Abstract
This study investigated changes in treatment modalities and outcomes of chronic myeloid leukemia in the chronic phase (CP-CML) after the approval of second-generation tyrosine kinase inhibitors (2G-TKIs) for first-line therapy. Patients were grouped into those who underwent TKI therapy up to December 2010 (imatinib era group, n = 185) and after January 2011 (2G-TKI era group, n = 425). All patients in the imatinib era group were initially treated with imatinib, whereas patients in the 2G-TKI era group were mostly treated with dasatinib (55%) or nilotinib (36%). However, outcomes including progression-free survival, overall survival, and CML-related death (CRD) did not differ significantly between groups. When stratified by risk scores, the prognostic performance of the ELTS score was superior to that of the Sokal score. Even though both scoring systems predicted CRD in the imatinib era, only the ELTS score predicted CRD in the 2G-TKI era. Notably, the outcome of patients classified as high-risk by ELTS score was more favorable in the 2G-TKI era group than in the imatinib era group. Thus, expanding treatment options may have improved patient outcomes in CP-CML, particularly in patients classified as high-risk by ELTS score.

Abstract
Most clonal cytogenetic abnormalities of Philadelphia-negative cells (CCA/Ph-) occurring during tyrosine kinase inhibitor (TKI) treatment are transient, and the development of secondary myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML) is rare, but the frequency and clinical significance in Japanese patients are still unknown. We herein report four patients who developed CCA/Ph- during TKI therapy and were diagnosed with secondary MDS/AML. The duration from TKI therapy initiation to MDS/AML onset ranged from 3 to 48 months, and the survival ranged from 5 to 84 months. The occurrence of CCA/Ph- with MDS/AML may be associated with a poor prognosis, and careful follow-up is recommended for patients who receive TKI therapy.

Cha SH, Kim K, Song YK. Comparison of cutaneous adverse events between second-generation tyrosine kinase inhibitors and imatinib for chronic myeloid leukemia: a systematic review and meta-analysis. Acta Oncol 2023; 62:1767-1774. [PMID: 37787749 DOI: 10.1080/0284186x.2023.2263152] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Accepted: 09/20/2023] [Indexed: 10/04/2023]
Abstract
BACKGROUND Patients with chronic myeloid leukemia (CML) treated with tyrosine kinase inhibitors (TKIs) often experience cutaneous adverse events, such as rashes and pruritus. In this study, we aimed to compare the risks of cutaneous adverse events between imatinib- and second-generation TKI-treated patients with CML. MATERIAL AND METHODS Paired reviewers independently obtained studies from PubMed, Embase, and Cochrane Library published until 15 March 2022. The following terms were searched: (Leukemia, Myelogenous, Chronic and BCR-ABL Positive), chronic myeloid leukemia, tyrosine kinase inhibitor, TKI, imatinib, dasatinib, nilotinib, bosutinib, and radotinib. Two independent reviewers screened the results and selected articles on cutaneous adverse events. RevMan 5.4 and the Cochrane Collaboration tool were used to perform the meta-analysis and risk of bias assessment. RESULTS AND CONCLUSION Eleven trials involving 4502 patients were analyzed in this study. Patients treated with second-generation TKIs were significantly more likely to experience cutaneous adverse events than those treated with imatinib with a relative risk (RR) of 1.62 (95% confidence interval [CI], [1.25-2.09]). Except dasatinib (RR [95% CI], 1.39 [0.75-2.56]), the risk of adverse events was more with second-generation TKIs than with imatinib as follows: nilotinib (2.11 [1.53-2.90]), bosutinib (1.41 [1.07-1.86]), and radotinib (1.87 [1.33-2.63]). Rash was the most common cutaneous adverse event that was observed in 21.6% of cases across all grades, followed by pruritus (5.7%) and alopecia (4.3%). In conclusion, our findings suggest that cutaneous adverse events occur more frequently with second-generation TKIs than with imatinib. Therefore, effective management of the cutaneous outcome is necessary to achieve high patient adherence to medication and successful treatment with TKIs.

