Description of intervention(s) / exposure
Phase I, open-label study involving 48 patients
- To evaluate the safety of two escalating doses of PAX-1 in patients with moderate COVID-19.
- To assess the efficacy and pharmacodynamic effects of PAX-1 in patients with moderate COVID-19.

- Investigational Product: PAX-1 (tablet, 2.5mg/tablet)
- Route of administration: Oral
- Frequency of administration: Twice (for 5mg/day dose) or three (for 7.5mg/day dose) times daily for ten days
- Cohorts:
1. 5 mg PAX-1 + Standard of care (SOC)
2. 7.5 mg PAX-1 + Standard of care (SOC)

- The first 20 enrolled patients will be treated with the lowest dose of PAX-1 (5 mg) + SOC.
- When all 20 patients have completed treatment, a Data and Safety Monitoring Board (DSMB) will convene to evaluate the safety profile of the dose.
- Enrolment of the 20 patients in the 7.5 mg + SOC cohort will begin if and only when the DSMB considers the safety profile of PAX-1 to be appropriate.
- Patients in all cohorts will be treated with PAX-1 for 10 days or until complete recovery, whichever occurs first.
- Patients in all cohorts will be treated concomitantly with SOC as per local practice and regulatory guidelines.
- All patients will ingest medications under clinical monitoring.

Other design features
The first 20 enrolled patients will be treated with the lowest dose of PAX-1 cohort.
When all 20 patients have completed treatment, DSMB will convene to evaluate the safety profile of the dose.
Enrolment of the 20 patients in the escalated dose of PAX-1 cohort will begin if and only when the DSMB considers the safety profile of PAX-1 to be appropriate.

Statistical methods / analysis
Planned number of subjects: A total of 48 patients (at least 40 subjects with a dropout rate of 20% ) are planned to be enrolled.
Given that the primary objective of the study is to investigate the safety of two escalating doses of PAX-1, the sample size of 20 patients in each cohort is based on the probability of occurrence of at least one event with an incidence of 10% in the population sample. With a sample size of 20, the probability of observing at least one event will be 0.88 when the probability of an event is 0.1.

Statistical Analysis Plan (SAP) will be produced between finalization of the CRF and database lock. This will include detailed descriptions of all statistical methodology to be utilized, planned analyses, together with master table and listing shells and outline figures for reporting. The SAP will be approved and signed prior to clean file.
