e20583 Background: Current standard of care for SCLC relapsed within six months after first-line treatment was mainly chemotherapy alone, such as irinotecan or docetaxel, of which the clinical benefit is unsatisfactory. Anlotinib, a novel oral multi-target tyrosine kinase inhibitor primarily targeting VEGFR2/3, FGFR1-4, PDGFRα/β and c-Kit, significantly improved progression-free survival (PFS) and overall survival (OS) for SCLC in third-line setting and beyond treatment (ALTER1202 trial). Here, we conducted a single-arm phase II trial to evaluate the efficacy and safety of anlotinib combined with irinotecan or docetaxel in SCLC relapsed within six months after first-line treatment. Methods: Eligible patients with cytologically or histologically confirmed SCLC, aged 18-75 years, ECOG PS 0-1, relapsed within six months after first-line platinum-based treatment, received anlotinib (12mg, QD, from day 1 to 14 of a 21-day cycle) combined with irinotecan (65mg/m2, day1,8, q3w, up to 4 cycles) or docetaxel (60mg/m2, q3w, up to 4 cycles) until disease progression or intolerable toxicity. The primary endpoint was the objective response rate (ORR). Secondary endpoints included PFS, the disease control rate (DCR), OS and safety. Results: Between March 2020 and February 2021, 21 patients with a median age of 61.7 years, male (76.2%), ECOG PS 1 (81.0%), brain metastasis (42.9%), liver metastasis (38.1%), were enrolled in this trial. At data cut-off (February 8, 2021), 15 patients were evaluable, among which 5 patients reached partial response (PR) and 8 had stable disease (SD). The ORR was 33.3% (5/15) and the DCR was 86.7% (13/15), respectively. The median PFS was 4.0 months (95%Cl: 3.18-4.83). The most common grade 1-2 treatment-related adverse events (TRAEs) were weakness (64.7%), anorexia (41.2%), anemia (29.4%), hypertension (23.5%), leukopenia (17.6%), oral mucositis (17.6%). Grade 3 TRAEs mainly included leukopenia (11.8%), thrombocytopenia (11.8%) and anemia (5.9%). There were no grade 4 or higher toxicities. Conclusions: Anlotinib combined with irinotecan or docetaxel showed promising ORR, DCR and PFS in SCLC relapsed within six months after first-line platinum-based treatment and was well-tolerated. No unexpected toxicities were observed. Further exploration and longer follow-up are ongoing. Clinical trial information: NCT04757779.

477 Background: We assessed RAM or MER plus standard of care GEM+CIS as first-line treatment for BTC. Methods: Patients (pts) with BTC, ECOG PS 0/1, and measurable disease were randomized 2:1:2:1 to oral MER 80 mg QD, oral PL QD, IV RAM 8 mg/kg days 1 and 8 Q3W or IV PL days 1 and 8 Q3W. Pts also received up to 8 cycles IV GEM 1000 mg/m2 + CIS 25 mg/m2 days 1 and 8 Q3W. RAM, MER, or PL could continue until disease progression. Primary endpoint: progression-free survival (PFS). Secondary endpoints: overall survival (OS), objective response rate (ORR), and safety. PFS and hazard ratios (HRs) were compared using stratified log-rank tests and Cox regression models, respectively. NCT02711553. Results: 309 pts were randomized to RAM (106), MER (102), or pooled PL (101). More pts in the RAM (54.7%) and MER (49.0%) groups had baseline ECOG PS 1 vs PL (38.6%). Efficacy endpoints are in Table. Fewer pts received post-discontinuation systemic therapy in the RAM group (RAM 37.5%, MER 50.0%, PL 52.0%). The most common grade ≥3 treatment-emergent adverse events were: RAM vs PL: neutropenia (49.0% vs 33.0%), thrombocytopenia (34.6% vs 17.0%), and anemia (26.9% vs 19.0%); MER vs PL: neutropenia (47.1% vs 33.0%), thrombocytopenia (18.6% vs 17.0%), and alanine aminotransferase increased (10.8% vs 5.0%). Conclusions: PFS, OS, and ORR were not improved with the addition of RAM or MER to GEM+CIS. Treatment was well tolerated, with safety profiles consistent with known profiles for RAM, MER, and GEM+CIS. Translational studies are ongoing. Clinical trial information: NCT02711553 .

