TPS260 Background: Deficient DNA mismatch repair (dMMR) colorectal cancer (CRC) is highly immunogenic. Preclinical data showed synergistic interactions among FOLFOX, anti-VEGF, and programmed cell death-1 (PD-1) pathway blockade. Prior phase I study of mFOLFOX6/ bevacizumab (bev) + atezolizumab (atezo) was well tolerated and enhanced intratumoral infiltration of CD8+ T cells. We hypothesize that the dMMR subset of CRC may be effectively targeted with combination of PD-1 pathway blockade and mFOLFOX6/bev. Methods: This is a prospective randomized phase III open-label trial. Pts (N=347) with mCRC dMMR will be randomized to three trial arms (1:1:1): mFOLFOX6/bev; atezo monotherapy; or mFOLFOX6/bev + atezo. Stratification factors include BRAFV600E status, metastatic site, and prior adjuvant CRC therapy. Primary endpoint is progression-free survival (PFS) assessed by study investigator of mFOLFOX6/bev/atezo and atezo monotherapy compared to mFOLFOX6/bev. Secondary endpoints include OS, objective response rate, safety profile, disease control rate, duration of response, and PFS by retrospective central review. Health-related quality of life is an exploratory objective. Archived tumor tissue and blood samples will be collected for correlative studies. Key inclusion criteria are: mCRC without prior chemotherapy for advanced disease; dMMR tumor determined by local CLIA-certified IHC assay (MLH1/MSH2/MSH6/PMS2); availability of archived tumor tissue for central confirmation of dMMR status; and measurable disease per RECIST. Activated 11-7-17. As of 9-11-19, enrollment continues with 44/347 pts enrolled. Clinical trial: NCT02997228. Support:U10CA180868, -180822, -180888, -180819, UG1CA189867, U24CA196067; Genentech, Inc.

TPS728 Background: Deficient DNA mismatch repair (dMMR) colorectal cancer (CRC) cells are highly immunogenic. Preclinical data showed that oxaliplatin-containing chemotherapy combined with anti-VEGF enhances antitumor activity of programmed cell death-1 (PD-1) pathway blockade in murine CRC models. Prior phase I study showed mFOLFOX6/ bevacizumab (bev) + atezolizumab (atezo) was well tolerated and enhanced intratumoral infiltration of CD8+ T cells. We hypothesize that the dMMR subset of CRC may be effectively targeted with combination of PD-1 pathway blockade and mFOLFOX6/bev to promote tumor regression. Methods: This is a prospective randomized phase III open-label trial. Pts (N=347) with mCRC dMMR will be randomized to 3 trial arms (1:1:1): mFOLFOX6/bev; atezo monotherapy; or mFOLFOX6/bev + atezo. Stratification factors include BRAFV600E status, metastatic site, and prior adjuvant CRC therapy. Primary objective is to evaluate efficacy of mFOLFOX6/bev/atezo and atezo monotherapy compared to mFOLFOX6/bev. Primary endpoint is progression-free survival (PFS) assessed by study investigator. Secondary endpoints include overall survival, objective response rate, safety profile, surgical conversion rate, disease control rate, duration of response, and PFS by retrospective central review. Health-related quality of life is an exploratory objective. Archived tumor tissue and blood samples will be collected for correlative studies. Key inclusion criteria are: mCRC without prior chemotherapy for advanced disease; tumor determined to be dMMR by local CLIA-certified IHC assay (MLH1/MSH2/MSH6/PMS2); availability of archived tumor tissue for central confirmation of dMMR status; and measurable disease per RECIST. Activated 11-7-17. As of 9-24-18, 13/347 pts have been enrolled. Clinical trial: NCT02997228. Support: U10CA180868, -180822, -180888, -180819, UG1CA189867, U24CA196067; and Genentech, Inc.

TPS3618 Background: The superiority of inhibition of programmed cell death-1 (PD-1) pathway in dMMR/MSI-H over chemotherapy with either anti-vascular endothelial growth factor receptor (VEGFr) or anti- epithelial growth factor receptor (EGFr) antibodies in mCRC has been demonstrated in a phase III trial (N Engl J Med 2020; 383:2207). However, more patients had progressive disease as the best response in the anti-PD1 monotherapy arm (29.4% vs. 12.3%) with mean progression-free survival (PFS) of 13.7 months. Preclinical models have demonstrated synergistic interactions between FOLFOX, anti-VEGF, and anti-PD-1. We hypothesize that the dMMR/MSI-H mCRC patients may be more effectively treated by the combination of PD-1 pathway blockade and mFOLFOX6/bevacizumab (bev) rather than with anti-PD-L1 therapy (atezo) alone. Methods: Initially a three-arm study, the mFOLFOX6/bev arm was closed to new enrollment on 6-4-20 due to emerging data; the redesigned COMMIT trial was reactivated on 1/29/2021 as a prospective phase III open-label trial that randomizes (1:1) mCRC dMMR/MSI-H pts (N=211) to either atezo monotherapy or mFOLFOX6/bev+atezo combination. Stratification factors include BRAFV600E status, metastatic site, and prior adjuvant CRC therapy. Primary endpoint is PFS as assessed by site investigator. Secondary endpoints include overall survival (OS), objective response rate (RECIST v1.1), safety profile, disease control rate, duration of response, and centrally-reviewed PFS. Health-related quality of life is an exploratory objective. Archived tumor tissue and blood samples will be collected for correlative studies. Key inclusion criteria are: mCRC without prior chemotherapy for advanced disease; dMMR tumor determined by local CLIA-certified IHC assay (MLH1/MSH2/MSH6/PMS2) or MSI-H by local CLIA-certified PCR or NGS panel; and measurable disease per RECIST.

