46 Background: We previously reported results of a randomized study showing that CX is equally active to ECX in terms of progression-free survival (PFS) (Yun et al. Eur J Cancer. 2010). Here we report updated overall survival (OS) results with an additional 12 months' follow-up. Methods: Ninety-one chemotherapy-naïve patients with histologically-confirmed, measurable AGC were randomized to receive CX (cisplatin 75 mg/m2 iv on day 1 and capecitabine 1,000 mg/m2 bid po on days 1-14, n=45) or ECX (epirubicin 50 mg/m2 plus CX, n=44) every 3 weeks. After CX or ECX had failed, second-line chemotherapy (SLC) was recommended for all patients if their performance status was preserved. Results: Treatment duration was similar for both arms (4.4 for CX v 4.2 months for ECX). There was no relevant difference in the occurrence of overall grade 3 or 4 toxicities between the CX and ECX arms (80% v 78%, respectively; p=0.516). However, none in the CX and 12% in the ECX arm discontinued treatment because of toxicity. There were no significant differences in therapeutic efficacy between CX and ECX with respect to the response rate (38% v 37%, respectively), PFS (6.4 v 6.5 months), as well as OS (12.7 v 13.8 months; p=0.51). After failure, 60% of patients (26 CX and 28 ECX patients) received SLC. However, OS was not differed whether a patient was treated with SLC or not (13.1 v 11.2 months; p=0.94). Conclusions: The present analysis confirms previous findings that both CX and ECX appear to be comparatively active as first-line chemotherapy for AGC. Furthermore, the role of SLC in AGC warrants further evaluation. No significant financial relationships to disclose.

Abstract BACKGROUND TMZ offers minimal benefit in pts with de novo uMGMT GBM. V is synergistic with RT and TMZ in uMGMT preclinical GBM models, safe when combined with either RT or TMZ clinically, but the triplet (V+RT+TMZ) is poorly tolerated. VERTU tested V in pts with uMGMT GBM. METHODS VERTU is a randomized Phase 2 trial comparing Standard Arm (Arm A), RT (60Gy/30 fractions) + TMZ (75mg/m2 daily) followed by TMZ (150–200mg/m2D 1–5) every 28 days for 6 cycles vs Experimental Arm (Arm B), RT (60Gy/30 fractions) + V (200mg PO BID) followed by TMZ (150–200mg/m2D 1–5) + V (40mg bid, D 1–7) every 28 days for 6 cycles in pts with de novo uMGMT GBM according to centralised testing. RESULTS 125 pts were randomized 1:2 (41:84). The 2 groups were matched for age, sex, performance status and extent of resection. Median follow-up was 25.8 months and 91 pts had died. The 6-month Progression-Free Survival (6mPFS) for Arms A and B were 34% (95% CI 20–48) and 46% (95% CI 36–57) respectively. The median PFS for Arms A and B were 4.2m (95% CI 2.5–6.0) and 5.7m (95% CI 4.1–6.6) respectively (HR = 0.80, 95%CI 0.55–1.18). 55% of pts in both arms experienced Grade 3/4 adverse events (AEs) with no significant differences in frequency or severity between the arms. Most common Grade 3/4 AEs were thrombocytopenia, seizures, hyperglycaemia and diarrhoea. CONCLUSION VERTU demonstrated that a novel treatment strategy for patients with de novo uMGMT GBM was feasible and tolerable. The observed 6mPFS and PFS were similar in both arms. Overall survival and other endpoints will be presented. Central MRI review, biomarker analyses, including DNA repair and methylation signature analyses are ongoing. (ANZCTR#ACTRN12615000407594).

