TPS2614 Background: Vascular endothelial growth factor (VEGF) is a potent factor in inducing angiogenesis. VEGF inhibitors have produced demonstrable but limited and transient clinical benefit for various cancers. One mechanism of resistance includes revascularization secondary to up-regulation of alternative pro-angiogenic signals such as platelet derived growth factor receptor (PDGF) and fibroblast growth factor receptor (FGFR) pathway. Nintedanib is an oral triple kinase inhibitor that blocks the VEGFR, PDGFR and FGFR pathways. Our study is using combination of Nintedanib (Nin) and Bevacizumab (Bev) which will block VEGF as well as salvage pathway of angiogenesis (PDGFR and FGFR). Phase I dose selection studies revealed that Nin is generally well tolerated (Clin Can Res 16:47, 2010). LUME-Lung 1 phase 3, international, double blind, placebo controlled trial using Nin and docetaxel in non-small cell lung cancer (NSCLC) showed significant improvement in progression free survival (PFS) regardless of histology and improvement in overall survival (OS) in lung adenocarcinoma (Lancet oncology 15:2, 2014). Methods: This is a phase 1b, open label, single institution trial with standard 3+3 design. Primary objective is to evaluate the safety and tolerability of combination of Nin and Bev. The secondary objective is to determine clinical efficacy (objective response), PFS, and evaluation of plasma levels of angiogenic and anti-angiogenic biomarkers like VEGF, PDGF, VEGF-R and FGF. Patients (pts) in cohort I will be treated with Bev 15 mg/kg day 1 intravenously every 3 weeks and Nin 150 mg orally (PO) twice daily (BID) from day 2-21. In the absence of dose limiting toxicities, Nintedanib dose will be increased to 200 mg PO BID in cohort II. Major inclusion criteria includes advanced solid tumors for which Bev has an indication (non-squamous, NSCLC, colon, ovarian, cervical and renal cancer), progression after at least 1 line of systemic treatment, and measurable disease. Pts with prior treatment with Bev can be enrolled. We will enroll 18 patients. Cohorts I has been completed without DLT (n = 3). Cohort II has enrolled 10 patients. Clinical trial information: NCT02835833.

9518 Background: The benefits of BRAF + MEK inhibition (dual combo) in pts with BRAF V600-mutant ( BRAFV600) melanoma are known. Preclinical data supports inhibiting CDK 4/6 and BRAF + MEK (triple combo) to improve antitumor activity. We report safety and preliminary efficacy from a phase 1b/2 study (NCT01543698) of encorafenib (ENCO; a selective BRAF kinase inhibitor), binimetinib (BINI; a MEK inhibitor), and ribociclib (RIBO; a CDK 4/6 inhibitor). Methods: Phase 1b of this open-label, multicenter study enrolled pts with confirmed BRAFV600advanced solid tumors. Escalating doses of RIBO 100 mg-600 mg QD for 3 wk on/1 wk off were administered with ENCO 200 mg QD + BINI 45 mg BID in successive cohorts (6 pts each) until the maximum tolerated or recommended phase 2 dose (RP2D) was reached. Due to potential pharmacokinetic interactions with RIBO, the ENCO dose was lower than the dual combo RP2D (450 mg QD). Dose escalations followed an adaptive Bayesian model. In phase 2, the triple combo was tested in pts with BRAFV600melanoma naïve to prior BRAF inhibitor treatment; the primary endpoint was objective response rate (ORR) per RECIST v1.1. Results: In phase 1b (n = 21), no dose-limiting toxicities were reported and the triple combo RP2D was ENCO 200 mg QD + BINI 45 mg BID + RIBO 600 mg QD. ENCO AUC was slightly lower than at the dual combo RP2D. In phase 2 (n = 42), 59.5% pts had an ECOG PS of 0 and 43% of pts had elevated lactate dehydrogenase. The most common (≥5%) grade 3/4 toxicities were neutropenia (26.2%), increased alanine transaminase (14.3%), diarrhea (7.1%), and anemia (7.1%). Ten pts (23.8%) discontinued treatment due to an AE, of which 4 were increased transaminases. The confirmed ORR was 52.4%, including 4 complete responses, 18 partial responses, and 15 pts with stable disease. Median duration of exposure in phase 2 was 9.1 mo (range, 0.0-21.6). Median progression-free survival was 9.0 mo (95% confidence interval, 7.0-11.1). Conclusions: Triple therapy with ENCO + BINI + RIBO in this small trial of pts with high disease burden was associated with responses in over half of pts and some evidence of increased toxicity. Clinical trial information: NCT01543698.

