TPS175 Background: Patients with esophageal cancer refractory to multiple treatments have poor outcomes. We assessed the activity of nivolumab, a human monoclonal IgG4 PD-1 immune checkpoint inhibitor antibody, for patients with advanced esophageal cancer. We conducted phase II, single-arm, multi-center trial in JAPAN (JapicCTI-No.142422).Methods: The target population was esophageal cancer patients aged ≥ 20 years with ECOG performance status of 0 or 1, who had received one or more previous treatments and not pre-selected by PD-L1 status. Nivolumab (3 mg/kg IV Q2W) was administered to patients until observing unacceptable toxicity or disease progression assessed at 6 week intervals. The primary endpoint was the proportion of patients with a confirmed objective response assessed by independent review committee according to RECIST 1.1. Planned sample size was 60 patients (P0 = 5, P1 = 15, α = 0.025 (one-side), 1-β = 0.8). Data cutoff, 17 May 2015.Results:We enrolled 65 patients with esophageal carcinoma: median age 62.0 years (range, 49-80 years); male/female, 54/11; ECOG PS 0/1, 29/36, Histological type was squamous in all pts. The median prior regimens was 3.0 (range, 1-8); 44 patients (67.7%) were treated with prior esophagectomy and 44 patients (67.7%) with prior radiation therapy. There were 64 evaluable patients for efficacy, and 11(17.2%) of 64 patients had objective response (CR/PR, 1/10). 16 (25.0%) of 64 patients had stable disease. The median overall survival was 12.1 months in 64 evaluable patients. The incidence of drug-related Serious AEs was 11 events (9/65 patients): Lung infection(2[3.1%]), Dehydration(2[3.1%]), Interstitial lung disease (2[3.1%]), etc. The patients with grade 3 pneumonitis improved with supportive care. There was no treatment-related death. We will introduce the updated efficacy and safety data of this trial. Conclusions: Nivolumab has meaningful activity and a manageable safety profile in pretreated esophageal cancer. These data support the assessment of nivolumab in randomized, controlled, phase III studies of second-line treatment. Funding: ONO Pharmaceutical CO.,LTD.

8514 Background: Ipilimumab (Ipi) alters the immune system balance by inhibiting the suppression of T-cell function. In two phase III trials, Ipi has shown an overall survival benefit alone and in combination with dacarbazine in previously treated and treatment-naïve patients (pts) with metastatic melanoma (MM), respectively. We performed a single-institution, phase II clinical trial of Ipi plus temozolomide (Tem) in pts with MM. Methods: Pts between the ages of 18 and 75 with previously untreated unresectable stage III or stage IV MM and an ECOG Performance Status of 0 to 1 were enrolled in a phase II trial of Ipi plus Tem. Induction phase consisted of Ipi 10mg/kg intravenous on Day 1 and oral Tem 200 mg/m2 on Days 1 – 4 every 3 weeks for 4 doses. Maintenance consisted of Ipi 10 mg/kg intravenous on Day 1 starting week 12 and repeated every 12 weeks and oral Tem 200 mg/m2 on Days 1 – 5 starting week 12 and repeated every 4 weeks until disease progression or unacceptable toxicity occurred. The primary endpoint was progression-free survival (PFS) rate at 6 months. Responses were evaluated using immune-related response criteria. Results: Sixty-four pts were enrolled and received at least one dose of study drug. All pts were included in the analysis. With a median follow-up of 8.5 months, the PFS rate at 6 months was 43%, exceeding the proposed rate of 30%, and the median PFS was 5.1 months. There were 10 (15.6%) confirmed complete responses and 8 (12.5%) confirmed partial responses. At the time of this analysis, median overall survival has not been reached. Immune-related adverse events (irAEs) were experienced by 88% of pts, most commonly pruritus (88%), rash (83%), diarrhea (56%), transaminitis (45%), and colitis (11%). Grade 3/4 irAEs seen in more than one patient were skin rash (11%), diarrhea (9%), pruritus (6%), and transaminitis (5%). Constipation occurred in 70% of pts and was the most common gastrointestinal (GI) toxicity. There were no GI perforations or deaths on study due to treatment. Conclusions: At a median follow-up of 8.5 months, the best overall response rate in this study is 28%. Ipi at 10 mg/kg in combination with Tem given in an induction followed by maintenance fashion is safe, well-tolerated, and efficacious in MM.

