Epidemiologic Risk Factor

Once used only as third-line therapy in the management of chronic pain states, methadone is now being used as first- and second-line therapy. Most risks and the stigma associated with methadone use have been known for years. Only over the past decade or so have the unique pharmacokinetic-pharmacodynamic properties and methods for conversion from other opioids to methadone been established. Pertinent English-language literature was obtained from MEDLINE/PUBMED and EMBASE searches (1966-June 2009). This paper provides an overview of the cardiotoxicity of oral methadone, with an emphasis on its use as an analgesic. Cardiotoxicity during its use in the maintenance of opioid addiction has also been reviewed due to the wealth of epidemiologic, risk factor, and correlative analytic data contained therein. A series of recommendations are provided to improve the cardiac safety profile of oral methadone used for analgesia. In addition, there is a discussion of settings and patient types which may impact upon these recommendations.

Introduction. Nowadays urticaria is one of the most common diseases. According to the International Guidelines for the definition, classification, diagnosis and management of urticaria, 2nd-generation H1-antihistamines are recommended to be used as the first-line and second-line therapy. Omalizumab, a humanized monoclonal anti-IgE antibody, is assumed to be the third-line therapy in urticaria treatment. Summary. In this review we discuss the latest data on pathogenetic mechanisms of urticaria, focusing on the search of the new targets for the therapy. We represent the latest clinical trials of the new biological treatment for urticaria. Safety and efficiency of 4-folds higher therapeutical dose of the 2nd generation H1-antihistamines, and criteria for personalized selection of the antihistamines are discussed.

Abstract Abstract 3440 Nilotinib and dasatinib are second-generation tyrosine kinase inhibitors (TKI) used in patients with chronic myeloid leukemia (CML) resistant or intolerant to imatinib. There are no randomized clinical trials comparing these drugs in this context. The aim of this study was to compare, retrospectively, the hematological, cytogenetic and molecular response in patients submitted to these second-generation TKI at Hemorio, a public brazilian institution. A total of 114 patients were analyzed, 63 received nilotinib and 51 dasatinib as second-line therapy (55.3% and 44.7%, respectively). The following variables were equally distributed between these two groups (nilotinib vs. dasatinib, respectively): male sex (54% vs. 60.8%, p=0.46), median age at diagnosis (46 vs. 45 years, p=0.76), median time in months using imatinib before the switch (45.2 vs. 44.1, p=0.96), resistance to imatinib (98.4% vs. 98%, p=0.88), presence of the mutation T315I (3.2% vs. 3.9%, p=0.09), patients in chronic phase before the switch (85.7% vs. 86.3%, p=0.93). Use of another second generation TKI, as a third-line therapy, was necessary in 30 out of the 114 patients analyzed (26.1%) because of lack of response. This modification was slightly more frequent in the group initially submitted to nilotinib (31.7% vs. 19.6%, p=0.21). Patients who used a third-line therapy were excluded from response and survival analyzes. Response rates after the second-generation TKI were similar between these two groups (nilotinib vs. dasatinib): complete hematological response until three months (77.8% vs. 87.3%, p=0.24), complete cytogenetic response until six months (21.6% vs. 22.2%, p=0.95) and 12 months (32.4% vs. 33.3%, p=0.94) and major molecular response reached before 12 months (32.7% vs. 21.6%, p=0.25). Two-year overall survival (OS) and progression free-survival (PFS) were similar between these two groups (nilotinib vs. dasatinib, respectively): 92.2% vs. 87.8% (p=0.38) for OS and 87.8% vs. 83.7% (p=0.14) for PFS. Although not statistically significant, two-year OS was inferior in the group of patients who needed a third-line therapy (70.5% vs. 95.6%, p=0.70). Our results suggest that the response and survival rates are similar between nilotinib and dasatinib as second-line therapy for patients with imatinib resistant or intolerant CML. Also, they suggest an inferior prognosis for patients who need a third-line therapy. In this way, the choice between these two TKI for second-line therapy should be guided by the clinical characteristics and the mutation status of the patient.

