Registration Number
NCT04392128
Lead Sponsor
Institut de cancérologie Strasbourg Europe
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)

Primary Outcome Measures
NameTimeMethod
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 Outcome Measures
NameTimeMethod
Dosage of residual concentration of azithromycine and hydroxychloroquine.at day 5 and day 10

Dosage of residual concentration of azithromycine and hydroxychloroquine.

Mortalityup to 1 and 3 months

Date and cause of death

Evaluation of the seroconversionat inclusion, day 10, day 30 and day 90 after treatment

Collection of serum to realize serological tests

Impact of the study treatment on the treatment of the hematological diseaseup to 3 months

Patient follow-up during 3 months : hematological status and associated therapy
