11567 Background: Combination trabectidin (T) and nivolumab (N) has been shown to be a safe and effective therapy in soft tissue sarcoma (STS). Intratumoral injection of talimogene laherparepvec (TVEC) has a local oncolytic effect, and increases immune response via enhanced recruitment of antigen presenting cells, and thereby cytotoxic immune response. This study aims to determine if the addition of TVEC to combination trabectedin and nivolumab is effective and safe in advanced sarcoma. Methods: Eligible patients include patients ≥ 18 years of age with locally advanced unresectable or metastatic STS, measurable disease by RECIST v1.1, and at least one accessible tumor for TVEC intratumoral injection. N (3 mg/kg i.v. q 2 weeks), T (1.2 mg/m2 i.v. q 3 weeks) and TVEC (1x10e8 PFU/ml q 2 weeks depending on tumor size) were administered. A test dose of TVEC (1x10e6 PFU/ml) was initially given, followed three weeks later by full dose TVEC. Primary endpoint: Progression-free survival (PFS); Secondary endpoints: (1) Best overall response during treatment period, (2) PFS rate at 6 and 9 months, (3) Overall survival (OS) rate at 6, 9, and 12 months, (4) Incidence of conversion from unresectable to resectable tumor, and (5) Incidence of treatment-related adverse events. Interim. Results: There were 36 evaluable subjects under the Modified Intention-to-Treat (MITT) population, having completed the first cycle of TNT and a CT or MRI scan at the 6-week follow-up period. The most common histological subtypes include leiomyosarcoma (9), liposarcoma (5), spindle cell sarcoma (3), pleomorphic sarcoma (2), Ewing’s sarcoma (2), and other (5). Median number of prior lines of therapy was 4 (range 1-8). Best Overall Response by RECIST v1.1 = 3 PR, 27 SD, 5 PD. One patient, with previously unresectable disease was taken for resection and was found to have 100% necrosis on surgical pathology. Disease control rate (CR+PR+SD) was 86.1%. The median PFS was 5.5 (range: 1-18) months; 6-month PFS rate: 62.1%. Median PFS on therapy immediately preceding this trial was 2.0 months (range = 1-14 months). There were 47 evaluable subjects for OS analysis under the Intention-to-Treat (ITT) population having received at least one dose of T and N. The median OS was 9.0 (range 0-20) months; 6-month OS rate: 73%. Safety analysis: There were 47 evaluable subjects under the ITT population. 28% of these patients experienced ³1 SAE. The most common grade 3/4 TRAEs include anemia (12), increased ALT (8), fatigue (4), thrombocytopenia (4), neutropenia (4). There were no grade 3/4 TVEC injection site reactions. 22% of patients in the MITT cohort remain on study. Conclusions: These results suggest that combination therapy with TNT appears to be as effective as standard therapy, with no new safety signals seen. Furthermore, median PFS exceeded that of the immediately preceding lines of therapy in this heavily pre-treated cohort. As data matures, further data will be reported. Clinical trial information: NCT03886311.

e16024 Background: Nimotuzumab is a humanized monoclonal antibody (MAb) to EGFR. Concurrent cisplatin with radical radiotherapy (RT) is standard treatment for locally advanced SCCHN where it is unresectable or for organ-preservation. We explored the combination of nimotuzumab with concurrent CDDP and RT in these patients (pts). Methods: Pts with locally advanced stage III/IV SCCHN were eligible for study if: age > 18, ECOG 0-1, SCC, normal organ function. Analysis was by intention-to-treat (ITT). CDDP 100 mg/m2 on days 1, 22, and 43 was given with RT (70 Gy over 35 fractions). Nimotuzumab was given as a flat dose of 200 mg weekly on weeks 1 to 8 of treatment. Pts were followed up for RECIST response, progression free survival and toxicity. Results: Twenty-eight pts were available for analysis at the time of report. The median age was 58 (30-69). Most were Chinese (90%) and all ECOG 0-1. Twelve pts had oropharynx Ca, 16 had non-oropharyx Ca. Twenty-five pts were evaluable for response, 2 pts withdrew consent after 2 weeks, 1 pt died of undiagnosed Fanconi anemia. By ITT, the best overall response rate (CR/PR) was 78.6% (12 CR/10 PR), SD 3.6% (1), PD 7.2% (2). Pts with oropharynx Ca had higher PFS rate at 1 year than non-oropharynx (80% vs 48%). Major grade 3/4 toxicities were limited to mucositis, dysphagia, and fatigue. Grade 5 toxicity due to febrile pancytopenia occurred in 1 pt with undiagnosed Fanconi’s. Acneiform rash typical of EGFR inhibitors occurred in 1 pt. Conclusions: Nimotuzumab with concurrent CDDP/RT is feasible and there was minimal additional toxicity encountered. Final results will be updated at the meeting.

