    Abstract: Deep molecular response (MR 4.5 ) defines a subgroup of patients with chronic myeloid leukemia (CML) who may stay in unmaintained remission after treatment discontinuation. It is unclear how many patients achieve MR 4.5 under different treatment modalities and whether MR 4.5 predicts survival. Patients and Methods Patients from the randomized CML-Study IV were analyzed for confirmed MR 4.5 which was defined as ≥ 4.5 log reduction of BCR-ABL on the international scale (IS) and determined by reverse transcriptase polymerase chain reaction in two consecutive analyses. Landmark analyses were performed to assess the impact of MR 4.5 on survival. Results Of 1,551 randomly assigned patients, 1,524 were assessable. After a median observation time of 67.5 months, 5-year overall survival (OS) was 90%, 5-year progression-free-survival was 87.5%, and 8-year OS was 86%. The cumulative incidence of MR 4.5 after 9 years was 70% (median, 4.9 years); confirmed MR 4.5 was 54%. MR 4.5 was reached more quickly with optimized high-dose imatinib than with imatinib 400 mg/day (P = .016). Independent of treatment approach, confirmed MR 4.5 at 4 years predicted significantly higher survival probabilities than 0.1% to 1% IS, which corresponds to complete cytogenetic remission (8-year OS, 92% v 83%; P = .047). High-dose imatinib and early major molecular remission predicted MR 4.5 . No patient with confirmed MR 4.5 has experienced progression. Conclusion MR 4.5 is a new molecular predictor of long-term outcome, is reached by a majority of patients treated with imatinib, and is achieved more quickly with optimized high-dose imatinib, which may provide an improved therapeutic basis for treatment discontinuation in CML.

    Absolute BCR-ABL Transcript Levels At 3 Months but Not At Diagnosis Predict Survival of Chronic Myeloid Leukemia (CML) Patients On Imatinib Therapy
    American Society of Hematology ; 2012

    Abstract: Abstract 3761 Introduction: Early assessment of molecular and cytogenetic response at 3 months of imatinib treatment has been shown to predict survival and might trigger treatment intensification in slow responders who are supposed to harbor a BCR-ABL positive clone with inferior susceptibility to tyrosine kinase inhibition (Hanfstein et al., Leukemia 2012). BCR-ABL transcript levels at 3 months depend on levels at diagnosis and the subsequent decline under treatment. Which of both parameters determines the clinical course and allows for prediction of survival is unclear. The BCR-ABL/ABL ratio is supposed to be skewed for high values, e.g. 〉 10%, due to the fact that ABL transcripts are also amplified from the fusion gene and in fact BCR-ABL/(ABL + BCR-ABL) is determined. Therefore, Beta-glucuronidase (GUS) was used as reference gene to determine high transcript levels at diagnosis. In addition, the linearity of the BCR-ABL/GUS scale allowed for an optimization of prognostic cut-off levels. We compared the significance of 1) BCR-ABL/GUS at diagnosis, 2) BCR-ABL/GUS at 3 months, 3) the individual reduction of transcripts given by (BCR-ABL/GUS at 3 months)/(BCR-ABL/GUS at diagnosis), and 4) the established 10% BCR-ABL/ABL landmark expressed on the international scale (BCR-ABLIS). Patients and methods: A total of 337 patients (pts) were investigated. According to the protocol of the German CML study IV pts could have been pre-treated with imatinib up to 6 weeks before randomization. 56 pts with imatinib onset before initial blood sampling within the study were excluded from the analysis. A total of 281 evaluable patients (median age 51 years, range 17–85, 42% female) were treated with an imatinib-based therapy consisting of imatinib 400 mg/d (n=76), imatinib 800 mg/d (n=110) and combinations of standard dose imatinib with interferon alpha (n=84) and low-dose cytarabine (n=11). Median follow-up was 4.8 years (range 1–10). Transcript levels of BCR-ABL, ABL, and GUS were determined by quantitative RT-PCR from samples taken before imatinib onset (“at diagnosis”) and 3 month samples. Only patients expressing typical BCR-ABL transcripts (b2a2 and/or b3a2) were considered. Disease progression was defined by the incidence of accelerated phase, blastic phase or death from any reason. A landmark analysis was performed for progression free survival (PFS) and overall survival (OS) after dichotomizing patients by a cut-off optimized by the cumulative martingale residuals method. Results: The median BCR-ABL/GUS ratio was 15.5% at diagnosis (0.07–271) and 0.62% at 3 months (0–34.7) reflecting a decline by 1.4 log. Disease progression was observed in 17 patients (6.0%), 14 of them died (5.0%). With regard to the above described parameters the following findings were observed: 1) at diagnosis no cut-off level could be identified for BCR-ABL/GUS ratios to separate two prognostic groups according to long-term PFS or OS. 2) At 3 months an optimized 2.8% BCR-ABL/GUS cut-off separated a high-risk group of 61 pts (22% of pts, 8-year PFS 78%, 8-year OS 81%) from a good-risk group of 220 pts (78% of pts, 8-year PFS 94%, 8-year OS 94%, p 〈 0.001, respectively). 3) At 3 months an individual reduction of BCR-ABL transcripts to at least 40% (0.4 log) of the initial level separated best and divided a high-risk group of 33 pts (12% of pts, 8-year PFS 74%, 8-year OS 80%) from a good-risk group of 248 pts (88% of pts, 8-year PFS 93%, 8-year OS 93%, p 〈 0.001, respectively). 4) When the established 10% BCR-ABLIS at 3 months was investigated, 63 pts were high-risk (22% of pts, 8-year PFS 82%, 8-year OS 85%) and 218 good-risk (78% of pts, 8-year PFS 91%, 8-year OS 93%, p=0.002 for PFS, p=0.011 for OS). Conclusions: Initial BCR-ABL transcript levels at diagnosis did not show prognostic significance. To predict survival at 3 months of treatment the absolute transcript level normalized by ABL or GUS can be used. Disclosures: Schnittger: MLL Munich Leukemia Laboratory: Equity Ownership.

