Abstract Background: mTOR inhibition has produced responses in mantle cell lymphoma as well as other non-Hodgkin lymphomas. This phase II study tested the oral mTOR inhibitor everolimus (RAD001, Novartis Pharmaceuticals) in simultaneous two-stage phase II lymphoma studies, including one arm involving Hodgkin lymphoma. The goals were to learn the toxicity profile and to assess the anti-tumor response. A total of 17 patients with Hodgkin lymphoma were enrolled in the uncommon arm at completion of enrollment. Methods: Patients (pts) received 10 mg PO daily for each 28 day cycle (up to 12, with a possible extension in responders) and restaged after 2, 6, and 12 cycles. The primary endpoint is the confirmed response rate, including CR, CRu or PR. Results: The median age of the 17 pts with Hodgkin lymphoma was 37 yrs (range: 27–68), with a median of 6 (range, 4–14) prior therapies. Fourteen pts (82.4%) had a prior stem cell transplant (SCT). Pts completed a median of 6 (range, 1–13) cycles of therapy. Fifteen of 17 patients were evaluable for response as of this analysis. The overall response rate was 47% (7/15), all partial responses. Ten patients are continuing on study while 6 have gone off due to disease progression and 1 due to other reasons. Common grade 3 adverse events (AEs) include thrombocytopenia (5 pts), anemia (5 pts) and alkaline phosphatase elevation (1 pts). 1 patient was reported to have grade 4 neutropenia. Conclusions: Oral everolimus has promising activity with acceptable toxicity in Hodgkin lymphoma. These results provide the rationale for additional studies with this novel class of agents and to integrate mTOR inhibitors into salvage treatment regimens for Hodgkin lymphoma.

8055 Background: mTOR inhibition with intravenous temsirolimus (Wyeth Pharmaceuticals) has been associated with responses in mantle cell lymphoma (J Clin Oncol 23;5347, 2005) as well as other lymphomas (Blood 108 (11) 2483; 2006). This phase II study tested the oral mTOR inhibitor everolimus (RAD001, Novartis Pharmaceuticals) in three simultaneous two-stage phase II lymphoma studies - aggressive (group 1), indolent (group 2), or uncommon (group 3). The goals were to learn the toxicity profile and to assess the anti-tumor response. Planned interim analysis for groups 1 and 3 have been completed and are the subject of this report. Methods: Patients (pts) received 10 mg PO daily for each 28 day cycle (up to 12) and restaged after 2, 6, and 12 cycles. The primary endpoint is the confirmed response rate, including CR, CRu or PR. 12 pts were enrolled in stage 1 of each study. At least 1 success in 12 is required to proceed to stage 2, to a total of 37 pts. Overall, the treatment will be considered promising if 4 or more successes are observed in all 37 pts in each group. Results: The median age of the 12 pts in group 1 was 68.5 yrs (range: 53–80), with a median of 3 (range, 1–15) prior therapies. Four pts had a prior stem cell transplant (SCT). Pts completed a median of 7 (range, 1–12) cycles of therapy. 6 confirmed responses have been achieved (1 CR, 5 PR), meeting the overall criteria for promising results in this study. Common grade 3 adverse events (AEs) include thrombocytopenia (3 pts) and anemia (2 pts). For group 3, the median age was 49 yrs (range, 27–78), with a median of 7 (range, 1–13) prior therapies and 6 pts had a prior SCT. Pts have completed a median of 6.5 cycles (range, 1–11). 5 confirmed responses have been achieved (5 PR), meeting the criteria for this regimen to be considered promising. Of these 5 patients, 3 had HD, 1 T-cell NHL, and 1 had macroglobulinemia. Common grade 3 AEs include anemia (3 pts) and thrombocytopenia (2 pts). No grade 4 AEs were reported. Conclusions: Oral everolimus has activity in a spectrum of lymphomas with acceptable toxicity. The responses observed in both group 1 and group 3 met the criteria to continue accrual. These results provide the rationale for additional studies with this novel class of agents and to integrate mTOR inhibitors into salvage treatment regimens.

