Background: In the PROSELICA phase III trial (NCT01308580), cabazitaxel 20 mg/m2 (CABA20) was non-inferior to cabazitaxel 25 mg/m2 (CABA25) in mCRPC patients previously treated with docetaxel (DOC). The present post hoc analysis evaluates how the type of progression at randomization affected outcomes. Methods: Progression type at randomization was defined as follows: PSA progression only (PSA-p; no radiological progression (RADIO-p), no pain), RADIO-p (±PSA-p, no pain), or pain progression (PAIN-p, ±PSA-p, ±RADIO-p). Relationships between progression type and overall survival (OS), radiological progression-free survival (rPFS), and PSA response (confirmed PSA decrease ≥ 50%) were analyzed. Results: All randomized patients (n = 1200) had received prior DOC, and 25.7% had received prior abiraterone or enzalutamide. Progression type at randomization was evaluable in 1075 patients (PSA-p = 24.4%, RADIO-p = 20.8%, PAIN-p = 54.8%). Pain progression was associated with clinical and biological features of aggressive disease. Median OS from CABA initiation or date of mCRPC diagnosis, all arms combined, was shorter in the PAIN-p group than in the RADIO-p or the PSA-p groups (12.0 versus 16.8 and 18.4 months, respectively, p < 0.001). In multivariate analysis, all arms combined, PAIN-p was an independent predictor of poor OS (HR = 1.44, p < 0.001). PSA response, rPFS, and OS were numerically higher with CABA25 versus CABA20 in patients with PAIN-p. Conclusions: This post hoc analysis of the PROSELICA phase III study shows that pain progression at initiation of CABA in mCRPC patients previously treated with DOC is associated with a poor prognosis. Disease progression should be carefully monitored, even in the absence of PSA rise.

5014 Background: GSTP1 inactivation is associated with CpG island hypermethylation in > 99% prostate cancers. Detection of circulating mGSTP1 DNA predicts response to DTX and overall survival (OS) in phase I/II mCRPC cohorts. This post hoc analysis of a phase III study aims to test the association between circulating mGSTP1 DNA levels and outcomes. Methods: The phase III SYNERGY study tested DTX +/- custirsen as 1st line chemotherapy in mCRPC (n = 1022) with no OS benefit in the experimental arm. Serum samples were taken at baseline (BL) and preC3 of DTX +/- custirsen from 600 patients (pts) enrolled on the SYNERGY study. mGSTP1levels in free DNA were measured using a sensitive methylation specific PCR assay and correlated with PSA response, time to PSA progression (TTP) and OS. Results: On interim analysis of 300 pts, serum mGSTP1 was detectable at BL in 80% and preC3 in 44%. Undetectable preC3 mGSTP1 correlated with a ≥30% fall in PSA within 3m of starting DTX (p < 0.001). Detectable BL and preC3 mGSTP1 predicted shorter TTP after DTX (BL; HR 1.6 95%CI 1.1-2.3; p = 0.01 and preC3 HR 2.2 95%CI 1.6-2.9; p < 0.001). Detectable mGSTP1 at both time points predicted shorter OS (BL; median OS 18.4 vs 33.1m, HR 2.4 95%CI 1.6-3.7; p < 0.001 and preC3; median OS 13.9 vs 29m, HR 2.7 95%CI 2.0-3.6; p < 0.001). In those with detectable BL mGSTP1, 50% had undetectable preC3 mGSTP1 predicting > 30% fall in PSA within 3m (p < 0.001), improved TTP (HR 0.40 95%CI 0.29-0.57; p < 0.001) and improved OS (25.2 vs 13.9 m HR 0.38 95%CI 0.28-0.51; p < 0.001). On multivariable analysis including Hb, Karnofsky PS, LDH, PSA and visceral metastases, detectable preC3 mGSTP1 independently predicted shorter TTP (HR 1.9 95%CI 1.4-2.6; p < 0.001). Detectable mGSTP1at both time points independently predicted OS (BL; HR1.8 95%CI 1.2-2.8; p = 0.006 and preC3; HR 2.2 95%CI 1.6-3.0; p < 0.001). Results from the full cohort of 600 pts will be available for presentation at the meeting. Conclusions: This study should validate circulating mGSTP1 DNA as a marker of therapeutic benefit and prognosis in men with mCRPC receiving DTX and could be utilized for clinical management.

