Phase 2
Completed
Conditions
COVID-19
Interventions
Registration Number
NCT04313023
Lead Sponsor
Pulmotect, Inc.
Brief Summary

Subjects who have documented exposure to SARS-CoV-2 (COVID-19) will receive 4 doses of PUL-042 Inhalation Solution or 4 doses of a placebo solution by inhalation over 10 days. Subjects will be followed for the incidence and severity of COVID-19 over 28 days. Subjects will be tested for infection with SARS-CoV-2 at the beginning, middle and end of the study.

Inclusion Criteria
  1. Subjects must have recent exposure to SARS-CoV-2 (such as repeated or extensive exposure to an infected individual(s) or cohabiting with a SARS-CoV-2 positive individual).
  2. Subjects must be 50 years or older if the exposure is due to cohabitation.
  3. Subjects must be free of clinical signs or symptoms of a potential COVID-19 diagnosis (Ordinal Scale of Clinical Improvement score of 0) with a SARS-CoV-2 infection symptom score (fever, cough, shortness of breath, and fatigue) of 0 in each category.
  4. Spirometry (forced expiratory volume in one second FEV1 and forced vital capacity [FVC]) ≥70% of predicted value.
  5. If female, the subject must be surgically sterile or ≥ 1 year postmenopausal. If of child-bearing potential (including being < 1years postmenopausal) and, if participating in sexual activity that may lead to pregnancy, the subject agrees to use an effective dual method of birth control (acceptable methods include intrauterine device, spermicide, barrier, male partner surgical sterilization, and hormonal contraception) during the study and through 30 days after completion of the study.
  6. If female, must not be pregnant, plan to become pregnant, or nurse a child during the study and through 30 days after completion of the study. A pregnancy test must be negative at the Screening Visit, prior to dosing on Day 1.
  7. If male, must be surgically sterile or, if not surgically sterile and if participating in sexual activities that may lead to pregnancy, be willing to practice two effective methods of birth control (acceptable methods include barrier, spermicide, or female partner surgical sterilization) during the study and through 30 days after completion of the study.
  8. Ability to understand and give informed consent.
Exclusion Criteria
  1. Previous infection with SARS-CoV-2.
  2. Receipt of any vaccine for the prevention of COVID-19 (single or multiple doses).
  3. A SARS-CoV-2 infection symptom score greater than 0 in any of the 4 catergories (fever, cough, shortness of breath or fatigue) at the time of screening (Ordinal Scale for Clinical Improvement score of 0).
  4. Known history of chronic pulmonary disease (e.g., asthma [including atopic asthma, exercise-induced asthma, or asthma triggered by respiratory infection], chronic pulmonary disease, pulmonary fibrosis, COPD), pulmonary hypertension, or heart failure.
  5. Any condition which, in the opinion of the Principal Investigator, would prevent full participation

Primary Outcome Measures
NameTimeMethod
Severity of COVID-19: Evaluation of the Severity of COVID-19 as Measured by the Maximum Difference From the Baseline Value in the OSCI Within 28 Days From the Start of Experimental Therapy.28 days

To determine the efficacy of PUL-042 Inhalation Solution in the prevention of viral infection with SARS-CoV-2 and progression to COVID-19 in subjects: 1) who have repeated exposure to individuals with SARS-CoV-2 infection and, 2) are asymptomatic at enrollment.

The primary endpoint is the severity of COVID-19 as measured by the maximum difference from the baseline value in the Ordinal Scale for Symptom Improvement (OSCI) within 28 days from the start of experimental therapy.

The OSCI to be used in this study is derived from a draft scale proposed by the World Health Organization for clinical improvement as presented below. The minimum score is 0, maximum is 8. Higher values represent a worse outcome.

OSCI Scale:

0 (no evidence of infection), 1 (infected, no limitation of activities), 2 (limitation of activities), 3 (hospitalized), 4 (hospitalized \& requiring oxygen), 5 (requiring high flow oxygen), 6 (requiring mechanical ventilation), 7

Secondary Outcome Measures
NameTimeMethod
Percentage of SARS-CoV-2 Infections Through Day 1514 days

Positive test for SARS-CoV-2 infection 14 days from the start of experimental therapy in subjects who test negative for SARS-CoV-2 at the pre-treatment visit.

Number of Participants With ICU Admission28 days

The requirement for ICU admission within 28 days from the start of experimental therapy.
