About this study
Official title: An Open-Label Phase 1 Study to Investigate the Safety and Efficacy of CYP-001 for the Treatment of Adults With Steroid-Resistant Acute Graft Versus Host Disease
The purpose of this study is to assess the safety, tolerability and efficacy of two infusions of CYP-001 in adults with steroid-resistant GvHD.
Read the detailed description
This is a multi-centre, open label, dose escalation study to assess the safety, tolerability and efficacy of two infusions of CYP-001, in adults who have steroid-resistant GvHD.
Participants will receive standard of care treatment throughout the study, according to local procedures. The first eight participants will be enrolled in Cohort A and receive a CYP-001 dose of 1 million cells per kg, up to a maximum dose of 100 million cells, on Day 0 and Day 7. Subject to a safety review of data from Cohort A, an additional eight participants will be enrolled into Cohort B and receive a CYP-001 dose of 2 million cells/kg, up to a maximum dose of 200 million cells, on Day 0 and Day 7. The primary evaluation period concludes for each participant 100 days after the first dose of CYP-001. Participants will have study visits on Days 0, 3, 7, 14, 21, 28, 60 and 100. Subsequently, participants will enter a long term follow-up period, which concludes 2 years after the first dose of CYP-001.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Mesenchymoangioblast-derived mesenchymal stem cellsBiological
Also called CYP-001
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.
| Study group | Role | What they receive |
|---|---|---|
| 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) Receives: 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) Receives: Biological: Mesenchymoangioblast-derived mesenchymal stem cells |

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Mesenchymoangioblast-derived mesenchymal stem cells in people with Graft vs Host Disease, run by Cynata Therapeutics Limited at 7 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 11 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites in United Kingdom, Australia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence and severity of treatment emergent adverse events [safety and tolerability] (time frame: 28 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02923375, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Aug 2020; AzTrials last refreshed its copy on 8 Nov 2026.