8569 Introduction: Relapsed or refractory MCL patients demonstrated a promising overall response rate (ORR) of 53% with a median duration of response (DR) of 13.7 months to single-agent lenalidomide when analyzed as a subset in a recent a phase II study (NHL-002). A supporting international phase II trial (NHL-003) of single-agent lenalidomide was initiated for patients with relapsed or refractory aggressive NHL. In this report, we analyze the current results from the MCL patients enrolled in this trial. Methods: Patients with relapsed or refractory MCL and measurable disease 2 cm after at least 1 prior treatment regimen were eligible. Patients received 25 mg of lenalidomide orally once daily on days 1–21 of every 28-day cycle. Patients continued therapy until disease progression or toxicity. The 1999 IWLRC methodology was used to assess response and progression. Results: Fifty-four MCL patients were enrolled and were evaluable for response assessment. Median age was 69 years (33–82) and 40 patients (74%) were male. Median time from diagnosis was 3.2 years (0.4–10.4), patients had received a median of 3 prior treatments (1–8), 17 of the patients (32%) had received prior bortezomib therapy (MCL-bortezomib), and 14 (26%) had received a prior stem cell transplant (MCL-stem cell). Response rates are shown in the Table. The most common grade 3 or 4 adverse events were neutropenia (43%), thrombocytopenia (22%) and anemia (11%). Conclusions: This is the second study to demonstrate that lenalidomide oral monotherapy is effective in the treatment of patients with relapsed or refractory MCL, with manageable side effects.

Abstract Lenalidomide plus dexamethasone is effective for the treatment of relapsed and refractory multiple myeloma (MM); however, toxicities from dexamethasone can be dose limiting. We evaluated the efficacy and safety of lenalidomide monotherapy in patients with relapsed and refractory MM. Patients (N = 222) received lenalidomide 30 mg/day once daily (days 1-21 every 28 days) until disease progression or intolerance. Response, progression-free survival (PFS), overall survival (OS), time to progression (TTP), and safety were assessed. Overall, 67% of patients had received 3 or more prior treatment regimens. Partial response or better was reported in 26% of patients, with minimal response 18%. There was no difference between patients who had received 2 or fewer versus 3 or more prior treatment regimens (45% vs 44%, respectively). Median values for TTP, PFS, and OS were 5.2, 4.9, and 23.2 months, respectively. The most common grade 3 or 4 adverse events were neutropenia (60%), thrombocytopenia (39%), and anemia (20%), which proved manageable with dose reduction. Grade 3 or 4 febrile neutropenia occurred in 4% of patients. Lenalidomide monotherapy is active in relapsed and refractory MM with acceptable toxicities. These data support treatment with single-agent lenalidomide, as well as its use in steroid-sparing combination approaches. The study is registered at http://www.clinicaltrials.gov as NCT00065351.

Abstract Abstract 445 Background: Carfilzomib is a proteasome inhibitor that irreversibly binds its target and has a favorable toxicity profile that has shown significant activity in relapsed multiple myeloma (MM), leading to recent FDA accelerated approval. To achieve rapid and deep response in patients eligible for stem cell transplant, we combined carfilzomib with the regimen of cyclophosphamide-thalidomide-dexamethasone (CTD). We recently reported the results of the Phase I component of the trial (in which no MTD was reached) followed by the initial Phase II trial; however, with increasing evidence for the safe and effective use of higher doses of carfilzomib, we now report results from dose escalation extension of the Phase II trial. Methods: Newly diagnosed myeloma patients intended for stem cell transplant were eligible. All patients were treated on a 28 day cycle with Carfilzomib IV Days 1,2,8,9,15,16 (see Table 1 below for dosing per cohort) along with Cyclophosphamide 300 mg/m2 PO Days 1,8,15, Thalidomide 100 mg PO Days 1–28 and Dexamethasone 40 mg PO Days 1,8,15,22. We initially conducted a Phase I run in trial of 6 patients with no DLT observed before expanding to the Phase II portion of the study. The initial phase II regimen is shown below – as no DLTs