Asciminib vs bosutinib in CML patients pretreated with ≥2 tyrosine kinase inhibitors: Results from the Japanese subgroup analysis of ASCEMBL study. Cancer Med 2022; 12:2990-2998. [PMID: 36168187 PMCID: PMC9939084 DOI: 10.1002/cam4.5212] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2022] [Revised: 06/01/2022] [Accepted: 08/24/2022] [Indexed: 11/10/2022] Open
Abstract
Asciminib, a first-in-class, allosteric inhibitor of BCR-ABL1 that acts by STAMP (Specifically Targeting the ABL Myristoyl Pocket), is a novel therapeutic option for patients with chronic myeloid leukemia (CML). In the global, phase 3, open-label ASCEMBL study in patients with CML in chronic phase (CML-CP) pretreated with ≥2 tyrosine kinase inhibitors (TKIs) (NCT03106779), asciminib (40 mg twice-daily) demonstrated significant superiority over the ATP-competitive TKI bosutinib (500 mg once daily) for the primary endpoint of major molecular response (MMR; BCR::ABL1 transcript levels on the international scale [BCR::ABL1IS ] ≤0.1%) at week 24. Here, we report results from a descriptive subgroup analysis of Japanese patients enrolled in ASCEMBL study (data cut-off: May 25, 2020). Overall, 16 Japanese patients were randomized (asciminib, n = 13; bosutinib, n = 3). At week 24, the MMR rate with asciminib was 30.8% (4/13; 95% confidence interval [CI], 9.09-61.43). BCR::ABL1IS ≤1% and complete cytogenic response (CCyR) at week 24 were 61.5% (8/13 patients) and 50.0% (4/8 patients), respectively. In the bosutinib group, no patient achieved MMR, CCyR, or BCR::ABL1IS ≤1%, but results were limited by the low number of patients. The safety profile of asciminib was comparable to that previously observed in the overall study population. Findings from this Japanese subgroup analysis of the ASCEMBL study support the use of asciminib for the treatment of Japanese patients with CML-CP previously treated with ≥2 TKIs.

Bosutinib in Japanese patients with newly diagnosed chronic-phase chronic myeloid leukemia: final 3-year follow-up results of a phase 2 study. Int J Hematol 2022; 116:871-882. [PMID: 35963986 PMCID: PMC9668794 DOI: 10.1007/s12185-022-03435-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2022] [Revised: 07/29/2022] [Accepted: 07/31/2022] [Indexed: 11/24/2022]
Abstract
Bosutinib has been evaluated for treatment of chronic-phase chronic myeloid leukemia (CP-CML) in several clinical studies, including in Japan. This open-label, single-arm, phase 2 study evaluated the efficacy and safety of bosutinib at a starting dose of 400 mg once daily in Japanese patients (n = 60) with newly diagnosed CP-CML. The minimum follow-up period was 3 years and median duration of treatment was 35.9 months. At study completion, 60% of patients were still on treatment. Cumulative rates of major molecular response (MMR), molecular response4 (MR4), and MR4.5 at any time were 70.0%, 53.3%, and 48.3%, respectively. No patient who achieved MMR or MR4 had a confirmed loss of response. No patient experienced on-treatment transformation to accelerated/blast phase or died within 28 days of the last bosutinib dose. Any-grade treatment-emergent adverse events (TEAEs) occurred in 100% (grade ≥ 3: 81.7%) of patients. The most common TEAEs were diarrhea (86.7%), increased alanine aminotransferase (55.0%), and increased aspartate aminotransferase (46.7%). No new safety signals emerged during the follow-up period. Bosutinib continues to demonstrate a favorable benefit/risk profile and is an important treatment option for Japanese patients with newly diagnosed CP-CML. Optimal management of TEAEs during initial treatment with bosutinib should be prioritized. Trial Registration: ClinicalTrials.gov ID: NCT03128411.

