e11545 Background: NVBO has shown high activity and good safety profile when given as single agent chemotherapy (CT) for MBC. Oral CT formulations allow maintenance of quality of live and minimal interference with a normal lifestyle. Methods: Main inclusion criteria for this retrospective study were: Histologically or citologically confirmed MBC, no more than 1 prior CT line for MBC; prior (neo)adjuvant CT, hormonetherapy or radiotherapy allowed; adequate bone marrow, kidney and liver function. The study protocol was approved by an ethics committee. Data was collected from patients (p) treated between Apr/2006 and Dec/2010 with NVBO 60 mg/m2 weekly until progression or unacceptable toxicity. 70 patients fulfilled the inclusion criteria. Patient’s characteristics were: Median age, 65 years (range 38-82); >75 years old, 20%; ECOG PS 0-1 in 91% p and PS 2 in 9%; ER+ &/or PR+, 41 p (59%); >2 metastatic sites in 61%; prior (neo)adjuvant CT in 48 p (69%); prior hormonotherapy, 44 p (63%). Measurable disease in 68 p (97%). 1 p received trastuzumab concomitantly. Results: Median number of administrations (a) 11 (range 2-36). 1st/2nd line: 41%/59%. We analyzed 923 a. Dose delayed or reduced due to hematological toxicity in 2.7% a, related non-hematological toxicity in 0.3% a. Dose was reduced in 1% a. Hematological toxicities (%a): neutropenia grade (g) 3, 0.8%; febrile neutropenia 1 p who died due to septic shock after 9 a. Non-hematological toxicities (%a): pain g 3-4, 0.5%; constipation g 3-4, 0.3%; ileus paraliticus g 3, 0.1%; infection g 3, 0.1%; nausea/vomiting g4, 0.1% . 68 p were evaluable for response. 1 CR (1.5%), 19 PR (27.9%) and 16 SD (23.5%) were reported. Objective response (OR) rate 29.4% [CI 95%: 19%-41.7%]. Median progression free survival 4 m [CI 95%, 2.3-5.8]. Median survival has not been reached at the time of analysis. Conclusions: Our findings confirm the consistently produced clinically meaningful efficacy of single agent NVBO for MBC. We observed a favorable safety profile with a particular low incidence of myelosupression and alopecia. We consider that oral vinorelbine is a suitable 1st or 2nd-line treatment for convenient administration in an outpatient environment in selected p with MBC.

575 Background: VG has shown to be efficacious and safe in MBC in pts previously treated with AT. This study compared treatment (TT) V with the combination of VG. Primary objective was progression free survival (PFS). Methods: pts previously treated with AT, aged ≥18, ECOG ≤ 2, were randomized to V: 30 mg/m2 day (d) 1, d8, or VG 30/1200 mg/m2 d1, d8, both every 21 days until disease progression. Stratification criteria were previous lines of TT for MBC (0 vs.1 vs.2) and visceral disease (yes vs. no). 126 pts per arm were needed to demonstrate a prolongation in PFS of 2 months (m) (from 3 to 5; HR = 1.67; α and β errors 0.05 and 10). Results: 252 pts (127 V and 125 VG) were recruited between 2001 and 2005. Arms were well balanced: median age was 57 years; median number of metastatic sites 2; visceral disease was present in 75% of pts; 17%, 53% and 29% of pts received study TT as first, second and third line respectively. Median number of cycles were 4 (1–21) in V and 6 (1–26) in VG. Median PFS was 6.3 m (95% CI, 5.3–7.3) for VG and 4.1 m (95% CI, 3.3–4.9) for V (p=0.0011). Objective response rate was 37% (CI 95% 29–46) for VG and 25% (CI 95%: 17–33) for V (p= 0.035). CTC grade 3–4 hematologic toxicity was significantly higher with VG vs. V (65% vs. 43% neutropenia, 33% vs. 17% leucopenia, and 11% vs. 2% thrombocytopenia); febrile neutropenia was present in 10.5% of pts on VG and 6% of pts in V (p=ns). Non-hematological toxicity was low and manageable in both arms. Conclusions: VG demonstrated significant efficacy advantages over V in pts with MBC previously treated with AT, with manageable toxicity. This favorable risk-benefit profile supports the use of this combination in this patient population. [Table: see text]

