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.

Recurrence Patterns

704 Background: APACT did not meet the primary endpoint of independently assessed disease-free survival (DFS) with nab-P + G vs G; overall survival showed a nominal improvement. Here, we report recurrence patterns by resection status. Methods: A total of 866 treatment-naive patients (pts) with histologically confirmed pancreatic cancer, R0/R1 resection, CA19-9 < 100 U/mL, and ECOG PS ≤ 1 received 6 cycles of nab-P + G or G on days 1, 8, and 15 Q28 days. Stratification: resection (R0/R1); lymph node status (LN+/−); geographic region. Disease recurrence was per investigator review of CT/MRI scans. Results: Of 571 (66%) pts with investigator-assessed DFS events (median follow up, 35.4 mo), 543 had radiographic progression with 764 recurrent lesions (≥ 20 events: liver, 271; unspecified abdominal organ, 152; lung, 130; surgical bed, 70; mesenteric nodes, 54). Most pts (73%) had only abdominal, 61% had only distant, and 10% had only local recurrence (Table). Although more pts with R1 vs R0 status had recurrence (72% vs 60%), patterns were generally similar, and local recurrence was similarly low. Conclusions: Most recurrences in APACT were distant and in abdomen (liver). Recurrence patterns were generally similar in pts with R0 and R1 status, with low rates of local recurrence. These data may help make more informed pt management decisions. Additional data on patterns by baseline characteristics will be presented. Clinical trial information: NCT01964430 . [Table: see text]

TPS473 Background: Gem therapy improves outcomes in pts with resected PC. However, disease recurrence is common, prompting a need for improved regimens. nab-P + Gem was superior to Gem alone in MPACT, a phase III trial of pts with metastatic PC (mPC) for all endpoints, including overall survival (OS; median, 8.7 vs 6.6 months; hazard ratio [HR] 0.72; P < 0.001). Toxicities were manageable and consistent with prior studies. The APACT trial will compare adjuvant nab-P + Gem vs Gem alone in pts with resected PC. Methods: Pts (≈ 800) with confirmed PC (R0 or R1 resection); stage T1 - 3, N0 - 1, M0; Eastern Cooperative Oncology Group performance status ≤ 1; adequate organ function; and CA19-9 < 100 U/mL within 14 days of randomization are eligible. Pts with mixed-origin tumors; present or previous mPC; any other malignancy within 5 years of randomization; HIV or hepatitis B or C infection; or prior neoadjuvant treatment or radiotherapy for PC are ineligible. Randomization should occur once pts adequately recover from surgery but ≤ 12 weeks after surgery. Pts will receive 6 cycles of either nab-P 125 mg/m2 plus Gem 1000 mg/m2 or Gem 1000 mg/m2 on days 1, 8, and 15 of a 28-day cycle. Stratification factors are resection (R0 vs R1) and nodal (LN+ vs LN−) status and geographic region (North America vs Europe vs Australia vs Asia Pacific). Pts with > 2 dose reductions will be discontinued. The primary endpoint is independently assessed disease-free survival (DFS). Secondary endpoints are OS and safety. Quality of life and correlation of tumor heterogeneity with clinical outcome are exploratory outcomes. At least 489 DFS events from 800 pts will allow 90% power to detect an HR for DFS of 0.74 at a 2-sided significance level of 0.05. Interim analyses, 1 for safety (after 100 pts are treated for ≥ 2 cycles) and 2 for efficacy (the first for futility and the second for futility and superiority), will be performed. As of July 2015, > 400 pts were enrolled, and 80% of all activated study sites (n = 141) randomized ≥ 1 pt. Of the 674 screened pts, ≈ 25% were ineligible, mainly due to postsurgical disease recurrence identified at screening. Pt enrollment is ongoing. ClinicalTrials.gov: NCT01964430. Clinical trial information: NCT01964430.

