Abstract Abstract 879 As previously reported, dose-escalated first-line therapy with autoSCT as conducted in the GCLLSG CLL3 protocol is a feasible and effective therapy option for younger patients with poor-risk CLL. Purpose of the present analysis was to study the impact of FISH karyotype according to the hierarchical model, and of IGHV mutational status on progression-free (PFS) and overall survival (OS) in this trial. Trial design and patients: The protocol comprised optional cytoreduction with CHOP, fludarabine, or FC; PBSC mobilization using the Dexa-BEAM regimen; and myeloablative therapy with TBI/CY followed by reinfusion of purged (CD34+) stem cells. Inclusion criteria were age <61 years, stage Binet B/C or poor-risk stage A as defined by short lymphocyte doubling time plus elevated TK, and one line of pretreatment or less. From December 1996 through September 2002, 216 patients were registered with the protocol. As 47 cases had to be excluded due to screening failure (n=21), withdrawn consent (n=19) or other reasons (n=7), 169 patients were eligible for the current analysis. Male to female ratio was 5:1 and the median age at diagnosis was 51 years (range 27-60). Results: SCT was performed in 131 patients (78%) at a median time of 17 months (range 4-159) after initial diagnosis, whereas 38 patients did not proceed to SCT due to mobilization failure (n=14), disease progression (n=4), early death (n=3), patients preference (n=6), or unknown reasons (n=11). At a median follow-up of 99 months (range 4-137) after initiation of first cytoreductive therapy within the protocol, median OS of all 169 patients was 10.5 years, with 10.5 years for those treated with and 6.1 years for those treated without autoSCT, yielding a hazard ratio of 0.26 (95% CI 0.13-0.54; p<.0001). Median PFS was 6.3 years, with 6.8 years for those treated with and 4.8 years for those treated without autoSCT (HR 0.39; 95% CI 0.23-0.67; p=0.0007). The 10-year incidence rate of t-MDS/ t-AML was 9% (1-18%). Diagnostic samples for assessment of the IGHV mutational status were available for 143 of 169 patients (85%). An unfavorable (unmutated of V3-21-containing) IGHV rearrangement was present in 104 patients (73%). Compared to the 39 patients with favorable IGHV, those with unfavorable VH had significantly worse PFS and OS (median PFS 5.1 years vs not reached, hazard ratio (HR) 2.47 (1.56-3.92), p=0.0001; median OS 9.1 years vs not reached, HR 2.0 (1.14-3.68), p=0.017). FISH was possible in 160 patients (95%) with results as follows: del 17p- 4 patients (3%), del 11q- without del 17p 40 patients (25%), trisomy 12 without del 17p- and del 11q- 20 patients (13%), del 13q- as sole abnormality 48 patients (30%), other karyotypes 20 patients (13%), normal karyotype 28 patients (17%). All 4 patients with del 17p- showed progressive disease after Dexa-BEAM mobilization and did not proceed to autoSCT. Whereas PFS (p <0.0001) and OS (p <0.0001) thus was strongly reduced in the 4 patients with del 17p-, no significant differences between the other subsets became evident: median PFS 1.0 years (del 17p-), 5.9 years (del 11q), 4.8 years (+12), 7.5 years (del 13q-), 7.7 years (normal); median OS 1.5 years (del 17p-), 10.5 years (del 11q-), not reached (+12), not reached (del 13q-), 10.3 years (normal). Conclusions: Unmutated IGHV remains an adverse prognostic factor after dose-escalated first-line therapy with autoSCT. In contrast, this strategy may overcome the unfavorable impact of the FISH karyotype del 11q- seen with conventional therapy. Disclosures: Hopfinger: Roche: Honoraria.

