Bispecific T Cell Engager

TPS2071 Background: GBM is the most aggressive primary brain tumor in adults and is extremely difficult to treat. Patients with GBM tend to progress rapidly within weeks or months. Median overall survival is only 12–15 months despite aggressive treatment, and less than 5% of patients survive 5 years. GBM also severely impacts quality of life and cognitive function. Approximately 50% of GBM tumors test positive for amplification or mutation of the epidermal growth factor receptor (EGFR), the most common of which is the EGFRvIII gain-of-function mutation. AMG 596 is a bispecific T cell engager (BiTE®) antibody construct designed to crosslink and engage CD3-positive T cells to EGFRvIII-positive tumor cells, inducing tumor cell lysis and T cell proliferation. A clinical trial is being conducted for this novel immunotherapy agent in patients with EGFRvIII-positive GBM. Methods: NCT03296696 is a phase 1, first-in-human, open-label, sequential dose-escalation and dose-expansion study evaluating the safety, tolerability, and pharmacokinetics and pharmacodynamics (PK/PD) of AMG 596 in patients with EGFRvIII-positive GBM. AMG 596 is administered via continuous intravenous infusion. The study is expected to enroll approximately 82 patients total and comprises two groups (Group 1: patients with recurrent GBM; Group 2: patients with newly diagnosed GBM in the maintenance treatment phase after standard of care). Key inclusion criteria include: male or female; ≥ 18 years of age; with pathologically documented and diagnosed grade IV GBM; Eastern Cooperative Oncology Group performance status ≤ 1; life expectancy ≥ 3 months per study investigator; and acceptable renal, hematological, and hepatic function. The primary endpoint evaluates the safety and tolerability of AMG 596 via collection of treatment-emergent adverse events. Additional endpoints include objective response rate per modified Response Assessment in Neuro-Oncology Criteria and PK/PD analyses of AMG 596 in serum. The study began enrolling patients in April 2018 and enrollment is ongoing. For more information, please contact Amgen Medical Information: [email protected].

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.

Abstract OBJECTIVES The class III variant of the epidermal growth factor receptor (EGFRvIII) represents the most common EGFR mutation in GBM. AMG 596 is a bispecific T cell engager (BiTE®) molecule designed to engage a patient’s own CD3-positive T cells to EGFRvIII-positive tumor antigens. This is the first clinical data readout for AMG 596. METHODS This phase 1, first-in-human, open-label, sequential dose-escalation/expansion study evaluates continuous intravenous AMG 596 in patients with EGFRvIII-positive GBM or malignant glioma in recurrent (Group 1) or newly diagnosed in maintenance treatment (Group 2) settings. Eligible patients: adults with EGFRvIII-positive GBM or malignant glioma; ≤2 mg/day dexamethasone, ECOG performance status ≤1; life expectancy ≥3 months; and acceptable renal, hematological, and hepatic function. The primary objective evaluates safety and tolerability. Additional assessments include objective response rate per modified Response Assessment in Neuro-Oncology (RANO) Criteria. RESULTS As of June 2019, 15 rGBM patients (Group 1) were enrolled; 14 patients received ≥1 dose AMG 596. 14/15 (93.3%) patients were evaluable at time of analysis (safety analysis set). Median age was 54.5 years (range, 44–68); 50% were male. Seven patients discontinued for progressive disease (PD). AEs occurred in all patients and were serious in 7/14 (50%). None resulted in discontinuation; two (14.3%) fatal AEs were related to PD. Headache and depressed consciousness (both n=2, 14.3%) were the most common grade ≥3 treatment emergent AEs. In patients with sufficient follow-up to assess response (n=8), 1 (12.5%) achieved partial response, 2 (25%) had stable disease, 4 (50%) had PD at initial scan, and 1 (12.5%) discontinued treatment for PD. Semi-quantitative EGFRvIII expression analysis revealed a median H-score of 115 (range, 8–280). CONCLUSION This interim analysis suggests a first indication that AMG 596 may be well-tolerated and offer anti-tumor activity in patients with rGBM. Enrollment is ongoing and additional data will be presented. NCT03296696.

