BackgroundTreatment for recurrent glioblastoma is poor, and there is a need for better therapies. Here we retrospectively assessed the efficacy and toxicity of temozolomide plus apatinib, an oral small-molecule tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor 2 in recurrent glioblastoma.Materials and MethodsA retrospective analysis of patients with recurrent glioblastoma who underwent apatinib plus temozolomide treatment was performed. Apatinib was given at 500 mg once daily. Temozolomide was administered at 200 mg/m2/d on days 1–5 or 50 mg/m2/d continuous daily according to whether they had experienced temozolomide maintenance treatment before. The main clinical data collected included tumor characteristics, status of MGMT promoter, and IDH mutation, number of relapse, response, survival, adverse reactions, and salvage therapies.ResultsFrom April 2016 to August 2019, thirty-one patients were identified. The objective response rate was 26.3%, and the disease control rate was 84.2%. The progression-free survival (PFS) at 6 months and overall survival (OS) at 12 months were 44.6 and 30.2%. The median PFS and OS were 4.9 and 8.2 months, respectively. Two patients achieved long PFS of 30.9 and 38.7+ months. The median survival time after progression of the patients with or without salvage bevacizumab was 5.1 versus 1.2 months. The most common grade 3 or 4 toxicities were hypertension (5.8%), decreased appetite (5.8%), and thrombocytopenia (4.3%), most of which were resolved after symptomatic treatment or dose reduction.ConclusionApatinib plus temozolomide is an effective salvage regimen with manageable toxicities for recurrent glioblastoma and could not reduce the sensitivity to bevacizumab.

72^ Background: Gastric cancer (GC) is the second leading cause of cancer death in Japan as well as globally. Effective treatment of GC remains a therapeutic challenge. Although in the AVAGAST trial, bevacizumab was found to offer no survival benefit. Angiogenesis continues to be the standard treatment for GC, and thus, clinical trials on many anti-angiogenic drugs have been conducted. TSU-68 (orantinib) is an oral, angiokinase inhibitor targeting the vascular endothelial growth factor receptor 2, platelet-derived growth factor receptor β, and fibroblast growth factor receptor 1. The present study evaluated the progression-free survival (PFS) and pharmacokinetics (PK) of TSU-68 in combination with Japanese standard S-1 and cisplatin (S-1/CDDP) in patients with advanced GC. Methods: In this open-label, multicenter, randomized, controlled, parallel-group, phase II trial, patients were randomized to Arm A (S-1/CDDP) or Arm B (TSU-68 plus S-1/CDDP). All patients received oral S-1 (40-60 mg/m2) twice daily for 21 days followed by a 14 day rest plus intravenous CDDP (60 mg/m2) on Day 8, repeated every 35 days. In Arm B pts received oral TSU-68 (400 mg/dose) alone, twice daily by addition 35 days. The primary endpoint was PFS. Results: In total, 93 patients were enrolled. For Arm A [male:female ratio], n=47 [35:11]; Arm B, n=45 [30:15]; the respective median age was 63.5 and 62.0 years. The median PFS was 7.0 and 6.8 months in Arms A and B, respectively (HR, 1.23; 95%CI, 0.74 to 2.05; P=0.425); the respective response rates were 56.5% and 62.2%. The most common grade 3/4 toxicities were neutropenia (Arms A and B, 34.8% and 31.1%) and hemoglobin (Arms A and B, 26.1% and 48.9%). There were no differences in other toxicities between the 2 arms, both treatments were tolerated, and no treatment-related deaths were observed. In the PK study, although Arm B had a significantly lower plasma exposure to FT, CDHP, and Oxo compared to Arm A, the exposure to 5-FU was not different between the 2 arms. The exposure to CDDP in Arm B was significantly but slightly lower than that in arm A. Conclusions: Thus,TSU-68 plus S-1/CDDP therapy did not prolong PFS of patients with advanced GC as compared with S-1/CDDP. Clinical trial information: JapicCTI-101327.

