TPS8581 Background: The results of current studies are considered acceptable evidence to support the hypothesis of efficacy of the proposed combination of immunotherapy with chemotherapy (CT-IO) in patients with NSCLC stages Ib-IIIA candidates for adjuvant treatment. Methods: This is an open-label, randomised, two-arm, phase III, multi-centre clinical trial. Primary objective and endpoint: The primary objective is disease free survival (DFS) defined time from randomization to the earliest event defined as disease recurrence, any new lung cancer (even in the opposite lung), or death from any cause at any known point in time Sample size: 210 patients NSCLC stages Ib-IIIA (Experimental Arm (Adjuvant Chemotherapy-Inmunotherapy + maintenance adjuvant Inmunotherapy): 105 patients, Control Arm (Adjuvant Chemotherapy): 105 patients Treatment Patients randomised to the experimental arm will receive Nivolumab 360mg + Paclitaxel 200mg/m2 + Carboplatin AUC5 for 4 cycles every 21 days (+/- 3 days) as adjuvant treatment followed by maintenance adjuvant treatment for 6 cycles with Nivolumab 480 mg Q4W (+/- 3 days). Patients randomized to the control arm will receive Paclitaxel 200mg/m2 + Carboplatin AUC5 for 4 cycles every 21 days (+/- 3 days) followed by 2 observation visits. Total trial duration: 6.5 years, 3.5 years of recruitment, 1 year of adjuvant treatment or observation and 2 years of follow up. The start date was January 2021. The estimated primary completion date is June 2027. Clinical trial information: NCT04564157.

4507 Background: Some chemotherapy-naïve patients with locally advanced bladder cancer (LABC) after radical cystectomy (RC) are sufficiently de-conditioned that they are not candidates for adjuvant chemotherapy or decline it, even though such treatment may be warranted. There is no clear alternative adjuvant therapy for these patients, who are usually observed. In this study, we compare post-op radiotherapy (PORT) vs. adjuvant chemotherapy in a randomized clinical trial. We hypothesized that PORT can achieve comparable disease-free survival (DFS). Methods: A randomized phase III trial was opened to compare PORT vs. sequential chemo+PORT after RC for LABC & accrued from 2002–2008 at the NCI in Cairo. In 2007, a third arm comparing adjuvant chemo was added. Herein, we report the results of PORT vs. adjuvant chemo. Patients ≤70 y/o with ≥1 of the following factors (≥pT3b/T4a, grade 3, or positive nodes) with negative margins after RC + pelvic node dissection were eligible. Routine follow-up & pelvic CT q6 months were performed. PORT included 3D conformal pelvic RT (45Gy/1.5Gy BID). Chemo included gemcitabine/cisplatin x 4. Post-hoc non-inferiority exploratory analysis was performed. Results: The PORT arm accrued 78; the chemo arm accrued 45. 51% had urothelial carcinoma; 49% had squamous cell carcinoma/other. The two arms were well-balanced except for gender (p = 0.06). Two-year outcomes & overall adjusted hazard ratios (HR) for PORT vs. chemo alone were 54% vs. 47% (HR 0.65(95%CI 0.35-1.19, p = 0.16) for DFS; 92% vs. 69% (HR 0.28(95%CI 0.10-0.82), p = 0.02 for LRFS; 75% vs. 79% (HR 2.39(95%CI 0.94-6.09), p = 0.07) for DMFS; 61% vs. 60% (HR 0.94(95%CI 0.52-1.69), p = 0.83) for OS. Late grade ≥3 GI toxicity was observed in 6 PORT patients (8%) & 1 chemo patient (2%). Based on our data, there is a greater than 90% probability that the true difference in 2 yr DFS is less than 10%, the pre-specified non-inferiority margin. Conclusions: This randomized study demonstrates superior local control with PORT vs. adjuvant chemo with no significant differences in DFS, DMFS or OS. Results suggest that PORT could be an option for patients with LABC after RC who are medically unfit for adjuvant chemo or who decline it. Clinical trial information: NCT01734798.

