A Phase 2 Trial of Ibrutinib and Nivolumab in Patients with Relapsed or Refractory Classical Hodgkin's Lymphoma

Introduction: Classical Hodgkin's Lymphoma (cHL) is characterized by an extensive inflammatory infiltrate with abundant Th2 and Treg cells which facilitate immune escape of Reed Sternberg (RS) cells and provides a growth promoting microenvironment by cytokine secretion and CD40/CD40L engagement. Our group previously show that ibrutinib irreversibly inhibits both Bruton's tyrosine kinase (BTK) and interleukin-2 inducible kinase (ITK), a kinase important in Th2 signaling (Dubovsky et al Blood 2013). We hypothesized that the addition of ibrutinib to nivolumab would lead to deeper and more durable responses in cHL by normalizing the Th1/Th2 balance thus reversing immune escape of RS cells. We present results of a planned interim analysis of the first 10 patients enrolled with a data cutoff of June of 2020. Methods: This is a single arm, phase II, single institutional clinical trial testing the clinical activity of nivolumab in combination with ibrutinib in patients ≥18 years of age with histologically confirmed cHL who have received at least one prior line of therapy and who were either not candidates for or had a prior autologous stem cell transplant (ASCT). Prior treatment with nivolumab was allowed. Ibrutinib was administered at 560 mg daily until progression in combination with nivolumab 3 mg/kg IV every 3 weeks for 16 cycles. The primary objective was complete response rate (CRR) prior to cycle 7 assessed per Lugano criteria. Adverse events (AEs) were reported using CTCAE Version 4.0. Results: Of the first 11 cHL patients enrolled, one patient withdrew consent prior to initiating therapy. Of the remaining 10 patients, the median age was 41 years (range 20-84) and 4 patients (40%) were male. The median number of prior lines of treatment was 4.5 (range 1-11), 5 patients (50%) had prior ASCT, 8 patients (80%) had prior brentuximab, and 5 patients (50%) had prior nivolumab. Four of the five patients with prior nivolumab had progressed while receiving therapy while the remaining patient had stable disease upon completing nivolumab with a median time from the last nivolumab treatment of 15.6 months (range 0.7-23.2). Of the 10 patients who received treatment, one patient came off study after two cycles due to persistent grade 2 transaminitis lasting for several weeks attributed to nivolumab requiring high dose oral steroids. One patient came off study after cycle 9 due to grade 3 hematuria attributed to ibrutinib and another came off study due to a pericardial effusion after 8 cycles of ibrutinib maintenance. In the remaining patients, treatment was generally well tolerated with most AEs being grade 1-2 (Table 1). The median number of total cycles received was 9 (range 2-22). Of the 9 patients evaluable for response, 6 patients responded (ORR = 66%), 4 of whom had a complete response (CRR = 44%) with a median time to response of 2 months (Table 2, Fig.1). In intention-to-treat analysis, the ORR was 60% and CRR was 40% meeting our prespecified interim efficacy endpoint of a 30% CRR for trial continuation. Notably, of the 5 patients with prior nivolumab, 3 responded to nivolumab + ibrutinib (ORR = 60%), with one having a CR (CRR = 20%). Overall, at a median follow up of 9.5 months, both the median PFS and duration of response have not yet been reached, with 3 patients remaining in CR at the time of data cutoff. Three of 4 patients discontinued trial treatment to undergo SCT [2 allogeneic; 1 autologous]. Of the 2 allogeneic SCT patients, the first one underwent SCT 3 weeks after the last nivolumab infusion and developed multi-organ acute graft-versus-host disease (GVHD) followed by severe chronic GVHD requiring extracorporeal photopheresis. The second patient underwent allogeneic SCT 2 months following the last nivolumab infusion and had no acute GVHD and experienced only mild chronic GVHD which was medically managed. Conclusions: Although the numbers are small and further recruitment is ongoing (target n=17), the combination of ibrutinib and nivolumab was generally well tolerated and with high response rate with more than half of responding patients achieving a CR. In addition, responses were seen in patients with prior nivolumab treatment. Our results suggest a possible novel role for BTK inhibition in reversing nivolumab resistance in cHL, at least in some cases. Correlative studies including peripheral blood and tumor immune subset analyses are ongoing and the latest results will be presented at the meeting.

