Brief summary
The primary objective of this phase 2, multicentric, placebo-controlled double-blind, randomized study is to evaluate the efficacy of the combination of hydroxychloroquine and azithromycine on the viral load drop at day 5 among patients with COVID-19 and hematological malignancies.
Detailed description
The study will evaluate the effect of the combination of hydroxychloroquine and azithromycine versus placebo among 114 patients with COVID-19 and hematologic malignancy. After randomization in 1:1 ratio, patients will receive either the study treatment or placebo : * Patients enrolled in the experimental arm will receive hydroxychloroquine (200mgx3 tablets per day during 10 days) and azithromycine (500 mg at day 1 then 250mg per day during 4 days) * Patients enrolled in the control arm will receive a placebo of hydroxychloroquine (3 tablets per day during 10 days) and a placebo of azithromycine (2 capsules at day 1, then 1 capsule per day during 4 days)
Interventions
Hydroxychloroquine is an anti-malarial drug also used as anti-inflammatory treatment for systemic lupus erythematosus and rheumatic disorders. HCQ also inhibits pH-dependant replication stages of diverse types of viruses including flavivirus, retrovirus and coronaviruses.
Azithromycin is amacrolide antibiotic.
Placebo of Hydroxychloroquine Sulfate 200 MG \[Plaquenil\].
Placebo of Azithromycin capsules.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Evaluation of the efficacy of hydroxychloroquine and azithromyncine on the viral load drop at day 5. | 5 days of treatment | Locally evaluated rate of viral response. Favorable response is defined as (1) complete response : negative PCR (absence of detectable signal with a minimum of 40 cycles) or (2) major response : detectable signal but with an increased number of cycles \> or egal to 10 compared to initial PCR. Response failure is defined as (1) minor response : detectable signal but with an increased number of cycles \< 10 compared to initial PCR or (2) stabilisation or worsening of the viral load. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of patients progressing to a severe form | up to 3 months | Less or equal to 94% oxygen saturation - need to initiate oxygenotherapy - occurrence of respiratory distress - patient transfer in intensive care unit - need of mechanical ventilation - occurrence of non-respiratory organ failure - occurrence of septic shock |
| Mortality | up to 1 and 3 months | Date and cause of death |
| Evaluation of viral load drop | at day 10 | SARS-CoV-2 viral load by PCR on nasopharyngeal swab at day 10 (if positive at day 5) : rate of negativation and comparison of number of cycles with previous samples |
| Tolerance of study treatment | up to 3 months | Frequence and causality of all-grade cardiac adverse events - frequence and causality of grade \> 1 adverse events for other adverse events - frequence and causality of serious adverse events (CTCAE v5) |
| Evaluation of the seroconversion | at inclusion, day 10, day 30 and day 90 after treatment | Collection of serum to realize serological tests |
| Clinical evolution | up to 3 months | Duration of fever - duration of respiratory symptoms (cough, dyspnea) - duration of other COVID-19 related symptoms (digestive symptoms, ageusia, anosmia) |
| Hospitalisation duration | up to 3 months | Duration of hospitalisation (conventional, intensive care, reanimation) |
| Impact of the study treatment on the treatment of the hematological disease | up to 3 months | Patient follow-up during 3 months : hematological status and associated therapy |
| Monitoring of the QT space | at inclusion, day 2, day 5, day 10 | ECG (using connected machine to allow monitoring at home) |
| Dosage of residual concentration of azithromycine and hydroxychloroquine. | at day 5 and day 10 | Dosage of residual concentration of azithromycine and hydroxychloroquine. |
| T immunological study | at day 10 and day 30 after treatment | Phenotypic and functional study of T lymphocytes at inclusion, Retrospective analysis on frozen cells. |
| NK immunological study | at day 10 and day 30 after treatment | Phenotypic and functional study of NK lymphocytes at inclusion, Retrospective analysis on frozen cells. |