PURPOSE In a randomized clinical trial (European Organization for the Research and Treatment of Cancer [EORTC] no. 40813) on adjuvant chemotherapy in gastric cancer, results obtained after administration of the FAM2 regimen (fluorouracil [5-FU], doxorubicin, and mitomycin) were compared with results obtained after surgery alone to assess the effect of this regimen on overall survival, time to progression, and disease-free interval. PATIENTS AND METHODS Three hundred fourteen patients who had undergone curative resection for stage II or stage III (International Union Against Cancer [UICC] 1978) gastric adenocarcinoma were randomized to receive chemotherapy (treatment arm) or no further treatment (control arm). The chemotherapy schedule was repeated every 43 days for seven cycles. The log-rank test and the Cox model were used for statistical analysis. RESULTS Of 314 patients, 159 comprised the control group and 155 the FAM2 group. Nineteen FAM2 patients never received chemotherapy. The median number of cycles was five. Of the patients started on adjuvant treatment, severe hematologic and nonhematologic toxicity (grades 3 or 4, World Health Organization [WHO] scale) occurred, respectively, in 6% to 9% and in 1% to 29% of cases. The overall 5-year survival rate was 70% for stage II and 32% for stage III patients. No statistically significant difference was found between overall survival of the two treatment arms (P = .295). However, time to progression was significantly delayed in the FAM2 arm (P = .020) and disease-free survival showed borderline significance (P = .068). CONCLUSION FAM2, in view of its high toxicity, cannot be advocated as standard adjuvant treatment for gastric cancer. Large-scale clinical trials using more active, less toxic regimens are required to demonstrate whether adjuvant chemotherapy provides any real benefit.

Purpose Gemcitabine is standard of care in the adjuvant treatment of resectable pancreatic ductal adenocarcinoma (PDAC). The epidermal growth factor receptor tyrosine kinase inhibitor erlotinib in combination with gemcitabine has shown efficacy in the treatment of advanced PDAC and was considered to improve survival in patients with primarily resectable PDAC after R0 resection. Patients and Methods In an open-label, multicenter trial, patients were randomly assigned to one of two study arms: gemcitabine 1,000 mg/m2 days 1, 8, 15, every 4 weeks plus erlotinib 100 mg once per day (GemErlo) or gemcitabine (Gem) alone for six cycles. The primary end point of the study was to improve disease-free survival (DFS) from 14 to 18 months by adding erlotinib to gemcitabine. Results In all, 436 patients were randomly assigned at 57 study centers between April 2008 and July 2013. A total of 361 instances (83%) of disease recurrence were observed after a median follow-up of 54 months. Median treatment duration was 22 weeks in both arms. There was no difference in median DFS (GemErlo 11.4 months; Gem 11.4 months) or median overall survival (GemErlo 24.5 months; Gem 26.5 months). There was a trend toward long-term survival in favor of GemErlo (estimated survival after 1, 2, and 5 years for GemErlo was 77%, 53%, and 25% v 79%, 54%, and 20% for Gem, respectively). The occurrence or the grade of rash was not associated with a better survival in the GemErlo arm. Conclusion To the best of our knowledge, CONKO-005 is the first study to investigate the combination of chemotherapy and a targeted therapy in the adjuvant treatment of PDAC. GemErlo for 24 weeks did not improve DFS or overall survival over Gem.

TPS3618 Background: Both anti-EGFR and anti-VEGF therapies have shown clinical benefit when they are added in first and second-line in L-sided CRC. The conflicting results in anti-VEGF vs. anti-EGFR studies (FIRE-3, PEAK and CALGB/SWOG 80405 studies) suggest that the sequence of targeted therapies added to FOLFOX or FOLFIRI regimens in first- and second-line treatment could be an important factor in the overall survival (OS) of mCRC patients. Currently, there are no randomized data on the sequential use of an anti-EGFR followed by an anti-VEGF or vice versa. Therefore, the aim of this randomized clinical trial is to compare the efficacy of two treatment sequences, panitumumab followed by bevacizumab versus bevacizumab followed by panitumumab in combination with FOLFOX chemotherapy in first-line and with FOLFIRI in second-line in patients with wild-type RAS, primary L-sided, metastatic colorectal cancer (mCRC). Methods: A phase III, multicentre, open-label and randomized two-arm clinical trial. Untreated patients with wild-type RAS mCRC (determined locally), primary L-sided and unresectable will be screened for this trial. Eligible patients will be randomized 1:1 to receive first-line (1L) panitumumab plus FOLFOX and then bevacizumab plus FOLFIRI as second-line (2L) treatment (Seq. 1) or bevacizumab plus FOLFOX as 1L and then panitumumab plus FOLFIRI as 2L treatment (Seq. 2). Randomization will be stratified by number of metastatic organs involved (1 vs > 1). Primary objective is the comparison of the progression free survival (PFS) rate at 35 months (m) of Seq 1 vs Seq. 2. Secondary objectives: PFS from randomization to 2nd progression or death, OS rate at 35 months and OS of Seq. 1 vs Seq. 2; PFS, objective response rate, disease control rate, early tumour shrinkage, Depth of Response, duration and time to response and safety in 1L treatment and in 2L treatment in each Sequence arm. Exploratory objectives: impact of baseline biomarkers predictive of the efficacy in each Sequence arm and the clinical impact of clonal dynamics by longitudinal analysis of circulating tumour deoxyribonucleic acid (ctDNA) in plasma. The trial is in progress; 28 of up to 370 planned patients have been recruited at the end of January 2019 (first patient in 31 October 2018). Clinical trial information: NCT03635021.

