Brief Summary:
This randomized, open-label, prospective, parallel-group controlled clinical study that aims to explore the natural history of COVID-19 illness and the safety of KB109, a novel glycan, plus SSC versus SSC alone and measures of health in outpatients with mild-to-moderate COVID-19.

Condition or disease Intervention/treatment Phase
Mild-to-moderate COVID-19 Other: KB109 + Self Supportive Care (SSC) Other: Self Supportive Care (SSC) Alone Not Applicable

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 400 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Other
Official Title: A Randomized, Open Label, Prospective, Parallel Group Study to Assess the Natural History of COVID-19 and Effects of KB109 in Addition to Supportive Self Care (SSC) Compared to SSC Alone on Measures of Health in Non-hospitalized Patients With Mild-Moderate COVID-19
Actual Study Start Date : July 2, 2020
Estimated Primary Completion Date : October 2020
Estimated Study Completion Date : December 2020

Arm Intervention/treatment
KB109 + Self Supportive Care (SSC) Other: KB109 + Self Supportive Care (SSC)
KB109 is a novel glycan

Self Supportive Care (SSC) Alone Other: Self Supportive Care (SSC) Alone
Self Supportive Care (SSC) Alone

Primary Outcome Measures :
  1. Number of patients experiencing study-product related treatment-emergent adverse events (TEAEs) [ Time Frame: Day 1 to Day 35 ]

Secondary Outcome Measures :
  1. Change from baseline to end of intake in overall composite COVID-19 symptom score [ Time Frame: Day 1 to Day 14 ]
    The composite COVID-19 symptom score is the sum of the 8 cardinal COVID-19 related symptom scores (cough, chills/repeated shaking with chills, muscle pain, fever, headache, anosmia/ageusia, shortness of breath, and sore throat). Each COVID-19 symptom will be recorded by patients on a scale of 0: Absent, 1: Mild: Moderately severe. The overall composite score ranges from 0 (no symptoms) to 24 (very severe)

  2. Time to resolution of fever [ Time Frame: Day 1 to Day 35 ]
    Resolution of fever is defined as from Day 1 until the day at which a patient's daily maximum temperature achieves and remains below 100.4 Degrees Fahrenheit for the rest of the intake period and for the follow-up period without an antipyretic medication.

  3. Proportion of patients with decreased oxygen saturation [ Time Frame: Day 14, Day 35 ]
  4. Effect of COVID-19 symptoms on physical activities [ Time Frame: Day 1 to Day 35 ]
    Effect of COVID-19 symptoms on physical activities rated as: not at all, very little, somewhat, quite a lot, could not do physical activities.

  5. Proportion of patients requiring hospitalization [ Time Frame: Day 1 to Day 35 ]
