Project description:ObjectivesTo determine the efficacy of Hydroxychloroquine vs. Hydroxychloroquine + Nitazoxanide in reducing the need for invasive mechanical ventilatory support for patients with COVID-19. Hydroxychloroquine is currently being used in multiple trials with varying doses in an attempt to treat COVID-19. Nitazoxanide has powerful antiviral effects and proven efficacy against a range of viruses including SARS and MERS. Dual therapy by combining appropriate doses of these two medications with diverse activities against COVID-19 is expected to be better than monotherapy with hydroxychloroquine.Trial designThis is a single centre, randomized, controlled, single blinded, 2 arm (ratio 1:1) parallel group trial.Participants86 COVID-19 positive patients that are being treated at the Health Institute of the State of Mexico (ISEM) in Toluca, State of Mexico will be recruited from May 14 to December 31, 2020.Inclusion criteria1)Age older than 18 years.2)Hospitalised COVID-19 PCR test positive patients.3)Within the first 72 hours after performing the PCR test.4)Presence of risk factors for complications (at least one): over 60 years, history of diabetes mellitus, hypertension, and morbid obesity.Exclusion criteria1)Patients with corrected QT interval (QTc) greater than 500ms at hospital admission.2)Patients who have inherent contraindications to each drug.3)Patients who are unable to consent.4)Patients who have previously received chloroquine.5)Patients already intubated. Elimination criteria: 1)Patients whose clinical follow-up is lost or who decide not to continue in the study INTERVENTION AND COMPARATOR: The two management alternatives will be: Control - Hydroxychloroquine 200 mg taken orally every 12 hours for 7 days. Dual therapy - Hydroxychloroquine 400 mg taken orally every 12 hours for two days and then 200 mg taken orally every 12 hours for four days + Nitazoxanide 500 mg orally every 6 hours taken with food, for seven days.Main outcomesPrimary: Mechanical ventilation requirement assessed at one week. Percentage of COVID-19 positive patients who require mechanical ventilation . All patients will be monitored till hospital discharge or death.RandomisationPatients will be randomly allocated using allocation papers and opaque sealed envelopes to either receive the placebo or the dual therapy intervention treatment in a 1:1 ratio until we have recruited the required number of patients for each group.Blinding (masking)Trial participants will be blinded.Numbers to be randomised (sample size)86 participants will be randomized to each group, with 43 in the control group and 43 in the dual therapy group.Trial statusProtocol version: 2, recruitment will begin on May 14 until sample size is reached , with the analysis deadline of December 31st 2020.Trial registrationClinicalTrials.gov Identifier: NCT04341493.

Project description:ObjectivesIn this study, we investigate the effect of hydroxychloroquine on the prevention of Novel Coronavirus Disease (COVID-19) in cancer patients being treated.Trial designThis is a multi-centre, two-arm, parallel-group, triple-blind, phase 2-3 randomised controlled trial.ParticipantsAll patients over the age of 15 from 5 types of cancer are included in the study. Patients with acute lymphoid and myeloid leukemias in the first line treated with curative intent, patients with high-grade non-Hodgkin's lymphoma treated with leukemia protocols and patients with non-metastatic breast and colon cancer in the first line of treatment will enter the study. The exclusion criteria will include known sensitivity to Hydroxychloroquine, weight below 35 kilograms, history of retinopathy, history of any cardiac disease, acute respiratory tract infection in the last 2 months, having COVID-19 in the first two weeks of entering the trial, having Diabetes Mellitus, having an immuno-suppressive disease other than cancer, having chronic pulmonary disease and taking immuno-suppressant drug other than chemotherapeutic agents for current cancer. This study is performed in five academic centres affiliated to Mashhad University of Medical Sciences, Mashhad, Iran.Intervention and comparatorPatients are randomly assigned to two groups; one being given hydroxychloroquine and the other is given placebo. During two months of treatment, the two groups are treated with either hydroxychloroquine (Amin® Pharmaceutical Company, Isfahan, Iran) or placebo (identical in terms of shape, colour, smell) as a single 200 mg tablet every other day. Patients will be monitored for COVID-19 symptoms during the follow-up period. If signs or symptoms occur (fever, cough, shortness of breath), they will be examined and investigated with a high-resolution computed tomography (CT) scan of the lungs, COVID-19 specific IgM, IgG antibody assay and a nucleic acid amplification test (NAT) for the SARS-CoV-2 virus.Main outcomesThe primary end point of this study is to investigate the incidence of COVID-19 in patients being treated for their cancer over a 2-month period.RandomisationRandomisation will be performed using randomly permuted blocks. By using an online website (www.randomization.com) the randomization sequence will be produced by quadruple blocks. The allocation ratio in intervention and control groups is 1:1.Blinding (masking)Participants and caregivers do not know whether the patient is in the intervention or the control group. The outcome assessor and the data analyst are also blinded to group assignment.Numbers to be randomised (sample size)The calculated total sample size is 60 patients, with 30 patients in each group.Trial statusThe trial began on April 14, 2020 and recruitment is ongoing. Recruitment is anticipated to be completed by June 14, 2020 There has been no change in study protocol since approval, protocol version 1 was approved April 12, 2020.Trial registrationThis trial has been registered by the title of "Effect of Hydroxychloroquine on Novel Coronavirus Disease (COVID-19) prevention in cancer patients under treatment" in Iranian Registry of Clinical Trials (IRCT) with code "IRCT20200405046958N1", https://www.irct.ir/trial/46946.

Project description:ObjectivesPrimary objective: Evaluation of the effect of the proton pump inhibitor (PPI) pantoprazole on the absorption of hydroxychloroquine (HCQ). Secondary objectives: • Evaluation of the relationship between HCQ concentrations in whole blood, plasma and intracellular concentrations in target cells - peripheral blood mononuclear cells (PBMCs). • Evaluation of HCQ as a potential perpetrator in drug-drug interactions at the level of cytochrome P450 (CYP) 3A4 and CYP2D6 (major drug metabolizing enzymes).Trial designSingle centre, open-label, parallel group, two-arm, phase I drug-drug interaction trial.ParticipantsHealthy volunteers (18-60 years old) are treated in the Clinical Pharmacological Trial Center of Heidelberg University Hospital, Germany.Intervention and comparator• Participants are randomized in a group to either receive a nine-day course of pantoprazole, or to a control group without pantoprazole. All participants receive a single dose of HCQ 400 mg. • Additionally, CYP3A4 and CYP2D6 phenotyping with microdosed probe drugs is performed using midazolam and yohimbine as enzyme activity markers, respectively.Main outcomesPrimary endpoint: Area under the curve (AUC)0-72 h and maximum concentration (Cmax) of a single oral dose of 400 mg HCQ with and without pantoprazole (changes in these two values describe relevant aspects of exposure to HCQ with and without administration of pantoprazole). Secondary endpoints: • AUC2-4 h, AUC0-6 h and Cmax of midazolam and yohimbine. • Correlation of HCQ concentrations in whole blood with concentrations in plasma and peripheral blood mononuclear cells (PBMC).RandomisationParticipants are assigned to treatment groups by using a randomisation list (1:1, block size = 4) and consecutive enrolment.Blinding (masking)The trial is an open-label trial, participants and investigators are not blinded.Numbers to be randomised (sample size)A total number of 24 participants (12 per group) are planned to be randomised.Trial statusProtocol version 2.1 dated 24/04/2020, first patient first visit.
