10010 Background: The mammalian target of rapamycin (mTOR) regulates cell growth and proliferation and is abnormally activated in many sarcomas. Ridaforolimus, an oral mTOR inhibitor, demonstrated clinical activity in previous nonrandomized trials in advanced sarcomas following failure of prior chemotherapy. Methods: An international, multicenter, placebo-controlled, phase 3 trial was conducted to evaluate maintenance therapy with ridaforolimus in patients with metastatic soft-tissue or bone sarcomas who achieved disease control from prior chemotherapy. Patients were randomized (1:1) to receive oral ridaforolimus (40 mg) or placebo once daily for 5 days each week. The primary endpoint was progression-free survival (PFS); secondary endpoints included overall survival (OS) and safety and tolerability. For OS, patients were to be followed at 3-month intervals for at least 24 months and up to 60 months after randomization. Results: 702 of 711 randomized patients received treatment. At the time of the data cutoff for OS (386 deaths), patients in the study population had been followed for at least 15 months. Median OS was 93.3 weeks with ridaforolimus vs 83.4 weeks with placebo (hazard ratio [HR]=0.88; 95% confidence interval [CI]: 0.72, 1.08; P=0.23). Ridaforolimus significantly improved PFS vs placebo (HR=0.72; 95% CI: 0.61, 0.85; P=0.0001; median PFS: 17.7 weeks vs 14.6 weeks); PFS improved across all prespecified baseline characteristics. As expected from the class of mTOR inhibitors, the most common adverse events with ridaforolimus were stomatitis, thrombocytopenia, noninfectious pneumonitis, hypertriglyceridemia, hyperglycemia, infections, and rash. Conclusions: Oral ridaforolimus was generally well-tolerated and significantly improved PFS in metastatic sarcoma patients with benefit from prior chemotherapy, offering an effective treatment alternative to surveillance alone. Results of a long-term OS analysis (prespecified to occur at 67% mortality, 24 months minimum follow-up) in the intent-to-treat population will be available in early 2012.

4580 Background: Despite advances in the treatment of clear cell RCC, there is a paucity of data to guide management of nccRCC due to the heterogeneity and rarity of these tumors. The clinical activity of new combination therapies (including immunotherapy (IO), anti-vascular endothelial growth factor inhibitors (VEGF), and mammalian target of rapamycin (mTOR) inhibitors) in metastatic nccRCC is not known. Methods: In this multicenter retrospective analysis, we explored the efficacy of combination systemic therapies in patients with nccRCC. Baseline and follow-up demographic, clinical, treatment, and radiographic data were collected. The primary endpoint was objective response rate (ORR) assessed by investigator review. Secondary endpoints include progression- free survival (PFS), disease control rate (DCR), median duration of response (DOR), overall survival (OS), and biomarker correlates. Results: Among 66 included patients, median age was 59 yr; 60% were male and 62% white. Histologies included papillary (38%), chromophobe (17%), unclassified (24%), translocation (12%), and other (9 %). Sarcomatoid and/or rhabdoid differentiation was present in 18%, 70% had prior nephrectomy, 86% were IMDC intermediate/poor risk, 29% and 32% had liver and bone metastasis respectively. 67% received combination treatment in the first line. Comparison of outcomes based on treatment regimen is shown in the table. Conclusions: Antitumor activity was observed with novel combinations in nccRCC which warrants further prospective studies. Response rates and survival with combination therapy in this dataset remain inferior to rates seen in clear cell RCC.[Table: see text]

