简要总结
This is a multi-center, open-label study evaluating the safety of Allocetra-OTS, in 5 subjects with severe COVID-19 and respiratory dysfunction. Subjects, who will be identified as suffering from COVID-19, will be recruited.
After signing an informed consent by the patient and, within 24+6 hours following the time of eligibility (time 0), on Day 1, eligible recipient subjects will receive single intravenous (IV) administration of investigational product as described below.
Subjects will be hospitalized for COVID-19, and later as medically indicated. Following investigational product (IP) administration (Day 1), subjects will be followed for efficacy and safety assessments through 28 days.
详细描述
Study Rationale
COVID-19, the name given to the clinical syndrome associated with the newly recognized virus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become pandemic with a mortality estimated based on reports from China between 1-3% and complications among hospitalized patients leading to up to 15-25% admissions to the Intensive Care Unit (ICU). The clinical presentation includes both upper and lower respiratory tract infection, but patients may also be asymptomatic.
The term "cytokine storm" calls up vivid images of an immune system gone awry and an inflammatory response flaring out of control. The term has captured the attention of the public and the scientific community alike and is increasingly being used in both the popular media and the scientific literature. Indeed, a few publications have indicated an important part of the complications in COVID-19 are related to a cytokine storm.
In that regard, the investigators have recently completed a successful phase 1b clinical trial of immune-modulation in patients with sepsis (NCT03925857).
Taken together, in patients with moderate to severe COVID-19, there may be a comparable underlying immunological mechanism of action that may be similar to the one that was recently shown by us in sepsis, which is a hyper-inflammatory pathway associated with increased death. 40 previous trials using monoclonal antibodies against a single cytokine in septic patients have failed in sepsis pointing out that there is a need to modify the cytokine storm rather than treating with a single anti-cytokine.
