Multicenter Double Blind, Parallel-group Phase 2/3 Trial, to Study Raloxifene in Adult COVID-19 Patients.

Phase 3CompletedNCT05172050

Dompé Farmaceutici S.p.A61 enrolled

Overview

The objective of the study is to evaluate the efficacy and safety of two different doses of raloxifene orally administered compared to placebo in patients with early diagnosis of paucisymptomatic COVID-19. Primary objectives: * Evaluation of the effectiveness of therapy in reducing the proportion of subjects who still have viruses in the upper airways after 7 days of therapy * Evaluation of the effectiveness of therapy in reducing the proportion of subjects who requires supplemental oxygen therapy and/or mechanical ventilation within 14 days of starting therapy Secondary objectives: * Evaluation of the effectiveness of therapy in reducing the proportion of subjects who still have viruses in the upper airways after 14 and 28 days of therapy * Evaluation of the effectiveness of therapy in reducing the proportion of subject patients who requires supplemental oxygen therapy and/or mechanical ventilation within 7 or 28 days of starting therapy * 7, 14 and 28 days drug safety and tolerability profile * Assessment of body temperature, blood and biochemical parameters between T0 and T28

The study is a phase 2/3, multicenter, adaptive, randomized, placebo-controlled, double blind, parallel-group study to evaluate efficacy and safety of two doses of raloxifene in adult paucisymptomatic COVID-19 patients.

Women of childbearing potential and fertile men who does not agree to use at least one primary form of contraception for the duration of the study.

Outcomes

Primary Outcomes

Number of Participants With Undetectable SARS-CoV-2 at PCR at Day 7 After Randomization in the FAS

Number of participants who, after an approved molecular test (PCR), were not detected as SARS-CoV2 positive. Based on Approved molecular test (PCR) result at day 7, the responses were considered as "detectable" if PCR result was "Positive" otherwise "undetectable" if PCR result was "Negative" .

Time frame: At Day 7

Number of Participants Not Requiring Oxygen Therapy and/or Mechanical Ventilation at Day 14 After Randomization in the FAS

Proportion of participants who does not require supplemental oxygen therapy (NEWS ≤ 2) and/or mechanical ventilation. NEWS is a system for scoring the physiological measurements that are routinely recorded at the patient's bedside. NEWS uses six physiological measurements. An additional two points are added if the patient is receiving oxygen therapy. The total possible score ranges from 0 to 20. If collected NEWS score \> 2 or mechanical ventilation with result "Yes" then the response was considered as "Required". If collected NEWS score ≤ 2 and mechanical ventilation with result "No" then the response was considered as "Not Required" (if both NEWS score and mechanical ventilation were missing, patient was considered as missing).

Time frame: At Day 14

Secondary Outcomes

Number of Participants With Undetectable SARS-CoV-2 at PCR at Days 14 and 28 After Randomization in the FAS

Number of participants with undetectable SARS-CoV-2 at PCR at day 14 after randomization, and at day 28 after randomization. Based on Approved molecular test (PCR) result at days 14 and 28 after randomization, the responses were considered as "detectable" if PCR result was "Positive" otherwise "undetectable" if PCR result was "Negative".

Time frame: At days 14 and 28 after randomization

Number of Participants Not Requiring Oxygen Therapy and/or Mechanical Ventilation at Day 7 an d at Day 28 in the FAS

Proportion of participants who does not require supplemental oxygen therapy (NEWS ≤ 2) and/or mechanical ventilation after randomization;

Time frame: At days 7 and 28

Number of Patients in Each National Early Warning Score (NEWS) Category in the FAS

Proportion of patients in each National Early Warning Score (NEWS) category after randomization. NEWS is a system for scoring the physiological measurements that are routinely recorded at the patient's bedside. NEWS uses six physiological measurements: respiratory rate; oxygen saturation; temperature; systolic blood pressure; heart rate and level of consciousness. Each scores 0-3 and individual scores are added together for an overall score. An additional two points are added if the patient is receiving oxygen therapy. The total possible score ranges from 0 to 20. The higher the score, the worse the outcome.

Time frame: At days 7, 14, 28

Mean Value of National Early Warning Score (NEWS) Category in the FAS

Mean value of National Early Warning Score (NEWS) category after randomization. NEWS is a system for scoring the physiological measurements that are routinely recorded at the patient's bedside. The total possible score ranges from 0 to 20. The higher the score the greater the clinical risk. Higher scores indicate the need for escalation, medical review and possible clinical intervention and more intensive monitoring

Time frame: At days 7, 14, 28 after randomization

Number of Hospitalized Participants Who at the Beginning of the Study Were at Domicile Isolation After Randomization in the FAS

Proportion of hospitalized participants at Day 7, Day 14 and Day 28 after randomization among subjects who at the beginning of the study were at domicile isolation.

Time frame: At days 7, 14, 28

Number of Participants Admitted to Intensive Care After Randomization in the FAS

Proportion of participants admitted to intensive care. Intensive care is a special medical treatment in which a patient who is dangerously ill is kept under constant observation, typically in a dedicated department of a hospital.

Time frame: At days 7,14 ,28

Number of Survivors in the FAS

Proportion of survivors after randomization. There were no events (i.e. deaths) in any treatment groups and thus the median overall survival could not be estimated. Overall survival was analysed according to the Kaplan-Meier method. Time to event curves were compared (i.e. comparisons of each active treatment group versus placebo) using log-rank test and estimates of hazard ratio were obtained using Cox proportional hazards model.

Time frame: At days 7, 14, 28

Quality of Life Questionnaire (EQ-5D-5L) at 3 Months After Randomization - EQ-5D Descriptive System

The EQ-5D-5L consists of: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The EQ-5D-5L system comprises 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the 5 dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the 5 dimensions can be combined into a 5-digit number describing the patient's health state. In the EQ VAS - quantitative measure of health outcome - the patient records a self-rates health on a vertical visual analogue scale (numbered from 0 to 100) which goes from 'Best imaginable health state' (100) to 'Worst imaginable health state' (0).