    Abstract: Abstract 862 Rapid relapse after discontinuation of imatinib, the need for indefinite therapy and residual disease in most patients are the major challenges in management of CML. Combinations of imatinib with IFN simultaneously, or consecutively preceding imatinib, or with araC may improve treatment outcome. The German CML Study Group therefore designed a randomized trial to compare standard imatinib vs. imatinib + interferon alpha (IFN) vs. imatinib + low dose araC vs. imatinib after IFN failure (for low- and intermediate-risk patients, high risk patients received imatinib 800 mg instead). The current evaluation represents the prefinal results of the pilot phase of the trial. Inclusion criteria were newly diagnosed BCR/ABL positive CML in chronic phase (CP). Primary aims are: prolongation of survival (overall, OS, and progression free, PFS), determination of rates of hematologic, cytogenetic and molecular remissions, adverse events (AE) and role of allografting. By the end of 2005, 670 patients were randomized, 13 had to be excluded (no CML (n=3), pregnancy, no CP (n=1 each), imatinib 800 mg (n=8)). Analysis was according to intention to treat. 657 patients were evaluable (174 with imatinib 400 mg, 196 with imatinib+IFN, 158 with imatinib+araC and 129 with imatinib after IFN-failure). 656 patients were evaluable for hematologic, 611 for cytogenetic, and 618 for molecular responses. Patient characteristics of treatment arms were similar for age (median 53 years), sex (40% female), median values for Hb (12.6 g/dl), WBC (66.2/μl), platelets (383/μl) and for Euro risk score (low 35%, intermediate 54%, high 10%). The median dose of imatinib was 400mg/die in all arms, of araC 10 mg per treatment day and of IFN 4.2 Mio I.U./die in the imatinib after IFN arm and 1.8 Mio I.U./die in the imatinib+IFN arm. Median observation time was 57.3 months. 55 patients died, 73 patients were transplanted in 1st CP, 81 patients progressed, 59 patients were switched to second generation TKIs. After 3 years 126 patients (72%) of the imatinib 400mg arm still received the initial therapy as well as 60 patients (30%) of the imatinib+IFN arm and 53 patients (34%) of the imatinib+araC arm. 9 patients (7%) of the imatinib after IFN arm are still on IFN. 5-year OS of all patients is 91%. 5-year PFS of all patients (no death, patient still in first chronic phase) is 87%. 5-year-OS and PFS according to treatment arm are shown in the Table. At 5 years, the cumulative incidences of achieving complete cytogenetic remission or major molecular remission (MMR) as determined by competing risks (death, progression) are not different (Table). Type and severity of adverse events (AE) over a 5-years period did not differ from those reported previously (Table). Hematologic AEs grade III/IV were similar in all therapy arms except leukopenia grade III/IV, which was more frequently observed in the imatinib after IFN arm (14%). Non hematologic AEs were mainly fluid retention, neurological and gastrointestinal symptoms and fatigue. Neurologic symptoms and fatigue were more often reported for the therapy arms with IFN.

