LBA5007 Background: BEV, a humanized anti-VEGF monoclonal antibody, has shown a progression-free survival (PFS) benefit in 2 frontline phase III trials in patients with EOC, PPC and FTC. The therapeutic impact of BEV in combination with carboplatin (C) and gemcitabine (G) followed by single agent BEV to disease progression (PD) was evaluated in this phase III trial in the platinum-sensitive recurrent setting. Methods: Patients had recurrent, platinum-sensitive EOC, PPC or FTC, 1 prior regimen, no prior BEV, ECOG performance status 0-1, measurable disease. Subjects were randomized to: Arm A: [IV C (AUC 4, Day (D) 1) + G (1,000 mg/m2 D1 and 8) + placebo (PL) D1] q21D x 6 cycles (c) → PL q21D until PD or unacceptable toxicity (tox) Arm B: [CG + BEV (15 mg/kg) D1] q21D x 6 c → BEV q21D until PD or tox primary endpoint was investigator assessed PFS (RECIST). Secondary endpoints included objective response (OR), overall survival (OS), duration of response and safety. The design provided 80% power to detect a 27% reduction in the hazard of progression or death in Arm B vs A, limiting the overall type I error of 5%. Results: OCEANS enrolled 484 patients (242 per arm) from 4/07 - 1/10, median follow up of 24 months. BEV plus CG followed by single agent BEV to PD significantly increased PFS compared to CG alone (HR=0.484, p<0.0001). OR increased by 21% (p<0.0001). OS data is immature with only 29% of patients having had an event. The safety profile was consistent with other BEV trials. Conclusions: Results show a statistically significant and clinically relevant benefit when bevacizumab is added to chemotherapy in patients with recurrent, platinum sensitive EOC, PPC, and FTC. This is the first phase III trial of an antiangiogenic to demonstrate a clinical benefit to these patients. [Table: see text]

Purpose This randomized, multicenter, blinded, placebo-controlled phase III trial tested the efficacy and safety of bevacizumab (BV) with gemcitabine and carboplatin (GC) compared with GC in platinum-sensitive recurrent ovarian, primary peritoneal, or fallopian tube cancer (ROC). Patients and Methods Patients with platinum-sensitive ROC (recurrence ≥ 6 months after front-line platinum-based therapy) and measurable disease were randomly assigned to GC plus either BV or placebo (PL) for six to 10 cycles. BV or PL, respectively, was then continued until disease progression. The primary end point was progression-free survival (PFS) by RECIST; secondary end points were objective response rate, duration of response (DOR), overall survival, and safety. Results Overall, 484 patients were randomly assigned. PFS for the BV arm was superior to that for the PL arm (hazard ratio [HR], 0.484; 95% CI, 0.388 to 0.605; log-rank P < .0001); median PFS was 12.4 v 8.4 months, respectively. The objective response rate (78.5% v 57.4%; P < .0001) and DOR (10.4 v 7.4 months; HR, 0.534; 95% CI, 0.408 to 0.698) were significantly improved with the addition of BV. No new safety concerns were noted. Grade 3 or higher hypertension (17.4% v < 1%) and proteinuria (8.5% v < 1%) occurred more frequently in the BV arm. The rates of neutropenia and febrile neutropenia were similar in both arms. Two patients in the BV arm experienced GI perforation after study treatment discontinuation. Conclusion GC plus BV followed by BV until progression resulted in a statistically significant improvement in PFS compared with GC plus PL in platinum-sensitive ROC.