9524 Background: In the phase III CheckMate 037 study, NIVO improved the objective response rate and progression-free survival with less toxicity vs chemotherapy in patients (pts) with MEL who progressed after prior IPI treatment. We report the first efficacy and updated safety data from pts with MEL in CheckMate 172, including those with rare melanoma subtypes (uveal, mucosal), brain metastases, or an ECOG performance status (PS) of 2. Methods: In this ongoing phase II, single-arm, open-label, multicenter study, pts with MEL who progressed on or after IPI were treated with NIVO 3 mg/kg Q2W for up to 2 years until progression or unacceptable toxicity (NCT02156804). We report efficacy and updated safety data from 734 treated pts with ≥1 year of follow-up (database lock: November 2016). Results: Of 734 pts, 50% had LDH>ULN, 7% ECOG PS 2, 66% M1c disease, 15% a history of brain metastases, and 23% received ≥3 prior therapies. Overall, 593 pts (81%) received more than 4 doses of NIVO. Overall, response rate at 12 weeks was 32%, with a complete response in 1% (Table). The 1-year overall survival (OS) rate was 63%. Any grade and grade 3/4 treatment-related adverse events (AEs) occurred in 66% and 17% of pts, respectively. Discontinuations due to treatment-related AEs occurred in 4% of pts. The most common treatment-related select (potentially immune-related) AEs were diarrhea (12%), hypothyroidism (9%), and pruritus (7%). Conclusions: CheckMate 172 is the largest study of NIVO efficacy and safety in pts with MEL who progressed on or after IPI. NIVO demonstrated a safety profile consistent with that of prior clinical trials. Efficacy outcomes were encouraging in some difficult-to-treat subgroups of pts with poor prognostic factors, such as mucosal melanoma and brain metastases. Clinical trial information: NCT02156804.

446 Background: Pmab has demonstrated significant improvement in progression-free survival (PFS) in pts with WT KRAS mCRC as 1st-line tx in a phase III trial comparing pmab + FOLFOX4 vs FOLFOX4 alone. Here, we describe the results of PEAK, a multicenter, randomized phase II study evaluating pmab + mFOLFOX6 and bev + mFOLFOX6 in pts with previously untreated WT KRASmCRC. Methods: Pts were randomized 1:1 to pmab 6.0 mg/kg + mFOLFOX6 Q2W or bev 5.0 mg/kg + mFOLFOX6 Q2W. Pt eligibility criteria included: WT KRASmCRC, ECOG performance status ≤ 1, and no prior chemotherapy, anti-VEGF tx, or anti-EGFR tx for mCRC. The primary endpoint was PFS; secondary endpoints included overall survival (OS), objective response rate (ORR), and safety. No formal hypothesis was tested. Results: 285 pts with WT KRASmCRC were randomized and 278 pts received tx. Demographics were balanced between arms. Intent-to-treat efficacy results are shown (Table). Worst grade 3/4 adverse events (AE) occurred in 86% of pts in the pmab + mFOLFOX6 arm vs 76% of pts in the bev + mFOLFOX6 arm. Grade 5 AEs occurred in 5% of pts in the pmab + mFOLFOX6 arm and 6% of pts in the bev + mFOLFOX6 arm. Tx discontinuation due to any AE was 24% in the pmab + mFOLFOX6 arm and 27% in the bev + mFOLFOX6 arm. Conclusions: In this estimation study of pts with WT KRASmCRC without any prior therapy for mCRC, PFS and ORR were similar between arms. The median OS was not reached in the pmab + mFOLFOX6 arm. The safety profile for both arms was consistent with previously reported studies of either combination. Tx discontinuation rates due to AEs were similar between arms. Clinical trial information: NCT00819780. [Table: see text]

