4566 Background: S0931 is assessing recurrence-free survival in RCC pts randomized to receive EVE versus placebo for one year following nephrectomy. To date, there has been a higher than expected dropout rate due to bothersome tox. Previous reports have shown an association between EVE trough levels and both tox and disease response in RCC pts. Therefore, we have assessed EVE trough levels to evaluate the relationship between measured exposure and probability of tox. This analysis has been approved by the DSMC. Methods: Patients received 10 mg daily EVE or placebo for nine 6-week cycles. Pre-dose whole blood samples collected pre-cycle 2 and pre-cycle 3 were analyzed for EVE. Pts with pre-cycle 2 and/or pre-cycle 3 EVE results were used in the analysis. When both trough levels were available, results were averaged. Pts were segregated into quartiles (Q) based on EVE levels and logistic regression was used to model the following adverse event outcomes using EVE trough as a predictor; any grade 3+ tox, grade 2+ triglycerides, grade 2+ hyperglycemia, grade 2+ oral mucositis, grade 2+ rash, and premature stopping of EVE. Hazard and odds ratios were adjusted for age, BMI and performance status. Results: This study reached its accrual goal and closed on 9/15/2016 with 1545 (775 EVE) randomized patients. A total of 386 pts are included in this preliminary analysis. Median EVE trough was 12.8 ng/mL (range 3.1, 75.6) per 10 mg dose. Event rates for tox were: any grade 3+ tox = 46%, grade 2+ triglycerides = 33%, grade 2+ hyperglycemia = 15%, grade 2+ oral mucositis = 34%, grade 2+ rash = 15%, and premature stopping of EVE = 40%. The risk of grade 2+ triglycerides was increased in Q2 and Q3 vs Q1 (OR = 2.95; p = 0.001 and OR = 3.48; p < 0.001). The risk of grade 2+ rash was increased in Q2 and Q4 vs Q1 (OR = 2.95; p = 0.02 and OR = 3.20; p = 0.01). There was also a trend towards an increased risk of any grade 3+ tox in Q3 vs Q1 (OR = 1.72; p = 0.07). Conclusions: This analysis has identified significant associations between EVE exposure and the probability of tox. EVE analysis is ongoing and the final results will be presented. Clinical trial information: NCT01120249.

7524 Introduction: J9511 demonstrated a significant survival benefit for Cis/CPT11 over Cis/VP16 in Japanese patients (pts) with E-SCLC (Noda, et al. NEJM 2002). S0124 is the confirmatory North American phase III trial (accrual completed) using the identical J9511 protocol. We hypothesized that toxicities would differ between North American & Japanese pts due in part to differences in the distribution of genetic polymorphisms involved in chemotherapy metabolism. Methods: Toxicity data were compared among 706 pts enrolled in J9511 & S0124 receiving common treatment using a logistic model adjusted for age, sex, and performance status (PS). Select polymorphisms of the UGT1A1, ABCB1, & OATP genes in genomic DNA were evaluated in 142 pts in S0124 only (67 Cis/CPT11; 75 Cis/VP16). Associations between toxicity & genotype within each arm were assessed using logistic regression. Results: Pt demographics for J9511 & S0124 respectively: Mean age − 61 & 62 years; Male sex − 131 (86%) & 315 (57%); PS 0 − 19 (13%) & 173 (31%); PS>0 − 133 (87%) & 372 (68%). Comparative toxicities (≥ grade 3) are summarized ( table ). PG analysis in S0124 pts: ABCB1 (C3435T) T/T was associated with an increased risk of CPT11 grade 3+ diarrhea (p=0.04) versus C/C and C/T. UGT1A1 (G3156A) A/A was associated with increased risk of CPT11 neutropenia (p=0.009) & leukopenia (p=0.05). UGT1A1*28 TA7, typically associated with increased CPT11 toxicity, was seen in only 4 pts (2 Cis/CPT11; 2 Cis/VP16); thus no correlation was done. No gene tested was associated with VP16 toxicity. Conclusions: Significant differences in treatment-related myelosuppression exist between J9511 and S0124 pt populations. Certain polymorphisms in genes involved in CPT11 metabolism are significantly associated with CPT11 toxicities in S0124. Additional analyses are ongoing. These results support the hypothesis that toxicities may be associated with distribution of genetic polymorphisms. No significant financial relationships to disclose. [Table: see text]

