Impact of the treatment of chronic myeloid leukaemia by tyrosine-kinase inhibitors on sick leaves refund: a nationwide cohort study. Support Care Cancer 2022; 30:5431-5440. [PMID: 35304631 DOI: 10.1007/s00520-022-06968-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2021] [Accepted: 03/10/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND The advent of chronic myeloid leukaemia (CML) tyrosine-kinase inhibitors (TKI) has led to new paradigms including occupational rehabilitation. OBJECTIVES This study aimed to characterize the impact of CML treatment on sick leaves within the 2 years following diagnosis in working-age patients. METHODS A cohort of all 18-60-year-old newly diagnosed CML patients initiating a TKI between January 1st 2011 and December 31st 2014 in France was identified in the French National Healthcare database (Système National des Données de Santé [SNDS]). Patients with a sick leave identified in the 24 months after TKI initiation were compared with sex and initiation date matched controls in a nested case-control design. Factors associated with sick leaves were identified through a conditional logistic regression model, providing adjusted odds-ratio (OR) with their 95% confidence interval (CI). RESULTS Among 646 18-60-year-old patients, 268 were prescribed at least one sick leave in the study period, with 176 (27.2%) having their first sick leave prescribed after TKI initiation. The median number of sick days over the 2-years period was 115 per patient (interquartile range 25.5-384.5). In the nested case-control study (176 cases and 176 matched controls), sick leaves were more likely observed with second generation TKI (OR 4.11 [1.80-9.38]), whereas they were less likely observed in case if social deprivation (OR 0.07 [0.02-0.28]. CONCLUSION More than 25% of working-age CML patients had at least one sick leave within 2 years of TKI initiation, with a higher impact of second generation TKI, and with a median duration of 115 days.

Efficacy and safety of anlotinib in patients with advanced malignancy: a single-center, single-arm, phase 2 trial. Int J Clin Oncol 2021; 26:1611-1618. [PMID: 34297245 DOI: 10.1007/s10147-021-01959-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2020] [Accepted: 05/28/2021] [Indexed: 12/23/2022]
Abstract
BACKGROUND For advanced tumors that lack specific oncogenic alteration and are resistant to chemotherapy, anti-angiogenesis therapy or immunotherapy or a combination of the two are the most important treatments. Anlotinib is a newly developed oral small molecule receptor tyrosine kinases inhibitor with the potency of inhibiting tumor angiogenesis. This was an open-label, single-arm, phase 2 study to validate the efficacy and safety of anlotinib in patients with various cancer types. METHODS Patients with advanced malignancy who have failed previous therapies or lack effective treatment choices received daily oral administration of 12 mg anlotinib on days 1-14 every 3 weeks until disease progression, intolerable toxicity or physician decision. The primary endpoint was objective response rate (ORR). RESULTS A total of 93 eligible patients with 26 different cancer types were enrolled. The overall ORR was 21.5%. The median PFS was 5.7 months and median OS was 12.0 months. The most common treatment-related AE of all grades and of grade 3 was both hypertriglyceridemia at an incidence of 40.9% and 5.4%, respectively. CONCLUSIONS Anlotinib exhibits objective efficacy and safety in advanced malignancy and might be a possible treatment option for many types of cancer patients who have failed prior treatment and with no optimal therapy regimen.

The multi-tyrosine kinase inhibitor ponatinib for chronic myeloid leukemia: Real-world data. Eur J Haematol 2020; 105:3-15. [PMID: 32145037 DOI: 10.1111/ejh.13408] [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: 11/12/2019] [Revised: 02/27/2020] [Accepted: 03/04/2020] [Indexed: 12/19/2022]
Abstract
Development of the highly selective targeted tyrosine kinase inhibitors (TKIs) has expanded the therapeutic options for chronic myeloid leukemia (CML). Patients undergoing TKI therapy should be closely monitored to ensure that the best therapeutic response and quality of life are achieved, and to control suboptimal responses and adverse events. Despite the high rate of response using current first-line TKIs, treatment failure may still occur, and resistance is considered a challenge in the treatment of patients with CML. The third-generation TKI, ponatinib, is a potent orally bioavailable pan BCR-ABL inhibitor that inhibits both wild-type and mutant BCR-ABL1 kinase, including the "gatekeeper" T315I mutation, which is resistant to all other currently available TKIs. This paper reviews the effectiveness, feasibility, and safety of ponatinib in the real-life clinical management of CML. Potential prognostic factors in identifying patients most likely to benefit from ponatinib treatment will be discussed, and case presentations illustrating situations encountered in real-life clinical practice are described. Ponatinib is effective in patients who have received prior TKIs in clinical studies as well as under real-life conditions. Nevertheless, the risk/benefit balance must be evaluated for each patient, particularly considering disease state, mutational status, treatment line, intolerance/resistance to prior TKIs, age, frailty, and specific comorbidities.

Pharmacology of tyrosine kinase inhibitors in chronic myeloid leukemia; a clinician's perspective. ACTA ACUST UNITED AC 2020; 28:371-385.

