Lower-risk Myelodysplastic Syndromes
Conditions
Brief summary
This study aims to compare the efficacy and safety of recombinant human thrombopoietin (rhTPO) + cyclosporine (CsA) and CsA monotherapy in the treatment of lower-risk myelodysplastic neoplasms with thrombocytopenia.
Interventions
rhTPO 300U/kg/d, subcutaneous injection, once a month for 14 consecutive days
CsA 3-5mg/kg/d

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| HI-P | 1-month, 2-month, 3-month, 6-month | hematological response - platelet |
| ORR | 1-month, 2-month, 3-month, 6-month | ORR=CRR+PRR+HI |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of bleeding incidents and severity assessed by the World Health Organization Bleeding Scale | 3-month, 6-month | minimum value = 0, maximum value = 4; higher scores indicate worse outcome |
| Platelet transfusion independence | 3-month, 6-month | according to the number and interval of platelet transfusions |
| Time to CR/OR | through study period, an average of 6 months | Time from baseline to first response |
| Duration of HI-P | through study period, an average of 6-month | Time to patients achieving HI-P to losing response |
| Quality of life score measured by the Short Form-36 Health Survey | 3-month | minimum value = 0, maximum value = 100; higher scores indicate better quality of life |
| Clonal evolution | 12-month | The incidence of elevation of blast cells in bone marrow and peripheral blood within one year, and the incidence of progressing to higher-risk MDS or AML within one year |
| OS | 12-month | Overall survival (OS), defined as the time from randomization/treatment start to death from any cause. |