250 Background: Cisplatin-based chemotherapy (CBC) has been widely used in trials of adjuvant therapy for LABC after RC. A high proportion of patients are unfit for CBC after RC for LABC. We therefore performed a prospective randomized phase III trial on G-monotherapy administered as adjuvant therapy (G-adj) vs in case of progression (G-prog) in pts not suitable for CBC. Methods: Between 7/2000 and 12/2008 120 of 178 planned pts with LABC unfit for CBC were randomized between 6 adjuvant cycles of G (q3w) starting within 12 wks after RC and G in case of disease progression. The primary endpoint of the trial was progression-free survival (PFS). Secondary endpoints included cancer-specific (CSS) and overall survival (OS) as well as treatment related toxicity. Results: The trial of 178 planned pts was closed early due to slow accrual. Of 120 randomized pts from 29 centers 114 were eligible for analysis. Median age of 81 male and 33 female pts was 72 (45-82) years. Lymph-node positive disease was found in 52/114 (47%) of pts at the time of surgery. The intention-to-treat analysis demonstrated a 10% difference in PFS after 3 years 50% (G-adj) vs 40% (G-prog) with a median PFS of 23 mo (G-adj) vs 17 mo (G-prog). The difference in PFS was not statistically significant (nss) (p= 0.335; HR 1.375, 95%CI 0.719 - 2.627). CSS at 3ys: 56% (G-adj) vs 50% (G-prog) with a median CSS of 49 mo (G-adj) vs 38 mo (G-prog). The difference in CSS was nss (p= 0.622; HR 1.166, 95%CI 0.632 - 2.149). OS at 3ys: 49% (G-adj) vs 48% (G-prog) with a median OS of 32 mo (G-adj) vs 31 mo (G-prog). The difference in OS was nss (p= 0.426; HR 1.225, 95%CI 0.743 - 2.018). Treatment with G was usually well tolerated, with less than 15% grade 3/4 toxicities..There was one treatment related death in the G-adj arm. Conclusions: The study-hypothesis of a 15% difference in PFS after 3 years in favor of G-adj vs G-prog could not be confirmed. Nevertheless a marked difference in survival in favor of G-adj was shown by Kaplan-Meier plots regarding PFS, CSS and OS within the first 24 months after RC. Clinical trial information: NCT00146276.