Combined Effects of 2-Methoxyestradiol (Hypoxia-Inducible Factor 1α Inhibitor) and Dasatinib (A Second-Generation Tyrosine Kinase Inhibitor) on Chronic Myelocytic Leukemia Cells. J Immunol Res 2022; 2022:6324326. [PMID: 35528614 PMCID: PMC9071866 DOI: 10.1155/2022/6324326] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 03/22/2022] [Accepted: 03/24/2022] [Indexed: 11/17/2022] Open
Abstract
Chronic myelocytic leukemia (CML) is a frequently encountered type of leukemia in China. Hypoxia-inducible factor 1 (HIF-1) serves as one of the most important factors of oxygen balance transcription. The activation of this gene mostly marks a poor outlook for cancer patients. To clarify the therapeutic effect of inhibiting this gene on CML, the present study is aimed at exploring the treatment effects of 2-methoxyestradiol (2-ME2), dasatinib alone, and combined both on K-562 cells and the possible mechanism of 2-ME2 in treating the disorder. The levels of HIF-1α, vascular endothelial growth factor (VEGF), and glutamate synthase 1 (GLU1) genes in K-562 cells were affected dose-dependently after 2-ME2 administration. 2-ME2 induced cell apoptosis by downregulating antiapoptotic protein expressions of Bcl-xl and Bcl-2. The therapeutic effect of single 2-ME2 was superior to single dasatinib, and the effect of combined therapy of both drugs produced better effectiveness than either of the single drug. Once the concentration of 2-ME2 exceeded 0.5 μM, downregulated C-myc gene expression could exert roles in anti-CML cell proliferation and inducing apoptosis. Dasatinib might participate in the inhibition of the C-myc pathway during this process whereas its effect remained not clear. Taken together, abnormal high expression of HIF-1α exerted an essential role in CML occurrence and development. Inhibition of this gene could markedly increase cell apoptosis in a dose-dependent fashion. Moreover, 2-ME2 could induce cell apoptosis by downregulating the C-myc gene and exert an apoptotic effect by downregulating Bcl-xl and Bcl-2 which act as antiapoptotic proteins.

Abstract
Bosutinib has been investigated in multiple clinical trials globally, including Japan, for treatment of chronic myeloid leukemia (CML). A pooled analysis of seven Pfizer-sponsored clinical trials evaluated the safety of bosutinib in Japanese (n = 138) vs non-Japanese (n = 1210) patients with CML. First-line bosutinib was administered in 54.3% vs 41.4% of patients, and second-line or later bosutinib in the remainder. Median treatment duration was 1.4 vs 2.3 years, and median relative dose intensity 78.1% vs 90.0%. Any-grade treatment-emergent adverse events (TEAEs) occurred in 100.0% vs 98.9% (grade ≥ 3: 81.9% vs 75.2%). In both groups, the most common TEAEs relevant to bosutinib were gastrointestinal (92.8% vs 84.7%), liver function (72.5% vs 34.8%), rash (63.8% vs 37.4%), and myelosuppression (55.1% vs 50.7%). TEAEs led to dose reduction in 65.2% vs 50.6%, dose interruption in 78.3% vs 68.8%, and permanent treatment discontinuation in 30.4% vs 25.4% of patients. The safety profile of bosutinib in Japanese patients was generally consistent with that in non-Japanese patients, despite a higher incidence of gastrointestinal, liver function, and rash events. TEAEs were largely manageable with dose modifications and supportive care in both groups. These data may help optimize TEAE management and outcomes in Japanese patients receiving bosutinib for CML. Trial registration ClinicalTrials.gov: NCT02130557, NCT03128411, NCT00574873, NCT00261846, NCT01903733, NCT00811070, NCT02228382.

Abstract
Background:
Despite the beneficial effects of
BCR-ABL1
tyrosine kinase inhibitors (TKIs) in the treatment of chronic myeloid leukemia (CML), they may also cause adverse events (AEs), especially cardiovascular toxicity. The incidence of TKI-induced AEs may vary among ethnic groups, and there is little specific information for Japanese patients. Methods and Results:
Sixty-nine consecutive patients who were started on treatment with dasatinib (n=25) or imatinib (n=44) for CML or gastrointestinal stromal tumor (GIST) between December 2008 and December 2019 were retrospectively recruited to the study. We determined the prevalence of AEs through October 2020 and compared the incidence of AEs between the 2 drugs. Baseline characteristics were comparable between the 2 groups. However, compared with the imatinib-treated group, the dasatinib-treated group had a higher incidence of congestive heart failure (CHF; 20.0% vs. 2.3%; P=0.04), pleural effusion (48% vs. 20.5%; P=0.03), pericardial effusion (24% vs. 4.6%; P=0.02), QT prolongation (4 vs. 0 patients; P=0.02), and pulmonary hypertension (3 vs. 0 patients; P=0.04). In the dasatinib-treated group, CHF tended to be associated with tricuspid valve regurgitation pressure gradient, and pleural effusion was observed in all patients. All-cause mortality and other cardiovascular events did not differ significantly between the 2 groups. Conclusions:
Cardiotoxic AEs occurred more frequently in Japanese patients with CML and GIST treated with dasatinib than imatinib.