LBA4002 Background: Surgical resection is a recommended treatment for operable gastric cancer (GC) in general, despite high recurrence rates (40%–80%). Adjuvant chemotherapy aims to reduce recurrences; however, there is currently no universally accepted adjuvant regimen for GC. Methods: CLASSIC is a randomized, open-label, multicenter, international (South Korea, China, and Taiwan) study of XELOX (capecitabine 1000mg/m2 bid, d1–14, q3w and oxaliplatin 130mg/m2, d1, q3w x 8 cycles) vs observation, following D2 gastrectomy. Eligible patients were chemotherapy- and radiotherapy-naive, with stage II (T2N1, T1N2, T3N0), IIIa (T3N1, T2N2, T4N0), or IIIb (T3N2) GC resected within 6 weeks prior to randomization. The primary endpoint is 3-year disease-free survival (DFS). A sample size of 512 patients per arm was planned to observe the 385 DFS events required to provide 80% power at a 5% significance level for the hypothesized treatment effect (hazard ratio [HR] 0.75). The Independent Data Monitoring Committee recommended full evaluation and reporting of results following a positive pre-planned interim analysis at 266 events. Results: The XELOX and observation arms (ITT populations of 520 and 515 patients, respectively) were well balanced for baseline characteristics. The median duration of follow-up was 34.4 (16–51) months. XELOX-related grade 3/4 adverse events (AEs) occurred in 244/496 patients (49%) of the safety population. Neutropenia was the only AE observed in >10% of patients (21%, n=106/496). Serious XELOX-related grade 3/4 AEs occurred in 34/496 patients (7%). There were 62/496 (13%) and 80/476 (17%) deaths on study in the safety populations of XELOX and observation arms, respectively, mostly due to disease progression. Efficacy results in the ITT population are summarized below. Conclusions: This study demonstrates the superior efficacy of adjuvant XELOX vs observation alone following D2 gastrectomy. Although OS data are still immature, there is a trend towards superiority of XELOX. These data support the use of adjuvant XELOX for GC. [Table: see text]

IntroductionHyperthermic intraperitoneal chemotherapy (HIPEC) improved investigator-assessed recurrence-free survival and overall survival in patients with stage III ovarian cancer in the phase III OVHIPEC-1 trial. We analyzed whether an open-label design affected the results of the trial by central blinded assessment of recurrence-free survival, and tested whether HIPEC specifically targets the peritoneal surface by analyzing the site of disease recurrence.MethodsOVHIPEC-1 was an open-label, multicenter, phase III trial that randomized 245 patients after three cycles of neoadjuvant chemotherapy to interval cytoreduction with or without HIPEC using cisplatin (100 mg/m2). Patients received three additional cycles of chemotherapy after surgery. Computed tomography (CT) scans and serum cancer antigen 125 (CA125) measurements were performed during chemotherapy, and during follow-up. Two expert radiologists reviewed all available CT scans. They were blinded for treatment allocation and clinical outcome. Central revision included Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 measurements and peritoneal cancer index scorings at baseline, during treatment, and during follow-up. Time to centrally-revised recurrence was compared between study arms using Cox proportional hazard models. Subdistribution models compared time to peritoneal recurrence between arms, accounting for competing risks.ResultsCT scans for central revision were available for 231 patients (94%) during neoadjuvant treatment and 212 patients (87%) during follow-up. Centrally-assessed median recurrence-free survival was 9.9 months in the surgery group and 13.2 months in the surgery+HIPEC group (HR for disease recurrence or death 0.72, 95% CI 0.55 to 0.94; p=0.015). The improved recurrence-free survival and overall survival associated with HIPEC were irrespective of response to neoadjuvant chemotherapy and baseline peritoneal cancer index. Cumulative incidence of peritoneal recurrence was lower after surgery+HIPEC, but there was no difference in extraperitoneal recurrences.ConclusionCentrally-assessed recurrence-free survival analysis confirms the benefit of adding HIPEC to interval cytoreductive surgery in patients with stage III ovarian cancer, with fewer peritoneal recurrences. These results rule out radiological bias caused by the open-label nature of the study.

PURPOSE Standard adjuvant chemotherapy for triple-negative breast cancer (TNBC) includes a taxane and an anthracycline. Concomitant capecitabine may be beneficial, but robust data to support this are lacking. The efficacy and safety of the addition of capecitabine into the TNBC adjuvant treatment regimen was evaluated. PATIENTS AND METHODS This randomized, open-label, phase III trial was conducted in China. Eligible female patients with early TNBC after definitive surgery were randomly assigned (1:1) to either capecitabine (3 cycles of capecitabine and docetaxel followed by 3 cycles of capecitabine, epirubicin, and cyclophosphamide) or control treatment (3 cycles of docetaxel followed by 3 cycles of fluorouracil, epirubicin, and cyclophosphamide). Randomization was centralized without stratification. The primary end point was disease-free survival (DFS). RESULTS Between June 2012 and December 2013, 636 patients with TNBC were screened, and 585 were randomly assigned to treatment (control, 288; capecitabine, 297). Median follow-up was 67 months. The 5-year DFS rate was higher for capecitabine than for control treatment (86.3% v 80.4%; hazard ratio, 0.66; 95% CI, 0.44 to 0.99; P = .044). Five-year overall survival rates were numerically higher but not significantly improved (capecitabine, 93.3%; control, 90.7%). Overall, 39.1% of patients had capecitabine dose reductions, and 8.4% reported grade ≥ 3 hand-foot syndrome. The most common grade ≥ 3 hematologic toxicities were neutropenia (capecitabine, 136 [45.8%]; control, 118 [41.0%]) and febrile neutropenia (capecitabine, 50 [16.8%]; control, 46 [16.0%]). Safety data were similar to the known capecitabine safety profile and generally comparable between arms. CONCLUSION Capecitabine when added to 3 cycles of docetaxel followed by 3 cycles of a 3-drug anthracycline combination containing capecitabine instead of fluorouracil significantly improved DFS in TNBC without new safety concerns.

