Initial therapy
Dexamethasone monotherapy
Regimen variant #1
Immunosuppressive therapy
4-day course
Subsequent treatment
- If platelets remained below 30 x 109/L or bleeding by day 10, course is repeated once
Regimen variant #2
Immunosuppressive therapy, part 1
Immunosuppressive therapy, part 2
21-day cycle for 6 cycles
Regimen variant #3
Immunosuppressive therapy
4-day course
Patients who had an initial response, but whose platelets dropped below 30 x 109/L within 6 months received:
Regimen variant #4, monthly dexamethasone
Immunosuppressive therapy
28-day cycle for 6 cycles
Regimen variant #5, bi-weekly dexamethasone
Immunosuppressive therapy
- Dexamethasone (Decadron) as follows:
- Adults: 40 mg IV or PO once per day on days 1 to 4
- Patients less than 15 years old: 20 mg/m2 (maximum dose of 40 mg) IV or PO once per day on days 1 to 4
- Patients who had platelet counts of less than or equal to 30 x 109/L between cycles and/or who had bleeding related to thrombocytopenia received 0.035 mg/kg PO once per day "between courses"
14-day cycle for 4 cycles
