Arm Description

Each day participants will receive a single 200 mg dose of upamostat along with a single matching placebo, for a total of 14 days.

Each day participants will receive two 200 mg doses of upamostat, for a total of 14 days.

Each day participants will receive two matching placebos, for a total of 14 days.

Based on dose selected from Part A, each day participants will receive EITHER a single 200 mg dose of upamostat OR two 200 mg doses of upamostat, for a total of 14 days.

Based on dose selected from Part A, each day participants will receive EITHER a single matching placebo OR two matching placebos, for a total of 14 days.

Outcomes

Primary Outcome Measures

Part A - Determination of the safety and tolerability of two dose levels and selection of an upamostat dose for part B
Safety and tolerability will be determined based on the relative incidence and severity (CTCAE v 5.0 criteria) of adverse events, both clinical and laboratory (SOC=investigations) in each active treatment group as compared to placebo. In addition, toxicities (i.e., adverse events considered at lease possible related to study medication) resulting in dose reductions or discontinuation of therapy will be tabulated and compared among treatment groups.
Part B - Comparison between upamostat and placebo in time to sustained recovery from symptomatic illness.
Sustained recovery: recovery maintained for at least 14 or 28 days or through EOS, whichever comes first (assessed in part A and a decision reached as to which period to use for definition of sustained recovery in part B). A patient will be considered to have recovered after meeting the following criteria: 1) is afebrile for at least 48 hours without use of antipyretics; 2) all symptoms have resolved or returned to pre- illness levels, except for: a. fatigue, anosmia, ageusia or dysgeusia, which may be persistent at level similar to that during the acute illness; b. chest pain, cough or dyspnea which if persistent must be at least one grade lower than at the start of treatment and no worse than grade 1 (mild).

Secondary Outcome Measures

Part B - Hospitalization or death from any cause by end of study
Hospitalization or death from any cause within 8 weeks after the first dose of study medication
Part A and at Interim Analysis in Part B - assessment of risk of hospitilization or death
Assessment of risk of hospitilization or death as a function of the presence, number and severity of concerning conditions will be undertaken. This information may be used to develop a definition of very high risk for calculation of the incidence of hospitilization or death in the high risk/very high risk population in part B
Part B - Proportion of patients who are PCR-negative at various time points during the study.
Proportion of patients who are PCR-negative at days 8, 15, 29 and 57 from the start of treatment (landmark analyses)
Part B - Time to resolution of individual disease-related symptoms present at baseline
Time to resolution of individual disease-related symptoms present at baseline
Part B - Development of new disease-related symptoms on study
Development of new disease-related symptoms on study will be captured using the same questionnaire as is being used to capture resolution of symptoms.
Part B - Development of pneumonia on study
Incidence of pneumonia during study among patients without baseline pneumonia
Part B - Changes in laboratory markers of disease severity
Changes in oxygen saturation from baseline to time points at which these are measured on study
Part B - Changes in laboratory markers of disease severity
Changes in CRP from baseline to time points at which these are measured on study
Part B - Changes in laboratory markers of disease severity
Changes in lymphocyte count from baseline to time points at which these are measured on study
Part B - Changes in laboratory markers of disease severity
Changes in cardiac troponin from baseline to time points at which these are measured on study
Part B - Changes in laboratory markers of disease severity
Changes in D-dimer levels from baseline to time points at which these are measured on study

5. Study Description

Brief Summary
A 2-part, multicenter, Phase 2/3, randomized, double-blind, placebo-controlled, parallel group study to evaluate the safety and efficacy of upamostat in adult patients with COVID-19 disease who do not require inpatient care.
Detailed Description
Patients will be seen in a medical facility (ER or COVID-19 clinic) for initial evaluation. Consenting, diagnostically-confirmed COVID-19 patients not in need of hospitalization per investigator assessment and who meet all other inclusion and exclusion criteria will be randomized to treatment and provided with medication and home monitoring devices, and instructed in drug administration and use of the devices. They will take medication daily for two weeks, complete a smartphone-based questionnaire, provide additional monitoring information via devices provided periodically over an 8-week period. Patients will be seen at home by a study nurse or return to the clinic after 2, 4 and 8 weeks on study ("follow up" visits); additional televisits will also be conducted. At the follow up visits nasal swab specimens for COVID-19 PCR and blood specimens for safety labs and disease markers will be collected. In part A of the study, patients will be randomized 1:1:1 to one of two doses of upamostat or placebo. Based on safety results of part A, a dose for part B will be selected, and patients will be randomized 3:2 to active vs placebo.
