ABSTRACT

Aim. To analyze adverse cardiovascular events in chronic myeloid leukemia (CML) patients who received various tyrosine kinase inhibitors (TKI).

Materials & Methods. The trial included 97 CML patients with nilotinib, dasatinib or imatinib indications. By the time of examination the patients had undergone TKI therapy for 1–138 months. The three of them were sequentially treated with 2 drugs over the monitoring period. All CML patients were aged 22–79 years (median 53.5 years): 55 women were aged 22–71 years (median 53.5 years) and 42 men were aged 24–79 years (median 53 years).

Results. The comparative analysis demonstrated significantly higher impact of nilotinib on QTc duration compared with other TKIs. The patients who received nilotinib (n = 15) throughout 38 months had QTc of 0.47 s (interquartile range [IQR] 0.46–0.47 s), in imatinib group (n = 17) QTc was 0.43 s (IQR 0.43–0.44 s), and in dasatinib group (n = 4) QTc was 0.43 s (IQR 0.42–0.44 s) (p = 0.0008). Among all patients treated with nilotinib there were 62 % (31/50) with QTc > 0.46 s, in imatinib (6/41) and dasatinib (2/18) groups it was detected in 14.6 % and 11.1 % of patients, respectively (p = 0.0008). Five patients had QTc > 0.48 s, which is the criterion for discontinuation of treatment or dose reduction. In two patients the identified changes of QTc duration required TKI temporary suspension. After nilotinib dose reduction or discontinuation QTc duration normalized in all cases within 2 weeks. Decreased ankle-brachial index (ABI) < 0.9 without pronounced clinical symptoms was identified in two patients who received nilotinib. Afterwards they showed peripheral occlusive disease of lower extremities, and nilotinib treatment was discontinued. In patients treated with other TKIs no occlusive vascular lesions were observed. A case of chronic heart failure with reduced left ventricular ejection fraction developing on nilotinib therapy was revealed and described.

Conclusion. Despite high specificity for BCR-ABL tyrosine kinase, new TKIs can, although rarely, induce cardiovascular adverse events. Prior to TKI treatment assignment CML patients should be examined with ECG and EchoCG with systolic function evaluation, and the measurement of pulmonary artery pressure as well as ABI. The examination should be repeated in the end of the 1st year TKI treatment if there is no reason for extra examinations. It is recommended to hold 24-hour ECG monitoring with QTc max measurement prior to nilotinib assignment, then once a year within 2 years of nilotinib treatment, and once in 6 months after 3 years of therapy.

Keywords: imatinib, dasatinib, nilotinib, chronic myeloid leukemia, QTc prolongation, sudden cardiac death, peripheral occlusive disease of lower extremities, chronic heart failure, cardiomyopathy, pulmonary arterial hypertension.

ABSTRACT

Background. The tyrosine kinase inhibitors (TKI) era is marked by a long-term favorable prognosis of chronic myeloid leukemia (CML). In this context CML patients of reproductive age are faced with major issues of family planning with due regard to the risk of TKI treatment interruption during pregnancy. Additionally, TKI impact is another potential risk to the fetus.

Aim. To develop differentiated approach to CML treatment during pregnancy.

Materials & Methods. Analysis includes literature data and clinical experience based on 166 pregnancies of 120 CML patients from CML Pregnancy Registry.

Results. Pregnancy planning is recommended after achieving stable and deep molecular response (with BCR-ABL > 0.01 %, IS) within the period of at least 2 years. At conception TKI therapy does not have to be interrupted. However, early pregnancy detection and TKI treatment interruption after pregnancy confirmation are of vital importance due to teratogenic risks. Furthermore, no TKI may be administered during organogenetic period, i.e. up to the 15th week of gestation. In the absence or loss of complete hematologic response and growth of BCR-ABL > 1 % after the 15th week of gestation imatinib or nilotinib administration is justified in the interest of pregnant patients taking into account limited transfer of these drugs through placenta. In the absence of complete hematologic response before the 15th week of gestation interferon-α can be administered. With BCR-ABL < 1 % patients can be either followed-up without therapy or they can receive interferon-α throughout pregnancy. Dasatinib, bosutinib, and other TKI are contraindicated at any stage of pregnancy. There are no special recommendations for childbirth, delivery is to be adapted to obstetric conditions. Breast feeding is not recommended because of the lack of practical evidence for its safety.