Abstract Background Larotinib is a new first-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor. This open-label, phase 1b study is aimed to evaluate the efficacy, safety of larotinib in patients with advanced esophageal squamous cell carcinoma (ESCC) with EGFR overexpression or amplification pretreated with one or more system regimens, and to recommend an appropriate dose for its further study. Methods Patients received larotinib orally at 3 doses (250, 300, 350 mg), once daily. Clinical response was evaluated every 8 weeks according to RECIST v1.1 criteria by both investigators and independent radiology review (IRC). Results 81 patients were enrolled. The investigator-assessed overall response rate (ORR) was 13.7% (10/73), all responses were observed in the 350 mg group of which ORR up to 20.0% (10/50), with 10 of them having EGFR overexpression and 4 having EGFR amplification. Per IRC assessment, ORR for all patients and 350 mg group were 13.9% (10/72) and 16.3% (8/50). In the 350 mg group, median overall survival (OS) and progression-free survival (PFS) were 8.0 (95% CI 4.9–10.2) months and 3.4 (95% CI 2.4–3.7) months, respectively. The most common treatment-related adverse events (TRAEs) were diarrhea, rash, and palmar-plantar erythrodysesthesia syndrome, elevated AST/ALT, vomiting, similarly with other EGFR TKIs. Conclusions Larotinib demonstrated promising antitumor activity and manageable safety profiles in patients with pre-treated advanced ESCC with EGFR overexpression or amplification, especially at the dose of 350 mg, which showed better efficacy and acceptable safety. A phase 3 study is underway on 350 mg larotinib in ESCC patients with EGFR overexpression. Trial registration This trial was retrospectively registered on 25/03/2019, NCT03888092. https://clinicaltrials.gov/ct2/show/NCT03888092.

5583 Background: Endometrial cancer is one of the most common gynecologic malignancies in the world. however, the effects of systemic chemotherapy are limited. The combination of targeted therapy with immunotherapy is a new research field in the treatment of malignant tumors. Anlotinib is a novel tyrosine kinase inhibitor with highly selective inhibition effects on multi-targets, especially on vascular endothelial growth factor receptor, Platelet-derived growth factor receptor and Fibroblast growth factor receptor. Sintilimab is a highly selective, fully humanized, monoclonal antibody, which blocks the interaction between Programmed death 1 and its ligands. This research aimed to evaluate the efficacy and safety of the combination of anotinib and sintilimab in patients with recurrent advanced endometrial cancer. Methods: Patients who received at least one platinum-based systemic chemotherapy, had an Eastern Cooperative Oncology Group performance status of 0 or 1 were considered eligible for enrollment. Sintilimab was administered intravenously (200mg，q3w); anlotinib was taken orally (12mg qd, d1-14, 21 days per cycle). The treatment was continued until disease progression, death or intolerant toxicity. The primary endpoint was objective response rate (ORR) and the secondary endpoints included duration of response, disease control rate (DCR), progression-free survival (PFS), overall survival and safety. Results: From November 2019 to to September 2020, 23 patients with a median age of 56 years (range: 37-70), FIGO stage IA (21.7%), IB (8.7%), II (4.4%), IIIA (13.1%)，IIIC (30.4%), IVB (21.7%) were enrolled. Among these participants, 22 patients were evaluable. The therapeutic evaluation showed the incidence of complete response, partial response, stable disease and progression disease was 13.6%, 63.7%, 13.6% and 9.1% respectively, yielding the ORR of 77.3% (95%CI: 58.3%-96.3%) and the DCR of 91.7% (95%CI: 79.8%-100%). ≥1 and ＜1 Combined Positive Score of PD-L1 expression were observed in 66.7% (14/21) and 33.3% (7/21) patients respectively, and the ORR was 92.9% (95%CI: 77.4%-100%) and 57.1% (95%CI: 18.4%-90.1%) in the two groups. The median time of the first response was 1.5 months (range, 0.7-12.8). The median PFS was not reached. Most of the occurring adverse events (AEs) were grade 1 or 2. Grade 3 AEs included ileus (4.3%), immune myocarditis (4.3%) immune peritonitis (4.3%), hand-foot syndrome (8.7%), neutropenia (4.3%), neutrophils decrease (4.3%), and hypertension (4.3%); Grade 4 AE was lymphocytosis (4.3%). Neither unexpected safety signals nor treatment-related death occurred. Conclusions: Anlotinib plus sintilimab showed a promising antitumor activity with a favorable toxicity profile for patients with recurrent advanced endometrial cancer. We will report more data in the future. Clinical trial information: NCT04157491.