Abstract The addition of rituximab (R) therapy significantly improves PFS in patients with relapsedl/refractory disease responding after CHOP as well as responders after R-CHOP induction (van Oers, 2005). The aim of this study was to assess, in patients with previously untreated indolent NHL, the safety, efficacy and PK of additional R therapy in responders to R-CHOP induction. Between 10/01 and 08/06, 102 patients aged 28–84 (mean 57 yr) yrs with Ann Arbor Stage III (28.4%) or IV (71.6%) indolent NHL were treated on this Phase II single-arm, open-label, multi-center, community-based trial. Baseline LDH and β2 microglobulin were above normal in 20.6% and 66.3% of patients, respectively. Treatment consisted of 6 cycles of R-CHOP (cyclophosphamide 750 mg/m2, vincristine 1.4 mg/m2, and doxorubicin 50 mg/m2 all IV on Day 1 of each 21-day cycle; prednisone 100 mg/d po Days 1–5; and R 375 mg/m2 IV 2–3 days prior to first dose of CHOP and thereafter on Day 1 of each cycle). Patients with ongoing response (CR/CRu or PR) received R 375 mg/m2 weekly x 4, repeated every 6 months x 2 yrs, for a total of up to 16 R doses, within 28 days after completion of R-CHOP. Median follow-up was 39 mos. ORR after R-CHOP was 86.3% (95% CI: 78.3, 92.1), with CR/CRu 48% (95% CI: 38.0, 58.2). As measured from initiation of R-CHOP, PFS at 2 and 3 yrs was 75.2% (95% CI: 64.0, 83.3) and 67.3% (95% CI: 54.6, 77.2), respectively. OS at 2 and 3 yrs was 92.9% (95% CI: 85.7, 96.6) and 89.4% (95% CI: 81.2, 94.2), respectively. Infusion-related toxicity with R given after R-CHOP was less frequent than seen with R-CHOP in this study. The overall incidence of serious adverse events during R therapy given after R-CHOP was 8.5%, including 3 NCI-CTC grade 3/4 events: viral encephalitis (n=1), patellar fracture (n=1) & development of colon cancer (n=1). Serum R concentrations were collected over serial timepoints from 12 patients. Both pre- and end of infusion serum R concentrations were similar across cycles 2–4 of R therapy given after R-CHOP. R concentration was higher just prior to infusion of the first R dose given after R-CHOP due to residual concentration from the R-CHOP treatment. Concentrations were very low (< 10 ug/mL) just prior to initiation of the subsequent R cycles. During R therapy given after R-CHOP, serum R concentrations were similar to those previously reported during R monotherapy treatment (Berinstein, 1998). In summary, this study demonstrated that R therapy given after R-CHOP to be generally well-tolerated, and associated with 75.2% PFS and 92.9% OS at 2 yrs, and 67.3% PFS and 89.4% OS at 3 yrs. Moreover, the current study demonstrates that PK data from R induction can be extrapolated to R given after R-CHOP. The benefit of adding additional R therapy to responders to R-chemotherapy will be addressed in the analysis of the ongoing Phase III PRIMA study, wherein patients with advanced follicular lymphoma who respond to R-chemotherapy induction are randomized to receive further R therapy vs. observation.