Background: The phase III MPACT trial demonstrated the superiority of gemcitabine (Gem) combined with Nab-paclitaxel (Nab-P) versus gemcitabine alone in previously untreated patients with metastatic pancreatic ductal adenocarcinoma (PDAC). The purpose of this study was to evaluate the effect of Gem/Nab-P in routine clinical practice. Methods: From January 2015 to December 2018, patients with metastatic PDAC receiving firstline treatment with a combination of gemcitabine and Nab-paclitaxel were included in a multicentre retrospective observational study. Exploratory analyses of efficacy, and prognostic and predictive markers, were performed. Results: The cohort comprised 115 patients (median age 65 [range 50-84] years) with good performance status (ECOG PS 0-1). The median overall survival (OS) was 11 months (95% CI; 9-13) and the median progression-free survival (PFS) was 6 months (95% CI 5-7). Partial response and stable disease were achieved in 44 and 30 patients, respectively, yielding an overall disease control rate (DCR) of 64.3%. Grade 3-4 hematological toxicity frequency was 22.61% for neutropenia, 5.22% for anemia, and 3.48% for thrombocytopenia. Grade 3 asthenia was recorded in 2.61% of patients. No grade 4 non-hematological events were reported. Dose reduction was necessary in 51.3% of the patients. Conclusions: Our results confirm the efficacy and safety of a first-line regimen comprising gemcitabine and Nab-paclitaxel in metastatic PDAC in a real-life population.

PurposeThis phase III trial compared the efficacy and safety of gemcitabine (Gem) plus capecitabine (GemCap) versus single-agent Gem in advanced/metastatic pancreatic cancer.Patients and MethodsPatients were randomly assigned to receive GemCap (oral capecitabine 650 mg/m2twice daily on days 1 to 14 plus Gem 1,000 mg/m2by 30-minute infusion on days 1 and 8 every 3 weeks) or Gem (1,000 mg/m2by 30-minute infusion weekly for 7 weeks, followed by a 1-week break, and then weekly for 3 weeks every 4 weeks). Patients were stratified according to center, Karnofsky performance score (KPS), presence of pain, and disease extent.ResultsA total of 319 patients were enrolled between June 2001 and June 2004. Median overall survival (OS) time, the primary end point, was 8.4 and 7.2 months in the GemCap and Gem arms, respectively (P = .234). Post hoc analysis in patients with good KPS (score of 90 to 100) showed a significant prolongation of median OS time in the GemCap arm compared with the Gem arm (10.1 v 7.4 months, respectively; P = .014). The overall frequency of grade 3 or 4 adverse events was similar in each arm. Neutropenia was the most frequent grade 3 or 4 adverse event in both arms.ConclusionGemCap failed to improve OS at a statistically significant level compared with standard Gem treatment. The safety of GemCap and Gem was similar. In the subgroup of patients with good performance status, median OS was improved significantly. GemCap is a practical regimen that may be considered as an alternative to single-agent Gem for the treatment of advanced/metastatic pancreatic cancer patients with a good performance status.