e21040 Background: The anti-angiogenic drug bevacizumab combined with chemotherapy has achieved positive results in previous studies. In particular, the median progression-free survival (PFS) for EGFR-negative patients was increased to 8.3 months in the BEYOND study. Unlike bevacizumab, anlotinib is a novel multitarget tyrosine kinase inhibitor and can be conveniently orally administered. In the phase III trial ALTER 0303, anlotinib significantly improved overall survival (OS) and PFS in advanced NSCLC patients. This exploratory study aims to establish the efficacy and safety of anlotinib in combination with pemetrexed and carboplatin as first-line treatment in advanced non-squamous NSCLC. Methods: This is a multi-center, single-arm clinical trial. Adults with treatment-naive, histologically confirmed stage IIIB-IV non-squamous NSCLC, ECOG 0-1, and without known sensitizing EGFR/ALK alterations are included. Patients received anlotinib (12 mg p.o., QD, d1 to 14, 21 days per cycle) combined with pemetrexed (500 mg/m2, iv, d15-21, Q3W) + carboplatin (AUC = 5, iv, d15-21, Q3W) for 4 cycles followed by anlotinib and pemetrexed maintenance until disease progression (PD). The primary endpoint was PFS. Secondary endpoints were OS, objective response rate (ORR), disease control rate (DCR) and safety. Results: Between Mar 2019 and Dec 2020, 40 patients were enrolled in six centers and 31 of them have received at least one tumor assessment. Median age was 62 (33, 75); 66.7% male, 11.1% brain metastasis. At data cutoff (Dec 31, 2020), patients were followed up for a median of 8.26 months. Median PFS was 10.5 months (95% CI: NE, NE); ORR was 67.7% (0 CR, 21 PR), DCR was 96.8% (0 CR, 21 PR, 9 SD) and median OS was NE. The most common Grade ≥ 3 AEs were hypertension 22.2%, neutropenia 19.44%, myelosuppression 11.1%, thrombocytopenia 8.33%, leukopenia 5.56%, hand-foot syndrome 5.56% and there were no Grade 5 toxicities. Conclusions: This study finds that anlotinib plus pemetrexed and carboplatin can significantly improve PFS and ORR compared to standard chemotherapy for treatment-naive non-squamous NSCLC patients. The combination was well tolerated, and the AEs were manageable. The follow-up time is not sufficient, and the OS outcomes need further evaluation. Clinical trial information: NCT03790228.

e19054 Background: The addition of BV to cytotoxic agent(s) prolonged survival for non-Sq NSCLC patients (pts). However, there is no definitive evidence for the cytotoxic agent(s) plus BV is superior to the cytotoxic agent(s) alone for elderly non-Sq NSCLC. We conducted the feasibility study of PEM plus BV as the first-line treatment for elderly advanced or recurrent non-Sq NSCLC. Methods: Major eligibility and exclusion criteria were followings; chemotherapy-naïve; unfit for bolus combination chemotherapy; stage III/IV or relapsed non-Sq NSCLC; age≥70; PS 0-1; no evidence of brain metastasis; no history of hemoptysis and irradiation for thorax. PEM (500 mg/m2) and BV (15 mg/kg) were administrated intravenously on day 1 every 3 weeks. The primary endpoint was toxicity and the secondary endpoints were objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and the percentage of pts who completed more than 3 cycles. Results: From November 2010 to April 2012, total 12 pts were enrolled. Patients characteristics were following; male/female=6/6; Median age (range) 78 (72-81); histology was all adenocarcinoma; activating EGFR mutation no/yes/unknown=9/2/1; stage IIIB/IV/recurrence=2/8/2; ECOG PS 0/1=6/6; smoking history yes/no=6/6. Severe toxicities (Grade 3≥) were leukopenia (25%), neutropenia (25%), anemia (8%), thrombocytopenia (8%), febrile neutropenia (8%), anorexia (8%), hypertension (8%), fatigue (8%), nausea (8%), and perforation (colon) (8%). No dose-limiting toxicity and treatment-related death was occurred. Three patients achieved PR and the ORR was 25%. The median PFS and OS were 5.6 months (mo) (95% C.I. 1.1-7.9 mo) and 10.3 mo (95% C.I. 6.9-15.6 mo) in 11 evaluated pts, respectively. The 1-year survival rate was 49% (95% C.I. 12-79%). Seven of 12 pts (58%) received more than 3 cycles. Conclusions: PEM plus BV as first-line treatment for elderly non-Sq NSCLC was well tolerable and promising.

