Abstract Background Oral BCR-ABL tyrosine kinase inhibitors (TKIs), including imatinib (IM), dasatinib (DAS) and nilotinib (NIL), have improved survival in chronic-phase chronic myeloid leukemia (CP-CML). Few data are available that compare TKIs in daily clinical practice across multiple regions. Methods SIMPLICITY is an ongoing observational cohort study of adult patients with newly diagnosed CP-CML receiving first-line treatment with IM, DAS or NIL in the USA and Europe (Eu) outside of clinical trials (NCT01244750). The primary objective is to assess effectiveness of these TKIs in clinical practice. The study includes three ‘prospective’ cohorts of patients treated with IM, DAS or NIL since 2010 (the study opened after first-line approval of all three TKIs) and a ‘historical’ cohort treated with IM since 2008. Preliminary baseline demographics are presented for prospective cohorts. Results 860 prospective patients (Eu: 32%, USA: 68%) were enrolled through June 20, 2013, receiving IM (n=399), DAS (n=229) or NIL (n=232). Median age at initiation of first-line TKI was 56 years, with significant differences in pairwise comparisons between DAS and IM and NIL and IM (Table). Demographics were consistent across cohorts. Only 30% of patients had Hasford or Sokal scores recorded. ECOG performance status (PS) was available in 54% of patients. The number of baseline comorbidities per patient (mean: 3.2 + 2.7) was balanced across cohorts; 51% of patients presented with ≥3 comorbidities. Patients in the IM cohort had a higher prevalence of gastrointestinal comorbidities (P=.006 and .007 for DAS vs IM and NIL vs IM, respectively), and the NIL cohort had a higher prevalence of musculoskeletal comorbidities than the DAS cohort (P=.015). The proportions of patients with cardiovascular comorbidities were 38%, 36% and 42% in the DAS, NIL and IM cohorts, respectively, consisting primarily of hypertension (31%) and hyperlipidemia (17%) (P>.05 across cohorts). Coronary artery disease was present in 9%, cardiac arrhythmias in 6%, myocardial infarction in 3% and peripheral arterial disease in 2% of patients. The proportion of patients with diabetes was 10%. Clinicians reported effectiveness as the most common reason for TKI selection; familiarity and cost were also cited as reasons for IM selection (P<.001 vs DAS and NIL). Comorbidities were not drivers of TKI selection in this analysis. Conclusions This is the first report from the prospective cohorts of SIMPLICITY. Demographics were consistent across cohorts. Overall, the SIMPLICITY population is older with potentially more comorbidities than patients enrolled in first-line clinical trials with restrictive inclusion criteria (NEJM 2003 348 994; NEJM 2010 362 2260; NEJM 2010 362 2251). Initial TKI selection does not appear to be driven by baseline comorbidity, rather by perceived effectiveness, cost and familiarity. Hasford/Sokal scores were not recorded in the majority of patients prior to starting first-line TKI therapy. Outcomes data are being collected across cohorts that will inform about a multi-region population treated outside clinical trials.

Abstract Introduction: in the last 10 years the number of tyrosine kinase inhibitors (TKI) used to treat patients with chronic myeloid leukemia (CML) significantly increased. The basic principle of therapy was also changed, now it is aimed at early induction of deep response (ELN, NCCN). The treatment results in clinical practice may vary widely and depend on the effectiveness of the entire complex TKI, based on timely evaluation of residual leukemic clone. Objective: To characterize the TKI treatment results and monitoring of residual leukemic clone in clinical practice in CML patients in the Russian Federation (RF). Methods: The observational study "Russian registry of chronic myeloid leukemia management in routine clinical practice" (CSTI571ARU06 LLC) was launched in November 2011 by Novartis. Patients with Ph'+ CML were enrolled into study after signing the informed consent. Thus the study has a retrospective part (4626 patients) and prospective group of 1828 CML patients. By February 2015, the Registry contained information about 6466 patients from 110 centers of 80 regions of the RF. The annual increase of newly registered CML cases ranged from 493 to 694 people per year or 10-13% of the total number of patients included in the Registry on the treatment of CML in 2012- 2014. Characteristics of patients in the Registry: median duration of the disease was 71 months (from 0.2 to 343 months); median age at registration time and CML diagnosis was 49.5 years (range 2 - 94 years); male 43%. The biggest number of cases was diagnosing with patients aged 50-69 years old, which is 50% out of all the registered patients. It is important to note that the number of female