InterLeukin-7 to Improve Clinical Outcomes in Lymphopenic pAtients With COVID-19 Infection ( ILIAD-7-US-I )

Phase 2
Terminated
Conditions
COVID-19
Lymphocytopenia
Interventions
Drug: Placebo
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