Abstract Background. Rapid advances in clinical discovery and availability of new treatment options have increased the complexity of treatment decisions for patients with CLL. Guidelines list multiple agents and combinations as recommended therapeutic options for CLL but often do not provide specific treatment recommendations for individual patients. We developed an online treatment decision tool that provides treatment recommendations from CLL experts for specific patient cases. We hypothesized that these individualized recommendations from recognized experts would affect treatment plans. Here we report on an analysis of data entered into this CLL decision support tool, including variance between intended treatment of tool users and the recommendations made by the experts and the impact of the tool on subsequent therapy decisions. Methods. In December 2015, 5 experts provided treatment recommendations for 1380 case variations based on key factors that guide treatment choice. Expert-selected factors for newly diagnosed CLL included age, fitness (based on ECOG PS, CIRS, and renal function), and cytogenetic abnormalities (del[17p], del[11q], or other). Additional variables for patients with relapsed/refractory (R/R) disease after first-line treatment included previous treatment, response duration, and burden of comorbidities. To use the tool, drop-down menus allowed users to select from choices for each variable and their intended treatment for that patient. The corresponding treatment selection from 5 experts was then displayed and users were asked about the tool's impact on their planned treatment. Results. An analysis of 883 patient scenarios (67% treatment naive and 33% with R/R CLL) entered into the tool from February 2016 through July 2016 found substantial variation between the intended therapy choice among tool users and the recommendations from the experts.For example, in every patient case with del(17p), all 5 of the experts recommended ibrutinib as first-line therapy whereas only 49% of tool users planned to use ibrutinib for these patients. Of those users whose intended first-line therapy for del(17p) CLL did not match the experts' recommendation, 54% indicated that this tool would change their original treatment plan and 17% indicated a barrier to implementing this treatment. For either elderly or unfit patients without del(17p), 4 of 5 experts recommended obinutuzumab plus chlorambucil, but only 41% of tool users planned to use this regimen with 50% citing barriers to this treatment approach. For patients with del(17p) CLL and disease relapse or recurrence after chemoimmunotherapy, all 5 experts recommended ibrutinib for these cases with the exception of patients with a history of atrial fibrillation, anticoagulation, or difficult-to-control hypertension where 4 of 5 experts recommended idelalisib/rituximab. Again, the intended treatment plan of approximately 50% of tool users failed to match the experts' recommendation for these cases, and half of these users indicated that this tool would change their original treatment plan. At the time of tool development, all experts recommended either idelalisib/rituximab or clinical trial for patients with R/R CLL and del(17p) who previously received ibrutinib, but 61% of users indicated that they were unsure of the next appropriate treatment. All users who answered the impact question indicated that they now intended to use the expert-recommended treatment for these patients. For patients without del(17p) cytogenetics, treatment selection was more variable among experts and users and changed based on age, fitness, and previous therapy. For patients with del(11q) or other cytogenetics, approximately 20% of tool users were unsure of the appropriate treatment after progression on first-line therapy but 71% of those who answered the impact questions indicated that they remained unsure of their treatment approach despite viewing expert recommendations. Conclusions. Our analysis demonstrates that this interactive online therapy decision tool providing expert recommendations for specific case scenarios in CLL can support optimal decision making and change intended treatment for a majority of cases in which the planned therapy differed from the experts. Detailed comparisons of expert and user responses from the online tool will be presented.

