9582 Background: The phase III KEYNOTE-189 study (NCT02578680), showed significant improvements in OS and PFS with pembro + chemo vs placebo + chemo in pts with previously untreated metastatic nonsquamous NSCLC without sensitizing EGFR/ALK mutations. We report the protocol-specified final analysis of KEYNOTE-189. Methods: Pts were randomized 2:1 to receive 35 cycles of pembro 200 mg Q3W (n = 410) or placebo Q3W (n = 206) plus 4 cycles of pemetrexed (pem) and carboplatin/cisplatin followed by maintenance pem. Pts in the placebo + chemo arm could crossover to pembro upon PD. PFS and OS were primary endpoints; ORR was a secondary endpoint. PFS2 (time from randomization to objective tumor progression on next-line treatment/death), was an exploratory endpoint. Results: At data cutoff (May 20, 2019), median (range) time from randomization to data cutoff was 31.0 (26.5–38.8) mo. 17 pts in the pembro + chemo arm and 1 pt in the placebo + chemo arm were receiving initially assigned treatment; 84 pts crossed over to pembro. Median (95% CI) OS (22.0 [19.5–24.5] vs 10.6 [8.7–13.6] mo; HR 0.56 [95% CI, 0.46–0.69]) and PFS (9.0 [8.1–10.4] vs 4.9 [4.7–5.5] mo; HR 0.49 [95% CI, 0.41–0.59]) were longer with pembro + chemo vs placebo + chemo (Table). The 2-y OS rate was 45.7% vs 27.3% and the 2-y PFS rate was 22.0% vs 3.4%. ORR was 48.3% with pembro + chemo vs 19.9% with placebo + chemo. 56 pts in the pembro + chemo arm completed 35 cycles of pembro among whom ORR was 85.7% (4 CR, 44 PR, 8 SD) and median OS was not reached. 292 (72.1%) pts in the pembro + chemo arm and 135 (66.8%) pts in the placebo + chemo arm had grade 3–5 AEs. Conclusions: Pembro + chemo continued to show improved outcomes in OS, PFS, ORR and PFS2 compared with placebo + chemo, with manageable toxicity. These findings support first-line pembro + chemo in pts with previously untreated metastatic nonsquamous NSCLC. Clinical trial information: NCT02578680 . [Table: see text]

507 Background: ASPECCT demonstrated that panitumumab (pmab) was noninferior to cetuximab (cmab) for overall survival (OS). Ad hoc analyses from ASPECCT suggested that hypomag was associated with better outcomes for pmab and cmab (Price 2015). However, results from the phase 3 NCIC CTG/AGITG CO.17 trial indicated hypomag at day 28 was associated with worse outcomes for cmab (Vickers 2013). Methods: Patients (pts) with chemorefractory WT KRASexon 2 mCRC were randomized 1:1 to receive pmab or cmab. Ad hoc analyses by hypomag were performed from the final analysis of ASPECCT at week 5, consistent with the NCIC CTG/AGITG CO.17 trial analysis (Vickers, 2013). Results: 999 pts were treated: 496 received pmab and 503 received cmab. Any grade hypomag was 29.0% and grade ≥3 was 7.3% in the pmab arm vs 19.3% and 2.8% in the cmab arm, respectively. In the pmab arm, 1.2% of pts discontinued treatment and 5% of pts had dose modifications due to hypomag vs 0.4% and 3% in the cmab arm, respectively. Efficacy results by hypomag are shown (Table). Conclusions: In ASPECCT, rates of hypomag were higher in the pmab vs the cmab arm. Pts who developed any grade hypomag with pmab or cmab had longer median OS compared with those pts who did not. Consistent with previous analyses, development of hypomag at week 5 was associated with worse median OS for cmab. Clinical trial information: NCT01001377. [Table: see text]

