| Scientific title | A multicentre, phase II, open-label, randomised controlled trial of repeated autologous infusions of granulocyte colony stimulating factor (GCSF) mobilised CD133+ bone marrow stem cells in patients with cirrhosis |
| Study acronym | REALISTIC |
| Study objectives | Animal data suggests that haematopoietic stem cells (HSCs) and granulocyte colony stimulating factor (GCSF) play an important role in increasing hepatic regeneration and reducing hepatic fibrosis. This study aims to demonstrate the superiority of either GCSF alone or GCSF followed by repeated infusions of HSCs (CD133+ bone marrow stem cells) over standard conservative management in improving severity of liver disease over three months. |
| Ethics approval(s) | Submitted to Oxfordshire Research Ethics Committe A, decision due May 2009 |
| Health condition(s) or problem(s) studied | Liver cirrhosis |
| Intervention | Trial Group 1: Standard conservative management Trial Group 2: GCSF (Lenograstim) 15 µg/kg subcutaneously daily for 5 days Trial Group 3: GCSF (Lenograstim) 15 µg/kg subcutaneously daily for 5 days, followed by leukopharesis, isolation of CD133+ cells and reinfusion on day 6, day 30 and day 60. |
| Intervention type | Drug |
| Phase | Phase II |
| Drug / device / biological / vaccine name(s) | Granulocyte colony stimulating factor (GCSF) (Lenograstim) |
| Primary outcome measure(s) |
Change in MELD score (delta MELD) from baseline (day 0) to day 90 |
| Key secondary outcome measure(s) |
1. Changes from baseline to day 90, day 180 and day 360 in: |
