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.

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.

e20527 Background:Platinum-based chemotherapy is the standard first-line treatment for non-squamous NSCLC patients without driver oncogene (EGFR, KRAS, and ALK mutations). However, it remains unknown that from which chemotherapy regimens can those patients get more benefit. Therefore, the study explore whether pemetrexed combined with platinum chemotherapy is superior to the other platinum-based chemotherapy regimens.Methods:We performed a retrospective study on 114 histologically or cytologically advanced IIIB-IV NSCLC patients admitted to Cancer Hospital from 1 Jan 2013 to 30 Dec 2015. The primary endpoint was the median progression free survival (PFS) and the disease control rate (DCR). And objective response was evaluated every two cycles by imaging according to the Response Evaluation Criteria In Solid Tumors (RECIST version 1.0). The multivariate logistic analyses were carried out by SPSS version 16.0. Results:114 patients received platinum-base doublet as first-line treatment. Among them, 59 patients underwent pemetrexed-containing regimens, and 55 patients received non-pemetrexed-containing regimens (38 patients for paclitaxel-containing regimens, 13 patients for gemcitabine-containing regimens, and 4 patients for other regimens.). The baseline characteristics between two groups were comparable ( p>0.05). The median PFS of pemetrexed-containing regimens was significantly longer compared with that of non-pemetrexed-containing regimens (7.2 months [95% CI: 5.3–9.1] vs. 4.9 months [95% CI: 3.2–6.6], p%0.05). DCR of pemetrexed-containing regimens was better than that of non-pemetrexed-containing regimens in the multivariate logistic analysis (89.8% vs.74.5%, p%0.05).Conclusions:Pemetrexed-containing regimens displayed more benefit than the other chemotherapy regimens for non-squamous NSCLC patients without driver oncogene. However, large scale perspective study is warranted in the future.

LBA7500 Background: Afatinib (A) is a selective, orally bioavailable, irreversible ErbB family blocker of EGFR (ErbB1), HER2 (ErbB2), and ErbB4. This global study investigated the efficacy and safety of A compared with pemetrexed/cisplatin (PC) in pts with EGFR mutation positive advanced lung adenocarcinoma. Methods: Following central testing for EGFR mutations (companion diagnostic TheraScreen EGFR RGQ PCR kit), 345 pts (stage IIIB/IV, PS 0–1, chemo-naive) were randomized 2:1 (A: 230; PC: 115) to daily A 40 mg or iv PC (500 mg/m2 + 75 mg/m2 q21 days up to 6 cycles). Primary endpoint was progression-free survival (PFS) by central independent review. Results: Baseline characteristics were balanced in both arms: median age, 61 y; female, 65%; Asian, 72%; never-smoker, 68%; Del19, 49%; L858R, 40%; other mutations, 11%. Treatment with A led to a significantly prolonged PFS vs PC (median 11.1 vs 6.9 mos; HR 0.58 [0.43–0.78]; p=0.0004). In 308 pts with common mutations (Del19/L858R), median PFS was 13.6 vs 6.9 mos, respectively (HR=0.47 [0.34–0.65]; p<0.0001). Objective response rate was significantly higher with A (56% vs 23%; p<0.0001). Significant delay in time to deterioration of cancer-related symptoms of cough (HR=0.60, p=0.0072) and dyspnea (HR=0.68, p=0.0145) was seen with A vs PC. Most common drug-related adverse events (AEs) were diarrhea (95%), rash (62%) and paronychia (57%) with A, and nausea (66%), decreased appetite (53%) and vomiting (42%) with PC. Drug-related AEs led to discontinuation in 8% (A; 1% due to diarrhea) and 12% of pts (PC). Conclusions: LUX-Lung 3 is the largest prospective trial in EGFR mutation positive lung cancer and the first study using pemetrexed/cisplatin as a comparator. Treatment with afatinib significantly prolonged PFS compared to PC, with significant improvements in secondary endpoints. AEs with afatinib were manageable, with a low discontinuation rate. With 4.2 mos PFS improvement in the overall population and 6.7 mos in pts with common mutations, afatinib is a clinically relevant first-line treatment option.

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.