2556 Background: Depletion of tumor-infiltrating CD25+ regulatory T cells (Tregs), which inhibit tumor-specific immune responses, could contribute to tumor eradication. Cami (ADCT-301), an anti-CD25, pyrrolobenzodiazepine-based antibody-drug conjugate, targets CD25+ Tregs. A mouse surrogate has shown potent antitumor activity in solid tumor models. Here we report preliminary data from the monotherapy arm of a phase 1b trial of Cami in pts with selected advanced solid tumors. Methods: The monotherapy dose-escalation part of this open-label study enrolled pts (aged ≥18 years) with selected advanced solid tumors and no suitable existing therapy. The primary objective was to characterize safety and tolerability, and to identify the recommended phase 2 dose of Cami monotherapy. Secondary and exploratory objectives included evaluation of preliminary antitumor activity, pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity. Pts received Cami every 3 weeks (1 cycle) with dose escalation per a 3+3 design. Disease control rate (DCR) was assessed (complete and partial responses [CR, PR] and stable disease). Results: At data cut-off (Dec 17, 2020), 44 pts were enrolled, with primary tumor types (stage IVA/B: 27 pts; 61.4%) of colorectal (15 pts; 34.1%), pancreatic (14 pts; 31.8%), head and neck, ovarian/fallopian tube, and renal cell carcinoma (all 3 pts; 6.8%), non-small cell lung cancer (2 pts; 4.5%), gastric, esophageal/GEJ, melanoma, and triple-negative breast cancer (each 1 pt; 2.3%). Median (range) age was 60.5 (33–82) years; median (range) number of prior systemic therapies was 4 (1–9). Pts received a median (range) of 2 (1–6) Cami cycles at doses of 20–150 µg/kg. Median (range) treatment duration was 22 (1–178) days. No dose-limiting toxicities were reported. The maximum tolerated dose (MTD) was not reached. All-grade treatment-emergent adverse events (TEAEs) in ≥20% pts were nausea (18 pts; 40.9%), decreased appetite and fatigue (each 16 pts; 36.4%), constipation (13 pts; 29.5%), abdominal pain (11 pts; 25%), and rash (10 pts; 22.7%). The only Grade ≥3 TEAE in ≥10% pts was anemia (5 pts; 11.4%). Grade 3 autoimmune AEs (colitis, immune-mediated AE, systemic inflammatory response syndrome) and neurologic AEs (dysphagia and asthenia, but not GBS) were reported in 3 (6.8%) and 2 (4.5%) pts, respectively. 1 (2.3%) Cami-related TEAE led to treatment withdrawal; no Cami-related TEAEs were fatal. DCR was 25% (95% CI: 11.1, 34.7); 11/44 pts attained stable disease. No pts had CR or PR. Conclusions: Dose escalation of Cami monotherapy is complete. The safety profile is encouraging and MTD was not reached. PK/PD data will be presented. 150 µg/kg is the highest dose investigated for single-agent Cami and the highest to be investigated combined with pembrolizumab in selected advanced solid tumors in the current protocol.

