Brief Summary

The PJS-539 is a multicentre, phase 2, randomized, double-blind, placebo-controlled clinical trial to evaluate the effect of PJS-539 in the viral load of patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Detailed Description

COVID-19, a disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) became a pandemic in March 2020. Clinically, the coronavirus disease 2019 (COVID-19) ranges from asymptomatic disease in some to severe forms. However, until now, only the use of corticosteroids in selected patients has been shown to improve clinical outcomes in patients with COVID-19.

PJS-539 has been demonstrated to inhibit viral uptake and replication of SARS-CoV-2.

The objective of this Phase II trial is to assess the effect of PJS-539 in the viral load of patients with mild to moderate COVID-19 symptoms.

Primary Outcome Measures
NameTimeMethod
Decay rate of the SARS-CoV-2 viral load.At day 10

Decay rate of the SARS-CoV-2 viral load logarithmic curve obtained via nasopharyngeal swab between the baseline and the fifth and tenth days after randomization.

Secondary Outcome Measures
NameTimeMethod
Hospital admissionDay 28

Need for hospital admission.

Need for invasive mechanical ventilationDay 28

Intubation and initiation of mechanical ventilation for any given reason

Time to symptoms resolutionDay 10

Time from randomization to symptoms resolution

Ordinal clinical scale of symptomsDay 14

Evaluation of the clinical scale of symptoms, which ranges from 1 to 7 as follows: 1. not hospitalized, without limitation of daily activities; 2. not hospitalized, with limitation of daily activities; 3. hospitalized, without the need for supplemental oxygen; 4. hospitalized, requiring supplemental oxygen; 5 hospitalized, requiring high-flow nasal oxygen therapy, non-invasive mechanical ventilation, or both; 6. hospitalized, requiring blood oxygenation through a membrane system, invasive mechanical ventilation, or both; 7. Death.

Adverse eventsUp to 28 days

Grade 1, 2, 3 and 4 adverse events, which were not present at the patient's entrance, defined by the Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events

BleedingUp to 28 days

Defines as:

Major: Defined as clinical bleeding associated with any of the following: fatal outcome, critical site involvement (intracranial, intraspinal, intraocular, pericardial, intra-articular, intramuscular with compartmental or retroperitoneal syndrome), or clinical bleeding with a drop in hemoglobin concentration ≥2g/dL, or need for transfusion of ≥2 units of packed red blood cells or whole blood. All intracerebral (or intraparenchymal) bleeds are included in the primary analysis as hemorrhagic stroke.

Clinically relevant non-major: Defined as clinical bleeding that does not present major bleeding criteria, but requires medical intervention, unscheduled contact (in person or by telephone) with a doctor, temporary interruption of the study drug, pain or impairment of daily activities.

Minor: Defined as clinical bleeding that does not meet criteria for clinically relevant major or non-major bleeding.
