Background:<\/strong>InO, an anti-CD22 antibody-calicheamicin conjugate, showed superior response vs standard care for R\/R ALL in the phase III INO-VATE trial. Herein, effects of prior therapy on response and toxicities were assessed in patients (pts) receiving InO.\u00a0<\/p>\r\n\r\n\r\n\r\n <\/p>\r\n\r\n\r\n\r\n Methods:<\/strong>Per protocol, intent-to-treat analyses of complete remission [CR]\/CR with incomplete hematologic recovery [CRi] included the first 218 of 326 pts randomized (ITT218). The safety population included 139 pts who received \u2265 1 InO dose (max 1.8 mg\/m2<\/sup>\/cycle [0.8 mg\/m2<\/sup>\u00a0on d1; 0.5 mg\/m2<\/sup>\u00a0on d8 and 15 of a 21\u201328 d cycle for \u2264 6 cycles]). Minimal residual disease (MRD) negativity was assessed by central flow cytometry ( < 0.01%). Data as of October 2, 2014 are presented (trial ongoing).\u00a0<\/p>\r\n\r\n\r\n\r\n <\/p>\r\n\r\n\r\n\r\n Results:<\/strong>109 pts in the ITT218 received InO (CR\/CRi rate, 81% [95% CI, 72\u201388]; MRD negativity rate in responders, 78% [95% CI, 68\u201387]; median remission duration [DoR], 4.6 [95% CI, 3.9\u20135.4] mo). 67% and 32% of pts received InO as salvage (S) 1 and S2 (missing, n = 1). For S1 vs S2, response was numerically higher, MRD-negativity was similar, and DoR was numerically longer (Table). CR\/CRi rate was numerically lower for pts with (n = 17) vs without (w\/o) (n = 92) prior SCT (77% [95% CI, 50\u201393] vs 82% [72\u201389]). In the safety population, Gr \u2265 3 febrile neutropenia rates were similar for S1 (n = 95) vs S2 (n = 43) (both 23%) and for pts with (n = 24) vs w\/o (n = 115) prior SCT (29% vs 23%). Any grade hepatobiliary AE rates were significantly higher in S2 vs S1 (47% vs 17%;\u00a0P<\/em>< 0.001) and numerically higher for pts with vs w\/o prior SCT (42% vs 23%). For S1 vs S2, 36 vs 11 pts had poststudy SCT. Veno-occlusive liver disease (VOD) including post-SCT VOD occurred in 8% of S1 vs 16% of S2 pts (2 fatal in S1); in 21% with vs 9% w\/o prior SCT (1 fatal in each cohort).\u00a0<\/p>\r\n\r\n\r\n\r\n <\/p>\r\n\r\n\r\n\r\n Conclusions:<\/strong>InO may provide clinical benefit in pts with R\/R ALL for both S1 and S2 therapy; hepatotoxicity risk increases with number of prior therapies and prior SCT.
