18123 Background: Concurrent chemoradiotherapy is standard of care for unresectable patients and the most widely cited trials include the locally advanced multi-modality protocol (LAMP) study, SWOG S9019 and S9504. Our institutional approach represents a merger between the protocols utilized in two of these phase II studies: chemoradiotherapy from the LAMP study and consolidation therapy from SWOG S9504. Methods: We identified all stage III patients treated at the NF/SG VHS from Jan 2001 to Dec 2005. Eligible patients who had unresectable stage III NSCLC were included in the analysis. We treated 34 patients with weekly paclitaxel 45 mg/m2 plus carboplatin AUC 2 and concurrent TRT 63.0 Gy over 7 weeks. Four weeks after the completion of chemoradiotherapy, docetaxel 75 mg/m2 was given every 3 weeks for 21 days for 3 cycles as consolidation. Our primary endpoints were overall and progression free survival. The secondary endpoints were response rate and toxicity. Results: With a median age of 65 years and follow-up time of 25.9 months, median overall survival was 13.7 mos. Median progression free survival was 9.8 mos. The overall response rate was 68% including 5 CRs (15%). The most common grade 3/4 toxicities included pneumonitis (21%), esophagitis (21%), neutropenia (21%) [febrile neutropenia (9%)], neuropathy (18%), anemia (15%) and hypersensitivity to paclitaxel (9%). 62% of patients were able to complete the planned treatment. There were no treatment related deaths. At the time of this analysis, 9 patients were alive (26%) including 7 without progression (21%). Conclusions: Chemoradiotherapy with weekly carboplatin and paclitaxel followed by consolidation therapy with docetaxel is associated with comparable outcomes to other combined modality regimens. Given the advanced age and co-morbidities of our population, this regimen was generally well tolerated with the expected toxicities and can be considered as an option in the treatment of patients with unresectable stage III NSCLC.

8511 Background: In the placebo-controlled Phase III PACIFIC trial of patients with unresectable Stage III NSCLC whose disease had not progressed after platinum-based concurrent chemoradiotherapy (cCRT), durvalumab improved overall survival (OS) (stratified hazard ratio [HR] 0.68; 95% confidence interval [CI] 0.53–0.87; p=0.0025; data cutoff [DCO] Mar 22, 2018) and progression-free survival (PFS) (stratified HR 0.52, 95% CI 0.42–0.65; p<0.0001; DCO Feb 13, 2017) based on the DCOs used for the primary analyses, and the degree of benefit remained consistent in subsequent updates. Durvalumab was associated with a manageable safety profile, and did not detrimentally affect patient-reported outcomes, compared with placebo. These findings established consolidation durvalumab after CRT (the ‘PACIFIC regimen’) as the standard of care in this setting. We report updated, exploratory analyses of OS and PFS, assessed approximately 5 years after the last patient was randomized. Methods: Patients with WHO PS 0/1 (and any tumor PD-L1 status) whose disease did not progress after cCRT (≥2 overlapping cycles) were randomized (2:1) 1–42 days following cCRT (total prescription radiotherapy dose typically 60–66 Gy in 30–33 fractions) to receive 12 months’ durvalumab (10 mg/kg IV every 2 weeks) or placebo, stratified by age (<65 vs ≥65 years), sex, and smoking history (current/former smoker vs never smoked). The primary endpoints were OS and PFS (blinded independent central review; RECIST v1.1) in the intent-to-treat (ITT) population. HRs and 95% CIs were estimated using stratified log-rank tests in the ITT population. Medians and OS/PFS rates at 60 months were estimated with the Kaplan–Meier method. Results: Overall, 709/713 randomized patients received treatment in either the durvalumab (n/N=473/476) or placebo (n/N=236/237) arms. The last patient had completed study treatment in May 2017. As of Jan 11, 2021 (median follow-up duration of 34.2 months in all patients; range, 0.2–74.7 months), updated OS (stratified HR 0.72, 95% CI 0.59–0.89; median 47.5 vs 29.1 months) and PFS (stratified HR 0.55, 95% CI 0.45–0.68; median 16.9 vs 5.6 months) remained consistent with the results from the primary analyses. The 60-month OS rates were 42.9% and 33.4% with durvalumab and placebo, respectively, and 60-month PFS rates were 33.1% and 19.0%, respectively. Updated treatment effect estimates for patient subgroups will be presented. Conclusions: These updated survival analyses, based on 5-year data from PACIFIC, demonstrate robust and sustained OS plus durable PFS benefit with the PACIFIC regimen. An estimated 42.9% of patients randomized to durvalumab remain alive at 5 years and approximately a third remain both alive and free of disease progression. Clinical trial information: NCT02125461.

