COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

• Receiving supplemental oxygen, due to respiratory failure, with PaO2/FiO2 ratio less than or equal to 200 (moderate to severe) or an SaO2 < 92% while receiving more than or equal to 4 litres of O2 via face mask.

• Documented significant chronic obstructive airway disease
• Death is imminent and inevitable within 24 hours,

Type of endpoint(s)
Statistical methods / analysis
Treating the primary outcome as a continuous response, 20 subjects in each arm are needed to detect a difference of one standard deviation with 85% power, 2-sided p value 0.05 (No available data on VFD with COVID-19 patients, a report from Seattle suggested ventilation time SD 3.7d). As this is a feasibility pilot study, the point estimate of 95% Confidence Interval for the primary outcomes will be used to describe the potential impact of AECs treatment when compared with vehicle administration.
All analysis will be on the intention-to-treat principle. Median regression will be used to assess the primary outcome. Bonferroni adjustment for multiplicity will be used for secondary outcomes. Standard statistics will be used to describe baseline data.
Binomial secondary outcomes including 28 days all-cause mortality will be assessed using logistic regression to derive odds ratios. Time from randomisation to intubation, and ICU stay will be analysed using sub-distribution hazard regression models to account for the competing risk of death.

Brief summary
Already, there are five clinical trials registered at Monash Health to assess the safety and efficacy of allogeneic amniotic epithelial cells for (i) bronchopulmonary dysplasia; (ii) acute ischaemic stroke; (iii) compensated liver cirrhosis; and (iv) Crohn’s related perianal fistulas. To date, 27 individuals (17 neonates, 10 adults) have received allogeneic amniotic epithelial cells intravenously. No serious adverse events associated with cell administration or tumorigenesis have been reported. Preclinical biodistribution studies indicate that the AECs do not engraft and are not detected in any tissues after 5 days. Intravenous infusions of up to 8 million cells per kilogram have been well tolerated in extremely premature babies.
Based on our extensive preclinical and clinical expertise with AEC, we propose a Phase 1b/2a trial to assess the safety and efficacy of allogeneic AECs for the treatment of COVID-19 related respiratory illness and multi-organ complications.
