Abstract Background: Fludarabine-mitoxantrone-dexamethasone-rituximab (FND-R) is a combination chemotherapy with significant activity in untreated and relapsed indolent B-cell lymphoma patients (pts). Pixantrone is a novel aza-anthracenedione that has no delayed cardiotoxicity in animal models and has single agent activity in NHL. We conducted an outpatient phase I/II trial, to define the recommended dose (RD) of pixantrone when substituting for mitoxantrone in the FND-R regimen, and the safety and efficacy of this regimen in pts with relapsed or refractory indolent NHL. Methods: Pts received pixantrone with fludarabine (25mg/m2/day, days 1–3), dexamethasone (20mg/day, days 1–5), and rituximab (375mg/m2/day on day 1) in a 28 day regimen (FPD-R). Based on previous single agent clinical studies, the starting dose of pixantrone was defined as 80mg/m². The RD was established to be 120mg/m2 and the protocol was amended to treat patients in the phase II part. Results: 9 pts (6 males) with a median age of 65 years (range 41–78) were included in the dose-finding part of the study. Following the protocol amendment, 23 pts (11 males) of WHO performance status 0–1, median age 61 (range 32–78) have been enrolled in the currently ongoing phase II part. Pathology included SLL/CLL, follicular grade I, follicular grade II, MALT, marginal cell, and other indolent B-cell lymphomas. All pts had received a prior anthracycline-containing regimen (median number 1, range 1–4). The study regimen was well tolerated; median number of courses received was 5 (range 2–8). Grade 4 toxicities were neutropenia in 10 pts, leukopenia in 5 pts, and thrombocytopenia in 1 pt. No clinically significant cardiac events or decreases in LVEF ≥20% were noted. However 4 pts went below 50% LVEF including 1 pt who was below 50% at baseline. Non-hematologic adverse events were primarily grade 1 or 2 in severity. Response rate was 75% for the 20 pts evaluable for response, with 11 (55%) complete remission [7 confirmed (CR), 4 unconfirmed (CRu)], and 4 (20%) partial remission (PR). Two responders went onto bone marrow transplant (BMT): one had a CRu and one a PR. A third patient was pending BMT after CR. At a median follow-up of 345 days, the median duration of response has not been reached, as only two pts have progressed: the first progression occurred at 113 days, and the second pt progressed at 699 days. The remaining pts are still in remission. Conclusions: The RD of pixantrone in the FPD-R regimen is 120mg/m2. The primary toxicity is hematologic. The regimen can be given on an outpatient basis, is associated with major responses, and is very well tolerated in relapsed and refractory indolent NHL pts.

