332 Background: Vinflunine (VFL) is the first agent to show a survival improvement for platinum-refractory patients (pts) with metastatic TCCU in a phase III clinical trial. After EMA approval in September 2009, ESMO (Bellmunt, 2011) and SOGUG (Castellano, 2012) guidelines recommend VFL as second-line therapy. Methods: This is a multicenter and retrospective study to describe the experience with VFL in Spain. Pts with histologically confirmed metastatic TCCU were treated with VFL (280-320mg/m2 every 3 weeks) until progression or unacceptable toxicity. Pts were evaluated according to institutional local follow-up program. Results: From April 2010 to June 2013, we registered 102 pts in fifteen Spanish centers. All patients are evaluable for safety and 98 for efficacy. Median age: 67years (range 45-83), ECOG 0/1/2 previous to VFL (pts%): 31/61/8. Bladder carcinoma was the primary disease site in 84 pts and 46 % of them received cisplatinum-based chemotherapy. Metastatic involvement was: lymph nodes 67.7%, lung 36.4%, bone 28.1%, and liver 21.6%. The median number of cycles of VFL was 4 (1-18). The objective response rate was 25.5% (CR in 2 pts and PR in 23 pts), stable disease in 42.9% and progressive disease in 31.6%. The median follow-up was 6.6 months (0.4 to 43): median progression-free survival 3.9 months (95% CI, 2.3 to 5.5), median time to progression 4.3 months (95% CI, 2.6 to 5.9) and median overall survival 10 months (95% CI, 7.3 to 12.8). At the time of the analysis, 79.4%pts had progressive disease after VFL and 64.7% died. Grade 3/4 adverse events included: nausea/vomiting 13.8% of pts, neutropenia 12.8%, constipation 5.9%, and abdominal pain 4.9%. No toxic death were reported. Conclusions: This retrospective analysis confirms the benefit of VFL in patients with TCCU after failure in a platinum-containing chemotherapy regimen. Results of the randomized trial are reproducible in Spanish Oncology Centers on a daily clinical practice and its toxicity profile results are acceptable and manageable.

5031 Background: We present the efficacy data from a phase III study of topotecan (T) plus carboplatin (C) versus standard therapy with paclitaxel plus carboplatin (PC) or gemcitabine plus carboplatin (GC) or carboplatin plus pegylated doxorubicin (PLDC). Methods: From 02/07 to 12/09, 590 pts were screened and 550 pts were randomized to either T (0.75mg/m²/d1-3/q21d) + C (AUC 5/d1/q21d) or to standard therapy with CP or GC or PLDC based on patient preference. Progression free survival at 1 year was defined as primary endpoint. Results: Median number of cycles was 6 (range 0-9) in both arms. Most patients preferred GC (78%) in the standard therapy arm.. Best Response (CR+PR) was 73.1% (95%CI) and 75.1% (95%CI) for the CA. Median follow-up was 18 (0-52) months for TC and 20 (0-48) months for standard therapy. TC failed to show any advantage regarding 1-yr.-PFS or OAS. Conclusions: The combination of topotecan plus carboplatin failed to improve PFS or OAS in platinum sensitive relapsed ovarian cancer. In addition, carboplatin plus gemcitabine was well tolerated with lower rates of severe and long-lasting (neuropathy) toxicities compared to paclitaxel-carboplatin. [Table: see text]