344 Background: Erlotinib is the only targeted agent in combination with gemcitabine showing significantly improved outcomes in pancreatic cancer. Although combining platinum agent with gemcitabine has not provided clear survival benefit over gemcitabine alone, gemcitabine plus platinum resulted in improved response rate and progression-free survival (PFS). We tried to evaluate whether the addition of oxaliplatin to gemcitabine/erlotinib confers a clinical benefit to patients with locally advanced or metastatic pancreatic cancer. Methods: Chemotherapy-naïve patients with locally advanced or metastatic pancreatic cancer were randomly assigned to receive GEMOX-T (gemcitabine 1000mg/m2 IV and oxaliplatin 50mg/m2 IV on day 1, 8 plus erlotinib 100mg daily, every 3weeks) or GT (gemcitabine 1000mg/m2 IV on day 1, 8 plus erlotinib 100mg daily, every 3weeks). The primary endpoint was overall response and secondary endpoints included PFS, overall survival (OS) and toxicity. Results: Between May 2013 and April 2016, 65 patients were randomly assigned to treatment group (33 in GEMOX-T arm, 32 in GT arm). The median age of all patients was 61 years (range, 41-76) and about 80% of patients had metastatic disease. The overall response rate was 18.2 % in GEMOX-T arm and 6.2% in GT arm ( P = 0.051). The disease control rate was significantly superior in GEMOX-T arm compared to GT arm (72.7% vs. 43.8%, P = 0.019), with 1 patient in GEMOX-T group continuing the treatment with stable disease. After a median follow up of 19.7 months, there was significant difference in PFS: the median PFS were 3.9 months for GEMOX-T arm and 1.4 months for GT arm (Hazard ratio: 0.58, 95% CI 0.35-0.96, P = 0.037). However, it did not translate to improvement of OS (median OS; 6.2 m for GEMOX-T arm, 5.1 m for GT arm, P = 0.118). The most common grade ≥ 3 hematologic adverse events were neutropenia (16.9%) and anemia (13.8%). Conclusions: The addition of oxaliplatin to 1st line gemcitabine/erlotinib regimen demonstrated higher response rate and significantly improved PFS in patients with locally advanced or metastatic pancreatic cancer.

PurposeTo evaluate trastuzumab (H) and docetaxel (T) with or without capecitabine (X) as first-line combination therapy for human epidermal growth factor receptor 2 (HER2) -positive advanced breast cancer.Patients and MethodsPatients with HER2-positive locally advanced or metastatic breast cancer were randomly assigned to H (8 mg/kg loading; 6 mg/kg every 3 weeks) plus T (75 mg/m2in HTX arm, 100 mg/m2in HT arm, every 3 weeks) with or without X (950 mg/m2twice per day on days 1 to 14 every 3 weeks). The primary end point was overall response rate (ORR).ResultsIn 222 patients, median follow-up was approximately 24 months. ORR was high with both regimens (70.5% with HTX; 72.7% with HT; P = .717); complete response rate was 23.2% with HTX compared with 16.4% with HT. HTX demonstrated significantly longer progression-free survival: median 17.9 months compared with 12.8 months with HT (hazard ratio, 0.72; P = .045), which translates to a gain of around 5 months. Two-year survival probability was 75% with HTX compared with 66% with HT. Febrile neutropenia (27% v 15%) and grade 3/4 neutropenia (77% v 54%) incidences were higher with HT than HTX. Treatment-related grade 3 hand-foot syndrome (17% v < 1%) and grade 3/4 diarrhea (11% v 4%) occurred more commonly with HTX than HT. One case of congestive heart failure occurred in each arm.ConclusionHTX is an effective and feasible first-line therapy for HER2-positive locally advanced or metastatic breast cancer, although it should be reserved for patients with good performance status who are not receiving long-term steroids.

Background Patients with locally advanced, recurrent or metastatic solitary fibrous tumour are often treated with bevacizumab and temozolomide based on the clinical efficacy reported in a case series of 14 patients. Given the rarity of solitary fibrous tumour, large trials are not feasible. We report the efficacy of this regimen based on a population-based analysis. Methods This was a population-based retrospective, multi-centre analysis using patient data from a provincial cancer registry and treatment database. Cases from June 2006 through October 2016 were identified for patients receiving bevacizumab and temozolomide for locally advanced, recurrent or metastatic solitary fibrous tumour or hemangiopericytoma, which is sometimes used to describe tumours arising from the meninges. The primary outcome was overall response rate. Secondary outcomes included time to response, progression free survival and overall survival estimated using the Kaplan–Meier method. Results Fourteen patients were identified: median age 59 (range 44–70), male 78.6%. Diagnoses were solitary fibrous tumour in 10 (71.4%) and hemangiopericytoma in four (28.6%), with metastatic disease in 10 (72.7%) patients. The most common primary sites were meninges in four (28.6%) and pelvis in three (21.4%) patients. The median follow-up was 15.5 months, with median treatment of four months. Overall response rate was 21.4% (no complete response, 3 partial response), with median time to response of four months. Median progression free survival, six-month progression free survival and overall survival were 17 months, 65.0%, and 45 months, respectively. Conclusions Efficacy of bevacizumab and temozolomide in solitary fibrous tumour appeared to be similar to that previously reported. Our findings confirmed that bevacizumab and temozolomide is an effective and tolerated treatment for this patient population.

