The Impact

683 Background: In the RAS wt population of TAILOR, adding cet to 1L F significantly improved progression-free survival (PFS), overall survival (OS), and overall response rate (ORR). In this subgroup analysis, we evaluate the impact of TL. Methods: TAILOR is a randomized phase 3 trial that includes a modified intention-to-treat (mITT) population of 393 pts from China with RASwt mCRC treated with F ± cet. The primary endpoint of TAILOR is PFS; key secondary endpoints include OS and ORR. TL was categorized in evaluable pts in the mITT population (left-sided = splenic flexure, descending colon, sigmoid colon, and rectum; right-sided = appendix, cecum, ascending colon, hepatic flexure, ± transverse colon). Results: Efficacy data for the TL subgroups are summarized in the table. Additionally, the prognostic effect of TL (left- vs right-sided) within the treatment arms could be shown for PFS (HR = 1.72; p = .007), OS (HR = 1.84; p = .002), and ORR (OR = 0.40; p = .014) in the cet + F arm and PFS (HR = 1.97; p = .002), OS (HR = 1.43; p = .073), and ORR (OR = 0.41; p = .028) in the F arm. Regarding the potential predictive value of TL, the p values for the interaction between TL and treatment are: PFS (.676), OS (.339), and ORR (.986). Conclusions: In TAILOR, adding cet to 1L F clearly benefitted RAS wt pts with left-sided tumors in terms of PFS, OS, and ORR; for pts with right-sided tumors, the HRs for PFS and the ORs for ORR also consistently suggested a benefit showing a trend in favor of cet.

The Impact

747 Background: In the RAS wt population of APEC, q2w cetuximab combined with 1L FOLFOX or FOLFIRI achieved a best confirmed overall response rate (BORR), median progression-free survival (PFS), and median overall survival (OS) similar to those reported in prior 1L pivotal studies involving weekly (qw) cetuximab. In this hypothesis-generating subgroup analysis, we evaluated the impact of TS in APEC study patients with RAS wt mCRC. Methods: APEC was a nonrandomized phase 2 trial conducted in the Asia-Pacific region, with BORR as the primary endpoint. Patients with KRAS exon 2 wt tumors received q2w cetuximab + investigator’s choice of FOLFOX or FOLFIRI; subsequent analyses considered patients who were RAS wt ( KRAS/ NRAS, exons 2-4). TS was categorized in evaluable patients with RAS wt tumors (left [L]-sided = splenic flexure, descending colon, sigmoid colon, and rectum; right [R]-sided = appendix, cecum, ascending colon, hepatic flexure, and transverse colon). Results: Among 167 patients with RAS wt mCRC, 159 were evaluable for TS; 130 (81.8%) had L-sided and 29 (18.2%) had R-sided mCRC. Baseline characteristics in the TS subgroups reflected the known differences between L- and R-sided mCRC. Efficacy data for the TS subgroups are summarized in the table. Conclusions: Consistent with prior 1L pivotal studies involving qw cetuximab, a prognostic effect of TS in patients receiving 1L q2w cetuximab was confirmed in APEC. BORR remained ≥50% in patients with R-sided mCRC, in line with prior evidence that use of cetuximab may be appropriate when tumor shrinkage/cytoreduction is the goal. These hypothesis-generating data also raise the possibility of synergy between cetuximab and, in particular, irinotecan for PFS and OS in patients with R-sided tumors, although numbers are small.