Abstract PURPOSE: This study aimed to determine activity and safety of the CXCR4 inhibitor plerixafor in combination with bortezomib and dexamethasone in patients with relapsed or refractory Multiple Myeloma (MM). This was based on our preclinical studies showing that plerixafor (Mozobil, Sanofi Corporation) induces de-adhesion of MM cells and sensitization to bortezomib in preclinical animal models. PATIENTS AND METHODS: Theprimary endpoint of the phase I study was the maximum tolerated dose (MTD) and for the phase II study, the safety and response rate of the combination. Eligibility criteria included patients with relapsed or relapsed/refractory MM with 1-5 prior lines of therapy including bortezomib (unless patients were refractory to bortezomib). The phase I included 8 cohorts with different doses and two treatment schedules. In cohorts 1-5, patients received plerixafor at the recommended dose sq on days 1-6 of each cycle and bortezomib at the recommended dose twice a week on days 3, 6, 10, and 13 every 21 days. In cohort 5b-6, plerixafor was given at the recommended dose sq on days 1, 3, 6, 10, and 13 and bortezomib was given at the recommended dose twice a week on days 3, 6, 10, and 13 every 21 days. For the phase II portion patients received plerixafor at the MTD established in phase I of trial, 320 mcg/kg sq on days 1, 2, 3, 6, 10, and 13. Bortezomib was given 1.3 mg/m2 IV or sq twice a week on days 3, 6, 10, 13, every 21 days. Dexamethasone was given at 40mg on days of Bortezomib. RESULTS: A total of 58 patients were enrolled on this study from June 2009 to March 2015, with 25 on the phase I and 33 on the phase II study. In the phase I study, the median age was 60 years (range, 43-85), the median number of prior therapies was 2 (range, 1-4), with all but 3 patients receiving prior bortezomib. The median number of cycles on therapy was 4 (1-12). Dose limiting toxicities including insomnia, restlessness, and psychosis were observed in two patients at dose level 6 (plerixafor 0.40 mg/kg and bortezomib 1.3 mg/m2). Therefore, 3 additional patients were enrolled at dose level 5b (plerixafor 0.32 mg/kg and bortezomib 1.3 mg/m2). There were no grade 4 toxicities. Grade 3 toxicities included lymphopenia (40%), hypophosphatemia (20%), anemia (10%), hyponatremia (10%), hypercalcemia (10%), and bone fracture due to myeloma bone disease (10%). Twenty-three patients were evaluable for response, including 1 (4%) complete response (CR), 1 (4%) very good partial response (VGPR), 1 partial remission (PR) and 2 (9%) MR, and 15 (65%) having stable disease with only 3 (13%) progressive disease (PD). In the phase II study, the median age was 63 (46-83). The median number of prior therapies was 2 (1-5), with 22 (66%) who have received prior bortezomib. The median number of cycles on therapy is 5 (1-24). The response rate included 5 VGPR (16%), 11 PR (35%) with an overall response rate of 51% and another 11 (35%) stable disease. Grade 3/4 toxicities included thrombocytopenia (68%), lymphopenia (6%), hypophosphatemia (2%), anemia (4%), infections (4%), hyponatremia (2%), hypercalcemia (2%) and neurological toxicity (2%). We also examined in vivo mobilization of plasma cells, CD34+ hematopoietic stem cells and other accessory bone marrow cells. Analysis of these samples showed rapid mobilization of plasma cells at 2 hours post-plerixafor with a rapid return to normal levels at 4 and 24 hours post plerixafor. CONCLUSIONS: The combination of plerixafor and bortezomib is generally well tolerated with minimal neuropathy or other toxicities seen to date. The responses observed are strongly encouraging with 51% ORR in this relapsed and refractory population. This study was supported by R01CA133799-01, and by Sanofi and Takeda Corporations.

Abstract Introduction: Despite recent advances, mantle cell lymphoma (MCL) remains difficult to treat with frequent chemoresistance in the relapsed or refractory setting. Ibrutinib, a first-in-class, once-daily, oral covalent inhibitor of Bruton’s tyrosine kinase, demonstrated durable single-agent efficacy in a previous phase 2 study of patients with MCL who had received 1 to 5 prior therapies (Wang M, et al. N Engl J Med. 2013;369:507-516). In that study, the investigator-assessed overall response rate was 68% (complete response rate, 21%). The current study reports on the efficacy and safety of single-agent ibrutinib specifically in patients with MCL who had received a rituximab-containing regimen and had progressed after at least 2 cycles of bortezomib therapy. Methods: In this phase 2, multicenter, single-arm study, patients received 560 mg/day oral ibrutinib continuously until progressive disease or unacceptable toxicity. The primary end point was the overall response rate (ORR) in response evaluable patients, as assessed by an Independent Review Committee (IRC). Secondary end points, also assessed by IRC, included duration of response (DoR), progression-free survival (PFS), overall survival (OS), and safety. Results: 120 patients in this international multicenter study were enrolled. The median age was 67.5 years, ranging from 35 to 85 years with 62.5% ≥ 65 years. Most patients had stage IV disease at study entry (77.5%), and 9.2% were reported as blastoid variant (per investigator). 76.3% of patients had an intermediate or high risk simplified MIPI score, and 52.5% had bulky disease (longest diameter ≥ 5 cm). Forty two (35.0%), 67 (55.8%) and 11 patients (9.2%) had an ECOG score of 0, 1 and 2, respectively. The median number of prior lines of systemic therapy was 2 (range 1-8 lines) with almost half of the patients (47.5%) receiving 3 or more prior lines of therapy. Overall, 33% of patients had received prior stem cell transplantation. At the time of clinical cut-off for the primary analysis (29 April, 2014), median follow-up was 14.9 months with median treatment duration of 8 months (range: 0.5-20.9 months). The main reasons for treatment discontinuation were disease progression in 53 patients (44.2%) and an adverse event (AE) in 8 patients (6.7%). The ORR for response evaluable patients was 62.7% (95% confidence interval [CI]: 53.7%-71.8%) with a complete response rate of 20.9%. Subgroup analysis suggested that the ORR was independent of age, gender, geographic region, number of prior lines of therapies, baseline extranodal disease, simplified MIPI score, bulky disease, and stage of MCL. Median DoR by IRC was 14.9 months and the median time to first response was 2.1 months, ranging from 1.3 to 6.3 months. Median PFS was 10.5 months and 47% of the patients remained progression-free at 1 year. The OS rate at 18 months was 61%. The most common AEs were fatigue (any grade, 43.3%; grade 3 or 4, 3.3%) and diarrhea (any grade, 42.5%; grade 3 or 4, 2.5%). The most common grade 3 or higher AEs were neutropenia (20.8%), thrombocytopenia (13.3%), and pneumonia (12.5%). Any-grade hemorrhagic events were reported in 45 patients (37.5%), including 3 (2.5%) with major hemorrhagic events. The median time to initial hemorrhagic event was 84 days (range 1-515 days), with a median duration of 22 days (95% CI: 8-31 days). Atrial fibrillation was reported in 13 patients (10.8%), which was grade 3 or 4 in 6 patients (5%). AEs led to dose reductions in 8 patients (6.7%). Conclusion: Single agent ibrutinib is highly efficacious and well tolerated, with an acceptable toxicity profile in patients with MCL who progressed after rituximab-containing chemotherapy and bortezomib therapy. These results are consistent with previous ibrutinib studies, with no new safety signals.