LBA2 Background: Gemcitabine-cisplatin (GP) chemotherapy is the standard 1st line treatment for locally advanced, recurrent or metastatic (r/m) NPC. Toripalimab, a humanized IgG4K monoclonal antibody specific for PD-1, provided durable responses in patients (pts) with r/m NPC as monotherapy in the ≥2nd line setting (POLARIS-02 study). The results of JUPITER-02, a randomized, placebo-controlled, double-blinded Phase III trial of toripalimab in combination with GP chemotherapy as first-line treatment for r/m NPC are summarized. Methods: Pts with advanced NPC with no prior chemotherapy in the r/m setting were randomized (1:1) to receive toripalimab 240 mg or placebo d1 in combination with gemcitabine 1000 mg/m2 d1, d8 and cisplatin 80 mg/m2 d1 every 3 weeks (Q3W) for up to 6 cycles, followed by monotherapy with toripalimab or placebo Q3W until disease progression, intolerable toxicity, or completion of 2 years of treatment. Stratification factors were ECOG PS (0 vs. 1) and extent of disease (recurrent vs. primary metastatic) at enrollment. Progression-free survival (PFS) and response were assessed by independent review committee (IRC) per RECIST v1.1. The primary endpoint was PFS by IRC in the ITT population. Secondary end points included ORR, DOR and OS. There was one prespecified interim analysis of PFS at 130 PFS events with a planned final analysis at 200 PFS events. Results: 289 pts were randomized: 146 to the toripalimab arm and 143 to the placebo arm. By May 30, 2020 as the interim analysis cutoff date, the median treatment duration was 39 weeks in the toripalimab arm and 36 weeks in the placebo arm. A significant improvement in PFS was detected for the toripalimab arm compared to the placebo arm (HR = 0.52 [95% CI: 0.36-0.74] two-sided p = 0.0003), with median PFS of 11.7 vs. 8.0 months. The 1-year PFS rates were 49% and 28% respectively. An improvement in PFS was observed across relevant subgroups, including all PD-L1 subgroups. The ORR was 77.4% vs. 66.4% (P = 0.033) and the median DOR was 10.0 vs. 5.7 months (HR = 0.50 [95% CI: 0.33-0.78]). As of Jan 15, 2021, OS was not mature, with 25 deaths in the toripalimab arm and 35 in the placebo arm (HR = 0.68 [95% CI: 0.41-1.14], P = 0.14). The incidence of Grade ≥3 adverse events (AEs) (89.0% vs 89.5%); AEs leading to discontinuation of toripalimab/placebo (7.5% vs 4.9%); and fatal AEs (2.7% vs 2.8%) were similar between two arms; however, immune-related (irAEs) (39.7% vs. 18.9%) and Grade ≥3 irAEs (7.5% vs. 0.7%) were more frequent in the toripalimab arm. Conclusions: The addition of toripalimab to GP chemotherapy as 1st-line treatment for pts with advanced NPC provided superior PFS and ORR and longer DOR than GP alone with a manageable safety profile. These results support the use of toripalimab with GP chemotherapy as the new standard care for this population. Clinical trial information: NCT03581786.