8035 Background: NGR-hTNF, a selective antivascular agent, induces at low dose an initial vascular normalization that greatly enhances the intratumoral chemotherapy uptake, with synergistic effects that were noted especially in combination with cisplatin and gemcitabine. Methods: Chemo-naive patients (pts) with advanced NSCLC were stratified by histology (nonsquamous or squamous) and PS (0 or 1) and randomly assigned to receive cisplatin 80 mg/m2/d1 plus either pemetrexed 500 mg/m2/d1 (nonsquamous) or gemcitabine 1,250 mg/m2/d1+8 (squamous) every 3 weeks (q3w) for 6 cycles, with (arm A) or without (arm B) NGR-hTNF given at 0.8 μg/m2/d1/q3w until progression. Progression-free survival (PFS) was primary aim (1-β=80%, 1-sided α=10%, n=102). Secondary aims comprised adverse events (AEs), response rate (RR), and overall survival (OS). Results: Baseline characteristics in arm A (n=62) vs B (n=59) were: median age: 62 vs 63 years; men: 37 vs 39; PS 1: 23 vs 23; squamous: 18 v 17; smokers: 41 vs 43. For the nonsquamous stratum, 299 cycles were given in arm A (mean 7.0; range 1-20) and 192 in arm B (4.8; 1-6), while for the squamous stratum, 113 in arm A (6.7; 1-31) and 52 in arm B (3.5; 1-6). Rates of grade 3/4 AEs were similar (arm A vs B): neutropenia 13% vs 18%, anaemia 7% vs 4% and fatigue 7% vs 11%. No grade 3/4 AEs related to NGR-hTNF or bleeding/pulmonary hemorrhage events were reported in the squamous subset. With median follow-up time of 24.2 months, median PFS (5.8 vs 5.6 months; HR=0.92), RR (25% vs 21%) and 1-year OS (53% vs 53%) were similar between the two treatment arms. However, by predefined analysis in the squamous stratum, median PFS was 5.6 months for arm A and 4.3 months for arm B (hazard ratio, HR=0.75) and median OS was 14.2 months for arm A and 9.7 months for arm B (HR=0.49; p=0.07). In pts with squamous histology, RR was 38% for arm A and 27% for arm B (odds ratio=1.6), while the median changes in tumor size on treatment from baseline to 2nd, 4th and 6th cycle for arm A vs B were -32% vs -20%, -41% vs -19%, and -42% vs -14%, respectively. Conclusions: Clinical tolerability and benefit were noted in squamous NSCLC with NGR-hTNF plus cisplatin and gemcitabine, which deserve further investigation.

5059 Background: NGR-hTNF (asparagine-glycine-arginine human tumor necrosis factor) is able to promote antitumor immune responses and to improve the intratumoral doxorubicin (D) uptake by selectively damaging tumor vessels. Methods: OC patients (pts) with progressive disease (PD) after ≥ 1 platinum/taxane regimen and with a platinum free interval lower than 6 months (PFI <6) or ranging from 6 to 12 months (PFI 6-12) received NGR-hTNF (N) 0.8 µg/m2 and D 60 mg/m2 on day 1 every 3 weeks. Primary endpoint of this phase 2 trial was response rate by RECIST criteria with a target of ≥ 6/37 responding pts. Secondary aims were progression free survival (PFS) and overall survival (OS). Results: 37 pts (median age 57 years; PS 0/1 32/5; PFI < 6/6-12 25/12; prior regimens 1-5) were enrolled. Median baseline peripheral blood lymphocyte count (PBLC) was 1.6/mL (interquartile range 1.2-2.1). In all, 177 cycles were given, with 18 pts (49%) receiving ≥ 6 cycles and 12 pts (32%) 8 cycles. Neither grade 3/4 adverse events (AEs) related to N nor increase of D-related AEs were noted. Common grade 1/2 AEs included chills (65%). Eight pts (23%; 95% CI 12-39) had partial response (PR; 2 with PFI < 6 and 6 with PFI 6-12; median duration: 8.2 months). Fifteen pts had stable disease (SD, 43%; 10 with PFI < 6 and 5 with PFI 6-12; median duration: 4.9 months) for an overall disease control (DC, PR+SD) rate of 66%. Mean changes from baseline in target tumor size after 2, 4, 6, and 8 cycles were 2%, -54%, -69%, and -77%, respectively. Median PFS was 5.0 months (95% CI 3.1-6.9) and median OS was 17.0 months (10.4-23.6). In pts with PFI < 6 or 6-12, median PFS were 3.8 and 7.8 months (p=.03) and median OS were 14.3 and 20.1 months (p=.14), respectively. Pts with DC had longer median OS than those with early PD (24.0 and 4.9 months, respectively, p=.02). Longer PFI (p=.03) and higher PBLC (p=.01) were associated with better PFS, while OS correlated only with PBLC (p=.001). In the subset with PFI < 6, pts with PBLC ≥ or < 1.2/mL (1st quartile) had median PFS of 4.9 and 2.6 months (p=.02) and median OS of 15.8 and 4.3 months (p=.0001), respectivel Conclusions: A randomized phase II trial is currently testing D ± NGR-hTNF in pts with PFI < 6 (refractory/resistant). The role of PBLC as blood-based biomarker deserves further investigation.

