Study Arms (2)

Cohort A

EXPERIMENTAL

Mesenchymoangioblast-derived mesenchymal stem cells (CYP-001) at a dose of 1 million cells/kg (up to a maximum of 100 million cells) by IV infusion on two occasions (Day 0 and Day 7)

Biological: Mesenchymoangioblast-derived mesenchymal stem cells

Cohort B

EXPERIMENTAL

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 0 and Day 7)

Biological: Mesenchymoangioblast-derived mesenchymal stem cells

Interventions

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.

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Diagnosis using consensus grading with steroid-resistant Grade II-IV acute GvHD, after a haematopoietic stem cell transplant for a haematological disorder.
  • Life expectancy of at least one month.
  • Agree to have follow-up data collected for two years after their initial dose of CYP-001 (under a separate protocol).

You may not qualify if:

  • Pregnant or breastfeeding or plan to become pregnant within three months of receiving their last dose of CYP-001.
  • Have received any investigational research agent within 30 days or five half-lives (whichever is longer) prior to the first dose of IMP.
  • Known or suspected current alcohol or substance abuse problem.
  • Progressive or relapsing haematological malignancy, a current solid tumour, or previous malignant solid tumour that is likely to recur during the period of the study (with the exception of a past history of basal or squamous cell carcinomas).
  • Heart failure (NYHA Functional Class II-IV) and/or pulmonary failure.
  • Haemodynamically unstable and/or at high risk of cardiovascular events.
  • Terminal organ failure.
  • Meningitis, pneumonia with hypoxemia, HIV or another severe or uncontrolled systemic infection, which in the opinion of the investigator is likely to impact on the ability of the patient to participate in the trial.