Radiologic Progression

9094 Background: Data from the randomized, phase 2 cohort G of KEYNOTE-021 (NCT02039674) showed that adding pembro to first-line CP in patients (pts) with advanced nonsquamous NSCLC significantly improved the primary end point of ORR (55% vs 29%, P = 0.0016) and the key secondary end point of PFS (HR 0.53, P= 0.0102) compared with CP alone and had a manageable safety profile (grade 3-4 treatment-related AEs, 39% vs 26%; treatment-related AEs leading to discontinuation, 10% vs 13%). We present updated efficacy for cohort G based on 5 mo additional follow-up. Methods: 123 pts with stage IIIB/IV, chemotherapy-naive, nonsquamous NSCLC and no EGFR mutation or ALK translocation were randomized to 4 cycles of carboplatin AUC 5 + pemetrexed 500 mg/m2 Q3W ± 24 mo of pembro 200 mg Q3W; maintenance pemetrexed was permitted in both arms. Eligible pts in the CP arm who had radiologic progression could crossover to pembro monotherapy. Response was assessed per RECIST v1.1 by blinded, independent central review. All Pvalues are nominal. Results: As of Dec 31, 2016, median follow-up was 14.5 mo (range, 0.8-24.0). 36 of 48 pts (75.0%) in the CP arm who discontinued CP received subsequent anti–PD-1 or PD-L1 therapy. There was 1 additional response in each arm, and ORR was 56.7% (95% CI 43.2%-69.4%) with pembro + CP vs 30.2% (95% CI 19.2%-43.0%) with CP ( P = 0.0016). Median DOR was not reached for pembro + CP (range, 1.4+ to 18.6+ mo) and was 16.2 mo (range, 2.8 to 20.7+) for CP alone. PFS remained longer with pembro + CP (HR 0.49, 95% CI 0.29-0.83, P = 0.0035; median [95% CI] NR [9.7 mo-NR] vs 8.9 mo [6.2-10.3]; 12-mo estimate, 56% vs 34%). With 16 deaths in the pembro + CP arm and 23 deaths in the CP arm, HR for OS was 0.69 (95% CI 0.36-1.31, P= 0.13). Median OS was not reached in either arm; at 12 mo, estimated OS was 76% in the pembro + CP arm and 69% in the CP alone arm. Conclusions: With 5 mo additional follow-up, first-line pembro + CP continues to provide a substantial, clinically relevant improvement in efficacy over CP alone in pts with advanced nonquamous NSCLC, including an almost doubled ORR, halved risk of progression or death, and a trend toward improved OS despite a 75.0% crossover rate in the CP arm. Clinical trial information: NCT02039674.

11054 Background: Advanced SyS are rare tumors with limited curative options. FZD10 is highly expressed in SyS but not in normal adult tissue. OTSA101 is a MAb targeting FZD10, labelled with a radioisotope. Methods: We conducted a phase I, FIH study including adult pts with advanced, refractory SyS. In part 1, pts received OTSA101 labelled with In111 used as radiotracer to assess biodistribution and tumor uptake. In part 2, pts with significant tumor uptake were randomized to receive OTSA101 labelled with 370MBq of Y90 (Arm A) or 1110MBq Y90 (Arm B). Primary endpoints were occurrence of unacceptable biodistribution /lack of tumor uptake in part 1 and occurrence of related adverse events (AEs) Grade ≥ 3 during the first 8 weeks following injection of Y90OTSA101 in part 2. Responses were assessed per RECIST 1.1. Results: From January 2012 to June 2015, 20 pts (10 females, median age 43, range 21-67) with advanced SyS were enrolled. Ten pts (50%) had sufficient tumor uptake to proceed to part 2 and 8 were randomized (Arm A: 3 and Arm B: 5). Two pts were not randomized due to worsening PS. During part 2, the most common Grade ≥ 3 AEs were haematological, including reversible lymphopenia, thrombocytopenia and neutropenia, and were more common in Arm B. One pt with SD after 12 weeks received a 2nd injection of 90Y-OTSA101, but experienced fatal hemoptysis. No objective response was observed. Best response was SD in 5/8 pts lasting up to 21 weeks for 1 pt. Conclusions: This FIH shows that radioimmunotherapy targeting FZD10 is feasible and safe in SyS pts. Tumor uptake was heterogeneous but sufficient to select 50% of pts for 90Y-OTSA101 treatment. Due to limited sample size, further clinical investigations are needed to assess the therapeutic activity of 90Y-OTSA101 with a recommended dose of 1110MBq of 90Y. Clinical trial information: NCT01469975.