PURPOSE: To study how adding oxaliplatin (l-OHP) to chronomodulated fluorouracil (5-FU)–leucovorin (LV) affected the objective response rate, as first-line treatment of metastatic colorectal cancer. PATIENTS AND METHODS: Two hundred patients from 15 institutions in four countries were randomly assigned to receive a 5-day course of chronomodulated 5-FU and LV (700 and 300 mg/m2/d, respectively; peak delivery rate at 0400 hours) with or without l-OHP on the first day of each course (125 mg/m2, as a 6-hour infusion). Each course was repeated every 21 days. Response was assessed by extramural review of computed tomography scans. RESULTS: Grade 3 to 4 toxicity from 5-FU–LV occurred in ≤ 5% of the patients (≤ 1% of the courses). Grade 3 to 4 diarrhea occurred in 43% of the patients given l-OHP (10% of the courses), and less than 2% of the patients had severe hematotoxicity. Thirteen percent of the patients had moderate functional impairment from peripheral sensory neuropathy. Sixteen percent of the patients receiving 5-FU–LV had an objective response (95% confidence interval [CI], 9% to 24%), compared with 53% of those receiving additional l-OHP (95% CI, 42% to 63%) (P < .001). The median progression-free survival time was 6.1 months with 5-FU–LV (range, 4.1 to 7.4 months) and 8.7 months (7.4 to 9.2 months) with l-OHP and 5-FU–LV (P = .048). Median survival times were 19.9 and 19.4 months, respectively. CONCLUSION: By chronomodulating 5-FU–LV, we were able to add l-OHP without compromising dose-intensities. l-OHP significantly improved the antitumor efficacy of this regimen.

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.

e15550 Background: The combination of anti-VEGF or anti-EGFR targeted drugs with chemotherapy is the standard first-line therapy for metastatic colorectal cancer (mCRC), and the followed maintenance treatment is an optional approach to balance the efficacy and toxicity. However, studies regarding the maintenance strategies based on antiangiogenic TKIs are limited currently. Anlotinib, a novel oral multi-target TKI which can inhibit both tumor angiogenesis and tumor cell proliferation simultaneously, substantially prolonged the PFS with manageable toxicity for refractory mCRC in the phase III ALTER0703 clinical trial. Here we report an update on the effectiveness and safety of anlotinib plus XELOX as first-line treatment followed by anlotinib monotherapy for mCRC. Methods: In this open label, single-arm, multicenter phase II clinical trial, 53 mCRC patients without prior systemic treated, aged 18-75 and an ECOG performance status of 0 or 1 were planned to recruit. Eligible patients received capecitabine (1000 mg/m2, po, d1-14, q3w) and oxaliplatin (130 mg/m2, iv, d1, q3w) plus anlotinib (10mg, po, d1̃14, q3w) treatment for 6 cycles. After 6 cycles of inducing therapy, patients would receive anlotinib (12mg, po, d1̃14, q3w) as maintenance therapy until disease progression or intolerable adverse events (AEs). The primary endpoint was PFS; Secondary endpoints included ORR, DCR, DOR and safety. Results: By the data analysis cutoff date of January 22, 2021, a total of 18 patients were enrolled, of which 12 patients were available for efficacy assessment. In best overall response assessment, there were 50.0% PR (6/12), 33.3% SD (4/12) and 16.7% PD (2/12). The ORR was 50.0% (95% CI, 21.1-78.9%) and DCR was 83.3% (95% CI, 51.5-97.9%). The longest duration of treatment was 8.8 months and the response was still ongoing. The median PFS was not reached. The most common treatment related adverse events (TRAEs) of any grade (≥20%) were leukopenia, hypertension, neutropenia, diarrhea, fatigue, hypertriglyceridemia. Grade 3/4 TRAEs included hypertension (22.2%), hypertriglyceridemia (11.1%), lipase elevated (11.1%) and neutropenia (5.6%). No grade 5 AEs occurred. Conclusions: The update results suggested that anlotinib combined with XELOX as first line regimen followed by anlotinib monotherapy showed promising anti-tumor activity and manageable safety for patients with mCRC. And the conclusions needed to be confirmed in trials continued subsequently. Clinical trial information: ChiCTR1900028417.

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.
