Detailed Description
This open-label, dose-escalation Phase I study plans to evaluate the safety, tolerability, and efficacy of MatriPlax.
This is a conventional 3+3 dose-escalation study in which subjects with moderate or severe ARDS will receive intravenous MatriPlax infusion.
Participants will be assigned to one of three dose cohorts (low, middle and high doses of MatriPlax), depending on the time of their enrollment. Each participant will receive two doses of MatriPlax on Day 1 and Day 4. Each dose cohort will have three to six subjects enrolled sequentially with at least 1 week in between. All participants will be followed until 12 months after receiving MatriPlax or withdrawal from the study.
A Data Safety and Monitoring Board (DSMB) meeting will be held when all participants of each cohort complete their 28-day of treatment and evaluation period. The DSMB will determine if the study is safe to proceed to the next dose level or it requires to recruit more subjects to the concurrent dose level for safety evaluation.
