InterLeukin-7 to Improve Clinical Outcomes in Lymphopenic pAtients With COVID-19 Infection (Brazil Cohort)
- Registration Number
- NCT04927169
- Lead Sponsor
- Revimmune
- Brief Summary
Comparison of the effects of CYT107 vs Placebo administered by intra-muscular route (IM) at 10μg/kg twice a week for three weeks on immune reconstitution of lymphopenic COVID-19 patients
- Detailed Description
Approximately forty-eight (48) participants will be randomized 1:1 to receive
(a) Intramuscular (IM) administration of CYT107 at 10 μg/kg followed, after 72hrs of observation, by 10 μg/kg twice a week for 3 weeks (maximum 7administrations adjusted to patient's length of stay in the hospital) or (b)Intramuscular (IM) placebo (normal saline) at the same frequency. The aim of the study is to test the ability of CYT107 to produce an immune reconstitution of these patients and observe possible association with a clinical improvement.
This cohort excludes oncology patients on treatment

Group Intervention Description CYT107 Interleukin-7 IM administration of CYT107 / Interleukin-7 PLACEBO PLACEBO IM administration of Saline at the same volume
- Primary Outcome Measures
Name Time Method Change of the absolute lymphocyte count (ALC) of lymphopenic (ALC≤1000/mm3) COVID-19 infected participants out to approximately 30 days following initial Study drug administration or Hospital discharge (HD), whichever occurs first one month A statistically significant increase of the absolute lymphocyte count (ALC) from randomization to day 30 or Hospital Discharge
- Secondary Outcome Measures
Name Time Method To obtain "clinical improvement" as defined by an improvement in a 11-points WHO score for Clinical Assessment, through day 30 or HD. one month to determine if CYT107 will improve the clinical status of hospitalized COVID-19 patients as measured by the 11 points WHO clinical score
a significant change of SARS-CoV-2 viral load through day 30 or HD one month The decrease of SARS-CoV-2 viral load from measurements at baseline and days of treatment dose 4 and dose 5, Day 21 and Day 30 or HD (whichever occurs first)
