Now you can aim higher in R/R ALL1-5

The pivotal registration study for BESPONSA (N=164 [164 received treatment]) was an open-label, dual arm, randomised Phase III study in patients aged 18 or over with relapsed or refractory CD-22, Ph+ or Ph- ALL versus investigator’s choice of standard chemotherapy (N=162).1  
The 2 primary endpoints were complete remission (including complete remission with incomplete haematologic recovery) and overall survival

INO-VATE ALL study design​​​​​​​1-2​​​​​​​

*All Ph+ patients must have been unresponsive to prior treatment with ≥1 second-/third-generation TKI and standard induction chemotherapy1,6
​​​​​​​ Number of Ph+ patients enrolled was capped at 20%, total n = 22/164 in the BESPONSA arm, n = 27/162 in the SC arm.2
†≥ 5% bone marrow blasts on local morphological analysis
​​​​​​​ALL, acute lymphoblastic leukaemia; AraC, cytarabine; CR, complete remission; CRi, complete remission with incomplete haematological recovery of peripheral blood counts; FLAG, fludarabine/AraC/granulocyte colony-stimulating factor; HiDAC, high-dose AraC; MXN, mitoxantrone; OS, overall survival; Ph+/–, Philadelphia chromosome-positive/-negative;
R/R ALL, relapsed/refractory acute lymphoblastic leukaemia; SC, standard chemotherapy; TKI, tyrosine kinase inhibitor

Response rates (CR/CRi)​​​​​​​1

Aim for improved CR/CRi rates vs SC

In the INO-VATE study, 4 out of 5 patients achieved the primary endpoint of CR/CRi with single agent BESPONSA1*

*CR/CRi rates in the remission-analysis population, which include the first 218 patients who underwent randomisation in the intention-to-treat population (inotuzumab ozogamicin, n = 109; standard chemotherapy, n = 109).
Endpoint was complete remission or complete remission with incomplete haematological recovery.

CI, confidence interval; CR, complete remission; CRi, complete remission with incomplete haematological recovery of peripheral blood counts, SC, standard chemotherapy.

Long term Overall Survival

Aim to increase long-term survival rates

A long-term OS analysis from the INO-VATE study reports longer OS with BESPONSA vs SC2

INO-VATE OS: Data across 50 months (data cut: January 2017); median OS follow-up: 29.6 (range, 1.7-49.7) months2

HR 0.751 (95% CI, 0.588–0.959, Two-sided p = 0.0210)5

Adapted from: Kantarjian HM, et al. 2019.2

BESPONSA more than trebled the 3-year Median OS rate vs SC (20.3% vs 6.5%)2. Overall HR for survival was 0.751 (95% CI, 0.588–0.959; 2-sided p-value = 0.0210)5​​​​​​​​​​​​​​

MRD rates by cycle

Aim for MRD negativity in cycles 1 and 24

In the full study population, of 164 BESPONSA patients 92 patients achieved CR/CRi with MRD negativity

Study populations

Timing of cumulative MRD negativity in patients achieving MRD-negative CR/CRi    (n = 92)4

*Patients with ≥ 1 MRD measurement < 0.01% within each cycle; patients who had MRD < 0.01% previously not included. MRD negativity is defined as minimum MRD < 0.01%4. For patients proceeding to HSCT, the recommended duration of treatment with BESPONSA is 2 cycles. A third cycle may be considered for patients who do not achieve CR/CRi and MRD negativity after 2 cycles5.

CR, complete remission; CRi, complete remission with incomplete haematological recovery of peripheral blood counts; InO, inotuzumab ozogamicin; ITT, intention-to-treat; MRD, minimal residual disease; SC, standard chemotherapy

Bridging patients to transplant​​​​​​​

INO-VATE: More BESPONSA-treated patients proceeded to transplant than with standard chemotherapy2

CI, confidence interval; HSCT, haematopoietic stem cell transplantation