Abstract Background: Hypomethylating agents (HMA) are the standard of care for higher risk MDS patients (pts). Fewer than one-half will respond to therapy for an average duration of one year, thereby emphasizing the necessity to optimize the use of these disease modifying agents. HMA clinical trials have not addressed the optimal time in the disease course to initiate treatment to maximize disease-modifying potential. The current dogma is to begin HMA therapy in all higher risk MDS pts at the time of initial diagnosis. Nevertheless, a subset of higher risk MDS pts will have adequate hematopoiesis at the time of diagnosis regardless of disease risk, and for these pts therapy may be delayed and reserved for a later time when symptomatic cytopenias develop. We investigated the impact of the timing of HMA initiation on outcomes among higher risk MDS pts presenting with adequate blood counts to discern the possible benefit of early treatment based solely on disease risk. Methods: We identified MDS pts with intermediate-2 and high risk IPSS (higher risk) MDS treated with HMA among the Moffitt Cancer Center database. We included patients with adequate hematopoiesis defined for the purpose of this study as platelets >50 x 109/L, Hgb > 9 g/dl and ANC > 0.5 x 109/L and being transfusion independent to exclude those pts in need of HMA treatment for cytopenias. We divided patients into 4 groups based on the time of HMA initiation (within 30, 31-60 , 61-90 and greater than 90 days from time of diagnosis). We compared baseline characteristics, best response rate to treatment using international working group criteria (IWG 2006), leukemia free survival (LFS) and overall survival (OS) among the 4 groups. Results: We identified 320 higher risk MDS pts with adequate hematopoiesis who were treated with HMA. Baseline characteristics for the 4 groups based upon time of HMA therapy initiation are summarized in Table-1. Pts receiving treatment within 30 days had higher marrow myeloblast percentage at time of diagnosis. There was no difference in mean blood counts at time of diagnosis between the 4 groups; however, mean platelet count was lower at time of initiating HMA therapy in patients treated after 90 days from diagnosis. Table-2 summarizes somatic gene mutation data among 110 patients tested. TET-2 mutations were more common among those treated within 60 days, whereas U2AF1 mutations were more common among those treated after 60 days from diagnosis. The complete response rates were 21%, 26%, 23% and 7%, respectively for pts treated within 30 , 31-60 , 61-90 and greater than 90 days from time of diagnosis (p=0.046). The overall response rates (defined as hematological improvement or better) were 43%, 41%, 43% and 34%, respectively for pts treated within 30, 31-60 , 61-90 and greater than 90 days from date of diagnosis (p .70). There was no difference in mean duration of treatment with HMA among the groups with mean durations of 267, 204, 224 and 215 days, respectively, (p .35). The median OS from the date of diagnosis was 641, 550, 979 and 806 days, respectively for pts treated within 30, 31-60, 61-90 and greater than 90 days from date of diagnosis (p .2). There was no impact of timing for HMA initiation when adjusted for Revised-IPSS risk groups in Cox regression analysis. There was no difference in OS based on HMA initiation time when adjusted for myeloblasts % or karyotype. Further, there was no difference between groups in rate of AML transformation or LFS (p =.7 and .16, respectively). Conclusions A delay in initiating HMA therapy in higher risk MDS pts with adequate blood counts is not associated with worsened overall survival or increased frequency of leukemia transformation. Complete response rates were higher when treatment was started earlier in the disease course, however, there was no difference in overall response rate. Close observation to initiate treatment upon development of clinically significant cytopenias appears to be a safe and equally effective strategy among pts with higher risk MDS.

