Randomized, Controlled, Double-blind Clinical Trial Comparing the Efficacy and Safety of Chemoprophylaxis With Hydroxychloroquine in Patients Under Biological Treatment and / or JAK Inhibitors in the Prevention of SARS-CoV-2 Infection
Study Details
Study Description
Brief Summary
The investigators plan to evaluate a strategy of chemoprophylaxis with hydroxyloquine (HCQ) against COVID-19 infection in patients diagnosed with an immunomediated inflammatory disease who are following a treatment with biological agents and / or Jak inhibitors. The strategy will be carried out through a randomised double blind, placebo-controlled clinical trial and will assess comparative rates of infection (prevalence, incidence), severity including mortality, impact on clínical course of the primary diseases and toxicity. Such evaluation will require prospective surveillance to assess the different end-points.
Drug interventions in this protocol will follow the Spanish law about off-label use of medicines.

Outcome Measures
Primary Outcome Measures
- Incidence rate of new COVID-19 cases in both arms [From day 14 after start of treatment up to the end of follow-up: week 27]
number of new cases divided by number of persons-time at risk
- Prevalence of COVID-19 cases in both arms [27 weeks after the beginning of the study]
percentage of cases of COVID 19
- Mortality rate secondary to COVID-19 cases in both groups [27 weeks after the beginning of the study]
Case fatality rate (CFR): the proportion of diagnosed cases of COVID 19 that lead to death
- Intensive Care Unit (CU) admission rate secondary to COVID-19 cases in both groups [27 weeks after the beginning of the study]
percentage of patients who need admission in an ICU due to COVID 19 infection
Secondary Outcome Measures
- Adverse events [12 weeks after the start of treatment]
Presence and type of adverse events at this point.
- Adverse events [27 weeks after the beginning of the study]
Proportion of participants that drop out of study

Data on decompensated liver disease:
to. Aspartate aminotransferase (AST) and / or ALT> 10 x upper limit of normal (LSN).
- Total bilirubin> 25 μmol / l (1.5 mg / dl). c. International normalized index> 1.4. d. Platelet count <100,000 / mm3. 17. Serum creatinine levels> 135 μmol / l (> 1.53 mg / dl) in men and> 110 μmol / l (> 24 mg / dl) in women.
18.Significant kidney disease, including nephrotic syndrome, chronic kidney disease (patients with markers of liver injury or estimated glomerular filtration rate [eGFR] of less than 60 ml / min / 1.73 m2). If an abnormal value is obtained at the first screening visit, the measurement of eGFR may be repeated before randomization within the following time frame: minimum 4 weeks after the initial test and maximum 2 weeks before the planned randomization. Repeated abnormal eGFR (less than 60 ml / min / 1.73 m2) leads to exclusion from the study.Pregnant or lactating women; 19. Inability to consent and/or comply with study protocol; 20. Individuals with known hypersensitivity to the study drugs. 21. Any contraindications as per the Data Sheet of or Hydroxychloroquine.
