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.

4504 Background: Treatment options for metastatic NET, including islet cell carcinoma (ICC) and carcinoid tumor (CT), are limited. These tumors frequently express vascular endothelial growth factor receptor-2 (VEGFR-2) and platelet derived growth factor receptor receptor-β (PDGFR-β). Sorafenib, a small-molecule inhibitor of the VEGFR-2 and PDGFR-β tyrosine kinase domains, is a rational targeted therapy to evaluate in NET. Methods: Eligibility criteria included: ECOG PS = 2, = 1 prior chemotherapy, good organ function and signed informed consent. Prior interferon and prior or concurrent octreotide at a stable dose were allowed. Pts unable to take oral medications, with uncontrolled hypertension or with symptomatic coronary artery disease were excluded. Pts received sorafenib 400 mg po BID. Primary endpoint was response by RECIST in two cohorts (ie, CT and ICC) using separate 2-stage phase II designs. Results: 93 pts were enrolled: (50 CT, 43 ICC). For pts evaluable for the primary endpoint, 4 of 41 (10%) CT pts and 4 of 41 (10%) ICC pts had a PR. There were 3 minor responses (MR = 20–29% decrease in sum of target lesion diameters) in CT pts and 9 MRs in ICC pts for PR+MR rate of 17% for CT pts and 32% for ICC pts. For pts evaluable, 6-month progression-free survival was observed in 8/20 CT and 14/23 ICC pts. Grade 3–4 toxicity occurred in 43% of pts, with skin (20%), GI (7%) and fatigue (9%) most common. Translational studies from tumor tissue will be presented. Conclusions: Sorafenib at 400 mg po BID has modest activity in metastatic neuroendocrine tumors, with frequent grade = 3 toxicity.

7528 Background: Therapies directed at both the epidermal growth factor receptor (EGFR) and the vascular endothelial growth factor (VEGF) pathways have been shown to improve survival in NSCLC and also have radiosensitizing properties. Methods: Pts receive Ind Cb (AUC 6), P (225 mg/m2) and B (15 mg/kg) on d1 and 22. PET scans are done pre- and post-I. On day 43, pts receive weekly Cb (AUC 2 x 7) and P (45 mg/m2 x 7) with 74 Gy (2 Gy/d) of thoracic conformal radiotherapy (TCRT). Cohort I (n=5) received B at 10 mg/kg q2wks during C therapy. Cohorts II and III (both n=5) received the same dose of B as in cohort I but also received Er at 100 mg and 150 mg po Tuesday - Friday of each week of C therapy, respectively. The primary endpoint is PFS at 1 year. All histologies are allowed including squamous (SQ) (an early stopping rule is in place for pulmonary hemorrhagic (PH) complications in SQ pts). Results: Thus far, 31 eligible PS 0–1 pts have been accrued (med age 62 yrs, range 41–74, 19 non- squamous, 12 SQ, 63% IIIA, 37% IIIB). Ind CbP + B has been well tolerated (1 gr 3 hypertension). No PH during Ind has been seen (including the 12 SQ cell pts). Response after Ind, 37% PR, 59% SD, 4% PD. Tumor volumes and PET SUVs have significantly decreased comparing pre- and post-Ind studies (p=0.0001 and p=0.0002, respectively). Cohort II has been expanded as the phase II regimen. To date, 25 of 26 (96%) pts have achieved the dose of 74 Gy (1 pt stopped at 60 Gy due to ILD). During Conc therapy, the principal toxicity has been esophagitis (53.8% gr 2, 19.2% gr 3). One grade 3 PH occurred in 1 SQ pt. One gr 5 late (> 2 mos after treatment) PH occurred in a SQ pt. Overall response rate following treatment - 68.2% (95% CI, 45–86%). The PFS at 1 year is 58% (95% CI, 34–76%) with an estmated 1-year overall survival rate of 79% (95% CI, 53–92%) which compares favorably to our historical experience. Conclusions: Preliminarily, we conclude that 1) Incorporation of B and E into this treatment paradigm appears feasible, 2) Esophagitis remains the primary toxicity, 3) Phase II accrual continues but early analysis of survival appears promising. Further details regarding the TCRT parameters and toxicity will be presented. [Table: see text]