Oral Vinorelbine

1052 Background: Chemotherapy (CT) plus H is the standard first-line treatment for HER2-positive MBC. H plus vinorelbine is an active and well-tolerated regimen in this setting. The all-oral combination of NVBo and X also appears active and well-tolerated in MBC. We report efficacy and safety results from the first 34 patients (pts) included in an international trial evaluating NVBoXH in HER2-positive MBC. Methods: In this multicenter trial, main eligibility criteria included: HER2-positive disease (IHC 3+ or FISH+), documented measurable MBC previously untreated by CT, relapse 6 months after completing neoadjuvant or adjuvant CT, Karnofsky PS = 70, age =18 years. Pts received 3-weekly cycles of NVBo 60 mg/m2 (cycle 1) escalating to 80 mg/m2 (from cycle 2) days 1 and 8; × 1,000 mg/m2 bid (750 if = 65 years) days 1–14; H 4 mg/kg day 1 as a loading dose then 2 mg/kg i.v. weekly starting on day 8. Treatment was continued until progression or unacceptable toxicity. Primary endpoint is overall response rate. Results: Baseline characteristics: median age 54 years (20% = 65); prior (neo)adjuvant CT 21 pts (62%); type of CT: anthracycline 52%, anthracycline + taxane 29%, CMF 14%, taxane 5%; visceral involvement 29 pts (85%), >2 metastatic sites 13 pts (38%). Treatment administered: median 8 cycles, median relative dose intensity: NVBo 77%, X 81%, H 95%; NVBo dose escalation to 80 mg/m2 in 91% of pts. Safety (n=34, G3/4 NCI CTC v2 adverse events): neutropenia 22 pts (65%), diarrhea 4 pts (12%), febrile neutropenia 3 pts (9%), vomiting 3 pts (9%), hand-foot syndrome 3 pts (9%), asthenia 3 pts (9%), infection without neutropenia 2 pts (6%), LVEF decline 2 pts (6%), stomatitis 1 pt (3%), nausea 1 pt (3%), constipation 1 pt (3%). Efficacy (n=31 evaluable pts): objective response rate (RECIST) 71% (95% CI [52–86]), CR 13%, PR 58%, SD 23%, PD 6%, disease control (CR+PR+ SD for =6 months) 84%. Progression-free survival, overall survival and duration of response data are not yet mature. Conclusions: This is the first trial, in pts with HER2-positive MBC, to show high efficacy with first-line NVBoXH therapy. This regimen can be safely administered in this pt population. No significant financial relationships to disclose.

