ABSTRACT

Aim. To assess the efficacy, safety, and tolerance of gemtuzumab ozogamicin (GO) combined with FLAG/FLAG-Ida chemotherapy or azacitidine in patients with relapsed/refractory acute myeloblastic leukemia (AML) in clinical practice.

Materials & Methods. The study included 32 patients (16 men and 16 women). The median age was 44 years (range 23–83 years). Among them there were 15 (46.8 %) patients with refractory and 17 (53.2 %) patients with relapsed AML. GO combined with FLAG/FLAG-Ida was administered to 15 (46.8 %) patients, whereas 17 (53.2 %) patients were treated with GO and azacitidine combination. Therapy safety was assessed according to CTCAE v. 5.0.

Results. Overall response rate including complete remission (CR), CR MRD–, CR with incomplete hematologic recovery, and morphologic leukemia-free status was 59.4 % (19/32). Refractoriness was observed in 31.25 % (10/32) of patients. Early mortality was 9.4 % (3/32). Overall response was 64.7 % (11/17) in the azacitidine and 53.3 % (8/15) in the FLAG/FLAG-Ida groups. In 4 (80 %) out of 5 patients with prior to FLAG treatment refractoriness, the response was achieved after GO + azacitidine therapy. In 58.9 % (10/17) of patients who received GO + azacitidine therapy, allogeneic hematopoietic stem cell transplantation (allo-HSCT) could be performed. The incidence of GO infusion complications in the tested groups did not significantly differ (= 0.72) and was 46.7 % (7/15) (40 % with grade 1/2 and 6.7 % with grade 3) in the GO + FLAG/FLAG-Ida group and 35.3 % (6/17) (29.4 % with grade 1/2 and 5.9 % with grade 4) in the GO + azacitidine group. In the GO + FLAG/FLAG-Ida group 5 (33.3 %) patients experienced serious adverse events (SAE) of sepsis. In the GO + azacitidine group SAEs were reported in 6 (35.3 %) patients: 4 (66.6 %) with sepsis, 1 (16.7 %) with acute cardiovascular failure, and 1 (16.7 %) with acute respiratory failure. The median (range) duration was 23 (10–39) days for neutropenia grade 4, 24 (11–38) days for neutropenia grade 3, 21 (11–41) days for thrombocytopenia grade 4, 26 (16–45) days for thrombocytopenia grade 3, and 25 (22–45) days for thrombocytopenia grade 1/2. Thrombocytopenia duration was longer in patients with GO + FLAG/FLAG-Ida therapy, however, no significant differences were identified. No cases of veno-occlusive liver disease were reported. Median overall survival (OS) for both groups (n = 32) was 31.4 months, median disease-free survival (n = 21) was 13.3 months. In the group of patients with effective treatment, the median OS was not reached. In non-responders, it was 18 months (= 0.0442).

Conclusion. GO combined with FLAG/FLAG-Ida chemotherapy or azacitidine proved effective in relapsed/refractory AML patients. Remission did not appear to be associated with ELN risk, gender, age, CD33 expression, number of prior therapy lines, or number of relapses. GO + azacitidine combination showed efficacy, safety, and good tolerance in patients with prior high-dose chemotherapy refractoriness as well as low ECOG performance status. That allowed for the subsequent allo-HSCT administration to these patients. There was no significant difference between the groups of patients in the incidence of hematologic, non-hematologic toxicity, and time to hematologic recovery. Thrombocytopenia duration was longer in patients with GO + FLAG/FLAG-Ida therapy which is consistent with literature data. GO-based effective treatment in relapsed/refractory AML considerably improves OS: during 36 months of follow-up the median was not reached.

ABSTRACT

Background. Haploidentical bone marrow transplantation (BMT) can be a reliable alternative if a fully matched donor is not available. The main challenges after BMT are a relapse of major disease, graft-versus-host disease (GVHD), and infections. Azacitidine possesses antileukemic effect together with immunomodulating properties and being administered soon after BMT can significantly improve the outcome.

Aim. To study azacitidine effect on the outcome of haploidentical BMT in patients with acute myeloid leukemia (AML) in the early post-transplantation period.