146 Background: Platinum-doublet chemotherapy in first-line (1L) ESCC pts has reached a therapeutic plateau, and new therapeutic strategies are needed. Adding D (anti-PD-L1 mAb) and T (anti-CTLA-4 mAb) to 1L platinum-based chemotherapy may improve outcome in pts with advanced/metastatic ESCC. Methods: In Part A of this Phase 1b study (NCT02658214), dose-limiting toxicities (DLTs) for D+T (D 1.5 g + T 75 mg on d1, q4w) plus 5-FU+cisplatin (5-FU 800 mg/m2 + cisplatin 80 mg/m2 d1-5, q4w) were evaluated for the first 4 cycles in pts with advanced/metastatic ESCC who were eligible for 1L chemotherapy. The primary objective was safety and tolerability and exploratory objectives included antitumor activity and biomarker analysis. Results: Pts (N = 6) were enrolled to receive D+T + 5-FU+cisplatin between November 13, 2017, and February 14, 2018. Median age was 56 years, 83% were male, and all were ECOG PS 1. Four pts had recurrent disease and 2 were newly diagnosed with advanced/metastatic disease. All 6 pts had ≥1 treatment-related adverse event (trAE), 3 pts had grade ≥3 trAEs. All pts experienced 5-FU+cisplatin-related AEs. All grade ≥3 trAEs were neutropenia and considered due to 5-FU+cisplatin treatment; 2 were grade 3 and 1 was grade 4, which was the only serious trAE reported. Two pts had D- and/or T-related trAEs. Immune-mediated AEs were grade 1 or 2 and included diarrhea (n = 1), pruritus (n = 1), rash (n = 1), and increased AST (n = 1). There were no trAEs that led to discontinuation or death. Two of the 6 pts had a confirmed partial response that was ongoing at data cutoff (June 29, 2018). Conclusions: For patients in the ESCC DLT evaluation cohort, D+T + 5-FU+cisplatin was tolerable, and no unexpected toxicities occurred. No DLTs were observed for this regimen. The majority of trAEs and all trAEs grade ≥3 were attributed to 5-FU+cisplatin, and all were manageable. AEs related to D and/or T were all grade 1 or 2. No treatment discontinuation or death was attributed to trAEs. The study has been expanded to further evaluate this regimen in additional patients for efficacy, safety, and biomarkers. Clinical trial information: NCT02658214.

LBA4007 Background: KEYNOTE062 (NCT02494583) was a randomized, active controlled study of 1L P or P+C vs C in pts with PD-L1 combined positive score ≥1 (CPS ≥1), HER2-negative, advanced GC. Methods: Eligible pts were randomized 1:1:1 to P 200 mg Q3W for up to 2 y, P+C (cisplatin 80 mg/m2 + 5-FU 800 mg/m2/d on d1-d5 Q3W [or capecitabine 1000 mg/m2 BID on d1-d14 Q3W per local guideline]) or placebo Q3W + C. Randomization was stratified by region, disease status, and fluoropyrimidine treatment. Primary endpoints were OS in CPS ≥1 and CPS ≥10 for P+C vs C and P vs C and PFS (RECIST v1.1; central review) in CPS ≥1 for P+C vs C. ORR (RECIST v1.1; central review) in CPS ≥1 for P+C vs C was the secondary endpoint. Final analysis cutoff date was 26 Mar 2019. Results: 763 pts (281 with CPS ≥10) were randomized to P+C (257), P (256), or C (250) (Table). Median follow-up was 11.3 mo. P was noninferior to C for OS in CPS ≥1 per prespecified margins. P vs C prolonged OS in CPS ≥10 (median 17.4 vs 10.8 mo; HR 0.69; 95% CI 0.49-0.97) but wasn’t tested per analysis plan. P+C vs C was not superior for OS in CPS ≥1 or CPS ≥10, with a favorable trend for P+C. P+C did not significantly prolong PFS in CPS ≥1. ORR was higher for P+C vs C. Grade 3-5 drug-related AE rates were 17% (P), 73% (P+C), and 69% (C). Conclusions: As 1L therapy for advanced GC, P was noninferior to C for OS in CPS ≥1 with clinically meaningful improvement for OS in CPS ≥10. P+C did not show superior OS and PFS in CPS ≥1 and OS in CPS ≥10. The safety profile was more favorable for P vs C. Clinical trial information: NCT02494583. [Table: see text]