Conclusion. A regular molecular monitoring of BCR-ABL and hematologic status is indispensable, health condition of fetus should be continuously monitored as well. CML patient management should be conducted by cooperating hematologists and gynecologists.

ABSTRACT

Background & Aims. The article presents results of two observational, prospective, multicenter studies “Quality of Life, Symptom Profile, and Adherence to Treatment in Adult Patients with Newly Diagnosed Chronic Phase Chronic Myeloid Leukemia Receiving Dasatinib” (2012–2015) and “Quality of Life and Symptom Profile in Imatinib-Resistant or Intolerant Patients with Chronic Myeloid Leukemia” (2011–2014).

Methods. Data of 107 patients with chronic myeloid leukemia in chronic phase were involved in the real-world analysis — 32 newly diagnosed patients on first-line treatment with dasatinib or after yearly switch to dasatinib after imatinib treatment failure and 75 imatinib-resistant or intolerant patients on second-line treatment with dasatinib. Treatment effectiveness and safety of dasatinib were assessed during first and second-line dasatinib treatment using clinical outcomes as well as quality of life and symptom profile assessment.

Results. The real-world data obtained during observational study in limited population of CML patients conform the results of clinical trials devoted to evaluation of treatment efficacy and safety of dasatinib treatment in first and second-line treatment and demonstrate the importance of patient-reported outcomes. Patient’s quality of life improved within 12 months of the first-line dasatinib therapy according to the following scales: role physical functioning, pain, vitality, social functioning and role emotional functioning. The most pronounced and clinically significant improvement was observed for the role emotional functioning (51.1 vs. 68.9). During the second-line dasatinib treatment, stabilization of quality of life parameters was registered for the following scales: vitality, social functioning, mental health, and pain. Significant improvement of the Integral Quality of Life Index was observed (p < 0.05). Positive dynamics of relevant symptoms was registered. The symptom severity decreased during both the first and second-line therapy.

Conclusion. Quality of life and symptom assessment in CML patients contribute to a better disease control in accordance with the principles of risk-adaptive therapy.

Keywords: quality of life, chronic myeloid leukemia, dasatinib, therapy effectiveness, therapy safety, routine clinical practice.

ABSTRACT

Background & Aims. Interpretation of key aspects of pathogenesis of chronic myeloid leukemia (CML) and development and introduction of target therapy have changed the prognosis of this once fatal disease dramatically. Results of numerous clinical trials demonstrated substantial superiority of tyrosine kinase inhibitors over previous therapy techniques. At the same time, clinical trials had limitations in patient enrollment, as well as treatment conditions and duration. The analysis of our clinical experience in CML target therapy (over the period from 2003 till 2015) is an important argument for introduction of novel drugs into routine clinical practice. The aim of the study is to analyze our own experience in CML target therapy and to compare our results with clinical trials data.

Methods. Outpatient’s cards and case histories of CML patients treated in the Russian Scientific Research Institute of Hematology and Transfusiology over last 12 years were analyzed in this work. Published results of multi-center clinical trials evaluating the use of tyrosine kinase inhibitors in CML were used for a comparative analysis. The primary morbidity rate and the prevalence of CML, results of first and subsequent treatment lines were studied with assessment of survival rates, adverse events, and the nature of the response (hematologic, cytogenetic and molecular).

Results. The experience in treatment of 208 CML patients was analyzed. The use of imatinib led to clinical and hematological remission (complete hematologic response) was achieved in 95 % of patients. The frequency of complete cytogenetic responses (CCyR) was 69 %, and that of major molecular responses (MMR) was 58 %. The overall 5-year survival (OS) was 86.4 %, the 10-years OS was 67.5 %. The use of nilotinib during the second line permitted to achieve CCyR in 61 % of patients, and the MMR in 55 % of cases. The two-year OS was 96 % and the 5-year OS was 68 %. CCyR and MMR were achieved in 50 % patients treated with dasatinib during the second line. As for the third line, CCyR was achieved in 50 % of patients and MMR in 25 %. In case of previous imatinib and nilotinib resistance, CCyR was observed only in 36 % of patients and MMR in 18 % of cases. During second-line dasatinib treatment, the 2-year OS was 85 %, and the 5-year OS was 51 %; as for the third line, the results were 75 % and 50 %, respectively. The range and rates of adverse events of the therapy, in general, corresponded to results of clinical trials.