95 Background: The treatment option for ESCC patients (pts) progressing after chemotherapy is still uncertain. Anlotinib is a multi-target tyrosine kinase inhibitor involved in tumor angiogenesis and growth, such as vascular endothelia growth factor receptor (VEGFR) 2/3, etc. Methods: Eligible pts were advanced ESCC who had progressed after platinum or taxane containing chemotherapy. Between January 6, 2016 and May 22, 2018, a total of 165 pts from 13 centers in China were randomly assigned (in a 2:1 ratio) to anlotinib arm (n=110), and placebo arm (n=55). Pts were given anlotinib (12 mg/day) or placebo orally from day 1 to day 14 in a 21-day cycle until disease progression or had unacceptable toxic effects. The primary end point was progression-free survival (PFS). Results: Median PFS was 3.0 months with anlotinib and 1.4 months with placebo (HR 0.5, 95% CI, 0.3-0.7; P<0.0001). Complete response occured in 2 pts with anlotinib and 0 pt with placebo. The objective response rates were 7% in the anlotinib group and 4% in the placebo group (P=0.498), and the disease control rates (DCR) were 64% and 18%, respectively (P<0.0001). In anlotinib arm, median duration of response was 5.8 months (range, 3.1-19.7+). Grade 3/4 treatment-related adverse events (TRAE) were reported in 36.7% and 11.0% of the two group pts, and grade 5 TRAE were 2.8% and 0%, respectively. The most common grade 3/4 TRAE (>5%) in anlotinib arm were hypertension (15.6%) and loss of appetite (5.5%). Median overall survival were similar between the groups (6.1 months vs 7.2 months; HR 1.2, 95%CI 0.8-1.8, P=0.4261). The ratio of pts received post study treatments was 41.2% (40/97) in anlotinib arm and 72.7% (40/55) in placebo arm (P=0.0002), including chemotherapy (23.7% vs 54.6%), PD-1 inhibitors (4.1% vs 11.0%), and Apatinib, a VEGFR inhibitor, (10.3% vs 20.0%), etc. Conclusions: In pretreated advanced ESCC pts, anlotinib significantly improved PFS and DCR compared with placebo, with a manageable safety profile. Clinical trial information: NCT02649361.

PURPOSE Camrelizumab is an antibody against programmed death protein 1. We assessed the activity and safety of camrelizumab plus apatinib, a tyrosine kinase inhibitor of vascular endothelial growth factor receptor-2, in patients with advanced cervical cancer. METHODS This multicenter, open-label, single-arm, phase II study enrolled patients with advanced cervical cancer who progressed after at least one line of systemic therapy. Patients received camrelizumab 200 mg every 2 weeks and apatinib 250 mg once per day. The primary end point was objective response rate (ORR) assessed by investigators per RECIST version 1.1. Key secondary end points were progression-free survival (PFS), overall survival (OS), duration of response, and safety. RESULTS Forty-five patients were enrolled and received treatment. Median age was 51.0 years (range, 33-67 years), and 57.8% of patients had previously received two or more lines of chemotherapy for recurrent or metastatic disease. Ten patients (22.2%) had received bevacizumab. Median follow-up was 11.3 months (range, 1.0-15.5 months). ORR was 55.6% (95% CI, 40.0% to 70.4%), with two complete and 23 partial responses. Median PFS was 8.8 months (95% CI, 5.6 months to not estimable). Median duration of response and median OS were not reached. Treatment-related grade 3 or 4 adverse events (AEs) occurred in 71.1% of patients, and the most common AEs were hypertension (24.4%), anemia (20.0%), and fatigue (15.6%). The most common potential immune-related AEs included grade 1-2 hypothyroidism (22.2%) and reactive cutaneous capillary endothelial proliferation (8.9%). CONCLUSION Camrelizumab plus apatinib had promising antitumor activity and manageable toxicities in patients with advanced cervical cancer. Larger randomized controlled trials are warranted to validate our findings.

2039 Background: STUPP regimen is now the standard treatment for newly diagnosed GBM, while the effectiveness is limited. This study assessed the efficacy and safety of anlotinib, a multitarget tyrosine kinase inhibitor, combined with the STUPP regimen in treating these patients. Methods: This is a phase II, multicenter, open-label, single-arm trial (NCT04119674). Thirty-three patients (17 males and 16 females) were enrolled from 8 hospitals in China between January 2019 and February 2021. Inclusion criterion included 1) newly diagnosed histologically confirmed glioblastoma (WHO grade IV), 2) 2-6 weeks (wks) after surgery with healed incision, 3) 18-70 years old, 4) KPS≥60, 5) at least one measurable lesion according to RANO criteria, 6) radiotherapy (RT), chemotherapy, immunotherapy or biotherapy naïve. All patients received 54-60 Gy radiation (1.8-2.0 Gy per fraction, five days per week) concurrently with temozolomide (TMZ, 75mg/m2, orally, QD) and anlotinib (8mg, orally, QD, d1-14/3wks). Adjuvant therapy started four weeks after RT completion, including six cycles of TMZ (150-200mg/m², orally, d1-5/4wks) and eight cycles of anlotinib (8mg, orally, QD, d1-14/3wks). Patients who completed adjuvant therapy were administrated anlotinib continuously until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival (PFS). Safety assessment was done in patients who received at least one dose of study agent. Results: The median age is 52 (range 32-69) years. Analyses included data collected through February 6, 2021. The median treatment duration was 6.5 months. The median PFS was not reached, and the median overall survival (OS) was 17.4 months [95%CI 11.6-23.2]. The 1-year PFS and OS rate was 84.0% and 100.0%, respectively. Tumor response occurred in 21 patients, 63.6% (21/33) objective response (CR/PR), and 24.2% (8/33) patients had stable disease (SD).The clinical benefit rate (CBR), defined as the proportion of patients who achieved durable disease control (CR/PR/SD) more than six months, was 57.6% (19/33). Hypertension (6.1%) was the most common ≥grade 3 adverse event. No treatment related death occurred in this study through the last follow-up. Overall, toxicities are mild and manageable. Conclusions: Anlotinib combined with the STUPP regimen is efficacious and well-tolerated in newly diagnosed GBM patients. Clinical trial information: NCT04119674.