were observed, we have now fully accrued to the Phase II dose level +1. Treatment was for 4 cycles with expected SCT post induction. The primary endpoint of the trial is the proportion of patients who have ≥very good partial response (VGPR) to treatment. All patients received herpes zoster prophylaxis and ASA daily. Results: A total of 38 patients have been accrued to the trial, 6 in the initial Phase 1, 21 in the initial Phase II, and the remaining at dose escalated cohorts. We are reporting the 27 patients who have completed therapy and will update with the dose escalated cohorts. Median age was 65 (range 27–74) and 52% were female. ISS Stage was advanced (II-III) in 56%. Best overall response rate during 4 cycles of CYCLONE at dose level 0 is 96%: CR 29%, VGPR 46%, PR 21% (1 pt achieved MR). Adverse events of grade 3 or higher at least possibly related to CYCLONE occurred in 12 (44%). Most commonly reported non hematological toxicities (all grades) included fatigue (67%), constipation (56%), lethargy (41%) somnolence (37%), malaise (30%) depressed level of consciousness (22%); however, grade 3/4 toxicities occurring in >5% were uncommon: thromboembolic event 11%) and muscle weakness (7%). Two cases of pneumonia required hospitalization. Eight patients (30%) developed grade 1 sensory neuropathy; no higher grade or painful neuropathy was evident. There were no cardiac events seen in greater than 5% of patients. Grade 3/4 hematological toxicities included neutropenia (15%) and lymphopenia (7%). All patients advancing to SCT successfully collected stem cells. One patient died on study from pneumonia. Conclusion: The 4 drug CYCLONE regimen is highly efficaceous with a response rate after only 4 cycles of 96% (75% ≥VGPR, 29% CR) at the current dosing level of carfilzomib IV 20/27 mg/m2 in newly diagnosed myeloma. Toxicities are manageable, with only grade 1 neuropathy and minimal cardiac or pulmonary toxicity. Increasing the dose of carfilzomib is feasible and updated results of dose escalated cohorts will be reported at 20/36 and 20/45 mg/m2.

Abstract Introduction Hodgkin lymphoma (HL) in patients aged ≥60 years has disproportionately inferior outcomes as compared to HL in younger patients. This can be mostly attributed to treatment-related factors that compromise cure rates. Comorbidities in older patients are associated with higher rates of treatment-related toxicities and can prevent delivery of standard intensity and/or duration of chemotherapy. A retrospective multicenter analysis showed an increased incidence of bleomycin-associated pulmonary toxicity (32%; with a mortality rate of 25%) in HL patients aged ≥ 60 who received ABVD for frontline therapy (Evens 2012). Novel therapeutic approaches with improved efficacy and tolerability are needed for this population. Brentuximab vedotin (ADCETRIS®) is an antibody-drug conjugate that comprises an anti-CD30 antibody conjugated by a protease-cleavable linker to a microtubule-disrupting agent, monomethyl auristatin E. Robust antitumor activity and acceptable toxicity has been demonstrated in HL patients who relapse after conventional chemotherapy or autologous stem cell transplant. A retrospective analysis of patients aged ≥60 years with relapsed/refractory CD30+ lymphomas across 7 single-agent brentuximab vedotin studies showed antitumor activity and clinical response duration consistent with those observed in younger patients (Fanale 2012). Thus, this ongoing phase 2, single-arm, open-label study was initiated to evaluate the efficacy, safety, and tolerability of brentuximab vedotin as frontline monotherapy for HL patients aged ≥60 years (NCT01716806). Methods The population to be enrolled includes ∼30 treatment-naïve patients with classical HL (Stages I–IV). Eligible patients must be aged ≥60 years, have an ECOG status ≤3, and be ineligible for or have declined conventional chemotherapy. Brentuximab vedotin 1.8 mg/kg is administered every 3 weeks by IV infusion. Patients achieving stable disease (SD) or better can receive up to 16 cycles of treatment, after which therapy can be continued for those experiencing clinical benefit. The primary endpoint is objective response rate (ORR) as assessed by the Revised Response Criteria for Malignant Lymphoma (Cheson 2007). Response assessments are performed at Cycles 2, 4, 8, 12, and