9066 Background: Taletrectinib (AB-106; DS-6051b) is a potent, selective ROS1/NTRK inhibitor. In two phase I trials, NSCLC patients (pts) with ROS1 fusion who received taletrectinib as first line ROS1 TKI had an objective response rate (ORR) of 66.7% (6/9) and median progression-free survival (PFS) of 29.1 mo (Sai-Hong Ignatius Ou et al., JTO Clinical and Research Reports, 2020). TRUST (NCT04395677) is an ongoing, multicenter, phase II study of taletrectinib in Chinese NSCLC pts with ROS1 fusion. Methods: The ROS1 TKI naïve or crizotinib pre-treated NSCLC patients with ROS1 fusion were treated with taletrectinib 400 or 600 mg QD. ROS1 testing was performed in each center and confirmed by central lab using RT-PCR. The primary endpoint was ORR (complete response [CR] + partial response [PR]) by IRC assessment. Secondary endpoints were disease control rate (DCR; CR + PR + stable disease), PFS and safety, etc. The pharmacokinetics (PK) of taletrectinib following 400 or 600 mg QD regimen was also evaluated. Results: As of the data cutoff (15 Jan 2021), 22 pts had received taletrectinib treatment. Median age was 54.5 years (range, 32-77 years;); 18.2% (4/22) had central nervous system metastases; ECOG performance status was 0 in 13.6% (3/22) of pts and 1 in 86.4% (19/22) of pts. Most pts (54.5%, 12/22) had prior systematic chemotherapy; 31.8% (7/22) of pts had prior crizotinib treatment. ORR by investigator among the crizotinib naïve pts with tumor assessment (N = 11) was 100% (95% CI, 72%-100%); 81.8% (18/22) of pts had treatment-emergent adverse events (TEAEs), including nausea, vomiting, diarrhea, transaminase elevation, white blood cell count decrease/neutrophil count decrease, etc. 13.6% (3/22) were grade ≥ 3, including fatigue (4.5%, 1/22), white blood cell decrease (4.5%, 1/22) and transaminase elevation (4.5%, 1/22).TEAEs led to dose interruption in 3 pts (13.6%), including dose reduction in 2 pts (9.1%). Taletrectinib in plasma approximately reached steady state on Cycle 1 Day 8 with 2- to 3- fold accumulations of exposure, which was consistent with results observed in the phase I trials. Conclusions: Taletrectinib demonstrated promising clinical activity with high ORR and good tolerability in ROS1 fusion positive NSCLC patients. The safety and PK profiles following taletrectinib treatment was generally consistent with the phase I trials. Clinical trial information: NCT04395677. Clinical trial information: NCT04395677.

e21062 Background: Platinum-based chemotherapy is the standard therapy for the patients(pts) with EGFR-mutation–positive advanced NSCLC failed to prior EGFR TKI therapies. However, the IMpower150 study subgroup analyses showed Atezolizumab (PD-L1) plus bevacizumab and chemotherapy improved overall survival in EGFR TKI treated NSCLC. This ongoing phase I/II study designed to assess the benefit of the chemo-free combination of TQ-B2450, a humanized PD-L1 mAb, plus anlotinib in EGFR+ advanced NSCLC pts failed to prior EGFR TKI therapies. Methods: Pts with EGFR+ advanced NSCLC who failed to prior EGFR TKI therapies were eligible. Pts with previous received platinum-based chemotherapy were excluded. Anlotinib was given orally at dose of 8mg to 12mg for 2 weeks of a 21-day cycle (days 1-14), with TQ-B2450 given at 1200mg every 3 weeks on day 1. Phase I determined RP2D. In the phase II part, pts were assessed for efficacy and tolerability. The primary endpoint for the phase II part is the progression free survival (PFS). Secondary endpoints were objective response rate (ORR) disease control rate (DCR), overall survival (OS), and safety. Assuming an expected the median PFS of 9 months (5 months in chemotherapy), and a loss to follow-up of 10%, a total of 54 pts were required to have 90% power at a two-tailed alpha of 0.05 at the phase II part. Results: As of 12 Jan 2021, 22 pts were enrolled (9 in phase 1, 14 in phase 2). 18 pts were included in efficacy and safety analysis. The median age was 64.5 years with 61% male. 50% pts harbored EGFR exon19 deletion, 44% pts had exon21 L858R mutation. While 39% pts had T790M mutation who progressed after osimertinib treatment. The dose escalation cohort included 9 pts, no dose limiting toxicity occurred. 13 pts in the phase II part were administered with dose of 12 mg for anolitinib and 1200mg for TQ-B2450. Of the evaluable pts(n = 18), ORR was 11.1%, DCR was 77.8%, median PFS was 8.0 months (95% CI 4.9 to 11.1). Most frequent TRAE included hypertension (27.8%), hand and foot skin reaction (22.2%) and proteinuria (16.7%). Grade 3 TRAE occurred in 16.7% pts(3/18 pts), all were hypertension, and no Grade 4/5 TRAE were observed. Dose delay due to TRAE occurred in 22.2% patients while no one discontinued treatment due to TRAE. Conclusions: The chemo-free combination of TQ-B2450, a PD-L1 mAb, plus anlotinib has shown a promising anti-tumor efficacy with a more favorable safety profile for pts with EGFR+ advanced NSCLC who failed to prior EGFR TKI therapies. Pts will be continuously monitored for safety and efficacy readouts (PFS, DOR and OS). Clinical trial information: ChiCTR1900026273. Clinical trial information: ChiCTR1900026273.