LBA2 Background: Gemcitabine-cisplatin (GP) chemotherapy is the standard 1st line treatment for locally advanced, recurrent or metastatic (r/m) NPC. Toripalimab, a humanized IgG4K monoclonal antibody specific for PD-1, provided durable responses in patients (pts) with r/m NPC as monotherapy in the ≥2nd line setting (POLARIS-02 study). The results of JUPITER-02, a randomized, placebo-controlled, double-blinded Phase III trial of toripalimab in combination with GP chemotherapy as first-line treatment for r/m NPC are summarized. Methods: Pts with advanced NPC with no prior chemotherapy in the r/m setting were randomized (1:1) to receive toripalimab 240 mg or placebo d1 in combination with gemcitabine 1000 mg/m2 d1, d8 and cisplatin 80 mg/m2 d1 every 3 weeks (Q3W) for up to 6 cycles, followed by monotherapy with toripalimab or placebo Q3W until disease progression, intolerable toxicity, or completion of 2 years of treatment. Stratification factors were ECOG PS (0 vs. 1) and extent of disease (recurrent vs. primary metastatic) at enrollment. Progression-free survival (PFS) and response were assessed by independent review committee (IRC) per RECIST v1.1. The primary endpoint was PFS by IRC in the ITT population. Secondary end points included ORR, DOR and OS. There was one prespecified interim analysis of PFS at 130 PFS events with a planned final analysis at 200 PFS events. Results: 289 pts were randomized: 146 to the toripalimab arm and 143 to the placebo arm. By May 30, 2020 as the interim analysis cutoff date, the median treatment duration was 39 weeks in the toripalimab arm and 36 weeks in the placebo arm. A significant improvement in PFS was detected for the toripalimab arm compared to the placebo arm (HR = 0.52 [95% CI: 0.36-0.74] two-sided p = 0.0003), with median PFS of 11.7 vs. 8.0 months. The 1-year PFS rates were 49% and 28% respectively. An improvement in PFS was observed across relevant subgroups, including all PD-L1 subgroups. The ORR was 77.4% vs. 66.4% (P = 0.033) and the median DOR was 10.0 vs. 5.7 months (HR = 0.50 [95% CI: 0.33-0.78]). As of Jan 15, 2021, OS was not mature, with 25 deaths in the toripalimab arm and 35 in the placebo arm (HR = 0.68 [95% CI: 0.41-1.14], P = 0.14). The incidence of Grade ≥3 adverse events (AEs) (89.0% vs 89.5%); AEs leading to discontinuation of toripalimab/placebo (7.5% vs 4.9%); and fatal AEs (2.7% vs 2.8%) were similar between two arms; however, immune-related (irAEs) (39.7% vs. 18.9%) and Grade ≥3 irAEs (7.5% vs. 0.7%) were more frequent in the toripalimab arm. Conclusions: The addition of toripalimab to GP chemotherapy as 1st-line treatment for pts with advanced NPC provided superior PFS and ORR and longer DOR than GP alone with a manageable safety profile. These results support the use of toripalimab with GP chemotherapy as the new standard care for this population. Clinical trial information: NCT03581786.

