Abstract

Context. The Covid-19 pandemic is of unprecedented magnitude and has had major social and health consequences. Primary care professionals, mainly general practitioners, ensure the care of most patients with Covid-19. An early-stage treatment administered to patients with risk factors for developing a severe disease could reduce hospitalization and death rates. No treatment is currently validated in this indication. Objectives. To evaluate the safety and efficacy of experimental candidate agents delivered in outpatient settings to reduce the risk of hospitalization or death in at-risk patients with early-stage proven Covid-19 and no indication for hospital admission. Methods. Multicentric, open-label, multi-arm, multi-stage (MAMS) randomized controlled trial with a pilot tolerability and safety phase, and a clinical efficacy phase. Efficacy will be determined by the proportion of participants who have an indication for hospital admission, administration of acute oxygen therapy (because of Covid-19) or who decease between D0 and D14 in the experimental treatment group compared to the control group. Expected results. This trial will assess the tolerance and efficacy of diverse treatments administered at an early stage of Covid-19, in patients with risk factors of developing a severe disease. It will also provide information that can contribute to increase primary care actors' ability to conduct clinical trials at the national level., Contexte.

Abstract

Background: Sexually transmitted infections are a major public health issue, both in France and worldwide. Primary healthcare professionals play a key role in sexual health and prevention, but few take on this subject. Prevention strategies are diverse, thus risk reduction strategies focussing on behavioural changes are still needed.Purpose: We conducted a systematic review to analyse risk reduction interventions focussing on behavioural change in OECD countries in primary healthcare settings to help develop a prevention tool easy to apply in primary care.Methods: We searched for English- or French-language controlled trials in PubMed, Cochrane Library, Scopus, PsycINFO, PsycArticle, PBSC, SocINDEX, Google Scholar, and CAIRN, supplemented with the bibliographies of previous systematic reviews. Thirty controlled, randomized, or nonrandomized trials were included in the systematic review. We did not conduct any meta-analysis due to the diversity of populations, outcomes and study designs.Results: There are efficient interventions in primary healthcare settings for reducing sexual risk behaviours and/or incident STI. Their efficiency seems to grow with the length and intensity of the intervention. Most interventions target only young, high-risk patients, and their long-term impact is uncertain. Most included studies had an overall risk of bias estimated as high or with some concerns.Conclusions: Some tools could be used in primary care, with possible efficiency though results are difficult to generalize, and value should be assessed in daily practice. Future research should also focus on older population given the epidemiological evolutions, but also lower-risk population to target all patients seen in primary care settings.