Currently, survival in all treatment arms is equal to, or better than in IRIS. To verify possible differences in survival, e.g. imatinib 400 mg vs. imatinib + IFN, longer observation is planned. Although cytogenetic and molecular responses in the imatinib after IFN failure arm at 5 years are inferior to that in the other treatment arms, the question of whether the consecutive therapy with IFN first and imatinib after IFN-failure provides a survival advantage requires long term follow-up. Imatinib in combination with, or after IFN, or with low dose araC are feasible and safe treatment modalities. We expect that the study will optimize and improve therapy outcome in CML.

    Abstract: Abstract 67 Dose optimized imatinib (IM) at doses of 400– 800mg has been shown to induce faster and deeper cytogenetic and molecular – responses than standard IM (400mg/day). Since complete molecular remission (CMR 4.5) identifies a subgroup of patients who may stay in remission even after discontinuation of treatment, it was of interest to analyse whether CMR 4.5 is reached faster with dose optimized IM and whether CMR 4.5 correlates with survival. CMR 4 and CMR 4.5 are defined as ≤ 0.01% BCR-ABL IS or ≥ 4. log reduction and ≤ 0.0032% BCR-ABL IS or ≥ 4.5 log reduction, respectively, from IRIS baseline as determined by real-time PCR. CML-Study IV is a five arm randomized study of IM 400 mg vs IM 400 mg + IFN vs. IM 400 mg + Ara C vs. IM after IFN failure vs. IM 800 mg. In the IM 800 arm, a 6 weeks run in period at IM 400 mg was followed by a dose increase to 800 mg and then by a dose reduction according to tolerability. Grade 3 or 4 adverse effects (AE) were to be avoided. From July 2002 to March 2012 a total of 1551 patients with newly diagnosed chronic phase CML were randomized of whom 1525 were evaluable. Median age was 52 years, 88% were EUTOS low risk, 12% high risk, 36% were Euro score low risk, 52% intermediate and 12% high risk, 38% were Sokal low risk, 38% intermediate and 24% high risk. 113 patients were transplanted, 246 received 2nd generation TKI. 152 patients have died, 90 of CML or unknown reasons, 62 of not directly CML-related causes. After a median observation time of 67,5 months 6 years OS was 88.2% and PFS 85.6%. CCR, MMR, CMR 4 and CMR 4,5 were achieved significantly faster with dose optimized IM (400 – 800 mg). No significant differences in remission rates were observed between IM 400 mg and the combination arms IM 400 mg + IFN and IM 400 mg + Ara C, whereas IM after IFN failure thus far yielded significantly slower response rates. After 4 years CCR rates were for IM 400, IM 400 + IFN, IM 400 + Ara C, IM 400 after IFN, and IM 800, 80%, 75%, 73%, 59% and 80%, respectively, MMR rates 84%, 77%, 82%, 61% and 88%, CMR 4 rates 57%, 55%, 55%, 40% and 65%, and CMR 4.5 rates 40%,42%, 42%, 28% and 52%, respectively. CMR 4 was reached after a median of 27 months with IM 800 and 41.5 months with IM 400. CMR 4.5 was reached after a median of 41.5 months with IM 800 and 63 months with IM 400. EUTOS low risk patients reached all remissions faster than EUTOS high risk patients. The differences of CMR 4 rates between IM 800 and IM 400 at 3 years were 13% and at 4 years 8%, and of CMR 4.5 rates at 3 years 10% and at 4 years 13%. Grade 3 and 4 AE were not different between IM 400 and dose optimized IM 800. Independent of treatment approach, CMR 4 and more clearly CMR 4.5 at 3 years predicted better OS and PFS, if compared with patients without CMR 4 or CMR 4.5, respectively. CMR 4 and 4.5 were stable. After a median duration of CMR 4 of 3.7 years only 4 of 792 patients with CMR 4 have progressed. Life expectancy with CMR 4 and 4.5 was identical to that of the age matched population. We conclude that dose optimized IM induces CMR 4.5 faster than IM 400 and that CMR 4 and CMR 4.5 at 3 years are associated with a survival advantage. Dose optimized IM may provide an improved therapeutic basis for unmaintained treatment discontinuation in patients with CML. Disclosures: Hehlmann: Novartis: Research Funding.