460 Background: We report a post hoc, exploratory analysis of pts with BL ML number and LL data who received nal-IRI+5-FU/LV, nal-IRI or 5-FU/LV in NAPOLI-1, a pivotal, phase 3 trial (NCT01494506). nal-IRI+5-FU/LV increased median OS (mOS) vs 5-FU/LV (6.1 vs 4.2 mo [HR=0.67; p=0.012]). Methods: ML (1, 2, 3, >3) and LL were recorded (local investigator) at BL. Pts with >1 LL were counted for each location. Results: 354 of 417 ITT pts had measurable BL ML and 1,080 LL were recorded. There was no clear trend in the percentage of pts with KPS ≥80 in 1- >3 ML (range 87%-95%) or LL (range 89%-94%) subgroups. ML 1 (n=81), 2 (n=65) and 3 (n=24) subgroups were small. nal-IRI+5-FU/LV significantly improved mOS vs. 5-FU/LV in pts with 2/>3 ML (n=184/24); nal-IRI+5-FU/LV had numerically higher mOS vs. 5-FU/LV for all LL (Table). nal-IRI+5-FU/LV had favourable median PFS (mPFS) vs. 5-FU/LV in pts with 1–>3 ML (range 2.0-4.2 vs. 1.4-1.9 mo; HR range 0.35-0.88) and for all LL (range 2.8-4.2 vs. 1.4-2.0 mo; HR range 0.39-0.55). Conclusions: Low pt numbers across groups and repeat counting of pts in LL subgroups preclude firm conclusions on treatment efficacy, pending further analyses. Allowing for these limitations, we detected no clear prognostic effect on outcomes of higher BL ML number or LL in NAPOLI-1 ITT pts. nal-IRI+5-FU/LV improved mOS vs. 5-FU/LV in some ML groups and across LL groups; improvement in mPFS vs. 5-FU/LV in the ITT population was maintained in all subgroups.

85 Background: Total gastrectomy for gastric cancer significantly reduces body weight, especially lean body mass (LBM), through surgical stress and decrease of the calorie intake. Eicosapentaenoic acid (EPA)-enriched enteral nutrition (EPA-EN) could modulate immune function and limits catabolism. In our phase III study to compare perioperative standard diet with or without EPA-EN, additional EPA-EN did not contribute to prevent weight loss or LBM. Recently, 5% or more LBM loss after surgery was reported to impair compliance of post-operative S-1 adjuvant chemotherapy. This post hoc study explored whether additional EPA-EN prevented meaningful loss of LBM for compliance of adjuvant chemotherapy after surgery. Methods: Key entry criteria of this phase III study was (1) histologically proven adenocarcinoma of the stomach, (2) clinical T1-T4a and M0, (3) R0 resection is possible by total gastrectomy, (4) sufficient oral intake, and (5) sufficient organ function. The patients were randomized to Group A: no supplementation with oral nutrients (standard diet) or Group B: standard diet with oral supplementation of ProSure including 600 kcal with 2.2 g EPA for 7 days before surgery and for 21 days after surgery. For both groups, patients underwent total gastrectomy with Roux-en Y reconstruction. Results: A total of 127 patients (Group A: 63, Group B: 64) were enrolled in the study. All background factors were well balanced between the both groups. Median relative performance of supplement in group B was 100% before surgery and 54% after surgery. 5% or more LBM loss at 1 month after surgery was observed in 44 patients (80.0%) in group A and in 37 patients (67.3%) in group B (p = 0.194), while that at 3 months after surgery was found in 51 patients (91.1%) in group A and in 43 patients (76.8%) in group B (p = 0.070). Conclusions: Perioperative standard diet with EPA-enriched enteral nutrition tended to prevent meaningful loss of LBM after total gastrectomy. Further analysis is required whether perioperative EPA enriched EN improve compliance of S-1 adjuvant chemotherapy after total gastrectomy. Clinical trial information: UMIN000006380.

379 Background: We report an exploratory, post hoc subgroup analysis in pts with BPI and BAU data receiving nal-IRI+5-FU/LV, nal-IRI or 5-FU/LV in NAPOLI-1 (NCT01494506). In this pivotal trial, nal-IRI+5-FU/LV improved median OS (mOS) vs. 5-FU/LV (6.1 vs. 4.2 mo [HR=0.67; p=0.012]). Methods: BPI/BAU included an average of 3-7 days pt-recorded data before randomisation. Greater values indicated greater pain for BPI using a 100 mm visual analogue scale. BAU was converted to morphine equivalent mg/day. Results: Of 417 ITT pts, 295 had BPI and 299 had BAU data. Mean and median BPI were 28.6 and 25.0, respectively, and BAU were 33.3 and 8.1 mg/day, respectively. The percentage of pts with KPS ≥ 80 was higher in ≤ mean/≤ median (n=159/148) BPI groups vs. > mean/> median (n=136/147) BPI groups (96-97 vs. 83%) and in ≤mean/≤median (n=207/150) BAU groups vs. > mean/> median (n=92/149) BAU groups (95-97 vs. 82-85%). mOS and median PFS (mPFS) were higher for nal-IRI+5-FU/LV vs 5-FU/LV in all groups, with ≤ mean/≤ median BPI or BAU showing better outcomes vs. > mean/> median BPI or BAU (Table). Conclusions: BPI and BAU appear to have a prognostic effect on outcomes in mPDAC pts in the NAPOLI-1 study. No predictive effect was observed, with nal-IRI+5-FU/LV showing higher mOS vs. 5-FU/LV in all groups. Clinical trial information: NCT01494506. [Table: see text]