Phase Iii Trial

9030 Background: Activating mutations of BRAF V600 can be found in 40%-50% of melanomas and are related to poor prognosis. In a phase 3 trial for the treatment of metastatic melanoma (MM) in chemotherapy-naive patients, nab-paclitaxel (nab-P) vs dacarbazine (DTIC) demonstrated a significant improvement in the primary endpoint of progression-free survival (PFS), assessed by independent radiological review (IRR), and a trend toward prolonged overall survival (OS) at the interim survival analysis. The study also explored the effect of BRAF status on the efficacy parameters. Methods: Chemotherapy-naive patients with stage IV melanoma (M1c stage 65%; elevated LDH 28%) and ECOG performance status 0-1 were randomized to nab-P 150 mg/m2 on days 1, 8, and 15 of a 28-day cycle (n = 264) or DTIC 1000 mg/m2 on day 1 of each 21-day cycle (n = 265) independent of BRAF status. Prespecified subgroup analyses of final PFS and interim OS in subgroups by BRAF status (V600E mutant, wild-type, or unknown) were performed. Results: BRAF mutation status was balanced between the treatment arms, with 36% and 38% of patients with known BRAF mutation status in the nab-P and DTIC arms, respectively. Patient characteristics were also balanced within BRAF subgroups. As shown in the Table, advantage in the nab-P arm vs DTIC arm was observed for both PFS and interim OS regardless of BRAFmutation status. Poststudy BRAF inhibitor treatment was also balanced. Conclusions: In this phase III trial, treatment effect was independent of BRAF mutation status, benefiting all patients who received nab-P vs DTIC. Therefore nab-P should be considered in the armamentarium for all chemotherapy-naive patients with MM. Clinical trial information: NCT00864253. [Table: see text]

Purpose Metastatic breast cancer (MBC) remains an incurable illness in the majority of cases, despite major therapeutic advances. This may be related to the ability of breast tumors to induce neoangiogenesis, even in the face of cytotoxic chemotherapy. Sunitinib, an inhibitor of key molecules involved in neoangiogenesis, has an established role in the treatment of metastatic renal cell and other cancers and demonstrated activity in a phase II trial in MBC. We performed a randomized phase III trial comparing sunitinib plus capecitabine (2,000 mg/m2) with single-agent capecitabine (2,500 mg/m2) in patients with heavily pretreated MBC. Patients and Methods Eligibility criteria included MBC, prior therapy with anthracyclines and taxanes, one or two prior chemotherapy regimens for metastatic disease or early relapse after a taxane plus anthracycline adjuvant regimen, and adequate organ function and performance status. The primary end point was progression-free survival, for which the study had 90% power to detect a 50% improvement (from 4 to 6 months). Results A total of 442 patients were randomly assigned. Progression-free survival was not significantly different between the treatment arms, with medians of 5.5 months (95% CI, 4.5 to 6.0) for the sunitinib plus capecitabine arm and 5.9 months (95% CI, 5.4 to 7.6) for the capecitabine monotherapy arm (hazard ratio, 1.22; 95% CI, 0.95 to 1.58; one-sided P = .941). There were no significant differences in response rate or overall survival. Toxicity, except for hand-foot syndrome, was more severe in the combination arm. Conclusion The addition of sunitinib to capecitabine does not improve the clinical outcome of patients with MBC pretreated with anthracyclines and taxanes.

4503 Background: There is no established standard chemotherapy for pts with inoperable ABC. We previously reported an improvement in progression-free survival (PFS) in a randomised phase II trial of 86 pts (ABC-01) using gemcitabine/cisplatin (GemCis) vs. gemcitabine (Gem) (Valle ASCO-GI 2006, abstr. 98). This study was extended into ABC-02, a phase III trial, to recruit a further 314 pts with overall survival (OS) as the primary end-point. Methods: Consenting pts with histologically/cytologically-confirmed ABC, aged ≥18 years, ECOG performance status 0 - 2, and adequate haematological, hepatic and renal function were randomised to receive either Cis (25 mg/m2) followed by Gem (1000 mg/m2 D1, 8 q21d) for 8 cycles, or Gem alone (1000 mg/m2 on D1, 8, 15 q28d) for 6 cycles, stratified by extent of disease, site of primary tumour, ECOG score and centre. The trial had an 80% power to detect an OS hazard ratio of 0.73. Results: From May 2005 to October 2008, 324 pts were randomised to ABC- 02 from 34 UK centres. We report the pre-planned combined analysis of ABC-01 and ABC-02 based on 410 pts (GemCis=206/Gem=204). Patient characteristics: median age 64 yrs (range 23–85); male (47%); metastatic disease (75%), locally advanced (25%); gallbladder (36%), bile duct (59%), ampulla (5%); and ECOG 0–1 (87%), 2 (12%). With a median follow-up of 6.1 months and 263 deaths, the median OS was greater with GemCis than Gem, 11.7 vs. 8.2 months (log rank p=0.002), with hazard ratio 0.68 (95%-CI 0.53, 0.86). The median PFS was greater with GemCis than Gem, 8.5 vs. 6.5 months (log rank p=0.003), with hazard ratio 0.70 (95%-CI 0.56, 0.88).Toxicity was similar between the arms (by week 12, 57% had a grade 3/4 toxicity in each arm), though there was a slight excess of neutropenia using GemCis. Conclusions: This is the largest ever study in ABC and demonstrates a clear survival advantage for GemCis without added clinically significant toxicity, setting a new international standard of care.

