Abstract: Background: Combination of Pegylated-Interferon alpha (Peg-IFNa) 2a and imatinib (IM) has been reported to significantly induce higher rates of molecular responses (including undetectable BCR-ABL transcript) over IM alone, as frontline therapy for CP-CML patients (pts) in a randomized phase 3 trial (SPIRIT, Preudhomme et al, NEJM 2010). Second generation TKIs such as dasatinib (DASISION, Kantarjian et al, NEJM 2010) enhance the speed and depth of molecular response (MR) in comparison to IM. Phase II trial using nilotinib and PegIFNa2a has recently reported high rates of deep molecular response (MR4.5) within 24 months (Nicolini FE et al, Lancet Haematology 2015). Aims: To determine the efficacy and safety of the combination of dasatinib and Peg-IFNa2b in CP-CML frontline. (EUDRACT Number: 2012-003389-42, Dasa-PegIFN trial). Methods: Newly diagnosed Ph+ CP-CML pts less than 65-year-old started dasatinib 100 mg/day. At 3 months, they were assigned to receive Peg-IFNa2b associated to dasatinib when platelets (plt) 〉 100 X 109/L, Neutrophils (ANC) 〉 1.5 X 109/L) and lymphocytes 〈 4.0 X 109/L counts were achieved. Otherwise, dasatinib was continued alone in the study according to the current international ELN guidelines. The maximum duration of the combination dasatinib and Peg-IFNa2b is 21 months. The primary endpoint is the cumulative rate of Molecular Response 4.5log (MR4.5 defined as BCR-ABL1/ABL1IS≤0.0032%) at 12 months. Molecular analyses were centralized and expressed according to the international scale (IS). Secondary endpoints included efficacy (cytogenetic and molecular responses at several time-points) and safety endpoints. Preliminary results are reported here. Results: 81 pts were enrolled between October 2013 and July 2014. All pts will have completed the 12 months follow-up time-point in August 2015. 79/81pts were included in the analysis (1 pt died of a CML-related haemorrhage before receiving dasatinib, 1 screening failure (masked Ph)). Median age was 48 (20-65) years. 54% of pts were male. Sokal scores were low, intermediate and high in 51%, 32% and 17% of pts respectively. After the first 3 months of therapy (M3), sixty-one patients (77%) started Peg-IFNa2b at the dose of 30 microg/week in association with dasatinib. For these pts after M3, reported hematologic adverse events (AE) were neutropenia (G3/4 n=11; G1/2 n=17), thrombocytopenia (G3/4 n=0; G1/2 n=7), anemia (G3/4 n=0; G1/2 n=7). Extra-hematologic AE were essentially of low grade (overall, G3/4 n=3; G1/2 n=113). According to NCI CTCAE V4.0, most frequent AE were infections (16%), general symptoms (15%), skin lesions (10%), hepato-biliary abnormalities (7.7%), nervous system/headache (7.7%) musculoskeletal pain (7%), psychiatric (7%), GI (6%) disorders. Eight serious AE (SAE) were reported after Peg-IFNa2b initiation: G4 neutropenia n=2, dysthyroitidis n=1, dyspnea n=1, pleural effusion n=1, lymphoid hyperplasia n=1, hemorrhoids n=1, rectal fistula (SUSAR) n=1. Efficacy was analysed according to the intention-to-treat principle (ITT), and considering missing data as no response to avoid inflated results. Overall at M3, 85% of pts had a BCR-ABL1/ABL1 ratio ≤10%. For eligible patients who received combined therapy (n=61), rates of MMR were 16%, 51%, 70%, and 70% (pending n=5) at M3, M6, M9 and M12, including MR4.5 rates 10%, 20%, 30% at M6, M9 and M12 respectively. Eighteen pts (22.7%) were not eligible to receive Peg-IFNa2b. Reasons, according to protocol criteria, were ANC 〈 1.5 X 109/L (n=10), plt 〈 100.0 X 109/L (n=5), lymphocytes 〉 4.0 X 109/L (n=1), absence of complete hematologic response (n=1), non compliance (n=1). Rates of MMR for these pts were 27% at M6, 50 % at M9 (missing n=2), pending data for n=6 at M12. Conclusion: Peg-IFNa2b combined to dasatinib therapy in first line CP-CML induces a high rate of deep molecular response (ie MR4.5) during the first year of therapy. Despite few pending data, results at 12 months are already in line with previous data combining Peg-IFNa and TKI, expecting a potential for an increased rate in therapy cessation attempt. Preliminary data of this phase II trial indicate a manageable toxicity profile for this combination, despite an increased rate of neutropenia. Updated analyses (ITT and per protocol) will be presented for all the pts with at least 12 months follow-up.

