About

Comparison of the effects of CYT107 vs Placebo administered IM at 10μg/ kg twice a week for two weeks on immune reconstitution of lymphopenic COVID-19 patients.

Full description

Approximately forty-eight (48) participants will be randomized 1:1 to receive (a) Intramuscular (IM) administration of CYT107 at 3 μg/kg followed, after 48hrs of observation, by 10 μg/kg twice a week for 2 weeks or (b) Intramuscular (IM) placebo (normal saline) at the same frequency. An interim safety review took place after the first 12 patients. Since the CYT107 was well tolerated, the test dose (3 μg/kg) ceased and the initial dose became the same as the rest of the doses (10 μg/kg). So, the remaining patients will be randomized to receive 5 administrations of (a) CYT107 at 10 μg/kg every 3 to 4 days for 2 weeks 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
