Abstract Abstract 5141 Incorporation of bortezomib in the treatment of multiple myeloma (MM) has significantly imporved patient outcome. Because peripheral neuropathy (PN) leading to dose modification and drug discontinuation seems to be dependent on dose and exposure of bortezomib, some schedules of botezomib therapy were reduced from twice-weekly to once-weekly infusion. We assessed the efficacy and safety of once-weekly bortezomib infusion in the treatment of relapsed/refractory MM. We compared the outcomes and safety of once- and twice-weekly bortezomib infusion as a second-line treatment for the patients of relapsed/refractory MM in our hospital between 2005 and 2010, retrospectively. Twenty-nine patients were enrolled including 12 patients who received once-weekly bortezomib infusion on day 1, 8, 15 and 22 of the cycles and 19 patients who received twice-weekly bortezomib infusion on day 1, 4, 8 and 11 of the cycles as a second-line treatment. Dexamethasone alone (n=18), melpahalan with prednisolone (n=4), and thalidomide with dexamethasone (n=7) were administered combined with bortezomib. Median cumulative dose of bortezomib were 32.4mg/m2 and 18.4mg/m2 in the once- and twice-weekly group, retrospectively (p=0.019). There were no significant difference in overall response rate (66.7% in once-weekly vs 47.1% in twice-weekly, p=0.451) and time-to-progression (median 17.2 months in once-weekly vs 7.1 months in twice-weekly, p=0.381). There was a significant difference in the median time-to-onset of grade 2 to 4 PN (4.5 months in once-weekly vs 2.0 months in twice-weekly, p=0.017). The incidence of grade 2–4 PN (50.0% vs 47.1%) and median cumulative dose to onset of grade 2–4 PN (17.9mg/m2 vs 15.3mg/m2) were not different. The incidence of any grade 3/4 toxicity except PN was similar (25.0% vs 41.2%, p=0.449). Progression-free survival in once-weekly bortezomib group was slightly longer than that in twice-weekly bortezomib (median 34.8 months vs median 22.8 months, p=0.074). Overall survival was similar (median 35.2 months vs median 25.1 months, p=0.118), while the overall survival of elderly patients (60 years or above) in once-weekly bortezomib group was slightly longer than that in twice-weekly bortezomib group by Kaplan-Meier analysis (median 38.1 months vs median 20.1 months, p=0.085). Our data suggest that the onset time of PN was delayed in once-weekly regimen and there was no significant difference overall response, rate of PN, cumulative dose to onset of PN, grade 3/4 toxicity and overall survival between both groups. Because of the larger cumulative dose and the lower rate of dose modification or drug discontinuation due to good tolerability in once-weekly bortezomib than twice-weekly bortezomib, once-weekly bortezomib infusion could be a potential therapeutic approach for patient with MM as a scond-line therapy.

PURPOSE Melphalan flufenamide (melflufen) is a first-in-class peptide-drug conjugate that targets aminopeptidases and rapidly and selectively releases alkylating agents into tumor cells. The phase II HORIZON trial evaluated the efficacy of melflufen plus dexamethasone in relapsed and refractory multiple myeloma (RRMM), a population with an important unmet medical need. PATIENTS AND METHODS Patients with RRMM refractory to pomalidomide and/or an anti-CD38 monoclonal antibody received melflufen 40 mg intravenously on day 1 of each 28-day cycle plus once weekly oral dexamethasone at a dose of 40 mg (20 mg in patients older than 75 years). The primary end point was overall response rate (partial response or better) assessed by the investigator and confirmed by independent review. Secondary end points included duration of response, progression-free survival, overall survival, and safety. The primary analysis is complete with long-term follow-up ongoing. RESULTS Of 157 patients (median age 65 years; median five prior lines of therapy) enrolled and treated, 119 patients (76%) had triple-class–refractory disease, 55 (35%) had extramedullary disease, and 92 (59%) were refractory to previous alkylator therapy. The overall response rate was 29% in the all-treated population, with 26% in the triple-class–refractory population. In the all-treated population, median duration of response was 5.5 months, median progression-free survival was 4.2 months, and median overall survival was 11.6 months at a median follow-up of 14 months. Grade ≥ 3 treatment-emergent adverse events occurred in 96% of patients, most commonly neutropenia (79%), thrombocytopenia (76%), and anemia (43%). Pneumonia (10%) was the most common grade 3/4 nonhematologic event. Thrombocytopenia and bleeding (both grade 3/4 but fully reversible) occurred concomitantly in four patients. GI events, reported in 97 patients (62%), were predominantly grade 1/2 (93%); none were grade 4. CONCLUSION Melflufen plus dexamethasone showed clinically meaningful efficacy and a manageable safety profile in patients with heavily pretreated RRMM, including those with triple-class–refractory and extramedullary disease.