Abstract: Chronic myeloid leukemia (CML) is a myeloproliferative disorder with a median age of approximately 60 years (Hoglund M 2013). However, little is known about outcomes in CML in adolescents and young adults. In the literature there are few reports involving only patients enrolled in trials aged from 15 to 30 years (Cortes J 2012, Kalmanti L 2013). We report here the characteristics and outcomes in 78 unselected adolescents and young adults ranging from 18 to 25 years with newly diagnosed CML in chronic (n=73) or in accelerated phase (n=5) in the tyrosine kinase inhibitor (TKI) era from 13 Fi-LMC centers being in possession with local databases. The median follow-up is 56 months (0-144) after diagnosis. Sokal scores were low in 41 (56%) patients, intermediate in 10 (13%), and high in 13 (17%) and unknown in 9 (14%) patients. Five patients had a CCA/Ph+ but were in CP cytologically, at diagnosis. Initial TKI were imatinib alone (n=55) or in combination with IFN (n=3), nilotinib alone (n=5) or in combination (n=1), dasatinib alone (n=10) or in combination (n=1) or ponatinib (n=1). One patient died before treatment initiation from brain hemorrhage, and initial treatment is unknown in one patient. Only 38/76 (50%) of patients remained under TKI first-line at latest follow-up. The reasons of first-line discontinuation were blast crisis (n=3); according to ELN criteria, cytogenetic failures (n=10), molecular failures (n=5), molecular warnings (n=8), mutation (n=1); intolerance (n=6), FDA notification in EPIC study (n=1). The second-line therapies were imatinib (n=2), IFN in combination with aracytine (n=1), nilotinib (n=13), dasatinib (n=13), high-dose chemotherapy alone (n=1) or followed by allogeneic bone marrow transplantation (n=4). 13 patients discontinued their second line TKI for blastic transformations (n=2), cytogenetic failures (n=4), molecular failures (n=2), molecular warning (n=1), mutation (n=1) and intolerance (n=3). The third-line therapies were imatinib (n=1), nilotinib (n=2), dasatinib (n=5), ponatinib (n=1), chemotherapy alone (n=1), allo-transplantation (n=1). Only 25/78 (32%) of patients were included in a trial. Only one patient experimented a 4th line of TKI (ponatinib). We compared characteristics and outcome of the 2 groups of patients, enrolled in first line versus unenrolled (Table 1). There were significantly more men included than women. Accelerated phases and CCA/Ph+ were observed only in the unenrolled group. The overall survival is shown in Figure 1A. Blastic transformation, failure of TKI defined as ELN 2013 recommendations and death were used to calculate the EFS curve (Figure 1B). Finally, we designed a curve representing the probability to remain under first-line TKI: 2nd line TKI-Free Survival (Figure 1C). A complete analysis comparing characteristics and outcome between the 2 groups of patients, will be available for ASH presentation.