Abstract Background: Pixantrone (P) is a novel aza-anthracenedione that has substantially less delayed cardiotoxicity than either doxorubicin or mitoxantrone in animal models, with greater efficacy than either against murine lymphoma and leukemia in in vivo models. In patients (pts) with relapsed or refractory indolent NHL, P + rituximab (R) delayed the time to tumor progression compared with single agent R (395 vs. 245 days, log rank p-value <0.001). In addition, the overall response rate was higher in the P+R arm (75%, CR 35%) compared with single agent R-treated pts (ORR 33% and CR 11%). Fludarabine (F)-mitoxantrone (N)-dexamethasone (D)-rituximab (FND-R) is an alternative active combination in indolent B-cell lymphoma pts. The current study substituted P for N in the combination therapy (FPD-R), with the objective of determining the recommended dose (RD) of P and the safety and efficacy of FPD-R in pts with relapsed or refractory indolent NHL. Methods: Pts received P (day 2) with F (25 mg/m2/day, days 2–4), D (20 mg/day, days 1–5), and R (375 mg/m2/day, day 1) in a 28 day regimen. This was a dose escalation study; once the RD was determined, the next cohort of pts was to be treated at that dose. Results: Three pts were treated with P at 80 mg/m2 and 25 pts at 120 mg/m2, which was the RD determined in the Phase I portion of the study. The median age was 63 (range 32–78); all pts had WHO performance status 0–1. All pts had received at least one prior chemotherapy regimen (median 1, range 1–4). The median number of cycles received was 5 (range 1–8). The overall response rate (response of any duration) was 89% for 27 evaluable pts, with 17 (63%) complete responses (CR), 2 (7%) unconfirmed complete responses (CRu), and 5 (19%) partial responses (PR). Seventy percent of pts experienced a CR/CRu/PR that lasted at least 8 weeks, with a median duration of response of 25 months, (range 2.4 to 43). Grade 3/4 hematologic toxicities were neutropenia 23 (82%), thrombocytopenia 6 (21%), febrile neutropenia 3 (11%), and anemia 1 (4%). Non-hematologic adverse events were primarily grade 1 or 2 in severity. A total of 7 of 28 (25%) pts evaluable for safety had a decline in LVEF ≥ 10% to ≤ 20%. No pt had a decline in LVEF > 20 %. In 4 pts the decline in LVEF was transient and returned toward baseline with continued follow-up. Five of the 7 pts with a decline in LVEF were asymptomatic. Two pts reported transient shortness of breath with spontaneous resolution without treatment. No episodes of CHF were reported. Conclusions: The RD of pixantrone in the FPD-R regimen is 120 mg/m2. The primary toxicity is hematologic; no serious cardiotoxicity was observed. This treatment is highly active and is associated with major, durable responses. The regimen can be given on an outpatient basis and is well tolerated in relapsed and refractory indolent NHL pts.

Abstract Certain normal and malignant B-cells rely upon “tonic” B-cell receptor (BCR)-mediated survival signals. BCR signaling induces the phosphorylation of the associated Ig alpha and beta proteins and the recruitment and activation of spleen tyrosine kinase (SYK); thereafter, SYK initiates downstream events and amplifies the original BCR signal. A subset of DLBCL exhibits coordinate overexpression of BCR pathway components, including SYK, and relies upon tonic BCR signaling. FosD is an orally available inhibitor of SYK under development for rheumatoid arthritis, and has demonstrated significant in vitro activity against BCR-dependent NHLs. We have performed the first clinical trial of the oral SYK inhibitor, FosD, in patients (pts) with a variety of relapsed or refractory B-cell non-Hodgkin’s lymphomas. We first enrolled 13 pts in a Phase I component, exploring two dose levels (200 and 250 mg BID) of FosD. Pts (Follicular [FL], 5; CLL/SLL, 2; mantle [MCL], 3; DLBCL, 3) were heavily pretreated. On the first day of FosD dosing at 200 mg and 250 mg, the maximum plasma concentrations were 668 ± 258 ng/mL and 1020 ± 781 ng/mL, and the AUC0–4 estimates were 1800 ± 602 ng*h/mL and 2590 ± 1900 ng*h/mL, respectively. Plasma concentrations increased approximately 2-fold with continued administration, but beyond Day 29 there was no apparent change in FosD concentrations measured over time. Dose limiting toxicity in Phase I was neutropenia; and 200 mg BID was chosen for Phase II evaluation. We then enrolled 68 pts with relapsed/refractory NHL in 3 separate disease cohorts: DLBCL (23); FL (21) and other B-cell NHL (24) including SLL/CLL (11), MCL (9) marginal zone/MALT (3) and lymphoplasmacytic NHL (1). The median age of pts in phase II was 61 (range 41–87); pts received a median of 5 prior therapies, including ASCT (16; 12 with DLBCL) and radioimmunotherapy (8). FosD was overall very well tolerated; there were 4 cases of febrile neutropenia reported. Eight pts required dose modification for neutropenia (2), hypertension (2), liver function test abnormalities (2), fever (1) and mucositis (1). Six pts withdrew before initial response evaluation (AE, 5; noncompliance, 1). Best responses by disease were: DLBCL 21% (4PR; 1CR); SLL/CLL 54% (6PR); FL 10% (2PR); MCL 11% (1PR). Stable disease was observed in an additional 23 patients, including 12 with FL, 4 with DLBCL, 4 with MCL, 2 with CLL/SLL and 1 with MALT. As of 7/15/08, 16 pts were treated for more than 200 days, and 14 pts remain on study. Median PFS is 4.5 months, and only 5 pts have died (4 with DLBCL of disease progression and 1 with CLL of infection following therapy). Several pts with CLL/SLL experienced a transient increase in circulating lymphocytes in the setting of responding nodal disease. Of the 6 responding pts with CLL, Zap-70 status was positive (3), negative (1) and unknown (2); cytogenetics were trisomy 12 (1), del13 (1), normal (1), complex (1) and unknown (2). We conclude that disrupting BCR-induced signaling by inhibiting SYK kinase represents a safe and well-tolerated novel therapeutic approach to NHL. In addition to significant responses in DLBCL and CLL/SLL, prolonged stable disease was observed in pts with FL. FosD should be developed further, as a single agent and in rational combinations, for BCR-dependent B-cell NHLs.