patients aged 50 years old and older (39.1% in total, out of the overall number of CML cases) prevails the same male patients age group (25.6% of the cases). Chronic phase was in 93.6% of patients, accelerated phase and blast crisis- 5.6% and 0.6% cases, accordantly. Sokal risk group's ratio was 50%/31%/19% for low, intermediate and high risk, respectively. Results: The data for the analysis were available for 5632 patients (93% of CML patients in the Registry). The 1st line TKI therapy was Imatinib (IM)- in 4908 of the 5632 patients (87%), including the advanced phases of CML; in 71 and 14 patients the 1st line treatment was nilotinib and dasatinib respectively(totally 1%). The percentage of patients receiving TKI-2 ranged from 10 to 35% in different regions of RF. In 2006, the diagnosis CML was confirmed by the data of karyological analysis only with 42% of the patients, but it should be pointed out that currently cytogenetic and/or molecular-based analysis has been conducted at least once with 99% of the patients. Thus, the data presented in Registry of CML treatment provides grounds to state that almost all the patients have had their diagnosis verified within routine clinical practice. The presented data demonstrate the amount of work done to obtain such results during the previous ten-year period. We evaluated cytogenetic monitoring (CyM)/molecular monitoring (MM) frequency during years 2013-2014. Two or more studies per year of cytogenetic CyM/MM were done only 20% of 40 patients per year (2320 persons); with 50% (2960 in 2013, 1203 in 2014) of patients CyM/MM was performed once; no studies have been done in 489 patients in 2013 and 3580 patients in 2014. There was a trend of increasing of molecular studies to evaluate minimal residual disease:1829 MM vs 491 CyM in 2013 and 1028 MM vs 179 CyM in 2014. The absence of optimal response (ELN2013) was observed in 887 patients on different TKIs: (759patients on IM: in 732 patients with the duration of IM therapy over 12months and in 27 patients-less than 12months. Change of treatment to 2nd line was performed in 639 (12%) patients. The death occurred in 373 (6.2%) patients, no data of the living status was in 50 (0.8%) cases. According to the Registry data, death due to the CML progression was in 99 cases (26%). Conclusions: The observational study "Russian registry of chronic myeloid leukemia management in routine clinical practice" is the largest registry of hematological diseases in Russia, providing information about CML patients receiving TKI therapy more than 10 years. The introduction of information technologies to analyze a large amount of data is an essential component to improve the quality of medical care. The evaluation of therapy results can give objective information of the TKI 1st and 2nd generations requirement.

Safety And Efficacy

Background: Nilotinib, a second-generation tyrosine kinase inhibitor (TKI), is approved for the treatment of patients with chronic myeloid leukemia (CML) in many countries, including Taiwan. Though a number of controlled clinical trials have demonstrated the safety and efficacy of nilotinib, studies assessing the safety and efficacy of nilotinib in routine clinical practice are limited. Methods: The current study was an open-label, single-arm study conducted across 12 centers in Taiwan in adult patients with CML in chronic or accelerated phase with confirmed Ph+ chromosome (or BCR-ABL) and resistant or intolerant to one or more previous TKIs. The primary objective was to collect the long-term safety data in patients treated with nilotinib 400 mg, twice daily for up to 2 years. Results: The study enrolled 85 patients with CML, including 76 in the chronic phase (CML-CP) and 9 in the accelerated phase (CML-AP). Overall, 1166 adverse events (AEs) were reported in 80 patients (94.1%), of which 70 AEs (6%) in 28 patients (32.9%) were serious and 336 AEs (28.8%) reported in 60 patients (70.6%) were drug-related. Common drug-related AEs were thrombocytopenia (21.2%), increased alanine aminotransferase (21.2%) and pruritus (17.7%). Of the 85 patients, 19 switched from imatinib due to intolerance – AEs were resolved in 16 of these 19 patients (84.2%). By 24 months, the cumulative rates of complete cytogenetic response (CCyR), major molecular response (MMR), MR4.0 ( BCR-ABL1IS ⩽0.01%) and MR4.5 ( BCR-ABL1IS ⩽0.0032%) were 75.3, 56.8, 16.2 and 7.4%, respectively. Patients with CML-CP at baseline had higher overall survival (OS) and progression-free survival (PFS) than those with CML-AP. Conclusion: This is the first study that demonstrated that nilotinib is effective and well-tolerated in patients resistant or intolerant to imatinib in the real-world setting in Taiwan, reflecting effective management of CML by physicians under routine clinical practice in Taiwan.