Abstract Abstract 3926 Introduction. Chronic lymphocytic leukemia (CLL) patients will have significant variation in signs and symptoms at initial presentation and across lines of therapy, with concomitant effect on patient health-related quality of life (HRQOL). HRQOL and other patient-reported outcomes, together with clinical outcomes, provide a more complete perspective on the burden of disease and facilitate a broader view of the impact of treatment regimens. This analysis evaluates whether the HRQOL of patients with CLL in the United States (US) varies at the time the patients are about to embark on various lines of therapy, and offers a baseline report from which subsequent longitudinal analysis post-treatment will be possible. Methods. Clinical and HRQOL data were collected in Connect®CLL, a prospective observational registry initiated in March 2010 involving centers in the US. Physicians provided data on the demographics and clinical characteristics of patients receiving therapy. HRQOL was self-reported by patients at enrollment using the Brief Fatigue Inventory (BFI, a symptom assessment tool), the EQ-5D (a non-disease-specific HRQOL instrument), and the Functional Assessment of Cancer Therapy-Leukemia (FACT-Leu, a leukemia-specific HRQOL instrument). We characterized patients who had initial (First Line), second (Second Line) or subsequent (Higher Line) treatment regimens prior to initiation of regimens. Reported mean overall and/or domain-specific BFI, EQ-5D and FACT-Leu scores were analyzed by line of therapy. Statistical significance of score differences among sub-cohorts was ascertained by ANOVA using SAS 9.1. Results. Evaluable data were reported on 1005 patients, enrolled from 161 centers (93% community, 7% academic). Patients were predominantly male (62%) and white (89%) with mean age at 69 (standard deviation [SD] 11) years. HRQOL scores by line of therapy are presented: The total FACT-Leu and FACT-G results, and the total EQ-5D Index and Visual Analogue Scale (VAS) results, consistently suggest that patients initiating first line therapy have somewhat better HRQOL compared with those initiating subsequent lines of therapy. FACT-Leu total scores of patients initiating first line therapy were associated with better physical and leukemia-specific considerations, and the EQ-5D total score was associated with better mobility and pain/discomfort. Conclusions. Initial results from the Connect® CLL Registry indicate that HRQOL prior to treatment is better among patients initiating first line therapy compared to patients initiating later lines of treatment. Future analyses should be conducted to determine what clinical or other factors may be associated with the HRQOL deterioration in patients initiating subsequent lines of therapy, so as to inform clinician decision making. Also, subsequent longitudinal analyses should be undertaken to determine how HRQOL might be affected by the different lines of therapy and the specific treatment regimens, as well as by their initial HRQOL and other patient factors.

Introduction: NLR combines a marker of inflammation (neutrophilia) and immune senescence (lymphopenia) to reflect aging related alterations in the immune systems. Prior studies have shown that NLR can serve as a marker of frailty and predict survival among older adults with solid tumors and lymphomas, its role among older adults with MM remains unclear. Methods: We used the Flatiron Health electronic health record-derived de-identified database to source older adults (age ≥60y) with incident MM diagnosed between 1/1/2011 and 2/1/2020. We limited our study cohort with known first line therapy and absolute neutrophil and lymphocyte count (cells//µL) up to 90 days before the start of treatment. We constructed a modified frailty index (Facon et al Leukemia 2020) at MM diagnosis combining age, comorbidity and ECOG performance status, captured within 90 days from the start of first line therapy categorizing patients into frail vs nonfrail. We examined the association between NLR (stratified into quartiles, Q1-Q4) and frailty using logistic regression model adjusted for age, sex and race/ethnicity. We used Kaplan Meier methods and multivariable Cox regression to assess the impact of NLR on overall survival adjusting for age, sex, race/ethnicity, international staging system (ISS) stage, high-risk cytogenetics (HRCA; del17p, t4;14 or t14;16), and first-line therapy. Results: Of 2792 eligible patients, the median age at MM diagnosis was 73y (IQR: 67-78y), with 53% males and 61% non-Hispanic whites. Of these, 56% had IgG isotype, 22% ISS stage-III and 13% had HRCA. The median NLR was 2.29 (IQR: 1.5 to 3.59). Of the 1,743 evaluable for frailty, 1042 patients (59.8%) were frail. Overall, 45% received proteasome inhibitor (PI) + Immunomodulatory agent (Imid) based first line therapy and 19% received autologous stem cell transplantation. Patients in the highest NLR quartile were at a 2.1-fold higher odds of being frail (95% CI 1.52-2.86; p &lt;0.001) when compared with those in the lowest NLR quartile (after adjusting for age, sex and race/ethnicity). NLR was poorly correlated with age (Pearson's r= 0.02). Patients in the highest NLR quartile had an inferior overall survival vs those in the lowest quartile (median OS/3y-OS in Q4 3.3y/53% vs 4.7y/69% in Q1; log-rank p &lt;0.01). Similar results were seen when limiting to patients receiving first line PI & Imid triplet and PI or Imid based doublet regimens (Fig 1). In a multivariable analysis, patients in the highest NLR quartile had a 1.5 times increased hazards of death (95% CI 1.28-1.85, p &lt;0.001) when compared with those in the lowest NLR quartile, after adjusting for potential confounders (Table 1). Conclusion: NLR is an easily available laboratory biomarker associated with frailty as well as inferior overall survival among older adults with MM. Future studies should explore its value as a screening tool to identify frail older adults with MM and guide appropriate treatment selection and targeted interventions to prevent excess toxicities and improve outcomes.