TPS8055 Background: LEN + DEX (Rd) is approved for pts with newly diagnosed MM, including those who are transplant non-eligible (TNE). DURVA is a monoclonal antibody to programmed death ligand 1 (PD-L1) that blocks PD-L1 binding to programmed death-1 (PD-1). Preclinical studies showed anti-MM immune responses with PD-1/PD-L1 blockade that were enhanced with LEN (Görgün et al, 2015). Here, we present a phase 1/2, multicenter, open-label trial in progress (MEDI4736-MM-002) designed to evaluate DURVA in combination with LEN ± DEX in a target population of pts who are TNE and/or with high-risk NDMM. Methods: Enrollment of up to 138 pts from the US, Canada, and Europe is planned to determine the recommended dose of DURVA (primary endpoint) with LEN ± DEX for the treatment (Tx) of NDMM. Key secondary endpoints include safety, response outcomes, pharmacokinetics, progression-free survival, and overall survival. Pts with previously untreated MM with ≥ 1 of the following will be included: 1 of the CRAB criteria or clonal bone marrow plasma cells ≥ 60% and an Eastern Cooperative Oncology Group performance status of ≤ 2. Pts with a history of primary immunodeficiency will be excluded. Each independent cohort (A, B, C) will enroll 6 pts in parallel in the dose-finding phase (Table). Dose-limiting toxicities will be evaluated during the first cycle of Tx. The optimal regimen will be determined from the dose-finding phase and a parallel dose-expansion phase of up to 40 pts per cohort. Tx will continue until progressive disease or unacceptable toxicity. To date, 15 pts have enrolled. Clinical trial information: NCT02685826. [Table: see text]

TPS9598 Background: Findings from phase 1 and 2 studies suggest that targeting programmed death 1 (PD-1)/PD-L1 pathway can provide durable antitumor activity in patients with local/regionally advanced or metastatic cSCC and may be a promising treatment option. The open-label, single-arm, phase 2 KEYNOTE-629 trial (NCT03284424) will be conducted to test the clinical activity of the PD-1 inhibitor pembrolizumab in locally advanced, unresectable, and recurrent or metastatic cSCC. Methods: Patients will receive intravenous pembrolizumab 200 mg every 3 weeks for up to 35 infusions (≤24 months) or until protocol-specified treatment discontinuation. Treatment will not be stratified in this study. Eligibility criteria include age ≥18 years; locally advanced cSCC for which the patient is ineligible for resection or radiotherapy (RT) or for which the patient previously underwent RT to the index site or systemic therapy for curative intent; presence of measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1; and Eastern Cooperative Oncology Group performance status 0 or 1. Treatment will be discontinued for progressive disease, unacceptable toxicity, intercurrent illness preventing administration, investigator’s decision, patient withdrawal of consent, pregnancy, or cessation for administrative reasons. Response will be assessed by imaging 6 weeks after treatment initiation, every 6 weeks through year 1, and every 9 weeks thereafter or more frequently if clinically indicated. After disease progression or the start of new anticancer therapy, the patient will be followed up every 12 weeks until death, consent withdrawal, or study end, whichever occurs first. Safety will be monitored throughout the study and for 30 days after treatment end or 90 days if the patient experiences serious adverse events. The primary end point is objective response rate (RECIST v1.1). Secondary end points include response duration, disease control rate, progression-free survival, overall survival, and safety. Recruitment is ongoing in 10 countries and will continue until approximately 50 additional patients with locally advanced, unresectable cSCC are enrolled. Clinical trial information: NCT03284424.

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.

BackgroundNo treatment demonstrated to improve survival in patients with recurrent glioblastoma (rGB) in a randomized trial. Combining axitinib with the programmed cell death ligand 1 blocking monoclonal antibody avelumab may result in synergistic activity against rGB.MethodsAdult patients with rGB following prior surgery, radiation therapy and temozolomide chemotherapy were stratified according to their baseline use of corticosteroids. Patients with a daily dose of ≤8 mg of methylprednisolone (or equivalent) initiated treatment with axitinib (5 mg oral two times per day) plus avelumab (10 mg/kg intravenous every 2 weeks) (Cohort-1). Patients with a higher baseline corticosteroid dose initiated axitinib monotherapy; avelumab was added after 6 weeks of therapy if the corticosteroid dose could be tapered to ≤8 mg of methylprednisolone (Cohort-2). Progression-free survival at 6 months (6-m-PFS%), per immunotherapy response assessment for neuro-oncology criteria, served as the primary endpoint.ResultsBetween June 2017 and August 2018, 54 patients (27 per cohort) were enrolled and initiated study treatment (median age: 55 years; 63% male; 91% Eastern Cooperative Oncology Group Performance Status 0–1). Seventeen (63%) patients treated in Cohort-2 received at least one dose of avelumab. The 6-m-PFS% was 22.2% (95% CI 6.5% to 37.9%) and 18.5% (95% CI 3.8% to 33.2%) in Cohort-1 and Cohort-2, respectively; median overall survival was 26.6 weeks (95% CI 20.8 to 32.4) in Cohort-1 and 18.0 weeks (95% CI 12.5 to 23.5) in Cohort-2. The best objective response rate was 33.3% and 22.2% in Cohort-1 and Cohort-2, respectively, with a median duration of response of 17.9 and 19.0 weeks. The most frequent treatment-related adverse events were dysphonia (67%), lymphopenia (50%), arterial hypertension and diarrhea (both 48%). There were no grade 5 adverse events.ConclusionThe combination of avelumab plus axitinib has an acceptable toxicity profile but did not meet the prespecified threshold for activity justifying further investigation of this treatment in an unselected population of patients with rGB.