Eribulin Mesylate

TPS1140 Background: Eribulin mesylate is a nontaxane microtubule dynamics inhibitor that is approved in patients with metastatic breast cancer who have previously received at least two chemotherapeutic regimens (including an anthracycline and a taxane) for metastatic breast cancer. In a previous phase III study, eribulin mesylate demonstrated to significant improvement in overall survival in patients with heavily pretreated, locally recurrent or metastatic breast cancer when compared to treatment of physician’s choice. The majority of patients were HER2-negative and all had previously failed 2 or more regimens. Overall, the tolerability and positive phase III findings in this patient population suggest eribulin mesylate may provide a treatment advantage when given earlier in the course of therapy for HER2-negative, metastatic breast cancer. Methods: This study is phase II, multicenter, open-label, single-arm in patients with HER2-negative metastatic breast cancer who have been treated with chemotherapeutic regimens including an antheracycline and a taxane. Eribulin mesylate (1.4mg/m2) will be given on days 1 and 8 of each 21-day cycle. The primary endpoint is objective response rate, and secondary endpoints include duration of response, progression-free survival, overall survival, the safety of the treatment, and quality of life. Eligibility Criteria: Patients must have confirmed HER2-negative metastatic breast cancer with at least 4 weeks since prior neoadjuvant or adjuvant chemotherapy, and have not received over 2 chemotherapeutic regimens for metastatic disease. Additional eligibility criteria include adequate performance status (ECOG PS:0-2) and end organ/marrow function, and ejection fraction > 50%. Accrual: This study began in December 2012. The expected end of accrual of 35 patients will be the last quarter 2015.

Abstract   Esophageal squamous cell carcinoma (ESCC) as a common malignancy is prevalent in East Asia and in eastern and southern Africa. Although pembrolizumab, nivolumab and camrelizumab are respectively recommended as second-line treatment for advanced ESCC due to improved overall survival (OS), objective response rate (ORR) was modest. New effective treatments are needed. Hence, the study of camrelizumab plus apatinib (VEGFR2 inhibitor) as second-line treatment for advanced ESCC was performed. Methods This ongoing phase II trial (NCT03736863) in six sites in China enrolled pts aged 18-75 with unresectable locally advanced, locally recurrent, or metastatic ESCC that progressed or were intolerant after first-line chemotherapy, and an ECOG performance status of 0-1. Pts received 200 mg camrelizumab intravenously every 2 weeks and apatinib 250 mg orally once per day in 4-week cycles until disease progression, unacceptable adverse events (AEs) or withdrawal of consent. The primary endpoint was investigator-assessed ORR. Secondary endpoints included disease control rate (DCR), progression-free survival (PFS) and OS. Results At data cutoff (Feb 28, 2021), 52 pts were enrolled, including 42 males and 50 with distant metastases, with the median age of 62 years. In the evaluable population of 39 pts, ORR without confirmation was 43.59% and DCR was 94.87%. The median duration of response was 6.9 months (95% CI 4.57–9.23). The median PFS was 6.8 month (95% CI 2.66–10.94). The 12-month overall survival was 52.2%. A total of 80.8% of pts had treatment-related AEs (TRAEs) with 46.2% of grade ≥ 3 TRAEs. The safety profile of camrelizumab and apatinib was consistent with other anti–PD-1 antibodies and angiogenesis inhibitors. Conclusion This is the first study that evaluates the combination anti–PD-1 antibody and anti-angiogenesis inhibitor as a second-line therapy for advanced ESCC. Camrelizumab plus apatinib showed encouraging clinical efficacy and acceptable safety. Further phase III randomized trials are warranted.

This study investigated the antitumor activity and safety of pembrolizumab in patients with recurrent cervical cancer in real-world practice. We conducted a multi-center retrospective study of patients with recurrent or persistent cervical cancer treated with pembrolizumab at sixteen institutions in Korea between January 2016 and March 2020. The primary endpoints were the objective response rate (ORR) and safety. Data were available for 117 patients. The median age was 53 years (range, 28–79). Sixty-four (54.7%) patients had an Eastern Cooperative Oncology Group (ECOG) performance status of ≥2. Forty-nine (41.9%) patients were stage ≥III at diagnosis. Eighty-eight (75.2%) patients had squamous cell carcinoma. The median number of prior chemotherapy lines was two (range, 1–6). During the median follow-up of 4.9 months (range, 0.2–35.3), the ORR was 9.4%, with three complete responses and eight partial responses. The median time to response was 2.8 months (range 1.3–13.1), and the median duration of response (DOR) was not reached. In the population of patients with favorable performance status (ECOG ≤1) (n = 53), the ORR was 18.9%, and the median DOR was 8.9 months (range, 7.3–10.4). Adverse events occurred in 55 (47.0%) patients, including eight (6.8%) patients who experienced grade ≥3 events, and two of them were suspicious treatment-related deaths. Pembrolizumab had modest antitumor activity in patients with recurrent cervical cancer comparable to that found in previously reported clinical trials. However, in patients with favorable performance status, pembrolizumab showed effective antitumor activity. Some safety profiles should be carefully monitored during treatment.