430 Background: Third-line targeted therapy efficacy in metastatic renal cell carcinoma (mRCC) is not well characterized and many funding bodies do not provide reimbursement for it. Methods: The International mRCC Database Consortium (IMDC) consists of consecutive patient series from 25 cancer centers. It was queried for specific sequences of targeted therapy and third-line therapy. Kaplan Meier estimates were used for survival. Cox proportional hazards models were used to adjust hazard ratios for confounders. Patients that stopped second-line therapy were divided into two groups: those that went onto third-line therapy and those did not. Results: 4,050 patients were treated with first-line targeted therapy, of which 2,011 (49.6%) had second-line therapy and 879 (21.7%) had third-line targeted therapy. The most common third-line therapies were everolimus 25%, sorafenib 14%, sunitinib 13%, temsirolimus 11%, pazopanib 10%, and axitinib 6%. IMDC prognostic groups at third-line therapy initiation were 6% favorable risk, 67% intermediate risk, and 27% poor risk. Overall response rate for third-line therapy was 10.5% and 50.9% had stable disease in those patients that were evaluable. Median PFS was 5.1 months (95% CI, 4.5-5.7) and median OS from third-line therapy initiation was 12.0 months (95% CI, 10.7-12.9). Patients stopping second-line therapy that move on to third-line therapy vs. those that do not receive third line therapy have a median OS from stopping second-line therapy of 13.1 vs. 2.3 mons (p<0.0001). When adjusted for second-line IMDC prognostic criteria and KPS at second-line treatment cessation, patients who do receive third-line therapy have a HR of death of 0.41 (95% CI, 0.32-0.52; p<0.0001) compared to those that do not receive third-line therapy. This may be in part due to patient selection. To further limit bias, when excluding patients that live less than 3 months after second-line therapy cessation, the adjusted HR was similar. Conclusions: Third-line targeted therapy has demonstrated activity and is prevalent in use. Further studies are required to determine appropriate sequencing.

InterventionsTargeted therapies have been proven to provide clinical benefits to patients with metastatic non-small cell lung cancer (NSCLC). Gefitinib was initially approved and reimbursed as a third-line therapy for patients with advanced NSCLC by the Taiwan National Health Insurance (NHI) in 2004; subsequently it became a second-line therapy (in 2007) and further a first-line therapy (in 2011) for patients with epidermal growth factor receptor mutation-positive advanced NSCLC. Another targeted therapy, erlotinib, was initially approved as a third-line therapy in 2007, and it became a second-line therapy in 2008.ObjectivesThis study is aimed towards an exploration of the impacts of the Taiwan NHI reimbursement policies (removing reimbursement restrictions) related to accessibility of targeted therapies.SettingWe retrieved 2004–2013 claims data for all patients with lung cancer diagnoses from the NHI Research Database.Design and outcome measuresUsing an interrupted time series design and segmented regression, we estimated changes in the monthly prescribing rate by patient number and market shares by cost following each modification of the reimbursement policy for gefitinib and erlotinib for NSCLC treatment.ResultsTotally 92 220 patients with NSCLC were identified. The prescribing rate of the targeted therapies increased by 15.58%, decreased by 10.98% and increased by 6.31% following the introduction of gefitinib as a second-line treatment in 2007, erlotinib as a second-line treatment in 2008 and gefitinib as as first line treatment in 2011, respectively. The average time to prescription reduced by 65.84% and 41.59% following coverage of erlotinib by insurance and gefitinib/erlotinib as second-line treatments in 2007–2008 and following gefitinib as the first-line treatment in 2011.ConclusionsThe changes in reimbursement policies had a significant impact on the accessibility of targeted therapies for NSCLC treatment. Removing reimbursement restrictions can significantly increase the level and the speed of drug accessibility.

