Interventions
|
Open label, randomized, controlled study of G-CSF, ATG and Cyclosporin A, versus ATG and Cyclosporin A. Subjects will be evaluated for hematologic response through day 240. Subjects who do not demonstrate a partial or complete remission by day 120 will be randomized to receive either a second course of ATG or continue their current regimen. Subjects who do demonstrate a partial or complete remission will continue their current regimen through day 240 or maintenance of a complete remission for 30 days. The last day of study treatment will be day 240.
|
|
Primary outcome measure(s)
|
To evaluate the effect of G-CSF on failure free survival and mortality in study subjects also receiving ATG and Cyclosporin A. Also time to hematologic response (failure defined as death, non-response or requirement of further treatment).
|
|
Secondary outcome measure(s)
|
1. The proportion of subjects who achieve a hematologic response
2. The incidence of severe infections
3. The benefit due to the addition of G-CSF on death rate, days of hospitalization, and duration of antibiotic treatment
4. Time to achieving a complete remission within 120 days
5. Proportion of subjects who achieve a complete remission within 120 days
6. The relapse rate among responders
7. Median blood counts among subjects who achieve transfusion independence
8. The proportion of subjects who have a change in severity of disease (e.g. improvement from very severe to severe aplastic anemia)
9. Proportion of subjects who respond to re-treatment with ATG
10. The safety of G-CSF in subjects treated with G-CSF, ATG and Cyclosporin A, compared to subjects who receive ATG and Cyclosporin A
