Gastrointestinal Adverse Events

Tyrosine kinase inhibitors (TKIs) are the frontline therapy for BCR-ABL (Ph+) chronic myeloid leukemia (CML). A systematic meta-analysis of 43 peer-reviewed studies with 10,769 CML patients compared the incidence of gastrointestinal adverse events (GI AEs) in a large heterogeneous CML population as a function of TKI type. Incidence and severity of nausea, vomiting, and diarrhea were assessed for imatinib, dasatinib, bosutinib, and nilotinib. Examination of combined TKI average GI AE incidence found diarrhea most prevalent (22.5%), followed by nausea (20.6%), and vomiting (12.9%). Other TKI GI AEs included constipation (9.2%), abdominal pain (7.6%), gastrointestinal hemorrhage (3.5%), and pancreatitis (2.2%). Mean GI AE incidence was significantly different between TKIs (p < 0.001): bosutinib (52.9%), imatinib (24.2%), dasatinib (20.4%), and nilotinib (9.1%). Diarrhea was the most prevalent GI AE with bosutinib (79.2%) and dasatinib (28.1%), whereas nausea was most prevalent with imatinib (33.0%) and nilotinib (13.2%). Incidence of grade 3 or 4 severe GI AEs was ≤3% except severe diarrhea with bosutinib (9.5%). Unsupervised clustering revealed treatment efficacy measured by the complete cytogenetic response, major molecular response, and overall survival is driven most by disease severity, not TKI type. For patients with chronic phase CML without resistance, optimal TKI selection should consider TKI AE profile, comorbidities, and lifestyle.

AbstractMutations in the Bcr-Abl kinase domain may cause, or contribute to, resistance to tyrosine kinase inhibitors (TKIs) in chronic myeloid leukemia patients. Recommendations aimed to rationalize the use of BCR-ABL mutation testing in chronic myeloid leukemia have been compiled by a panel of experts appointed by the European LeukemiaNet (ELN) and European Treatment and Outcome Study and are here reported. Based on a critical review of the literature and, whenever necessary, on panelists' experience, key issues were identified and discussed concerning: (1) when to perform mutation analysis, (2) how to perform it, and (3) how to translate results into clinical practice. In chronic phase patients receiving imatinib first-line, mutation analysis is recommended only in case of failure or suboptimal response according to the ELN criteria. In imatinib-resistant patients receiving an alternative TKI, mutation analysis is recommended in case of hematologic or cytogenetic failure as provisionally defined by the ELN. The recommended methodology is direct sequencing, although it may be preceded by screening with other techniques, such as denaturing-high performance liquid chromatography. In all the cases outlined within this abstract, a positive result is an indication for therapeutic change. Some specific mutations weigh on TKI selection.

Metabolomic Analysis

Background: Cardiovascular adverse events (CV-AEs) are considered critical complications in chronic myeloid leukemia (CML) patients treated with second- and third-generation tyrosine kinase inhibitors (TKIs). The aim of our study was to assess the correlation between metabolic profiles and CV-AEs in CML patients treated with TKIs. Methods: We investigated 39 adult CML patients in chronic-phase (mean age 49 years, range 24–70 years), with no comorbidities evidenced at baseline, who were consecutively identified with CML and treated with imatinib, nilotinib, dasatinib, and ponatinib. All patients performed Gas-Chromatography-Mass-Spectrometry-based metabolomic analysis and were divided into two groups (with and without CV-AEs). Results: Ten CV-AEs were documented. Seven CV-AEs were rated as 3 according to the Common Toxicity Criteria, and one patient died of a dissecting aneurysm of the aorta. The patients’ samples were clearly separated into two groups after analysis and the main discriminant metabolites were tyrosine, lysine, glutamic acid, ornithine, 2-piperdinecarboxylic acid, citric acid, proline, phenylalanine, threonine, mannitol, leucine, serine, creatine, alanine, and 4-hydroxyproline, which were more abundant in the CV-AE group. Conversely, myristic acid, oxalic acid, arabitol, 4-deoxy rithronic acid, ribose, and elaidic acid were less represented in the CV-AE group. Conclusions: CML patients with CV-AEs show a different metabolic profile, suggesting probable mechanisms of endothelial damage.