    Secondary Malignancies in CML Patients – Data From the German CML Study IV
    American Society of Hematology ; 2012

    Abstract: Abstract 3746 Introduction: The increase of overall survival in chronic myeloid leukemia (CML) requires closer long-term observation in the face of a potential carcinogenicity of tyrosine kinase inhibitors (TKIs). Preclinical studies with imatinib in rats showed neoplastic changes in kidneys, urinary bladder, urethra, preputial and clitoral glands, small intestine, parathyroid glands, adrenal glands, and nonglandular stomach. Two epidemiologic studies on patients with chronic myeloproliferative neoplasms (CMPN) and CML (Frederiksen H et al., Blood 2011; Rebora P et al., Am J Epidemiol 2010) found an increased risk of secondary malignancies compared with the general population independent of treatment. In contrast, in a recent analysis of patients with CML and CMPN treated with TKI (Verma D et al., Blood 2011) a decreased risk of secondary malignancies was reported. Aims: To further elucidate the risk of TKI treated CML patients for the development of secondary malignancies we analysed data of the CML study IV, a randomized 5-arm trial (imatinib 400 mg vs. imatinib 800 mg vs. imatinib 400 mg in combination with interferon alpha vs. imatinib 400 mg in combination with AraC vs. imatinib 400 mg after interferon failure). Patients and methods: From February 2002 to April 2012, 1551 CML patients in chronic phase were randomized, 1525 were evaluable. Inclusion criteria allowed the history of primary cancer if the disease was in stable remission. Forty-nine malignancies were reported in 43 patients before the diagnosis of CML. If relapses occurred within 5 years after diagnosis of primary cancer they were not considered for further analysis. Median follow-up was 67.5 months. Age-standardized incidence rates were calculated from the age-specific rates using the European standard population (1976). Results: In total, 67 secondary malignancies in 64 patients were found in CML patients treated with TKI (n=61) and interferon alpha only (n=3). Twelve of these patients developed neoplasms after diagnosis of a primary cancer before diagnosis of CML, 5 patients with metastases or recurrence of the first malignancy (range of diagnosis 5–19 years after primary cancer). Median time to secondary malignancy was 2.5 years (range 0.1–8.3 years). The types of neoplasms were: prostate (n=9), colorectal (n=6), lung (n=6), non Hodgkin's lymphoma (NHL; n=7), malignant melanoma (n=5), skin tumors (basalioma n=4 and squamous cell carcinoma n=1), breast (n=5), pancreas (n=4), kidney (n=4), chronic lymphocytic leukemia (n=3), head and neck (n=2), biliary (n=2), sarcoma (n=2), and esophagus, stomach, liver, vulva, uterus, brain, cancer of unknown origin (each n=1). With these numbers the age-standardized incidence rates of secondary malignancies in CML patients were calculated: 534 cases per 100,000 for men (confidence interval [350;718]), and 582 for women (confidence interval [349;817] ). The incidence rates of the general population in Germany were 450 and 350 cases, respectively (“Krebs in Deutschland 2007/2008”, 8th ed., Robert Koch Institute, 2012). The incidence rate of NHLs was higher for CML patients than for the general population but this is not significant. Conclusions: In our cohort, the incidence rate of secondary neoplasms in CML patients was slightly increased compared to the general population. The most common secondary malignancies in CML patients under treatment were cancers of the skin, prostate, colon, lung and NHL. Since the occurrence of secondary neoplasia increases over time, long-term follow-up of CML patients is warranted. Disclosures: Müller: Novartis, BMS: Consultancy, Honoraria, Research Funding.