1133 Background: Pazopanib, an oral small molecule inhibitor of VEGFR, PDGFR, and KIT, has demonstrated activity in phase I, with a recommended phase II dose of 800 mg/d (Hurwitz H et al, J Clin Oncol. 2005;23[16 suppl]:3012.1). We evaluated the activity of single agent pazopanib in recurrent or metastatic breast cancer (MBC). Methods: In this 2-stage design, patients with recurrent or MBC received pazopanib 800 mg/d. The primary endpoint was objective response rate (ORR) of 20%. Response in 3 out of 18 patients was required to go to stage 2. Treatment was continued until progression. Results: 21 patients entered stage 1; 67% were ER positive and all were HER-2-negative. Prior lines of chemotherapy were 1 in 76% and 2 in 14%. Of the 19 evaluable patients, 2 patients remain on treatment. 14 (74%) stopped due to progressive disease, 2 (10%) due to adverse events, and 1 (5%) due to patient request. Best response was partial response (PR) in 1 (5%), stable disease (SD) in 11 (58%), and progressive disease in 7 (37%). Clinical benefit rate (CR, PR, or SD for ≥ 6 months) was 26%. Median time to progression (TTP) was 3.7 months (95% C.I. 1.7 months - not reached). 9 out of 18 patients (50%) with measurable target lesions had some decrease in target lesion size. Estimated progression-free survival at 3 months was 55%, and 28% at 6 months. Adverse events were grade 3/4 elevations in AST (14%) and ALT (10%), and grade 3 hypertension and neutropenia (14% each). Other common events were grade 1/2 lymphopenia, neutropenia, diarrhea, fatigue, skin hypopigmentation, hypertension, nausea, vomiting, anorexia, and headache. Conclusions: Pazopanib is well tolerated and demonstrates activity in pretreated breast cancer. While the target ORR of 20% has not been met, rates of SD and TTP are comparable to other active agents in this setting, and therefore pazopanib may be an interesting agent for future studies in breast cancer.

689 Background: InVELOUR trial the addition of aflibercept to FOLFIRI regimen, demonstrated a statistically significant overall survival improvement in mCRC patients (pts) who progressed on or after a prior oxaliplatin based regimen with or without biologic agents. Our goal is to assess in the real-life setting the activity and safety profile of Afli+F in mCRC. Methods: Retrospective data collection (baseline characteristics, progression free survival [PFS], objective response rate [ORR], salvage surgeries, and safety profile) of pts who received Afli+F as a 2nd line treatment on a compassionate use program in Spain. GERCOR prognostic model has been applied to evaluate PFS. These are the final results of the analysis (Cut-off date June 2015). Results: The retrospective study population comprised 71 pts (34 hospitals); 60.6% men and 39.4% women, median age 64 years (19.7% > 70) and 98.6% had ECOG scores = 0-1. 63.4% (n = 45) had ≥ 2 metastatic sites (liver [81.7%], lung [38.0%]) and 67.7% (46/68) patients were K-RAS mutated. 60.6% (n = 43) had received prior bevacizumab (BVZ) treatment, 16.9% (n = 12) had received prior cetuximab and 5.6% (n = 4) panitumumab. Patients received a median of 6 cycles (range: 1-30) of Afli+F. Median PFS with Afli+F was 5.3 months (CI 95%: 3.7-8.6); which was not significantly modified by the presence of K-RAS mutation (HR: 1.1663; 95%CI: 0.6676-2.0373; p = 0.5867), by prior BVZ treatment (HR: 1.2424; 95%CI: 0.7238-2.1327; p = 0.4283) or by anti-EGFRs treatment (HR: 0.5681; 95%CI: 0.3117-1.0356; p = 0.0604). ORR was 19.7% (CI 95%: 11.2-30.9) and 8.5% (n = 6) of salvage surgeries. The most frequent adverse events grade ≥ 3 related with treatment were asthenia (n = 8), neutropenia (n = 7) and diarrhea (n = 6). The characteristic anti-angiogenic events were hypertension (n = 8), proteinuria (n = 1), vascular events (n = 1), and one intestinal perforation resulting in death. GERCOR prognostic model: Median PFS = 8.30 months [1.28-18.71] low risk, 5.29 [4.08-9.93] intermediate risk and 2.56 [1.94-4.57] high risk. Conclusions: In spite of the differences in sample size, in the real-life setting, Afli+F achieve a PFS comparable to VELOUR, regardless of K-RAS status or prior BVZ and anti-EGFR’s treatment, with an appropriate safety profile.