4000 Background: In metastatic pancreatic cancer (PC), nab-P/G demonstrated significantly longer overall survival (OS) vs G. APACT assessed efficacy & safety of nab-P/G vs G in surgically resected PC. Methods: Treatment (tx)-naive patients (pts) with histologically confirmed PC, macroscopic complete resection, ECOG PS 0/1, & CA19-9 < 100 U/mL were eligible. Stratification factors: resection status (R0/R1), lymph node status (LN+/−), & geographic region. Tx was initiated ≤ 12 wks postsurgery. Pts received nab-P 125 mg/m2 + G 1000 mg/m2 or G 1000 mg/m2 on days 1, 8, 15 of six 28-day cycles. Primary endpoint was disease-free survival (DFS) by independent reviewer (IR); IRs received baseline clinical data & scans. Secondary endpoints were OS & safety. ≈438 DFS events were needed for 90% power to detect an HR for disease recurrence or death of 0.73 with nab-P/G vs G at a 2-sided significance level of 0.05. Results: 866 pts were randomized. Median age was 64 y (range, 34 - 86); most pts had ECOG PS 0 (60%), LN+ (72%), & R0 (76%). 69% of pts completed 6 tx cycles ( nab-P/G, 66%; G, 71%). Median follow up for OS was 38.5 mo. Median IR-assessed DFS (439 events) was 19.4 mo ( nab-P/G) vs 18.8 mo (G) (HR, 0.88; 95% CI, 0.729 - 1.063; stratified log-rank P = 0.1824). Investigator-assessed DFS (571 events) was 16.6 mo ( nab-P/G) vs 13.7 mo (G) (HR, 0.82; 95% CI, 0.694 - 0.965; nominal P = 0.0168). Interim OS (427 events) was 40.5 mo ( nab-P/G) vs 36.2 mo (G) (HR, 0.82; 95% CI, 0.680 - 0.996; nominal P = 0.045). Grade ≥ 3 TEAEs were reported in 86% vs 68% of pts with nab-P/G vs G. The most common grade ≥ 3 hematologic & nonhematologic TEAEs with nab-P/G vs G were neutropenia (49% vs 43%) & fatigue (10% vs 3%). TEAEs led to death in 2 pts in each arm. Conclusions: IR DFS with nab-P/G was not significantly longer vs G; median DFS with G was longer than historical data. DFS by investigator (sensitivity analysis) and interim OS were improved with nab-P/G vs G (HR 0.82 for both). Adjuvant nab-P/G may be an option for pts who are ineligible for FOLFIRINOX. Additional OS follow-up may better support nab-P/G as an option in the adjuvant setting. Clinical trial information: NCT01964430.

103 Background: The clinical benefit and safety profile of apatinib in advanced gastric cancer have been established in the randomised controlled phase III clinical trial (J Clin Oncol. 34(13):1448-54). A post-marketing study to confirm the safety and efficacy of apatinib is ongoing in a broad range of patients (pts). Methods: This is a single-arm, open-label, multi-center, Phase IV trial with the target sample size of 2000+ (ClinicalTrials.gov Identifier: NCT02426034). Pts were recruited to receive oral apatinib until disease progression, death or unacceptable toxicity. The primary objective was safety, and the secondary objectives included overall response rate (ORR), disease control rate (DCR), progression free survival (PFS) and overall survival (OS). Results: Herein, we report the preliminary data as documented in the EDC System. As of Jul 10, 2017, 1037 pts were enrolled from 138 hospitals across China. Pts characteristics were: median age 59 yrs, male/female 72.0/28.0%, ECOG PS 0/1/≥2 16.6/66.2/17.2%, stage IV 91.0%. 336 (32.4%) pts interrupted treatment and dose modification occurred in 172 (16.6%) pts (reduction 132/12.7%; rise 87/8.4%). Eventually, the mean dosage was 526.2 mg/d. 652 (62.9%) pts had 4407 drug-related adverse events (DRAEs). Grade ≥3 DRAEs occurred in 300 (28.9%) pts. Severe AEs were reported by 221 (21.3%) pts. The most common DRAEs were proteinuria (19.3%), hypertension (18.8%), leukocyte decrease (16.4%), fatigue (14.2%), platelet decrease (13.6%), hand-foot-skin reaction (11.1%) and neutrophil decrease (10.1%). 820 pts were evaluable for efficacy analysis. The best ORR and DCR were 10.7% and 70.0%, respectively. The median PFS and OS were 4.60 (95%CI, 3.25–4.73) and 6.57 (95%CI, 5.78–7.59) months, respectively. Conclusions: Apatinib monotherapy is effective and has a favorable toxicity profile in real-world clinical setting. The preliminary results of this Phase IV study confirmed the safety and efficacy of apatinib demonstrated in the Phase II and III trials. Updated results will be discussed. Clinical trial information: NCT02426034.

