Nationwide survey on the use of eltrombopag in patients with severe aplastic anemia: Report on behalf of the french reference center for aplastic anemia

BACKGROUND:

Few therapeutic options are currently available for patients (pts) with severe aplastic anemia (SAA) refractory to antithymocyte globulin (ATG) plus ciclosporine (CsA) and not eligible for allogeneic stem cell transplantation. It has recently been reported that eltrombopag (ELT), a TPO receptor agonist, is efficient to improve tri-lineage blood counts in this setting. However, real-life use of this drug is still largely unknown. In pts with SAA refractory to ATG, physicians can accede to ELT in France through a compassionate use program. We took advantage of this program to assess the efficacy and safety of ELT in SAA pts.

PATIENTS AND METHODS:

The French National Reference Center for Aplastic Anemia conducted identified (already seen at SAA diagnosis), and karyotype was a failure in 1 pt.

CONCLUSION:

We report here the first real-life multicenter study about the use of ELT in SAA. In a particular severe pts population with no other treatment possibility, we confirm a 40% rate of hematological improvement with transfusion independence. Some of the pts who were not eligible to ATG plus CsA (comorbidities) also received ELT first line with similar response rates. Elderly pts unfit for ATG may thus benefit from this treatment which at the best should be given through prospective clinical trials. (Figure Presented).