547 Background: N+I showed superior OS v S in ITT (IMDC any risk) and intermediate/poor-risk (I/P) pts with aRCC in CheckMate 214 at 17.5 mo min follow-up. Methods: Pts with clear cell aRCC were randomized 1:1 to N3 mg/kg + I1 mg/kg Q3W×4 and then N3 mg/kg Q2W, or S 50 mg daily for 4 wk on, 2 wk off. Co-primary endpoints were OS, RECISTv1.1 ORR and PFS per IRRC in I/P pts. PFS and ORR were assessed by investigator (inv) at 30 mo. Results: At 30 mo min follow-up, OS remains significantly improved in ITT and I/P pts with N+I v S; the HR for OS in favorable (fav) risk pts has improved for N+I v the previous analysis (1.22 [95% CI 0.73–2.04] v 1.45 [99.8% CI 0.51‒4.12]). Per previous IRRC ORR (N+I, 42% [95% CI 37‒47]; S, 27% [95% CI 22‒31]), ORR per inv was higher with N+I v S in ITT and I/P pts. ORR CIs overlapped in fav pts, CR was doubled with N+I v S. Increasing PFS benefit with N+I v S is emerging in ITT and I/P pts; PFS CIs between arms remain overlapping in fav pts (Table). 15% v 9% of N+I and S ITT pts remain on therapy, and 48% v 61% have received 2nd-line systemic therapy; 39% of S pts received subsequent immune-checkpoint inhibitor therapy. Among pts who were alive with CR, 50% v 10% remain on treatment with N+I (n = 56) v S (n = 10). 5 N+I and 7 S additional pts developed Gr 3–4 drug-related AEs; 1 N+I and 3 S additional pts had AEs leading to discontinuation. No new drug-related deaths occurred. Conclusions: At 30 mo min follow-up, OS and ORR remain improved with N+I v S in ITT and I/P CheckMate 214 pts. No new safety signals emerged with longer follow-up. Clinical trial information: NCT02231749. [Table: see text]

Abstract Background: For many years the ALFA Group has used high dose DNR, i.e 80 mg/m2/day for 3d as part of the induction regimen for untreated adult AML pts. As the equivalence of DNR and Ida is not known we conducted a phase III study to compare high dose DNR to Ida. We also tested the effect of IL2 for maintenance. Methods: Newly diagnosed AML, aged 50 to 70 years, were randomized to receive AraC 200 mg/m2/day IV x 7 d with either DNR: 80 mg/m2/d x 3 d (arm 1) or Ida: 12 mg/m2/d x 3 d (arm 2) or x 4 d (arm 3). Pts who failed could receive a salvage course with Mitoxantrone x 2 d and AraC1g/m2 12 hrs x 4d. Response was assessed after induction+/− salvage chemotherapy. CR pts received 2 consolidation courses according to the induction arm with DNR: 80 mg/m2 or Ida:12 mg/m2 for 1 day (first course) or 2 days (2nd course) and AraC:1g/m2/12 hrs x 4 days. Pts in CCR after the two consolidation courses were randomized to receive or not a maintenance immunotherapy with IL2: 5.106/m2 for 5 days monthly for12 months. Results: From 2001 to 2006, 468 pts were included (median age: 60 years). The 3 treatment arms were well matched for pretreatment characteristics. CR was achieved in 360/468 pts (77%): 109 (70%) pts arm 1, 129 (83%) arm 2, 122 (78%) arm 3 (p=0.02).70 pts, (45%) pts in the DNR arm reached CR after 1 course vs 97 (62%) and 90 (57%) in Ida arms (p= 0.006). Pts in Ida arms experienced more grade 3 or 4 mucositis (p=0.004) but no differences were observed between the 3 arms for duration of hospitalization, time to PMN or plts recovery, incidence of grade 3 or 4 infectious episodes and treatment related mortality. 3 year cumulative incidence of relapse was 69%, 63%, 62% resp in arms 1,2,3 (p=NS). 3 year EFS was 19%, 30%, 26% resp (p=0.06 for arm 1 vs arms 2 and 3). 3 year OS was 31%, 40% 41% resp in arms 1,2,3 (p=NS). Age (< or >60 years), sex, initial WBC counts, initial LDH (nl or >nl), DNR or Ida arms, need for a salvage course were not predictive for relapse, while 2yCIR was 43%, 64%, 77% among respectively fav, intermediate and unfav cytogenetic risk groups resp (p=0.0046). Of the 219 pts alive in CR after consolidations, 161 (73%) were randomized for maintenance. Only 22 of the 77 pts randomized for IL2 completed the 1 year treatment. 32 and 23 pts stopped IL2 resp because of relapse or intolerance. There were no differences in relapse or OS in both maintenance arms. Conclusion: Ida treatment even when compared to high doses of DNR yields higher CR rate and more CR after one course. This effect translated in slightly better EFS but not better CIR or OS. IL2 maintenance treatment at least as scheduled in this trial was difficult to apply and showed no impact on disease course.