EOT (including PET at Cycles 2, 8, and EOT). Results Thirteen patients with treatment-naïve classical HL have been enrolled to date. Median age was 75 years (range, 64 to 92) and approximately half of the patients were male (54%). Seven patients (54%) had moderate age-related renal insufficiency at baseline (creatinine clearance ≥30 and<60). Thus far, patients have received a median of 5 cycles of brentuximab vedotin treatment (range, 1 to 11). Four patients discontinued treatment, 2 due to progressive disease, 1 due to a serious adverse event (Grade 3 orthostatic hypotension), and 1 due to patient decision. Of the 11 patients with a response assessment (see table), the ORR was 82% (n=9) and the complete remission (CR) rate was 64% (n=7). For the 10 patients who had interim PET scans after 2 cycles of therapy, the mean decrease in maximum standardized uptake value (SUVmax) between baseline and Cycle 2 was 83%. Cycle 2 PET scans were negative (Deauville Score 1-3) in 36% of patients, and the range of duration of response was 0.1+ to 20.6+ weeks thus far. Treatment-related adverse events (AEs) occurring in ≥15% of patients included neutrophil count decreased, peripheral sensory neuropathy, pruritus, and rash (n=2 each); most events were Grade 1 or 2. Grade 3 treatment-related AEs included neutrophil count decreased, rash, and orthostatic hypotension (n=1 each). No Grade 4 or 5 events have been observed to date. Conclusions In this interim analysis of patients aged ≥60 years with newly diagnosed HL, compelling antitumor activity with single-agent brentuximab vedotin has been demonstrated. To date, a response rate of 82% has been shown in this historically challenging population of patients who either declined or were not eligible for standard chemotherapy. Preliminary safety data demonstrate tolerability in this patient population and the data are consistent with the current safety profile of brentuximab vedotin. Disclosures: Yasenchak: Seattle Genetics, Inc.: Research Funding. Off Label Use: Brentuximab vedotin is indicated for treatment of patients with Hodgkin lymphoma after failure of autologous stem cell transplant or after failure of at least two prior multi-agent chemotherapy regimens in patients who are not ASCT candidates and for the treatment of patients with systemic anaplastic large cell lymphoma after failure of at least one prior multi-agent chemotherapy regimen.

8000 Background: MGCD0103 is a non-hydroxamate, isotype-selective, inhibitor of human HDACs. Abnormal regulation of HDAC activity is associated with malignant disease in humans, and small molecule HDAC inhibitors are a novel drug class with anticancer potential. Their proposed anti-Hodgkin activity is through regulation of aberrant gene expression at the transcriptional level by inhibiting proliferation, inducing apoptosis, and/or initiating differentiation in cancer cells. Methods: A phase II trial of MGCD0103 (110 mg 3x/week in 4- week cycles) is ongoing in patients (pts) with relapsed/refractory Hodgkin Lymphoma (RRHL). The primary endpoint is a composite of objective response and stable disease. Results: As of Dec 15th, 2006, 18 pts out of a planned 12–35 have been enrolled; median age 28 (range: 21–62). All pts were previously treated with autologous and/or allogeneic stem cell transplant. The median number of cycles received to date is 2 (range: 1–4). Seven pts have completed =8 weeks (2 cycles) of therapy and are evaluable for response analysis; 5 of these had tumor reduction ranging between 21% and 70% by CT, which is associated with a significant reduction in FDG-PET activity in 4 pts. Of the 18 pts, 5 have had dose reductions/discontinuations due to: mucositis (n=1); fatigue/nausea/diarrhea (n=1); nausea/vomiting (n=1); fatigue (n=1) and pancreatitis/hypotension (n=1). Significant HDAC inhibition (>20% of total activity), was seen in PBMCs from 7/9 pts with samples. Treatment is ongoing in 14 pts; including those with tumor reduction. Criteria have been met to expand to the second stage of the study (>1 response demonstrated in the first 12 patients). Conclusions: Preliminary results suggest that single-agent MGCD0103 demonstrates significant anti-tumor activity in RRHL and is well tolerated at a Phase II dose of 110mg in this ongoing trial. No significant financial relationships to disclose.

