Study Description

Brief Summary:

This is a randomized, single blind, study. Males and females meeting inclusion criteria who have symptoms of mild COVID-19 and in whom a positive PCR result for SARS-CoV-2 is obtained may be enrolled to the study treatment within 72 hours of the positive PCR result. Eligible patients are those considered to be at high risk for COVID-19 disease progression. This includes patients ≥ 65 years of age or with any one or more of certain medical conditions including: cancer, COPD, cardiovascular disease, immunocompromised state resulting from solid organ transplant, obesity, sickle cell disease, history of smoking, and diabetes.

Condition or disease	Intervention/treatment	Phase
COVID-19	Drug: STAT-205	Phase 1

Detailed Description:

Eligible patients will be randomized, 1:2, to either placebo or STAT-205. Randomization will be stratified by site. STAT-205 treatment will include an initial 5-day dosing period (period 1) of 22.5 mg QD, to be followed by a second dosing period (period 2) of 4.5 mg QD to complete 30 days of dosing. Patients randomized to placebo will receive placebo QD. Blood samples for pharmacokinetic analysis and measurement of inflammatory biomarkers will be collected from patients on day 1, day 6, day 15 and day 30. Patients will be seen in the clinic on days 1, 6, 15, and 30. Patients will be contacted via telephone for follow up on day 60 and on. each post treatment day through Day 60. The telephone visit should occur at approximately the same time each day. During the telephone visits, the presence and severity of COVID-19 symptoms that were recorded at Baseline will be queried, and any new symptoms will be recorded. During the daily telephone visits, patients will also be queried for any adverse events.

4. Documentation of positive diagnostic test for SARS-CoV-2 (confirmed by PCR assay or other approved diagnostic test) performed with a sample from nares or saliva, collected within 7 days of the Screening visit.
5. Is symptomatic for COVID-19 for no more than 7 days prior to the Screening visit
6. Has a WHO Clinical Progression Scale (WHOb 2020) score of either '2' or '3' at Screening and Randomization