Abstract Background Surgery is the only treatment option for operable gastric cancer. The CLASSIC and ACTS-GC studies showed that the 5-year overall survival (OS) of patients with stage III gastric cancer undergoing D2 gastrectomy is still very low. Whether adjuvant nanoparticle albumin-bound paclitaxel (nab-paclitaxel) combined chemotherapy is more effective than the XELOX standard adjuvant chemotherapy in patients with stage III gastric cancer has not been confirmed. Methods This is a multicenter, open-label, phase III clinical study. In this trial, 616 patients with locally advanced stage III gastric cancer that underwent curative D2 radical surgery and achieved R0 are planned to be included. Patients will be randomized 1:1 to nab-paclitaxel combined with S-1 (AS) vs. oxaliplatin combined with capecitabine (XELOX). XELOX group: Patients assigned to the XELOX group received eight 3-week cycles of oral capecitabine (1000 mg/m2) twice daily on days 1–14 of each cycle plus intravenous oxaliplatin 130 mg/m2 on day 1 of each cycle. AS group: AS group received eight 3-week cycles of oral S-1 (80–120 mg) (< 1.25 m2, 40 mg; 1.25 to < 1.5 m2, 50 mg; and > 1.5 m2, 60 mg) twice daily on days 1–14 plus intravenous nab-paclitaxel 120 mg/m2 on days 1 and 8 of each cycle. The primary endpoint was the 3-year disease-free survival (3-year-DFS) defined as the time from randomisation to the time of recurrence of the original gastric cancer, development of a new gastric cancer, or death from any cause. The secondary endpoints were the overall survival, (defined as the time from the date of randomisation to date of death from any cause) and safety (any adverse event). Discussion Compared with previous studies, this study includes nab-paclitaxel based on S-1 adjuvant chemotherapy, which is expected to achieve better efficacy and lower toxicity than the standard treatment. This study is the first clinical study to evaluate the safety and efficacy of nab-paclitaxel combined with S-1 in patients with stage III gastric cancer after D2 radical resection. Trial registration This clinical trial has been registered with ClinicalTrials.gov, registration number: NCT04135781, on October 20th, 2019.

517 Background: The standard duration of adjuvant chemotherapy (CT) in patient with stage III colorectal cancer is 6 months. On the other hand, no clinical trial which investigate an optimal duration of oral chemotherapeutic agents has yet been implemented for adjuvant treatments. According to the ACCENT database (Sargent, et al. J Clin Oncol 27: 872- 877, 2009), 83% of recurrences in stage II and III pts have occurred within the first 3 years after surgery and peak was observed around one year after surgery. Also, single-agent FU-based adjuvant CT reduced the hazard rate of OS, DFS, and TTR, although the peak of events around one year was still remained especially for stage III pts. We analyzed the data of recurrent risk of curatively resected colon cancer pts provided by JFMC7-1-7-2-15, X-ACT. Surgery alone group and 6 months CT (5FU/LV or capecitabine [Cape]) showed highest peak between 12 months to 18 months after surgery, but 12 months oral 5-FUs group did not show recurrence peak between 12 months to 18 months after surgery. Therefore, to clarify the benefit of 12 month administration of Cape, we planned a phase III randomized trial for a comparison of 6 months treatment and 12 months treatment. Methods: JFMC37 is a multicenter, randomized phase III trial. Patients with fully resected stage III colon or recto sigmoid cancer were eligible. Patients were randomized 1:1 to receive Cape of 6 months (arm A) or Cape of 12 months (arm B). Primary endpoint is disease-free survival. The statistical design is based on superiority hypothesis; 5-yrs DFS is 60% in arm A, 67% in arm B; unilateral α=0.05, 1-β=0.8; and planed accrual is 1200 pts. Results: Between September 2008 to December 2009, 1,304 pts were randomized. Patients characteristics are (armA/armB); number 653/651, gender M352-F301/M343-F308, median age 65 years/65 years, ECOG PS=0-1 620-33/632-19, involvement of lymph nodes=N0-N1-N2 503-130-20/499-128-24. There were no differences in baseline characteristics between arm A and arm B. Conclusions: This trial is expected to show if 1 year adjutant chemotherapy with capecitabine can reduce the peak of recurrence in 1 year and provide long-term OS benefit. [Table: see text]
