Trial Outcomes & Findings for Tregs for the Treatment of Acute Respiratory Distress Syndrome (ARDS) Associated With COVID-19 (regARDS) (NCT NCT05027815)
NCT ID: NCT05027815
Last Updated: 2023-06-05
Results Overview
DLT is defined as any related treatment-emergent adverse event (TEAE) with a National Cancer Institute Common Terminology Criteria for Adverse Events Version 5.0 (NCI CTCAE 5.0) grade ≥ 3 which also represents a shift from baseline clinical status of ≥ 1 NCI CTCAE grade
TERMINATED
PHASE1
7 participants
28 days post infusion

Participant Flow
Participants were recruited from participating medical centers with the first participant consented September 23, 2021 and the last participant consented February 10, 2022.
Of 7 participants consented, 4 met eligibility criteria and were assigned to a treatment arm. Three were enrolled in the 100x10\^6 cells arm, and one was enrolled in the 200 x 10\^6 cells arm.