200 Background: In the phase 3 PREVAIL trial, enzalutamide (ENZA), an androgen receptor inhibitor, improved overall survival (OS) and radiographic progression-free survival (rPFS) relative to placebo (PBO) in chemotherapy-naïve men with mCRPC. Methods: PREVAIL randomized 1,717 patients (pts) with asymptomatic or minimally symptomatic chemotherapy-naïve mCRPC 1:1 to ENZA 160 mg daily or PBO. Coprimary endpoints were OS and rPFS. This prespecified analysis evaluated the impact of age (≥ 75 vs < 75 years) on efficacy and safety. Results: In PREVAIL, 609 (35%) pts were aged ≥ 75 years. This older subset had several poorer baseline prognostics relative to those aged < 75 years: worse ECOG performance status (ECOG 1: 45.0% vs 24.7%), higher prostate-specific antigen (PSA; 73.3 vs 37.3 ng/mL) and more cardiovascular disease (26.9% vs 16.5%). In both older and younger pts, ENZA improved OS, rPFS and time to PSA progression (Table). Pts aged ≥ 75 years in both the ENZA and PBO groups combined had a higher rate of grade ≥ 3 adverse events (46% vs 37% in younger pts) and among enzalutamide-treated men more older pts reported falls (any grade; ENZA 19% and PBO 8%) than younger pts (ENZA 7% and PBO 4%). Fewer pts ≥ 75 years received subsequent antineoplastic therapies. Conclusions: In PREVAIL, efficacy outcomes in elderly (≥ 75 years) and younger (< 75 years) pts with chemotherapy-naïve mCRPC were comparable and pts consistently benefited from ENZA treatment. Safety with ENZA was similar in both age groups, although older pts reported a higher incidence of falls and received fewer subsequent antineoplastic therapies.

492 Background: 3-drug chemotherapy (CT) + BEV (cFOLFOXIRI-BEV) significantly improved efficacy vs FOLFIRI-BEV for 1L mCRC tx, but safety and the impact of subsequent fluoropyrimidine-BEV maintenance tx require further definition. The phase 2 STEAM (NCT01765582) trial assessed efficacy of 1L cFOLFOXIRI-BEV vs FOLFOX-BEV and safety of alternating 2-drug CT (FOLFOX and FOLFIRI) + BEV tx monthly in a sequential sFOLFOXIRI-BEV regimen. Methods: Pts with unresectable, previously untreated mCRC were randomized 1:1:1 to BEV-containing (5 mg/kg) arms (cFOLFOXIRI, sFOLFOXIRI [alternating FOLFOX and FOLFIRI every 4 weeks {q4w}], or FOLFOX q3w) in a 4–6 month induction phase, followed by BEV-containing maintenance tx. Stratification factors included extent of metastatic disease and tumor location. Primary objectives: 1L ORR, 1L progression-free survival (PFS), safety. Secondary objectives: resection and conversion to resectable disease rates, time to 2L PFS, overall survival. ORR was tested with a 1-sided alpha of 5%; tx arms were compared with a stratified 1-sided Cochran-Mantel-Haenszel test. PFS was analyzed descriptively. Results:Among 280 enrolled pts (median age, 57.5 yrs), 186 remainined in the study on July 1, 2015. Efficacy and safety are shown (see Table). Conclusion: While not statistically significant, there was a trend of increased ORR with cFOLFOXIRI-BEV vs FOLFOX-BEV in 1L mCRC tx. Analysis of PFS is ongoing. All 3 regimens were well tolerated. Clinical trial information: NCT01765582. [Table: see text]

3503 Background: 80405 found no OS or Progression Free Survival (PFS) difference when bevacizumab (BV) or cetuximab (Cet) was added to 1st-line FOLFOX or FOLFIRI in All RAS wild type (wt) mCRC pts. There was a significant 1° side by biologic interaction (P int: OS = 0.008, PFS = 0.001) favoring pts with left-sided (L) 1°. Analyses of 1° tumors beyond All RAS includes Consensus Molecular Subtype (CMS), BRAF and MSI. (CMS results - see Lenz et al; BRAF -see Innocenti et al) We asked whether 1° tumor location - L vs right (R) - is an independent prognostic marker when these other molecular features are considered. Methods: We used a Cox proportional hazard model stratified by prior XRT and +/- adjuvant chemo; adjusted for age, gender, synchronous vs metachronous, CMS, MSI and BRAF status. Pts with transverse (T) tumors were excluded in this analysis. Results: Sidedness was determined in 782 pts (L - 472; R - 256; T -54). Molecular data from 728 pts (with L - and R-sided 1°s) was available as follows: KRAS -- 291, NRAS -393, BRAF - 393, MSI - 378, CMS - 533. L vs R mOS: 32.9 v 19.6 months (mo) (p < 0.0001). See Table for OS results in All RAS / BRAF wt and BRAF mutant (mut) pts. Sidedness (R vs L) is an independent prognostic marker even after adjusting for all these molecular features: HR = 1.392 (1.032, 1.878), p = 0.031. Conclusions: Primary tumor location is an independent prognostic factor when adjusted for age, gender, synchronous/metachronous, CMS, MSI and BRAF status. We are exploring clinical variables such as tumor burden, metastatic sites and measurability of disease in an attempt to explain the impact of sidedness. Support: U10CA188021, U10CA180882.

