Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Adult male or female patient, aged 18 or above.
  • Patient diagnosed with SARS-CoV-2 infection at Screening by using the sponsor-supplied rapid SARS-CoV-2 diagnostic test or RT-PCR.
  • Patient with conditions meeting all of the following criteria:

    1. Oxygen saturation ≥ 94% on room air.
    2. Not requiring supplemental oxygen.
  • Patient who has onset of one or more of the SARS-CoV-2 infection associated symptoms within 7 days prior to the study drug administration.

Exclusion Criteria:

  • Patient with current serious condition meeting one of the following:

    1. Previously or currently hospitalized or requires hospitalization for treatment of serious SARS-CoV-2 related conditions.

  • Patient who has received or has a plan to receive any of following prohibited medications or treatments:

    1. Drugs with actual or possible antiviral drugs and/or possible anti-SARS-CoV-2 activity including but not limited to nirmatrelvir and ritonavir, molnupiravir, remdesivir, chloroquine, hydroxychloroquine, dexamethasone (or alternative corticosteroids to dexamethasone), and other immunomodulatory agents and human immunodeficiency virus protease inhibitors for therapeutic purpose of SARS-CoV-2 infection prior to study drug administration
    2. Any SARS-CoV-2 human intravenous immunoglobulin, convalescent plasma for the treatment of COVID-19 infection prior to study drug administration
    3. Any approved monoclonal antibody (sotrovimab, casirivimab and imdevimab, bamlanivimab and etesevimab, etc), any other investigational device or medical product including but not limited to any monoclonal antibody(tocilizumab, sarilumab, etc.), fusion proteins or biologics for the treatment of COVID-19 infection prior to the first study drug administration.

    5. Study Description

    Brief Summary
    This is a Phase 3 study to assess the efficacy about therapeutic effect of inhaled CT-P63 and CT-P66 combination therapy to symptomatic patiemts with COVID-19 and overall safety.
    Detailed Description
    CT-P63 and CT-P66 are monoclonal antibodies targeted against SARS-CoV-2 spike receptor binding domain as a treatment for COVID-19 infection. CT-P63 and CT-P66 are currently being developed by the Sponsor as a potential treatment for COVID-19 infection. In this study, efficacy, safety, and virology of inhaled CT-P63 and CT-P66 will be evaluated in symptomatic patients with COVID-19 Infection.