Abstract: The French group, GOELAMS, performed a multicenter phase III randomized open trial to evaluate whether adding androgens to post-remission induction therapy was associated with an improved outcome in elderly pts with de novo AML. All patients received the ICL induction protocol (idarubicin 8mg/m2 day1–5, cytarabine 100mg/m2 day1–7 & lomustine 200mg/m2 day1). Patients in complete or partial remission received maintenance therapy consisting in 6 reinduction courses (idarubicin 8mg/m2 day1, cytarabine 100mg/m2 day1–5.), once every 3 months, with a continuous regimen of methotrexate and 6-mercaptopurine in-between these. At diagnosis, patients were randomized to receive (AndroG arm) or not (Control arm) norethandrolone 10 to 20 mg per day, according to body weight. Androgen was started after recovery from aplasia, between day-20 and day-30 following induction chemotherapy, and was to be continued during the 2-year maintenance therapy period if a complete or partial remission was achieved following induction chemotherapy. The two arms were well-balanced for known prognostic factors. Between June 2002 and January 2005, 330 patients with de novo AML and age 60 y (median 70, range 60–86) were included. Pts with acute promyelocytic leukemia were not included. At diagnosis, ECOG was 0–1, 2, 3–4 in 270, 55, and 5 cases; WBC count was & lt; 4 G/L, & gt; 30 G/L, & gt; 100 G/L in 141, 85, and 33 pts. Of note, 61% of the pts with a WBC count & lt; 4 G/L were males, and 52% of males had a low WBC count vs 33% of females (p & lt;0.001). Centrally reviewed cytogenetics was available in 308 cases (high-risk, 78; int-risk, 185; low-risk, 15; failures, 30). Median follow-up from induction chemotherapy was 1.1 y (1st quartile, 0.34 y; 3rd quartile, 2.91 y) for the overall group, and 3.6 y (1st quartile, 3.2 y; 3rd quartile, 4.3 y) for pts alive at last news. Complete remission, on days 40 and 80, was achieved by 56% vs 52%, and 83% vs 79% of the pts in Control and AndroG arms, respectively. Twelve pts from the AndroG arm did not receive norethandrolone. Fine & Gray competing-risk model was used to estimate 5-year relapse incidence and the effect of norethandrolone on this endpoint. As for relapse, the potential benefit of norethandrolone on 5-year leukemia-free survival (LFS), event-free survival (EFS), and overall survival (OS) was analyzed on an intention-to-treat basis, using univariate and multivariate adjusted models. S-Plus2000Pro software was used for all analyses. Results: Crude univariate analyses regarding the effect of androgen randomization on 5-year relapse incidence, LFS, EFS and OS are listed in Table 1. Table 1 Full time period from diagnosis HR, hazard ratio; CI, confidence interval; Cox p-val, p-value of Cox regression model. Endpoints Control AndroG Gray test p-val HR; 95%CI Cox p-val Relapse 66% 54% 0.21 -- -- LFS 23% 33% -- 0.79; 0.58–1.09 0.15 EFS 16% 22% -- 0.95; 0.75–1.22 0.69 OS 19% 26% -- 0.96; 0.74–1.23 0.72 Of note, the effect of norethandrolone on relapse incidence, LFS, EFS, and OS, was violating the proportional hazards assumption (scaled Schoenfeld residuals analysis). Since the 2 hazards rate functions crossed each other, which would result in ineffective comparisons if using log-rank tests, time-dependent models were considered. For all these endpoints, as estimates for the 2 arms were not significantly different during the first year, but diverged during the following years, favoring the AndroG arm (Table 2, Figure 1), a step-function at 1 year from diagnosis was considered. Table 2 Time period starting 1 year from diagnosis Endpoints Control AndroG Gray test p-val HR; 95%CI Cox p-val Relapse 55% 33% & lt; 0.01 -- -- LFS 37% 54% -- 0.56; 0.33–0.94 0.028 EFS 32% 52% -- 0.57; 0.36–0.89 0.013 OS 37% 60% -- 0.63; 0.41–0.96 0.034 Figure Figure Thus, for pts alive and in complete remission at 1 year from diagnosis, relapse incidence was lower, while LFS, EFS and OS were higher in the AndroG arm, even after adjusting for other significant covariates (p=0.029 Relapse; p=0.038 LFS; p=0.028 EFS; p=0.029 OS). Moreover, the beneficial effect of norethandrolone was more pronounced in males, and in pts having WBC count & lt; 4 G/L as shown in Figure 2 for the LFS. Figure Figure Conclusion: addition of low-dose norethandrolone to maintenance chemotherapy is associated with an improved outcome in elderly pts with AML; especially in those achieving CR and remaining in remission for at least a year. Improved outcome was observed with androgen in males and/or in pts with low proliferative disease.

