Abstract Abstract 2376 Poster Board II-353 Background: Patients with relapsed or refractory CLL/SLL and patients with mantle cell lymphoma (McL) have a poor prognosis. Overall response rate (ORR) to salvage therapy for refractory patients is approximately 10-30%, and survival benefit with current treatment approaches is limited. Phase II studies of single agent lenalidomide in patients with relapsed or refractory CLL revealed an ORR of 32-58% (7-17% CR), depending on treatment dose, scheduled used and duration of treatment with lenalidomide. In patients with refractory or relapsed McL, lenalidomide treatment resulted in an ORR of 53% (CR 20%, PR 33%), and a 14-month median duration of response (Habermann et al 2009). Recent in vitro studies have shown that lenalidomide enhances the rituximab-induced killing of NHL cell lines and B-CLL cells via ADCC by restoring the defective T-cell and NK-cell mediated ability to form immune synapses to exert tumor cell cytotoxicity. Methods: Patients with relapsed or refractory CLL/SLL or McL received oral lenalidomide via dose escalation as follows, 2.5 mg on days 1-7, 5mg on day 8-14 and 10mg on day 15-21 followed by 7 days of rest in 28-day cycle; for cycle 2 and beyond 20mg was given on day 1-21 on a 28 day cycle. Rituximab was dosed at 375mg/m2 IV weekly for 4 weeks starting on day 15 of cycle 1. Treatment was continued until disease progression or toxicity. All patients were given allopurinol 300mg orally twice per day starting 3 days prior to first dose of lenalidomide. CT scans, and bone marrow biopsies were done every 2 months to assess for response. Primary objectives were overall response rate (CR+PR) and safety and tolerability of the combination regimen. Results: 17 patients were enrolled on study (13 patients with CLL/SLL and 4 patients with McL). Median number of prior chemotherapies was 3 (range 1-5). Median age was 64 years (range 42-80). Among patients with CLL, the most common cytogenetic abnormalities were trisomy 12 (isolated n=3, associated with other abnormalities n=4), del11q (isolated n=1, with others n=3), isolated del13q (n=1), complex cytogenetics with 3 or more abnormalities (n=4 including 1 patient with del 17p). Responses were assessed every 2 months after initiation of therapy. Response rate for 13 evaluable patients (10 with CLL and 3 with McL) relative to months on treatment with lenalidomide are summarized in the table. Although all responses were PR, the rate of PR improved with continued therapy suggesting increased responses with a longer duration of treatment with lenalidomide. Currently, 7 patients are still receiving active treatment on study, all with CLL (3 achieved a PR and 4 have SD). Of the 4 patients with McL enrolled on study, 1 achieved a PR after 2 months of therapy; 1 achieved SD after 2 months of therapy with a sustained SD after 6 months; 1 patient achieved SD after 2 months, but progressed after 6 months on treatment. The regimen was well tolerated. Most common (>5%) toxicities include neutropenia (35% grade 3, 6% grade 4), fatigue (17% grade 1-2, 6% grade 3), tumor flare (12% grade 2, 12% grade 3), acute renal insufficiency (6% grade 1, 12% grade 3), rituximab related infusion reactions (6% grade 2, 6% grade 3), flu-like symptoms (6% grade 2, 6% grade 3), venous thromboembolic disease (6% grade 2, 6% grade 3), infections (11% including 1 patient with fatal endocarditis), and hypercalcemia (11% grade 4). Correlative studies are ongoing. Conclusions: The combination of lenalidomide with Rituximab is a promising combination regimen in CLL patients with very poor prognosis who have undergone multiple lines of therapy. This treatment combination appears tolerable with observed events consistent with the use of these two agents in other studies. Further investigation is warranted, possibly in the front line setting and in combination with other agents. Disclosures: Lancet: Celgene: Research Funding.