Conclusion. The use of tyrosine kinase inhibitors in treatment of CML permits to prolong patient’s life span and quality of life significantly. The use of nilotinib and dazatinib (in case of nilotinib intolerance and/or resistance) could be effective in most patients.

Keywords: chronic myeloid leukemia, target therapy, tyrosine kinase inhibitors, imatinib, nilotinib, dasatinib, clinical practice.

ABSTRACT

Background. Second generation tyrosine kinase inhibitors (nilotinib and dasatinib) have advantages over imatinib in frequency and rate of cytogenetic and molecular responses obtaining in chronic myelogenous leukemia (CML) treatment. At the same time, they produced more severe adverse effects and are more expensive than imatinib. At present, CML patients with stable deep molecular response are considered as candidates for enrollment into clinical trials studying the management of treatment-free remission. Constant growth of expenses for CML diagnosing and treatment require a pharmacoeconomic analysis in order to optimize expenses and provide cost-effectiveness data for introduction of novel highly effective drugs.

Objective. Pharmacoeconomic modeling of the choice of CML treatment using first and second generation tyrosine kinase inhibitors in first-line therapy with an analysis of sensitivity of clinico-economic factors.

Methods. Pharmacoeconomic modeling of CML diagnosing and treatment. Cost-utility analysis of first and second generation tyrosine kinase inhibitors in first-line treatment. Sensitivity analysis with identification of most important clinical and economic factors affecting treatment results. Simulation for feasibility analysis of the nationwide use of first and second generation tyrosine kinase inhibitors in first-line therapy.

Results. Sensitivity analyses of pharmacoeconomic models showed its robustness. The threshold limits for drug costs and frequency of achievement of a complete molecular response affecting economic feasibility of the choice of first and second generation tyrosine kinase inhibitors were determined.

Conclusions. These pharmacoeconomic models may be applied for improvement of diagnostic and therapeutic standards.

Keywords: chronic myeloleukemia, tyrosine kinase inhibitors, imatinib, nilotinib, dasatinib, pharmacoeconomics, cost-effectiveness.

ABSTRACT

This review focuses on association between the selectivity of Bcr-Abl kinase inhibitors and the spectrum of their adverse effects during treatment of patients with chronic myeloid leukemia. The data on the structure and natural biochemical functions of the well-known adverse targets for inhibitors of Bcr-Abl kinases, including BRAF, FMS, EGFR, PDGFR, PYK2, TIE2, and VEGFR1/2/3 are summarized, and the potential association between their off-target inhibition and adverse effects of tyrosine-kinase inhibitors is suggested.

Keywords: chronic myeloid leukemia, tyrosine-kinase inhibitors, selectivity, imatinib, nilotinib, dasatinib, ponatinib, PF-114, BRAF, FMS, EGFR, PDGFR, PYK2, TIE2, VEGFR1/2/3.

ABSTRACT

The article is focused on preliminary results of the observational study “Quality of life and symptom profile in imatinib-resistant or intolerant patients with chronic myeloid leukemia during disease-modifying treatment” (2011–2012). 56 imatinib-resistant or intolerant patients with chronic myeloid leukemia in chronic phase were included in the preliminary analysis. It was shown that prior to treatment with dasatinib more than one third of patients had severe or critical quality of life deterioration. Patients treated with standard doses of imatinib during the first-line treatment reported better quality of life than patients treated with high doses of imatinib. After 12 months of treatment with dasatinib, the majority of patients showed complete or partial cytogenetic response (62 %); most of the patients with complete cytogenetic response were treated with standard doses of imatinib during the first-line treatment (19 % vs 8 %). During treatment with dasatinib, stabilization of quality of life parameters was recorded with a slight trend towards improved vitality, mental health, and pain scales. In the majority of patients (68 %), the treatment response as improved or stabilized quality of life was observed. During treatment with dasatinib, severity of the most frequent disease- or treatment-specific symptoms decreased. In this observational study, it was shown that dasatinib therapy in the real-world practice is effective both in terms of clinical parameters and patient-reported outcomes, and characterized by good tolerability.

Keywords: quality of life, symptom profile, chronic myeloid leukemia, dasatinib.