446 Background: Several PD-1 immune-checkpoint inhibitors including Nivolumab (Nivo) are approved in urothelial cancer. Recently, in the front line setting, improved activity of combined PD-L1 and CTLA4 immune-checkpoint inhibition has been reported and a phase III trial with Nivolumab + Ipilimumab (Nivo+Ipi) is ongoing. Here we report a response-based tailored approach starting treatment with Nivo monotherapy using Nivo+Ipi as immunotherapeutic “boost”. Methods: Between July 2017 and April 2019 86 patients were enrolled and treated according to protocol version 3 (cohort 1). Patients started with Nivo 240 mg Q2W induction. After 4 dosings and tumor assessment at week 8 (i) responders (PR/CR) to Nivo monotherapy continued with maintenance while (ii) patients with stable (SD) or progressive disease (PD) received 2 cycles Nivo3+Ipi1 followed by another 2 cycles Nivo1+Ipi3 if not responding. Median follow-up is 8.7 months. The primary endpoint is confirmed investigator-assessed objective response rate (ORR) per RECIST1.1. Secondary endpoints include activity of Nivo monotherapy at week 8, remission rate with Nivo+Ipi “boosts”, safety, overall survival and quality of life. Results: Of the patients 42, 39 and 5 were first, second and third line, respectively. Median age was 67 years (range 45-84), 61 patients (71 %) were male and 25 female. ORR with Nivo monotherapy at first assessment (week 8) was 29 % and 23 % in first and second/third line, respectively. Of the patients 41 received Nivo+Ipi “boosts” after week 8 while 12 received later “boosts”. Best overall response (BOR) rate with Nivo induction ± Nivo+Ipi “boosts” was 48 % and 27 % in first and second/third line, respectively. In first line 7/17 (41 %) patients receiving Nivo+Ipi after week 8 had an improved response compared to 2/24 (8.3 %) in second/third line. Of the patients who continued with Nivo maintenance after week 8 and received later “boosts” 2/12 (17 %) had a PR and 2/12 (17 %) improved to SD. Treatment-related AEs will be presented. Conclusions: TITAN–TCC explores a response-driven use of Nivo+Ipi as an immunotherapeutic “boost”. In first line, this significantly improved ORR compared to the expected response rate of Nivo monotherapy, providing further evidence to the added value of Ipi in combination with Nivo. Further follow-up is ongoing to characterize duration and depth of response. Clinical trial information: NCT03219775 . Research Sponsor: Bristol-Myers Squibb[Table: see text]

302 Background: In the phase III JAVELIN Renal 101 trial (NCT02684006), A + Ax demonstrated progression-free survival (PFS) and objective response rate (ORR) benefit across IMDC risk groups (favorable, intermediate, and poor) vs S in patients with previously untreated aRCC. Here we report efficacy of A + Ax vs S by number of IMDC risk factors (0, 1, 2, 3, and 4-6) and target tumor sites (1, 2, 3, and ≥4) at baseline from the second interim analysis of overall survival (OS). Methods: Patients were randomized 1:1 to receive A 10 mg/kg intravenously every 2 wk + Ax 5 mg orally twice daily or S 50 mg orally once daily for 4 wk (6-wk cycle). PFS and ORR per independent central review (RECIST 1.1) and OS were assessed. Results: At data cut-off (Jan 2019), median (m) follow-up for OS and PFS was 19.3 vs 19.2 mo and 16.8 vs 15.2 mo for the A + Ax vs S arm, respectively. The table shows OS, PFS, and ORR by number of IMDC risk factors and target tumor sites at baseline. A + Ax generally demonstrated efficacy benefit vs S across subgroups. Conclusions: With extended follow-up, A + Ax generally demonstrated efficacy benefit vs S across the number of IMDC risk factors and tumor sites at baseline in aRCC. OS was still immature; follow-up for the final analysis is ongoing. Clinical trial information: NCT02684006 . [Table: see text]

427 Background: Pts with advanced gastric/gastroesophageal junction (G/GEJ) cancer received pembro monotherapy (200 mg Q3W) 3L+ in cohort 1 of KEYNOTE-059 (NCT02335411), 2L in KEYNOTE-061 (NCT02370498), or 1L in KEYNOTE-062 (NCT02494583). We present efficacy data for patients with PD-L1 combined positive score (CPS) ≥10 tumors in these trials. Methods: In study 059, 46 pts in cohort 1 with PD-L1 CPS ≥10 received pembro. In study 061, 108 pts with PD-L1 CPS ≥10 received pembro (n=53) or chemotherapy (chemo; n=55). In study 062, 182 pts with CPS ≥10 received pembro (n=92) or placebo + chemo (n=90). Efficacy end points included overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and duration of response (DOR). Results: Median follow-up in study 059 was 5.6 mo. Median OS with pembro was 7.9 mo (95% CI, 5.8-11.1), and 12-mo OS was 32.6%. PFS at 6 mo was 17.4%, ORR was 17.4%, and median DOR was 20.9 mo (2.8+ to 34.9+). In study 061, after a median follow-up of 8.8 mo, pembro prolonged OS vs chemo (median 10.4 vs 8.0 mo; HR, 0.64; 95% CI, 0.41-1.02); 12-mo OS was 45.3% for pembro and 23.6% for chemo. Median PFS was 2.7 mo for pembro and 3.4 mo for chemo (HR, 0.86; 95% CI, 0.56-1.33). ORR was 24.5% vs 9.1%, and median DOR was NR (4.1-26.0+) and 6.9 mo (2.6-6.9) for pembro vs chemo. In study 062, median follow-up was 17.4 mo for pembro and 10.8 mo for chemo. Pembro prolonged OS vs chemo (median 17.4 vs 10.8 mo; HR, 0.69; 95% CI, 0.49-0.97); 12-mo OS was 56.5% vs 46.7%. Median PFS was 2.9 mo vs 6.1 mo (HR, 1.09, 95% CI, 0.79-1.49). ORR was 25.0% vs 37.8%, and median DOR was 19.3 mo (1.4+ to 33.6+) vs 6.8 mo (1.5+ to 30.4+) for pembro vs chemo, respectively. Conclusions: Collectively, these data indicate that 1L, 2L, and 3L+ pembro monotherapy showed clinically meaningful efficacy in CPS ≥10, with a more durable response than chemotherapy.

