InterLeukin-7 to Improve Clinical Outcomes in Lymphopenic pAtients With COVID-19 Infection ( ILIAD-7-US-I )
- Registration Number
- NCT04442178
- Lead Sponsor
- Revimmune
- Brief Summary
Comparison of the effects of CYT107 vs Placebo administered 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

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 11 steps WHO clinical improvement score