Abstract SDX-105 (Treanda™, Bendamustine HCl) is an alkylating agent that may exert its anti-tumor activity via mitotic catastrophe, an apoptosis-independent cell-death pathway, as well as, through apoptosis. Its cytotoxic potency is unattenuated in chemotherapy-resistant lymphoma cell lines. We initiated a multi-center Phase II trial to investigate the safety and efficacy of SDX-105 in patients with rituximab-refractory, relapsed indolent or transformed B cell NHL. Patients must have pathologically-confirmed disease that has been demonstrated to be rituximab-refractory (no response or progression within 6 months) or must be intolerant of rituximab. Other requirements include measurable disease, adequate renal, hepatic and bone marrow function (ANC ≥1K/mm3, platelet ≥ 100K/mm3, except in cases of >50% NHL in bone marrow), up to 3 prior chemotherapies, and no prior allogeneic transplant. Patients receive SDX-105, 120 mg/m2 IV over 30–60 min, days 1 and 2, every 21 days. Grade 4 hematologic toxicity during a cycle results in dose reduction for subsequent cycles (to 90 mg/m2 and then to 60 mg/m2). Patients achieving stable disease or better after 6 cycles may receive up to 6 more cycles. 49 patients have been accrued to date with data available on the first 15 patients. The median age is 69 yrs (range 47–84), 47% male, median 6 yrs since diagnosis with NHL. Histologies: 10 follicular (6 Grade 1, 3 Grade 2, 1 Grade 3), 2 SLL, 1 marginal zone and 2 transformed NHL. Other features include: 93% Stage III/IV, 20% with B symptoms, 87% with extranodal disease, median 2 prior chemotherapies with 40% not responding to last chemotherapy. 4 patients have required dose reduction to 90 mg/m2 and 2 patients have withdrawn prior to completing 6 cycles due to treatment-associated toxicity. The current overall response rate (ORR) based upon best response in the intent-to-treat population is 80% (CR/CRu 20%, PR 60%). Overall 73% of patients experienced a related non-hematologic adverse event (AE), of which 20% were Grade 3 and 0% Grade 4. The most frequent AEs were nausea (40%), vomiting (27%), fatigue (33%), anorexia (20%), and constipation (20%). Alopecia was not observed. Grade 3 or 4 hematologic toxicity was seen in 53% (neutropenia), 20% (thrombocytopenia), and 13% (anemia) of patients. 4 patients experienced serious AEs, including 1 patient with baseline renal insufficiency who died on study from renal failure and pulmonary edema; other events include admissions for fever and anemia, urinary tract infection, and dehydration. Based upon these preliminary findings, SDX-105 demonstrates a high overall response rate with acceptable hematologic toxicity and modest non-hematologic toxicity in a relapsed lymphoma patient population, many of whom are refractory to rituximab-chemotherapy combinations. An additional study evaluating the combination of SDX-105 and rituximab in patients with relapsed indolent NHL who are rituximab-sensitive is also ongoing.

Abstract Background: Bortezomib as a single agent has known efficacy in the treatment of relapsed multiple myeloma. The overall response rate (CR+PR+MR) was 35% in the SUMMIT study and 46% in the APEX study. In-vitro studies including our own have demonstrated potent synergy with other chemotherapeutic agents such as melphalan. It therefore follows that responses to bortezomib may be further improved by the combination of such drugs. Aims: The primary objectives of this Phase I/II study was to assess the safety, tolerability and response rates in patients with relapsed multiple myeloma; secondary objectives being time to progression (TTP) and overall surival (OS). Methods: This was a multi-centre, non-randomised trial for patients with relapsed myeloma. Patients received bortezomib 1.3mg/m2 on days 1,4,8 and 11 of each 28 day cycle with melphalan on day 2 at increasing dose levels. This was initially at 10mg/m2, but due to cytopenias subsequently at 2.5 and 5mg/m2 (levels 1a, 1 and 2) and we plan to escalate to 7.5mg/m2. Up to 8 cycles were given with dexamethasone added for stable or progressive disease after 4 or 2 cycles respectively. Responses were determined by EBMT criteria. Results: To date, 18 patients have been enrolled (12 male 6 female; median age 60 [range 44–73]; median number of prior therapies 3 [range 1–5] of which 17 have had at least one autologous stem cell procedure with high dose melphalan; 10 prior thalidomide and 2 prior bortezomib). 