18179 Background: Because elderly pts may tolerate platinum-based combination chemotherapy poorly, single-agent chemotherapy is selected for the treatment regimen. However, retrospective subgroup analyses have consistently indicated that elderly pts indeed benefit from platinum-based combination chemotherapy as well as their younger counterparts. This phase II study evaluated the efficacy and safety of carboplatin-gemcitabine combination chemotherapy in elderly pts with advanced NSCLC. Methods: Fifty-four pts aged more than 70 years old (median, 77; range, 70–88) with previously untreated advanced NSCLC were enrolled on this trial. Additional criteria included the presence of measurable lesions, an Eastern Cooperative Oncology Group performance status of 0 or 1, and adequate organ function. Pts received carboplatin at an area under the curve of 4 mg/ml/min on the first day and gemcitabine at 1000 mg/m2 on the first and eighth day of consecutive 3 week periods. The primary endpoint was to determine the objective response rate of this platinum-doublet regimen. The RECIST criteria were used to measure response. Results: Enrolled pts included 15/39 with stage IIIB/IV diseases. Fifty-one out of enrolled pts were eligible for efficacy and safety analyses. The median number of treatment cycles was 4 (range, 1–7). Fifteen partial responses (response rate: 29%) were obtained. The median TTP was 118 days. Hematological toxicities of grade 3/4 included leukopenia (46%), neutropenia (72%) and thrombocytopenia (50%). Non-hematological toxicities of grade 3/4 included nausea (6%), appetite loss (7%), fatigue (7%) and infection (9%). Conclusions: The combination carboplatin-gemcitabine at these doses has shown activity with a favorable toxicity profile for fit elderly pts with advanced NSCLC.

e19074 Background: S-1 is a novel oral 5-fluorouracil derivative that exhibits obvious activity against various tumor types including NSCLC. However, the effects of S-1 against SCLC have not been reported. The present phase II trial assesses the efficacy and safety of S-1 in previously treated SCLC patients. Methods: Eligible patients had pathologically documented SCLC that relapsed after platinum-based chemotherapy, ECOG performance status (PS) 0–2, and adequate bone marrow, kidney and liver function. Patients with untreated or symptomatic brain metastasis were excluded. Treatment comprised the oral administration of S-1 at 40 mg/m2 twice each day for 28 days every 6 weeks. The primary end point was the objective tumor response rate (RECIST). Secondary endpoints included progression-free survival and overall survival. Results: Twenty-six evaluable patients were enrolled (Simon's two-stage optimal design; α = 0.1; β = 0.1; P0 = 0.05; P1 = 0.25) with the following characteristics: male: female, 22/4; median age, 68 (33 - 79) y; PS0–1, n = 21; PS2, n = 5. The median number of prior treatment regimens was 2 (1–3). S-1 was administered for a mean of 1.3 cycles (1 - 5). One patient (3.8%) partially responded, 10 (38.5%) had stable and 15 (57.7%) had progressive disease. The overall response rate was 3.8% and the disease control rate was 42.3%. The median time to progression was 33 days. The median survival time was 8.0 months and the 1-year survival rate was 23%. This regimen was well tolerated. The common grade 3/4 toxicities included neutropenia (7.7%), leukopenia (7.7%), anemia (7.7%), hyponatremia (7.7%), rush (7.7%), infection (7.7%), and diarrhea (3.8%). None of the patients developed febrile neutropenia and no deaths were attributed to treatment. Conclusions: S-1 is well tolerated but has low activity as a single agent in previously treated patients with SCLC. No significant financial relationships to disclose.

435 Background: Given a lack of clinical information on therapeutic efficacy of agents following progression after vascular endothelial growth factor (VEGF) tyrosine kinase inhibition (TKI) and mammalian target of rapamycin (mTOR) inhibition in metastatic renal cell carcinoma (mRCC), we investigated the activity of single agent bevacizumab (B) in this setting. Methods: We conducted a retrospective analysis of single agent B-treated patients with mRCC in the second/third line setting, and identified 21 subjects who met inclusion criteria. The primary endpoint was progression-free survival (PFS). Baseline characteristics, survival, response efficacy outcomes, and toxicities were assessed and summarized. Results: 21 patients (15 women/6 men) were treated with B at a dose of 5 mg/kg/week, dosed q2-3 weeks. Median age was 63, 80% were white, 14% black; 80% had clear cell histology. Median time from diagnosis to B therapy was 3 years (range 1-18); 100% had prior VEGF TKI therapy; 43% had prior mTOR inhibitor; 43% had prior IFN and 19% prior IL-2; median number of prior therapies was 3 (range 1-7); 100% were considered Motzer intermediate risk. Median PFS on B for all subjects was 4.4 mo (95% CI 2.8-9.6) and median OS was 19.4 mo (95% CI 9.9-NR) from start of B therapy. ORR was 2 CR/PR (9.5%), 11 SD (52%), 5 PD, 3 NE. For subjects treated with prior VEGF and mTOR inhibitors, median PFS and OS were 4.4/13.2 mo. Toxicities were as expected and severe adverse events included grade 3-4 fatigue (6), grade 3-4 dehydration (5), and grade 4 failure to thrive (2), grade 4 constipation (2), and grade 3 muscle weakness (2). Conclusions: Single agent B therapy has acceptable toxicity and moderate disease stabilizing activity in selected patients with mRCC who have failed prior VEGF TKI and mTOR inhibitor therapy, and suggests a benefit to continued ongoing VEGF inhibition. Further prospective study of B alone, in combination with mTOR inhibition, or with alternative targeted agents is warranted.