Abstract: Context: The Tyrosine Kinase Inhibitors (TKIs) have revolutionized the treatment of chronic myeloid leukemia (CML) increasing dramatically the survival of CML patients and leading to a residual disease with a sustained and deep molecular response. In this subset of very good responder patients, the attempts of stopping treatment in different clinical trials were successfully achieved without relapse. The Swedish team in the EURO-SKI protocol already reported cases of musculoskeletal pain occurring after cessation of TKI (Richter et al., JCO, 2014). Since several clinical trials regarding TKI discontinuation have been also run in France, we decided to retrospectively collect data using the pharmacovigilance system of the different Trials collected prospectively. Method: 428 patients from STIM2 (n=204) and EURO-SKI (n=224) trials were systematically analyzed from the case report from each trial. For the EURO-SKI only French patients were included. Statistical analysis was performed using Stata 13 software (StataCorp LP, College Station, TX, US). Comparisons between the independent groups were realized using the Chi-squared or Fisher's exact tests for categorical variables, and using Student t-test or Mann-Whitney test for quantitative. Multivariate analyses were performed to take into account adjustment on covariates fixed according to univariate results and clinically relevance. Results: Among the 428 patients the main characteristics were as follow i,e; 208 (48.6%) men and 220 (51.4%) women, with a median age of 77.5 years (24-93). Sokal scores (n=449) were low in 187 (41.6%) patients, intermediate in 188 (41.9%) patients and high in 74 (16.5%) patients. A withdrawal TKI syndrome (WS) was reported for 102 (23.8%) patients (100 after imatinib and 2 after nilotinib). 2). The WS consists in bone and articular pains and arthritis and affects the upper limbs, shoulders and cervical rachis, with a grade 1 or 2 in most patients and grade 3 in 22% of patients . The prevalence of WS depends on the trials, 34.8% in EURO-SKI group and 13.8% in STIM2 group (p 〈 0.001). The WS was treated by non-steroidal anti-inflammatory drugs, corticosteroids or by local infiltration. The median duration of WS was 7 months (range: 3-30 months, 24 exploitable cases). We did not observe any difference between WS group and the group without painful syndrome in terms of sex ratio (p=0.92), age (p=0.33), sokal score (p=0.15), BCR-ABL transcript (p=0.42) or duration of CML (p=0.24). However the median duration of TKI therapy appeared longer in this subgroup (median: 88.8 months vs 79.8 months (p=0.02). There was no biological inflammatory syndrome and the results of medical imaging were inconclusive. However, a medical history of osteoarticular pains or disease appeared as predisposing to withdrawal syndrome (22.9% in WS group vs 9.8% in control group; p=0.002). Finally the two factors, duration of treatment and medical history were confirmed using multivariate analysis (RR=1.73 and 1.76 respectively). Among 19 exploitable cases suffering CML relapse and requiring further TKI treatment, pain disappeared in 7 patients (37%) within a median period of 3.5 weeks. Conclusion: About 23% of patients who stopped TKIs experienced a TKI WS and all TKI seems to be concerned. The predisposing factors were a medical history of osteoarticular pain or disease, and the duration of treatment. So patients and physicians should be aware and recommendations should be proposed for patients who have treated longtime with a history of arthritis.