12 patients received melphalan at 10mg/m2 but due to unacceptable delays predominantly due to thrombocytopaenia, subsequent treatment levels commenced at 2.5mg/m2. The median number of cycles completed thus far is 4 (range 0–8) and of the 16 evaluable, the overall response rate (CR+PR+MR) across all treatment levels was 50% rising to 75% following the addition of dexamethasone as per protocol. At level 1a (melphalan 10mg/m2 ,N=12, median number of cycles completed =5) the best responses (with dexamethasone as indicated) were: 1CR, 1 VGPR, 5 PR, 2 MR; at level 1 (melphalan 2.5mg/m2, N=4) 1 PR, 2 MR (after 2 cycles only). The median time to any response was 1 cycle (range 1–3 ). Three patients have progressive disease, but the median TTP and OS have not yet been reached (median follow-up 3 months). Non-haematological toxicities have been modest with 7 SAEs reported of which only 1 was possibly drug related (myocardial infarction), and 4 episodes of Grade 3 neuropathy (2 resulting in study withdrawal). The commonest grade 3–4 haematological toxicity was thrombocytopaenia (N=10) complicated by bleeding in one patient, followed by neutropenia (N=6). Summary: The combination of bortezomib and intravenous melphalan can be given safely to patients with relapsed multiple myeloma and dose escalation is ongoing. Myelosupression was the commonest grade 3–4 adverse event. A response rate of 50% was seen, which was further improved to 75% with the addition of dexamethasone. This combination may therefore result in higher responses than single agent bortezomib in heavily pretreated patients.

Abstract INTRODUCTION: Previous studies have demonstrated the clinical activity of the mTOR inhibitor RAD001 in low- grade lymphomas. Our preclinical studies demonstrated activity of mTOR inhibitors in Waldenstrom Macroglobulinemia (WM) cell lines and patient samples. This phase II study aimed to determine safety and activity of the oral mTOR inhibitor RAD001 (Novartis Pharmaceutical, MA) in patients with relapsed or refractory WM. METHODS: Patients who had at least one previous therapy for WM, and who had symptomatic relapsed or refractory disease were eligible. NCI CTCAE v3.0 was used for toxicity assessment. All patients received daily RAD001 at 10 mg. A cycle was considered 28 days. Patients were allowed to stay on therapy until progression of disease or excessive toxicity. This study was conducted in a collaborative effort between Dana Farber Cancer Institute (DFCI) and Mayo Clinic College of Medicine. Here, we report the data on the patients accrued at DFCI. RESULTS: 19 pts (15 men and 4 women) have been treated to date. All patients had symptomatic disease and required therapy. The median number of lines of prior treatment was 3 (range 1 – 5) including included rituximab, nucleoside analogues (fludarabine or 2-CDA), combination chemotherapy (e.g. CHOP, CVP), chloramucil, and bortezomib. The median IgM at baseline was 3330 mg/dL (range 1010– 7410). The median follow on RAD001 was 8 months (range 3 – 22 months). Eighteen pts are currently evaluable for response. Best responses to RAD001 after 2 cycles using IgM monoclonal protein were as follows: partial remission in 8 (44%), minimal response in 5 (28%). Progressive disease occurred in 4 (22%) and stable disease occurred in 1 (6%). The overall response rate (PR+MR) was 72%. The median duration of response has not been reached (3–22+ months). Patients tolerated therapy well without significant toxicities. Grade 3 and 4 toxicities included grade 4 thrombocytopenia in 1 patient, grade 3 pneumonia in 1 patient, grade 3 hyperglycemia in 1 patient and grade 3 mucositis in 1 patient. Other adverse events of grade 2 or lower included nail cracking, mucositis, diarrhea, and fatigue. Attributable toxicities otherwise proved manageable with appropriate supportive care, and RAD001 was generally well tolerated. One patient enrolled on the study withdrew consent and changed to hospice care within 3 weeks of therapy, and passed away due to disease progression. CONCLUSIONS: The use of the oral RAD001 single agent RAD001 in patients with relapsed or refractory WM was welltolerated and demonstrated significant activity achieving an overall response rate in 72% of patients. Future studies of combination of this agent with rituximab and bortezomib are currently being planned.