Background: High tumor mutational burden (TMB-H) has been reported as a predictive marker to immunotherapy or prognostic marker in various tumor types. However, there has been little study of the role of TMB-H in advanced biliary tract cancer (BTC). Methods: We analyzed 119 advanced BTC patients who received Gemcitabine/Cisplatin (GP) as a first-line treatment between November 2019 and April 2021. Next-generation sequencing (NGS), including TMB analysis, as a routine clinical practice was performed in 119 patients. The TruSightTM Oncology 500 assay from Illumina was used as a cancer panel. Results: Among 119 patients, 18 (18.5%) had a tumor with high TMB (≥ 10 Muts/Mb). There were no significant differences between the status of TMB and clinical outcomes with GP, including objective response rate (ORR) ( P = .126), disease control rate (DCR) ( p = .454), and median progression-free survival (PFS) ( p = .599). The median overall survival (OS) was not different between patients with TMB-H and no TMB-H ( p = .430). In subgroup analysis of 32 patients receiving immune checkpoint inhibitor (ICIs), there were significant differences in ORR ( p = .034) and median PFS ( p  = .025) with ICIs between patients with and without TMB-H. Conclusions: This study revealed that TMB-H in advanced BTCs did not have a prognostic or role in the standard first-line treatment. However, TMB-H might be a predictive biomarker for response to ICIs in advanced BTC.

5024 Background: In a randomized phase III trial of patients (pts) with mRCC, sunitinib demonstrated a significant improvement in progression-free survival (PFS) and objective response rate (ORR) compared to IFN-a as first-line therapy (Proc ASCO 2006;24:2s [Abstract LBA3]). We present the most recent data from this trial and an analysis of prognostic factors. Methods: Untreated pts with clear-cell mRCC were randomized 1:1 to receive either sunitinib (repeated 6-week cycles of 50 mg/day orally for 4 weeks, followed by 2 weeks off treatment) or IFN-a (9 MU given subcutaneously three times weekly). The primary endpoint was PFS. Results: A total of 750 pts were randomized: 375 to sunitinib, 375 to IFN-a. The median duration of treatment is 11 months (range: <1–25) for sunitinib vs. 4 months (range: <1–22) for IFN-a. The updated ORR by investigator assessment is 44% (95% CI: 39, 49) for sunitinib vs. 11% (95% CI: 8, 15) for IFN-a (p <0.000001), including 4 complete responses for sunitinib and 2 for IFN-a. The median duration of response in the sunitinib group (n=165) is 12 months (95% CI: 10, 14) vs. 10 months (95% CI: 8, 17) in the IFN-a group (n=43). The median PFS is 11 months (95% CI: 10, 11) for sunitinib vs. 4 months (95% CI: 4, 5) for IFN-a. The median PFS for pts with 0 risk factors is 14 months (95% CI: 11, 16) for sunitinib vs. 8 months (95% CI: 7, 10) for IFN-a; 9 months (95% CI: 8, 11) vs. 4 months (95% CI: 4, 4), respectively, for pts with 1- 2 risk factors; 4 months (95% CI: 2, 10) vs. 1 month (95% CI: 1, 2), respectively, for pts with =3 risk factors. The sunitinib benefit in PFS extends across all MSKCC prognostic risk factor groups (HR=0.488; 95% CI: 0.406, 0.586). The baseline features that predict longer PFS (by investigator assessment) for the sunitinib group are hemoglobin =LLN (p=0.0043), corrected calcium =10 mg/dL (p=0.001), ECOG score of 0 (p=0.0005), number of metastatic sites 0 or 1 (p=0.0064), and time from diagnosis to treatment =1 yr (p=0.0002). Conclusions: Sunitinib is a reference standard for first-line treatment of mRCC, with significant improvement in PFS and ORR compared to IFN-a. The benefit of sunitinib extends across all subgroups of pts with mRCC. Previously defined MSKCC risk factors for mRCC predict longer PFS with sunitinib. No significant financial relationships to disclose.