e15016 Background: Although regorafenib and fruquintinib have been recommended as the third-line treatment for patients with refractory metastatic colorectal cancer (mCRC), the median survival time of mCRC is still only for 4-8 months and the low response rate and unpleasant side effects limit their use in Chinese patients. Apatinib, an oral VEGFR-2 inhibitor, has been approved as a third line treatment in metastatic gastric cancer. In addition, apatinib has demonstrated good safety, tolerability, and efficacy in the treatment of advanced solid tumors. The aim of this study was to assess the efficacy and safety of apatinib combined with S-1 in the treatment of refractory mCRC. Methods: In this prospective, open-label, single-arm, multicenter, phase II study, patients after failure of second-line chemotherapy were enrolled and took apatinib (250mg, daily) combined with S-1 (standard dose). The primary endpoint was progression free survival (PFS) and the second endpoint was response rate and overall survival time. Results: From December 2017, 22 patients (14 male) with a median age of 56y (range: 34-71 y) were enrolled and eligible for evaluation of the PFS, response rate and safety. The median PFS was 105d (95% CI: 79.01-130.98). two patients (9%) achieved partial response, 15 (68.18%) achieved stable disease, and 5 (22.72%) were progressive disease. The objective response rate and the disease control rate were 9% and 77.27%, respectively. Median overall survival was not reached. The common adverse effects were abnormal liver function (7/22; 31.81%), leukopenia (5/22; 22.72%) and thrombocytopenia (4/22; 18.18%). The incidence for grade 3-4 side effect was very low. One patient experienced grade 3 proteinuria and there were no toxic deaths. Conclusions: This preliminary result indicated that apatinib combined with S-1 may extend the PFS in mCRC, with well-tolerated toxicities, making it a promising therapeutic target for mCRC treatment.

Abstract Background: Severe thrombocytopenia is an uncommon event in patients (pts) with lower-risk MDS, but it may significantly affect the prognosis. No specific pharmacological approaches other than hypometilating agents (not licensed in Europe in lower-risk MDS), able to improve platelet count in this setting, are currently available. Trials testing efficacy and safety of Eltrombopag are ongoing (Oliva 2017). Few data were reported about danazol, an attenuated androgen, that seems to have also some effectiveness in this still unmet need (Wattel 1994; Chan 2002). Aims: To assess the efficacy and safety of danazol in improving the platelet count in low risk MDS pts with severe thrombocytopenia. Methods: We retrospectively reviewed 35 thrombocytopenic MDS pts treated with danazol. The initial and maximal dose was 600 mg/day for all pts, modulated according to response and toxicity. The response was evaluated according to IWG response criteria (Cheson 2006). The outcome was strictly observed every 3 months (mo) up to the 12th mo, and the platelets average number in each observation moment was described. The time to response, the response rate and the enduring of response were also recorded. Results: Of the 35 pts, according to 2016 WHO classification, 4 pts were MDS-ULD; 19 were MDS-MLD (3 of them with medullar hypocellularity), 7 were MDS-EB1 and 5 were affected by MDS/MPN. At baseline the platelet count was lower than 20x10^3/mL in 11 pts, the median was 23x10^3/mL . At starting time of danazol therapy the IPSS-R cytogenetic class of risk was very low in 2 cases, low in 28 cases, intermediate in 3 cases and very high in 1 case. Cytogenetic was not available in one patient. In the 30 MDS pts, the IPSS-R was "very low" in 1 patient, "low" in 16, "intermediate" in 7, "high" in 4 and "very high" in 1. In 1 case it was not evaluable due to the lack of cytogenetics. Two pts were not included in the analysis because they were treated for less than 3 mo (in 1 case danazol was withdraw to permit the beginning of another therapy and in 1 case due to death for other neoplastic disease). The response rate was 63,6% (21 responders on 33 evaluable). Median time to response was 3.5 mo (range 0.3 - 12.4 mo); the average response time was 5.09 mo. In the first year of treatment, the platelet count (evaluated at baseline, 3, 6, 9 and 12 mo) changed in a significant way (F test after repeated measures ANOVA: p < 0.001 as shown in Figure 1). Pairwise comparisons of platelet count according to Bonferroni showed a significant difference for baseline vs. 3 mo (p = 0.0013), baseline vs 6 mo (p = 0.0255), baseline vs 9 mo (p = 0.0047) and baseline vs 12 mo (p = 0.0014); however, no significant differences (p ≥ 0.05) in counts were seen for all the further pairwise comparisons at 3, 6, 9 and 12 mo. The median and average duration of the response for the entire population were respectively 12,5 and 32,5 mo. Only 6 of the 21 responders (28%) lost the response (the median and average duration of response were respectively 5.8 and 12.9 mo). Within the 21 responders, the median progression free survival was not reached after 24 mo. The probability to maintain the response after 50 mo was assessed at 58.2% (C.I. 24.1% to 81.4% - Figure 2). The overall survival showed a significant difference (logrank test: p = 0.0064) between responders and non-responders (Figure 3). Adverse events recorded were as follows: moderate (grade 1 and 2) increase in transaminases in 4 cases (with reduction of danazol to 400 mg/day); 1 case of severe but reversible liver toxicity (grade 3) (with subsequently drug suspension); severe (grade 3) but reversible renal failure in 1 case (the drug was stopped); moderate (grade 1 and 2) increasing of serum creatinine in 6 case (with reduction of danazol to 400 mg/day in 2 of these); reversible cutaneous rash in 3 cases; amenorrhea in 1 case (the only fertile woman in the series); weight loss and loss of appetite in 1 case, weight gain in 1 case. Conclusion: Even if the mechanism of action of danazol in pts with MDS is unclear, this series confirms its efficacy to improve platelet count in the most of MDS pts with severe thrombocytopenia. The response was often clinically significant. It may not be immediate but seems to be reachable after 3-6 mo of treatment. A responsive patient has a good probability to maintain a long-lasting response. The toxicity profile of this drug is acceptable. Waiting for more effective options, danazol may be a good therapeutic option for these pts. Disclosures Riva: Jannsen and Cilag: Consultancy; Novartis: Consultancy; Celgene: Consultancy.