6500 Background: MGCD0103 is a novel inhibitor of human histone deacetylases (HDACs), with selectivity for the cancer-associated isoforms of class I HDACs. Deacetylation of histones by HDACs is postulated to inactivate tumour suppressor genes leading to neoplastic transformation, and therefore inhibition of this enzyme may result in antineoplastic activity. Methods: To study the safety and activity of MGCD0103, we have developed a phase I open-label dose escalation study of MGCD0103 administered orally, three-times weekly in patients with leukemia or MDS, with the primary endpoints being the determination of the maximum tolerated dose (MTD) and the pharmacokinetic (PK) and pharmacodynamic (PD) characteristics of MGCD0103. Eligibility criteria included appropriate performance status and renal and hepatic functions. Patients with relapsed/refractory leukemia or MDS and older patients with untreated AML/MDS were eligible. Results: Twenty patients have been enrolled at four dose levels (20, 40, 80 and 60 mg/m2) so far. Their characteristics are: median age 60 years (range 33–76); the majority of patients so far treated have AML; median number of prior therapies is 1 (range 0–3). Most patients had complex cytogenetics. MGCD0103 has been well tolerated at doses below 80 mg/m2. The MTD has been reached, with 3 out of 4 patients at a dose of 80 mg/m2 developing grade 3 toxicity, mainly fatigue, nausea, vomiting or diarrhea. Grade 2 toxicities include anorexia, constipation, dehydration. The median number of courses is 1 (range 1 to 6). As of January 2006, 7 patients are on study. PK evaluations show dose-dependent exposure. Analysis of peripheral blood cell HDAC activity indicates that HDAC inhibition occurs in all patients in a dose-dependent manner. Two patients with multiple relapsed/refractory acute myelogenous leukemia, and one with MDS have achieved a complete marrow response (blasts less than 6%). Of importance, maximal HDAC inhibition was observed in those patients at the time of best response. Conclusions: Single-agent MGCD0103 has clinical activity and is well tolerated at doses below 80 mg/m2 orally three times a week in patients with advanced leukemia. No significant financial relationships to disclose.