Abstract Abstract 405 Introduction: Promising results have been observed in two phase-II studies evaluating the combination of Bendamustine plus Rituximab (B-R) in patients with relapsed/refractory indolent or mantle cell lymphomas (Rummel et al., JCO 2005; Robinson et al., JCO 2008). In order to further investigate the role of the combination B-R we initiated a multicenter randomized phase-III study in October 2003 to compare efficacy and safety of B-R versus CHOP plus Rituximab (CHOP-R) as first-line therapy for patients with follicular (FL), indolent and mantle cell lymphomas (MCL). Patients and Methods: 549 patients (pts) in need of treatment for their disease were randomized to receive Rituximab 375 mg/m2 (day 1) plus either Bendamustine 90 mg/m2 (days 1+2) every 28 days or the standard CHOP regimen every 21 days for a maximum of 6 cycles. The primary endpoint was progression-free survival (PFS). Patients characteristics, including age, stage, LDH, IPI, FLIPI, bone marrow infiltration and extranodal involvement did not statistically significant differ between both arms. The median patient age was 64 years (range 31-83) (64 yrs for B-R and 63 yrs for CHOP-R). Most patients were in stage IV (76,9% in BR and 77,5 in CHOP-R) and stage III (19,2% in B-R and 18,6% in CHOP-R). Histologies were distributed equally between B-R and CHOP-R: follicular 55% and 56%, mantle cell 18% and 19%, and other indolent lymphomas 27% and 24%, respectively. Prophylactic use of antibiotics or growth factors were not generally recommended in this protocol. Results: Of the 549 pts 36 pts were not evaluable: 10 did not receive any study medication, 9 due to withdrawal of consent, 13 due to incorrect diagnosis (4 × DLBCL, 3 × CLL, 2 × MM, 1 × HD, 3 × solid tumors), and 4 for other reasons. 513 randomized pts are evaluable for the final analysis (B-R: n=260; CHOP-R: n=253). Out of these 9 pts were not evaluable for response evaluation: 4 pts (3 × CHOP-R, 1 × B-R) due to early death in neutropenic sepsis, 3 pts due to a subsequent change of therapy after severe toxicity in 1st cycle of CHOP-R, 1 B-R pt due to progress of disease, and 1 B-R due to early death. All patients were counted for evaluation of PFS, overall survival (OS), event-free survival (EFS; an event was defined by a response less than a partial response, disease progression, relapse, or death from any cause), and for time to next treatment (TTNT). A median number of 6 cycles was given in both treatment arms each. 82% of B-R pts and 86% of CHOP-R pts received 6 cycles. At the time of analysis in August 2009, the median observation time was 32 months. Overall response rate for pts treated with B-R was similar to the CHOP-R group (93,8% vs 93,5%, respectively). The CR rate was significantly higher with 40,1% for B-R compared to 30,8% for CHOP-R (p=0.0323). The median PFS, EFS and TTNT were significantly longer after B-R compared to after CHOP-R: PFS 54,8 months for B-R versus (vs) 34,8 months for CHOP-R (p=0.0002), Hazard Ratio (HR) 0.5765 (95% confidence interval (CI) 0.4292 to 0.7683); EFS 54 months for B-R vs 31 months for CHOP-R (p=0.0002, HR 0.6014 (95% CI 0.4515 to 0.7845); and TTNT median not yet reached in the B-R group vs 40,7 months in the CHOP-R group (p=0.0002; HR 0.5416, 95% CI 0.3897 to 0.7491). OS did not differ between both groups at this point of time. Thus far, 67 deaths have been observed (B-R: 34; CHOP-R: 33). CHOP-R treatment was more frequently associated