Aim. To evaluate the efficacy and safety of the BR regimen containing bendamustine in patients with chronic lymphocytic leukemia (CLL) who have not previously received specific therapy. Subjects and methods. The results of the Russian prospective observational multicenter study BEN-001 (2012—2015) covering 196 CLL patients from 34 centers of the Russian Federation were analyzed. The diagnosis was confirmed by the results of peripheral blood lymphocyte immunophenotyping. A centralized approach was employed to make IGHV gene mutational status analysis, FISH examination, and minimal residual disease according to standardized methods. Quality-of-life (QOL) indicators were estimated using the EQ-5D and FACT-Leu questionnaires. Survival rates were calculated applying by the Kaplan-Meier method. Results. The patients’ median age was 61 years. 41% of patients had a decline in estimated creatinine clearance less than 70 ml/min/1.73 m2. The combination of bendamustine and rituximab could achieve a common response in 83.2% of the patients, including complete remission in 59.7%. Eradication of minimal residual disease was achieved in 23 (27.4%) of 84 patients. Two-year progression-free survival rates were 85.9%. The QOL indicators were noted to be improved during the treatment. Conclusion. The investigation shows the good tolerability of bendamustine when it is used in clinical practice. Due to the high cost of new drugs (ibrutinib, obinutuzumab, ofatumumab, etc.) and toxicity of the FCR regimen, the combination including bendamustine can be the best first-line therapy option for all CLL patients, regardless of their age and comorbidity.

Abstract Introduction: Clinical availability of highly effective novel agents (including Bruton tyrosine kinase [BTK] and B-cell lymphoma 2 [BCL-2] inhibitors) is rapidly altering the therapeutic landscape of chronic lymphocytic leukemia (CLL) necessitating a review of treatment guidelines. However, there is limited real-world data to validate if the availability of these novel agents has translated to a true shift in treatment paradigm for patients treated in the community. As the majority of CLL patients are treated in non-academic community-based settings, we investigated the clinical adoption trends of commercially available FDA approved novel agents for treatment of CLL patients. In addition, given that the COVID-19 pandemic led to major alteration in clinical oncology practices, we further studied if this contributed to an alteration in the selection of therapeutic agents resulting in changes of CLL treatment patterns and the utilization of novel agents in the real-world setting. Thus, the objectives of this study were to examine the utilization pattern of various CLL therapies, as well as evaluate the pattern of adoption of novel agents for treatment and the impact of COVID. Methods: A retrospective observational study was conducted using the Flatiron Health database that comprised EHR-derived de-identified data. Adult patients (≥18 years) with newly diagnosed CLL from January 2014 to May 2021, with no prior treatment and who were continuously enrolled for at least 6 months before and 3 months after the index date, defined as the first date of CLL/SLL diagnosis were included. Treatment regimens were classified into seven mutually exclusive categories: bendamustine-based chemotherapy, other chemotherapy, anti-CD20-based therapy, ibrutinib, idelalisib, acalabrutinib and venetoclax. Further treatment categorization included chemotherapy vs. targeted therapy, and traditional IV vs. novel oral agents. The impact of the pandemic was examined by comparing the pre- and post-COVID cohorts (defined as 15 months pre- and post- of March 1, 2021). Descriptive analyses were conducted to examine the frequency of use of treatment regimens by quarter in each