18070 Background: Although combined chemoradiotherapy is the standard of care in stage III NSCLC, the optimal chemotherapy regimen is not established. S-1, a fourth-generation oral fluoropyrimidine is an active new agent for NSCLC and the combination with cisplatin has a favorable toxicity profile. The objective of this study was to evaluate feasibility and efficacy of S plus P with concurrent radiation for unresectable stage III NSCLC. Methods: Patients with histologically or cytologically confirmed NSCLC, 20 to 75 years in age, performance status 0–1, with no prior chemotherapy were eligible for the study. Patients were treated with P (60 mg/m2 on day 1) and S (orally at 40 mg/m2/dose bid (80 mg/m2/d), on days 1 to 14) repeated every 3–4 weeks for 4 cycles and TRT (60 Gy/30 fr over 6 weeks starting on day 2). The primary endpoint was the response rate (RR), and planned sample size for this phase II study was 28 patients (Simon’s two-stage minimax design, P0=70%, P1=90%, a =0.1, β = 0.1). Results: Of 28 patients enrolled between August 2005 and October 2006, 28 were evaluable. There were 24 males and 4 females, median age of 63 (range 40–74) and 11 IIIA and 17 IIIB. Chemoradiotherapy was well tolerated; 2 cycles of SP and 60 Gy of TRT were administered in all patients and 24 (86%) patients received 4 cycles of SP. During concurrent chemoradiotherapy, grade 3 toxicities were neutropenia (8 pts), leukopenia (6 pts), fatigue (6 pts), anorexia (5 pts), febrile neutropenia (4 pts) and, esophagitis (4 pts). Only one grade 4 leukopenia were observed. During consolidation therapy, grade 3–4 neutropenia, anemia, esophagitis, and pneumonitis were developed in 4, 1, 1 and 2 patients, respectively. No toxic deaths have occurred. Overall RR was 85.7% (95% CI: 79.1- 98.7%) with 4 SDs and 24 PRs. The median progression-free survival and median survival is not mature enough to estimate as only 4 progression and no deaths have occurred. Conclusions: This chemoradiotherapy regimen produced promising response rate in patients with stage III NSCLC and it seems to be well-tolerated. No significant financial relationships to disclose.

Background: Adverse events (e.g., pyrexia) may affect treatment patterns and adherence. This study explored pyrexia risk tolerance among melanoma patients when treatment benefit is unknown versus known. Materials & methods: US respondents with stage III (n = 100) or stage III unresectable/stage IV melanoma (n = 125) chose between hypothetical melanoma treatments, defined by reoccurrence/progression-free survival and pyrexia risk, one resembling standard-of-care and one resembling dabrafenib + trametinib. Respondents chose first when efficacy was unknown and then when efficacy was known; pyrexia risk was varied systematically to define maximum acceptable risk. Results: Maximum acceptable risk of pyrexia was statistically significantly higher when efficacy was known versus unknown in stage III patients (85 vs 34%) and stage III unresectable/stage IV patients (66 vs 57%). Conclusion: Patients accepted higher levels of pyrexia risk when they understood treatment benefit.