Abstract Standard treatment for patients with chronic lymphocytic leukemia (CLL) is rapidly evolving and gradually has incorporated the combined use of monoclonal antibodies (mAbs) and targeted therapy with small molecules. Single agent Ibrutinib (Ibr), a first-in-class BTK inhibitor, is effective in previously untreated patients including those that are older than 65 or considered unfit to receive chemotherapy-based combinations. The complete response rate in patients receiving single agent Ibr is relatively low (overall response rate of 86% and complete response of 4% based on 2008 iwCLL criteria), though most patients have durable remissions. The combination of Ibr with mAbs like Obinutuzumab-Gazyva (G), a third-generation anti-CD20 mAb, can ameliorate the Ibr-induced lymphocytosis and increase the overall and complete response rates. Accordingly, we initiated an open-label phase Ib/II clinical study of Ibr in combination with G for first-line therapy of previous untreated pts with CLL. The study completed enrollment of 32 previously untreated patients with CLL. Patients received G administered based on FDA dosing recommendations for 6 cycles (28 days/cycle) and Ibr 420mg po (1-3 hours before starting G infusion), and daily for up to 3 years. All patients received prophylactic medications. Patients were assessed for response by 2008 iwCLL criteria two months after completion of G, as the primary efficacy endpoint. The median age of the patients was 65 (range: 46-78) years. 84% of the patients had a CIRS >6, 45% had a Rai stage III-IV and 19% had an ECOG performance ≤2. The median baseline absolute lymphocyte count (ALC) was 79x103/mm3(range: 1.4-412.4). Patients showed the following FISH/cytogenetic abnormalities: del(13q) in 55%, trisomy 12 in 23% and del(11q) in 19%. Only 2 (6%) of these patients showed del(17p). From the patients with IGVH mutational status available (n=17), 11 (65%) were unmutated (>98% homology). Most adverse events (AEs) were grade 1-2 (74%). Six patients (19%) had grade 1-2 G-infusion-related reaction (IRR) and only one patient (3%) showed grade 3 IRR (without the need for G discontinuation). We observed neutropenia (all grades: 52%, grade 3-4: 23%), thrombocytopenia (all grades: 71%, grade 3-4: 19%) and anemia (all grades: 26%). There were no cases of febrile neutropenia. Two patients (6%) had grade 1 bleeding (one patient with asymptomatic lower gastrointestinal bleeding and the second patient with epistaxis) that resolved spontaneously without requirement of blood transfusion or study treatment discontinuation. Two patients (6%) developed pneumonia, one was community-acquired pneumonia requiring inpatient treatment with IV antibiotics; the study treatment was held until resolution of symptoms and re-initiated at full dose. The most frequent non-hematological AEs were diarrhea, transaminitis, hyperbilirubinemia, hyperglycemia, and electrolyte alterations (grade 1-2). Three patients (9%) discontinued Ibr due to atrial fibrillation grade 1 (n=1), rash and headaches grade 2 (n=1), and persistent grade 4 thrombocytopenia (n=1). Twenty-three patients were evaluable for response assessment by 2008 iwCLL criteria (median follow-up of 11 months). 84% of the patients showed a rapid decrease in ALC from baseline during the first cycle of treatment and only four patients (13%) required more than 3 cycles of treatment to achieve an ALC response. The overall response rate was 100%. The majority of pts had a partial response and six of 23 evaluable patients (26%) achieved a complete remission with detectable Minimal Residual Disease in the bone marrow by multiparametric flow cytometry. In summary, Ibr-G combination has been generally well tolerated. AEs have been consistent with the known safety profiles of Ibr and G individually. The patients that discontinued Ibr remain in follow-up without disease progression. 100% of evaluable patients achieved response after 6 months of combination therapy, and 26% of patients met CR criteria. One important finding thus far has been a very low rate of IRR, (19% grade 1-2 and 3% grade 3-4), suggesting that Ibr can strongly mitigate the incidence and severity of G associated IRR.

Abstract Background : The role of reduced-intensity conditioning allogeneic hematopoietic cell transplantation (RIC-HCT) in adult acute lymphoblastic leukemia (ALL) remains unclear because the interpretation of transplantation outcome is mainly limited by the small sample size, short follow-up duration, various regimens for conditioning and graft-versus-host disease (GVHD) prophylaxis, and the heterogeneity of the criteria used to select patients for RIC-HCT. Previously, we conducted a phase 2 trial of RIC-HCT in adults with high-risk ALL who were ineligible for myeloablative conditioning and showed the potential role of this strategy, especially in patients in first complete remission (CR1). Here, we report the long-term outcomes of RIC-HCT by analyzing 122 consecutive adults with high-risk ALL in CR1, particularly focusing on the prognostic relevance of chronic GVHD. Methods: During the period between 2000 and 2014, 122 patients in CR1 (median age, 52 years [range, 15-65 years]; 54 Ph-negative ALL and 68 Ph-positive ALL) were given an identical RIC regimen consisting of fludarabine (150 mg/m2 in total) and melphalan (140 mg/m2in total). The indications for RIC-HCT were advanced age (≥50 years; n=79; 64.8%) and comorbid conditions (n=43; 35.2%). Graft sources were peripheral blood stem cells (n=118; 66 matched sibling donor, 23 matched unrelated donor, 29 mismatched unrelated donor) and bone marrow (n=4; 1 matched sibling donor, 1 matched unrelated donor, 2 mismatched unrelated donor). The median time to transplantation was 155.5 days (range, 103-291 days). GVHD prophylaxis was attempted by administering calcineurin inhibitors (cyclosporine for sibling donor transplants, tacrolimus for unrelated donor transplants) plus methotrexate. Antithymocyte globulin was administered to the patients who received mismatched unrelated donor grafts. If residual leukemia was detected in the absence of GVHD at 