Which Tyrosine Kinase Inhibitors Should Be Selected as the First-Line Treatment for Chronic Myelogenous Leukemia in Chronic Phase? Cancers (Basel) 2021; 13:cancers13205116. [PMID: 34680265 PMCID: PMC8534191 DOI: 10.3390/cancers13205116] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2021] [Revised: 10/09/2021] [Accepted: 10/09/2021] [Indexed: 01/06/2023] Open
Abstract
Simple Summary This review discusses the optimal selection of BCR-ABL1 tyrosine kinase inhibitors (TKIs) as the first-line treatment for newly diagnosed chronic myelogenous leukemia in chronic phase (CML-CP). With the advent of TKIs, the treatment goals for CML-CP patients have changed from “simply survival” to “survival with adequate quality of life”, hence the number of CML-CP patients aiming to achieve treatment-free remission has increased, irrespective of age or comorbidities. Therefore, optimal selection of TKIs for maximizing the number of patients to achieve treatment-free remission is an important factor for consideration in future studies. To this end, we must understand the advantages and disadvantages of each TKI in terms of treatment response, disease risk at diagnosis, comorbidities, and medical expenses, and use of effective 2GTKIs based on patient background. This review provides insights into “shared decision-making” in individual cases, including the elderly population. Abstract With the use of tyrosine kinase inhibitors (TKIs), chronic myelogenous leukemia in chronic phase (CML-CP) has been transformed into a non-fatal chronic disease. Hence, “treatment-free remission (TFR)” has become a possible treatment goal of patients with CML-CP. Currently, four types of TKIs (imatinib, nilotinib, dasatinib, and bosutinib) are used as the first-line treatment for newly diagnosed CML-CP. However, the second-generation TKI (2GTKI), the treatment response of which is faster and deeper than that of imatinib, is not always recommended as the first-line treatment for CML-CP. Factors involved in TKI selection in the first-line treatment of CML-CP include not only patients’ medical background, but also patients’ choice regarding the desired treatment goal (survival or TFR?). Therefore, it is important that clinicians select an appropriate TKI to successfully achieve the desired treatment goal for each patient, while minimizing the development of adverse events. This review compares the pros and cons of using imatinib and 2GTKI for TKI selection as the first-line treatment for CML-CP, mainly considering treatment outcomes, medical history (i.e., desire for pregnancy, aging factor, and comorbidity), and cost. The optimal use of 2GTKIs is also discussed.

Nilotinib vs. imatinib in Japanese patients with newly diagnosed chronic myeloid leukemia in chronic phase: 10-year follow‑up of the Japanese subgroup of the randomized ENESTnd trial. Int J Hematol 2021; 115:33-42. [PMID: 34508295 DOI: 10.1007/s12185-021-03216-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Revised: 09/01/2021] [Accepted: 09/01/2021] [Indexed: 12/12/2022]
Abstract
In the 10-year analysis of Japanese patients with newly diagnosed CML-CP in the ENESTnd trial, nilotinib yielded higher cumulative response rates. There were no new occurrences of disease progression or deaths since the 5-year analysis. Cumulative 10-year rates of MMR and MR4.5 were higher in the nilotinib arms [300 mg twice daily (BID), 86.2% and 69.0%, respectively; 400 mg BID, 78.3% and 69.6%, respectively] than the imatinib arm (400 mg once daily, 60.0% and 48.0%, respectively). Nasopharyngitis (85.7%, 77.3%, 79.2%), rash (50.0%, 68.2%, 37.5%), headache (39.3%, 45.5%, 25.0%), and back pain (39.3%, 50.0%, 29.2%) were the most frequently reported all-grade adverse events (AEs) for nilotinib 300 and 400 mg BID and imatinib, respectively. Cardiovascular AEs were more common with nilotinib than with imatinib. More patients on nilotinib had pre-diabetic and diabetic levels of HbA1c (300 mg BID, 17.9% and 10.7%, respectively; 400 mg BID, 22.7% and 18.2%, respectively) compared with imatinib (4.2% each). Overall, 10-year results from the Japanese cohort are consistent with prior results from the full ENESTnd cohort and the Japanese subgroup, and continue to support the long-term use of nilotinib in Japanese patients with newly diagnosed CML-CP, but with proper monitoring and management of comorbidities.

