Ph’+ acute lymphoblastic leukemia (Ph’+-ALL) is an oncohematologic disorder for which allogeneic bone marrow transplantation still offers the only chance of cure. However, relapse is the main reason for treatment failure, also after hematopoietic stem cell transplantation (HSCT). New drugs, such as third generation tyrosine kinase inhibitors (TKIs) and monoclonal antibodies, have expanded the therapeutic landscape, especially in patients who relapsed before HSCT. Very few reports, up to now, have described the use of both classes of these new agents in combination with donor lymphocyte infusions (DLI) in the setting of patients who relapsed after HSCT. We report on a young patient affected by Ph’+-ALL, who relapsed after the second HSCT and who reached molecular remission and long-term disease control by treatment with the anti-CD22 monoclonal antibody inotuzumab ozogamicin, DLI, and the 3rd generation TKI ponatinib.

6540 Background: Disease relapse is the major cause of failure after allogeneic hematopoietic stem cell transplantation (SCT) for acute lymphoblastic leukemia (ALL). Treatment options for these patients (pts) are limited and only a second SCT provides a realistic chance for long term disease remission. Methods: We retrospectively analyzed the outcomes of 31 pts with ALL who relapsed following their first allogeneic SCT, and went on to receive a second allogeneic SCT. Univariate analysis was used to assess for risk factors which influenced treatment-related mortality (TRM), and progression free survival (PFS) following second SCT. Results: 31 pts were evaluable for response with 2 early deaths within 30 days of SCT. The median age of the pts was 26 years (range 7- 49), and the median duration between their first SCT (SCT1) to relapse was 9.5 months (range 2.2-32.6 months). 39% of pts were transplanted in active disease (n=12). The complete remission (CR) rate post SCT was 89%; 83% of pts transplanted with active disease attained CR. With a median follow-up of 3 years among survivors, PFS, and OS rates at 1 year were estimated at 23%. The TRM rate was 41% at 12 months. We did not identify any factors that impacted TRM through univariate analysis. We found a significant relationship between the time to progression following SCT 1 and PFS following SCT 2 (p=0.02, HR=0.93/month). Conclusions: In summary, a second transplant remains an effective method for achieving response in a highly refractory patient population. Pts with longer PFS following SCT1 have a better PFS following SCT2. While long-term survival is limited, a significant proportion of pts remain disease-free for up to one year following SCT2, providing a window of time to administer preventive interventions. Notably, our 4 long-term survivors, received novel therapies in the form of a single umbilical cord blood unit in addition to the PBSC to augment the immune response (n=2), a change in the stem cell source for the SCT from cord to mismatched adult unrelated (n=1), and post SCT maintenance therapy with 5-azacytidine (n=1), underscoring the need for a fundamental change with the methods for the second transplant to improve outcome.

Background: The prognosis of refractory/relapsed B-cell precursor acute lymphoblastic leukemia (BCP-ALL) remains dismal owing to acquired resistance to chemotherapeutic agents. This study aimed to evaluate the efficacy of T-cell replete HLA haploidentical hematopoietic stem cell transplantation (TCR-haplo-HSCT) for pediatric refractory/relapsed BCP-ALL (RR-BCP-ALL).Methods: Nineteen pediatric patients with RR-BCP-ALL underwent TCR-haplo-HSCT between 2010 and 2019 at the Fukushima Medical University Hospital. The disease status at TCR-haplo-HSCT included complete remission (CR) in eight patients and non-CR with active disease in 11 patients. Total body irradiation-based, busulfan-based, and reduced-intensity conditioning regimens were employed in 11, 6, and 2 patients, respectively. Low-dose anti-thymocyte globulin (thymoglobulin, 2.5 mg/kg) was used in all patients. Graft-vs.-host disease (GVHD) prophylaxis was administered with tacrolimus, methotrexate, and prednisolone.Results: All patients received peripheral blood stem cells as the stem cell source. The HLA disparities in graft vs. host directions were 2/8 in one, 3/8 in five, and 4/8 in 13 patients. Among 18 patients who achieved primary engraftment, acute GVHD occurred in all 18 evaluable patients (grade II, 9; grade III, 8; grade IV, 1), and chronic GVHD was observed in 10 out of 15 evaluable patients. Three patients died because of transplant-related mortality. The 3-year overall survival (OS) and leukemia-free survival rates were 57.4 and 42.1%, respectively. Compared to patients older than 10 years in age (N = 10), those younger than 10 years in age (N = 9) showed an excellent OS rate (3-year OS rate: patients < 10 years old, 100%; patients > 10 years old, 20% [95% confidence interval, 3.1–47.5]; p = 0.002).Conclusions: We suggest that TCR haplo-HSCT with low-dose ATG conditioning has the potential to improve the transplantation outcomes in patients with RR-BCP.