7528 Background: We conducted a prospective randomized phase III trial comparing induction chemotherapy followed by concurrent chemoradiotherapy (CCRT) versus immediate CCRT to evaluate whether the addition of induction chemotherapy would result in improved survival. Methods: Patients with unresectable stage III NSCLC, ECOG PS 0–1, and weight loss up to 10% were eligible. They were randomized to receive either induction chemotherapy followed by CCRT (arm A) or immediate CCRT (arm B) after stratification for stage (T4N0–2, T1–3N3, T4N3, and stage IIIA), histology (squamous vs non-squamous), and SCLN positivity. Induction chemotherapy consisted of two cycles of gemcitabine (1,000 mg/m2 D1, D8) and cisplatin (70 mg/m2 D1) q 21days. Chemotherapy during CCRT consisted of 6 cycles of weekly paclitaxel (50 mg/m2) and cisplatin (20 mg/m2). Radiation therapy performed with hypofractionated scheme (2.2 Gy/fraction, once a day) and total dose was 66 Gy. Irradiated volume encompassed gross tumor plus 1.0 cm margin. Results: Between March 2003 and June 2006, 134 patients were enrolled. 92% of patients were male and 60% were age 60 or older. Objective tumor response was obtained in 38% after induction chemotherapy. Response rates after completion of CCRT were 72% (95% CI, 61%–83%) on arm A and 79% (95% CI, 69%–89%) on arm B. Grade 3/4 toxicities during induction chemotherapy consisted mainly of neutropenia (11%/3%). During CCRT, grade 3/4 neutropenia was noted in 8%/5% (arm A) versus in 8%/0% (arm B), grade 3 anemia was 8% vs 0%, grade 3 thrombocytopenia 5% vs 0%, and grade 3 esophagitis 16% vs 16%. At median follow-up of 28 months, median survival was 12.6 months (95% CI, 8.6–16.7 months) on arm A versus 18.2 months (95% CI, 11.7–24.8 months) on arm B (P=0.18). Two year survival estimates was 25% (15%–35%) and 43% (31%–55%), respectively. Median progression free survival was 7.5 months (95% CI, 5.6–9.4 months) on arm A and 11.6 months (95% CI, 9.6–13.6 months) on arm B (P=0.04). Conclusions: The addition of induction chemotherapy to CCRT failed to increase the survival of unresectable stage III NSCLC over immediate CCRT. Moreover, the progression free survival was inferior to immediate CCRT. No significant financial relationships to disclose.

TPS8572 Background: In China, the standard of care for patients with unresectable Stage III NSCLC is platinum-based doublet chemotherapy given concurrently or sequentially with radiotherapy. However, the median progression-free survival (PFS) of those patients is poor (approximately 8-10 months) and 5-year overall survival (OS) rate is only 15%. Recently, treatment with durvalumab resulted in significantly longer PFS and OS than placebo for patients with locally advanced/unresectable NSCLC whose disease did not progress after definitive concurrent chemoradiotherapy (cCRT) in PACIFC trial. CS1001 is the first full-length, fully human programmed death ligand-1 (PD-L1) targeted immunoglobin G4 (IgG4, s228p) monoclonal antibody (mAb) developed by the OMT transgenic rat platform. The Phase Ia/Ib study (GEMSTONE-101, NCT03312842) demonstrated that CS1001 was well tolerated and had promising anti-tumor activities across a range of tumors including NSCLC. GEMSTONE-301 is a randomized, double-blind, Phase III study to compare the efficacy and safety of CS1001 versus placebo as consolidation therapy in Stage III unresectable NSCLC patients. This is the first Phase III trial on an anti-PD-(L)1 mAb initiated in China for this indication. Methods: In this trial, eligible patients with locally advanced/unresectable (Stage III) NSCLC who have not progressed after prior concurrent/sequential CRT are 2:1 randomized to receive CS1001 1200 mg, every 3 weeks or placebo, every 3 weeks. Stratification factors for randomization include ECOG status (0 versus 1), chemoradiotherapy (concurrent versus sequential) and total radiotherapy dose ( < 60 Gy versus ≥ 60 Gy). Study treatment will be given for up to 24 months or until disease progression, intolerable toxicity, consent withdrawal, or discontinuation for other reason. Tumor assessments will be performed every 9 weeks in the first year and every 12 weeks thereafter by RECIST v1.1. AEs will be monitored throughout the study and graded according to NCI-CTCAE v4.03. Primary endpoint is PFS evaluated by investigators according to RECIST v1.1. Secondary endpoints are PFS evaluated by Blinded Independent Center Review (BICR), objective response rate, OS, time to death/distant metastasis (TTDM), safety and pharmacokinetics (PK) profile. Enrollment is ongoing across sites in China and will continue until 402 patients are randomized. Clinical trial information: NCT03728556.

