Background

The ATHENA trial was designed to compare everolimus [EVR] in combination with tacrolimus [TAC] or cyclosporine A [CyA] vs. a standard of mycophenolic acid [MPA] and TAC in de novo kidney transplant [KTx] recipients.

Methods

In this 12 months [M], prospective, open-label, randomized study with 15 German and 12 French sites, 612 patients [pts] were randomized 1:1:1 at time of Tx to either EVR (3-8ng/ml M1-M12) +TAC (4-8ng/ml M1-M3; 3-5ng/ml M3-M12), or EVR (3-8ng/ml M1-M12) + CyA (75-125ng/ml M1-M3; 50-100ng/ml M3-M12) or to control TAC regimen (4-8ng/ml M1-M3; 3-5ng/ml M3-M12) with MPA. All pts continued on steroids. Herein we report M12 outcomes on infections and CMV events from ITT with 208 EVR+TAC pts, 199 EVR+CyA pts and 205 TAC+MPA pts.

Results

From randomization to M12 total incidences of infections were 73% in EVR+TAC and 72% in EVR+CyA treated pts vs 82% in TAC+MPA pts. Whilst incidences of bacterial infections were similar between the three treatment groups (44% EVR+TAC, 43% EVR+CyA, 42% TAC+MPA) major differences were seen for viral infections with incidences of 41% in TAC+MPA vs only 26% in EVR+TAC and 12% in EVR+CyA groups. Incidence of BKV events was 23% in TAC+MPA vs 17% in EVR+TAC vs 9% in EVR+CyA pts (p<0.01). CMV events occurred two thirds less in EVR treated pts compared to TAC+MPA control group with an incidence of 21% in TAC+MPA vs 6% for EVR+TAC and 3% for EVR+CyA treatment pts (p<0.001).

Conclusion

ATHENA as largest European KTx study confirmed comparable efficacy and safety together with less viral infections for EVR-based treatment groups compared to TAC+MPA group. A significant, protective effect of EVR-based regimens vs CMV/BKV events was robustly confirmed.