[PMID: 32279228 DOI: 10.1007/s12185-020-02878-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Revised: 04/03/2020] [Accepted: 04/03/2020] [Indexed: 12/11/2022]
Abstract
This open-label, single-arm, phase 2 study (ClinicalTrials.gov, NCT03128411) evaluated the efficacy, safety, and pharmacokinetics of bosutinib at a starting dose of 400 mg once daily (QD) in Japanese patients with newly diagnosed chronic phase chronic myeloid leukemia (CP CML). The primary endpoint was major molecular response (MMR) at Month 12 in the modified as-treated population (Philadelphia chromosome-positive [Ph+] patients with e13a2/e14a2 transcripts). Sixty Japanese patients with CP CML were treated with bosutinib; median age was 55 years (range 20-83), 60.0% were males, and all were Ph+ and had e13a2/e14a2 transcripts. After median follow-up of 16.6 months (range 11.1-21.9), 41 (68.3%) patients remained on bosutinib. The MMR rate at Month 12 was 55.0% (2-sided 90% confidence interval: 44.4-65.6). There were no on-treatment transformations to accelerated/blast phase, and no patient died on treatment or within 28 days of the last bosutinib dose. The most common treatment-emergent adverse events were diarrhea (86.7%), increased alanine aminotransferase (55.0%), and increased aspartate aminotransferase (46.7%). The primary objective of this phase 2 study was met, and there were no new safety signals for bosutinib. These data suggest bosutinib is an effective first-line treatment option for Japanese patients with newly diagnosed CP CML.

Influence of proton pump inhibitors and H2-receptor antagonists on the efficacy and safety of dasatinib in chronic myeloid leukemia patients. Int J Hematol 2020; 111:826-832. [PMID: 32152877 DOI: 10.1007/s12185-020-02845-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2019] [Revised: 02/27/2020] [Accepted: 02/28/2020] [Indexed: 10/24/2022]
Abstract
We evaluated the effect of proton pump inhibitors (PPIs) and H2-receptor antagonists (H2RAs) on the efficacy and safety of dasatinib for chronic-phase chronic myeloid leukemia (CP-CML). Retrospective analyses were performed for patients with CP-CML who received dasatinib at seven hospitals between April 2009 and December 2016. Seventy-three patients were identified, 16 of whom received PPIs or H2RAs concurrently with dasatinib. Major molecular response at 12 months was observed in 13 of 13 patients (100%) with concurrent PPIs or H2RAs (combination group), and in 23 of 51 patients (45.1%) who received only dasatinib (dasatinib-alone group; P < 0.001). Deep molecular response at 12 months was observed in four of six patients (66.7%) in the combination group, and seven of 38 patients (18.4%) in the dasatinib-alone group (P = 0.027). Dasatinib chemotherapy was stopped after 18 months for 25 patients (43.9%) from the dasatinib-alone group, but for none from the combination group. Combination treatment with PPIs or H2RAs did not reduce the efficacy of dasatinib. PPIs and H2RAs reduce the incidence of dasatinib discontinuation due to adverse events and increase the efficacy of dasatinib chemotherapy for patients.