Materials & Methods. The trial included 18 AML patients who received haploidentical BMT at VA Almazov National Medical Research Center. In all patients MRD-negative remission was achieved on the 30th day after BMT. Azacitidine therapy was initiated not earlier than 2 months after BMT with a complete engraftment of transplant and no GVHD. Azacitidine 100 mg/day was administered on D1–D5 every 28 days within a year after BMT. When a molecular relapse was detected, donor lymphocytes were additionally infused during every other cycle of therapy.

Results. Eleven patients received preventive azacitidine treatment, 7 patients were included in control group. Median onset of azacitidine treatment after haploidentical BMT was 4 months (range 2–10 months), median number of azacitidine courses was 3.5 (range 1–9). During azacitidine treatment acute GVHD was identified in 5 (45.4 %) patients. In 4 of them an exacerbation of earlier GVHD was detected (3 with cutaneous form and 1 with intestinal form), and only in 1 patient de novo acute intestinal GVHD was discovered.

Conclusion. Azacitidine treatment of AML patients after haploidentical allo-BMT is safe and well tolerated. Preventive azacitidine treatment after haploidentical BMT improves overall survival of AML patients.

ABSTRACT

Background & Aims. The aim of the study was to evaluate the efficacy and safety of azacytidine and decitabine prior to allogeneic hematopoietic stem cell transplantation (allo-HSCT) in acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), chronic myelomonocytic leukemia and juvenile myelomonocytic leukemia.

Materials & Methods. The research included 62 patients who received hypomethylating agents (HMA) prior to allo-HSCT. The median age was 28 years (range from 1 to 68 years), the study population consisted of 27 (43.5 %) women and 35 (56.5 %) men.

Results. The overall response (complete + partial remission) was observed in 42 % (n = 26) of cases. At the time of allo-HSCT no disease progression was observed in 41 (66 %) patients. The multivariant analysis showed the overall survival (OS) statistically significantly increased with the graft retention (hazard ratio [HR] 0.002; 95% confidence interval [95% CI] 0.001–0.74; p = 0.03), and also with the administration of HMA after allo-HSCT (HR 0.24; 95% CI 0.08–0.67; p = 0.007). The response (stabilisation, partial or complete remission) due to HMA administration prior to allo-HSCT (HR 6.4; 95% CI 0.75–54.0; p = 0.08) was associated with improved OS. The event-free survival (EFS) was significantly higher with the response to azacytidine and decitabine at the time of allo-HSCT (HR 38.9; 95% CI 1.3–1198.0; p = 0.03) and with the graft retention (HR 0.02; 95% CI 0.005–0.1; p = 0.001). In patients with MDS compared with AML (HR 2.3; 95% CI 0.9–22.0; p = 0.08), there was a tendency to EFS improvement. Progression-free survival rates were higher in patients with a number of blast cells in the bone marrow less than 31 % at the time of diagnosis (HR 1.1; 95% CI 1.1–9.9; p = 0.01).

Conclusion. The use of azacytidine and decitabine prior to allo-HSCT allows to safely control the tumor mass in patients with MDS and to maintain the achieved remission with AML. In patients with a response to HMA, the best OS and EFS values are seen after allo-HSCT.

ABSTRACT

Aim. To evaluate the effectiveness of preventive and prophylactic post-transplantation therapy using azacitidine (5-AZA) in patients at high risk of post-transplantation relapse.

Methods. 136 patients were included in the study performed by the pairwise comparison: 68 of them received 5-AZA after allo-HSCT and 68 patients were included in the historical control group. 5-AZA was prescribed for prophylactic or preventive purposes. The results were assessed according to the OS, RR, EFS, DUM, and relapse-free and GVHR-free survival.