Abstract Background Preclinical data suggest sequential administration of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) following chemotherapy may improve efficacy. We hypothesized that intermittent delivery of EGFR-TKI following chemotherapy may increase efficacy. Methods This was a multicenter, single-arm phase I/II study to evaluate the efficacy of intermitted erlotinib in combination with docetaxel in patients with EGFR-negative NSCLC who failed one prior chemotherapy. The phase I primary objectives were to determine the maximum tolerated dose (MTD) and recommended dose (RD) of erlotinib. Erlotinib was administered orally once per day on days 2–16 in combination with 60 mg/m2 docetaxel on day1 for 21 days. A standard 3 + 3 dose escalation design was employed for erlotinib from 100 to 150 mg/dose. The phase II primary endpoint was the objective response rate (ORR). The ORR and 95% confidence interval (CI) were calculated using a binomial distribution. This study required 45 patients. Results In the phase I part, the planned dose escalation was completed without reaching MTD. The RD of erlotinib was determined as 150 mg/dose. In the phase II part, the ORR and disease control rate were 17.1% (95%CI: 7.2–32.1%) and 53.7% (95%CI: 37.4–69.3%), respectively. Median progression-free survival and overall survival were 3.5 (95%CI: 3.1–4.5) and 11.3 (95%CI: 8.6–16.6) months, respectively. The common non-hematological adverse event was febrile neutropenia (grade 3–4:19.6%). Two treatment-related deaths were occurred because of interstitial lung disease and pleural infection. Conclusions Intermittent dosing of erlotinib plus docetaxel is clinically feasible in phase I part but did not significantly improve ORR in phase II part.

Purpose Sorafenib and lenvatinib are oral multikinase inhibitors targeting vascular endothelial growth factor receptor (VEGFR) and approved for radioiodine (RAI)-refractory differentiated thyroid cancer (DTC). However, there are no approved second- or third-line therapies. MET is implicated in resistance to VEGFR inhibitors. Cabozantinib is an oral multikinase inhibitor targeting MET in addition to VEGFR and is approved for medullary thyroid cancer. In a phase I study of cabozantinib, five of eight patients with DTC previously treated with a VEGFR-targeted therapy had an objective response to cabozantinib. Patients and Methods Patients with RAI-refractory disease with Response Evaluation Criteria in Solid Tumor (RECIST) measurable disease and evidence of progression on prior VEGFR-targeted therapy were enrolled in this single-arm phase II study. The cabozantinib starting dose was 60 mg/day orally but could be escalated to 80 mg if the patient did not experience a response. Patients underwent tumor assessment according to RECIST v1.1 every 8 weeks. In this study, if at least five of 25 response-evaluable patients had an objective response, cabozantinib would be considered a promising agent in this patient population. Results Twenty-five patients were enrolled. The median age was 64 years, and 64% of patients were men. Twenty-one patients had received only one prior VEGFR-targeted therapy (sorafenib, pazopanib, or cediranib), and four patients had received two such therapies. The most common treatment-related adverse events were fatigue, weight loss, diarrhea, palmar-plantar erythrodysesthesia, and hypertension. One drug-related death was noted. Of the 25 patients, 10 (40%) had a partial response, 13 (52%) had stable disease, and two (8%) had nonevaluable disease. The median progression-free survival and overall survival were 12.7 months and 34.7 months, respectively. Conclusion Cabozantinib demonstrated clinically significant, durable objective response activity in patients with RAI-refractory DTC who experienced disease progression while taking prior VEGFR-targeted therapy.