Aim: We performed an updated meta-analysis to evaluate the efficacy and safety of lenvatinib in cancer patients. Materials & methods: Databases were searched to identify relevant trials. Data were extracted to evaluate overall survival, progression-free survival, overall response rate and grade ≥3 adverse events. Results: The pooled analysis demonstrated that lenvatinib significantly improved progression-free survival (hazard ratio: 0.43; 95% CI: 0.23–0.80; p = 0.008), overall survival (hazard ratio: 0.85; 95% CI: 0.75–0.97; p = 0.013) and overall response rate (relative risk: 6.89; 95% CI: 2.22–21.36; p = 0.001) compared with control therapy. However, the use of lenvatinib can increase the risk of severe infection. Conclusion: Lenvatinib-containing regimens are associated with better progression-free survival, overall survival and overall response rate, but can induce severe infection.

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.

5049 Background: In a phase 3, randomized, 3-arm study of TEMSR or IFN or the combination of TEMSR + IFN in the first-line treatment of patients with advanced renal cell carcinoma (RCC) and poor-prognostic features, TEMSR improved overall survival (p=0.0069) and progression-free survival (p=0.0001) vs. IFN (Hudes et al. J Clin Oncol. 2006;24:LBA4). Quality-adjusted survival was a pre-defined endpoint and is reported. Methods: Quality-adjusted time without symptoms and toxicity (QTWiST) was estimated by partitioning overall survival into 3 distinct health states: time with serious toxicity, time with progression, and time without symptoms and toxicity (TWiST). Survival was value-weighted when patients completed quality of life questionnaires (EQ-5D) at weeks 12 and 32, when a grade 3 or 4 adverse event (AE) was reported, upon relapse or progression, or upon withdrawal from the study. Treatment group comparisons used restricted means analyses estimated from censored survival data. Restricted means were computed for duration of each health state by truncating data at median follow-up (17.9 months). Variance and covariance were estimated using bootstrap methods. Results: All 626 randomized patients in the study were included in computation of health state durations. EQ-5D questionnaires were obtained from 260/300 (87%) upon progression and 230/570 (40%) after a grade 3/4 AE. Patients receiving TEMSR alone had 38% greater TWiST than those receiving IFN alone (TEMSR=6.5 months vs. IFN=4.7 months, p=0.00048). There was no significant difference in TWiST between the combination arm and IFN alone (IFN+TEMSR=5.4 months vs. IFN=4.7 months, p=0.1288). Patients receiving TEMSR alone had 23% greater Q-TWiST than those receiving IFN alone (TEMSR=7.0 months vs. IFN=5.7 months; p=0.0015). There was no significant difference in Q-TWiST for the combination arm compared with IFN alone (IFN+TEMSR=6.1 months vs. IFN=5.7 months, p=0.3469). Conclusions: Patients with advanced RCC receiving TEMSR alone had significantly greater quality-adjusted survival than those receiving IFN alone. No significant financial relationships to disclose.