356154 Background: Combinations of immune checkpoint inhibitors (CPI) blocking PD-1 and CTLA-4 or BRAF/MEK inhibitors have both shown significant antitumor efficacy and overall survival (OS) benefit in patients (pts) with BRAFV600-mutant metastatic melanoma (MM), leading to broad regulatory approval. Little prospective data exists to guide the choice of one over the other as initial therapy or the preferred treatment sequence in this population. The DREAMseq Trial was designed to compare the efficacy and toxicity of the sequence of nivolumab/ipilimumab (N/I) followed by dabrafenib/trametinib (D/T) to the converse sequence. Methods: Eligible pts with treatment-naive BRAFV600-mutant MM were stratified by ECOG Performance Status (PS) 0 or 1 and LDH level and randomized 1:1 to receive Step 1 with either N/I (Arm A) or D/T (Arm B) and at disease progression (PD) were enrolled in Step 2 receiving the alternate therapy, D/T (Arm C) or N/I (Arm D), respectively. Pts received N (1mg/kg)/I (3 mg/kg) q3 wks x 4 doses followed by N 240 IV q2 wks for up to 72 wks (Arms A and D) or D 150 mg po BID and T 2 mg po qD until PD (Arms B and C). In 2019, investigators were given the option to use alternate induction dosing of N (3mg/kg)/I (1 mg/kg) q3 wks x 4 doses for Arms A and D. Cycles were every 6 wks and imaging was obtained at baseline and q12 wks on each arm. Primary endpoint was 2-year OS. At the 4th Interim Analysis with 59% of pts being 2 yrs from enrollment, the DSMC and NCI CTEP recommended halting accrual and releasing the data. Results: Beginning 7/2015, 265 out of a proposed 300 pts were enrolled (133 Arm A and 132 Arm B). Median age was 61 (25-85) and 63% were male. Demographics for Arm A and B were balanced with 67% PS 0 and 60% with normal LDH. As of 7/16/21, at a median follow-up of 27.7 mos, 27 pts had switched to Arm C and 46 to Arm D. Overall Grade 3+ toxicity was 60% in Arm A and 52% in Arm B. Grade 5 treatment-related AEs included 2 on Arm A and 1 on Arm C. ORR to date is: Arm A 46% (52/113), Arm B 43% (49/114), Arm C 48% (11/23) and Arm D 30% (8/27). 37/42 assessed pts in Arm A and 19/37 in Arm B remain in response. Median DOR: Arm A- Not reached; Arm B-12.7 mos (95% CI: 8.2, -) (p <0.001). There were 100 deaths (Arm A to C- 38/Arm B to D- 62). 2-yr OS rate for those starting with Arm A was 72% (95% CI: 62-81%) and for Arm B 52% (95% CI: 42-62%) (log-rank p= 0.0095). PFS showed a trend in favor of Arm A (log-rank p=0.054). Both the PFS and OS curves show a biphasic pattern with Arm B being above Arm A until 6 and 10 mos, respectively. For the 115 pts with documented progression on Step 1 (Arm A-44/Arm B-71), 60 (52%) had registered for Step 2. The principal reason for not enrolling on Step 2 was death from PD within 6 mos (Arm A:15/23; Arm B: 25/32). Conclusions: For pts with advanced BRAFV600-mutant MM, the treatment sequence beginning with the CPI combination of N/I resulted in superior OS, which became evident at 10 mos, with longer Step 1 DOR and more ongoing responses than the treatment sequence beginning with D/T. Clinical trial information: NCT02224781.

PURPOSE To determine the activity and evaluate the toxicity of uracil and tegafur in a 4:1 molar concentration (UFT; Taiho Pharmaceutical Ltd, Tokyo, Japan) plus oral calcium leucovorin in the treatment of patients with advanced colorectal carcinoma. PATIENTS AND METHODS Forty-five patients with advanced, bidimensionally measurable metastatic colorectal carcinoma were enrolled onto the trial. None of the patients had received prior chemotherapy or biologic therapy for advanced disease. Patients received either 350 or 300 mg/m2/d UFT plus 150 mg/d leucovorin administered orally in divided daily doses every 8 hours for 28 days followed by a 7-day rest period. Response was evaluated after two courses of therapy. RESULTS Eighteen patients (three treated at 350 mg/m2/d and 15 at 300 mg/m2/d) had partial responses, and one patient had a complete response (response rate, 42.2%; 95% confidence interval, 28% to 58%). Responses were observed in sites that included liver (n = 18), lung (n = 6), and bone (n = 1). Of seven patients who received 350 mg/m2 UFT, prolonged grade 3 diarrhea developed in five; this resulted in a reduction in the UFT starting dose to 300 mg/m2/d in the remaining 38 patients. Grade 1 or 2 toxic effects included diarrhea, nausea, vomiting, abdominal cramping, anorexia, fatigue, oral mucositis, excessive lacrimation, and rash. Among 38 patients who received the 300-mg/m2/d dose, grade 3 toxic reactions included diarrhea (n = 4), vomiting (n = 2), abdominal cramping (n = 1), and fatigue (n = 2). CONCLUSION UFT 300 mg/m2/d plus oral leucovorin 150 mg/d administered for 28 days demonstrated significant activity against metastatic colorectal carcinoma. This oral regimen was well tolerated and devoid of the neutropenia or significant oral mucositis that complicates intravenous schedules of fluorouracil (5-FU) plus leucovorin. The results of this clinical trial will serve as the basis for a randomized phase III study to compare this oral schedule of UFT plus leucovorin with intravenous 5-FU plus leucovorin to determine the relative efficacy, impact on quality of life, and cost of the two regimens.