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.

e20557 Background: The present study evaluates outcome after chemoradiotherapy (CRT) with concurrent and/or sequential Programmed Cell Death 1 (PD-1) or Ligand 1 (PD-L1) immune checkpoint inhibition (CPI) for inoperable stage III NSCLC patients depending on planning target volume (PTV). Methods: Prospective data of thirty-nine consecutive patients with inoperable stage III NSCLC who completed CRT with sequential durvalumab (72%, 28 patients) or concurrent and sequential nivolumab (28%, 11 patients) were analyzed. Different cut offs for PTV as well as PTV as a continuous variable were evaluated for association with progression-free survival (PFS) and extracranial metastasis-free survival (eMFS). Results: All patients were treated with conventionally fractionated TRT to a total dose of at least 60 Gy (range: 60-63.6Gy), 97% (27 patients) received two cycles of concurrent platinum-based chemotherapy. Median follow-up for the entire cohort was 23.2 (range: 6.0-42.6) months; median overall survival (OS) and eMFS were not reached. Median Progression-free survival (PFS) was 22.8 (95% CI: 10.3-35.2) months. Age (65 years), gender and UICC stage had no significant impact on PFS. There was no significant difference between durvalumab and nivolumab patients. Patients with PTV ≥ 900ccm had a significantly shorter PFS (11.77 vs 26.3 months, p = 0.049) and eMFS (11.7 months vs not reached, p = 0.019). Furthermore, patients with PTV ≥ 900ccm and stage IIIC disease (TNM 8th Ed.) achieved a dismal median PFS of only 3.6 months (vs. 26.3 months p < 0.001). PTV as a continuous variable showed a trend for association with PFS (p = 0.064) and was a significant negative prognosticator for eMFS (p = 0.030; HR: 4.065; 95%CI: 1.148-14.397). Conclusions: PTV has a significant impact on the PFS and eMFS after CRT combined with concurrent and/or sequential CPI in inoperable stage III NSCLC. Patients with PTV ≥ 900ccm had a significantly shorter PFS and eMFS.

Purpose: To improve resectability in patients with stage III–IVA thymic epithelial neoplasms, neoadjuvant chemotherapy and radiotherapy are considered. This retrospective study aimed to investigate the efficacy and safety of neoadjuvant therapies using modern techniques in thymic epithelial neoplasms. Methods: We included 32 patients with Masaoka stage III–IV disease treated at our institution from January 2010 to December 2017. Data regarding clinicopathologic characteristics, treatment protocols, toxicities, and survival were collected. Response was evaluated according to the Response Evaluation Criteria in Solid Tumours 1.1. Survival was assessed using the Kaplan-Meier method. Adverse events were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0. Results: Neoadjuvant radiotherapy alone, chemotherapy alone, sequence chemoradiotherapy, and concurrent chemoradiotherapy were administered to 10 (31.3%), 9 (28.1%), 3 (9.4%), and 10 (31.3%) patients, respectively. Twenty-nine patients (90.6%) underwent R0 resection. The median follow-up time was 38.0 months (3.3–109.5 months). After neoadjuvant therapy, 18 patients (56.3%) achieved partial response and 14 (43.8%) had stable disease. Pathologic complete response was achieved in 6 patients (18.8%), all of whom had thymic carcinoma. The 5-year overall and progression-free survival rates were 90.9% and 67.5%, respectively. For patients with thymic carcinoma, the 5-year overall and progression-free survival rates were 80.0% and 66.2%, respectively. Grade 3 toxicities were observed in only 1 patient (leukopenia). Conclusions: For patients with primary unresectable thymic neoplasms, neoadjuvant chemoradiotherapy is an efficient and safe choice, with favorable response and survival and moderate toxicities. Patients with thymic carcinoma might benefit more from neoadjuvant therapies.