Abstract
PURPOSE Inspired by the American Society of Clinical Oncology's recommendations to strengthen the evidence base for older adults with cancer, the purpose of this systematic review is to identify the reporting of treatment efficacy and adverse events specific to older adults with cancer in Phase III chemo-therapeutic clinical trials. This review also investigates the frequency with which these data points were reported in the literature to identify gaps in reporting and opportunities to expand the knowledge base on clinical outcomes for older adults with cancer. METHODS Chemo-therapeutic clinical trial data published from July 1, 2016 to June 30, 2017 was reviewed. Manuscripts (n = 929) were identified based on keyword searches of EMBASE and PubMed. After removal of duplicates (n = 116) and articles that did not meet this study's inclusion criteria (n = 654), 159 articles were identified for review. RESULTS Reviewed papers were published in 36 different scientific journals and included twenty-five different cancer types. Of the 159 articles, 117 (73.6%) reported age-specific medians and 75 (47.2%) included stratifications of data by age. Treatment efficacy was reported in 96.2% of the articles with 39.9% reporting effectiveness of treatment by age. Reporting of adverse events was included in 84.9% of the articles with only 8.9% reporting these events stratified by age. CONCLUSION Results suggest inadequate reporting of treatment efficacy and adverse events as well as basic descriptive statistics about the age distribution of study subjects. Conscious efforts are needed to address these deficiencies at every level of planning and conducting clinical trials as wells as reporting outcomes stratified by age. Ultimately, standardized reporting could lead to improved treatment decisions and outcomes for older adults with cancer.

Abstract
Treatment outcomes for chronic myeloid leukemia (CML) have dramatically improved with the development of tyrosine kinase inhibitors (TKI). However, due to the improved prognosis for CML, problems have arisen from long-term administration of TKI. The present study sought to verify whether more patients could achieve treatment-free remission (TFR) after stopping the administration of dasatinib using dasatinib as frontline treatment. Treatment-naïve chronic phase CML cases were treated with dasatinib as frontline treatment. Dasatinib treatment was stopped for 26 patients who achieved deep molecular response (DMR) within 24 months and were able to maintain DMR for an additional 2 years. Ten patients (38.5%) achieved DMR maintenance after 12 months. Recurrence was confirmed in 16 patients, and the median recurrence-free survival time was 5.1 months. The cumulative DMR rates at six and 12 months after restarting treatment were 84.6% and 100%, respectively. The results of this study demonstrated that the DMR maintenance rate after 12 months was 38.5%, which was not significantly different from previous TKI stop trials. The 2-year dasatinib administration period after reaching DMR did not contribute to improve TFR rates. These results suggest that the type of TKI is not associated with better TFR rates.

Abstract
OBJECTIVE Chronic myeloid leukemia (CML) is a rare malignancy in kidney transplant (KT) recipients. Although dasatinib is the first-line treatment for CML, it has inhibitory activity against CYP3A4; this might increase the blood concentration of tacrolimus (administered to KT patients for immune suppression). Furthermore, tacrolimus can also increase blood concentrations of dasatinib through P-glycoprotein inhibition. METHODS Here, we report a case of sustained molecular remission of CML with prolonged first-line dasatinib therapy in a KT recipient being treated with tacrolimus. A 61-year-old woman developed CML-chronic phase (CML-CP) 38 months post KT. Her maintenance immunosuppressive therapy consisted of tacrolimus, mycophenolate mofetil, and methylprednisolone. Considering the potential drug interaction with tacrolimus, dasatinib was administered at a low dose of 50 mg/day. Her immune status was evaluated regularly by assessing the mixed lymphocyte reaction (MLR) using an intracellular carboxyfluorescein diacetate succinimidyl ester (CFSE)-labeling technique; immunosuppressive therapy was adjusted accordingly. RESULTS The patient achieved complete hematologic remission (CHR) after 1 month of dasatinib treatment. Six months after dasatinib treatment, she achieved a major molecular response. During the observation period, neither antibody-mediated nor acute cellular rejection were encountered in the patient. She remained in CHR with a major molecular response 12 months after the diagnosis of CML-CP. CONCLUSION Data obtained from immune monitoring assays using CFSE-MLR helped us to successfully manage a KT recipient with CML-CP being treated with dasatinib. Drug-drug interactions are a key consideration while designing treatment regimens; such strategies would ensure that drug-drug interactions do not negatively affect the treatment outcomes.