437 Background: The optimal perioperative chemotherapy regimen for patients (pts) with MIUBC is not defined. Methods: Between February 2013 and February 2018, 494 pts were randomized in 28 French centres and received either 4 cycles of GC every 3 weeks or 6 cycles of dd-MVAC every 2 weeks before surgery (neoadjuvant group) or after surgery (adjuvant group). The primary endpoint was the progression-free survival at 3 years. Secondary endpoints included toxicity, pathological responses and overall survival. Results: In the neoadjuvant group, 218 pts received dd-MVAC and 219 pts GC. The median number of cycles was 6 (0-6) and 4 (1-4), respectively. 60% of pts received 6 cycles in the dd-MVAC arm, 84% received 4 cycles in the GC arm. 199 pts (91%) and 198 (90%) pts underwent surgery, respectively. Complete pathologic responses (ypT0pN0) were observed in 84 (42%) and 71 (36%) pts, respectively (p=0.02). An organ-confined status (<ypT3pN0) was obtained in 154 (77%) and 124 (63%) pts, respectively (p=0.002). In the adjuvant group (57 pts), the median number of cycles was 5 (1-6) and 4 (1-4), respectively. 40% of pts received 6 cycles in the dd-MVAC arm, 60% received 4 cycles in the GC arm. Most of CTCAE grade ≥ 3 toxicities concerned hematological toxicities. At least one of these where reported for 125 (50%) pts in the dd-MVAC group and 134 (54%) pts in the GC group (p=NS). Gastrointestinal (GI) grade ≥ 3 disorders were more frequently observed in the dd-MVAC arm (p<0.0001) as well as grade ≥ 3 asthenia (p<0.00001). Four deaths (3 in the dd-MVAC) occurred during chemotherapy. Conclusions: Complete pathological responses and organ-confined status were more frequently observed in the dd-MVAC arm. Toxicity was manageable with more severe asthenia and GI side effects in the dd-MVAC arm. Clinical trial information: 2012-000563-25.

Abstract Background: Amplification of EGFR and its active mutant EGFRvIII are common in glioblastoma (GB). While EGFR and EGFRvIII play critical roles in pathogenesis, targeted therapy with EGFR-tyrosine kinase inhibitors (TKIs) or antibodies has shown limited efficacy. To improve the likelihood of effectiveness, we targeted adult patients with recurrent GB enriched for simultaneous EGFR amplification and EGFRvIII mutation, with osimertinib/bevacizumab at doses described for non-small cell lung cancer (NSCLC). Methods: We retrospectively explored whether previously described EGFRvIII mutation in association with EGFR gene amplification could predict response to osimertinib/bevacizumab combination in a subset of 15 patients treated at recurrence. The resistance pattern in a subgroup of subjects is described using a commercial NGS panel in liquid biopsy.Results: There were ten males (66.7%), and the median patient’s age was 56 years (range 38-70 years). After their initial diagnosis, 12 patients underwent partial (26.7%) or total resection (53.3%). Subsequently, all cases received IMRT and concurrent and adjuvant temozolomide (TMZ; the median number of cycles 9, range 6-12). The median follow-up after recurrence was 17.1 months (95% CI 12.3-22.6). All patients received osimertinib/bevacizumab as a second-line intervention with a median progression-free survival (PFS) of 5.1 months (95% CI 2.8-7.3) and overall survival (OS) of 9.0 months (95% CI 3.9-14.0). The PFS6 was 46.7%, and the overall response rate (ORR) was 13.3%. After exposure to the osimertinib/bevacizumab combination, the main secondary alterations were MET amplification, STAT3, IGF1R, PTEN, and PDGFR.Conclusions: While the osimertinib/bevacizumab combination was marginally effective in most GB patients with simultaneous EGFR amplification plus EGFRvIII mutation, a subgroup experienced a long-lasting meaningful benefit. The findings of this brief cohort justify the continuation of the research in a clinical trial. The pattern of resistance after exposure to osimertinib/bevacizumab includes known mechanisms in the regulation of EGFR, findings that contribute to the understanding and targeting in a stepwise rational this pathway.