7551 Background: Axitinib is a potent and selective second-generation inhibitor of VEGF receptors 1, 2, and 3 that has promising single-agent activity in advanced NSCLC. Efficacy and safety of axitinib (in 2 dosing schedules) combined with pem/ciswere evaluatedfor non-squamous NSCLC. Methods: Patients with confirmed stage IIIB, IV, or recurrent non-squamous NSCLC and ECOG performance status (PS) 0 or 1 were stratified by gender and PS, and randomized 1:1:1 to receive six 21-day cycles of axitinib continuously plus pem/cis (arm I); axitinib on Days 2 through 19 followed by a 3-day interruption plus pem/cis (arm II); or pem/cis alone (arm III). Axitinib was administered at a starting dose of 5 mg BID. Pem/cis (500/75 mg/m2) was infused on Day 1 of each cycle. Primary endpoint was progression-free survival (PFS). Results: Baseline characteristics of patients in arm I (n=55), arm II (n=58), or arm III (n=57) ranged between 59–62 yr median age; 62–65% male; 71–85% White; 73–85% current/ex-smokers; and 43–47% PS 0. There were no significant differences in PFS or overall survival (OS) between axitinib-containing arms I and II compared with pem/cis alone, but objective response rates (ORR) were higher (Table). Most common all causality grade 3 adverse events (AEs) in arm I, II, and III, respectively, were hypertension (20%, 17%, 0%); neutropenia (18%, 10%, 9%); nausea (16%, 5%, 7%); vomiting (13%, 5%, 4%); fatigue (11%,16%,16%); and anemia (7%, 14%, 9%). Grade 4 AEs observed in >1 patient were asthenia and pulmonary embolism (2 patients each in arm II). Conclusions: Axitinib combined with pem/cis was generally well tolerated, but efficacy was not significantly better than pem/cis alone in non-squamous NSCLC. [Table: see text]

531^ Background: Final PRIME results showed that pmab + CT significantly improved progression-free survival (PFS) and objective response rate vs CT alone for first-line wild type (WT) KRAS mCRC. Efficacy and PRO by ST severity from the final descriptive analysis of PRIME are presented. Methods: Patients (pts) had no prior chemotherapy for mCRC, ECOG performance status ≤ 2, and tumor tissue available for biomarker testing. The final analysis occurred 30 months after the last pt was enrolled; the primary endpoint was PFS; secondary endpoints included OS, objective response, and safety. Pts who received treatment and were alive without progression at day 28 were included in the ST analysis. Results: 1183 pts were randomized. 1057 pts with WT or MT KRAS mCRC met the criteria for inclusion in the ST analysis. Maximum grade ST was observed by day 28 in > 50% of pts. Results are shown ( table ). Overall differences in change from baseline of the least square means from a mixed effects model of the EQ-5D Overall Health Rating for pmab + CT (n = 285) minus CT alone (n = 294) and for ST gr 0-1 (n = 53) minus ST gr 2-4 (n = 232) were −1.069 (95% CI: −3.6277 to 1.4896) and 0.8971 (95% CI: ‐4.0224 to 5.8167), respectively. The overall safety profile was broadly comparable across ST groups and treatment arms. Conclusions: Pts with WT KRAS mCRC receiving pmab with ST gr 2-4 had longer PFS and OS vs pts receiving CT alone. PRO were not adversely affected by ST severity. [Table: see text]