15520 Background: The optimum radiosensitizing dose and schedule of gemcitabine for squamous cell carcinoma of head and neck are not known. The objectives of this study were to evaluate the efficacy and toxicity of weekly gemcitabine as a radiosensitizer concurrent with radical radiotherapy in locally advanced head and neck cancer. Method: Thirty-nine patients with stage III or IV B inoperable carcinoma of head and neck were enrolled. Eligible patients had histopathologically confirmed squamous cell carcinoma with age between 18–70 years. Patients had a KPS >70 with an adequate marrow, hepatic and renal function. No prior chemotherapy or radiotherapy was allowed. Patients with nasopharyngeal, glottic or sub-glottic cancer were excluded. Gemcitabine 150 mg/m2 or a total dose not exceeding 200 mg was given on day 1,8,15,22,29, and 36 during radiation treatment. Gemcitabine was infused in 200 ml of normal saline in 2 hours and radiation was delivered two hours after the completion of gemcitabine infusion. Conventional fractionation was used to deliver a total dose of 66 Gy. CTC version 2.0 of NCI and RTOG/EORTC Late Radiation Morbidity Scoring Scheme were used for evaluation of toxicity and RECIST was used for response evaluation. Results: Only 35 patients were considered evaluable for response. Complete response was seen in 8 (22.9%) (95% CI; 10.4–40.1%), partial response in 25 (71.4%), with an overall response rate of 94.3% (95% CI; 80.8–99.3%). All the thirty-nine patients were evaluable for toxicity. Grade 3 and 4 mucositis was seen in 28 (71.8%) and 2 (5.1%) patients respectively. Grade 3 pharyngeal toxicity was seen in 6 (15.4%). One patient developed pharyngo-cutaneous fistula. Despite vigorous symptomatic and supportive care acute toxicities led to treatment interruption in 16 (41%) of patients. Conclusion: Weekly gemcitabine at a dose of 150mg/m2 concurrent with radiation therapy gives a high overall response rate and a high rate of acute toxicity. No significant financial relationships to disclose.

4554 Background: Combination regimens of 3 drugs have shown promising activity as treatment for patients (pts) with metastatic gastric cancer (GC). Docetaxel combined with cisplatin and 5-FU (CF) improved overall survival and response rates when compared to standard CF. However, the identification of less toxic and more convenient variants of this regimen is still important. We have previously established a regimen with docetaxel (T) combined with oxaliplatin (E) and capecitabine (X) in a phase I trial [Grothe et al., Proc. ASCO 2006]. Results of a preplanned interim analysis of subsequent multicenter phase II trials of the TEX regimen are presented here. Methods: Pts with metastatic or locally advanced GC, adequate organ function, ECOG PS 0–2, and no prior chemotherapy for advanced disease (adjuvant allowed) were enrolled. TEX regimen was administered as defined: T 35 mg/m2 and E 70 mg/m2 on days (d) 1 and 8, with X 800 mg/m2 bid on d1–14 every 22 days Toxicity assessment was done 3-weekly while CT scans were repeated 9-weekly. Results: 35 of 48 pts were enrolled until 06/08: 28 male / 7 female, median age 59 (36–81) years, ECOG PS 0/1/2 69%/31%/0%, gastric / gastroesophageal cancer 60%/40%, distant metastases 96%, tumor in situ 37%. The most common toxicities reported were (CTC grade [gr] 3/4): diarrhea 20%/3%, vomiting 11%/3%, asthenia and neurotoxicity each 9%/0%. Mucositis and hand-foot-syndrome were observed in (grade 1+2 / grade 3) 29%/0% and 26%/3%, respectively. Hematoxicity was mild with grade 3 anemia in 10% and no other grade 3/4 toxicity except one episode of febrile neutropenia . Of 25 pts evaluable so far, first tumor response assessment revealed (RECIST criteria) partial response in 36% and stable disease in 40% of patients. Conclusions: TEX is a safe and tolerable regimen for patients with metastatic gastric cancer. Preliminary efficacy results indicate promising activity. Mature data including progression free survival will be presented at the meeting. [Table: see text]