7033 Background: Carboplatin/vinorelbine (CV) and carboplatin/gemcitabine (CG) are novel 2-drug combinations in the treatment of NSCLC. In a randomized national multicenter phase III study in stage IIIB and IV patients (pts), we compared these regimens with respect to efficacy, toxicity and quality of life (QoL). Methods: Chemonaive pts with histologically or cytologically proven NSCLC, stage IIIB or IV and ECOG performance status (PS) 0–2 were eligible. There was no upper age limit. Pts received vinorelbine 25 mg/m2 or gemcitabine 1000 mg/m2, both administered on day 1 and 8, in combination with carboplatin (Chatelut AUC 4) at day 1. Three courses were administered in 3-week cycles. QoL questionnaires were completed at baseline, before each cycle and then every 8 weeks up to one year. Primary endpoints were survival and QoL and secondary endpoints toxicity and time to progression (TTP). Stratification was done for age, stage and PS, and the planned sample size per arm was minimum 200. The analyses were performed on an intention-to-treat basis Results: From Oct 2003 through Dec 2004, 433 pts from 33 institutions were randomized to CV (n=218) or CG (n=215). Follow-up was minimum one year. There was no difference in overall survival between the two arms (p=0.89). Median survival was 7.3 vs. 6.5 months and 1-year survival 28% and 31% in the CV and CG arm respectively. TTP was significantly longer in the CG arm (p=0.006) with median TTP 4.2 vs. 3.9 months. There was significantly more grade 3–4 anemia and thrombocytopenia in the CG arm (p<0.001) and more grade 3–4 leucopenia in the CV arm (p= 0.001). More pts in the CG arm needed transfusions of blood (p=0.003) or platelets (p=0.001). There was no difference between the arms with respect to neutropenic infections (p=0.87). QoL data are still being analyzed and will be presented at ASCO. Conclusions: Overall survival was similar in the two treatment arms. In the CG arm, the median TTP was longer, but grade 3–4 toxicity requiring interventions, was more frequent when compared to the VC arm. No significant financial relationships to disclose.

5537 Background: The epidermal growth factor receptor (EGFR) is expressed in nearly all SCCHN and carries a strong prognostic significance, providing the rationale for using EGFR-targeted agents, such as cetuximab, in this indication. This study assesses the efficacy and safety of cetuximab in combination with chemotherapy commonly used in the treatment of R&M SCCHN. Methods: Patients (pts) were enrolled into this phase III trial from December 2004 to December 2005 and randomized either to Group A: cetuximab (first dose 400 mg/m2 then 250 mg/m2 weekly) plus a maximum of 6 three-weekly cycles of cisplatin (100 mg/m2 IV on day 1) or carboplatin (AUC 5, day 1) and 5-FU (1000 mg/m2/day continuous infusion for the first 4 days of each cycle) or to Group B: cisplatin or carboplatin with 5-FU as before. Cetuximab was administered until progression or unacceptable toxicity. Primary endpoint is overall survival time; secondary endpoints are progression-free-survival, response rate, disease control rate, safety, and Quality of Life. It was planned to randomize a total number of 420 pts in order to detect a difference in improvement in overall survival of 2.5 months. Results: At the end of the recruitment,440 pts have been randomized, to date 320 pts are under treatment, 21 have withdrawn from the study and 99 have completed the study. The Data Safety Monitoring Board (DSMB) has performed an independent preplanned safety analysis from the first 140 pts, 138 pts of whom were treated. Patients were followed for a minimum of 6 weeks: M/F122/16, median age57 years [range, 38–79],median Karnofsky performance status (KPS) 80 [range, 70–100]. In this safety analysis, there were 14 deaths, none of which were treatment related. The most frequent drug related grade 3–4 toxicity was mainly represented by neutropenia, thrombocytopenia and anemia. Conclusions: The DSMB evaluated baseline and safety data, found no reason to stop the trial and recommended continuation of the study. [Table: see text]

