Developmental phase

Assessment
Primary outcomes Hematologic improvement in the erythrocyte (HI-E) and platelet (HI-P) count according to IWG response criteria 2006 at 8 weeks after CsA therapy.
Key secondary outcomes 1.Increment of reticulocyte >=20,000/mm3 at 8 weeks after the initiation of CsA.
2.HI-E or HI-P at 4 weeks, 16 weeks and 52 weeks after the initiation of CsA.
3.Increment of reticulocyte >=20,000/mm3 at 4 weeks, 16 weeks and 52 weeks after the initiation of CsA.
4.Correlation between HI-E or HI-P at 8 weeks after the initiation of CsA and the following biomarkers; presence of increased PNH-type cells, presence of cells with HLA class I allele-lacking leukocytes, and plasma thrombopoietin.
5.Correlation between HI-E or HI-P at 8 weeks after the initiation of CsA and somatic gene mutations.
6.Time to HI-E or HI-P after the initiation of CsA.
7.Incidence of somatic mutations in granulocyts.
8.Adverse events >=grade 3 associated with CsA therapy.

Medicine
Interventions/Control_1 1. Start CsA (Neoral or generic drugs emulsified in the same way as Neoral) at a dose of 3.5 mg/kg, bid (before breakfast and before dinner).
2. Measure the blood concentration of cyclosporine at 2 hours (C2) after taking the drug and determine the minimum dose of cyclosporine that produces C2 >600 ng/mL. Continue the dose of cyclosporine for 8 weeks.
3. Continue the treatment for further 44 weeks (a total of 52 weeks) when patients meet the response criteria of HI-E or HI-P at the end of the 8 week treatment. Treatments after the 52 weeks are not specified. When patients do not meet the IWG response criteria 2006 at the end of 8 weeks, the treatment is terminated and treatments after 9 weeks are not specified.
