Summary

The purpose of this study was to evaluate the efficacy and safety of eltrombopag in combination with cyclosporine alone as first-line therapy on overall hematologic response

Detailed description

This was an interventional phase II, single-arm, multicenter, open-label, study to investigate the efficacy and safety of the combination of eltrombopag and cyclosporine in treatment-naive, adult subjects with severe aplastic anemia (SAA) as first line therapy. Eligible subjects received eltrombopag and cyclosporine for up to 6 months. Participants who achieved hematologic response any time on or before 6 months were considered as responders; else they were considered as non-responders. Responders at Month 6 discontinued eltrombopag and started to taper cyclosporine until relapse or Month 24, whichever was early. Responders who relapsed prior to 6 months and non-responders discontinued the treatment at 6 months and were followed-up for 30 days. Responders who started to taper cyclosporine and relapsed prior to 24 months discontinued cyclosporine and were followed-up for 30 days.

Conditions

• Severe Aplastic Anemia

Interventions

Type	Name	Description
DRUG	eltrombopag	Film-coated tablets (12.5 mg, 25 mg, 50 mg and 75 mg) administered orally, once daily for up to 6 months. East and Southeast Asian participants were treated with 100 mg once daily, to adjust for the lower apparent clearance of eltrombopag. All other participants were treated with 150 mg once daily.
DRUG	Cyclosporine	Supplied as oral soft gel capsules. The starting dose was based on body weight at 10.0 mg/kg/day (acceptable rounding range was from 9.5 to 10.5 mg/kg/day) in divided doses every 12 hours. After Day 1, dosing was titrated individually according to therapeutic trough level between 200 and 400 μg/L for 6 months. After 6 months (only for responders at Month 6), tapering of cyclosporine was done as follows: * 6-9 months: at the 6 months visit, the dose was reduced by 25% for 3 months * 9-12 months: at the 9 months visit, the dose was further reduced by 25% for another 3 months * 12-24 months: dose was maintained
