About

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

Full 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 7 administrations 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 is dedicated to oncology patients

Inclusion criteria

A written, signed informed consent, or emergency oral consent, by the patient or the patient's legally authorized representative, and the anticipated ability for participant to be re-consented in the future for ongoing Study participation

Patients with unresolved grade > 2 toxicities from prior chemotherapy, immunotherapy, or CAR-T cell therapy
Patients with past history of Solid Organ transplant.
Active tuberculosis, uncontrolled active HBV or HCV infection, HIV with positive viral load.
Hospitalized patients with refractory hypoxia, defined as inability to maintain saturation >85% with maximal available therapy for >6 hours