TPS4696^ Background: Docetaxel (D) in combination with prednisone (P) as first-line (1L) chemotherapy in patients (pts) with mCRPC is the current standard of care. However, treatment is not curative and D-resistant disease typically develops. Cabazitaxel (Cbz) is a novel taxane active in D-sensitive and -resistant tumor models. Clinical activity of Cbz plus P (CbzP) was demonstrated in the Phase III TROPIC study in mCRPC pts previously treated with a D-containing regimen; CbzP showed a significant overall survival (OS) benefit vs mitoxantrone plus prednisone (median OS 15.1 vs 12.7 months; HR 0.70; P < 0.0001). Therefore, it is of interest to determine if CbzP provides an OS advantage vs DP in 1L mCRPC pts. Methods: The phase III FIRSTANA study (NCT01308567) is a randomized, open-label, multinational trial in 1L mCRPC pts, designed to compare the efficacy of Cbz 25 mg/m² IV Q3W (Arm A) and Cbz 20 mg/m² IV Q3W (Arm B) vs D 75 mg/m2 IV Q3W (Arm C). P 10 mg PO QD is to be given concomitantly. Pts are stratified by ECOG PS (0–1 vs 2), measurable disease (yes/no) and region (depending on availability of Cbz as 2L). Pts with ECOG PS ≤ 2, histologically/cytologically confirmed metastatic prostate adenocarcinoma, with no prior chemotherapy and with disease progression following medical or surgical castration are eligible. The primary endpoint is OS. Secondary endpoints include progression-free survival (PFS) (PCWG2 criteria), radiologic PFS, tumor response in measurable disease (RECIST 1.1), PSA response and PSA PFS, pain response and pain PFS, time to occurrence of any skeletal-related events, safety profile and health-related quality of life. Cbz pharmacokinetics and pharmacogenomics will be assessed in pt subgroups. Pts will be treated until progression, unacceptable toxicity or pt request. Planned enrollment is 1,170 pts; study size was calculated to achieve 90% power for OS. Study start was in May 2011; at January 2012, 219 pts were enrolled. The first DMC meeting recommended continuing the study without change.