TPS3619 Background: Cancer stem cells are considered to be fundamentally important for resistance to therapy, recurrence and metastasis. Napabucasin is a first-in-class cancer stemness inhibitor in development identified by its ability to inhibit STAT3-driven gene transcription and spherogenesis of cancer stem cells (Li et al, PNAS 112(6):1839, 2015). Preclinically, napabucasin sensitizes cancer cells to chemotherapeutics, including 5-FU and irinotecan. Encouraging anticancer activity in advanced CRC was observed in a phase Ib/II (Bendell et al, GI ASCO 2017) study of 63 pts with disease control rate (DCR) of 93% (28/30) and overall response rate (ORR) of 33% (10/30) in FOLFIRI-naïve pts who have had an on-study RECIST evaluation. On the basis of these data, a phase III trial is being conducted in North America, Europe, Australia, and Asia. Methods: This study (ClinicalTrials.gov NCT02753127) will assess the efficacy of napabucasin+FOLFIRI vs FOLFIRI in pts with mCRC (n = 1250). Addition of bevacizumab (bev) is permissible per investigator choice. Pts must have failed 1 prior line of therapy with oxaliplatin and a fluoropyrimidine +/- bev for metastatic disease. Pts are randomized 1:1 to receive napabucasin 240 mg PO BID plus FOLFIRI bi-weekly, or FOLFIRI bi-weekly (bev may be added to FOLFIRI by investigator choice) and stratified by geography, time to progression on 1st-line therapy, RAS mutation status, bev as part of study treatment and primary tumor location. Treatment will continue until disease progression, or another discontinuation criterion. Primary endpoint is overall survival (OS) in the general study population (ITT) (HR 0.80 for OS improvement from 12.54 to 15.68 months); secondary endpoints include OS in the biomarker positive (biomarker+) population, progression free survival (PFS) in the ITT population, PFS in biomarker+ population, ORR and DCR in the ITT and in biomarker+ populations, safety and quality of life. Also, blood and tumor archival tissue will be assessed for PK and biomarker analyses. Global enrollment is underway. Clinical trial information: NCT02753127.

Abstract Background: Lanreotide autogel is a somatostatin analog (SSA) approved for the treatment of acromegaly in 73 countries worldwide; however, it is not yet approved in China. The aim of this study was to evaluate the efficacy and safety of lanreotide autogel compared with lanreotide 40 mg prolonged release (PR) in Chinese patients with active acromegaly. Methods: LANTERN was a Phase 3, randomized, open-label, non-inferiority study. Patients with active acromegaly who had undergone surgery ≥3 months prior, or were unlikely or unable to undergo surgery, were treated with lanreotide autogel 60/90/120 mg (monthly deep subcutaneous injection) or lanreotide 40 mg PR (intramuscular injection every 7, 10, or 14 days) for 32 weeks. Primary endpoint was mean change-from-baseline in age-adjusted insulin-like growth factor-1 (IGF-1) standard deviations scores (SDS) at the end-of-study. Secondary endpoints included: growth hormone (GH) levels ≤2.5 µg/L or ≤1.0 µg/L, ≥20% reduction in tumor volume (TV) and safety. Results: In total, 128 patients were randomized and received study treatment. Lanreotide autogel was non-inferior to lanreotide 40 mg PR: treatment difference (95% CI) for IGF-1 SDS between groups was −0.32 (−0.74, 0.11; per protocol population) and −0.27 (−0.63, 0.09; intention-to-treat [ITT] population), respectively. Reductions in IGF-1 (−6.453 vs −7.003) and GH levels (−9.548 µg/L vs −13.182 µg/L), and the proportion of patients with ≥1 acromegaly symptom (−20.3% vs −32.5%) were observed from baseline to end-of-study in lanreotide autogel and lanreotide 40 mg PR groups, respectively. In the lanreotide autogel group, 45.5% (25/55) patients achieved ≥20% reduction in TV compared with 50.9% (25/53) in lanreotide 40 mg PR group (ITT). Safety profiles were similar in both treatment groups. Conclusions: Lanreotide autogel was non-inferior to lanreotide 40 mg PR in Chinese patients with active acromegaly after 32 weeks of treatment.