1108 Objectives: To evaluate efficacy and safety of SEGEMOX regimen for previously A and T pre-treated MBC patients. Methods: Forty-five women with MBC not eligible for A and/or T chemotherapy were enrolled on SEGEMOX study. SEGEMOX was delivered as follows: Gemcitabine was given at 1000 mg/m2/100min on day 1, followed by oxaliplatin at 100 mg/m2/120min iv on day 2 every 2 weeks. Efficacy results were analyzed and are presented in an intention to treat analysis and toxicity according to the total number of cycles regimen. Results: Forty-four of the 45 patients received at least 1 cycle of SEGEMOX. Fifty-eight perccent of the patients have received previous adjuvant chemo, 36% 1st line and 42% 2nd line for MBC before the protocol inclusion. Visceral metastases were dominant site of disease (44% liver; 36% lung; 44% bone). Median age of the population was 55.8 years (36–73). After a median of 7.7 cycles (3.5 months of treatment); the overall response rate (ORR) is 38% [95%CI; 23%-51%] [1 CR (2.2%) and 16 PR (35.6%)]; 33% of stable disease [95%CI; 17%-43%], 24.4% progressive disease with a clinical benefit (CB) of 71% [95%CI; 57%-85%]. The median progression free survival (PFS) is 7.1 months for responders and 4.8 months for patients with stable disease. The all population median overall survival (OS) is 21.4 months with 22.7 months MOS for responders. Concerning toxicity analysis: 339 cycles of gemcitabine and 312 of oxaliplatinum were delivered. Respectively, grade 3–4 neutropenia occurred in 43% of patients (febrile neutropenia in 7%), grade 3–4 thrombocytopenia in 41%, and anemia in 2.3%. The most frequent non hematologic toxicities were represented by grade 3 peripheral neuropathy (Levi Scale) in 11.4% of the patients and grade 2 alopecia in 11.4%. For the subgroup of hormone receptor negative MBC (n = 12) the ORR is 33% [95%CI; 2%-64%], CB 50% [95%CI; 16%-73%], PFS of 2.8 months and MOS of 12 months. Conclusions: The SEGEMOX combination has relevant activity in A and T not eligible MBC patients, with a manageable toxicity profile. In the limited number of patients with HRN MBC even if the response rate is close to the overall population the prognosis seems still worse. No significant financial relationships to disclose.

4570 Background: Cetuximab significantly enhances efficacy of radiotherapy and chemotherapy in head and neck cancer. We investigated the safety and feasibility of adding cetuximab to neoadjuvant chemoradiation of locally advanced esophageal cancer. Methods: Pts with resectable, locally advanced squamous cell carcinoma (SCC) or adenocarcinoma (AC) of the thoracic esophagus or gastroesophageal junction (staged by EUS, CT and PET scan) were treated with 2 cycles of induction chemotherapy (docetaxel 75mg/m2, cisplatin 75mg/m2 q3w and weekly cetuximab 250mg/m2), followed by concomitant chemo- immuno-radiation therapy (CIRT: docetaxel 20mg/m2, cisplatin 25mg/m2 and cetuximab 250mg/m2 weekly five times concomitant with 45 Gy radiotherapy in 25 fractions); followed by surgery 4–8 weeks later. The phase I part consisted of 2 cohorts of 7 patients each, without and with docetaxel during CIRT, respectively. Interpatient dose-escalation (adding docetaxel during CIRT) was possible if < 2 out of 7 pts of the 1st cohort experienced limiting toxicity. Having finished the phase 1 part, 13 additional patients were treated with docetaxel-containing CIRT in a phase II part. Pathological response was evaluated according to the Mandard classification. Results: 27 pts from 12 institutions were included. As of today, results from 20 pts are available (cohort 1: 7, cohort 2: 7, phase ll : 6). Median age was 64yrs (range 47–71). 11 AC; 9 SCC. 19 pts (95%) completed CIRT (1 pt stopped treatment during induction therapy due to sepsis). 17 pts underwent resection (no surgery: 1pt for PD, 1pt for cardiac reasons). Grade 3 toxicities during CIRT included anorexia 15%, dysphagia/esophagitis 15%, fatigue 10%, nausea 10%, pruritus 5%, dehydration 5%, nail changes 5% and rash 5% .1 pt suffered from pulmonary embolism. 13 pts (65%, intention-to-treat) showed a complete or near complete pathological remission (cohort 1: 5, cohort 2: 4, phase II: 4). Conclusions: Adding cetuximab to preoperative chemoradiation for esophageal cancer is safe and feasible in a community-based multicenter setting. Antineoplastic activity is encouraging with 65% pathological responders. [Table: see text]