Abstract

Objectives: To assess the efficacy of several repurposed drugs to prevent hospitalisation or death in patients aged 65 or more with recent symptomatic SARS-CoV-2 infection (COVID-19) and no criteria for hospitalisation.Trial Design: Phase III, multi-arm (5) and multi-stage (MAMS), randomized, open-label controlled superiority trial. Participants will be randomly allocated 1:1:1:1:1 to the following strategies: Arm 1: Control arm Arms 2 to 5: Experimental treatment arms Planned interim analyses will be conducted at regular intervals. Their results will be reviewed by an Independent Data and Safety Monitoring Board. Experimental arms may be terminated for futility, efficacy or toxicity before the end of the trial. New experimental arms may be added if new evidence suggests that other treatments should be tested. A feasibility and acceptability substudy as well as an immunological substudy will be conducted alongside the trial.Participants: Inclusion criteria are: 65-year-old or more; Positive test for SARS-CoV-2 on a nasopharyngeal swab; Symptoms onset within 3 days before diagnosis; No hospitalisation criteria; Signed informed consent; Health insurance. Exclusion criteria are: Inability to make an informed decision to participate (e.g.: dementia, guardianship); Rockwood Clinical Frailty Scale ≥7; Long QT syndrome; QTc interval > 500 ms; Heart rate <50/min; Kalaemia >5.5 mmol/L or <3.5 mmol/L; Ongoing treatment with piperaquine, halofantrine, dasatinib, nilotinib, hydroxyzine, domperidone, citalopram, escitalopram, potent inhibitors or inducers of cytochrome P450 CYP3A4 isoenzyme, repaglinide, azathioprine, 6-mercaptopurine, theophylline, pyrazinamide, warfarin; Known hypersensitivity to any of the trial drugs or to chloroquine and other 4-aminoquinolines, amodiaquine, mefloquine, glafenine, floctafenine, antrafenine, ARB; Hepatic porphyria; Liver failure (Child-Pugh stage ≥B); Stage 4 or 5 chronic kidney disease (GFR <30 mL/min/1.73 m²); Dialysis; Hypersentivity to lactose; Lactase deficiency; Abnormalities in galactose metabolism; Malabsorption syndrome; Glucose-6-phosphate dehydrogenase deficiency; Symptomatic hyperuricemia; Ileus; Colitis; Enterocolitis; Chronic hepatitis B virus disease. The trial is being conducted in France in the Bordeaux, Corse, Dijon, Nancy, Paris and Toulouse areas as well as in the Grand Duchy of Luxembourg. Participants are recruited either at home, nursing homes, general practices, primary care centres or hospital outpatient consultations.Intervention and Comparator: The four experimental treatments planned in protocol version 1.2 (April 8th, 2020) are: (1) Hydroxychloroquine 200 mg, 2 tablets BID on day 0, 2 tablets QD from day 1 to 9; (2) Imatinib 400 mg, 1 tablet QD from day 0 to 9; (3) Favipiravir 200 mg, 12 tablets BID on day 0, 6 tablets BID from day 1 to 9; (4) Telmisartan 20 mg, 1 tablet QD from day 0 to 9. The comparator is a complex of vitamins and trace elements (AZINC Forme et Vitalité®), 1 capsule BID for 10 days, for which there is no reason to believe that they are active on the virus. In protocol version 1.2 (April 8th, 2020): People in the control arm will receive a combination of vitamins and trace elements; people in the experimental arms will receive hydroxychloroquine, or favipiravir, or imatinib, or telmisartan.Main Outcome: The primary outcome is the proportion of participants with an incidence of hospitalisation and/or death between inclusion and day 14 in each arm.Randomisation: Participants are randomized in a 1:1:1:1:1 ratio to each arm using a web-based randomisation tool. Participants not treated with an ARB or ACEI prior to enrolment are randomized to receive the comparator or one of the four experimental drugs. Participants already treated with an ARB or ACEI are randomized to receive the comparator or one of the experimental drugs except telmisartan (i.e.: hydroxychloroquine, imatinib, or favipiravir). Randomisation is stratified on ACEI or ARBs treatment at inclusion and on the type of residence (personal home vs. nursing home).Blinding (masking): This is an open-label trial. Participants, caregivers, investigators and statisticians are not blinded to group assignment.Numbers To Be Randomised (sample Size): A total of 1057 participants will be enrolled if all arms are maintained until the final analysis and no additional arm is added. Three successive futility interim analyses are planned, when the number of participants reaches 30, 60 and 102 in the control arm. Two efficacy analyses (interim n°3 and final) will be performed successively.Trial Status: This describes the Version 1.2 (April 8th, 2020) of the COVERAGE protocol that was approved by the French regulatory authority and ethics committee. The trial was opened for enrolment on April 15th, 2020 in the Nouvelle Aquitaine region (South-West France). Given the current decline of the COVID-19 pandemic in France and its unforeseeable dynamic in the coming months, new trial sites in 5 other French regions and in Luxembourg are currently being opened. A revised version of the protocol was submitted to the regulatory authority and ethics committee on June 15th, 2020. It contains the following amendments: (i) Inclusion criteria: age ≥65 replaced by age ≥60; time since first symptoms <3 days replaced by time since first symptoms <5 days; (ii) Withdrawal of the hydroxychloroquine arm (due to external data); (iii) increase in the number of trial sites.Trial Registration: The trial was registered on Clinical Trials.gov on April 22nd, 2020 (Identifier: NCT04356495): and on EudraCT on April 10th, 2020 (Identifier: 2020-001435-27).Full Protocol: The full protocol is attached as an additional file, accessible from the Trials website (Additional file 1). In the interest of expediting dissemination of this material, the familiar formatting has been eliminated; this Letter serves as a summary of the key elements of the full protocol. The study protocol has been reported in accordance with the Standard Protocol Items: Recommendations for Clinical Interventional Trials (SPIRIT) guidelines (Additional file 2).