5039 Background: Combined mTOR and VEGF blockade is a potentially promising and rational strategy for the treatment of advanced RCC. We previously reported the phase I safety and efficacy results of CCI 779 (C) +bevacizumab (B) n RTKI naïve stage IV RCC patients (pts) (J Clin Oncol. 2007;25[18S Suppl]:5034). We now report the interim results of the phase 2 study of C+B in RTKI refractory RCC patients. Methods: Design: Open label, phase I/II study of C+B in advanced RCC pts. Patients with measurable stage IV RCC with a component of clear/conventional cell type, performance status 0–2 and good organ function were eligible. Up to two prior treatment regimens were allowed (at least one prior RTKI). Phase II dose was C = 25 mg IV weekly and B = 10 mg/kg every 2 weeks repeated in 4 week cycles. The primary objective of the phase II portion was to assess the proportion of patients who were progression-free 6 months after study entry. Secondary objectives were assessment of response rates and toxicity. Accrual goal = 40 pts. Results: Thirty-five pts have been enrolled into the phase 2 portion to date with 4 pts ineligible. Twenty-five pts are evaluable for response assessment and 29 pts are evaluable for toxicity. Baseline characteristics (N: 35): M/F: 28/7; Number of met. sites: 1/2/3+: 15/9/11; prior nephrectomy: 31; Number of prior therapies: 1 = 29; 2 = 2. Most common (>5%) Gr 3–4 AEs (N = 29) included fatigue (6), hypercholesterolemia (2), hypertriglyceridemia (2), anorexia (2), rash (2), and anemia (2). Responses were: PR/SD/PD = 4 (16%)/18 (72%)/3 (12%). Median number of cycles administered was 4. Six month progression free rates will mature by may 2009. Conclusions: C+B combination at the recommended phase 2 doses is feasible and well tolerated. Clinical benefit rates (PR/SD) in RTKI refractory RCC patients (88%) are encouraging. Data on 6 month progression-free rates are expected to mature in 4/09. Updated data on safety, response rates, and 6-month progression free rates will be presented on all evaluable patients. Correlative studies on available plasma, serum and tumor samples for angiogenic and molecular biomarkers are underway. Supported by N01-CM62205, R21 CA 119545–02, and Commonwealth Foundation.

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.

8065 Background: Novel B-cell targeting agents, including monoclonal antibodies such as rituximab, are among recent advances in treatment of B-cell malignancies. New approaches are needed for patients progressing after rituximab-based therapies. MEDI-551 is an afucosylated monoclonal antibody targeting CD-19, a B-cell restricted transmembrane protein with enhanced affinity and antibody-dependent cellular cytotoxicity. Methods: Pts with relapsed or refractory follicular lymphoma (FL), diffuse large B-cell lymphoma (DLBCL), chronic lymphocytic leukemia, or multiple myeloma received single agent MEDI-551 at dosages ranging from 0.5 mg/kg to 12 mg/kg via intravenous infusion over 28-day cycles; cohorts 1-6 received 0.5, 1, 2, 4, 8, and 12 mg/kg, respectively. Results: 25 pts were enrolled in the phase I portion Jun 2010–Aug 2011. No maximum tolerated dose (MTD) was achieved. Most AEs were grade 1/2 with dose-independent frequency and severity (Table). Six pts had grade 3 toxicities including tumor lysis syndrome, infusion reaction, thrombocytopenia, and neutropenia, or grade 4 neutropenia. No grade 5 AEs were seen. All pts recovered. Three partial responses (PR) and 2 complete responses (CR) were seen in DLBCL and FL pts at 0.5, 4, and 8 mg/kg. Activity included a CR lasting 9 mo. in a FL pt in cohort 1, who is currently being retreated with MEDI-551 on relapse. Conclusions: MEDI-551 demonstrated a safety profile warranting further study and showed no MTD reached at the highest dose studied. Anti-tumor activity is suggested by the responses achieved across dose levels. Phase II is currently enrolling subjects. This study is funded by MedImmune, LLC. [Table: see text]