3 months after transplantation, calcineurin inhibitors were rapidly discontinued. Results: The median time for neutrophil and platelet recovery was 12 days (range, 8-30 days) and 13 days (range, 5-60 days) after RIC-HCT. Sixty-two patients developed acute GVHD (53 grade II, 5 grade III, 4 grade IV). The cumulative incidence of acute GVHD at 1 year was 50.8% (42.6% for Ph-negative and 57.4% for Ph-positive, P=0.152). Except for 11 patients with early deaths within 100 days, 77 developed chronic GVHD (30 mild, 29 moderate, 18 severe), resulting in a 5-year cumulative incidence of 63.6% (69.1% for Ph-negative ALL and 58.8% for Ph-positive ALL, P=0.319). The median time to onset of chronic GVHD was 140 days (range, 37-843 days) after transplantation. Cytomegalovirus reactivation >10,000 copies/mL was observed in 40.2% (44.4% for Ph-negative ALL and 36.8% for Ph-positive ALL, P=0.447). After a median follow-up duration of 57.9 months (range, 17.7-206.8 months), the 5-year cumulative incidence of relapse (CIR) and non-relapse mortality (NRM) were 27.5% (23.9% for Ph-negative ALL and 30.2% for Ph-positive ALL) and 19.0% (17.4% for Ph-negative ALL and 20.3% for Ph-positive ALL), respectively, and the 5-year disease-free survival (DFS) and overall survival (OS) rates were 53.5% (58.4% for Ph-negative ALL and 49.7% for Ph-positive ALL) and 59.8% (60.2% for Ph-negative ALL and 59.3% for Ph-positive ALL). In multivariate analysis, the presence of chronic GVHD lowered CIR (HR, 0.23; 95% CI, 0.10-0.48; P<0.001), but severe chronic GVHD increased NRM (HR, 8.76; 95% CI, 3.39-22.6; P<0.001). Thus, the presence of mild to moderate chronic GVHD was closely related to better outcomes in terms of DFS (HR, 0.45; 95% CI, 0.32-0.64; P<0.001) and OS (HR, 0.44; 95% CI, 0.30-0.64; P<0.001) in all patients as well as in both subgroups of patients. In Ph-positive ALL subgroup of patients, patients without achievement of major molecular response until the time of transplantation had also significantly higher CIR (HR, 7.42; 95% CI, 3.04-18.10; P<0.001) and poorer DFS (HR, 3.47; 95% CI, 1.48-8.14; P=0.004) and OS (HR, 2.58; 95% CI, 1.03-6.47; P=0.043). Conclusion: Our long-term follow-up data with a uniform treatment strategy suggest that RIC-HCT is a valid alternative choice for providing a long-term disease control for adult high-risk ALL patients in CR1. Minimal residual disease-based treatment strategies to reduce leukemia cell burden before HCT and to enhance the graft-versus-leukemia effect are needed in the future.

Abstract Chronic extensive, severe graft-versus-host-disease (GVHD) is a major cause of morbidity and mortality following an allogeneic hematopoietic stem cell transplant (HSCT). Patients with progressive chronic GVHD (cGVHD) following standard treatments have limited options. Patients with extensive refractory cGVHD have a decreased performance status (PS) and an increased non-relapsed mortality. Extensive sclerodermatous cGVHD responds poorly to standard treatments. Colchicine is a well-known anti-inflammatory drug that has been used in the treatment of many inflammatory disorders (1). We report a series of 8 patients with extensive cGVHD who were refractory to multiple lines of therapy and then were treated with colchicine. All patients had improvements in ECOG PS, skin GVHD and/or oral GVHD after starting colchicine. All patients were able to decrease their immunosuppressive therapies (IST) after starting colchicine. We retrospectively examined 8 patients with refractory extensive cGVHD, treated with colchicine (0.6 mg QD or BID). IST for cGVHD was defined by the following: steroids, extracorporeal photopheresis (ECP), imatinib, mycophenolate mofetil (MMF), tacrolimus, bortezomib, montelukast, cyclophosphamide (Cy), pentostatin, and rituximab. National Institutes of Health 2014 cGVHD consensus criteria (2) were used to grade the cGVHD prior to colchicine and at the time of best response after colchicine was started. Baseline patient characteristics are listed in Table 1. Conditioning regimen for allogeneic HSCT consisted of PPT (ECP, pentostatin, TBI) (4/8), busulfan/Cy (2/8), Cy-TLI (1/8), or Cy/TBI (1/8). GVHD prophylaxis involved CSA/MTX (7/8), tacrolimus/MTX (1/8) and ATG in addition to CSA/MTX (1/8). Median number of organs involved in cGVHD was 4.5 (range 2-5). All patients had extensive cGVHD with skin (8/8), oral (8/8), eye (8/8), GI (7/8), lung (6/8), liver (2/8), and/or genital (2/8) involvement. Median number of failed IST was 3.5 (range 1-6). Patients failed steroids (7/8), ECP (6/8), MMF (5/8), imatinib (3/8), cyclophosphamide (2/8) and bortezomib (1/8). Median number of IST immediately before colchicine was 2.5 (range 1-6). Most patients required twice daily dosing of colchicine (5/8). Median follow-up since beginning colchicine was 11 weeks (range 3-67 weeks). At best response with colchicine, all patients had clinical improvement of chronic GVHD (Figure 1). Patients with extensive cGVHD of the skin, including all patients with extensive sclerodermatous changes, responded to the addition of colchicine, and had steroid and MMF doses lowered, and/or were stopped on IST. Median number of IST fell to 2 (range 0-5). Four patients had a reduction in the number of IST. One patient was taken off 4 IST (ECP, imatinib, Cy and MMF). Another patient was able to stop ECP. Five patients had a reduction in prednisone with median reduction of 5mg (range 5-40 mg), while 2 had reductions in the total daily dose of MMF. Adverse events were uncommon and included 2 patients with grade 1-2 diarrhea. The most severe adverse event was grade 2 diarrhea in one patient that led to eventual discontinuation of colchicine. No hematologic toxicity was observed. The rest (7/8) continued on colchicine therapy. In conclusion, patients with extensive cGVHD involving the skin and mouth, refractory to multiple lines of IST, experienced clinical improvement on colchicine. Toxicity was limited to mild GI side effects. These observations need to be validated in a prospective clinical trial. References (1) Slobodnick et al. Am J Med. 2015 May;128(5):461-70.

