Tregs for the Treatment of Acute Respiratory Distress Syndrome (ARDS) Associated With COVID-19 (regARDS)

Tregs are a subset of CD4+ T cells that function to maintain immune system balance. The function of Tregs in maintaining immune tolerance can be harnessed through Treg cell therapy for treating various immunological diseases. Adoptive Tregs therapies have been shown to be effective in dozens of animal models, including models of virus-induced ARDS. This is a Phase 1 study to evaluate the safety and tolerability of cePolyTregs in subjects with ARDS associated with SARS-CoV-2 infection. The study is an open-label Phase 1 study to assess escalating doses of cePolyTregs administered as a single IV dose. The study will include up to 3 cohorts of 3 to 6 subjects/cohort followed for a total of 12 weeks. All subjects will receive standard of care treatment for COVID-19, including dexamethasone per institutional guidelines and other approved therapies for ARDS associated with SARS-CoV-2 infection per institutional guidelines.