3515 Background: The primary analysis of DREAM demonstrated that a maintenance therapy (MT) with bevacizumab (Bev) + EGFR TKI erlotinib (E) significantly improved progression-free survival (PFS) after a 1st-line Bev-based induction therapy (IT) in patients (pts) with unresectable mCRC. Methods: Pts were randomized to MT after an IT with FOLFOX-bev or XELOX-bev or FOLFIRI-bev between Bev alone (Bev 7.5 mg/kg q3w; arm A) or Bev+E (Bev 7.5 mg/kg q3w, E 150 mg/d ; arm B) until PD or unacceptable toxicity. Primary endpoint was PFS on MT. Secondary endpoints included PFS from inclusion, overall survival (OS) and safety. The impact of KRAS tumor status on treatment efficacy was evaluated in an exploratory analysis. Results: 700 pts were registered and 452 pts were randomized (228 in arm A, 224 in arm B). KRAS status was available for 413/452 (91%) pts. The median duration of MT was 3.6 m. Results for MT are presented below (Table). In the registered population, median OS was 24.9m (22.5 – 27.3). Conclusions: Maintenance treatment with bev + erlotinib increases PFS over maintenance with bev alone in pts with mCRC but does not prolong OS. Further follow-up will determine the impact of 2nd or 3rd line anti-EGFR Mabs in this study. Contrasting with anti-EGFR Mabs, KRAS tumor status is not mandatory to select pts with mCRC for treatment with erlotinib. Clinical trial information: NCT00265824. [Table: see text]

638 Background: HA is a major component of the tumor microenvironment (TME) in PDA. PEGPH20 degrades tumor HA, remodeling the TME. In PDA models, PEGPH20 has shown antitumor activity and increased TME delivery of anticancer agents to improve efficacy. A randomized phase 2 study showed promising results for PEGPH20+AG (PAG) in mPDA and identified HA accumulation as a biomarker. We present results from a phase 3 study (NCT02715804) of PAG for pts with HA-high mPDA. Methods: Pts ≥18 years with untreated HA-high mPDA were randomized (stratified by geographic region) 2:1 to PAG or placebo+AG (AG). HA status was prospectively determined with VENTANA HA RxDx Assay, with HA-high defined as ≥50% staining of a tumor sample. Treatment was administered IV in 4-wk cycles (3 wks on, 1 wk off) until progression or intolerable adverse events (AEs): PEGPH20 3.0 µg/kg twice wkly for Cycle 1 and once wkly (QW) thereafter, A 125 mg/m2 QW and G 1000 mg/m2 QW. Prophylactic enoxaparin 1 mg/kg was given daily for thromboembolism (TE) risk. The primary endpoint was overall survival (OS); secondary endpoints included progression-free survival (PFS), objective response rate (ORR) and safety. Response was independently assessed per RECIST v1.1. The estimated sample size was ~500 pts to detect a hazard ratio (HR) for OS of 0.67 (93% power, 2-sided α = 0.05) after 330 deaths. Results: As of 20 May 2019, 494 pts were randomized with 492 (327 for PAG and 165 for AG) included in ITT analyses (2 pts excluded due to site violations). Baseline characteristics were balanced for PAG vs AG. After 330 deaths, median OS for PAG vs AG was 11.2 vs 11.5 mo (HR 1.00, 95% CI 0.80–1.27; P = 0.97); median PFS was 7.1 vs 7.1 mo (HR 0.97, 95% CI 0.75–1.26); confirmed ORR was 34% vs 27%. Grade (G) 3+ AEs (PAG vs AG) included neutropenia (44% vs 47%), thrombocytopenia (21% vs 16%) and fatigue (16% vs 10%); G3+ rates were 6% vs 7% for TE events, 5% vs 2% for bleeding events and 13% vs 5% for musculoskeletal events. Conclusions: PAG did not improve clinical outcomes vs AG. The PAG safety profile was consistent with that of previous studies. Clinical trial information: NCT02715804.

