Decidual Stromal Cells as Treatment for Acute Graft Versus Host Disease, a Phase 1-2 Study

Phase 1

• Conditions: Graft vs Host Disease

• Registration Number: NCT02172937
• Lead Sponsor: Karolinska Institutet

Brief Summary

The purpose of this study is to evaluate safety and efficacy using decidual stromal cell therapy for graft versus host disease after allogeneic hematopoietic stem cell transplantation. The hypothesis to be tested is that the cells are safe to infuse and that they have a positive clinical effect.

Detailed Description

Patients with GVHD grade 2-4, will receive decidual stromal cells at approximately 1-2x10\^6 cells/kg at one or more occasions dependent on clinical response.

Primary Outcome Measures

Name	Time	Method
Actuarial survival at six months after first DSC infusion	6 months after inclusion

Secondary Outcome Measures

Name	Time	Method
Incidence of severe infections	Up to one year after inclusion	Severe bacterial, viral and fungal infections.
Response at 168 days after onset of graft versus host disease	Up to 168 days after inclusion	Response will be measured as: * Partial response (PR) if the patient has improved one grade in the overall GvH.; * Complete response (CR) if the patient is free of GvH.; * Non responder (NR) if the patient does not improve after treatment.
Side effects	Up to 6 months after inclusion	Adverse effects related to the treatment.
Disease free survival	Up to one year after inclusion	Survival free from relapse.
Response at 28 days after onset of graft versus host disease	28 days after inclusion	Response will be measured as: * Partial response (PR) if the patient has improved one grade in the overall GvH.; * Complete response (CR) if the patient is free of GvH.; * Non responder (NR) if the patient does not improve after treatment.
Response at 84 days after onset of graft versus host disease	Up to 84 days after inclusion	Response will be measured as: * Partial response (PR) if the patient has improved one grade in the overall GvH.; * Complete response (CR) if the patient is free of GvH.; * Non responder (NR) if the patient does not improve after treatment.