Abstract Introduction: The BEAM (carmustine (BCNU), etoposide, aracytin and melphalan) standard conditioning regimen in autologous stem-cell transplantation is widely used since 1990 in patients with relapsed/refractory non Hodgkin's lymphoma (NHL) and Hodgkin's lymphoma (HL) who remain sensitive to salvage therapy. Recently, a phase Ib-II feasibility study using bendamustine rather than BCNU in the same indication was reported, but was not really compared to BEAM concerning safety. We report herein a safety analysis of Bendamustine-EAM (BeEAM) with a control BEAM counterpart paired cohort (2/1). Methods: We performed a case control retrospective study of patients with NHL and HL who underwent high-dose chemotherapy (HDC) with BeEAM regimen between January 2015 and December 2015. We matched each BeEAM patient with two patients having the same age, sex and number of treatment lines who underwent BEAM and ASCT between January 2008 and December 2014. No patient presented significant comorbidity. The BEAM regimen consisted in BCNU on day -6 (300mg/m2) cytarabine daily from day -6 to day -3 (200mg/m2 every 12 hours), etoposide daily from day -6 to day -3 (100mg/m2 every 12 hours) and melphalan on day -2 (140mg/m2). A similar scheme was adopted in BeEAM arm with bendamustine on day -6 and -5 (100mg/m2/d) replacing BCNU. Autologous stem cells were reinfused on day 0. Unfractionated heparin was used with Bendamustine to prevent veno-occlusive disease. Pegfilgrastim 6mg was injected subcutaneously on day 4. Febrile neutropenia was treated according to ESMO guidelines. Results: One hundred and two patients (68 BEAM and 34 BeEAM) were analyzed. Median age was 48 years in both arms. 61.8% of patients were male and 38.2% female. A median number of 4.4 x106 CD34 were reinfused in the two groups. The median time to neutrophils recovery (> 0.5 x109) was similar between the two arms (9.06 vs 8.86 days, p=0.3). Grade 3 or greater diarrhea according to Commun Terminology Criteria for Adverse Events (CTCAE v4.03) classification was significantly more frequent in BeEAM patients (44 vs 13.2%, p=0.001). Median time to hospital discharge was significantly longer in BeEAM group (23 vs 20.8 days, p=0.0047). The median loss of weight during hospitalization was significantly greater in BeEAM patients (3.3 vs 1.9 kg, p=0.014). The median number of days with fever >38°C and with intravenous antibiotics was significantly higher in BeEAM group (6.06 vs 3.38, p<0.001; 10.76 vs 8.22, p=0.0012 respectively). Five patients in BeEAM arm (14.7%) and 3 patients in BEAM (4.4%) developed grade 2-3 liver cytolysis. Four patients in BeEAM arm developed grade 1 renal toxicity. Six patients presented bacteremia (17.6%) in BeEAM versus 8 patients (11.7%) in BEAM arm. Incidence of mucositis, nausea and vomiting was similar between the two groups. Four patients in the BeEAM arm were rehospitalized for recurrent fever three to five days after discharge. No death occurred in both groups during the ASCT procedure. Conclusion: Our results based on retrospective case-control study suggest that BeEAM conditioning regimen followed by ASCT seems to be more toxic than the standard BEAM regimen.

BACKGROUND: In multiple myeloma (MM), deep responses have been associated with improvements in progression-free survival (PFS) and overall survival (OS). Response kinetic data, including renal response times, which are highly important for patients with renal impairment, are infrequently reported. We analyzed the association between depth of response, including minimum residual disease (MRD) negativity, plus response kinetics and long-term outcomes, using data from the randomized, open-label, phase 3 ICARIA-MM study. ICARIA-MM evaluated the anti-CD38 monoclonal antibody isatuximab (Isa) in combination with pomalidomide and dexamethasone (Pd) versus Pd in patients with relapsed/refractory MM (RRMM) after ≥2 prior lines of therapy (NCT02990338). METHODS: All patients received standard doses of Pd and those randomized to the Isa-Pd group received 10 mg/kg IV on days 1, 8, 15, and 22 (cycle 1), and days 1 and 15 in subsequent 28-day cycles. Depth and kinetics of response were analyzed for each treatment group. MRD was assessed at 10-5 (tested by next-generation sequencing in patients with complete response [CR] / stringent CR [sCR]). Time to tumor response, time to renal response (CRenal; improvement in estimated glomerular filtration rate (eGFR), using the MDRD formula, from <50 mL/min/1.73m² at baseline to ≥60 mL/min/1.73m² at ≥1 post-baseline assessment), and time to sustained CRenal (a CRenal lasting ≥60 days) were recorded. No neutralization assay was used for patients with IgG kappa clonality. RESULTS: Overall, 307 patients were randomized to Isa-Pd (n=154) or Pd (n=153), of whom 33/142 (23.2%) and 24/145 (16.6%) patients had eGFR <50 mL/min/1.73m² at baseline. Patients had received a median of 3 prior lines of therapy (range 2-11) and 73.4% and 71.9% of patients in the Isa-Pd and Pd groups, respectively, were double refractory. Median PFS was 11.53 months with Isa-Pd and 6.47 months with Pd (hazard ratio [HR] 0.596; 95% confidence interval [CI] 0.436-0.814). Tumor responses on Isa-Pd were more frequent and deeper than on Pd. Overall response rates (ORR) were 60.4% vs 35.3% (odds ratio [OR] 2.80; 95% CI 1.72-4.56; p<0.0001); at least very good partial response rates (≥VGPR) were 31.8% vs 8.5% (OR 5.03; 95% CI 2.51-10.59; p<0.0001). As no isatuximab interference assay was performed, near-complete response rates (immunofixation remained positive) were reported: 15.6% vs 3.3% (OR 5.47; 95% CI 1.96-18.78; p=0.0002). MRD negativity rates in the ITT population were 5.2% vs 0%. Depth of response correlated with improved long-term outcomes in both arms (Figure). After a median follow-up of 11.6 months in the Isa-Pd arm, 100% of MRD-negative (MRD−) patients were progression free and alive. In