Intervention(s)
|
1. The administration of rATG; 2.5 mg/kg, iv. daily, day 1 - day 5 + CsA; 5 mg/kg, po. bid (before breakfast and before dinner) +adrenalcorticosteroid (the dose is mentioned after) is started. CsA used is Neoral or generic drug emulsified in the same way with Neoral. A blood level of CsA is measured and the dose which CsA blood level 2 hours after oral administration (C2) reachs 600 - 900 ng/mL is adjusted. The investigator shall reduce the dose of CsA by 25% on this occasion when blood trough level (C0) just before the administration is beyond 250 ng/mL because renal function disorder may occur (2). When serum creatinine level also becomes higher than 150% of baselines, the 25% dose reduction of CsA shall be performed. If C2 did not reach to 600 ng/mL, then dose of CsA is appropriately increased. 2. EPAG; 75 mg, po. daily (before sleep, requires to pass more than at least 2 hours after dinner) is started from day 6. 3. The dose of steroid is as follows: Day 1 - day 5: methylprednisolone 2 mg/kg/day Day 6: Methylprednisolone 1 mg/kg/day Day 8, 10, 12, 14, 16, 18, 20: prednisolone 0.5 mg/kg/day Discontinuation after day 21 4. The administration of CsA and EPAG is continued for 26 weeks. When it passed 26 weeks, further treatment mentioned above is entrusted to the investigator in each medical institution after 27 weeks if patients reached Camitta criteria CR or PR. However, the administration is continued for 52 weeks even if the dose of CsA is reduced. The treatment after 53 weeks is not specified. If patients did not reach CR or PR at 26 weeks, treatment after 27 weeks is entrusted to the investigator in each medical institution (it is not specified in this study).