1074 Background: TQB2450 is a humanized monoclonal antibody targeting programmed death-ligand 1 (PD-L1). Anlotinib is an antiangiogenic small molecule, multi-target tyrosine kinase inhibitor that has improved clinical outcomes in various solid tumors. This phase 1b study aims to evaluate the safety and efficacy of TQB2450 plus anlotinib for patients with advanced triple-negative breast cancer (TNBC) after the failure of standard therapy. Methods: This ongoing study included a dose-escalation phase and an expansion phase. Advanced TNBC patients with prior anthracyclines and/or taxanes treatment and failed at least first-line therapy were enrolled. In the dose-escalation phase, eligible patients received anlotinib (8mg, 10mg, and 12mg, qd, days 1-14; 21 days per cycle) plus TQB2450 (1200mg, day 1; 21 days per cycle) following the conventional 3+3 design. If the starting dose of 10mg anlotinib led to ≥2 dose-limiting toxicities (DLTs), 8mg anlotinib would be administered. After the dose-escalating phase, eligible patients were enrolled into the expansion cohort. The primary endpoint was objective response rate (ORR), and the secondary endpoints were overall survival (OS), disease control rate (DCR), progression-free survival (PFS), and safety. Results: Between May 29, 2019, and December 31, 2020, in the dose-escalation phase, three patients receiving 10mg anlotinib plus 1200mg TQB2450 had no DLTs in the first cycle, neither did three patients with 12mg anlotinib plus TQB2450. Next, 28 patients with advanced TNBC received 12 mg anlotinib plus TQB2450 in the expansion phase. Finally, a total of 34 patients were included with median age of 49.5 (32-70) and median prior lines of 2 (1-6). Numbers of patients with prior platinum therapy: 16, prior anthracycline therapy: 32. The ORR was 26.47% (9/34) and DCR was 82.35% (28/34). The median PFS was 8.57 months. Seventeen patients experienced grade 3 treatment-related AEs (TRAEs). Most frequently occurring (>5%) grade 3 TRAEs were QT interval prolongation (17.65%), hypertension (14.71%), diarrhea (8.82%), hand-foot syndrome (HFS) (8.82%), and hypertriglyceridemia (5.88%). Conclusions: TQB2450 plus anlotinib showed an acceptable safety profile with promising activity for previously anthracyclines and/or taxanes-treated advanced TNBC patients. Clinical trial information: NCT03855358 .[Table: see text]

e16567 Background: ICI/TKI combinations are a new standard of care for the initial treatment (tx) of mRCC. Efficacy and toxicity of such combination regimens beyond the first-line (1L) setting remain unknown. Methods: We retrospectively reviewed charts for adult patients (pts) receiving an ICI/TKI combination in any line of tx for mRCC of any histology at one of two academic centers as of May 1, 2020. ICIs included pembrolizumab (Pm), nivolumab (Ni), ipilimumab (Ip), or avelumab (Av); TKIs included sunitinib (Su), axitinib (Ax), pazopanib (Pz), lenvatinib (Ln), or cabozantinib (Ca). Clinical data including pt demographics, histology, International mRCC Database Consortium (IMDC) risk group, tx history, and ICI/TKI tx and toxicity details were recorded. Outcomes included objective response rate (ORR), median progression-free survival (mPFS), and safety, analyzed via descriptive statistics and the Kaplan-Meier method. Results: Of 85 pts, 69 (81%) were male and 67 (79%) had clear cell histology. IMDC risk was favorable (24%), intermediate (54%), poor (20%), and unknown (2%). 39% had ICI/TKI tx in the 1L setting. ICI/TKI regimens included Pm/Ax (33%), Ni/Ca (25%), Ni/Ax (20%), Av/Ax (11%), Ni/Ip/Ca (8%), Ni/Su (2%), and Ni/Ln (1%). ORR and mPFS stratified by line of tx and prior tx are shown in the table. Of 52 pts who received ICI/TKI tx as salvage (after 1L), 52% had a grade 3 or higher (≥G3) adverse event (AE), of which the most common were anorexia (13.5%), diarrhea and hypertension (11.5% each), and fatigue (9.6%). 65% of pts on salvage ICI/TKI tx stopped tx for progression/death, while 16% stopped tx for ≥G3 AE. ≥G3 AE rates by line of tx were 62.5% (2L), 50% (3L), and 45% (≥4L). Conclusions: ICI/TKI combination therapy is effective and safe beyond the 1L setting. Prior tx history appears to impact efficacy but has less of an effect on safety/tolerability. These observations will need to be confirmed in prospective studies.[Table: see text]