Abstract Background: Pomalidomide-dexamethasone results in an overall response rate of 33% and median PFS of 4.2 months in patients with prior lenalidomide and bortezomib (Richardson et al. Blood 2014). In this randomized phase II trial, we compared pomalidomide-dexamethasone (arm B) versus the addition of oral weekly cyclophosphamide to pomalidomide-dexamethasone (arm C) in patients with lenalidomide-refractory multiple myeloma (MM). We have previously reported that the recommended phase II dose of cyclophosphamide with standard-dose pomalidomide + dexamethasone was 400 mg PO D1, 8, 15. Patients and Methods: Eligible patients had relapsed and refractory MM after at least 2 prior therapies and were lenalidomide refractory. Patients had a platelet count ≥ 50,000/mm3 and ANC ≥ 1,000/mm3 (patients with ≥50% bone marrow plasmacytosis were allowed if platelet count was ≥ 30,000/mm3and ANC could be supported with GCSF during screening and therapy). Patients were randomized (1:1) to receive pomalidomide 4 mg PO D1-21 and dexamethasone 40 mg PO D1, 8, 15, 22 (20 mg if older than 75 years) (arm B) with or without oral cyclophosphamide 400 mg PO D1, 8, 15 of a 28-day cycle (arm C). Patients randomized to arm B were allowed to cross over to arm C in the event of disease progression. Thromboprophylaxis was mandated with aspirin, warfarin, or LMWH. The primary endpoint was overall response rate using IMWG criteria. Secondary endpoints included an evaluation of PFS, OS and safety of the two arms. Results: Between 7/2012 and 3/2014, 36 patients were randomized to arm B and 34 to arm C. Patients characteristics were not different between the 2 arms (table below). The median number of prior therapies was 4 (2-12). All patients were lenalidomide refractory and none received prior pomalidomide. After a median follow up of 15 months, the overall response rate (partial response or better) was 39% and 65% (p=0.03) for arm B and C, respectively. The clinical benefit rate (minimal response or better) was 64% and 79% (p=0.2) for arm B and C, respectively. The median PFS was 4.4 months (95% CI 2.3-5.9) for arm B and 9.2 months (95% CI 4.6-16) for arm C (log rank p=0.04). As of July 2014, 28 patients had died (16 arm B, 12 arm C) with median overall survival of 10.5 versus 16.4 months (p=0.08) for arm B and C, respectively. Hematologic grade 3/4 adverse events were more frequent in arm C, although this was not statistically significant (see table). Thirteen patients crossed over and oral weekly cyclophosphamide was added to their tolerated dose of pomalidomide dexamethasone. For those patients, the best response was as follows: 2 PR, 2 MR, and 6 SD, 3 PD. Conclusions: Pomalidomide-dexamethasone in combination with oral weekly cyclophosphamide resulted in a superior response rate and PFS compared to pomalidomide-dexamethasone alone in patients with relapsed and refractory MM. The increased hematologic toxicities, as a result of the addition of oral cyclophosphamide, were manageable.