LBA4 Background: Olaparib is an oral PARP inhibitor with anti-tumor activity in HER2-negative mBC with a g BRCAm (NCT00494234). OlympiAD (NCT02000622) was a randomized, open-label, phase III study that assessed efficacy and safety of olaparib vs standard single agent chemotherapy treatment of physician’s choice (TPC) in pts with HER2-negative mBC and a g BRCAm. Methods: Pts aged ≥18 y with HER2-negative mBC (hormone receptor positive or triple negative [TN]) and a g BRCAm, who had received ≤2 chemotherapy lines for mBC, were randomized (2:1) to olaparib tablets (300 mg po bid) or TPC (21-day cycles of either capecitabine [2500 mg/m2 po days 1–14], vinorelbine [30 mg/m2 IV days 1 and 8] or eribulin [1.4 mg/m2IV days 1 and 8]). Treatment was continued until objective disease progression (RECIST v1.1) or unacceptable toxicity. The primary endpoint was progression-free survival (PFS) assessed by blinded independent central review (BICR). Results: 302 pts were randomized (median age 44 y; 50% TN; 71% prior chemotherapy for mBC; 28% prior platinum) of whom 205 received olaparib and 91 received TPC (6 TPC pts were not treated). At 77% data maturity, PFS by BICR was significantly longer in pts treated with olaparib vs TPC (HR 0.58; 95% CI 0.43, 0.80; P=0.0009; 7.0 vs 4.2 months, respectively). Time to second progression (investigator-assessed) was also longer in the olaparib arm (HR 0.57; 95% CI 0.40, 0.83). Objective response rate was 59.9 and 28.8% in olaparib and TPC arms, respectively. Grade ≥3 adverse events (AE) occurred in 36.6 and 50.5% of olaparib and TPC pts, with AEs leading to discontinuation in 4.9 and 7.7% of pts, respectively. Mean change from baseline in global health-related quality of life (HRQoL, EORTC-QLQ-C30) across all timepoints favored olaparib (difference vs TPC 7.5; 95% CI 2.48, 12.44; P=0.0035). Conclusions: Olaparib tablet monotherapy provided a statistically significant and clinically meaningful PFS benefit to HER2-negative mBC pts with a g BRCAm, compared to standard TPC. The safety profile of olaparib was consistent with prior studies. The efficacy benefit was seen beyond the first progression and HRQoL also improved. Clinical trial information: NCT02000622.

TPS1123 Background: Antiangiogenic therapy in combination with chemotherapy is effective in control advanced breast cancer(ABC). Apatinib is an oral, highly potent tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor 2(VEGFR-2). Phase II clinical trials of Apatinib single agent had presented objective response and manageable toxicity in heavily pretreated, metastatic breast cancer. The median progression free survival (PFS) and median overall survival (OS) of single agent in both triple-negative and non-triple-negative breast cancer were 3.3-4.0 months and 10.3-10.6 months, respectively. The overall response rate and disease control rate (DCR) reached 16.7% and 66.7%, respectively. This all-oral phase II study aims to investigate the efficacy and safety of the oral vinorelbine-Apatinib combination in pre-treated metastatic breast cancer(MBC). Methods: This single arm prospective study enrolled patients with HER2(Human epidermal growth factor receptor-2 ) negative advanced breast cancer, pretreated with anthracycline and taxanes, and who failed in the metastatic setting at least one prior chemotherapy regimen. The estimated Enrollment was 40 patients.The primary end point of this study was PFS. Secondary end points included objective response rate (ORR), DCR, OS and safety. Patients were treated with apatinib 500/425mg daily plus oral vinorelbine 60-80 mg/m2 day1,8,15 every 3 weeks/cycle. Starting doses of Apatinib were chosen according to age, weight and patient status. Patients eligible were evaluated by CT or MRI scan at baseline and every 2 cycles (6 weeks) there after until disease progressed. Adverse events (AEs) were assessed and graded in accordance with the Common Terminology Criteria for AEs, version 4.0. Clinical trial information: NCT02768415.

