NCT05667662

Brief Summary

The goal of this clinical trial is to learn about PUR1900 as an inhaled, antifungal therapeutic for the treatment of allergic bronchopulmonary aspergillosis (ABPA) in patients with asthma. The main questions it aims to answer are:

  1. 1.Is PUR1900 safe and well tolerated in adults with asthma and ABPA?
  2. 2.Is there an effect of daily administration of PUR1900 on potential outcome measures in adults with asthma and ABPA?
  3. 3.Is there fungal resistance to A. fumigatus?

Outcome Measures

Primary Outcomes (6)

  • Incidence of Treatment Emergent Adverse Events (TEAEs)

    Review of TEAEs from time of consent to study completion.

    168 days

  • Safety spirometry assessments

    FEV1 (the volume of air (in liters) exhaled in the first second during forced exhalation after maximal inspiration), FVC (liters), and PEFR (L/min) measurements compared to baseline.

    168 days

  • Vital sign measurements

    Vital signs measurements collected before exposure, during and after treatment and compared to baseline. Vital sign measurements will include respiratory rate (bpm), blood pressure (mmHg), heart rate (bpm), oxygen saturation (by pulse oximetry), and oral or tympanic temperature (°C).

    168 days

  • Physical examinations

    At screening, a complete physical examination will be performed which includes measurement of height (cm), weight (kg) and evaluation of appearance; skin; head and neck; eyes, ears, nose, and throat; chest and lungs; heart; abdomen; neurological system; and extremities.

    168 Days

  • Clinical safety laboratory test results

    Hematology, serum chemistry, or urinalysis test results (normal, abnormal, clinical significance) compared to baseline.

    168 days

  • Cardiac safety monitoring

    Electrocardiogram (ECG) recordings collected before exposure, during and after treatment. Electrocardiogram measurements will include heart rate and PR, RR, QRS, and QT intervals, as well as the QTcF and compared to baseline.

    168 days

Secondary Outcomes (4)

  • Magnitude of effect of daily administration of PUR1900 - Spirometry

    168 days

  • Magnitude of effect of daily administration of PUR1900 - Patient Reported Outcomes (ACQ)

    168 days

  • Magnitude of effect of daily administration of PUR1900 - Patient Reported Outcomes (AQLQ(s) 12+)

    168 days

  • Frequency of asthma exacerbations versus baseline

    168 days

Other Outcomes (1)

  • Fungal resistance to Aspergillus fumigatus

    168 days

Eligibility Criteria

Age18 Years+

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Is a male or female, ≥18 years old at the time of signing the informed consent.
  • BMI of ≥18.0 and \<40.0 kg/m2 at screening.
  • Has a diagnosis of asthma, as per the Global Initiative for Asthma (GINA) 2018 update
  • Has a confirmed diagnosis of ABPA, based on the modified International Society for human and Animal Mycology (ISHAM) ABPA working group 2013 and 2021 criteria including a history of or documentation at screening of serum IgE ≥ 500 IU/mL and A. fumigatus-specific IgE\>0.35KUA/L, or above normal IgE antibody to A. fumigatus, or a positive immediate skin test and at least 2 of the 3 following supportive criteria: eosinophil count \>500 cells/µL; A. fumigatus-specific IgG \>27 mgA/L or presence of precipitating (or above normal immunoglobulin G \[IgG\]) antibody to A. fumigatus; consistent radiographic opacities or bronchiectasis on chest CT.
  • Is currently considered to be in one of the following stages of ABPA: Stage 2 (Response), Stage 4 (Remission), Stage 5a (Treatment-dependent ABPA), or Stage 5b (Glucocorticoid-dependent asthma).
  • At least 1 exacerbation requiring a systemic glucocorticosteroid(s) in the 12 months prior to Screening. For patients on a biologic agent, at least one exacerbation requiring a systemic glucocorticosteroid(s) must have occurred at least 3 months after the initiation of the biologic agent.
  • Has a serum IgE ≥500 IU/mL at screening.
  • Has a documented stable asthma medication regimen during the 28 days prior to the first dose of study drug ; applicable asthma medications can include but are not limited to the following: inhaled short-acting beta agonist (SABA), inhaled long-acting beta agonist (LABA), and leukotriene receptor antagonist (LTRA) use and inhaled and/or oral glucocorticosteroids. SABA use during this period should be mostly within a stable range (e.g., 2 puffs 2 to 4 times a day) and should not exceed 8 puffs a day on 2 out of 3 consecutive days.
  • Can perform a valid, reproducible spirometry test with demonstration of a prebronchodilator FEV1 ≥50% of predicted normal for age, sex, race, and height at a screening visit.
  • Can demonstrate the correct inhalation technique and achieve a minimum inspiratory flow rate of 45 L/min for the use of the delivery device at screening and before dosing on Day 1.
  • Is willing and able to comply with all study procedures and assessments, including scheduled visits, drug dosing plan, study procedures, laboratory tests, and study restrictions.

A subject whose predominating clinical disease burden is related to bronchiectasis (e.g., a subject with 2 or more infective exacerbations of bronchiectasis in the past 12 months or a subject with chronic colonization with Pseudomonas aeruginosa) will be excluded. Refer to Appendix 4 for definition of bronchiectasis exacerbations.
  • Had an occurrence of clinically significant bacterial, viral, or fungal infection that required systemic (oral or intravenous) antibiotics, antivirals, or antifungals within the 28 days before screening. Topical treatments, other than antifungals, are allowed.
  • Had an occurrence of asthma or ABPA exacerbations within the 28 days before screening.
  • Has the presence of hoarseness or oropharyngeal candidiasis at screening.

  • Has a history of any clinically significant drug or alcohol abuse in the past 6 months before screening, as judged by the Investigator.
  • Has current inhaled tobacco/nicotine or inhaled marijuana use or history of smoking or vaping including tobacco or marijuana within the last 6 months before screening.
  • Has a history of any clinically significant drug or alcohol abuse in the past 6 months before screening, as judged by the Investigator.