Results. 1-year OS was 76 % in the 5-AZA group (95% CI 60–84 %) and 44 % in the reference group (95% CI 33–55 %) (= 0.001); 2-year OS was 63 % (95% CI 39–67 %) and 37 % (95% CI 26–48 %) (= 0.007), respectively. The relapse rate (RR) in the 5-AZA group was 34 % (95% CI 22–46 %) during 1 year and 51 % (95% CI 38–64 %) in the reference group (= 0.02). 1- and 2-year disease unrelated mortality (DUM) was similar: 5 % in the 5-AZA group (95% CI 0.1–14.0 %) and 25 % (95% CI 13–37 %) in the reference group (= 0.005). 1-year EFS was 76 % in the 5-AZA group (95% CI 61–85 %) and 44 % in the reference group (95% CI 33–55 %) (= 0.001); 2-year EFS was 63 % (95% CI 39–67 %) and 37 % (95% CI 26–48 %) (= 0.01), respectively. 1-year relapse-free and GVHR-free survival was 55 % in the 5-AZA group (95% CI 41–69 %) and 28 % in the reference group (95% CI 17–39 %) (= 0.001); 2-year relapse-free and GVHR-free survival was 47 % (95% CI 32–62 %) and 27 % (95% CI 17–37 %) (= 0.002), respectively.

Conclusion. The use of 5-AZA for prophylactic and preventive purposes after allo-HSCT does not increase the risk of GVHR and DUM, does not suppress the GVL effect and can be used in combination with the donor lymphocyte infusion (DLI). The therapy with 5-AZA is safe during the early period after allo-HSCT. The drug does not suppress the GVL effect and can be used in high risk patients to prevent early post-transplantation relapse. The use of 5-AZA in combination with DLI does not increase the incidence of severe GVHR.

ABSTRACT

The review describes epigenetic processes, including methylation of nuclear and mitochondrial DNA, as well as RNA. It dwells on mechanisms of demethylation and corresponding medicinal products. It presents detailed information on results of numerous large randomized studies intended to evaluate hypomethylating agents (azanucleosides). Special attention is paid to outcomes of azanucleoside therapy in patients with acute myeloid leukemias. The article describes several prognostic systems and treatment algorithms for myelodysplastic syndromes. Two azanucleosides have been approved in Russia to date: azacitidine (for SQ administration) and decitabine (for IV administration). International authors analyze the experience in oral and subcutaneous administration of decitabine. However, the problem of off-label use of hypomethylating agents is still open. The review gives a brief description of ongoing clinical trials with azanucleosides.


Keywords: epigenetics, acute myeloid leukemias, myelodysplastic syndromes, azacitidine, decitabine, hypomethylating agents, azanucleosides.

ABSTRACT

Aim. To evaluate types of response to azacitidine associated with improvement of overall survival (OS) rates of patients with acute myeloid leukemias (AML) and myelodysplastic syndromes (MDS).

Methods. A retrospective analyses of medical records of 14 AML patients and 13 MDS patients at the age of 39 to 84 treated with azacitidine at a dose of 75 mg/m2 subcutaneously for 7 subsequent days every 28 days was performed. The therapy effectiveness was evaluated according to modified 2006 IWG criteria. The OS was calculated beginning with the date of initiation of the azacitidine therapy.

Results. From 2 to 25 azacitidine cycles was performed. Complete remission (CR) was achieved in 6 patients (22.2 %) including 4 AML and 2 MDS patients. Bone marrow remission (mCR) was diagnosed in 1 MDS patient (3.7 %). Hematological improvement was obtained in 11 patients (40.7 %) including 5 AML and 6 MDS patients. The overall response was 66.7 % (18 to 27 patients). There was no correlation between the therapy effectiveness and patients’ age, disease type, duration of the previous period, baseline hemoglobin, leukocytes, and platelets levels, and dependence on transfusions of erythrocyte suspension and thromboconcentrate. The therapy was considered ineffective in 9 patients (33.3 %). Stabilization with retained requirements of blood component transfusion was observed in 4 AML and 3 MDS patients. 2 patients presented gradual increase of the blast cell count in the bone marrow. The follow-up period was 2–29 months. The median OS of all patients was 11.5 months. The median OS of patients with CR, mCR and hematological improvement was significantly greater than that in the group of patients with stable disease and progression: 15.9 versus 7.4 months, respectively (= 0,010).

Conclusion. Reduction of transfusion requirement and/or stable improvement of peripheral blood levels due to azacitidine administration are associated with improved OS rates of AML and MDS patients.