e21680 Background: L-DOS47, a cancer therapeutic designed to exploit the acidic tumour extracellular environment, consists of urease conjugated to an anti-CEACAM6 camelid monoclonal antibody. The antibody serves as a targeting agent to deliver urease to tumor sites, while the urease enzyme converts urea, an abundant natural metabolite, into ammonia and generates a local pH increase. The combined effect of ammonia toxicity and pH increase is cytotoxic to cancer cells. An additive cytotoxic effect of L-DOS47 and pemetrexed/carboplatin has been observed against the A549 human lung adenocarcinoma cell line. L-DOS47 has been shown in a previous phase I clinical trial to be safe and well tolerated at doses up to 13.55 µg/kg. The current phase I study was designed to define the maximum tolerated dose of L-DOS47 in combination with pemetrexed/carboplatin. Methods: Stage IV (TNM M1a and M1b) histologically confirmed non-squamous NSCLC patients (aged ≥18 yrs, ECOG PS ≤1) received up to four cycles of L-DOS47 in combination with standard of care doses of pemetrexed/carboplatin. L-DOS47 was administered weekly over 21 days in each treatment cycle. Seven planned dosing cohorts (0.59, 0.78, 1.5, 3.0, 6.0, 9.0, 12.0 μg/kg) employed a standard 3+3 design for the first two and the last two cohorts, and an accelerated 1 + 2 design for the middle three cohorts. Dose levels of L-DOS47 were escalated following a review of safety data by the Trial Steering Committee. Results: Fourteen (14) patients were enrolled across 6 dosing cohorts before recruitment was halted. Median age was 65.1 years, with 50.0% male and 78.6% Caucasian. 57.1% of patients had an ECOG score of 0, and 42.9% had an ECOG score of 1. The maximum tolerated dose (MTD) could not be determined as none of the patients experienced a dose limiting toxicity (DLT). 50.0% of patients experienced at least one treatment emergent adverse event (TEAE) assessed as study drug-related, with 14.3% of patients experiencing at least one grade 3/4 drug-related toxicity. Of 12 patients evaluable for efficacy, 5 patients (41.7%) had a partial response (PR), 4 patients (33.3%) experienced stable disease (SD) and 3 patients (25.0%) had progressive disease (PD). The objective response rate is 41.7%. The clinical benefit rate is 75.0%. Conclusions: L-DOS47, in combination with pemetrexed/carboplatin, appears to be well tolerated with promising anti-tumor activity against non-squamous NSCLC. Clinical trial information: NCT02309892.