102 Background: This phase II study aimed to investigate the safety and efficacy of XP compared to SP in the first-line treatment of HER2 negative AGC. Methods: Patients were randomly assigned to receive either SP (S-1 at 40–60 mg twice daily for 21 days plus cisplatin at 60 mg/ m2 on day 8, every 5 weeks) or XP (capecitabine 1,000 mg/m2 twice daily for 14 days plus cisplatin 80 mg/m2 on day 1, every 3 weeks). Primary endpoint was response rate (RR), and secondary endpoints were progression-free survival (PFS), overall survival (OS), time to treatment failure (TTF), and adverse events. Results: 84 eligible patients were randomly assigned to receive SP ( N = 41) or XP ( N = 43). No statistical difference was observed in overall RR between the SP and XP groups [51.2% (95% CI, 35.1% to 67.1%) vs. 53.5% (95% CI, 37.7% to 68.8%), P = 1.000]. Despite not significant, however, SP vs. XP showed a trend toward better PFS [median, 5.9 months vs. 4.1 months; hazard ratio (HR), 0.763; 95% CI, 0.462 to 1.259; P = .284] and OS (median, 13.5 months vs. 10.0 months; HR, 0.776; 95% CI, 0.485 to 1.244; P = .290). This trend in the SP vs. XP comparison was more pronounced in TTF (median, 4.5 months vs. 3.1 months; HR, 0.651; 95% CI, 0.421 to 1.006; P = .052). Common grade 3 to 4 hematological toxicities were neutropenia and anemia (SP group, 23% and 23%; XP group, 35% and 28%). Grade 3-4 anorexia and hyponatremia were more frequently seen in the XP group (31% and 16%) compared to the SP group (13% and 5%). Treatment-related deaths occurred in one patient (2.3%) in the XP group. Conclusions: XP failed to demonstrate the superior efficacy over SP. Higher incidence of severe toxicities by XP suggests SP as the standard 1st line chemotherapy for HER2 negative AGC in Japan. Clinical trial information: UMIN000006755.

3545 Background: Cytotoxic chemotherapy with targeted therapy against the vascular endothelial growth factor (VEGF) or the epidermal growth factor receptor (EGFR) has become a standard approach in MCRC, though combining VEGF and EGFR inhibition with chemotherapy as initial treatment is not well established. We conducted a phase II study of the combination of infusional 5-fluorouracil (5-FU), leucovorin, oxaliplatin (FOLFOX), bevacizumab, and erlotinib in chemotherapy naïve patients with MCRC. Methods: Eligible patients had measurable MCRC, no prior systemic therapy for MCRC or at least one year since completion of adjuvant therapy (only 5-FU and leucovorin acceptable), performance status 0–1. The regimen consisted of 14-day cycles of FOLFOX started on day 1 (oxaliplatin 85 mg/m2, bolus 5-FU 400 mg/m2, leucovorin 400 mg/m2 and 46-hour infusion 5-FU 2.4 g/m2), day 1 bevacizumab 5 mg/kg and erlotinib 150 mg daily. This isa single stage trial with goal of 35 patients. The primary endpoint was progression-free survival (PFS). Results: Between Jan and Dec 2005, 31 patients have been enrolled with the following characteristics: male/female, 19/12; PS ECOG 0/1, 15/16; median age 58, range 38–81. Of the 28 patients who completed at least 1 cycle, the most common grade 3/4 adverse events include: 8/28 (29%) diarrhea, 8/28 (29%) neutropenia, 5/28 (18%) rash, 4/28 (14%) fatigue, 3/28 (11%) nausea/vomiting, 3/28 (11%) neuropathy. 22/28 (78%) of patients had at least 1 grade 3/4 toxicity. 14/31 patients remain on trial, 13/31 (42%) came off for toxicity or withdrew consent due to treatment-related toxicities, 4 withdrew consent for other reasons. Efficacy data is not available at time of submission but will be more mature by June 2006. Conclusions: The combination of FOLFOX, bevacizumab and erlotinib appears to have moderate toxicity, with ∼40% of patients coming off trial due to side effects. Further characterization of the tolerability profile will be necessary when interpreting the efficacy of the combination. We expect full accrual as well as reasonable point estimates of PFS by June 2006. Supported by: Sanofi-Synthelabo, a member of the Sanofi-Aventis group, Genentech [Table: see text]

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.

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.