2053 Background: Glioblastoma (GBM) is the most aggressive malignancy of the central nervous system. The majority have genetic changes that increase the activity of the phosphatidylinositol-3-OH kinase (PI3K) signal transduction pathway, critical for cell motility, proliferation, and survival. We present the results of PX-866, an oral PI3K inhibitor, in patients (pts) with recurrent GBM. Methods: A multinomial design of response and early progression (< 8 weeks on study) was used. In stage 1 (15 pts), 0 responses and ≥ 10 early progressions would stop accrual; after full accrual, ≥ 4 responses OR ≤ 13 early progressions was prespecified as of interest. Pts with histologically confirmed GBM, at first recurrence after chemoradiation and adjuvant temozolomide were given PX-866 8 mg daily on this single-arm phase II study. MRI and clinical exam were done every cycle (8 weeks). Tumour tissue was collected for analysis of potential markers of PI3K inhibitory activity (PTEN, EGFRviii, PIK3CA mutations). Results: A total of 33 pts were enrolled, eligible and evaluable. Median age was 56 (range 35-78), 12 were female; 29 had performance status (PS) 0-1 and 4 had PS 2. Median time from initial diagnosis to enrolment was 308 days (range 141-1256). Median number of cycles was 1 (range 1-7). Thirty-two pts have discontinued therapy, 26 due to disease/symptomatic progression and 6 due to toxicity (5 LFT elevation and 1 allergic reaction). Other adverse effects (AE): fatigue (16 pts/2 grade 3), diarrhea (11 pts/5 grade 3), nausea (19 pts/1 grade 3), vomiting (11 pts/1 grade 3) and lymphopenia (29 pts/7 grade 3/4). Five pts had related serious AEs (1 LFTs, 1 GI and 3 venous thromboembolism) All pts were evaluable for response; 25 had a best response of progression, 1 had partial response (overall response rate 3%) and seven (21%) had stable disease (SD, median 7.3 months; range 3.1-13.6). Six month PFS was 17%. In preliminary analyses, no statistical association was found between SD and PTEN or EGFRviii status (results pending in 16 pts). Conclusions: PX-866 was relatively well tolerated. Overall response rate was low, and the study did not meet its primary endpoint; however, 21% of pts obtained durable stable disease. Further correlative work is required to identify the predictor of this effect. Clinical trial information: NCT01259869.

15006 Background: The aim of this trial was to investigate the efficacy and toxicity of weekly combination of docetaxel (D) and gemcitabine (G) in the management of recurrent ovarian, peritoneal, or fallopian tube cancer. Methods: D (30 mg/m2) was given as a one-hour IV infusion followed by G (650 mg/m2) as a 30 minute IV infusion on Day 1, 8 & 15 of a 28-day cycle. Results: Thirty pts were enrolled. Mean age was 67.4 (range 47–85). Twelve (40%) pts had Platinum sensitive disease, and 18 (60%) had Platinum resistant disease. One hundred eighteen cycles were evaluable for toxicity. The mean number of cycles was 4 (range 1–7). Twenty-six (22%) of the cycles were incomplete due to toxicity (day # 15 not given in 25 of the incomplete cycles). Dose delay was observed in 4 (13.3%) pts, and a one-dose level reduction was required in 11 (36.7%) pts. Hematologic toxicity included grade 3 neutropenia in 13 (11%) cycles, grade 3 thrombocytopenia in 11 (9.3%) cycles. No grade 4 neutropenia, thrombocytopenia or neutropenic fever was encountered. Bone marrow support with erythropoiten (36.6% pts), and filgrastim (13.3% pts) were utilized. Blood transfusions were given in 10 (8.5%) cycles. Elevated LFT grade 1/2 was seen in 7 (23.3%) pts and 3 (10%) pts, respectively. Nonhematologic grade 3 toxicites occurred in 4 pts (including one seizure). Mean follow-up interval was 19.6 months (mos) (range 1–36.6). To date, 14 (46.6%) pts are alive with disease, and 16 (53.4%) have died of disease. The overall response rate was 32% (1 CR and 8 PR in 28 evaluable pts). Ten pts (33.3%) had SD and 5 had ID. Median progression-free interval (PFI) was 3.8 mos (95% CI: 1.65–5.97). Overall survival was 19.6 mos (95% CI: 14.23–24.96), and no significant differences in PFI and survival between the Platinum-sensitive and resistant pts (P = 0.5, P = 0.08, respectively). Conclusions: Weekly docetaxel plus gemcitabine is an active and tolerable regimen with minimal toxicity in this older population of pts (9 ≥ 80 years of age). No significant difference in response between Platinum sensitive and resistant pts was observed. Overall response rate appears to be better than single agent regimens currently available. Elimination of the third week of treatment may not affect efficacy and will be more acceptable to pts with less toxicity. No significant financial relationships to disclose.