1056 Background: Oral chemotherapy (CT) is attractive for patients (pts) with MBC. The all-oral regimen of NVBo and X is active with good tolerability in MBC. We report efficacy and safety data from an international phase II study of NVBo plus X. Methods: Main eligibility criteria included: measurable HER2-negative, CT-naive MBC, relapse ≥6 months after completing (neo)adjuvant CT, Karnofsky PS ≥70%, age ≥18 years. Study treatment: 3-weekly cycles of NVBo 60 mg/m2 (cycle 1) or 80 mg/m2 (from cycle 2) d1 and d8, plus X 1,000 (750 if ≥ 65 years) mg/m2 twice-daily d1–14. Treatment was continued until progression or unacceptable toxicity. Results: 55 pts were enrolled: median age: 58.5 years (41% ≥65); prior (neo)adjuvant CT in 63%; type of CT: anthracycline 67%, anthracycline + taxane 18%, CMF 15%; visceral involvement in 78%; >2 metastatic sites in 46%. Median 6 cycles; median relative dose intensity: NVBo 88%, X 87%; NVBo dose escalated to 80 mg/m2 in 94% of pts. G3/4 NCI CTC v2 adverse events (n=54): neutropenia 44% of pts, vomiting 9%, febrile neutropenia 7%, stomatitis 7%, asthenia 7%, infection with G3/4 neutropenia 4%, nausea 4%, diarrhea 4%, hand-foot syndrome 4%, thrombosis/embolism 4%. Efficacy (n=48 evaluable pts): objective response rate (RECIST) 44% (95% CI [29–59]), CR 2%, PR 42%, SD 35%, PD 21%, disease control (CR+PR+SD ≥6 months) 56%. Median time to objective response was 2.9 months. Because of short follow-up, progression-free survival, overall survival and duration of response data are not yet available. Conclusion: The all-oral combination of NVBo and X is an effective and well-tolerated first-line therapy for MBC. Based on these results and the high convenience of oral CT, evaluation of this regimen vs i.v. combinations in a randomized trial is ongoing. [Table: see text]

8538 Background: In cell line studies, YM155 showed markedly potent antiproliferative activity against melanoma with 50% growth inhibition (GI50) values ranging from 0.35 nM to 910 nM. In melanoma tumor-bearing mouse xenograft models, YM155 showed significant antitumor activity including regression of tumors, at doses ranging from 1 to 10 mg/kg/day. Methods: Chemotherapy naive patients with unresectable Stage III or IV melanoma were eligible. The primary endpoint was tumor response defined by RECIST criteria. Secondary endpoints included progression-free survival and toxicity. A Simon's two stage minimax design was utilized with the first stage requiring 1 response (N=27) and a total of 2 responses required at the conclusion of stage II (N=29). Patients were considered evaluable if they completed 2 cycles. YM155 was given as a 168-hour (7-day) continuous infusion every three weeks (1 cycle) at a dose of 4.8 mg/m2/day. Results: Enrollment is complete at 34 pts in order to reach 29 evaluable with treatment ongoing. Results are available for the first 26 pts. Median age was 59 y/o, (range 29 - 88) with ECOG PS of 0–1. There is one objective response of intrabdominal lymph nodes based on Investigator assessment at Cycle 2 confirmed at Cycle 4; another patient had a minor response (24% reduction) at Cycle 6 (currently at Cycle 8). Two subjects have shown stable disease after 6 cycles and remain on study. The median number of cycles is 3 (range 1 - 9). Two of 26 pts reported a grade 3 AE considered possibly related to YM155 (chest pain - nos and catheter related thrombosis). Nineteen of 26 pts have discontinued the study (18 PD, 1 withdrew consent). Conclusions: YM155 induced responses in 2 pts and was generally well tolerated. Given this encouraging response as a single agent, studies of YM155 combined with other agents are under consideration. [Table: see text]