145 Background: ACRPC causes >30,000 deaths/year in the USA. The front-line treatment consists of docetaxel-based chemotherapy (D). 50% of patients (pts) show at least a 50% PSA decline during D and >15% show a partial response (R) in measurable disease. However, most of these pts present progression (P) after a median of 6-8 months (m). mCRPC remains driven by ligand-dependent androgen (A) receptor signaling. Ketoconazole (K) is a nonspecific cytochrome-P 17 inhibitor (CYP17i) able to block adrenal A synthesis. Low-dose K (LDK), (200 mg, t.d.s) has shown interesting activity in mCRPC after P to androgen deprivation therapy (ADT). The FDA recently granted approval to Abiraterone acetate, a selective CYP17i showing a survival benefit after P to D. The role of a CYP17i in the maintenance setting after response/stabilization to D has never been studied. Methods: 38 mCRPC pts starting D after P to ADT maintained LHRHa and additionally received a median of 7 cycles (3-12) of front-line three-weekly D (75 mg/m2) plus daily prednisone (10 mg). 20/38 pts showing no progression to D were enrolled. One month after the last D cycle 10 pts were assigned to MT with LDK plus prednisone (10 mg daily) and continued to receive LHRHa while the 10 pts in the control arm continued on LHRHa alone. Progression-free survival (PFS) was the primary endpoint of the study. Results: After a median follow-up of 27 m, all pts in the control arm progressed after D treatment while 8/10 pts progressed to MT. PFS from D initiation was 11.4 m for MT and 8.9 m for control arm (p=0.025). Toxicity profiles showed no significant differences between both arms. No pts discontinued LDK for toxicity reasons. Conclusions: To our knowledge, this is the first study testing a CYP17i for MT after response/stabilization to D in mCRPC. Although this is a small cohort of pts and a longer follow-up is needed, these preliminary data show a significant benefit in PFS of more than 2 months with LDK MT compared to no MT after D with a favorable toxicity profile. Thus, a further analysis in a larger series and the potential impact of this PFS benefit on the overall survival is warranted.

474 Background: Colorectal cancer (CRC) is the third most common cancer in the US. Half of pts diagnosed with CRC develop liver disease. Unresectable liver metastases are responsible for morbidity/mortality. Typically, pts with metastatic CRC receive an oxaliplatin- or irinotecan-based regimen as first-line chemotherapy, +/- bevacizumab. On progression, pts are treated with the regimen they did not receive during first-line chemo. A study to evaluate yttrium 90 glass microspheres (TheraSphere; 90Y) in pts with unresectable mCRC of the liver showed that pts with good performance status, no extrahepatic metastases, and ≤ 25% tumor may benefit most from 90Y. 90Y glass microspheres are approved by FDA under a Humanitarian Device Exemption (HDE). This study will evaluate outcomes in this patient subset when 90Y is added to second-line SOC chemo. The objective is to evaluate efficacy/safety of 90Y in patients with liver mCRC that has progressed after first-line chemo. Methods: Open-label, multi-center, randomized study to evaluate 90Y treatment in ~340 eligible pts, in whom SOC 2nd-line chemo with either an oxaliplatin or irinotecan-based regimen is planned. Eligible pts will be randomized 1:1 to control or treatment. Treatment pts will receive a first cycle of second-line chemo within 21 days of randomization and at least 14 days after the last dose of first-line agents including VEGF inhibitors. 90Y will be administered in place of the second chemotherapy cycle. Control pts will receive planned SOC second-line chemo. Primary endpoint is progression-free survival. Secondary: overall survival, hepatic progression-free survival, time to symptomatic progression, tumor response rate, and adverse events. Pts will have regular study visits as long as they participate, at which time safety/efficacy data will be collected and recorded. Results: NA Conclusions: Given the potential benefit to mCRC pts, this Phase 3 study will evaluate 90Y in the second-line setting in patients who have progressed following SOC first-line chemotherapy.