e15592 Background: Based on promising published data, this multicenter, phase II study was initiated to investigate a combined treatment using DC and cetuximab in the first-line setting for patients with gastric cancer. Methods: Patients aged 18–75 years with stage III (T4, nonresectable) or stage IV gastric cancer, ECOG performance status (PS) ≤2, and life expectancy ≥3 months were recruited to receive cetuximab (400 mg/m2 on day 1 then 250 mg/m2 q1w) and DC (D 75 mg/m2 and C 75 mg/m2; both as 1-h infusions on day 1 and then q3w). Treatment was stopped in the event of disease progression, intolerable toxicity, or consent withdrawal. Tumor staging was performed after cycle 3 and then every 12 weeks. The primary endpoint was overall response rate and secondary endpoints included time to progression, overall survival and toxicity. Planned accrual was 79 patients. A per-protocol interim response analysis was planned for the initial 20 evaluable patients. Results: Preliminary data are available for 30 patients; median age 64 [range: 40–73] years; median ECOG PS 1 [range: 0–2]; adenocarcinoma 87%. Median cycles administered were 3 [range: 1–14] and the median follow-up was 1.63 months. The overall response rate was 27.3% (complete response, n=1; partial response, n=5). Stable disease was observed in 10 patients, and disease progression in 6 patients. The most relevant NCI-CTC grade 3–4 hematologic events per patient were leukopenia and neutropenia (73%), anemia (13%), and febrile neutropenia (10%). Major grade 3–4 nonhematologic toxicities were nausea (30%), vomiting (20%), diarrhea (13%), acne (13%), and fatigue (13%). Conclusions: DC and cetuximab were well tolerated and resulted in promising response rates and a predictable toxicity profile. The study is ongoing.

Abstract Accelerated phase marks the onset of advanced rapidly progressive chronic myelogenous leukaemia (CML) and generally leads finally to a fatal blast crisis (BC) within 6 months. Gleevec (imatinib mesylate) as a potent tyrosine kinase inhibitor has demonstrated significant activity in chronic phase (CP) of CML. Because of the observed activity and favorable tolerability of Gleevec and because of the limited treatment options available to these patients we have introduced Gleevec in CML patients meeting rigorous criteria for acceleration and blast crisis phase of CML. PATIENTS: MALE - 31 and FEMALE - 20 were eligible for inclusion in this study if they were at least 18 years old and had a diagnosis of Ph+ CML (AP; BC) confirmed by cytology, histology, cytogenetic and molecular analyses.

Introduction: Fludarabine treatment has been shown to be beneficial for patients with Chronic Lymphocytic Leukemia (CLL), and fludarabine-based combinations may even further improve outcomes in patients with CLL. However, most CLL patients eventually become fludarabine refractory, a state which is associated with a relatively short survival. Treatment of fludarabine-refractory patients is challenging, with a median survival of about 10 months. Recently, 2 phase II clinical trials (Chanan-Khan et al. JCO 2006 and Ferrajoli et al. ASH 2006) demonstrated the clinical efficacy of lenalidomide, an immunomodulatory agent, in relapsed/refractory CLL patients. We conducted a subset analysis to examine the efficacy of lenalidomide in patients who are fludarabine refractory. Methods: All patients enrolled on the 2 phase II single agent lenalidomide clinical trials were evaluated and patients with fludarabine-refractory disease (progressed while on or within 6 months of fludarabine-based therapy) were assessed for clinical efficacy of lenalidomide. Lenalidomide was given orally either at 10 mg daily for 28 days followed by 5 mg increments every 28 days to a maximum dose of 25 mg or given at 25 mg on days 1–21 of each 28-day cycle. Response was assessed using the NCI-WG 1996 criteria. Results: A total of 80 patients were collectively enrolled in these clinical studies. Among these, 29 were identified to have fludarabine-refractory disease. Important clinical characteristics of these patients are reported in Table 1. The overall response rate in fludarabine-refractory patients was 34.5% (10/29). Complete remission was observed in 2 (6.8%) patients. Conclusion: Lenalidomide is a novel agent with immunomodulating properties demonstrating clinical efficacy in relapsed or refractory CLL patients. Interestingly, clinical responses to single agent lenalidomide were noted despite refractoriness to fludarabine (a subset of CLL patients with poor survival and limited therapeutic options). This observation of the clinical benefit of lenalidomide independent of responsiveness to prior fludarabine is encouraging and warrants further evaluation. Table 1 Ferrajoli et al. Chanan-Khan et al.