7521 Background: MOR208, an Fc-enhanced, humanized, anti-CD19 monoclonal antibody has shown single agent activity in patients (pts) with R-R DLBCL and encouraging activity when combined with LEN in the phase II L-MIND study. Here we report an update with primary endpoint and subgroup analyses (cut off June 5, 2018). Methods: Key inclusion criteria were adequate organ function, ≤3 prior lines of therapy, including ≥1 anti-CD20 therapy, and ineligibility for stem cell transplantation. Treatment comprised up to 12, 28-day (d) cycles (C) of MOR208, 12 mg/kg IV, q1w C1–3 (loading dose on d4 of C1), and q2w C4–12 + LEN 25 mg PO d1–21, C1–12. Pts progression-free after 12 C received MOR208 q2w until progression. The primary endpoint was independent review committee (IRC)-assessed ORR as per Cheson 2007 criteria. Results: Recruitment is complete (N = 81): median age 72 years (range 41–87), median of 2 prior therapies, 19 (23%) of pts had early relapse (≤12 months [mo] from diagnosis), 32 (40%) were rituximab (RTX) refractory (no response to or progression during or within 6 mo of a prior RTX therapy), 34 (42%) were refractory to their last therapy, 21/40 (26%/49%) pts had non-germinal center B cell-like (GCB)- / GCB-DLBCL, and 42 (52%) had an International Prognostic Index (IPI) of 3–5. MOR208 + LEN therapy was well tolerated; 72% of pts stayed on a LEN dose of ≥20 mg/day. Treatment-related serious adverse events, mainly infections (10%) or neutropenic fever (5%), occurred in 17% of pts. Investigator (INV)-assessed complete response (CR) and partial response rates were 33% and 25%, respectively, giving an ORR of 58%, comparable to the IRC assessment (ORR 54%; CR 32%). ORR was 46% in pts with ≥2 prior therapies, 59%/56% in rituximab- / last treatment-refractory pts, 58% in early relapse pts, 57% in pts with a baseline IPI of 3–5, and 71% in pts with non-GCB- vs 53% with GCB-DLBCL. INV-assessed median PFS and OS (ITT analysis) were 16.2 mo (95% CI: 6.3–NR) and not reached (95% CI: 18.6–NR), respectively. Conclusions: MOR208 + LEN shows encouraging activity including a durable PFS in R-R DLBCL, and in pt subgroups with poor prognosis. Clinical trial information: NCT02399085.

TPS8073 Background: Response rates to salvage immunochemotherapy in patients with DLBCL relapsing after or refractory (R/R DLBCL) to front line therapy remain unsatisfactory. Lenalidomide (Len) has significant single agent activity in relapsed/refractory DLBCL. The addition of lenalidomide (Len) days 1-7 to rituximab plus ifosfamide-carboplatin-etoposide (RICE) was shown to be feasible with promising efficacy in phase 1b study (Feldman T, et al. BJH, 2014). We developed phase I/II study to evaluate the safety and efficacy of the addition of Len (extended to 14 day schedule) to RICE (R2-ICE) for R/R-DLBCL patients who are candidates for stem cell transplant. Methods: The phase I portion was designed to determine the maximally tolerated dose Len in combination with RICE using the standard cohort 3+3 design. The escalation dose levels were 15 mg and 20 mg daily x 14 days. Prophylactic aspirin and growth factor support is mandatory. After 2 cycles of therapy response is evaluated with a PET/CT scan; the responding patients are eligible for 1-2 additional cycles of R2ICE as a bridging before HDC/SCT. The estimated overall response rate for two cycles of R-ICE in R/R DLBCL to RCHOP was estimated to be approximate 45%. We hypothesize that the addition of lenalidomide in the relapse setting could increase the overall response rate by approximately 20%. The one-stage design with an interim analysis being utilized in phase 2 requires 45 evaluable patients (one sided alpha = 0.09, power 90%). For Phase I, all types of B-cell lymphomas were eligible. For phase II portion only DLBCL patients are eligible per central pathology review. Other eligibility criteria include: received one line of previous anti-lymphoma therapy, ≥ 2 weeks from completion of prior anti-lymphoma therapy, candidate for HDC and SCT, adequate organ (creatinine clearance ≥ 60ml/min by Cockcroft-, total bilirubin ≤ 2 × ULN) and bone marrow function (ANC) ≥1500/mm3; platelet count ≥75,000/mm3). The use of steroids and/or rituximab up to 1 week prior to registration for management of symptoms is allowed. 9 patients cleared phase 1 without DLT and dose of 20 mg days 1 -14 was recommend for phase 2 part (RP2D) of the study. The phase 2 study passed interim futility analysis and accrual continues. Correlatives include cell of origin by Nanostring, Myc/bcl2 expression and by FISH and minimal residual disease. PET scans are centrally reviewed including metabolic tumor volume. Clinical trial information: NCT02628405 .

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.