the Isa-Pd arm, median PFS was longer with increased depth of response: MRD− patients, not reached (NR); ≥VGPR and MRD+, 15.21 months; partial response (PR), 11.53 months; less than PR, 3.29 months. This pattern was also observed for 1-year OS probabilities (100% > 92.9% > 82.4% > 46.4%, respectively). Tumor responses occurred faster with Isa-Pd than with Pd. Among patients who achieved a response of ≥PR (93 in the Isa-Pd arm and 54 in the Pd arm), the median time to first response was shorter for Isa-Pd (1.1 months) than for Pd (1.9 months). Among patients who achieved a response of ≥VGPR (49 and 13 in the Isa-Pd and Pd arms, respectively), the time to first VGPR or better response was similar at 2.9 months for Isa-Pd and 3.0 months for Pd. Renal responses occurred faster in patients on Isa-Pd than on Pd. A CRenal was observed in 23/32 (71.9%) patients in the Isa-Pd arm (median time to response 3.4 weeks) and in 8/21 (38.1%) of patients in the Pd arm (median time to response 7.3 weeks). A sustained CRenal was observed in 10/32 (31.3%) patients in the Isa-Pd arm (median time to first response 2.4 weeks) and in 4/21 (19.0%) patients in the Pd arm (median time to first response 4.8 weeks). CONCLUSION: In the heavily pretreated ICARIA population, Isa-Pd induced more frequent and faster tumor and renal responses than Pd. Depth of response, including MRD negativity, was improved with Isa-Pd and was clearly associated with better long-term survival outcomes. Figure.

Abstract Introduction: Patients (pts) with newly diagnosed multiple myeloma (MM) are commonly treated with the standard of care combination of lenalidomide (Len), bortezomib (Bz), and dexamethasone (Dex), also known as RVD. A recent randomized phase 3 study found that the addition of Bz to Len and Dex significantly increased median overall and progression free survival as well as response rate (Durie et al. Lancet 2017). Mild to moderate peripheral neuropathy (PN) is commonly reported with Bz use, although lower rates of PN have been reported with subcutaneous (SC) administration of single agent Bz compared with IV Bz (Moreau et al. Lancet Oncol 2011). Here we present preliminary results of a multi-center, open-label, single arm phase II trial of Len, SC Bz, and Dex in pts with newly diagnosed MM. Maintenance was risk-stratified, with high risk patients (defined as those with high risk cytogenetics (del17p, t(4:14), t(14;16)) or ISS stage II or III) receiving Bz in addition to Len. Primary endpoints included 1) overall response rate (ORR) after 4 induction cycles, 2) best response to induction therapy, and 3) rate and severity of PN during induction therapy. Methods: Patients enrolled in this study were newly diagnosed with active MM as defined by the revised IMWG criteria (Rajkumar et al. Lancet Oncol 2014). Protocol specified induction treatment consisted of 21-day cycles with Len 25 mg on days 1-14, SQ Bz 1.3 mg/m2 days 1, 4, 8, and 11, and Dex 20 mg on days 1, 2, 4, 5, 8, 9, 11, and 12. Stem cell mobilization followed induction cycle 4 and patients subsequently proceeded to either high dose melphalan and autologous stem cell transplant (ASCT) or 4 additional cycles of induction therapy based on patient preference with provider input. Following ASCT or completion of the 8th induction cycle pts proceeded to risk-stratified maintenance therapy. Maintenance consisted of 28-day cycles of therapy with Len on days 1-21 for all patients, while those pts defined as high-risk also received SC bortezomib Bz on days 1 and 15. Patients remained on maintenance therapy until progression, unacceptable toxicity, or withdrawal from protocol-directed treatment. Response was based on the IMWG uniform criteria (Rajkumar et al. Lancet Oncol 2011) and toxicities were graded based on the NCI-CTCAE V4. Correlative samples of blood and bone marrow for genomics and proteomics were collected from baseline and then throughout the study, and are currently being analyzed. Results: Forty-five pts were enrolled across 8 US sites between December 2015 and June 2017. Median age at enrollment was 61 years (range: 43 to 79) and 60% of the patients were male, 40% female. FISH cytogenetics found del 17p in 8% of pts tested, t(14;16) in 9%, and t(4;14) in 14%. At baseline, 60% of pts were ISS II/III. High risk pts comprised 62% of the study population overall. 80% of pts (36/45) collected stem cells and 31% of pts (14/45) continued to ASCT. The median number of CD34+ stem cells collected was 9.67 x 10^6. The median number of induction cycles completed was 8 (1 to 8 cycles) and 43 of 45 pts were evaluable for the primary endpoint of response after 4 induction cycles, with preliminary results indicating an ORR of 91% (39/43). Three pts did not reach the end of cycle 4 and 1 patient had stable disease. ORR at any point up to the beginning of maintenance was 98% (42/43). Any grade PN was reported by 80% of patients, including 38% with grade 1 and 36% with grade 2 PN. There were two cases of Grade 3 PN and one case of Grade 4 PN. Among the three patients with Grade ≥ 3 PN, symptoms improved to Grade ≤ 2 with dose reduction, modification of treatment schedule, or discontinuation of Bz. Importantly, given the higher than expected rate of all and high-grade PN, hydration with IV normal saline 500-1000 ccs prior to Bz administration as part of supportive care in selected patients was instituted and a comprehensive evaluation of the impact of this intervention on PN is in process. Conclusions: The combination of RVD with SC Bz is a highly effective treatment regimen for patients with newly diagnosed MM, including high risk pts. However, rates of all- and high-grade PN were greater than expected despite the use of SC Bz. Prompt dose reduction and/or change in schedule of Bz administration to weekly administration is recommended, with careful attention to supportive care in order to further improve tolerability.