Abstract Abstract 1634FN2 Introduction: The treatment of patients with DLBCL who are unsuitable for anthracycline containing chemotherapy remains a clinical challenge. Gemcitabine is a nucleoside analogue which has proven efficacy in the relapse setting in both non Hodgkin's and Hodgkin's lymphoma. We therefore developed a protocol incorporating Gemcitabine in a first line approach combined with CVP-R chemo-immunotherapy in DLBCL patients considered unfit for anthracycline containing chemotherapy. Methods: We performed a prospective, multicentre phase II trial in patients with DLCBL who were considered unfit for anthracycline containing chemo-immunotherapy. Eligibility criteria included ejection fraction < 50%, or ejection fraction ≥ 50% but with the presence of attendant significant co-morbidities (including: ischaemic heart disease, hypertension, diabetes mellitus), and ECOG PS 0–3. Patients received 6 cycles of Rituximab (375 mg/m2 IV D1), Cyclophosphamide (750mg/m2 IV D1), Vincristine (1.4 mg /m2 IV D1), Prednisolone (100mg, orally D1–5) and Gemcitabine IV D1 and D8. The Gemcitabine dose, if tolerated was sequentially escalated from 750mg/m2 in cycle 1 to 875mg/m2 in cycle 2 to 1000mg/m2 in cycle 3 with the dose maintained at 1000mg/m2 for cycles 4–6. Cycles were repeated every 21 days with growth factor support administered on day 9 of each cycle (pegfilgrastrim 6mg s/c).The primary endpoint was to achieve an overall response rate of > 40% assessed by CT scan at the end of treatment according to the Cheson criteria. Secondary endpoints were progression free survival and overall survival. Results: 62 patients were recruited from 32 UK sites over a 28 month period from April 2008 to July 2010. 66% were male. Median age was 76 years (range 52–90), 48 (77%) were > 70 years. 43 (69%) had stage III/IV disease and 46 (72%) had high – intermediate or high IPI (3–5) disease. ECOG performance status was ≥ 2 in 50% patients. Left ventricular ejection fraction (LVEF) was < 50% in 28 patients (45%). The 34 patients with LVEF ≥ 50% had significant co-morbidities, 22 (65%) had multiple co-morbidities. 44 (70%) received ≥ 3 cycles of treatment, reasons for early termination of treatment in the remaining 18 patients were progression (n=2), toxicity (n=5), death (n=6) patient choice (n=1) and other (n=4). 29 patients (47%) received the full 6 cycles. A total of 250 treatment cycles were delivered. Of the 44 patients who received ≥ 3 cycles of treatment, the dose of Gemcitabine was escalated to the full dose (1000mg/m2) in 67%. Day 8 Gemcitabine was delivered in 215/250 (86%) cycles of treatment. The overall response rate (CR/CRu/PR) at end of treatment for all 62 patients was 60%. For patients who received ≥ 3 cycles of treatment (n =44) the ORR was 79.5% at the end of treatment. There was no significant difference in ORR between those with LVEF <50% and those with LVEF ≥ 50% (71% vs 53%, p=0.155). At a median follow up of 18.2 months the 1 year progression free survival rate for all patients was 52.9% (95% CI 39.4–64.8). The 1 year overall survival (OS) rate is 62.4% (95% CI 48.5–73.6). For the group with LVEF <50% OS was 70.8% (95% CI: 48.4, 84.9) and LVEF group ≥ 50% OS was 55.9% (95% CI 37.1–71).Grade 3/4 haematological toxicity was observed in 54.1% patients. Grade 3/4 infection was observed in 24.6% of patients. The death rate observed related to infection for the whole cohort was 11%. Conclusion: This multicentre trial demonstrates that the R-GCVP regimen delivers excellent overall response rates with durable remissions in a group of patients where anthracycline use was precluded. The efficacy attained in this difficult group of patients provides a platform for testing the regimen in subsequent randomised phase II and phase III studies to confirm its efficacy.