Purpose Bortezomib-melphalan-prednisone (VMP) has improved overall survival in multiple myeloma. This randomized trial compared VMP plus thalidomide (VMPT) induction followed by bortezomib-thalidomide maintenance (VMPT-VT) with VMP in patients with newly diagnosed multiple myeloma. Patients and Methods We randomly assigned 511 patients who were not eligible for transplantation to receive VMPT-VT (nine 5-week cycles of VMPT followed by 2 years of VT maintenance) or VMP (nine 5-week cycles without maintenance). Results In the initial analysis with a median follow-up of 23 months, VMPT-VT improved complete response rate from 24% to 38% and 3-year progression-free-survival (PFS) from 41% to 56% compared with VMP. In this analysis, median follow-up was 54 months. The median PFS was significantly longer with VMPT-VT (35.3 months) than with VMP (24.8 months; hazard ratio [HR], 0.58; P < .001). The time to next therapy was 46.6 months in the VMPT-VT group and 27.8 months in the VMP group (HR, 0.52; P < .001). The 5-year overall survival (OS) was greater with VMPT-VT (61%) than with VMP (51%; HR, 0.70; P = .01). Survival from relapse was identical in both groups (HR, 0.92; P = .63). In the VMPT-VT group, the most frequent grade 3 to 4 adverse events included neutropenia (38%), thrombocytopenia (22%), peripheral neuropathy (11%), and cardiologic events (11%). All of these, except for thrombocytopenia, were significantly more frequent in the VMPT-VT patients. Conclusion Bortezomib and thalidomide significantly improved OS in multiple myeloma patients not eligible for transplantation.

637 Background: Trifluridine/tipiracil (FTD/TPI, also known as TAS-102) is approved for the use in patients with chemorefractory mCRC. Inspired by the encouraging results of a small phase I/II study, C-TASK FORCE, evaluating the combination of FTD/TPI and bevacizumab in chemorefractory mCRC patients (Kuboki et al, 2017), we designed the present randomized trial. Methods: This randomized study enrolled as planned 80 mCRC patients. The main inclusion criteria were: histologically confirmed and chemorefractory mCRC; PD during or after therapy with fluoropyrimidine, irinotecan, oxaliplatin, EGFR-inhibitor (RAS wildtype), and bevacizumab was optional; PS 0-1. In arm A, FTD/TPI was administered orally at the dose of 35 mg/m²/dose bid from day 1 to day 5 and from day 8 to day 12 and in arm B the same dose of FTD/TPI was combined with bevacizumab at a dose of 5 mg/kg on day 1 and on day 15 of a 28-day treatment cycle. The primary endpoint was to increase progression-free survival (PFS) from 1.8 months to 3.8 months. Secondary objectives included overall survival (OS) and safety. Results: Eighty patients with chemorefractory mCRC were randomized from September 2017 to August 2018. The median PFS was significantly improved from 2.6 months (arm A) to 5.9 months (arm B) with a hazard ratio (HR) 0.51 (95% CI, 0.28 to 0.92; P < 0.03) and median OS was significantly improved from 7.3 months (arm A) to 10.3 months (arm B) with HR 0.42 (95% CI, 0.18 to 0.99; P < 0.05). After median follow-up for OS of 5.6 months, 57 patients were alive at September 7th, 2018. Therapy was well tolerated with adverse events as expected, patients receiving FTD/TPI + bevacizumab had more grade 3-4 neutropenia (56% in arm B vs 30% in arm A, p = 0.03) and three patients in arm B (vs zero in arm A ) developed febrile neutropenia. SAEs were observed in 13 (arm A) and 11 patients (arm B), respectively. Conclusions: In patients with chemorefractory mCRC, FTD/TPI + bevacizumab, as compared with FTD/TPI monotherapy, was associated with a significant and clinical relevant improvement in PFS and OS with tolerable toxicity.