e18097 Background: Lung cancer is the most common cause of cancer-related death in men and women worldwide. 80% of the lung cancer patients are diagnosed with NSCLC. Patients have varying survival results from multiple lines of treatment. The objective of this study was to evaluate in a real world context, treatment patterns with survival, and the impact of adding a third line of chemotherapy to a stage III/IV NSCLC population. Methods: The Georgia Cancer Specialist database (2005-2011) was used. Patients with stage III or IV primary NSCLC and treated with chemotherapy were followed from initial NSCLC diagnosis until death, study end or lost to follow-up. Patients were stratified into lines and type of protocol for treatments. Kaplan-Meier curves were used to compare the overall survival results between lines of therapy. Results: A total of 291 patients with advanced NSCLC were identified and included in the primary analysis. Of these, 40 patients received third line therapy. The most commonly used treatment regimens in third line were Pemetrexed with 11 patients (3.8%), Docetaxel with 10 patients (3.4%), Gemcitabine with 4 patients (1.4%), Vinorelbine with 3 patients (1%) Cisplatin/Gemcitabine/Bevacizumab with 2 patients (0.7%). No single treatment regimen was predominantly used in third line. No association of survival gain was seen in patients who received third line therapy over those who received second line therapy (Log-Rank test P=0.4926) Conclusions: In a large EMR physician practice based database of advanced NSCLC patients, we failed to find a difference in the median overall survival of patients who received third line therapy compared to those who received second line therapy. Limitations include a small sample size and no standardized timing of diagnosis and treatment. The lack of a standard of care in third line therapy necessitates the need of further randomized controlled clinical studies to establish a benefit for a particular combination.

633 Background: Ras genes are markers of resistance to anti-EGFR therapies. Emerging evidences suggest that each mutation, independently from its predictive role of response/resistance to specific treatments, may be expression of different diseases with different biologic behaviours. We collected data of mCRC patients harbouring K-Ras codon 13 mutation to evaluate response to therapy, PFS and OS. Methods: We retrospectively collected data of advanced colorectal cancer patients harbouring K-Ras codon 13 mutation treated at our Institution between 2004 and 2014. Results: A total of n.33 K-Ras codon 13 mutated patients were analysed. N.24 patients (72,7%) had synchronous metastatic disease. None of the patients received anti-EGFR treatment, while n.25 patients received anti-VEGF agent bevacizumab in association to chemotherapy with fluoropirimidines plus oxaliplatin and/or irinotecan (n.21 as frontline therapy, n.4 in second line). ORR was 51,5% (17/33) on first-line therapy, 22,2% (6/27) on second-line therapy and 16,6% (2/12) on third-line therapy. Median PFS was 14,1 months after first-line therapy, 9,3 months after second-line therapy, 6,4 months after third-line therapy. Median OS was 35,5 months (events: 19/33). N.14 patients received metastases surgery with radical intent. OS in this population has not been reached yet at a median follow-up of 38 months, even though all patients had a relapse. OS among patients undergone to systemic only strategy was 31 months. Conclusions: At our knowledge, this is the first report suggesting a favourable prognosis for K-ras codon 13 mutated patients, with a median overall survival even superior to pan-RAS wild-type patients. Indeed, the high percentage of advanced patients at diagnosis (72.7%), the high responsiveness to chemotherapy even in third line, the high percentage of patients converted to surgery (42.4%) in an unselected population, together with the high risk or relapse after surgery, suggest K-ras codon 13 mutated disease is probably a biologically aggressive disease. Nevertheless our data prompt that these patients may benefit aggressive strategies of treatment and multidisciplinary evaluation.

Dasatinib Treatment

We retrospectively evaluated the efficacy and safety of dasatinib among 48 Chinese patients with chronic phase chronic myeloid leukaemia. The proportions of patients achieving the optimal molecular responses at 3, 6, and 12 months, a major molecular response (MMR) rate and a complete cytogenetic response (CCyR) rate were 87.0, 87.0, 72.2, 45.8, and 72.7% for patients with dasatinib as second-line therapy, and 34.8, 34.8, 33.3, 20.8, and 46.2% as third-line therapy, respectively. A BCR-ABL1 transcript level on the International Scale (BCR-ABL1IS) of ≤10% at the initiation of ­dasatinib treatment was found to be associated with a higher probability of achieving MMR. Among patients with a ­BCR-ABL1IS higher than 10% at initiation of dasatinib treatment, dasatinib showed better performance as a second-line therapy than as a third-line therapy. The patients who achieved an optimal molecular response at 3 months had a superior cumulative incidence of MMR and CCyR compared with patients who failed to achieve such a response. Dasatinib induced considerable responses as a second-line treatment, especially in patients with a BCR-ABL1IS ≤10% at initiation of treatment, whereas the efficacy was limited in patients receiving third-line therapy with a BCR-ABL1IS >10% at the initiation of treatment.