Abstract Introduction: The combined effect of cardiovascular (CV) risk and tyrosine kinase inhibitor (TKI) therapy may contribute to the incidence of CV events in patients (pts) with chronic phase chronic myeloid leukemia (CP-CML). CV events can affect the overall clinical outcomes and survival of CML patients, and hospitalization due to CV events is costly; analyzing the rates and risks of CV hospitalization in pts with CML receiving TKI therapy may help to inform treatment decisions and risk mitigation strategies and to minimize costs. SIMPLICITY (NCT01244750) is an ongoing observational study of CP-CML pts in routine clinical practice receiving first-line (1L) TKIs since 2010 in the US and Europe, exploring TKI use and management patterns in clinical practice. This analysis aims to evaluate rates of CV-related hospitalization and estimate related costs in pts treated with the second-generation TKIs dasatinib (DAS) and nilotinib (NIL). Methods: CV hospitalizations were identified retrospectively from events reported by SIMPLICITY investigators over the course of treatment with DAS or NIL, from the start of treatment (any line of therapy) to 30 days after the end of that line of therapy, or prior to the start of a subsequent line of TKI therapy, whichever was sooner. Pts were followed for a maximum of five years. Owing to the observational nature of SIMPLICITY, patients were not matched between cohorts and adjustments for covariates were not made. Kaplan-Meier methods with the log-rank test were used to estimate time to first CV hospitalization. Statistical comparisons were made using t-tests and the Mann-Whitney U test for continuous variables and chi square for categorical variables. Results: Overall, 825 pts received DAS (n=417) or NIL (n=408) as 1L therapy; 376 pts received DAS (n=214) or NIL (n=162) as second-line (2L) therapy; and 124 pts received DAS (n=63) or NIL (n=61) as third-line (3L) therapy. See table for patient baseline demographics and comorbidities. No significant differences were noted between the DAS and NIL cohorts. Median age was similar between the DAS and NIL groups at 56.2 and 54.1 years. At baseline, both groups had similar CV comorbidities. A significantly greater number of pts were treated in the US vs Europe (p=0.017). Investigators reported that, during 1L DAS and NIL therapy, 43% (n=357) of pts experienced a CV disorder: 45.3% (n=189) of DAS pts and 41.2% (n=168) of NIL pts (DAS vs NIL, p=0.28). Numbers of CV-related hospitalizations occurring during DAS and NIL therapy were 16 and 36, respectively, translating to 12.6 and 27.4 CV-related hospitalizations per 1000 pt years. Across 1L, 2L, and 3L (referred to here as 'all lines') of DAS and NIL therapy, 31 and 51 CV-related hospitalizations occurred, translating to 16.7 and 28.8 CV-related hospitalizations per 1000 pt years, respectively. The three most common CV-related reasons for hospitalization were congestive cardiac failure, atrial fibrillation and myocardial infarction. The figure shows Kaplan-Meier curves of time to first CV-related hospitalization for 1L therapy, for five years of follow-up. CV-related hospitalization at 5 years of follow-up was 5% for pts on 1L DAS, 7.5% for pts on 1L NIL, 5.7% for all lines of DAS and 8.5% for all lines of NIL. Durations of hospital stay related to CV disorders for pts on 1L DAS and 1L NIL were 68 days and 263 days, translating to 53.3 and 199.8 days in hospital per 1000 pt years. Durations of hospital stay related to CV disorders for pts on all lines of DAS and NIL were 107.4 days and 226.1 days, translating to 53.3 and 199.8 days in hospital per 1000 pt years. Incremental cost differences based on mean estimates will be presented. Conclusions: CV disorders and related hospitalizations were frequently seen in patients with CP-CML in SIMPLICITY. In these patients, NIL was associated with a rate of CV hospitalization up to double that associated with DAS and lengthier hospital stay. Owing to the survival benefits conferred by TKIs, it is critical to minimize and manage complications that may arise in treated pts; potential for greater morbidity and healthcare cost should be considered when making decisions about TKIs to use in individual pts, particularly those with preexisting CV comorbidities.