Abstract BACKGROUND Glioblastoma (GB) is the most aggressive primary brain tumour. Despite the survival benefit associated with adjuvant therapy, most of patients (pts) relapse after initial therapy. Nitrosoureas (NU) are the standard treatment at relapse in Europe. Both fotemustine (FM) (Addeo schema) and lomustine (LM) (administered orally every 6 weeks) are used in this context. MATERIAL AND METHODS This retrospective cohort study included pts diagnosed with GB treated with NU at relapse in four Catalonia hospitals from 2010 to 2020. Clinical and pathological data were collected from medical records. We analysed 6months-progression-free survival (6m-PFS), progression-free survival (PFS) and overall survival (OS) from the start of NU to progression or death respectively. Differences in toxicity grade using CTCAE v5.0 were analysed globally as ‘non-toxicity’, ‘mild toxicity (grade 1 or 2)’ and ‘high toxicity (grade 3 or 4)’. RESULTS We identified 236 GB pts with a median age of 58 years old. 29% of the pts presented MGMT promotor methylation and only 3%(n=7) had IDH mutation. After a median follow-up of 20 months, 94% of the pts were dead at the time of the analyses. At first line, 83 pts were treated with FM and 18 with LM. Pts treated with FM had better performance status (PS) than those treated with LM (p=.010). Median PFS was 2 months and 6m-PFS was 12% vs 6% in FM and LM group respectively (p=.87). Median OS was 3 months with LM vs 6 months with FM, with no statistically significant differences even adjusted for prognostic factors (p=.79 HR:0.9 CI 95% 0.41–1.96).At second line, 78 were treated with FM and 24 with LM, no differences between groups. Median PFS was 2 months in both groups and median OS was 3 vs 5 months for pts treated with LM vs FM respectively, with no significant differences. 6m-PFS was 13% for LM vs 0% for the FM group (p=.39).Pts received a mean of 1.7 cycles (every 6 weeks) and 4.1 cycles (every 2 weeks) in LM and FM group, respectively. Thrombocytopenia was the most common serious side-effect, with a higher proportion of grade 1–2 toxicity in the FM group (p=.03) that also required more treatment delays (p=.01). CONCLUSION Despite being retrospective study and a few pts were treated with LM, there were no differences neither in PFS nor in OS in pts treated with LM vs FM at first or second line. Higher G1-2 thrombocytopenia was shown in the FM group probably due to a higher number of hematology samples collected.

Abstract Purpose: Alemtuzumab (MabCampath) is a humanized monoclonal antibody that targets the CD52 antigen, which is highly expressed on most human B and T lymphocytes. Alemtuzumab has shown considerable activity in both relapsed/refractory CLL and in the frontline treatment setting. In a recent study, treatment with single-agent alemtuzumab induced MRD-negative remissions in 20% of patients with relapsed/refractory CLL (Moreton et al JCO 2005;23:2971–2979). Other studies suggest that MRD negativity can also be attained when alemtuzumab is administered as consolidation for patients with CLL who achieve incomplete initial responses to chemotherapy. Here, we report our long-term experience within a randomized phase III trial that investigates the role of alemtuzumab for consolidation therapy in patients with previously untreated CLL. Methods: Pts in complete or partial remission after induction chemotherapy, with either fludarabine (F) or fludarabine plus cyclophosphamide (FC), were randomized to receive either alemtuzumab 30 mg, 3 times a week for ≤12 wks or no further treatment. Of 21 eligible pts, who had responded to induction with F or FC (1 CR, 1 nPR, 9 PRs), 11 pts (median age: 60 years) randomized to receive alemtuzumab consolidation and 10 to the observation arm. Pts in the alemtuzumab arm received standard premedication and infection prophylaxis with famciclovir and trimethoprim/sulfamethoxazole. Results: After a median follow-up of 48 months, calculated from time of randomization within this consolidation trial, progression-free survival (PFS) was significantly improved for pts who received alemtuzumab consolidation compared to those who received no further treatment (median PFS not reached versus 20.6 months, P = 0.004). PFS from the beginning of induction therapy with F or FC is also significantly greater for patients in the alemtuzumab consolidation arm versus the observation arm. So far, 3 of 11 pts presented with disease progression after alemtuzumab consolidation compared with 8/10 progressing pts in the observation arm. Differences in PFS between both arms were not associated with disease stage before first line treatment, type of first line chemotherapy (F vs. FC) or response status before initiation of consolidation therapy (CR vs. nPR vs. PR). Correlations between achievement of MRD negative responses and PFS is still under investigation and is planned for presentation. With the exception of 2 patients (1 pt in each arm) all patients remain alive. The study was stopped prematurely due to severe infections (7 CTC III infections, which included 4 CMV reactivations, 1 CTC IV infection) in 7/11 patients being treated with alemtuzumab. However, these infections were successfully treated, not associated with the cumulative dose of alemtuzumab, and no late complications of consolidation therapy have been observed. Conclusions: Although based on few pts due to incomplete accrual, long-term PFS was significantly prolonged in patients with CLL receiving alemtuzumab consolidation after first line chemotherapy with F or FC. An ongoing phase I/II trial of the GCLLSG (CLL2i) is currently evaluating the optimal dose and schedule of alemtuzumab in CLL pts after fludarabine-based chemotherapy.