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 Purpose The standard first-line treatment for human epidermal growth factor receptor type 2 (HER2)-positive advanced gastric cancer (AGC) is trastuzumab in combination with cisplatin and fluoropyrimidines. We evaluated the efficacy and safety of S-1 and oxaliplatin (100 mg/m2) (SOX100) combined with trastuzumab, a monoclonal antibody against HER2 for HER2-positive AGC.Methods In this single-arm, multicenter phase II study, patients with HER2-positive AGC received S-1 (80–120 mg per day) orally on days 1–14, oxaliplatin (100 mg/m2) intravenously on day 1, and trastuzumab (8 mg/kg on day 1 of the first cycle, followed by 6 mg/kg every 3 weeks) intravenously. The primary end point was 1-year survival rate. The secondary end points included overall survival (OS), progression-free survival (PFS), overall response rate (ORR), and safety. Results A total of 25 patients from six centers were enrolled from December 2015 to March 2020. In the 25 patients evaluable for analysis, the 1-year survival rate was 70.8% [90% confidence interval (CI) = 55.5%–86.1%], whereas the median OS, PFS, and ORR were 17.8 (95% CI 10.5–22.9) months, 7.6 (95% CI 5.0–10.9) months, and 75.0 (95% CI 53.3–90.2) %, respectively. Major grade 3/4 adverse events included anorexia (20%), anemia (16%), peripheral sensory neuropathy (16%), and diarrhea (15%). Conclusion SOX100 combined with trastuzumab was effective with a favorable safety profile in patients with HER2-positive AGC.

4019 Background: Targeting a single pathway in pancreatic adenocarcinoma (PAC) is unlikely to impact its natural history. EGFR targeting with erlotinib added to gemcitabine (G) marginally improved the outcome of patients with advanced disease. We tested the hypothesis that if the EGFR and IGF-1R pathways are simultaneously blocked then progression free survival (PFS) would be significantly improved by abrogating reciprocal signaling that leads to resistance to either drug. Methods: This was a phase I/randomized phase II (RP2) study testing the anti-IGF-1R monoclonal antibody cixutumumab combined with erlotinib and G in patients with metastatic PAC. The control arm was erlotinib plus G. The primary endpoint of the RP2 portion of the study was PFS. Eligibility included patients with untreated metastatic disease, performance status 0/1, fasting blood glucose less than institutional upper limit of normal, and willingness to provide tissue and blood specimens for correlative studies. Results: In phase I portion (n=10) safety of cixutumumab 6 mg/kg IV/wk, erlotinib 100 mg/day orally and G 1000 mg/m2 IV D 1, 8, and 15 of a 28-day cycle was established. In the RP2 portion (n=124) 114 eligible patients (median age 63) were included. On the cixutumumab arm, 59% of patients were female vs. 40% on control arm. Median PFS and overall survival were 3.7 and 6.7 months, respectively, in both arms of the study. Major grade 3 and 4 toxicities were (cixutumumab/control) elevation of transaminases (12%/6%), fatigue (16%/12%), gastrointestinal (35%/28%), neutropenia (21%/10%), and thrombocytopenia (16%/7%). Grade 3/4 hyperglycemia was seen in 16% of patients on cixutumumab. Grade 3 or 4 kin toxicity was similar in both arms of the study (< 5%). Five treatment-related deaths were reported: 2 cardiac on each arm, 1 pulmonary on cixutumumab. Conclusions: IGF-1R inhibitor cixutumumab did not improve the progression free or overall survival of patients with metastatic PAC treated with erlotinib and G in a molecularly unselected population.

This open-label, single-arm, two-stage, Phase II study investigated the efficacy and safety of bi-weekly pemetrexed combined with irinotecan, in patients with metastatic colorectal cancer (mCRC), after first-line chemotherapy using FOLFOX regimen.Patients and methods. Patients received pemetrexed 400 mg/m²as a 10-minute intravenous infusion (with vitamin supplementation) followed by irinotecan 180 mg/m²as a 90-minute infusion on day 1 of a 14-day cycle, for a maximum of 12 cycles. The primary endpoint was response rate (RR;H0≤5%,Ha≥20%,α=0.05, power = 90%). Secondary endpoints were duration of response, progression-free survival (PFS), overall survival (OS), and toxicities.Results. Partial response was observed in six out of 44 patients enrolled in the study (RR = 13.6%). The median PFS and OS were 4.0 and 13.9 months, respectively. The most common grade 3-4 toxicities were fatigue: 20.5% of patients, neutropenia: 18.6%, diarrhea: 13.6%, elevated transaminases: 9.5%, anemia: 9.3%, and vomiting: 6.8%.Conclusion. Pemetrexed plus irinotecan administered every two weeks is an active and well-tolerated regimen in mCRC patients pretreated with FOLFOX regimen. However, this regimen does not seem to provide clinically relevant advantage over historical data of a classical FOLFIRI regimen.