LBA348 Background: In the phase III AXIS trial, second-line therapy with axitinib resulted in significantly longer progression-free survival (PFS) versus sorafenib for mRCC. We conducted a multicenter, randomized, open-label, phase III trial to compare PFS of axitinib vs sorafenib as first-line therapy. Methods: Patients with untreated, measurable (RECIST v1.0), clear‑cell mRCC and Eastern Cooperative Oncology Group performance status (PS) 0 or 1 were randomized 2:1 to axitinib 5 mg twice daily (BID) or sorafenib 400 mg BID. Randomization was stratified by PS. Primary endpoint was PFS per independent radiology committee. The study had 90% power to detect a 78% PFS improvement from 5.5 mo with sorafenib to 9.8 mo with axitinib, corresponding to a hazard ratio (HR) of 0.561 (overall 1-sided α=0.025). Results: Patients (N=288) were mainly from Eastern Europe (51%), Asia (25%), North America (14%), or South America (10%).Patient baseline characteristics for axitinib (n=192) vs sorafenib (n=96) included: median age, 58y vs 58y; male, 70% vs 77%; white, 71% vs 69%; favorable risk, 49% vs 55%; PS 0, 57% vs 57%; nephrectomy, 85% vs 90%. Median (m) PFS was 10.1 vs 6.5 mo with axitinib vs sorafenib (HR adjusted for PS, 0.767; 95% confidence interval [CI], 0.559–1.053; 1‑sided P=0.0377). In patients with PS 0 and 1, respectively, mPFS with axitinib vs sorafenib was 13.7 vs 6.6 mo (HR, 0.644; 95% CI, 0.419–0.991; 1‑sided P=0.022) and 6.5 vs 6.4 mo (HR, 0.931; 95% CI, 0.585–1.482; 1‑sided P=0.38). Objective response rates (ORRs) with axitinib vs sorafenib were 32.3% vs 14.6% (1‑sided P=0.0006 adjusted for PS). Overall survival data were not mature. All-grade all‑causality adverse events (≥20%) with axitinib vs sorafenib were diarrhea (50% vs 40%), hypertension (49% vs 29%), weight decreased (37% vs 24%), fatigue (33% vs 26%), decreased appetite (29% vs 19%), palmar-plantar erythrodysesthesia (26% vs 39%), dysphonia (23% vs 10%), asthenia (21% vs 16%), and hypothyroidism (21% vs 7%). Conclusions: The study did not achieve its primary endpoint statistically, but axitinib demonstrated numerically longer mPFS and significantly higher ORR vs sorafenib, with an acceptable safety profile, as first-line therapy for mRCC. Clinical trial information: NCT00920816.

Intrahepatic Cholangiocellular Carcinoma

e15629 Background: Systemic cisplatin plus gemcitabine (CisGem) is the standard treatment for patients with advanced or metastatic intrahepatic cholangiocellular carcinoma (ICC). Transarterial chemoembolization (TACE) is a treatment procedure for patients with liver cancer. This prospective study was to evaluate the safety and efficacy of cisplatin-based TACE combined with systemic CisGem in patients with ICC. Methods: Eligibility criteria were histologically or cytologically confirmed, unresectable, recurrent or metastatic mass-forming type ICC; Eastern Cooperative Oncology Group performance status 0–2; and an adequate major organ function. Patients may have had prior treatment, including surgery, but no prior CisGem therapy. Cisplatin (25 mg/m2) plus gemcitabine (1000 mg/m2) were intravenously administered on days 1 and 8 of a 21-day cycle for 12 cycles. Three sessions of TACE were scheduled—before first, fifth, and ninth cycle of CisGem. A suspension of CDDP-powder 35 mg/m2 and lipiodol was injected through tumor-feeding branch of intrahepatic lesions, and embolization of the feeding arteries was performed using gelatin sponge (UMIN000004776). Results: Of 14 patients enrolled between December 2010 and December 2013, 7 (50%) completed treatment schedule, whereas 4 (29%) and 3 (21%) discontinued due to disease progression and adverse events (one patients each due to allergic reaction, platelet count reduction, and hepatic infection), respectively. The most common severe adverse events were elevated aspartate aminotransferase (86%) and alanine aminotransferase (71%) levels; reduced neutrophil (36%), platelet (36%), and white blood cell (28%) counts; and hepatic infection (21%). Eleven patients (79%) were evaluated for objective response (RECIST version 1.1): 9 were observed to have a partial response and 2 had a stable disease. The 6-month progression-free survival rate was 64%, and median overall survival was 25.8 months. Conclusions: Cisplatin-based TACE combined with CisGem is a feasible treatment option; however, a randomized clinical trial for comparison with CisGem is required in future. Clinical trial information: UMIN000004776.