TPS3623 Background: Immune checkpoint inhibitor (ICI) was reported to show durable responses in patients with MSI-H (Microsatellite Instability-High) metastatic colorectal cancer (mCRC). On the other hand, for patients with MSS (Microsatellite Stable) mCRC, ICI monotherapy achieved no response. Recently, WNT/β-catenin signaling has been reported to be involved in the elimination of tumor-infiltrating lymphocytes and the resistance of anti-PD-L1 antibodies. CRC is representative cancer with WNT/β-catenin pathway activation. Furthermore, STAT3 has also been reported to be a key driver of this immune evasion. Considering these rationales, the blocking of these signaling pathways with ICI may enhance antitumor immune response. Therefore, we initiated phase I/II study to assess efficacy and safety for the combination of BBI608, which blocks STAT3 and WNT/β-catenin signaling, with pembrolizumab in patients with mCRC. Methods: The eligibility criteria were patients with gastrointestinal cancer not responded to or intolerant of standard chemotherapies (SOC) for phase I part, and MSS mCRC refractory or intolerant to fluoropyrimidine, irinotecan, oxaliplatin, and anti-EGFR antibody (if wild-type RAS) for Cohort B in phase II part. For Cohort A, MSI-H mCRC refractory or intolerant to the SOC, irrespective of anti-EGFR antibody are investigated. Phase I part was designed to determine the recommended phase II dose in a “3+3” cohort-based dose escalation design of BBI608 (240mg BID every day on level 1 and 480mg BID every day on level 2) with pembrolizumab (200mg/body q3w). Primary endpoint of the phase II part is Immune-related objective response rate (irORR) determined by their Response Evaluation Criteria In Solid Tumors (irRECIST). A null hypothesis and alternative hypothesis for cohort B are irORR = 5% and 20%, respectively. Required sample size for Cohort B was 40 with a one-sided alpha of 5% and power of 90%. Required sample size for Cohort A (10 patients) was determined in an exploratory manner. We also investigate biomarker study using paired samples of both tumor biopsy and blood. The enrollment to phase I part began in November 2016. Clinical trial information: NCT02851004. Clinical trial information: NCT02851004.

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.

e16121 Background: Programmed cell death protein‐1(PD-1) targeted immunotherapy is a promising treatment strategy for advanced hepatocellular carcinoma. Anti-PD-1 inhibitor camrelizumab showed antitumour activity in phase II studies of advanced hepatocellular carcinoma, with manageable toxicities. This study evaluates safety and efficacy of camrelizumab in patients with advanced hepatocellular carcinoma. Methods: This is a multicentre, real‐world trial done at thirty-three centres in Fujian Province, China. Eligible patients were aged 18 to 75 years was diagnosed by China Liver Cancer Staging(CNLC) 2019 clinical diagnostic criteria or with a histological or cytological diagnosis of advanced hepatocellular carcinoma, unresectable or had progressed on or were intolerant to previous systemic treatment, and had an Eastern Cooperative Oncology Group performance score of 0-1. Patients were received camrelizumab 200 mg intravenously every 2 weeks plus other treatments, such as molecular targeted drug, transcatheyer artetial chemoembolization, radiotherapy and chemotherapy. The primary endpoints were progression-free survival. Safety was analysed in all treated patients. Follow-up is ongoing. Results: Between Mar 12, 2020, and Dec 25, 2020, 63 patients were screened for eligibility, of whom 41 eligible patients received camrelizumab were recruited and among whom 15 received apatinib, 16 received lenvatinib, 2 received sorafenib and 1 received regorafenib. Median followup was 5.28 months (IQR 1.63–10.20). Objective response was reported in 12 (29.3%; 95% CI 16.1–45.5) of 41 patients. Disease control was reported in 34 (82.9%; 95% CI 67.9–92.8) of 41 patients. The median PFS was not reached, and expected more than 9 months. Grade 3 or 4 treatment-related adverse events occurred in 21 (51.2%) of 41 patients; the most common were increased gamma-glutamyltransferase (15 [36.6%]) and increased aspartate aminotransferase (7 [17%]). One death was judged by the investigators to be potentially treatment-related (due to upper gastrointestinal bleeding). Conclusions: Camrelizumab showed promising efficacy and safety in pretreated Chinese patients with advanced hepatocellular carcinoma, and might represent a new treatment option for these patients.

2039 Background: Ixabepilone is the first analog in a new class of antineoplastic agents, the epothilones, which stabilizes microtubules and induces apoptosis. Ixabepilone has shown clinical activity in a broad range of tumors. Methods: This Phase I trial was designed to establish the maximum tolerated dose (MTD), dose-limiting toxicity (DLT), efficacy, safety, pharmacokinetics and pharmacodynamics of ixabepilone when administered as a 1-hour infusion every 3 weeks to patients with advanced solid tumors or lymphoma. Eligible patients were aged ≥18 years with histologically/cytologically confirmed non-hematologic cancer, or a pathologic diagnosis of relapsed/primary refractory non-Hodgkin’s lymphoma (NHL) or relapsed/primary refractory mantle cell lymphoma, with ≤CTC Grade 1 neuropathy. Ixabepilone doses ranged from 7.5–65 mg/m2. Response was assessed every 6 weeks using RECIST. DLT was defined as Grade 4 neutropenia and/or febrile neutropenia, thrombocytopenia, ≥Grade 3 nausea/vomiting and non-hematologic toxicity, or treatment delay of >2 weeks due to delayed recovery. Results: Of 61 patients (median age 58, range 18–81), 75% had solid tumors; 25% had lymphoma. 98% and 67% of patients had received one or ≥ two prior chemotherapy regimens, respectively. The MTD of ixabepilone as a 1-hour infusion every 3 weeks was established as 50 mg/m2. The most common DLTs were neutropenia, myalgia, arthralgia and stomatitis/pharyngitis. A total of eight patients (13%) achieved a durable objective response. Complete responses were achieved in two patients with primary peritoneal cancer and NHL. A partial response was seen in six patients. The most common Grade 3/4 treatment-related adverse events (only observed at doses ≥40 mg/m2) were sensory neuropathy (13%), fatigue (13%), myalgia (10%), arthralgia (7%), nausea (5%), febrile neutropenia (5%) and neutropenia (5%). Recovery to baseline or ≤Grade 1 neuropathy occurred in some patients. Conclusions: The recommended dose of ixabepilone for the initiation of Phase II studies based on this study is 50 mg/m2 over 1 hour every 3 weeks. Ixabepilone demonstrates promising safety in patients with solid tumors or lymphoma who have failed standard therapy. Encouraging activity was reported in several tumor types. [Table: see text]