Abstract Abstract 2964 Background. Lenalidomide is an oral IMiD®, immunomodulatory compound, approved for use in combination with dexamethasone (Len/Dex) in patients with RRMM who have received one prior therapy. Len/Dex is indicated until evidence of disease progression at the best-tolerated dose of both Len and Dex (Dimopoulos et al. Leukemia 2011). However, the tolerability profile of long term exposure to Len/Dex is not well described, and evidence that long term exposure to Len/Dex would improve on the response rate and survival has yet to be determined. We sought to determine the efficacy and safety profile of long term exposure to Len/Dex in RRMM pts in a multicentre study. Method. We retrospectively reviewed the medical records of 50 RRMM pts treated with Len/Dex and remaining on Len for ≥2 years with a special focus on pts receiving Len for ≥3 years. All pts included had complete follow up records. Results. The median (range min-max) age was 58 years (39–79) with 30% (n=15) > 65 years (elderly MM), the sex ratio M/F was 1.2, 49% (n=24) ISS 2 and 3, 12% (n=6) severe renal insufficiency (CrCl < 30mL/min), and 8% (n=4) adverse FISH [del17p and/or t(4;14)]. Overall, 25 pts (50%) had Len/Dex at first relapse, 19 pts (38%) at second relapse and 6 (9%) pts in subsequent relapses. Len/Dex was given at first relapse in 10 (66%) elderly patients. The median time from diagnosis to starting Len/Dex was 4.5 years (1–16) for overall cohort and 3 years (1–8) for elderly patients (p=0.05). 28 pts (56%) received Len/Dex for ≥3 years. The median duration on Len/Dex was 3 (2–7) years for the overall cohort, and was 4 (3;7) years for patients exposed to Len ≥3 years. Treatment duration was similar across age categories and across number of previous relapses. With a median follow up of 4 years, 19 patients had stopped Len/Dex. The response rate (ORR, ≥PR) was 96% (n=48), including 37 (74%) patients with ≥VGPR, similar across age categories. Interestingly, the ORR and ≥VGPR were similar irrespective of whether patients have stopped Len/Dex in our study. The ORR was also similar across number of previous relapses, but the ≥VGPR rate was lower in patients at third relapse and beyond, (50%; p=ns). The ORR and ≥VGPR rate was 93% and 77% in patients exposed to Len ≥3 years, similar to the whole cohort. The median time to first response and best response were 2 (1–5) months and 4.5 (2–9) months, respectively. Overall, 9 (18%) patients stopped treatment due to toxicity, 9 (18%) progression of MM, and 1 (0.5%) patient decision. With a median follow up of 4 years, the median (95%CI) TTP was not reached, the estimated 4-yr TTP was 51.5%. There was no imbalance in the incidence of toxicity based on age, number of previous relapses, and patients exposed to Len ≥3 years did not discontinue more often due to toxicity, 14% versus 19% for those receiving Len < 3 years. The hematological safety profile was similar across age categories, number of previous relapses, and patients exposed to Len ≥ 3 years; overall, 8 (16%) patients experienced grade 3–4 neutropenia, 6% thrombopenia, and 6% anemia. Ten (20%) patients experienced a thromboembolic event (VTE), all of them of venous type. Two patients had previous history of VTE, but none of them experienced VTE on Len/Dex, likely related to adequate VTE prophylaxis. The median time to first occurrence was 5 (1;28) months, although 4/10 occurred in patients with ≥3 years on Len. All VTE occurred while on VTE prophylaxis except for 1 patient, 5 on aspirin, 2 on prophylactic doses of LMWH, and 2 on VKA (target INR 2–3). The incidence rate of second primary malignancy (SPM) was 3 (6%) (larynx, lung, and MDS). The SPMs occurred at a median time of 4 years from start of Len, while Len was already stopped in 2/3 patients, the latter stopped len at time SPM was diagnosed. Interestingly, none of the patients with more than 3 years exposure on Len had SPM. Conclusions. The current study provides estimates of responses, TTP and safety in a series of MM pts with long-term exposure to Len-based regimen at relapse. 62% of patients remained on Len beyond 3 years reflecting the efficacy and good safety profile of Len in relapsed MM, irrespective of age and number of prior therapies. Furthermore, no excess of long term side effects, including SPM, was observed with a prolonged long follow-up in this study. Disclosures: Robinson: Celgene: Employment. Miljkovic:Celgene: Employment.