516 Background: Evidence suggests that docetaxel is more effective than paclitaxel, and paclitaxel is more effective when given weekly than every 3 weeks in metastatic breast cancer (BC). Methods: Eligibility included axillary lymph node positive or high-risk (tumor at least 2 cm) node-negative BC. All patients received 4 cycles of AC (doxorubicin 60 mg/m2 and cyclophosphamide 600 mg/m2) every 3 weeks, followed by either: (1) paclitaxel 175 mg/m2 every 3 weeks × 4 (P3), (2) paclitaxel 80 mg/m2 weekly × 12 (P1), (3) docetaxel 100 mg/m2 every 3 weeks × 4 (D3), or (4) docetaxel 35 mg/m2 weekly × 12 (D1). The primary comparisons included taxane (P vs. D) and schedule (every 3 weeks vs. weekly), and secondary comparisons included P3 vs. other arms. The trial had 86% power to detect a 17.5% decrease in disease-free survival (DFS) for either primary comparison, and 80% power to detect a 22% decrease for the secondary comparisons (2-sided nomimal 5% level tests corrected for multiple comparisons). Results: A total of 4,950 eligible patients were accrued. There was no difference in the primary comparisons afer 856 DFS events and 483 deaths after a median follow-up of 46.5 months at the 4th interim analysis ( www.sabcs.org , abstract 48). This is the final pre-specified analysis for the primary comparisons after 1,042 DFS events and 650 deaths (with 1,020 DFS events at this time, to be updated at the meeting). After a median followup of 60.2 months, there remains no significant difference in the hazard ratio (HR) for the taxane (1.02; p=0.73) or schedule (1.07; p=0.30) (as in the first analysis). In secondary comparisons of the standard arm (P3) with the other arms (HR > 1 favoring the experimental arms), the HRs were 1.30 (p = 0.003) for arm P1, 1.24 (p=0.02) for arm D3, and 1.09 (p=0.33) for arm D1. Analysis of interaction by hormone-receptor status will be presented. The incidence of worst grade toxicity (grade 3/4) was 24%/6% for arm P3, 24%/3% for arm P1, 21%/50% for arm D3, and 38%/6% for arm D1. Conclusions: There were no differences in DFS when comparing taxane or schedule overall. DFS was significantly improved in the weekly paclitaxel and every 3-week docetaxel arms compared with the every 3-week paclitaxel arm. [Table: see text]

LBA7007 Background: NOV-002 is a formulation of disodium glutathione disulfide (GSSG). GSSG is a naturally occurring substance that functions as a component of the glutathione (GSH) pathway, vital to the regulation of the intracellular redox state. A key function of the GSH/GSSG redox couple is to dynamically regulate protein functions, including cell signaling pathways, through the reversible formation of mixed disulfides between protein cysteines and GSH (S-glutathionylation). Based on positive results from a randomized, phase I/II study of carboplatin and paclitaxel (CP) with or without NOV-002, as well as positive results from 2 ex-U.S. phase II studies with cisplatin-based chemotherapy, an international phase III randomized trial was launched. Methods: Patients with advanced NSCLC (stages wet IIIB and IV, inclusive of all histological subtypes) were eligible if they had a PS of 0-1 and adequate end-organ function. Patients with CNS metastases were excluded. Eligible patients were randomized to C (AUC 6), P (200 mg/m2), and NOV-002 (Group A) or C and P alone (Group B). NOV-002 was administered as two-60 mg IV boluses on day -1 of cycle 1 and as one IV bolus on day 1 of each cycle, followed by daily 60-mg subcutaneous injections. A total of 725 events were required to detect a difference in overall survival (OS) from 10.0 to 12.5 months with 85% power and a two-sided significance level of 0.05. No interim analysis was performed. Results: From 11/06 until 9/09, 903 patients were randomized, with target enrollment reached in March 2008. Patient characteristics for Groups A and B were as follows: stage IV (91.5/90.8%), PS 1 (76.6/72.6%), male (69.9/72.4%), never smoker (22.3/19.1%) median age (59.6/59.5), and histology (adenocarcinoma [40.0/36.8%] squamous [41.2/40.8%]). The median overall survival for Groups A and B was 10.2/10.8 months (p = 0.375), median progression-free survival was 5.3/5.6 months, objective response rate was 26.6/26.0% and 54/53% of patients completed at least six cycles of chemotherapy. Major toxicities for Groups A and B included grade 3/4 neutropenia (29.7/26.3%), febrile neutropenia (2.2/1.8%), grade 3/4 thrombocytopenia (3.8/2.9%), and grade 3/4 neuropathy (2.9/2.4%). Adverse events resulting in death in Groups A and B were reported in 5.6 and 3.1%, respectively. Conclusions: The addition of NOV-002 to CP does not improve overall survival in patients with advanced NSCLC. NOV002 does not appear to add to the overall toxicity of chemotherapy. [Table: see text]