year, line of therapy and between different age, gender, US geographical region, insurance status, and race/ethnicity subgroups. Multivariable regression was conducted to examine factors associated with the likelihood of adoption of novel and oral agents. Statistical significance was determined at a p-value of less than 0.05. Results: A total of 3,037 newly diagnosed CLL patients (median age =73) were included in the study. Over half were male (62.3%), white (74.6%) and commercially-insured (54.1%). Patients were primarily treated in community practices (92%). Overall, a significant trend in adoption of novel agents was observed throughout the years following their approval (Figure 1A). Across the evaluation period, a significant decrease in chemotherapy use was observed from 61.3% (quarter 1, 2014) to 20% (quarter 2, 2021) in favor of targeted therapy as first-line therapy (Figure 1B). In contrast, the utilization of novel oral agents (vs. traditional IV agents) for first-line therapy increased from 9.5% to 70.9% for the same period (Figure 1C). Similar trends were observed for second-line and third-line therapies. Encouragingly, this change in treatment patterns was adopted comparably in all sociodemographic subgroups with no evidence of disparity. While there was no statistically significant difference between the pre- and post-COVID treatment landscape, the adoption of target and novel oral agents has been more pronounced with the COVID pandemic. Conclusions: Results from real-world data suggest that there is a clear shift towards the adoption of novel therapies with preference given to targeted agents and oral therapies in the US since 2014. Further research examining real-world outcomes associated with treatment regimens are needed to inform decision makers. Figure 1 Figure 1.

Background: Oral fludarabine and intravenous rituximab (FR) was the standard first-line therapy for CLL or small lymphocytic lymphoma (SLL) patients (pts) in BC from 2003-2015. Ibrutinib for relapsed/refractory (R/R) CLL was introduced and publicly funded in 2015. Our aim was to review long term outcomes of all CLL/SLL pts treated with FR in BC, including the impact of 2nd line therapy with ibrutinib versus chemoimmunotherapy and to report the risk of secondary malignancies in this population based cohort. Methods: The BC Provincial CLL Database was used to identify all CLL/SLL pts who received first-line FR from 2003-2017. The BC Cancer Registry was used to identify secondary malignancies occurring after FR. Primary outcomes were overall survival (OS) and treatment free survival (TFS), defined as start of FR to next-line therapy or death/last follow-up. Variables examined for impact on OS/TFS included age at FR, gender, primary diagnosis (CLL vs SLL), B symptoms, advanced stage (Rai stage 3-4 CLL, Ann Arbor 1-2 SLL), baseline hemoglobin, lymphocyte count, platelets, LDH and FISH abnormalities. All variables significant on univariate analyses (P<.1) were included in multivariate Cox proportional hazard regression models to identify significant predictors of OS/TFS. Results: 673 pts were identified as receiving FR as first-line therapy for CLL (86%) or SLL (14%). Median time from CLL/SLL diagnosis to FR was 2.5 years (y) (range 0.1-27.3). Median age at FR was 67 y (range 26-91) with 73% ≥ 60 y and 39% ≥ 70 y. Most pts were male (66.1%), had early stage disease (84.2%) with no B symptoms (89.7%) and normal LDH (81.1%). Of 411 pts with pre-treatment FISH testing, prevalence of FISH abnormalities were: 48.5% del13q, 25.7% trisomy 12, 12.9% del11q, 8.0% del17p. Median number of FR cycles was 6 (range 1-10). Median follow-up of living pts from FR was 6.4 y (range 0.2-12.7). 2 y and 5 y OS were 89.4% (95% CI: 86.8-91.6) and 73% (95% CI: 69.0-76.6) respectively; median OS 11.6 y (95% CI: 4.6-13.7 y). 