Abstract
OBJECTIVE In this review, we have summarized the pharmacokinetics, pharmacodynamics and adverse effects of imatinib, dasatinib, nilotinib, bosutinib, ponatinib and radotinib with focus on pharmacogenomic studies with clinical end points. We have discussed the key phase 3 trials of tyrosine kinase inhibitors (TKI) comparing with each other, treatment free remission (TFR) and selection of TKI. Upcoming concepts and related trials in the management of chronic myeloid leukemia (CML) along with future directions have been touched upon. EVIDENCE ACQUISITION PubMed, Embase, Google, Cochrane library and Medline were searched to identify relevant literature for the review. Clinicaltrial.gov was searched for upcoming data and trials. RESULTS There are lot of gap in pharmacokinetics and pharmacodynamics of TKI. Imatinib appears to be the safest TKI. Newer TKI's achieve better achievement of therapeutic milestones, deeper molecular response and less chances of progression of CML compared to imatinib. Newer TKI appears to be better choice for achieving TFR. When the objective is survival, imatinib is still the TKI of choice. Primary prophylaxis with antiplatelet drugs for TKI having cardiovascular and thromboembolic side effects should be considered. CONCLUSION Pharmacogenetic data of TKI is still immature to guide in therapeutic decision making in clinical practice. There is need for further research in pharmacology and pharmacogenomics of newer TKI's. Randomized controlled trials are required to decide the optimum TKI for TFR. Safe and effective TKI for targeting T315I mutation, CML accelerated phase and blast crisis are an active area of research.

Abstract
Treatment of chronic myeloid leukemia (CML) and Philadelphia chromosome-positive acute leukemia (Ph+ ALL) has been revolutionized with the advent of tyrosine kinase inhibitors (TKIs). Most patients with CML achieve long-term survival similar to individuals without CML due to treatment with TKIs not only in frontline but also in further lines of therapy. The third-generation TKI ponatinib has demonstrated efficacy in patients with refractory CML and Ph+ ALL. Ponatinib is currently the most potent TKI in this setting demonstrating activity against T315I mutant clones. However, ponatinib's safety data revealed a dose-dependent, increased risk of serious cardiovascular (CV) events. Guidance is needed to evaluate the benefit-risk profile of TKIs, such as ponatinib, and safety measures to prevent treatment-associated CV events. An expert panel of German hematologists and cardiologists summarize current evidence regarding ponatinib's efficacy and CV safety profile. We propose CV management strategies for patients who are candidates for ponatinib.

Abstract
OBJECTIVE To analyze the clinical features of chronic myeloid leukemia (CML) with T315 I mutation (CML-T315I) and compare the effectiveness of different treatments. METHODS We retrospectively analyzed the clinical data and outcomes of 19 patients with CML-T315I receiving different treatments. The T315 I mutations in these patients were detected by examination of BCR-ABL kinase domain (KD) mutation by RTQ-PCR and Sanger sequencing. The relapse following the treatments, defined as hematological, cytogenetic and molecular biological recurrences, were analyzed in these patients. RESULTS Of the 19 patients with CML-T315I, 14 (73.7%) were in CML-CP stage at the initial diagnosis, and 13 (81.2%) were high-risk patients based on the Sokal scores. All the 19 patients were treated with TKI after the initial diagnosis, and during the treatment, 15 (78.9%) patients were found to have additional chromosomal aberrations, and 10 (52.6%) had multiple mutations; 13 (68.4%) of the patients experienced disease progression (accelerated phase/blast crisis) before the detection of T315I mutation, with a median time of 40 months (5-120 months) from the initial diagnosis to the mutation detection. After detection of the mutation, 12 patients were treated with ponatinib and 7 were managed with the conventional chemotherapy regimen, and their overall survival rates at 3 years were 83.3% and 14.2%, respectively (P < 0.001). CONCLUSIONS CML patients resistant to TKI are more likely to have T315I mutations, whose detection rate is significantly higher in the progressive phase than in the chronic phase. These patients often have additional chromosomal aberrations and multiple gene mutations with poor prognoses and a high recurrence rate even after hematopoietic stem cell transplantation. Long-term maintenance therapy with ponatinib may improve the prognosis and prolong the survival time of the patients.

Abstract
There are five tyrosine kinase inhibitors (TKIs) that are currently approved (in the European Union and the United States) for the treatment of chronic myeloid leukaemia (CML) in the chronic phase (CP) and each of them has its own efficacy and toxicity profile. Oral ponatinib (Iclusig®) is a third-generation TKI structurally designed to inhibit native BCR-ABL1 tyrosine kinase and several BCR-ABL1 mutants, including T315I. Ponatinib is now approved for patients with CML who are resistant or intolerant to prior TKI therapy (European Union) or for whom no other TKI therapy is indicated (United States). Despite achieving results in heavily treated patients, which led to its approval, the drug may induce cardiovascular events, requiring a careful baseline assessment of predisposing risk factors and specific management during treatment. Pharmacokinetic analysis has indicated the possibility of reducing the starting dose of ponatinib to 15 mg/day and preliminary data showed advantages in terms of safety while maintained its efficacy. This review summarizes the results achieved and drug-related side effects reported in all clinical trials and real-life experiences, testing ponatinib in patients with CP-CML. In addition, we focus on the appropriate use of ponatinib in clinical practice suggesting some useful recommendations on the proper management of this drug.