TPS158 Background: Despite activity of programmed cell death-1 (PD-1) pathway inhibition in dMMR/MSI-H mCRC, approximately one-third of patients demonstrate progressive disease as best response to anti-PD1 monotherapy. Preclinical models have demonstrated synergistic interactions between FOLFOX, anti-VEGF, and anti-PD-1. We hypothesize that the dMMR/MSI-H mCRC subset may be more effectively targeted by the combination of PD-1 pathway blockade and mFOLFOX6/bevacizumab (bev) rather than with anti-PD-1 therapy (atezo) alone.

6028 Background: Cisplatin plus fluorouracil (PF) is main therapy for metastatic nasopharyngeal carcinoma (NPC). However, the efficacy is not satisfactory, especially in patients with metastasis after radical radiotherapy. The purpose of this study was to investigate the efficacy and toxicity of Nimotuzumab combined with PF in patients with metastatic NPC after radical radiotherapy. Methods: Patients with untreated metastatic NPC after radical radiotherapy were recruited from 9 hospitals in China with Simon’s two-stage design. All patients received Nimotuzumab (200mg/w) and cisplatin (100mg/m2, day 1) plus fluorouracil (4g/m², day 1-4) every 3 weeks until progressive disease (PD) or unacceptable toxicity or a maximum of 6 cycles. If patients had still not progressed at this stage, Nimotuzumab (200mg/w) as monotherapy would be delivered until PD. This study was registered in ClinicalTrials.gov, Number NCT01616849. Results: Between Jun, 2012 and April, 2015, 35 patients were enrolled (Table). The objective response rate (ORR) and disease control rate (DCR) were 71.4% and 85.7%, and the median time of progression free survival (PFS) and overall survival (OS) were 6.97 and 11.01 months. The most common toxicities were leukopenia (94.1%), vomiting (97.1%) and nausea (97.1%); the grade 3/4 toxicities were leukopenia (62.9%) and mucositis (20.0%). There was only 1 patient have mild hypotension which related to Nimotuzumab. The ORR, DCR, median time of PFS and OS were 88.9%, 100.0%, 7.29 and 11.47 months in patients who received a total dose of Nimotuzumab ≥ 2400mg, respectively. Conclusions: Nimotuzumab combined with PF has achieved encouraging efficacy with an acceptable safety profile in metastatic NPC after radical radiotherapy. A phase III randomised study is needed. Clinical trial information: NCT01616849. [Table: see text]

TPS3618 Background: Both anti-EGFR and anti-VEGF therapies have shown clinical benefit when they are added in first and second-line in L-sided CRC. The conflicting results in anti-VEGF vs. anti-EGFR studies (FIRE-3, PEAK and CALGB/SWOG 80405 studies) suggest that the sequence of targeted therapies added to FOLFOX or FOLFIRI regimens in first- and second-line treatment could be an important factor in the overall survival (OS) of mCRC patients. Currently, there are no randomized data on the sequential use of an anti-EGFR followed by an anti-VEGF or vice versa. Therefore, the aim of this randomized clinical trial is to compare the efficacy of two treatment sequences, panitumumab followed by bevacizumab versus bevacizumab followed by panitumumab in combination with FOLFOX chemotherapy in first-line and with FOLFIRI in second-line in patients with wild-type RAS, primary L-sided, metastatic colorectal cancer (mCRC). Methods: A phase III, multicentre, open-label and randomized two-arm clinical trial. Untreated patients with wild-type RAS mCRC (determined locally), primary L-sided and unresectable will be screened for this trial. Eligible patients will be randomized 1:1 to receive first-line (1L) panitumumab plus FOLFOX and then bevacizumab plus FOLFIRI as second-line (2L) treatment (Seq. 1) or bevacizumab plus FOLFOX as 1L and then panitumumab plus FOLFIRI as 2L treatment (Seq. 2). Randomization will be stratified by number of metastatic organs involved (1 vs > 1). Primary objective is the comparison of the progression free survival (PFS) rate at 35 months (m) of Seq 1 vs Seq. 2. Secondary objectives: PFS from randomization to 2nd progression or death, OS rate at 35 months and OS of Seq. 1 vs Seq. 2; PFS, objective response rate, disease control rate, early tumour shrinkage, Depth of Response, duration and time to response and safety in 1L treatment and in 2L treatment in each Sequence arm. Exploratory objectives: impact of baseline biomarkers predictive of the efficacy in each Sequence arm and the clinical impact of clonal dynamics by longitudinal analysis of circulating tumour deoxyribonucleic acid (ctDNA) in plasma. The trial is in progress; 28 of up to 370 planned patients have been recruited at the end of January 2019 (first patient in 31 October 2018). Clinical trial information: NCT03635021.

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.