Steroid Refractory

Abstract Introduction Acute graft-versus-host disease (aGVHD) is a significant cause of mortality post allogeneic stem cell transplantation (SCT). First line therapy is corticosteroid based for patients with aGVHD ≥grade (Gd) II. Steroid refractory (SR) aGVHD is associated with a dismal prognosis. Although experimental therapeutics is an unmet need, there is no recent prospective real world data to establish a benchmark for outcomes of best available therapy. We undertook a prospective observational multi-centre international clinical trial of outcomes of second line therapy of steroid refractory aGVHD. The aim was to measure recently defined endpoints including Day 28 (D28) overall response rate (ORR), and 6 month freedom from treatment failure (6mFFTF; defined as a patient (pt) being alive, without relapse of underlying disease or addition of new systemic therapy for aGVHD, prior to the development of chronic(c) GVHD. Methods Data was collected prospectively in a longitudinal observational study in patients starting second line therapy for SR aGVHD. Twelve UK and 2 US sites participated. Adult pts with Gd II-IV aGVHD refractory to corticosteroids were enrolled within 5 days of starting second line therapy. Modified Glucksberg criteria were used to grade aGVHD. Expert panel consensus recommendations (Martin et al 2009) were used for complete response (CR), very good partial response (VGPR), partial response (PR), stable disease (SD) and progressive disease (PD). Kaplan-Meier survival curves and log rank tests for comparison were done on Prism7. Results Between 2014-2018, 64pts were enrolled; 4pts were excluded due to incomplete data. Baseline characteristics of the cohort are outlined in Table 1. GVHD prophylaxis varied according to centre. Forty-seven percent had T depletion; 32% ATG and 25% Alemtuzumab. GVHD was donor lymphocyte infusion (DLI) induced in 7%. At start of second line therapy,5% had Gd I, 27% Gd II and 68% Gd III-IV aGVHD. All patients had received corticosteroids at a minimum dose of 1mg/kg. Second line therapies varied, 60% received ECP and 40% non-ECP therapy including anti-TNF-alpha antibodies (20%), mycophenolate mofetil (MMF) (8%), mesenchymal stem cells (4%) and 'other' (8%). The cumulative incidence of 6mFFTF was 32% (n=19), with 68% (n=41) failing to meet the 6mFFTF endpoint. The causes of failure were, addition of third line therapy in 40% (n=24), relapse 8%(n=5), cGVHD 7% (n=4) and death 13% (n=8). The 6m incidence of death was 45% (n=27); death due to GVHD 30%, infection 8% and relapse 7%. D28 responses were: 56% ORR (8% CR, 28% VGPR, 20% PR), 13% SD, 18% PD and 13% died before D28. Using Kaplan-Meier analysis, median OS was 7.3m with a median follow up of 1 year. The overall cumulative incidence of death was 63% (n=38); GVHD was the leading cause of death 40%, infection 8% and relapse 8%. D28 ORR was associated with a significantly improved median OS not reached versus (vs) 5.2m (p=0.03) in pts who had SD or PD at D28. In pts that achieved 6mFFTF, median survival beyond 6m was not yet reached vs median survival of 3.9m in those that did not achieve 6mFFTF (p=0.0004). The trend was for a longer median OS of 8.2m in the ECP arm vs 5.3m in non ECP (p=0.79). GVHD Gd at start of second line therapy was associated with a longer median survival, not reached in Gd II cohort vs 5.7m in Gd III-IV cohort (p=0.25). Discussion Our multi-centre prospective study illustrates 'real-life' data of clinical outcomes in pts starting second line therapy for SR aGVHD. Median survival from start of second line therapy was 7.3m with a high mortality rate of 63%. D28 ORR was 56% but only 32% met the composite 6mFFTF endpoint, although both outcomes predicted survival. The leading cause for failure of 6mFFTF was starting third line therapy which may be subject to clinician bias, however the 6m mortality was 45%, thus pts went on to die after failing for another cause. This data can be used as a contemporary data while planning studies of experimental intervention vs. best available therapy. Disclosures Radia: Mallinckrodt: Research Funding.