575 Background: VG has shown to be efficacious and safe in MBC in pts previously treated with AT. This study compared treatment (TT) V with the combination of VG. Primary objective was progression free survival (PFS). Methods: pts previously treated with AT, aged ≥18, ECOG ≤ 2, were randomized to V: 30 mg/m2 day (d) 1, d8, or VG 30/1200 mg/m2 d1, d8, both every 21 days until disease progression. Stratification criteria were previous lines of TT for MBC (0 vs.1 vs.2) and visceral disease (yes vs. no). 126 pts per arm were needed to demonstrate a prolongation in PFS of 2 months (m) (from 3 to 5; HR = 1.67; α and β errors 0.05 and 10). Results: 252 pts (127 V and 125 VG) were recruited between 2001 and 2005. Arms were well balanced: median age was 57 years; median number of metastatic sites 2; visceral disease was present in 75% of pts; 17%, 53% and 29% of pts received study TT as first, second and third line respectively. Median number of cycles were 4 (1–21) in V and 6 (1–26) in VG. Median PFS was 6.3 m (95% CI, 5.3–7.3) for VG and 4.1 m (95% CI, 3.3–4.9) for V (p=0.0011). Objective response rate was 37% (CI 95% 29–46) for VG and 25% (CI 95%: 17–33) for V (p= 0.035). CTC grade 3–4 hematologic toxicity was significantly higher with VG vs. V (65% vs. 43% neutropenia, 33% vs. 17% leucopenia, and 11% vs. 2% thrombocytopenia); febrile neutropenia was present in 10.5% of pts on VG and 6% of pts in V (p=ns). Non-hematological toxicity was low and manageable in both arms. Conclusions: VG demonstrated significant efficacy advantages over V in pts with MBC previously treated with AT, with manageable toxicity. This favorable risk-benefit profile supports the use of this combination in this patient population. [Table: see text]

e14137 Background: We conducted a phase II trial of gemcitabine with S-1 to evaluate the activity and toxicity of such a combination in heavily pre-treated patients (pts) with metastatic colorectal cancer (mCRC) who have progressed after treatment with 5-fluorouracil, oxaliplatin and irinotecan. Methods: Between Dec 2009 and Nov 2011, 23 pts were enrolled, with the following characteristics: 12 males and 11 females, median age 57 years (28-72). S-1 was given orally (30 mg/m2) b.i.d for 14 consecutive days and gemcitabine (1000 mg/m2) was given on days 1 and 8, every 21 days, until disease progression and for a maximum of 9 cycles. The primary endpoint was objective response rate (ORR). Results: The median number of cycles was four (range 1-9). OR was 8.7% (95% confidence interval [CI] 0-20.2) and disease control rate was 56.5% (95% CI 36.4-76.9) with two partial responses and eleven stable diseases. Median duration of disease control was 8.5 months (95% CI 3.8-13.2). Median progression-free survival was 3.2 months (95% CI 1.9-4.5) and median overall survival was 11.8 months (95% CI 4.0-19.5). Grade 3-4 toxicities were neutropenia (8%) and thrombocytopenia (4%). Conclusions: Combination chemotherapy with gemcitabine and S-1 was well tolerated and efficacious for refractory mCRC pts.