Abstract Background: mTOR inhibition has been shown to be effective in various subtypes of malignant lymphomas. In relapsed MCL a phase III trial could prove superiority of Temsirolimus to standard options. Furthermore, in patients with follicular and diffuse large B-cell lymphoma, promising response rates could be observed (Smith et al, JCO 2010). Whereas combination to single agent Rituximab (R) improved efficacy (Ansell et al, Lancet Oncology 2011), there is limited information of the feasibility and efficacy in combination with chemotherapy. Bendamustine (B) has been shown to be effective in various lymphoma entities and has a beneficial side effect profile (Rummel et al, JCO, 2005). In the phase I of this trial, we have established that 50mg of Temsirolimus given 3 times weekly in a four week cycle could be safely added to BR (Hess, Leukemia, 2015). Here we report for the first time combined results of phase I and II of this trial. Methods: this is a multicenter, national, prospective trial. Inclusion criteria: patients were eligible if they had histologically proven FL or MCL, 1-3 prior treatment lines, no curative option available, no refractoriness to Bendamustine, measurable disease, ECOG < 3, sufficient bone marrow reserve, no severe concomitant diseases and given informed consent. Treatment consisted of Bendamustine 90mg/m² day 1-2, Rituximab 375mg/m² day 1 and Temsirolimus 50 mg day 2, 8, 15 of a 28d cycle. A total of 4 cycles was planned with interim staging after 2 cycles. Results: Overall 34 patients (pts) have been included until now (15 pts phase I, 19 pts phase II). Concerning clinical characteristics, median age was 71 years, with 25 MCL and 9FL, and a median number of 2 pretreatments (1-3). Overall the treatment was well tolerated, and toxicity was predominantly hematologic. In 118 evaluable cycles of chemotherapy the following hematologic grade 3 / 4 toxicities were noted: leukopenia (11 pts, 32%), neutropenia (8 pts, 24%), and thrombocytopenia (7 pts, 21%). Non-hematologic grade 3 / 4 observed in at least two patients were angioedema and decrease in blood potassium, infection, metabolic (4 events). AE's of special interest: pulmonary: rate of cough (4; 12%) and pneumonitis (1; 3%); gastrointestinal: diarrhea (6; 18%), nausea (13, 38%); general: fatigue (16; 47%), mucositis (13, 38%); bleeding: epistaxis (4; 12%), which all were predominantly grade 1 or 2. Response: currently, best responses were 8 CR (31%), 16 PR (62%) and 2 SD (8%) in 26 patients evaluable so far. Updated results will be presented at the meeting. Overall responses were 94% in MCL (7 CR, 10 PR, 1 SD) and 88% in FL (1 CR, 6 PR, 1 SD). After a median follow up of 13 months (mean: 21 months) median PFS is 18.6 months for the entire cohort, with 22 months for MCL and not reached in FL. Summary: In this ongoing phase II trial 50mg Temsirolimus (day 1,8,15) in combination with Bendamustine and Rituximab was well tolerated and feasible. A moderate dose of Temsirolimus to standard chemotherapy might be the optimal way to achieve the maximum efficacy with mTOR inhibitors; in fact excellent response rates suggest an additive effect of mTOR inhibition to BR. Even after the BTK inhibitor Ibrutinib has entered the clinical arena of MCL, this combined treatment represents a valuable additional option especially for patients with relapsed MCL Disclosures Hess: Pfizer, Janssen, Roche, Mundipharma: Honoraria, Research Funding; Janssen, Roche, , Celgene, Novartis: Consultancy.