Abstract Abstract 2274 Patients with CML in chronic phase who have failed imatinib therapy are commonly treated with dasatinib or nilotinib, but a significant proportion fail to respond or relapse in which case they are often treated with the other tyrosine kinase inhibitor (TKI) that they had not yet received. We report here the largest series of CML patients in CP treated with a third line TKI after failing both imatinib and another TKI. We enrolled 26 patients. The median age was 64 years and 54% were male. 20 patients had received dasatinib and 6 nilotinib as second line therapy. All patients were still in first CP at the moment of commencing third line therapy, and none was harboring a T315I mutation. Failure to second line therapy was defined as no CHR at 3 months, no major cytogenetic response (MCyR) at 12 months or loss of a hematological or cytogenetic response. Patients who were unable to continue therapy on account of toxicity were also considered as having failed therapy. The median follow up for the surviving patients after starting third line therapy was 21.5 months (range, 6 – 46.5 months). The 2.5 years (30 months) cumulative incidences of MCyR, CCyR and MMR were 48.2%, 32.4%, 21.1% respectively. Multivariate analysis showed that the achievement of at least MiCyR (<95% Ph-positive) on imatinib (RR=5.6, p=0.03) or on second line therapy (RR=11.8, p=0.006) were the only independent predictors for the achievement of CCyR. When combining both variables we found that patients who had achieved MiCyR on one of the two prior therapies had a significantly better OS and higher probability of achieving cytogenetic response on third line therapy, i.e. the 30 month probability of OS and CCyR were 72.7% vs 20.4% (p=0.03) and of 71.4% vs 0% (p=0.0005) respectively (Figure). During follow up 9 (34.6%) patients died. The probability of OS at 30 months was 46.7%. The achievement of a cytogenetic response on second line and age younger than 64 (possibly reflecting eligibility for transplantation) were the only independent predictors for OS (RR=6.5, p=0.02 and RR=0.13, p= 0.02). Seventeen patients (65%) were classified as intolerant to previous therapies (imatinib or second line TKI). Intolerant patients had a probability of responding to the third line therapy similar to those of the resistant patients, but when this cohort was subdivided according to the type of intolerance we found that 11 patients who had hematologic toxicity with either therapy had a probability of CCyR at 30 months lower than that of the remaining 15 patients (11.1% vs 47.5 %, p=0.03), while the 8 patients with non-hematologic intolerance to the imatinib or to the second line had a probability of 30-month CCyR greater than that of the remaining 18 patients (87.5% vs 5.6%, p<0.001). At 3 months 26 patients remained on follow up, of whom 9 patients had achieved at least MiCyR. These 9 patients had better 30-month probabilities of CCyR and OS than the patients who had failed to achieve MiCyR, namely 88.9% vs 13.3% (p<0.0001), and 87.5% vs. 35.0% (p=0.1). When we excluded the only patient who died of non-leukemia related causes while in CCyR, the probabilities of OS was 100% vs 35.0% (p=0.04) Which patients should be offered third line TKI therapy? Patients who achieved cytogenetic response on first or second line therapy and patients with a history of non-hematologic intolerance to the prior TKI benefited from a third TKI. Patients with primary cytogenetic resistance to two TKIs or with a history of hematologic intolerance should receive an allogeneic stem cell transplant when possible. For patients in this situation who lack a transplant option we would recommend only a short course (3 months) of the third line therapy to identify responders. Non-responders should be offered experimental studies. Disclosures: Marin: Bristol-Myers Squibb: Consultancy; Novartis: Consultancy, Research Funding.