    Abstract: Background Chronic myeloid leukemia (CML)-study IV was designed to explore whether treatment with imatinib (IM) at 400mg/day (n=400) could be optimized by doubling the dose (n=420), adding IFN (n=430) or cytarabine (n=158) or using IM after IFN-failure (n=128). Methods From July 2002 to March 2012, 1551 newly diagnosed patients in chronic phase were randomized into a 5-arm study. The study was powered to detect a survival difference of 5% at 5 years. The impact of patients' and disease factors on survival was prospectively analyzed. At the time of evaluation, at least 62% of patients still received imatinib, 26.2% were switched to 2nd generation tyrosine kinase inhibitors. Results After a median observation time of 9.5 years, 10-year overall survival was 82%, 10-year progression-free survival 80% and 10-year relative survival 92%. In spite of a faster response with IM800mg, the survival difference between IM400mg and IM800mg was only 3% at 5 years. In a multivariate analysis, the influence on survival of risk-group, major-route chromosomal aberrations, comorbidities, smoking and treatment center (academic vs. other) was significant in contrast to any form of initial treatment optimization. Patients that reached the response milestones 3, 6 and 12 months, had a significant survival advantage of about 6% after 10 years regardless of therapy. The progression probability to blast crisis was 5.8%. Blast crisis was proceeded by high-risk additional chromosomal aberrations. Conclusions For responders, monotherapy with IM400mg provides a close to normal life expectancy independent of the time to response. Survival is more determined by patients' and disease factors than by initial treatment selection. Although improvements are also needed for refractory disease and blast crisis, more life-time can currently be gained by carefully addressing non-CML determinants of survival.

    Abstract: Abstract 1681 Introduction: The prognostic impact of different levels of molecular remission (BCR-ABL transcript expression according to International Scale, IS) at various time points on survival under imatinib treatment is still unclear. Whereas recently published data from the IRIS trial described relevant milestones at 6, 12, and 18 months for event-free and progression-free survival (PFS; Hughes et al., Blood 2010), little is known about an association of molecular response with overall survival (OS). The aim of this evaluation of the German CML Study IV was to elucidate the risk of disease progression and death as a function of the depth of molecular response in order to provide guidance in the interpretation of BCR-ABL levels in the clinical setting. Methods: 1,340 patients (median age 52 years, range 16–88, 60% male) were recruited into the randomized German CML Study IV and treated with an imatinib-based therapy as follows: imatinib 400 mg/d, n=381; imatinib 800 mg/d, n=399; imatinib 400 mg/d + interferon alpha, n=402; imatinib 400 mg/d + low-dose cytarabine, n=158. A total of 1,262 patients with typical b2a2 and b3a2 BCR-ABL transcripts were evaluable. Molecular responses were assessed in 811, 764, 671, and 619 patients at 6, 12, 18, and 24 months, respectively. Disease progression was defined as accelerated phase or blastic phase, or death from any reason. Landmark analyses and log-rank tests for OS and PFS were performed according to the achievement of different BCR-ABL response levels at different time points. Results: Patients were grouped according to the degree of molecular response ( 〈 0.1%, 0.1%-1%, 1%-10%, 〉 10% BCR-ABL IS) at each of the 4 time points and evaluated for 5-year OS and PFS. Estimated 5-year OS for the different molecular response categories was: 97% vs 96% vs 90% vs 88% (6 months, p=0.009); 96% vs 95% vs 89% vs 69% (12 months, p 〈 0.001); 98% vs 97% vs 92% vs 66% (18 months, p 〈 0.001); 97% vs 96% vs 96% vs 68% (24 months, p 〈 0.001). Applying the 4 response categories revealed estimated 5-year PFS of 97% vs 96% vs 91% vs 86% (p=0.004) at 6 months, 97% vs 92% vs 89% vs 72% (p 〈 0.001) at 12 months, 99% vs 95% vs 90% vs 77% (p 〈 0.001) at 18 months, and 97% vs 97% vs 93% vs 65% (p 〈 0.001) at 24 months (s. Table). Conclusions: Faster and deeper response to imatinib-based treatment revealed to be associated with improved overall and progression-free survival. Inferior OS and PFS can be deducted from the synopsis of BCR-ABL expression and treatment duration, e.g. 〉 1% BCR-ABL IS at 6 months or 12 months might be, and 〉 10% BCR-ABL IS should be a trigger for a treatment change. Thereby this analysis might provide decision guidance for alteration or continuation of primary imatinib treatment. Disclosures: Schnittger: Münchner Leukämie Labor: Equity Ownership.