Comparative efficacy and tolerability of front-line treatments for newly diagnosed chronic-phase chronic myeloid leukemia: an update network meta-analysis. BMC Cancer 2019; 19:849. [PMID: 31462241 PMCID: PMC6714291 DOI: 10.1186/s12885-019-6039-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2019] [Accepted: 08/14/2019] [Indexed: 01/05/2023] Open
Abstract
Background Recent years have witnessed the rapid evolution of therapies in chronic-phase chronic myeloid leukemia (CP-CML). To assess the efficacy and tolerability of all reported front-line treatments for patients with newly diagnosed CML, a multiple-treatments meta-analysis was performed, which accounted for both direct and indirect comparisons among those treatments. Methods Primary outcomes were the percentage of patients achieving major molecular response (MMR) and complete cytogenetic response (CCyR) within 12 months. Secondary outcomes included the percentage of progression to accelerated phase (AP), serious adverse effects (AEs), overall discontinuation and discontinuation for drug-related AEs. Direct pairwise meta-analysis and indirect multi-comparison meta-analysis among those treatments in each outcome were both conducted. The surface under the cumulative ranking curve (SUCRA) was calculated for all treatments in each outcome. Cluster analysis demonstrated the division of treatments into distinct groupings according to efficacy and tolerability profiles. Results A total of 21 randomized controlled trials (RCTs, including 10,187 patients) comparing 15 different interventions for CP-CML patients were included in this study. SUCRA analysis suggested that all tyrosine kinase inhibitors (TKIs) are highly effective in newly diagnosed CP-CML when compared to traditional drugs. Newer TKIs and higher-dose imatinib generally resulted in faster cytogenetic and molecular responses when compared with standard-dose imatinib and traditional drugs. Furthermore, traditional drugs, higher-dose imatinib and newer TKIs demonstrated lower acceptability than standard-dose imatinib. One cluster of interventions, which included nilotinib (300/400 mg BID), dasatinib (100 mg QD) and radotinib (300 mg BID), demonstrated higher efficacy and tolerability than other treatments. Conclusions Nilotinib (300/400 mg BID), dasatinib (100 mg QD) and radotinib (300 mg BID) prove to be the most recommended front-line treatments of the greatest efficacy and tolerability for CP-CML patients. High-dose therapies are recommended only for patients in accelerated phase/blast phase or with suboptimal CML-CP response, and management of adverse events should be carried out to avoid compromising the clinical efficacy.

Abstract
Dasatinib induces lymphocytosis of large granular lymphocytes (LGLs) in a proportion of patients with chronic myelogenous leukemia (CML), and is associated with better clinical outcomes. LGLs consist of cytotoxic T lymphocytes and natural killer cells; however, the context and phenotypic/functional features of each type of LGL are unknown. To better define features of these LGLs, we investigated lymphocytosis in CML patients treated with dasatinib. D57-positive and CD4-positive type I T-helper (Th) cells (CD57+ Th cells) rarely occur in CML patients without lymphocytosis and in healthy individuals; however, a substantial increase in the proportion of CD57+ Th cells was observed in CML patients treated with dasatinib. In addition, these cells showed appreciable levels of cytocidal activity via cytotoxic degranulation. Analysis of T-cell receptor α and β sequences showed a skewed T-cell repertoire in the CD57+ Th cells. Furthermore, patients with LGLs and CD57+ Th lymphocytosis achieved stronger molecular responses than did those without lymphocytosis. While further studies are warranted, our observations suggest that dasatinib induces the expansion of CD57+ Th-LGLs, which may play a crucial role in the dasatinib-induced response against Philadelphia chromosome-positive leukemia.

Abstract
This study investigated the incidence rate and features of vascular adverse events (VAEs) in Japanese patients with chronic myeloid leukemia (CML) who were treated with tyrosine kinase inhibitors (TKIs). The analysis included 369 CML patients in the chronic or accelerated phases, selected from the CML Cooperative Study Group database; 25 events in 23 (6.2%) of these patients were VAEs. At the time of VAE incidence, nine patients were on treatment with imatinib, 12 with nilotinib, three with dasatinib, and one with bosutinib. VAE incidence comprised 13 cases of ischemic heart disease (IHD), eight of cerebral infarction (CI), and four of peripheral arterial occlusive disease (PAOD). IHD incidence rate in the study population was higher than that in the age-matched general population, particularly in nilotinib-treated patients, while CI incidence rate was almost equivalent. Compared with the Suita score, the SCORE chart and the Framingham score risk assessment tools detected more patients with high or very high risk of VAEs. In conclusion, incidence of IHD requires closer monitoring in nilotinib-treated patients. More detailed investigations for determining the most useful tool to predict VAE incidence and long-term analysis of therapy-related VAE cases are needed for improving safety during TKI therapy.