8567 Background: Vemurafenib (vem) has been FDA approved for the treatment of unresectable or metastatic BRAFV600E mutated melanoma since August 2011 based on results of a randomized phase III study (treatment-naive) and a single arm phase II study (previously treated). We report results of an expanded access study that allowed appropriate patients (pts) to receive vem until the drug was approved. Methods: Eligible pts had metastatic melanoma with a BRAFV600E mutation as detected by the cobas 4800 BRAFV600 Mutation Test. Enrolled pts received oral vem 960 mg b.i.d. Adverse events (AEs) were evaluated for vem-related toxicities; tumor responses were assessed using RECIST 1.1. Results: 29 US sites screened 745 pts and enrolled 374 from December 2010 until October 2011. The following results are based on a median follow up time and treatment duration of 2 months. At baseline, mean age of pts was 54 y with 22% of pts ≥65 y; 75% had stage M1c disease; 29% had received radiotherapy for brain metastases. 19% of pts were ECOG PS 2 or 3; 71% of pts had prior systemic therapy for metastatic melanoma (21% 1 regimen; 50% ≥2 regimens). 50 pts had prior adjuvant treatment. At data cut-off, 243 pts had sufficient follow-up time for tumor assessment. In this group, the unconfirmed overall response rate was 52% (95% CI, 46 to 59). The median time to response was 1.8 months. Based on 240 pts with available ECOG PS status at time of analysis, response rate was 53% for pts with ECOG PS 0 or 1 (n=209), and 45% for pts with ECOG PS 2 or 3 (n=31). 370 pts were evaluable for safety analysis. The most common vem-related AEs were rash (36%), arthralgia (33%) and fatigue (21%) with the majority (~90%) of grade 1 or 2. 25 vem-related serious AEs were reported in 5.4% of pts with a slightly higher rate of pts with ECOG PS 2 or 3 (8.7%) compared to ECOG PS 0 or 1 (4.7%). 18% of pts missed at least one dose and 11% of pts required dose reduction of at least one level due to AEs. Conclusions: This expanded access study, with its limited follow-up time, confirms the established rapid and high tumor response rate with vem. No new safety signals were detected. Compared to the overall population, pts with an ECOG PS 2 or 3 demonstrated a similar benefit.

TPS4692^ Background: The phase III TROPIC study (NCT00417079) reported a significant improvement in overall survival (OS) for cabazitaxel (Cbz) + prednisone (P;CbzP) (25 mg/m2 IV Q3W/10 mg PO QD) vs mitoxantrone (M) + P (MP) (median OS 15.1 vs 12.7 mos; HR 0.70; P < 0.0001) in pts with mCRPC (also known as hormone-refractory prostate cancer) previously treated with a D-containing regimen. CbzP is approved by the FDA, EMA and other health authorities for the treatment of pts with mCRPC that has progressed after a D-containing regimen. Cbz toxicity is consistent with other taxanes; compared with M, more hematologic toxicities are reported (primarily Grade 3–4 neutropenia). Phase I/II studies identified 20 and 25 mg/m2 as recommended doses; 25 mg/m2 was selected for the phase III TROPIC study. As pooled data show Grade 3–4 neutropenia incidence is lower with Cbz < 25 mg/m2 (61%) vs ≥ 25 mg/m2 (74%), it is of interest to assess if reducing the Cbz approved dose in mCRPC lessens hematologic toxicity and is non-inferior in terms of efficacy. Methods: PROSELICA (NCT01308580) is a randomized, open-label, multinational, phase III study comparing 20 mg/m2 and 25 mg/m2 Cbz for efficacy and tolerability. Pts with a life expectancy > 6 mos, ECOG PS ≤ 2, histologically/cytologically confirmed metastatic prostate adenocarcinoma resistant to hormone therapy and previously treated with a D-containing regimen are eligible. Pts are randomized 1:1 to receive Cbz 20 mg/m² or 25 mg/m² IV Q3W + P 10 mg PO QD, treated until disease progression, unacceptable toxicity or withdrawal of consent (max 10 cycles), and stratified according to ECOG PS, measurable disease (yes/no) and region. The primary endpoint is OS (non-inferiority design). Secondary endpoints include safety, progression-free survival (PCWG2 criteria), PSA and pain progression and response, tumor response in pts with measurable disease and health-related quality of life. Cbz PK and pharmacogenomics will be assessed in pt subgroups. Planned enrollment is 1,200 pts. Study start was in May 2011; as of Jan 2012, 270 pts had been enrolled. The first DMC meeting recommended continuing the study without change.