8008 Background: Human lung cancer expresses high levels of PD-L1, which may inhibit anti-cancer immune responses. MPDL3280A, a human monoclonal Ab containing an engineered Fc-domain designed to optimize efficacy and safety, targets PD-L1, blocking PD-L1 from binding its receptors, including PD-1 and B7.1. Methods: Pts with squamous or nonsquamous NSCLC received MPDL3280A IV q3w at doses between 1-20 mg/kg in a Ph I expansion study. Pts were treated for up to 1 y. Objective response rate (ORR) was assessed by RECIST v1.1. Reported ORR includes u/cCR and u/cPR. Results: As of Jan 10, 2013, 53 NSCLC pts were evaluable for safety and treated at doses of ≤1 (n=2), 10 (n=10), 15 (n=19) and 20 mg/kg (n=22). Pts had a median age of 61 y (range 24-83 y), 98% were PS 0-1, 89% had prior surgery and 55% had prior radiotherapy. 98% of pts received prior systemic therapy. Pts received treatment for a median duration of 106 days (range 1-324) of MPDL3280A. The incidence of all G3/4 AEs, regardless of attribution, was 34%, including pericardial effusion (6%), dehydration (4%), dyspnea (4%) and fatigue (4%). No G3-5 pneumonitis or diarrhea was reported. 37 NSCLC pts enrolled prior to Jul 1, 2012, were evaluable for efficacy. RECIST responses were observed at dose levels between 1 and 20 mg/kg, with all responses ongoing or improving. An ORR of 24% (9/37) was observed in pts with squamous and nonsquamous histologies, including several with rapid tumor shrinkage. Additional pts had delayed responses after apparent radiographic progression (not included in the ORR). The 24-week PFS was 48%. Analysis of biomarker data from archival tumor samples demonstrated a correlation between PD-L1 status and efficacy. Pts who were PD-L1 tumor status–positive showed an ORR of 100% (4/4) and a PD rate of 0% (0/4), while pts who were PD-L1 tumor status–negative showed an ORR of 15% (4/26) and a PD rate of 58% (15/26). Updated data will be presented. Conclusions: Treatment with MPDL3280A was well tolerated, with no pneumonitis-related deaths. Rapid and durable responses were observed. PD-L1 tumor status correlated with response to MPDL3280A. Clinical trial information: NCT01375842.

264 Background: Stage IV pancreatic cancer is a lethal disease with limited treatment options. Current standard practice is combination chemotherapy with FOLFIRINOX or Gemcitabine + Abraxane. Despite these two new treatment options, the response rate and survival are limited in stage IV pancreatic cancer. The glycolic and mitochondrial metabolisms are aberrant in pancreatic cancer and translate into chemo-resistance. Inhibition of glutamine metabolism can potentially synergize with therapies that increase intracellular reactive oxygen species such as chemotherapy. CPI -613 is a novel anti-mitochondrial developed by Cornerstone Pharmaceuticals. Methods: A phase I clinical trial with mFOLFIRINOX+ CPI-613 in never treated for stage IV pancreatic cancer patients was initiated. The goals of this phase 1trial are: (1) To determine the Maximum Tolerated Dose (MTD) of CPI-613, when used in combination with mFOLFIRINOX, in patients with metastatic pancreatic cancer, (2) To assess the safety of CPI-613/ mFOLFIRINOX combination in patients with metastatic pancreatic cancer, and (3) To obtain preliminary data on efficacy of treatment with CPI-613/ mFOLFIRINOX Results: The MTD for CPI 613 was identified at 500mg/m2. The treatment combination is feasible and well-tolerated. The combination treatment was not found to have higher toxicity than FOLFIRINOX alone. The objective response rate was 53.9 % which is higher than FOLFIRINOX alone (reported as 31.6%). One patient has a complete radiologic and clinical response and two other patients have near complete responses. Conclusions: The preliminary efficacy data of this phase I clinical trial will inform a multi-institutional randomized phase II study of FOLFIRINOX vs. m FOLFIRINOX+ CPI613 in the near future. Clinical trial information: NCT01835041.