301 Background: In the phase III JAVELIN Renal 101 trial (NCT02684006), A + Ax demonstrated significantly longer progression-free survival (PFS) and a higher objective response rate (ORR) vs S in patients with previously untreated aRCC. The role of immune checkpoint + VEGFR inhibition in elderly patients remains unclear. Here we report the efficacy of A + Ax vs S by age group from the second interim analysis (IA) of overall survival (OS) and the safety of A + Ax by age group from the first IA. Methods: Patients were randomized 1:1 to receive A 10 mg/kg intravenously every 2 wk + Ax 5 mg orally twice daily or S 50 mg orally once daily for 4 wk (6-wk cycle). PFS and ORR per independent central review (RECIST 1.1), OS, and safety by age group (<65, ≥65 to <75, and ≥75 y) were assessed. Results: A total of 271/138/33 and 275/128/41 patients in each age group (<65, ≥65 to <75, and ≥75 y, respectively) were randomized to the A + Ax or S arm, respectively. The proportion of IMDC risk groups was generally well balanced between the A + Ax and S arm in each age group, although in the ≥75 y age group, the frequency of patients with intermediate risk was slightly higher in the A + Ax arm, and that of patients with favorable risk was slightly higher in the S arm. The percentages of patients with favorable/intermediate/poor risk in each age group were 19%/61%/19%, 28%/58%/13%, and 12%/76%/12% in the A + Ax arm vs 20%/63%/16%, 23%/60%/16%, and 24%/61%/15% in the S arm. At data cut-off (Jan 2019) for the second IA, median follow-up for OS and PFS was 19.3 vs 19.2 mo and 16.8 vs 15.2 mo for the A + Ax vs S arm, respectively. The table shows OS, PFS, and ORR by age group. In the A + Ax arm, the most common treatment-emergent adverse events (AEs) were diarrhea (62%/68%/42%), hypertension (49%/49%/55%), palmar-plantar erythrodysesthesia syndrome (37%/31%/15%), fatigue (37%/53%/30%), and nausea (34%/37%/21%) in each age group. Grade ≥3 treatment-emergent AEs and immune-related AEs were observed in 69%/74%/73% and 39%/40%/24% of patients in each age group, respectively. Conclusions: A + Ax demonstrated favorable efficacy across age groups, including patients aged ≥75 y. OS was still immature; follow-up for the final analysis is ongoing. The safety profile was generally consistent between age groups. Clinical trial information: NCT02684006 . [Table: see text]

Phase Iii Study

267 Background: Atezo + bev has been approved globally for pts with unresectable HCC who have not received prior systemic therapy, based on results from IMbrave150 (NCT03434379). At a median of 8.6 mo follow-up, both coprimary endpoints were met, with statistically significant and clinically meaningful improvements observed with atezo + bev vs sor for OS (HR, 0.58 [95% CI, 0.42, 0.79]; P<0.001) and independently-assessed progression-free survival (PFS; per RECIST 1.1; HR, 0.59 [95% CI, 0.47, 0.76]; P<0.001) (Finn, et al. N Engl J Med 2020). Here, we report an updated OS analysis for IMbrave150. Methods: The global, multicenter, randomized, open-label, Phase III study IMbrave150 enrolled 501 systemic treatment–naive pts with unresectable HCC, ≥1 measurable untreated lesion (RECIST 1.1), Child-Pugh class A liver function and ECOG PS 0/1. Pts were randomized 2:1 to receive either atezo 1200 mg IV q3w + bev 15 mg/kg IV q3w or sor 400 mg bid until unacceptable toxicity or loss of clinical benefit per investigator. This post hoc, descriptive OS analysis was conducted with 12 mo of additional follow up from the primary analysis. Results: 501 pts were enrolled, including 336 to atezo + bev and 165 to sor. At the clinical cut-off date of Aug 31, 2020, median follow-up was 15.6 mo and 280 OS events were observed. Median OS was 19.2 mo with atezo + bev vs 13.4 mo with sor (HR, 0.66 [95% CI, 0.52, 0.85]; P=0.0009). Survival at 18 mo was 52% with atezo + bev and 40% with sor. Survival benefit with atezo + bev over sor was generally consistent across subgroups and with the primary analysis. The updated objective response rate (ORR; 29.8% per RECIST 1.1) with atezo + bev was in line with the primary analysis, with more pts achieving complete response (CR; 7.7%) than previously reported. Additional response data are in Table. Safety was aligned with the primary analysis, with no new signals identified. Conclusions: IMbrave150 showed consistent clinically meaningful treatment benefit and safety with 12 mo of additional follow-up. The combination provides the longest survival seen in a front-line Phase III study in advanced HCC, confirming atezo + bev as a standard of care for previously untreated, unresectable HCC. Clinical trial information: NCT03434379. [Table: see text]