14599 Background: We prospectively conducted a phase II trial to test the efficacy and safety of irinotecan, 5-fluorouracil and leucovorin (FOLFIRI) regimens for the first-line treatment of previously untreated patients with recurrent or metastatic advanced CRC. Methods: Thirty-four previously untreated patients with advanced CRC were enrolled in this study from June 2001 to December 2006. Eligible patients had histologically confirmed adenocarcinoma, no prior systemic therapy in palliative setting, ECOG PS = 2, adequate organ function, written informed consent and at least one measurable disease. The patients received either irinotecan 180 mg/m2 on day 1 with a LV bolus of 200 mg/m2 and a FU bolus of 400 mg/m2, and this was followed by a FU continuous infusion of 600 mg/m2 on day 1 and day 2 (the classic FOLFIRI regimen), or they were treated with a LV bolus of 400 mg/m2 and a FU bolus of 400 mg/m2 followed by a FU continuous infusion of 2,400 mg/m2 for 46 hours (the simplified FOLFIRI regimen), and these treatments were repeated every 2 weeks until disease progression. Results: There were 13 females and 21 males with median age of 54 years (range: 41–79). The most common metastatic sites were lung and liver. A total of 262 cycles were administrated with median 6 cycles per patient (range: 1–22). All pts were evaluable for toxicity, and 30 pts for response to the treatment. The objective response rate was 26.4% with 2 complete responses respectively. Sixteen (47%) pts had stable disease and 7 (20.5%) had a progression. The tumor control rate was 73.4%. The median TTP was 5.3 months, and the overall survival was 10.1 months. The prognostic factor for longer TTP and survival was the ECOG performance status (PS). The type of regimens was not affected on response rate, TTP and survival. The chemotherapy was generally well tolerated and the most common grade 3–4 toxicities were neutropenia, diarrhea. The non- hematological toxicities were similar for both treatment groups, with more frequent grade =3 neutropenia being noted for the simplified FOLFIRI regimen. Conclusions: The FOLFIRI regimen was demonstrated to have a moderate antitumor activity with acceptable toxicity profiles, and tend to show more favorable outcome for patients with good ECOG PS. No significant financial relationships to disclose.

18011 Background: Recurrent SCLC has a poor prognosis and is devoid of treatment options that improve overall survival. Irinotecan and paclitaxel are both active agents against SCLC, and have synergistic preclinical interactions. We conducted a phase II study to evaluate the efficacy and safety of the combination of irinotecan and paclitaxel for patients with recurrent SCLC. Methods: Patients with SCLC who relapsed following one prior chemotherapy regimen were eligible. Other pertinent inclusion criteria were: ECOG performance status 0–2, adequate bone marrow, hepatic and renal function and willingness to provide informed consent. Patients with untreated brain metastasis were excluded. Paclitaxel (75 mg/m2) and irinotecan (50 mg/m2) were administered on days 1 & 8 of every 3-week cycle. Treatment was continued until progression up to a maximum of 6 cycles or unacceptable toxicity. The primary endpoint was response rate. Toxicity was graded by CTC version 2.0. The simon two-stage design was utilized and the estimated sample size was 55 patients (stage I - 23 patients; stage 2 - 32 patients). The study has a 90% power to detect a response rate of 30%, with an alpha error rate of 10%. Results: 55 patients have been enrolled and complete data are available for 32 patients at the time of this report. Patient baseline characteristics are: male 53%, PS 0–44%; PS 1–47% and PS 2–6%. The median age is 61 years. Fifteen patients received ≥ 4 cycles. Salient grades 3–5 toxicities seen: neutropenia (13%), fatigue (13%); diarrhea (3%), hypersensitivity (3%) and hyponatremia (3%).The objective response rate is 37% (95% CI 19%-55%) with 9 PRs and 1 CR. Additional 8 patients (24%) had stable disease. The median survival is 19.6 weeks (95% CI 15.1–29.4) and the 1-year survival rate is 15%. Conclusions: The combination of irinotecan and paclitaxel is well tolerated and has promising anti-cancer activity in recurrent SCLC. Updated data on all 55 patients will be available at the time of the presentation. No significant financial relationships to disclose.
