Chloroquine Phosphate Prophylactic Use in Health Personnel Exposed to COVID-19 Patients
- Registration Number
- NCT04443270
- Lead Sponsor
- CMN "20 de Noviembre"
- Brief Summary
The primary objective of this study is to evaluate the efficacy and security of chloroquine phosphate prophylactic use for reducing the risk of infection by severe acute respiratory syndrome coronavirus-2 in Health Care Workers exposed to COVID-19 patients.
- Detailed Description
Health Care Workers as first line of hospital care, are at high risk of infection by severe acute respiratory syndrome coronavirus-2 due for the exposure to COVID-19 patients. The pharmacological treatment with chloroquine phosphate has emerged as one of the main therapeutic approaches for COVID-19 patients. However, some studies have described and hypothesized that the use of prophylactic chloroquine phosphate could provide some protection against COVID-19 infection reducing the chances of contagion in Health Care personnel during the development of the pandemic. A controlled clinical trial will be conducted in a tertiary hospital in Mexico City, Mexico. Participants will be divide in two groups; 1) intervention: who will receive chloroquine phosphate (300 mg/day during the first 30 days and 150mg/day during the last 30 days) and 2) control, both with a follow up for 60 days.

Group Intervention Description Chloroquine phosphate prophylactic group Chloroquine phosphate Drug: Chloroquine phosphate Dosage form, frequency and duration: 300 mg per day during initial 30 days and 150 mg per day during the next 30 days.
- Primary Outcome Measures
Name Time Method Negative Polymerase Chain Reaction assay at day 0 Day 0 Prior to the participation of each health worker, a pharyngeal exudate sample will be taken with a swab. RNA will be obtained by applying severe acute respiratory syndrome coronavirus-2 real time polymerase chain reaction kit, using specific oligonucleotides in polymerase chain reaction.
Polymerase Chain Reaction assay at day 60 Day 60 A pharyngeal exudate sample will be taken with a swab. RNA will be obtained by applying severe acute respiratory syndrome coronavirus-2 real time polymerase chain reaction kit, using specific oligonucleotides in polymerase chain reaction.
- Secondary Outcome Measures
Name Time Method Clinical improvement related to COVID-19 From 30-day to 60-day follow-up Ordinal Scale for Clinical Improvement according the "World Health Organization R\&D Blueprint novel Coronavirus COVID-19 Therapeutic Trial Synopsis" will apply at baseline and 30-day follow-up as follows:
No clinical or virological evidence of infection = 0 No limitation of activities = 1 Limitation of activities = 2 Hospitalized, no oxygen therapy = 3 Oxygen by mask or nasal prongs = 4 Non-invasive ventilation or high-flow oxygen = 5 Intubation and mechanical ventilation - Score = 6 Ventilation + additional organ support-pressors, renal replacement therapy, extracorporeal membrane oxygenation = 7 Death = 88Heart rhythm negative adverse event related to the Chloroquine Phosphate Prophylactic Use Baseline (day 0) and 30-day follow up An EKG will be performed to measure QT interval at baseline and 30-day follow-up.
The EKG follows the standards and guidelines established by the Centro Médico Nacional "20 de Noviembre."Heart rhythm negative adverse event related to the Chloroquine Phosphate Prophylactic From 30-day to 60-day follow-up An EKG will be performed to measure QT interval at 60-day follow-up.
The EKG follows the standards and guidelines established by the Centro Médico Nacional "20 de Noviembre."COVID-19 symptomatic onset rate From baseline (day 0) to 60-day follow up According to the National Committee for Epidemiological Surveillance (CONAVE) in Mexico, COVID-19 symptomatic onset rate defined as the presence of cough, fever or headache during the last 7 days, accompanied at least one of the following symptoms: dyspnea, arthralgia, myalgia, odynophagia / pharyngeal burning, rhinorrhea, conjunctivitis or chest pain.