Abstract
OBJECTIVE This multicenter cooperative study aimed to analyze the adverse events (AEs) associated with tyrosine kinase inhibitors (TKIs) used as initial treatment for chronic-phase chronic myeloid leukemia (CML-CP) and their impact on outcome. METHODS We retrospectively evaluated 450 patients with CML-CP who received TKIs between 2004 and 2014. RESULTS The 5-year overall survival (OS) and event-free survival (EFS) rates were 95.1% and 89.0%, respectively. Patients with comorbidities (46.4%) and aged ≥60 years (50.4%) at diagnosis had significantly inferior OS to those without comorbidities and aged <60. Patients achieved higher rates of major molecular response (MMR) at 6 and 12 months after initial treatment with dasatinib or nilotinib compared to imatinib, but final MMR rates were almost the same. Sixty-six percent of patients required treatment modifications from first-line TKI therapy; the main reasons were AEs (48.4%) and failure (18%). Grade III-IV AEs in first-line TKI therapy were significantly correlated to inferior OS/EFS compared to grade 0-II AEs. CONCLUSION Although long-term outcomes were similar in CML-CP patients treated with each TKI regardless of first-line TKI selection, severe AEs in first-line TKI therapy decreased their survival rates. Early change in TKIs is recommended, when faced with severe AEs of specific TKIs.

Therapeutic effects of tyrosine kinase inhibitors and subtypes of BCR-ABL1 transcripts in Japanese chronic myeloid leukemia patients with three-way chromosomal translocations. Leuk Res 2018; 65:74-79. [PMID: 29310021 DOI: 10.1016/j.leukres.2018.01.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2017] [Revised: 12/30/2017] [Accepted: 01/02/2018] [Indexed: 10/18/2022]
Abstract
We analyzed the clinical responses to thyrosine kinase inhibitors (TKIs) and the molecular and cytogenetic characteristics of 18 chronic myeloid leukemia (CML) patients with 3-way chromosomal translocations. The patients were 14 men and 4 women, aged 23-75 years (median 57 years). The Sokal risk was low in 12 patients, intermediate in 4 patients, and high in 2 patients. Newly identified translocation breakpoints were seen in 7 of the 18 patients. Three patients had the same breakpoints of t(9;22;11)(q34;q11.2;q23). The best responses to TKIs were partial cytogenic response (PCyR) in 2 patients, complete cytogenic response (CCyR) in 3 patients, molecular response (MR) 3.0 in 7 patients, MR 4.0 in 3 patients, and MR 4.5 or higher in 3 patients. A total of 66.7% of patients did not achieve MR 4.0 or higher. In 3 patients in whom TKIs resulted in MR 4.5 or higher for more than 2 years, TKI treatment was discontinued. However, all of them exhibited a loss of MR3.0, at 2, 6, and 20 months after the discontinuation of treatment, respectively, and TKI treatment needed to be restarted. According to Kaplan-Meier survival curve analysis, the overall survival (OS) was 100 months in 56% of the patients. The 60-months cumulative incidences of CCyR, MR3.0, MR4.0 and MR4.5 were 88.9%, 72.2%, 33.3%, and 16.7%, respectively. In the 11 analyzable patients, the BCR-ABL1 mRNA subtype was e14a2 type in 4 patients and e13a2 type in 7 patients.

Abstract
Wilms' tumor 1 (WT1) is overexpressed in various hematopoietic tumors and widely used as a marker of minimal residual disease. WT1 mRNA has been analyzed using quantitative real-time polymerase chain reaction (real-time PCR). In the present study, we analyzed 40 peripheral blood and bone marrow samples obtained from cases of acute myeloid leukemia, acute lymphoblastic leukemia, and myelodysplastic syndrome at Sapporo Medical University Hospital from April 2012 to January 2015. We performed quantification of WT1 was performed using QuantStudio 3D Digital PCR System (Thermo Fisher Scientific) and compared the results between digital PCR and real-time PCR technology. The correlation between digital PCR and real-time PCR was very strong (R = 0.99), and the detection limits of the two methods were equivalent. Digital PCR was able to accurately detect lower WT levels compared with real-time PCR. Digital PCR technology can thus be utilized to predict WT1/ABL1 expression level accurately and should thus be useful for diagnosis or the evaluation of drug efficiency in patients with leukemia.