with serious adverse events (SAE) (n=49 in B-R vs n=74 in CHOP-R). Significant differences in hematologic toxicities were observed for neutropenia grade 3+4 (BR 10,7% vs CHOP-R 46,5%; p<0.0001) and for leukocytopenia grade 3+4 (BR 12,1% vs CHOP-R 38,2%; p<0.0001). G-CSF was more often used in CHOP-R treated pts (20,0% of all cycles) than it was used in the B-R group (4,0%) (p<0.0001). The B-R regimen was better tolerated by the pts as evidenced by a lower rate of alopecia (15% (only grade 1) in B-R vs 62% CHOP-R), a lower number of infectious complications (95 in BR vs 121 in CHOP-R, p=0.0403), a lower incidence of peripheral neuropathy (B-R n=18; CHOP-R n=73; p<0.0001), and fewer episodes of stomatitis (B-R n=16; CHOP-R n=47; p<0.0001). Only drug-associated erythematous skin reaction (urticaria, rash) was more often seen with B-R (n=42) than with CHOP-R (n=23) (p=0.0122). Conclusions: In this final analysis the combination of Bendamustine plus Rituximab improves PFS and CR rates while showing a better tolerability profile. These promising results suggest that B-R does have the potential to become a new standard first-line treatment option for patients with FL, MCL, and indolent lymphomas.

248 Background: Effective treatment for pts with advanced UC unfit to receive cisplatin-based therapy remains an unmet need. A recent phase III study showed limited benefit of gemcitabine-carboplatin (GC) alone (median OS 9.3 months) (DeSantis ASCO 2010). We recently identified the VEGF-axis as a viable pathway for UC treatment (JCO 2010;Mar 10). We propose that bevacizumab, a monoclonal antibody against VEGFR, may be safely added to GC and improve time to progression (TTP) in pts with advanced UC. Methods: Primary endpoints (N=47 planned enrollment) were median TTP, to test an improvement of 50% over a 4.8 months median TTP seen with GC alone (Urology 2004;64:479), and safety. Secondary endpoints were response rate (RR) and overall survival (OS). Pts first received a single dose of bevacizumab 10 mg/kg. 2 weeks later they received 6 cycles of gemcitabine 1,000 mg/m2 on day(D) 1 and D 8, and both carboplatin AUC 4.5 and bevacizumab 15 mg/kg on D1 every 21 days. Pts who achieved at least stable disease were eligible to receive maintenance bevacizumab at 15 mg/kg q21 days for 18 additional doses. Restaging evaluations were performed after every 3 cycles of therapy. Results: 51 pts (37 M, 14 F; median age 67 (Range 42-83)) were enrolled from 6/06 to 6/10. Primary tumor sites include bladder (31), renal pelvis (17) and ureter (2). 38 pts (74.5%) had visceral disease including lung (22), liver (13), bone (9) and adrenal (2). 13 pts had LN only disease. 46 of 51 pts were evaluable for response rate (RR) and TTP, 51 for toxicity. RR by RECIST was 46% (21 pts; PR 18, CR 3). 12 achieved stable disease; 1 too early to assess. Responses by MSKCC Risk Scores of 0, 1 and 2 were seen in 8/11(73%), 10/29 (35%), and 3/6 (50%) pts, respectively. 39% of pts had grade 3/4 toxicity, notably vascular thromboembolic events (VTE) in 18%. Conclusions: Bevacizumab can be safely added to GC in the treatment of advanced UC. The 16% VTE rate is similar to the 17% rate seen at MSKCC with GC alone. (JCO 2009;27:15s). Addition of bevacizumab does not improve the RR seen with GC alone in phase II and III studies (Bellmunt Eur J Cancer 2001; DeSantis ASCO 2010). Analysis of bevacizumab's impact on TTP and OS is ongoing and will be updated. [Table: see text]