6012 Background: EAGLE is a phase 3 study evaluating efficacy of D (anti-PD-L1 mAb) monotherapy and D+T (anti-CTLA-4 mAb) vs standard of care (SOC) in pts with R/M HNSCC who progressed following platinum-based therapy (NCT02369874). Methods: Pts were randomized 1:1:1 to D 10 mg/kg IV every 2 weeks (Q2W), D+T (D 20 mg/kg IV Q4W + T 1 mg/kg IV Q4W for 4 doses, then D 10 mg/kg IV Q2W), or SOC (investigator’s choice: cetuximab, taxane, methotrexate, or fluoropyrimidine-based regimen). The primary endpoint was overall survival (OS) with dual primary objectives of D+T vs SOC and D vs SOC. Additional endpoints included objective response rate (ORR), duration of response (DoR), and adverse events (AEs). Results: 240 pts were randomized to D, 247 to D+T and 249 to SOC. An imbalance for Eastern Cooperative Oncology Group performance status (ECOG PS) was seen in favor of the SOC arm (D, PS 0 = 26%, PS 1 = 74%; D+T, PS 0 = 26%, PS 1 = 74%; SOC, PS 0 = 32%, PS 1 = 68%). The risk of death was not statistically significantly different for D compared with SOC (HR: 0.88; 95% CI: 0.72–1.08; P = 0.20) or D+T vs SOC (HR: 1.04; 95% CI: 0.85–1.26; P = 0.76). Efficacy data are provided in the table. Treatment-related AEs Grade ≥3 were reported in 10.1% of pts (regardless of causality Grade ≥3 AEs were 41.4%) in the D arm, 16.3% (51.2%) for D+T, and 24.2% (44.2%) for SOC. Following treatment, 2% of pts in D, 5% in D+T and 15% in SOC received immunotherapy. Conclusions: D and D+T did not demonstrate a statistically significant improvement in OS compared to standard chemotherapy in pts with R/M HNSCC. Median OS and ORR of D arm were similar to other studies with checkpoint inhibitors. The SOC arm outperformed what has been seen for SOC arms in previous studies; subsequent immunotherapy may have confounded the OS analyses. The safety profile for D and D + T in R/M HNSCC is consistent with previous trials. Clinical trial information: NCT02369874. [Table: see text]

6081 Background: In SELECT, lenvatinib significantly improved progression-free survival (PFS) of pts with RR-DTC versus placebo (18.3 v 3.6 months; hazard ratio [HR]: 0.21 [99% CI: 0.14, 0.31]; P<0.001). Here we examine the treatment of RR-DTC with lenvatinib in relation to tumor size (sum of all targeted lesions) and ECOG PS. Methods: In this post hoc analysis of SELECT with pts randomized to receive lenvatinib, Kaplan-Meier estimates of time to ECOG PS ≥2 were calculated for subgroups of pts according to baseline ECOG PS or tumor size. Objective response rate (ORR) and Kaplan-Meier estimates of overall survival (OS) and PFS according to ECOG PS (0 or 1) at baseline were calculated. Correlations between ECOG PS at baseline (0 or 1) and maximum tumor shrinkage were calculated using one-way analysis of variance. Results: Pts with ECOG PS 0 or 1 at baseline had similar demographic and disease characteristics. ORR was 78.5% and 51.0% for pts with ECOG PS 0 and 1 at baseline, respectively (odds ratio [95% CI]: 3.508 [2.018, 6.097]). Mean maximum percent decrease in tumor size was significantly greater in pts with baseline ECOG PS 0 (-46.13%) versus pts with ECOG PS 1 (-37.16%; P=0.0017). For pts with ECOG PS 1 at baseline, time to ECOG PS ≥2 was numerically shorter with tumor size >60 mm versus tumor size ≤60 mm (HR [95% CI]: 1.450 [0.708, 2.967]). Additional results are summarized in the table. Conclusions: Among pts with RR-DTC, PFS, OS, ORR, and time to ECOG ≥2 were generally better for patients with lower ECOG PS or smaller tumor size at baseline. These results may indicate that it is beneficial to start lenvatinib in pts with RR-DTC early, before ECOG PS worsens and tumor size increases. Clinical trial information: NCT01321554.
