    2. Participants are mild or moderate COVID-19 patients.
    3. Participants have one or more mild or moderate COVID 19-related symptoms as defined by the FDA (see the Diagnosis and Main Criteria for Inclusion) with the onset of symptoms ≤ 3 days prior to the randomization.
  • The expansion phase:

    1. Participants are ≥18 years of age at the time of randomization.
    2. Participants are mild or moderate COVID-19 patients.
    3. Participants have one or more mild or moderate COVID 19-related symptoms as defined by the FDA (see the Diagnosis and Main Criteria for Inclusion) with the onset of symptoms ≤ 5 days prior to the randomization.

Exclusion criteria

Exclusion Criteria:

  • Prior or ongoing medical conditions, medical history, physical findings, or laboratory abnormality that, in the PI's (or delegate's) opinion, could adversely affect the safety of the participant or that might interfere with the conduct of the study.

Interventions

  • DrugHH-120

    Participants randomized to active treatment in escalation phase will receive HH-120 administered via inhalation for 5 consecutive days (Day 1 to Day 5). Planned dose levels to be used for the escalation phase of the study are 50 (BID), 50 (TID), and 100 (BID) mg. The expansion phase will begin once the recommended dose for expansion phase determined, based on safety and preliminary efficacy data from the escalation phase.

  • Drugplacebo

    Participants randomized to placebo group in escalation and expansion phase will receive placebo administered via inhalation for 5 consecutive days (Day 1 to Day 5).

What researchers measure

Primary outcomes

  1. Safety and Tolerability: Incidence, frequency, severity, and duration of treatment-emergent adverse events (TEAEs), treatment-related adverse events (TRAE) and serious adverse events (SAEs), etc.

    Time frame: From Baseline to Day 12

Secondary outcomes

  1. Proportion of participants that achieve SARS-CoV-2 clearance (defined as negative qRT-PCR tests taken on two consecutive days), with the time of clearance being the time of the first negative test.

    Time frame: From Baseline to Day 12

  2. Median time to achieve SARS-CoV-2 clearance (defined as negative qRT-PCR tests taken on two consecutive days), with the time of clearance being the time of the first negative test.

    Time frame: From Baseline to Day 12

  3. Median time to sustained clinical recovery.

    Time frame: From Baseline to Day 12