4506 Background: PAZ is indicated for the treatment of aRCC. The combination of an anti-angiogenic agent and immunotherapy may improve anti-tumor activity. We report preliminary safety and efficacy results of the phase I part of the study. Methods: Twenty pts were originally enrolled in cohorts A and B assessing PAZ 800 mg and 600 mg, respectively, both with 2mg/kg (Q2W and then Q3W) PEM to determine the maximum tolerated dose. Due to dose limiting liver toxicity, cohort C was opened to assess if the sequential schedule of 9 weeks PAZ run-in followed by PAZ+PEM would improve safety. Strict safety criteria for initiating PAZ+PEM were set. The data from this ongoing study are presented given the limited information available on the combination of TKI + PD-1 inhibitors in RCC. Results: Overall, 35 pts were treated; 5 out of 15 pts in cohort C received PAZ+PEM at the data cut-off. Three dose-limiting toxicities (DLT) occurred in cohort C in pts receiving PAZ+PEM; updated DLTs in all cohorts are reported in Table. G3/4 AEs were observed in 90% of pts in cohorts A and B and in 80% of pts in cohort C receiving PAZ+PEM. No G3/4 ALT/AST elevation was reported in cohort C PAZ+PEM while they were observed in 70% and 60% in cohorts A and B, respectively. Best overall response (CR+PR) was reported in 6, 2 and 1 pts receiving PAZ+PEM in cohorts A, B and C, respectively. Conclusions: Results from cohorts A and B showed significant hepatotoxicity. The sequential schedule PAZ → PAZ+PEM has shown reduced hepatotoxicity and preliminary signs of efficacy but overall limited tolerability. PAZ+PEM is not suitable to test in a larger cohort.

e21509 Background: Participation of children with advanced solid cancers in phase I trials raises ethical and logistic dilemmas. Life-expectancy beyond 8-12 weeks is a common inclusion criterion, but it can be difficult to gauge. This multicentric European study assessed the mortality and survival rates in pediatric phase I trials. Methods: Retrospective study of patients aged < 18 years with solid tumors enrolled in phase I trials in ITCC centres between 2015-2017. Outcome variables were described and prognostic factors analysed. Results: 256 patients across 12 centres in 5 countries were eligible. Median age 11.8 years (range, 0.5-17.9). Female:Male ratio 1:1.9. Tumor location: central nervous system (CNS) 66% vs extra-CNS 34%. Main diagnoses: 22% soft tissue sarcomas, 13% high grade gliomas, 11% osteosarcomas. Most frequent therapy: single targeted agent (63%). Ten cases (4%) were not evaluable for response and 128 (50%) had progressive disease at first evaluation. Best responses were complete in 12 cases (5%), partial in 29 (11%) and stable disease in 77 (30%). Median follow-up 7 months (range, 0.5-42.4). Median Time On Study (TOS) 2.1 months (range, 0.2-38.1). The 30 and 90-day mortality on trial were 3% (8/256) and 21% (54/256), respectively. The 90-day survival (95%CI) for patients with CNS vs extra-CNS tumors was 88% (78-93) vs 76% (68-82), respectively. One-year Overall Survival (95%CI) for the whole sample was 40% (33-46). No toxic deaths on trial were reported. Twenty-five cases (10%) survived ≥365 days on trial. Median TOS 21.5 months (range, 12.3-38.1). Compared to patients who died within 365 days from Cycle1-Day1, those on trial ≥365 days had lower rates of metastatic disease (74% vs 28%, respectively, p < 0.001), higher objective response rates (13% vs 44%, respectively, p < 0.001) and higher disease stabilization (27% vs 56%, respectively, p < 0.001). Conclusions: Currently few patients die within the first cycle of treatment. However a fifth of all patients died within 3 months from trial initiation. Patients with CNS tumors have comparable survival rates to those with extra-CNS and should not be excluded from phase I trials solely because of their diagnosis. The survival rates beyond one year remain modest.