Abstract Abstract 4458 Chronic Myeloid Leukemia (CML) is a clonal myeloproliferative disorder characterized by the presence of a balanced reciprocal translocation involving the long arms of chromosomes 9 and 22. The fusion gene that is created by this translocation (BCR-ABL1) encodes for a constitutively active protein tyrosine kinase that is primarily responsible for the leukemic phenotype. Targeted therapy with Tyrosine Kinase Inhibitors (TKIs) has become the recommended first-line treatment for patients with CML. Monitoring of the CML is done with quantification of the BCR-ABL transcripts by RQ-PCR–based molecular technique. Twenty nine patients were diagnosed with CML in chronic phase between January 2009 till June 2012. The median age was 32 years (range 22–68 years). Male to female ratio was4.14:1. Three patients were lost from follow up after diagnosis and are excluded. Molecular response is available for 16 patients. Nine patients were treated with Imatinib 400 mg daily, four with Dasatinib 100 mg daily and three with Nilotinib 400 mg BID daily as upfront therapy. Twelve patients have achieved MMR/CMR (75 %) within 18months of starting therapy. Four patients have failed to achieve MMR by 24 months. All non responders were on Imatinib. Interestingly six (37.5%) patients achieved MMR/CMR within 9 months of starting TKIs. Of these only 1 was on Imatinib while the rest were on 2nd generation TKIs (Nilotinib 3 and Dasatinib 2). MMR report from Enestnd trial is 67–71% in favor of Nilotinib as compared to Imatinib 44%, while the Dasision trial reported a MMR of 44 % in favor of Dasatinib with faster rate to response. Our results mirror the results of these phase 3 randomized trial with MMR/CMR of 75 %. Until today there has been no case of progressive disease. Our data is limited but shows that the median age is much lower compared to Western countries, just reflecting differences in the age distribution of the population in the UAE with 80% being below the age of 65 years. Expatriates accounts for approximately 80% of the population in the UAE and many are temporary employed, having limited health care coverage, limited financial means as well as limited possibilities to attend regular follow-ups. This leads to compliance problems, loss from follow-up and suboptimal management and monitoring of their disease. Disclosures: Alam: BMS/Novartis: Consultancy, Honoraria.

Abstract Background and Objectives: In clinical, conventional Tyrosine Kinase Inhibitors (TKIs) including imatinib, dasatinib, and nilotinib are remarkably effective forms of therapy for certain types of solid cancers as well as Ph+ leukemias. In addition to the BCR-ABL target oncoprotein, they also inhibit certain off-target kinases (Eph, c-KIT, TEC, SRC). Some TKIs affect immune reconstitution as well as the proliferation, function, and activation of T cells. Certain TKIs have been known to have an especially strong effect on CD4+CD25+ T cells, also known as regulatory T Cells (Tregs). There is currently a gap in the clinical data available about on this area of study. Patients and methods: In this study, we collected 108 Peripheral Blood (PB) samples from patients in the Chronic Phase (CP) of Chronic Myeloid Leukemia (CML) at the time of diagnosis (n=31) and also the TKIs treatment. Groups consisted of individuals treated with TKIs like imatinib (n=12), dasatinib (n=11) and nilotinib (n=8), as well as healthy controls (n=15). We evaluated the quantity and function of Tregs from patients in the CML-CP at the time of diagnosis and during treatment with TKIs. Results: It was found that at diagnosis, patients with CML had a similar proportion and absolute number of lymphocytes compared to healthy donors. After TKIs treatment, proportions and absolute numbers of total T cellsACD4+ T cells and Tregs decreased at different degree. Moreover, thedecrease would be more and more significant as time goes on.Our results indicated that although these three TKIs show similar inhibitory effects in the proportion and number of Tregs in vivo, they have differential effects on the functions of Tregs in vitro. The proliferation, suppression, and expression of suppressive cytokines (IL-4,IL-10 and TGF-β) as well as suppression-associated molecules (FoxP3, GITR, and CTLA-4) of Tregs decreased in groups treated with imatinib and dasatinib. The decrease was not significant in the nilotinib-treated group. Conclusions: The results showed that imatinib and dasatinib have stronger inhibitory roles than nilotinib when it comes to regulating the number and functions of Tregs. These findings can be used to argue in favor of calls for personalized treatment and follow-up of CML patients during TKIs treatment, particularly for those patients who received combination therapy with allo-transplantation and post-transplant TKIs.