Purpose We hypothesized that the addition of gefitinib, an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, to docetaxel would enhance therapeutic efficacy in squamous cell carcinoma of the head and neck (SCCHN). Patients and Methods Patients with recurrent or metastatic SCCHN with Eastern Cooperative Oncology Group (ECOG) performance status of 2, or patients with ECOG performance status of 0 to 2 but were previously treated with chemotherapy, were randomly assigned to receive weekly docetaxel plus either placebo (arm A) or gefitinib 250 mg/d, orally (arm B) until disease progression. At the time of progression, patients in the placebo arm could receive single-agent gefitinib. EGFR, c-MET, and KRAS mutations and polymorphisms in drug metabolizing enzymes and transporters were evaluated by pyrosequencing. Results Two hundred seventy patients were enrolled before the study was closed early at interim analysis (arm A, n = 136; arm B, n = 134). Median overall survival was 6.0 months in arm A versus 7.3 months in arm B (hazard ratio, 0.93; 95% CI, 0.72 to 1.21; P = .60). An unplanned subset analysis showed that gefitinib improved survival in patients younger than 65 years (median 7.6 v 5.2 months; P = .04). Also, there was a trend for improved survival in patients with c-MET wild-type (5.7 v 3.6 months; P = .09) regardless of treatment. Grade 3/4 toxicities were comparable between the two arms except that grade 3/4 diarrhea was more common with docetaxel/gefitinib. Of 18 eligible patients who received gefitinib after disease progression in arm A, one patient had a partial response. Conclusion The addition of gefitinib to docetaxel was well tolerated but did not improve outcomes in poor prognosis but otherwise unselected patients with SCCHN.

Purpose To determine the prognostic importance of p16 and human papillomavirus (HPV) in patients with oropharyngeal cancer treated on a phase III concurrent chemoradiotherapy trial. Patients and Methods Patients with stage III or IV head and neck squamous cell cancer were randomly assigned to concurrent radiotherapy and cisplatin with or without tirapazamine. In this substudy, analyses were restricted to patients with oropharyngeal cancer. p16 was detected by immunohistochemistry, and HPV was detected by in situ hybridization and polymerase chain reaction. Results Slides were available for p16 assay in 206 of 465 patients, of which 185 were eligible, and p16 and HPV were evaluable in 172 patients. One hundred six (57%) of 185 were p16-positive, and in patients evaluable for both p16 and HPV, 88 (86%) of 102 p16-positive patients were also HPV-positive. Patients who were p16-positive had lower T and higher N categories and better Eastern Cooperative Oncology Group (ECOG) performance status. p16-positive tumors compared with p16-negative tumors were associated with better 2-year overall survival (91% v 74%; hazard ratio [HR], 0.36; 95% CI, 0.17 to 0.74; P = .004) and failure-free survival (87% v 72%; HR, 0.39; 95% CI, 0.20 to 0.74; P = .003). p16 was a significant prognostic factor on multivariable analysis (HR, 0.45; 95% CI, 0.21 to 0.96; P = .04). p16-positive patients had lower rates of locoregional failure and deaths due to other causes. There was a trend favoring the tirapazamine arm for improved locoregional control in p16-negative patients (HR, 0.33; 95% CI, 0.09 to 1.24; P = .13). Conclusion HPV-associated oropharyngeal cancer is a distinct entity with a favorable prognosis compared with HPV-negative oropharyngeal cancer when treated with cisplatin-based chemoradiotherapy.