Abstract Background In the randomised Phase 3 IMpassion130 trial, atezolizumab combined with nab-paclitaxel (atezo + nab-P) in 902 patients with triple-negative breast cancer (TNBC) showed prolonged progression-free survival (PFS) in both the intention-to-treat (ITT) population and programmed death-ligand 1 (PD-L1)–positive subgroup compared with placebo plus nab-P (plac + nab-P). This study assessed the efficacy and safety of atezo + nab-P in the IMpassion130 Japanese subpopulation. Methods Eligible patients had unresectable locally advanced or metastatic TNBC previously untreated with chemotherapy for metastatic disease. Patients were randomised 1:1 to receive either atezo + nab-P or plac + nab-P. Co-primary endpoints were investigator-assessed PFS and overall survival (ITT population and PD-L1–positive subgroup). These were also assessed in the Japanese subpopulation. Results There were 65 Japanese patients (34 atezo + nab-P; 31 plac + nab-P). The PD-L1–positive subgroup included 25 patients (12 atezo + nab-P; 13 plac + nab-P). Median PFS was 7.4 months (atezo + nab-P) versus 4.6 months (plac + nab-P; hazard ratio [HR], 0.47; 95% CI, 0.25–0.90). In the PD-L1–positive subgroup, median PFS was 10.8 months (atezo + nab-P) versus 3.8 months (plac + nab-P; HR, 0.04; 95% CI, &lt;0.01–0.35). Safety results in the Japanese subgroup were consistent with those in the overall population. The Japanese subgroup had a lower incidence of adverse events leading to treatment withdrawal than the overall population. More patients in the atezo + nab-P arm had neutrophil count decreases and stomatitis than patients in the plac + nab-P arm. Conclusions Atezo + nab-P efficacy in Japanese patients was consistent with the overall IMpassion130 population. No new safety signals were observed, and tolerability was consistent with that of the overall population.

Abstract The Spanish Myeloma Group conducted a trial to compare bortezomib/thalidomide/dexamethasone (VTD) versus thalidomide/dexamethasone (TD) versus vincristine, BCNU, melphalan, cyclophosphamide, prednisone/vincristine, BCNU, doxorubicin, dexamethasone/bortezomib (VBMCP/VBAD/B) in patients aged 65 years or younger with multiple myeloma. The primary endpoint was complete response (CR) rate postinduction and post–autologous stem cell transplantation (ASCT). Three hundred eighty-six patients were allocated to VTD (130), TD (127), or VBMCP/VBAD/B (129). The CR rate was significantly higher with VTD than with TD (35% vs 14%, P = .001) or with VBMCP/VBAD/B (35% vs 21%, P = .01). The median progression-free survival (PFS) was significantly longer with VTD (56.2 vs 28.2 vs 35.5 months, P = .01). In an intention-to-treat analysis, the post-ASCT CR rate was higher with VTD than with TD (46% vs 24%, P = .004) or with VBMCP/VBAD/B (46% vs 38%, P = .1). Patients with high-risk cytogenetics had a shorter PFS and overall survival in the overall series and in all treatment groups. In conclusion, VTD resulted in a higher pre- and posttransplantation CR rate and in a significantly longer PFS although it was not able to overcome the poor prognosis of high-risk cytogenetics. Our results support the use of VTD as a highly effective induction regimen prior to ASCT. The study was registered with http://www.clinicaltrials.gov (NCT00461747) and Eudra CT (no. 2005-001110-41).