2035 Background: Anti-vascular endothelial growth factor (VEGF) agents are hypothesized to work synergistically with chemotherapy and radiation (RT). Vatalanib (MW 347, T1/2 4.6 h) is an oral, pan-VEGFR tyrosine kinase inhibitor that has shown activity in patients with recurrent glioblastoma. Methods: This phase I study was designed to determine the maximal tolerated dose of vatalanib in combination with RT and TMZ for patients with newly diagnosed GBM who were taking enzyme-inducing anti-epileptic drugs. RT and TMZ were administered at standard doses. Vatalanib was initiated 5 days prior to the start of RT and continued daily until tumor progression, unacceptable toxicity or a maximum of up to 12 cycles of post-RT TMZ. Cohorts of 3 patients were treated during RT and TMZ at doses of 250mg daily, 250mg BID, or 500mg BID of vatalanib. Following the completion of RT, patients were treated with vatalanib 750mg BID for the remainder of the study. Results: Nineteen patients were enrolled of which 17 took 5 or more days of vatalanib (1 patient withdrew consent prior to start of vatalanib and 1 withdrew consent after only 1 dose). The median age was 58 and the median KPS was 90. Eight patients had a diagnostic biopsy only. The MTD has not been reached. Potentially related grade 3–4 toxicities included elevated transaminases (2 patients), thrombocytopenia (1 patient), leukopenia (1 patient), neutropenia (1 patient), depressed level of consciousness (1 patient), and fatigue (1 patient). Only 1 patient suffered an asymptomatic intracerebral hemorrhage and no patient experienced wound dehiscence or infection. Five patients remain on vatalanib and the median follow-up for all patients is 6.5 months. Seven patients have died. The best responses for the 13 patients who completed combination RT/TMZ/vatalanib was 2 PR, 7 SD, and 2 PD. Two patients were clinically stable with biopsy proven pseudoprogression. Median PFS is 18.4+ months and OS has not been reached. Conclusions: Vatalanib is safe and well tolerated when added to standard RT and TMZ. The MTD has not been reached and dose escalation continues in this population of patients on enzyme inducing anti-epileptic drugs. [Table: see text]

5576 Background: Endometrial cancer (EC) is the most common gynecologic malignancy. Vascular endothelial growth factor (VEGF) overexpression in EC correlates with poor outcome, thus targeting VEGF is a rational therapeutic approach. We have conducted a two-stage open-label phase II study in advanced EC with sunitinib, an oral tyrosine kinase inhibitor of multiple VEGF receptors. Methods: Eligible pts have recurrent or metastatic EC and have received up to 1 prior chemotherapy (CT) regimen for metastatic disease. Sunitinib is given at 50 mg daily (OD) for 4 consecutive weeks (wks) followed by 2 wks off. Dose could be reduced to 37.5 mg OD and then 25 mg OD in the setting of toxicity. Imaging is repeated every 12 wks. Primary objectives are objective response rate (ORR by RECIST) and rate of 6-month progression-free survival (PFS). If 1 or more responses occur in the first 15 evaluable pts, the study would continue to a second stage (total = 30 pts). Secondary objectives are time to progression (TTP), overall survival (OS), and safety. Results: We report the results of the first stage of this study. Sixteen pts have been treated (median age: 63; range 41–74) with 37 cycles of sunitinib (median 2; range: 1–7). Baseline ECOG PS was 0 (7 pts), 1 (8 pts), or 2 (1 pt). Histology was endometrioid (7 pts), serous (5 pts), clear cell (1 pt), or mixed/other (3 pts). Most pts had high-grade histology (G3: 8; G2: 4; G1: 2; GX: 2). Nine pts had prior adjuvant CT, 8 pts had 1 prior CT for advanced EC, 4 pts had prior hormones and 7 pts had prior radiotherapy. Partial response was achieved by 2 pts (ORR = 12.5%), and 2 other pts had a best response of stable disease; 3 of these pts remained progression-free > 6 months. Median TTP = 2.5 months (95% CI: 2.47-NR), and median OS = 6.2 months (95% CI: 5.1-NR). Grade 3/4 adverse events (AE) in >10% of pts were fatigue (7 pts, 44%) and hypertension (5 pts, 31%). Dose reduction was required for 11 of 16 pts (69%). Two pts were inevaluable after receiving <2 cycles due to AE (grade 4 hyponatremia; grade 3 fatigue) and 1 other pt has yet to complete 2 cycles. Conclusions: Sunitinib shows preliminary activity in EC. This trial will proceed to a second stage of accrual to further explore the efficacy and safety of sunitinib in advanced EC.