3620 Background: The primary and final analyses of PRIME demonstrated that pmab + FOLFOX4 significantly improved progression-free survival (PFS) vs FOLFOX4 alone for first-line treatment of patients (pts) with wild-type (WT) KRAS exon 2 mCRC. Methods: Pts were randomized 1:1 to pmab 6.0 mg/kg every 2 weeks + FOLFOX4 or FOLFOX4 alone and had no prior chemotherapy for mCRC, ECOG performance status ≤ 2, and tumor tissue for biomarker testing. The primary endpoint was PFS by central assessment. Secondary endpoints included OS, objective response rate, and safety. KRAS exon 2 tumor status was determined by a blinded central lab prior to the primary analysis. This exploratory analysis of updated survival (>80% OS events) estimated the treatment effect of pmab + FOLFOX4 compared with FOLFOX4 alone on OS by KRAS exon 2 status. Previous analyses in pts with WT KRAS exon 2 tumor status reported OS with an event rate of 54% of pts in the primary analysis and 68% of pts in the final analysis. Results: 1183 pts were randomized and received treatment: 593 pts in the pmab + FOLFOX4 arm and 590 pts in the FOLFOX4 alone arm. The KRAS exon 2 ascertainment rate was 93%, consistent with the primary analysis. 535/656 pts (82%) with WT KRAS exon 2 mCRC had an OS event at the time of this analysis. Results are shown (Table). Conclusions: In this updated analysis, an improvement in OS was observed in pts with WT KRAS exon 2 mCRC treated with pmab + FOLFOX4 vs FOLFOX4 alone (p = 0.03). Median OS was reduced in pts with mutant (MT) KRAS mCRC (p = 0.16) and is consistent with previous analyses. Updated efficacy and safety results will be presented. KRAS testing is critical to select appropriate pts with mCRC for treatment with pmab. Clinical trial information: NCT00364013. [Table: see text]

Purpose Patients with recurrent ovarian, peritoneal, or fallopian tube cancer have limited therapeutic options. There are no reports of nanoparticle albumin–bound paclitaxel (nab-paclitaxel) in patients with recurrent platinum-sensitive disease. We report efficacy and toxicity with nab-paclitaxel in this group. Patients and Methods Forty-seven patients enrolled (44 assessable patients). Main inclusion criteria were histologically or cytologically confirmed epithelial cancer of the ovary, fallopian tube, or peritoneum (any stage, grade 2 to 3 if stage I) and measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) or elevated CA-125 (> 70 U/mL) in patients without measurable disease. Patients received nab-paclitaxel 260 mg/m2 administered intravenously for 30 minutes on day 1 of a 21-day cycle for six cycles or until disease progression. Results Median age was 65.5 years; 76% of patients had stage IIIC or IV disease, 81% had Eastern Cooperative Oncology Group performance status of 0, and 94% had prior surgery. For assessable patients, the objective response rate (ORR) was 64% (15 complete responses [CR] and 13 partial responses [PR] among 44 assessable patients). In patients evaluated with RECIST only, the ORR was 45% (one CR and four PR of 11 patients). In patients with only elevated CA-125, ORR was 82% (seven CRs and two PRs of 11 patients). In patients meeting both RECIST and CA-125 criteria, the ORR was 64% (seven CRs and seven PRs of 22 patients). Median time to response was 1.3 months (range, 0.5 to 4.8 months). Estimated median progression-free survival was 8.5 months. The most frequent grade 3 to 4 treatment-related toxicities were neutropenia (24%) and neuropathy (9%). Conclusion Nab-paclitaxel is active in this group of patients with recurrent ovarian, peritoneal, or fallopian tube cancer. The ORR was 64%. Toxicities were manageable. Further studies of nab-paclitaxel in combination with platinum are warranted.