335 Background: Perioperative cisplatin based chemotherapy (PCBC) is a standard of care in the management of muscle invasive urothelial carcinoma (UC). Cisplatin based (C) therapy also represents the historical first line treatment of metastatic disease. There is however no data to guide the optimal choice of first line chemotherapy regimen – C re-treatment vs other second-line or non cisplatin regimens (NC) –in UC patients who relapse after receiving PCBC. This multicenter retrospective study compares C vs NC first line treatment on progression-free survival (PFS) for patients (pts) with advanced UC after PCBC and cystectomy. Methods: Data were collected for patients who received various first-line chemotherapies for advanced UC following previous PCBC therapy. Cox proportional hazards models were used to investigate the prognostic ability of type of peri-operative / first-line chemotherapy, visceral metastasis, ECOG status, time from prior chemotherapy (TFPC), anemia, leukocytosis and albumin on PFS. Results: Data were available for 145 pts from 12 centers. The mean age was 62 years, 113 (77.9%) were men and ECOG-PS was 0 or >0 in 74 (51.0%) and 61 (42.0%) patients. Ninety-one (62.8%) pts received C first line, the median number of cycles was 4 (range 1-17) and the median TFPC was 6.2 months (range 1-154). Median overall survival was 86 weeks (95% CI 70-106) and median PFS was 24 (95% CI 18-27) weeks. Time from perioperative chemotherapy (TFPC) (>52 weeks vs ≤52 weeks; HR 0.63 p=0.027) and ECOG-PS at first line (1+ vs 0; HR 1.73 p=0.010), were prognostic of PFS. No significant effect was noted for C vs NC first line (p=0.70); however, among patients with TFPC >52 weeks, patients with NC had worse PFS (median 4.6 months, 95% CI 1.8-12.2) than those who received C (median 8.1, 95% CI 3.2-16.3). Conclusions: There is no evidence to suggest overall superiority of C vs NC based first line chemotherapy or a second-line regimen in patients with advanced UC who received prior PCBC. However, those with TFPC >52 weeks should probably receive C first line chemotherapy given better PFS with C.

e15018 Background: Controversy surrounds the question of whether the prognosis of most patients with metastatic colorectal cancer (mCRC) is improved using intensive administration of folinic acid, 5-fluorouracil, oxaliplatin and irinotecan (FOLFOXIRI) alone or combined with target therapy as first-line treatment. Methods: We queried PubMed, the Cochrane Collaboration Central Register of Controlled Clinical Trials, Cochrane Systematic Reviews, ClinicalTrials.gov, the databases of the European Society for Medical Oncology and the American Society of Clinical Oncology to identify abstracts of randomized controlled trials evaluating the efficacies and toxicities of intensive therapies used for first-line treatment of patients with mCRC. The search included articles dated from the inception of these resources until December 31, 2016. We estimated hazard ratios (HRs) for overall survival (OS) and progression-free survival (PFS) and relative risks (RRs) for the objective response rate (ORR), the R0 resection rate, and toxicities. Results: Nine RCTs comprising 2,256 patients were included in this network meta-analysis. The PFS of patients administered FOLFOXIRI plus target therapy experienced prolonged PFS and OS and improved ORRs compared with FOLFOX or FOLFIRI plus target therapy (PFS: HR 0.65, 95% CI 0.46–0.91; OS: HR 0.80, 95% CI 0.65–0.98; ORR: HR 1.70, 95% CI 1.16–2.49; R0 resection rate: HR 2.66, 95% CI 1.86–3.82). There were no significant differences between PFS, OS, ORRs, or R0 resection rates and toxicities of patients administered FOLFOXIRI and FOLFOX or FOLFIRI plus target therapy. Further, FOLFOXIRI plus target therapy did not increase toxicities compared with FOLFOX or FOLFIRI plus target therapy, except for neutropenia. Conclusions: FOLFOXIRI plus target therapy when administered as first-line treatment of patients with mCRC is the best choice and did not significantly increase toxicities. FOLFOXIRI is as effective as FOLFOX or FOLFIRI plus target therapy.