Abstract: Tyrosine kinase inhibitor (TKI) discontinuation is an emerging goal in chronic myelogenous leukemia (CML) management and several studies have demonstrated the feasibility of safely stopping imatinib. A sustained deep molecular response on long-term TKI is critical prior to attempting treatment-free remission. Reproducible results from several studies reported recently, failed to identify robust and reproducible predictive factors for the selection of the best candidates for successful TKI cessation. Patients and Methods: We conducted a prospective national phase II study evaluating the cessation of imatinib after at least 2 years of MR4.5 obtained on imatinib first-line in patients with chronic phase CML. Results: A total of 218 patients with de novo chronic phase CML were involved in the study. The median follow-up after imatinib cessation was 23.5 (1–64) months, 2 patients died from unrelated causes, and 107 experienced a confirmed increase in BCR-ABL1 levels defined as molecular recurrence. The molecular recurrence-free survival was 52% [95% confidence interval (CI), 45%–59%] at 6 months, and 50% (95% CI, 43%–57%) at 24 months. Droplet digital PCR (ddPCR) was used to evaluate more accurately low levels of BCR-ABL1 in 175 of 218 patients at imatinib cessation. To apply positive BCR-ABL1/ABL1 ratios on the international scale (IS), a conversion factor was calculated for ddPCR and the significant cut-off point was established at 0.0023%IS. In a multivariate analysis, the duration of TKI (≥74.8 months) and ddPCR (≥0.0023%IS) were the two identified predictive factors of molecular recurrence, with P = 0.0366 (HR, 0.635; 95% CI, 0.415–0.972] and P = 0.008 (HR, 0.556; 95% CI, 0.360–0.858), respectively. Conclusions: We conclude that the duration of TKI and residual leukemic cell load as determined by ddPCR are key factors for predicting successful treatment-free remission for patients with de novo chronic phase CML.

Abstract: Clinical trials have demonstrated that patients with chronic‐phase chronic myeloid leukemia with deep and durable molecular responses can attempt to stop using tyrosine kinase inhibitors. The French Chronic Myeloid Leukemia Study Group (France Intergroupe des Leucémies Myéloïdes Chroniques) has developed recommendations for tyrosine kinase inhibitor discontinuation in daily practice.

Abstract: Treatment of primary central nervous system lymphoma (PCNSL) in elderly patients remains unsatisfactory. To develop a new high‐dose methotrexate (HD‐MTX)‐based regimen including idarubicin, a phase 1 multicenter dose escalation study was conducted to determine the maximum‐tolerated dose (MTD) of idarubicin. Thirty‐five immunocompetent patients with PCNSL were enrolled. The median age was 65 years (range, 60–70 years). MTX and vindesine (VDS) were given at the fixed dose of 3 g/m 2 (6‐hr intravenous [IV]) and 3 mg/m 2 IV on day 1, respectively. Prednisolone (PRED) was given at the fixed dose of 60 mg/m 2 (IV or orally) on days 1–5. Idarubicin was escalated in increments of 2 mg/m 2 with doses ranging from 12–18 mg/m 2 IV on day 1. Treatment was repeated three times every 3 weeks. Dose‐limiting toxicity (DLT) was defined as grade 4 neutropenia for more than 7 days, thrombocytopenia grade 4 or nonhaematological toxicity more than grade 2. The MTD of idarubicin was reached at 16 mg/m 2 . At this level, the main haematological toxicities were thrombocytopenia grade 4: 5% and neutropenia grade 3 or 4 (52%); the main nonhaematological toxicities were grade 3 or 4 infectious disease (5%) and grade 2 renal failure (9%). For the study population, median overall and progression‐free survival were 19 and 13 months, respectively. Our study suggests that the MTD of idarubicin in combination with HD‐MTX, VDS, and PRED, should be 16 mg/m 2 . Further studies will be necessary to challenge a standard treatment in elderly patients with PCNSL. Am. J. Hematol. 89:1024–1029, 2014. © 2014 Wiley Periodicals, Inc.