2 y and 5 y TFS were 72% (95% CI: 68-75%) and 37% (95% CI: 33 - 41) respectively, median TFS 3.8 y (95% CI: 1.78-7.09). Those with del17p had significantly worse OS and TFS compared to those without (median OS 5.7 vs 13.7 y, P<.001; median TFS 1.4 vs 3.9 y, P<.001), Fig. 1. Multivariate analysis identified only del17p (HR 4.35, 95%CI: 2.10-9.01, P<.001) and age at FR (HR 1.04, 95% CI: 1.01-1.07, P=.007) as significant predictors of OS, and del17p (HR 4.3, 95% CI: 2.5-7.5, P<.001) as a significant predictor of TFS. During the follow up period, 351 pts (52%) went on to 2nd-line therapy: ibrutinib 87 (including 2 with BR and 1+R), cyclophosphamide-based (CVP/CHOP) +/- R 102, repeat FR 71, FCR 6, F alone 21, bendamustine +/-R 13, chlorambucil+/-R 38, steroids 3, R alone 3, alemtuzumab 2, other chemotherapy 3 and allotransplant 2. Median follow-up after 2nd-line therapy was 2.8 y (range 0.1-10.8). Median OS and TFS from 2nd-line treatment (TFS2) for ibrutinib (n=87) vs. for other treatments (n=264) was: OS not reached vs 5.3 y, P<.001; TFS2 not reached vs 1.2 y, P<.001. These significant differences persisted when analyses were restricted to those who received ibrutinib vs. chemoimmunotherapy (n=169): median OS not reached vs. 6.3 y (P=.002); median TFS not reached vs. 1.7 y (P<.001), Fig. 2. 2 y OS and TFS2 after ibrutinib were 91% (95% CI: 80-96%) and 78% (95% CI: 65-87%), respectively. A total of 202 malignancies were recorded after initiation of FR in 166 pts (24.7%), Table 1. The median time from FR to 2nd malignancy was 2.3 y (range 0.1-13.5). Richter's transformation (RT) occurred in 36 pts (5.3%) at median 1.9 y (range 0.1-13.2) from FR. Most frequent 2nd malignancies were: non-melanoma skin cancer (11.7%), lung (2.5%), colon (2.1%), other heme (1.9%), and prostate (1.8%). There were 4 cases of acute myeloid leukemia (AML), 2 of which received alkylator therapy after FR prior to AML diagnosis. Conclusions: In this large, homogeneous cohort of CLL/SLL pts treated with first-line FR, including nearly 40% of pts ≥ age 70, we demonstrate a short median TFS of 3.8 y; however, a long OS of 11.6 y. Rates of 2nd malignancies are low after this non-alkylator based chemoimmunotherapy regimen. Ibrutinib for R/R CLL/SLL after FR resulted in significantly improved survival over alternate therapy, with excellent 2 yr OS 91% and TFS 78%. These data demonstrate the efficacy of FR and the benefit of ibrutinib over chemoimmunotherapy as second-line therapy for CLL/SLL in the real-world.

AbstractVenetoclax (VEN) plus azacitidine has become the first-line therapy for elderly patients with acute myeloid leukemia (AML), and has a complete remission (CR) plus CR with incomplete recovery of hemogram rate of ≥70%. However, the 3-year survival rate of these patients is < 40% due to relapse caused by acquired VEN resistance, and this remains the greatest obstacle for the maintenance of long-term remission in VEN-sensitive patients. The underlying mechanism of acquired VEN resistance in AML remains largely unknown. Therefore, in the current study, nine AML patients with acquired VEN resistance were retrospectively analyzed. Our results showed that the known VEN resistance-associated BCL2 mutation was not present in our cohort, indicating that, in contrast to chronic lymphocytic leukemia, this BCL2 mutation is dispensable for acquired VEN resistance in AML. Instead, we found that reconstructed existing mutations, especially dominant mutation conversion (e.g., expanded FLT3-ITD), rather than newly emerged mutations (e.g., TP53 mutation), mainly contributed to VEN resistance in AML. According to our results, the combination of precise mutational monitoring and advanced interventions with targeted therapy or chemotherapy are potential strategies to prevent and even overcome acquired VEN resistance in AML.
