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 .

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.

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.

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.

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.

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.

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.

PurposeThis phase III study compared the safety and efficacy of the following three different irinotecan-containing regimens in the first-line treatment of metastatic colorectal cancer: irinotecan plus infusional fluorouracil (FU)/leucovorin (LV) (FOLFIRI), irinotecan plus bolus FU/LV (mIFL), and irinotecan plus oral capecitabine (CapeIRI).Patients and MethodsA total of 430 previously untreated metastatic colorectal cancer patients were randomly assigned to receive FOLFIRI (n = 144), mIFL (n = 141), or CapeIRI (n = 145). Patients were concurrently randomly assigned to a double-blind treatment with celecoxib or placebo. After a protocol amendment, an additional 117 patients were randomly assigned to either FOLFIRI plus bevacizumab (FOLFIRI+Bev; n = 57) or mILF plus bevacizumab (mIFL+Bev; n = 60), whereas the CapeIRI arm was discontinued. The primary study end point was progression-free survival (PFS), with secondary end points of overall survival (OS), response rate, and toxicity.ResultsMedian PFS was 7.6 months for FOLFIRI, 5.9 months for mIFL (P = .004 for the comparison with FOLFIRI), and 5.8 months for CapeIRI (P = .015). Median OS was 23.1 months for FOLFIRI, 17.6 months for mIFL (P = .09), and 18.9 months for CapeIRI (P = .27). CapeIRI was associated with higher rates of severe vomiting, diarrhea, and dehydration. After the amendment to add bevacizumab, the median survival time has not yet been reached for FOLFIRI+Bev and was 19.2 months for mIFL+Bev (P = .007). FOLFIRI+Bev was associated with a higher rate of ≥ grade 3 hypertension than mIFL+Bev.ConclusionFOLFIRI and FOLFIRI+Bev offered superior activity to their comparators and were comparably safe. An infusional schedule of FU should be the preferred irinotecan-based regimen in first-line metastatic colorectal cancer.

242 Background: In the present guidelines for the management of metastatic castration-resistant prostate cancer (CRPC), it is unclear who benefits from androgen receptor axis-targeted agents (ARATs) or docetaxel as a first-line treatment. Methods: We conducted a single-institutional retrospective study to explore treatment-specific biomarkers for treatment response of metastatic CRPC. A cohort of 211 patients with metastatic CRPC treated with either ARAT (abiraterone acetate or enzalutamide) or docetaxel as a first-line treatment was evaluated. In addition to well-established biomarkers such as hemoglobin, neutrophil-to-lymphocyte ratio, alkaline phosphatase, and lactate dehydrogenase, we also assessed red cell distribution width, platelet count, and mean platelet volume (MPV). Laboratory measures were assessed within 1 month before starting treatment. Prostate-specific antigen progression-free survival (PSA-PFS) and radiographic progression-free survival (RPFS) were evaluated. Multivariable Cox regression models were used to assess the association between biomarkers and the risk of events. We also studied the statistical interaction between biomarkers and clinical outcomes. Results: Of all blood-based biomarkers, multivariable Cox regression models identified pre-treatment MPV (≤9.0 fL) as an independent prognostic factor of both PSA progression (hazard ratio [HR]: 2.62, 95% confidence interval [CI]: 1.25-5.48, P = 0.011) and radiographic progression (HR: 4.46, 95% CI: 1.79-11.1, P = 0.001). In addition, these models showed a lower risk of PSA progression (HR: 0.38, 95% CI: 0.15-0.96, P = 0.041) and radiographic progression (HR: 0.16, 95% CI: 0.05-0.50, P = 0.002) with docetaxel compared with ARAT when pre-treatment MPV was small. Conclusions: The present study identified MPV as a significant treatment-specific prognostic factor of PSA progression and radiographic progression in patients with metastatic CRPC treated with a first-line treatment. Furthermore, our results suggested that small MPV was associated with superior survival benefit on docetaxel over ARAT.

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.