710 Background: SBP-101, a polyamine metabolic inhibitor, inhibited growth in 6 human pancreatic ductal adenocarcinoma (PDA) cell lines and 3 murine xenograft tumor models of human PDA. SBP-101 monotherapy in heavily pre-treated PDA patients (> 2 prior regimens, N=4) showed a median survival of 5.9 months at the optimal dose level. Purpose: To assess the safety, tolerability, PK, and efficacy of SBP-101 in combination with gemcitabine (G) and nab-paclitaxel (A) in patients with previously untreated metastatic PDA. Methods: In a modified 3+3 dose escalation scheme, subcutaneous injections of SBP-101 were dosed at 0.2, 0.4 or 0.6 mg/kg days 1-5 of each 28-day cycle. G (1000 mg/m2) and A (125 mg/m2) were administered intravenously on Days 1, 8, and 15 of each cycle. Safety and tolerability were evaluated by clinical and laboratory assessments. PK was evaluated on day 1 of cycle 1. Efficacy was assessed by CA19-9 levels, objective response as assessed by RECIST criteria, progression-free survival (PFS) and overall survival (OS). Results: Fifteen patients have been enrolled in 3 cohorts (1: N=4, 2: N=7, 3: N=4) and received up to 6 cycles of treatment (7 subjects are ongoing in cohorts 2 and 3). The most common adverse events related to SBP-101 are fatigue (N=4), nausea (N=2) and injection site pain (N=2). There is no evidence of SBP-101-related bone marrow suppression or peripheral neuropathy. One patient in cohort 2 developed grade 3-4 reversible liver enzyme elevation. PK parameters in cohort 1 were below the limits of detection at most time points, but plasma Cmax and AUC0-t were measurable in cohorts 2 and 3. In those cohorts, CA19-9 levels decreased 76-95% in 7 of 8 evaluable subjects (1 additional subject TBD), with 5 patients achieving partial responses (4 ongoing) and 1 achieving stable disease. Median PFS and OS have not yet been reached. Conclusions: Preliminary results suggest SBP-101 is well tolerated when administered with G and A. Signals of efficacy support continued development of SBP-101 in combination first-line treatment for PDA. Clinical trial information: NCT03412799.

RAISE: A randomized, double-blind, multicenter phase III study of irinotecan, folinic acid, and 5-fluorouracil (FOLFIRI) plus ramucirumab (RAM) or placebo (PBO) in patients (pts) with metastatic colorectal carcinoma (CRC) progressive during or following first-line combination therapy with bevacizumab (bev), oxaliplatin (ox), and a fluoropyrimidine (fp).

512 Background: Angiogenesis is an important therapeutic target in CRC; VEGF plays a key role in angiogenesis. RAM is a human IgG1 monoclonal antibody that targets the extracellular domain of VEGFR-2. The RAISE study evaluated the efficacy and safety of adding RAM to standard second-line treatment FOLFIRI. Methods: Eligible pts with mCRC who progressed on or after first-line combination therapy with bev, ox, and fp, had an ECOG PS of 0 or 1, and adequate organ function were randomized 1:1 (stratified by region, KRAS mutation status, and time to progressive disease [PD] after beginning first-line treatment) to receive RAM (8 mg/kg IV) plus FOLFIRI or PBO plus FOLFIRI every 2 weeks until PD, unacceptable toxicity, or death. The primary endpoint was overall survival (OS). Secondary endpoints included progression-free survival (PFS), objective response rate (ORR), and safety. Planned sample size of 1,050 pts ensured 85% power to demonstrate statistical significance at an overall two-sided alpha of 0.05, assuming a hazard ratio (HR) of 0.8. Results: Between Dec 2010 and Aug 2013, 1,072 eligible pts were randomized (RAM 536; PBO 536). Baseline pt characteristics were similar between treatment arms. The OS HR was 0.84 (95% CI: 0.73, 0.98; log-rank p=0.0219). Median OS was 13.3months (m) for RAM vs 11.7m for PBO. The PFS HR was 0.79 (95% CI: 0.70, 0.90; log-rank p = 0.0005). Median PFS with RAM was 5.7m and 4.5m for PBO. ORR was 13.4% RAM; 12.5% PBO (p = 0.6336). Subgroup results were consistent with the OS and PFS results. Grade ≥3 adverse events (AEs) occurring in >5% of pts in RAM+FOLFIRI were: neutropenia (RAM 38.4% vs PBO 23.3% ), hypertension (11.2% vs 2.8%), diarrhea (10.8% vs 9.7%), and fatigue (11.5% vs 7.8%). Conclusions: RAISE met its primary end-point, demonstrating a statistically significant improvement in OS for RAM and FOLFIRI vs PBO and FOLFIRI in second-line mCRC pts. Benefits were similar across important clinical subgroups and no unexpected AEs were identified. Clinical trial information: NCT01183780.