6049 Background: Epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) represent important therapeutic targets in SCCHN. Cetuximab (C), an IgG1 monoclonal antibody against EGFR, has single agent activity in SCCHN. Upregulation of VEGF has been associated with C resistance, thus, combined targeting may enhance anti-tumor activity. We designed a phase II trial of bevacizumab (B), an anti-VEGF humanized monoclonal antibody, with C to evaluate this hypothesis. Methods: Eligible patients have recurrent or metastatic SCCHN, measurable disease (RESIST), ECOG performance status (PS) 0–2, and no history of bleeding or thrombosis. Up to 1 regimen (without an EGFR inhibitor) for recurrent or metastatic disease and prior chemoradiotherapy with curative intent are allowed. Treatment consists of weekly cetuximab, 250 mg/m2 (after a loading dose 400 mg/m2) and bevacizumab, 15 mg/kg given intravenously every 21 days, until disease progression. The primary endpoint is the objective response rate. Sample size is 45 eligible patients. Specific biomarkers relating to EGFR and VEGFR signaling will be evaluated in tumor tissues and blood samples. Results: 28 patients enrolled (27 eligible). Median age 60 years (range 33–92); male 19; PS 0 (7 pts), PS 1 (18), PS 2 (2). All had prior RT, and 26 had chemotherapy. A median of 4 cycles were given (range, 1–12). Best response in 25 evaluable patients: 5 (20%) PR (1 was uncomfirmed), 14 (56%) SD, and 6 (24%) PD. Progression-free survival was 2.8 months and median overall survival was 8.1 months. Grade (G) 3 adverse events included: hemorrhage (from a benign neck ulcer), 1; hypertension, 2; infection, 2; rash, 2; dysphagia, 4; hypophosphatemia, 1; and fatigue, 1. G 4 AEs: proteinuria, 1. One pt died of aspiration pneumonia, with possible cardiac ischemia of uncertain relationship to study drugs. Conclusions: Preliminary results show that cetuximab and bevacizumab is an active regimen in SCCHN with rare serious toxicities. In particular, our results establish the safety of this bevacizumab-based regimen in regards to bleeding complications in SCCHN. Study accrual continues and biomarker analysis is planned.

5502 Background: Topotecan was evaluated in a novel combination regimen in comparison to standard therapy in front-line EOC. Methods: Women with newly diagnosed advanced EOC stages IIB-IV, ECOG performance status (PS) 0-1, age < 75, were randomized to either Arm 1: cycles 1 - 4: cisplatin 50 mg/m2 d1 plus topotecan 0.75 mg/m2 d1-5 IV; cycles 5 - 8: paclitaxel 175 mg/m2over 3 hrs d1 followed by carboplatin AUC5 day 1 or Arm 2: paclitaxel plus carboplatin as in Arm 1 for 8 cycles. The primary endpoint was progression free survival (PFS) and secondary endpoints included objective response, overall survival (OS), adverse event (AE) and Quality of Life (QoL). The sample size required 800 pts and 631 events to detect an improvement in PFS from 16 to 20 months (power 80%, 2-sided alpha 0.05). Results with 3.6 years median follow-up (MFU) were reported previously: there was no significant difference in PFS (Hoskins P, JNCI 2010). Final results including OS after MFU of 8.2 years are reported. Results: From 2001 to 2005, 819 pts (409 Arm 1, 410 Arm 2) were randomized. 704 PFS events and 605 deaths have occurred. PFS results are similar to first report: Median (months [mo]): 14.6 (Arm 1) and 16.2 (Arm 2), hazard ratio (HR) 1.03 (95% CI:0.81-1.30; p = 0.83). Median OS is 44.2 mo (Arm 1) and 44.8 mo (Arm 2), HR: 0.92 (95% CI:0.71-1.19; p=0.54). Baseline factors found to be independent predictors of OS in multivariate analysis are: a) pre-randomization surgery (debulking with no macro residual disease (MRD) to no debulking HR: 0.47; 95%CI:0.37-0.58; p < 0.0001; debulking with MRD (<1 cm) to no debulking HR: 0.76; 95%CI:0.61-0.94; p = 0.01), b) Stage (stage II to III or IV HR:0.52; 95%CI:0.36-0.76; p = 0.0007) and c) PS (0 vs 1 HR:0.76; 95%CI:0.63-0.91; p = 0.004). Post-treatment AEs were not significantly different in the two arms. Conclusions: OV16 final results confirm that sequential doublets of topotecan and cisplatin followed by carboplatin and paclitaxel offer no improvement in outcomes compared to carboplatin and paclitaxel. Pretreatment debulking, stage II and PS 0 are predictive of longer OS. Clinical trial information: NCT00028743.