7119 Introduction: AMG 706 is an investigational, oral, multi-kinase inhibitor with both antiangiogenic and direct antitumor activity targeting VEGF, PDGF, and Kit receptors. Panitumumab, a fully human monoclonal antibody directed against the epidermal growth factor receptor (EGFr), has shown antitumor activity and acceptable safety in pts with solid tumors. Methods: This is an ongoing, multicenter, dose finding, phase 1b study of AMG 706 with panitumumab and CP in pts with advanced NSCLC. Primary objectives were to assess the safety and PK of AMG 706; secondary objectives included drug exposure and objective response rates. Pts had stage IIIB/IV NSCLC, ECOG score of 0–1, no symptomatic or untreated CNS metastases, and no prior chemotherapy for NSCLC (segments A&C) or ≤ 1 regimen for NSCLC (segment B). AMG 706 was given orally either QD (50 mg or 125 mg) or BID (75 mg) with CP Q3W (P:200 mg/m2; C: AUC = 6 mg/mL · min; Segment A), with panitumumab (9.0 mg/kg Q3W; Segment B), or with CP+ panitumumab (Segment C). AMG 706 was dosed continuously in 21-day cycles (days 3–21 in cycle 1; days 1–21 in cycle 2 and beyond); pts were sequentially enrolled into escalating AMG 706 dose cohorts. Results: As of 9/05, 22 pts were enrolled (10 in A, 12 in B) into AMG 706 dose cohorts of 50 mg and 125 mg QD. In A and B, respectively, 7 and 6 pts were men; median (range) age was 60.5 (60, 74) and 60.5 (55.7, 71.0). One pt in the 125 mg QD cohort in Segment B had grade (gr) 5 pneumonia. Treatment-related adverse events occurring in >5% of all patients are summarized ( table ). Preliminary data showed that AMG 706 PK profiles were similar when administered with CP either 30 min or 48 hrs apart. At 50 mg QD, there was no effect of AMG 706 on the PK of P. Conclusions: Preliminary data indicate that AMG 706 can be combined safely with CP or panitumumab in pts with advanced NSCLC and that there is no effect on the PK of AMG 706 or P. Updated data will be presented. [Table: see text] [Table: see text]

8074 Background: ABT-869 is a novel orally active, potent and specific inhibitor of vascular endothelial growth factor and platelet derived growth factor receptor tyrosine kinases. Methods: This ongoing, open-label, randomized, multicenter phase 2 trial of ABT-869 at 0.10 mg/kg daily (Arm A) and 0.25 mg/kg daily (Arm B) until progressive disease (PD) or intolerable toxicity, was initiated to assess antitumor activity and toxicity of ABT-869 in patients (pts) with NSCLC. Eligibility criteria included locally advanced or metastatic NSCLC; ≥ 1 prior systemic treatment, and ≥1 measurable lesion by RECIST criteria. The primary endpoint was the progression free (PF) rate at 16 wks. Secondary endpoints were objective response rate (ORR), time to progression (TTP), progression free survival (PFS) and overall survival (OS). CT scans were assessed by the investigator and centrally; central assessment results are provided. Results: 138 patients (pts) were enrolled from 08/07–10/08 from 27 centers with interim data available for 94 pts (Arm A, n=43; Arm B; n=51). Median age was 64 years and 62 years in Arm A and B respectively. For the interim analysis population (Arm A, n=24; Arm B, n=24), 16 (33.3%) pts were PF at 16 wks: 7 (29.2%) in Arm A and 9 (37.5%) in Arm B. The ORR in Arm A (n=30) was 0% and 7.3% in Arm B (n=41). The median TTP and median PFS were 110 and 109 days, and 112 days and 108 days in Arm A and B, respectively. The most common adverse events (AEs) in Arm A were fatigue (35%), nausea (21%), and anorexia (21%), and in Arm B were hypertension (51%), fatigue (51%), diarrhea (43%), anorexia (41%), nausea (31%), proteinuria (31%) and vomiting (26%). The most common grade 3/4 toxicities in the Arm A were fatigue (7%), ascites (5%), dehydration (5%), pleural effusion (5%), and in the Arm B were hypertension (23%), fatigue (8%), PPE syndrome (8%), dyspnoea (6%) and stomatitis (6%). Most AE's were mild/moderate and reversible with interruptions/dose reduction/or discontinuation of ABT-869. Conclusions: ABT-869 demonstrates an acceptable safety profile and appears to be active in NSCLC patients. [Table: see text]