e12018 Background: Addition of capecitabine to docetaxel improves survival outcomes compared with single agent docetaxel in metastatic breast cancer (MBC). In this study we analyzed efficacy of maintenance therapy with single agent capecitabine after six cycles of docetaxel/capecitabine chemotherapy in MBC patients. Methods: Patients with metastatic HER2 negative breast cancer were included. Six cycles of docetaxel (75mg/m2 q3wk) / capecitabine (1650mg/m2/day on days 1 to 14) followed by capecitabine (2000 mg/m2/day on days 1 to 14) were administered. Demographic features, progression free (PFS) and overall survival (OS) and response to treatment were recorded. Results: Fifty-four patients were included. Thirty-five patients (65%) were postmenopausal, and 40 (74%) were ER/PR positive. Median age was 53 (range 28 – 70). Number of metastatic sites was one in 23 patients, two in 21, three or more in 10 patients. Most common metastatic sites were bone (67%), lymph nodes (33%), lungs (30%), liver (13%); 13 patients (24%) had bone only disease. Forty-four (81.5%) patients received treatment in first-line, 10 (18.5%) received in second line setting. Median number of cycles applied (including docetaxel/capecitabine combination) was 9 (range 2 – 31, total 576). Median PFS was 9 months (10.4 for hormone receptor positive, 7.3 for negative patients) and median OS was 28 months. Objective response was assessable in 38 patients. Overall response rate (partial + complete response) was 42.6% (95% CI 29.6 – 55.6) with 1 complete response. Toxicities were evaluated in 41 patients; grade 3/4 neutropenia was observed in 10% and grade 3/4 hand-foot syndrome was observed in 24% of patients. Dose reduction was performed in capecitabine in 37%, and in docetaxel in 20% of patients. Conclusions: Maintenance with single agent capecitabine therapy after six cycles of docetaxel/capecitabine chemotherapy is an effective and tolerable treatment option for HER2 negative MBC patients.

4501 Background: AMG 655 is an investigational, fully human agonist monoclonal antibody (IgG1) that binds human death receptor 5 (DR5), activates caspases, and induces apoptosis in sensitive tumor cells. In preclinical PC models, cooperative activity is observed when G is added to AMG 655. We performed a multi-center phase I trial to evaluate AMG 655 + G in metastatic PC pts. The primary endpoint was dose-limiting toxicity (DLT). Secondary endpoints included toxicity, pharmacokinetics, antibody formation, objective response rate, progression-free survival (PFS), 6-month and overall survival. Methods: Eligible pts had previously untreated metastatic PC and ECOG PS 0 or 1. Pts enrolled into sequential cohorts and received AMG 655 3 or 10 mg/kg IV days (D) 1 and 15 and G 1000 mg/m2 IV D 1, 8, and 15 every 28 D. CT scans were obtained Q8 weeks. Results: 13 pts (3 mg/kg cohort = 6; 10 mg/kg cohort = 7) enrolled from 7/07–11/07. Pt characteristics: females 61%; ECOG PS 1 69%; median age 65 (range 35–81); liver metastases 77%. Median number of cycles: 6 (range 2–12). There were no DLT. Nine (69%) pts had grade 3–4 toxicity, the most common were: thrombocytopenia (4 pts), neutropenia (2 pts), and abdominal pain (2 pts). No anti-AMG 655 antibodies were detected. After one 3 or 10 mg/kg dose of AMG 655 after G, the Cmax and AUC of AMG 655 were similar to those in the first- in-human single-agent study (LoRusso JCO 2007; 25: abstract 3534). Preliminary data indicate no effect of AMG 655 on PK of G. Partial response 31% (4 pts, 2 unconfirmed); stable disease 38%. Median PFS: 5.3 months (95% CI, 3.5, 6.2); 6-month survival rate: 76.2% (95% CI: 42.7%-91.7%). Conclusions: AMG 655 + G is well-tolerated and may have activity in metastatic pancreatic cancer. A randomized phase II trial of G ± AMG 655 at 10-mg/kg is currently enrolling. [Table: see text]
