Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Other- Mesenchymoangioblast-derived mesenchymal stem cells (CYP-001)

Intervention group: Mesenchymoangioblast-derived mesenchymal stem cells (CYP-001) at a dose of 2 million cells/kg (up to a maximum of 200 million cells) by IV infusion on two occasions (Day 1 and Day 3) PLUS standard of care in ICU

Control group: standard of care in ICU

The active agent in CYP-001 is allogeneic mesenchymoangioblast-derived mesenchymal stem cells (MCA-derived MSCs), which are produced using the proprietary Cymerus™ platform technology. Cymerus™ refers to the process of generating cell-based products from intermediate cells, MCAs, which in turn are derived from induced pluripotent stem cells or iPSCs. The iPSCs used in the Cymerus™ process were derived from blood donated by a fully-consented healthy adult donor, and were reprogrammed using a transgene-free, viral-free and feeder-free technique.
The PI or authorised designee will ensure that the study treatment at site is safely handled and administered in compliance with requirements. The infusion of the treatment itself will last no longer than 40 minutes, at a rate of 1mL/min, administered via ICU staff.

Outcomes
Primary outcome [1] 323814 0
To evaluate the early efficacy of CYP-001 in adults with respiratory failure being treated in intensive care units (ICU), based on improvements in P/F ratio compared to controls. This outcome is defined as a trend in trajectory of P/F ratio between groups by day 7. P/F ratio is collected from ventilatory support data combined with arterial blood gas measures
Timepoint [1] 323814 0
By day 7 in the study (within days 1-7). P/F ratio will be collected as per routine standard collection of data to inform respiratory function (at least 4 hourly when relevant) plus every 15 minutes during cell adminstration and 1, 2, 3, 4 and 5 hours after
Primary outcome [2] 323815 0
To assess the safety and tolerability of CYP-001 in adults with respiratory failure being treated in ICU measured by the incidence and severity of treatment-emergent adverse events (including events related with reactions to cryoprotectant; fever read from digital thermometer, allergy, olfactory/taste disturbances), safety laboratory evaluations (immunology screen with full blood examination) and vital signs (including significant fluctuations from clinically acceptable BP, and HR and SaO2 levels measured via pulse oximetry)
Timepoint [2] 323815 0
Up to day 28 in the study. On days 0-7 this will be collected routinely in standard care (at least 4-hourly) plus every 15 minutes during cell administration and 1, 2, 3, 4 and 5 hours after, then daily after day 8
Secondary outcome [1] 382972 0
To evaluate the early efficacy of CYP-001 in adults with respiratory failure being treated in ICU, measured by changes in blood inflammatory marker, C-reactive protein
Timepoint [1] 382972 0
Up to day 7 after patient enrolment in study, collected as part of standard care pathology analysis occurring daily
Secondary outcome [2] 382974 0
To evaluate the early efficacy of CYP-001 in adults with respiratory failure being treated in ICU, based on changes in physiological indices of respiratory dysfunction (including exploratory measures of P/F ratio, respiratory rate, oxygenation index (OI), respiratory compliance, positive end-expiratory pressure (PEEP), fever monitoring, ICU length of stay, ventilator free days (VFDs)) from data collected routinely in standard care (i.e. records of extubation, reintubation) up to day 28.
Timepoint [2] 382974 0
Up to day 28 after patient enrolment in study, collected as per routine standard collection of data to inform respiratory function (at least 4 hourly when relevant) and at the same intervals as P/F ratio
Secondary outcome [3] 383086 0
To evaluate the early efficacy of CYP-001 in adults with respiratory failure being treated in ICU, based on proportional differences between groups on the Clinical Improvement Scale
Timepoint [3] 383086 0
Assessed on day 28 after patient enrolment in study, based on health and hospitalisation status
Secondary outcome [4] 383087 0
To evaluate the early efficacy of CYP-001 in adults with respiratory failure being treated in ICU, based on proportional differences between groups in Quality of Life and Disability assessments measured by the 36-Item Short Form Survey (SF-36)
Timepoint [4] 383087 0
Assessed on day 28 after patient enrolment in study
Secondary outcome [5] 383221 0
To evaluate the early efficacy of CYP-001 in adults with respiratory failure being treated in ICU, based on proportional differences between groups in Quality of Life and Disability assessments measured by the Standardised Mini-Mental State Examination (SMMSE)
Timepoint [5] 383221 0
Assessed on day 28 after patient enrolment in study