Summary Purpose Apatinib, a new tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor-2, has shown promising efficacy against several solid cancers, but evidence of its efficacy against relapsed and refractory nasopharyngeal carcinoma is limited. We investigated the efficacy and safety of apatinib for relapsed and refractory nasopharyngeal carcinoma in an open-label, single-arm, phase II clinical trial. Fifty-one patients with relapsed and refractory nasopharyngeal carcinoma in the First Affiliated Hospital, Zhengzhou University, who met the inclusion criteria were enrolled in the study. All patients received apatinib at an initial dose of 500 mg daily (1 cycle = 28 days). The primary and secondary endpoints were overall response rate, progression-free survival, and overall survival. We evaluated treatment effects and recorded apatinib-related adverse events by performing regular follow-ups and workup. The overall response rate (complete and partial responses) was 31.37% (16/51). The median overall survival and progression-free survival were 16 (95% CI, 9.32–22.68) and 9 months (95% CI, 5.24–12.76), respectively. Most patients tolerated treatment-related adverse events of grades 1 and 2; hypertension (29, 56.86%), proteinuria (25, 49.02%), and hand–foot syndrome (27, 52.94%) were the most common adverse events. There were no treatment-related deaths. Apatinib showed good efficacy and safety in patients with relapsed and refractory NPC.

Purpose This multicenter, open-label, phase II study evaluated the combination of bendamustine, gemcitabine, and vinorelbine (BeGEV) as induction therapy before autologous stem-cell transplantation (ASCT) in patients with relapsed or refractory Hodgkin lymphoma (HL). Patients and Methods Patients with HL who were refractory to or had relapsed after one previous chemotherapy line were eligible. The primary end point was complete response (CR) rate after four cycles of therapy. Secondary end points were: overall response rate, stem-cell mobilization activity, and toxicity. Progression-free and overall survival were also evaluated. Results In total, 59 patients were enrolled. After four cycles of therapy, 43 patients (73%) achieved CR, and six (10%) achieved partial response, for an overall response rate of 83%. The most common grade 3 to 4 nonhematologic toxicities included febrile neutropenia (n = 7) and infection (n = 4). Regarding hematologic toxicities, grade 3 to 4 thrombocytopenia and neutropenia were each experienced by eight patients (13.5%). CD34+ cells were successfully harvested in 55 of 57 evaluable patients, and 43 of 49 responding patients underwent ASCT. With a median follow-up of 29 months, the 2-year progression-free and overall survival rates for the total population were 62.2% and 77.6%, respectively. The same figures for patients undergoing autograft were 80.8% and 89.3%, respectively. Conclusion This phase II study demonstrates that BeGEV is an effective salvage regimen able to induce CR in a high proportion of patients with relapsed or refractory HL before ASCT. These data provide a strong rationale for further development of the BeGEV regimen.

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.

7059 Background: The combination of paclitaxel and carboplatin has been found to be effective in lung cancer and well tolerated. Method: This is a phase III randomized trial of paclitaxel and carboplatin (PC) versus vincristine, doxorubicin and cyclophosphamide (CAV) chemotherapy in limited or extensive stage disease patients but with a prognostic score in the intermediate or poor prognosis range.The aim of the study is to determine the one year survival rate, the objective response rate and toxicity. Patients were randomized to: four cycles of PC (paclitaxel 200mg/m2 by IV 3 hour infusion), followed by carboplatin (AUC of 6) by IV injection, 3-weekly or four cycles of CAV (cyclophosphamide 750mg/ m2, doxorubicin 40mg/ m2, vincristine 1.3mg/ m2 by IV injection) every 3-weeks. Thoracic radiotherapy was considered for appropriate patients. Results: 219 patients (110 for CAV and 109 for PC) patients were randomized. Pre-treatment characteristics were well balanced for stage, performance status, and age. There was significantly more grade 3/4 neutropenia in the CAV arm than the PC arm, 67% vs 38% (p < 0.005), whereas the PC arm, had more grade 3/4 thrombocytopenia (19% versus 8% p = 0.012). The PC arm had more grade 2 and 3 neuropathy. 56% grade 3 and 4 infections were observed on CAV arm and 35% on the PC arm (p < 0.005). Hospitalization required for severe neutropenia and infections was less with PC, compared to CAV (146 days for IV antibiotics compared to 308 days for CAV, p < 0.005). Response rates for CAV and PC were 59% and 61% respectively. One-year survival rates for the CAV arm was 6% and 13% for the PC arm. The intention to treat analysis concluded that there is statistical difference on the overall survival time in favor of PC (P = 0.014). Median survival was 94 days (CAV) and 154 (PC). Conclusions: CAV chemotherapy in SCLC patients is associated with higher risk of neutropenic sepsis than taxane based PC chemotherapy with no significant difference on the response rate. The overall survival was better for the PC arm. Final results will follow. No significant financial relationships to disclose.