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.

7565 Background: Standard first-line chemotherapy for elderly NSCLC pts has been considered as a monotherapy with vinorelbine or gemcitabine globally. However, we have demonstrated the high efficacy of CP for elderly pts in our previous trial (Ann Oncol 2010). Meanwhile, D has been considered as an alternative option for this population in Japan according to the result of WJTOG9904 (JCO 2006). Thus we compared the two regimens to select the proper candidate for future phase III trial. Methods: Eligible pts were aged 70 years or older with newly diagnosed stage IIIB/IV NSCLC; ECOG performance status 0-1; adequate organ function; written informed consent. Pts were randomized to receive carboplatin (AUC 6) on day 1 and paclitaxel (70mg/m2 on day 1, 8, and 15) every 4 weeks or D (60mg/m2 on day 1) every 3 weeks. The primary endpoint was overall response rate (ORR), and secondary endpoints were progression-free survival (PFS), overall survival, and toxicity profile. Assuming that ORR of 40% would be potential usefulness while ORR of 20% would be the lower limit of interest, 40 pts in each arm were required if expect 10% loss to follow up. Results: Between July 2006 and September 2010, 84 pts were enrolled and 41 pts in CP arm and 42 pts in D arm were eligible (median age, 76 years; 75% male; 72% stage IV). Median treatment cycle was 4 in each arm (CP, range 1-6; D, range 1-8). ORRs were 51% (95%CI: 36-66%) and 26% (95%CI: 12-39%) in the CP and D arm, respectively. With a median follow-up of 18.4 months, median PFS were 6.5 and 3.9 months in the CP and D arm, respectively (Logrank, P=0.0027). Grade 3 or severer toxicities were as follows: neutropenia (CP, 56% and D, 79%), anemia (CP, 15% and D, 7%), thrombocytopenia (CP, 10% and D, 0%), infection (CP, 20% and D, 25%). One treatment-related death due to neutropenia, pneumonia, and lethal arrhythmia occurred in D arm but none in CP arm. Conclusions: The platinum doublet CP achieved higher activity with an acceptable toxicity profile for elderly pts with advanced NSCLC compared to monotherapy with D. The superiority of CP to the monotherapy in this trial is consistent with results of recent IFCT-0501 trial (Lancet 2011).

Increased Risk

550 Background: Preoperative radiochemotherapy (RCT) is the standard of care for patients (pts) with locally advanced rectal adenocarcinoma. However elderly pts may have an increased risk of adverse events after combined modality treatment. The randomized trial ACCORD 12/0405 PRODIGE 2 compared 5 weeks of treatment with radiotherapy 45 Gy/25 fractions (f) with concurrent capecitabine 800 mg/m² twice daily 5 days per week (Cap 45) or radiotherapy 50 Gy/25 f with capecitabine 800 mg/m2 twice daily, 5 days per week and oxaliplatin 50 mg/m2 once weekly (Capox 50), results of efficacy (complete pathologic response) were not different between the two arms. We analyzed the results of RCT according to pts age. Methods: All eligible pts (n=584) were included in this exploratory analysis. Pts were divided in 2 groups: <70 y and ≥70 y. Toxicity and tumor regression scores were compared between the 2 groups. Results: 442 pts were <70 y and 142 were ≥70 y. Pts characteristics were well balanced between groups (gender, ECOG performance status, primary tumor, histology). Tolerance was worse in pts ≥70 y as shown in the table. Surgical procedures were not different between the 2 groups. Results on histological response were similar between the 2 groups: complete pathologic response was 16.9% (95% CI 13.1 to 20.2%) for pts <70 y and 14.7% (95% CI 9.2 to 21.8%) for pts ≥70 y, (p=0.55) and rates of R0 surgery for pts < 70 y and pts ≥ 70 y were respectively: 90.6% and 88.2%, (p=0.54). Conclusions: As tolerance of elderly pts treated with preoperative RTCT is worse than in younger pts, appropriate therapeutic schedule are warranted for these pts. [Table: see text]