Abstract Abstract 350 Background. The incorporation of new drugs as induction therapy before autologous transplantation appears to produce a high proportion of complete responses, slightly superior to those achieved by conventional chemotherapy with new drugs. Randomized trials are needed to directly compare current best chemotherapeutic approach with best autologous transplantation strategy. Aims. To compare melphalan, prednisone and lenalidomide (MPR) with tandem melphalan (200 mg/m2) (MEL200) in patients younger than 65 years. Methods. As induction, all (N=402) patients received four 28-day cycles of lenalidomide (25 mg days 1-21) and low-dose dexamethasone (40mg days 1,8,15,22) (Rd). Cyclophosphamide (4 g/m2) plus granulocyte-colony stimulating factor was used to mobilize stem cells. As consolidation, patients (N=202) randomized to MPR received six 28-day cycles of melphalan (0.18 mg/kg days 1-4), prednisone (2 mg/kg days 1-4) and lenalidomide (10mg days 1-21); patients (N=200) randomized to MEL200 received tandem melphalan 200 mg/m2 with stem-cell support. All patients were also randomized to receive either aspirin or low-molecular weight heparin (enoxaparin) as thromboprophylaxis. Primary end point was progression-free survival; data were analyzed in intention-to-treat. Results. Patient characteristics were similar in both groups, median age was 58 years. After Rd induction, at least partial response (PR) rate was 84%, at least very good partial response (VGPR) was 32% including 5% complete response (CR). The median yields of CD34+ cells harvested was 10 ×106 CD34+ cells/Kg; 94% of patients collected the minimum dose of 2×106/kg CD34+ cells. After 3 cycles of MPR, at least VGPR rate was 51% and CR 11%. After the first MEL200, at least VGPR rate was 56% and CR 14%. No difference in responses were reported according to cytogenetic abnormalities, such as del13, t(4;14) and t(14;16). After a median follow-up of 12 months, 1-year progression-free survival was 96% for MPR and 94% for MEL200 (p=.92) 1-year overall survival was 98% for MPR and 99% for MEL200 (p=.94). During Rd induction, the most frequent grade 3-4 adverse events were neutropenia (9%), anemia (8%), infections (4%), skin rash (4%), fatigue (2%) and thromboembolic events (1%). During consolidation, the incidence of grade 3-4 neutropenia (97% vs 34%, p <.001) thrombocytopenia (97% vs 16%, p<.001), infections (21% vs 3%, p<.001) and gastrointestinal (17% vs 1%, p<.001) complications was higher in MEL200 patients The incidence of thromboembolic events was similar in patients randomized to receive aspirin (2%) or enoxaparin (1%) as thromboprophylaxis (p=.42). Conclusion. Rd is an effective and safe induction regimen. Both MPR andMEL200 improved the quality of response, achieved by Rd induction. At present, progression-free and overall survival are not significantly different in the two groups, but longer follow-up is needed. Both aspirin and enoxaparin were equally effective as thromboprophylaxis. These data will be updated at the meeting. Disclosures: Palumbo: CELGENE: Honoraria. Cavallo:CELGENE: Honoraria.
