional pilot study, 40 participants at high risk for future exacerbation will be randomized to anakinra (v. placebo control) treatment for home administration as part of an asthma action plan (AAP) and monitored through their first moderate asthma exacerbation, triggering treatment dosing over a 26 week period. Key feasibility questions will be assessed in this pilot study to inform trial design and sample size selection for a future multi-site phase II clinical trial testing anakinra as a rescue treatment for moderate asthma exacerbations.

This pilot study will incorporate early intervention with the IL-1 receptor antagonist (IL-1RA), anakinra, as part of a home-based asthma action plan (AAP) at the start of a moderate exacerbation with the goal of preventing severe exacerbations requiring systemic steroids. The investigators will determine the feasibility of recruitment, enrollment, and retention for a trial that requires self administered injections; adherence to critical protocol operational tasks and rates of moderate exacerbations; and preliminary safety and efficacy of anakinra treatment during a moderate asthma exacerbation, with the goal of these findings supporting the development a hybrid decentralized phase II trial. 40 adults (≥18 years and \< 65 years) with persistent asthma that experienced an exacerbation within the prior 12 months requiring systemic steroid treatment will be enrolled, with the aim to randomize 20 women and 20 men. Up to 100 subjects will be screened to randomize 40 subjects. Patients are to receive anakinra or placebo during a moderate asthma exacerbation (defined by pre-specified criteria). Investigators will monitor symptom scores, lung function measurements, rescue medication use, systemic corticosteroid use, and healthcare utilization during exacerbations. Device training, blood collection, and nasal sample collection will also occur.

Outcomes

Primary Outcomes

Effect of Anakinra on percent change in Peak Expiratory Flow from baseline during moderate asthma exacerbation

Area under the curve (AUC) of percent change in morning peak expiratory flow (PEF) from baseline, over the period of treatment day 1 through 10 days post-treatment day 1, calculated using the trapezoidal method, and comparing Anakinra to placebo treatment.

Time frame: Day 1 of treatment through day 10 after treatment

Study Design Feasibility - Percentage of participants who experience one moderate asthma exacerbation

Percent of randomized participants who experience one moderate asthma exacerbation (as defined by the participant's asthma action plan) during the 6-month study period.

Time frame: The 6-month period from randomization to the end of study visit

Secondary Outcomes

Effect of Anakinra on Asthma Index during moderate asthma exacerbation

Asthma Index is a continuous variable that reflects the magnitude and timing of changes in asthma control. Asthma scores are calculated using objective peak expiratory flow (PEF) and subjective symptom score elements over a 48-hour period. Asthma scores will be calculated over the period of treatment day 1 through 10 days post-treatment day 1 and subtracted from the mean Asthma score from a stable baseline 7-day period to obtain the Asthma Index. The area under the curve (AUC) of the Asthma Index will be calculated over the period of treatment day 1 through 10 days post-treatment day 1. Higher Asthma Index AUC values represent a greater cumulative burden of uncontrolled asthma relative to the individual's stable baseline (i.e., worse asthma control), while lower values represent better-maintained asthma control over the assessment period.