The Impact

110 Background: The GRID study showed that regorafenib improves progression-free survival compared with placebo in patients with advanced GIST after failure of at least imatinib and sunitinib (HR 0.27; 1-sided p<0.0001; Demetri 2013). At the time of the primary analysis, no significant difference in the secondary endpoint of overall survival (OS) was observed (HR 0.77; p=0.199), but this result may have been confounded by the high rate of crossover to regorafenib (85%) of placebo patients at progression. We conducted exploratory analyses of updated OS data to assess the effect of correcting for this protocol-planned crossover. Methods: The data cut-off for this updated OS analysis was 31 January 2014 (2 years after the primary analysis). OS was corrected using two randomization-based methods: rank preserving structural failure time (RPSFT) and iterative parameter estimation (IPE); both methods are considered as best choice among all correction analytics. Hazard ratios and 95% CI were derived using the Cox model. Results: A total of 139 deaths had occurred at the time of data cut-off: 91 events (68.4% of patients) in the regorafenib group and 48 (72.7%) in the placebo group. A total of 22 patients remained on regorafenib treatment (median duration 2.1 years, range 0.9–2.4). The updated hazard ratio for OS favored regorafenib (0.85, 95% CI: 0.60 - 1.21; p=0.18). Median OS was estimated as 17.4 months in both groups, with crossover from placebo. The corrected HRs for OS are less than the uncorrected HR (Table). Conclusions: The updated analysis of OS in the GRID trial is consistent with the primary analysis. An exploratory analysis correcting for the impact of cross-over on OS suggests a survival benefit for regorafenib in GIST. Clinical trial information: NCT01271712. [Table: see text]

194 Background: Currently, there are limited therapeutic options for patients with advanced midgut neuroendocrine tumors progressing on first-line somatostatin analog therapy. Methods: NETTER-1 is the first Phase III multicentric, randomized, controlled trial evaluating 177Lu-DOTA0-Tyr3-Octreotate (Lutathera) in patients with inoperable, progressive, somatostatin receptor positive midgut NETs. 230 patients with Grade 1-2 metastatic midgut NETs were randomized to receive Lutathera 7.4 GBq every 8 weeks (x4 administrations) versus Octreotide LAR 60 mg every 4-weeks. The primary endpoint was PFS per RECIST 1.1 criteria, with objective tumor assessment performed by an independent reading center every 12 weeks. Secondary objectives included objective response rate, overall survival, toxicity, and health-related quality of life. Results: Enrolment was completed in February 2015, with a target of 230 patients randomized (1:1) in 36 European and 15 sites in the United States. At the time of statistical analysis, the number of centrally confirmed disease progressions or deaths was 23 in the Lutathera group and 67 in the Octreotide LAR 60 mg group. The median PFS was not reached for Lutathera and was 8.4 months with 60 mg Octreotide LAR [95% CI: 5.8-11.0 months], p < 0.0001, with a hazard ratio of 0.21 [95% CI: 0.13-0.34]. Within the current evaluable patient dataset for tumor responses (n = 201), the number of CR+PR was 19 (18.8%) in the Lutathera group and 3 (3.0%) in the Octreotide LAR 60 mg group (p < 0.0004). Although the OS data were not mature enough for a definitive analysis, the number of deaths was 13 in the Lutathera group and 22 in the Octreotide LAR 60 mg group (p < 0.019 at interim analysis) which suggests an improvement in overall survival. Conclusions: The Phase III NETTER-1 trial provides evidence for a clinically meaningful and statistically significant increase in PFS and ORR, and also suggests a survival benefit in patients with advanced midgut NETs treated with Lutathera. Clinical trial information: NCT01578239.

Purpose Aberrant mammalian target of rapamycin (mTOR) signaling is common in sarcomas and other malignancies. Drug resistance and toxicities often limit benefits of systemic chemotherapy used to treat metastatic sarcomas. This large randomized placebo-controlled phase III trial evaluated the mTOR inhibitor ridaforolimus to assess maintenance of disease control in advanced sarcomas. Patients and Methods Patients with metastatic soft tissue or bone sarcomas who achieved objective response or stable disease with prior chemotherapy were randomly assigned to receive ridaforolimus 40 mg or placebo once per day for 5 days every week. Primary end point was progression-free survival (PFS); secondary end points included overall survival (OS), best target lesion response, safety, and tolerability. Results A total of 711 patients were enrolled, and 702 received blinded study drug. Ridaforolimus treatment led to a modest, although significant, improvement in PFS per independent review compared with placebo (hazard ratio [HR], 0.72; 95% CI, 0.61 to 0.85; P = .001; median PFS, 17.7 v 14.6 weeks). Ridaforolimus induced a mean 1.3% decrease in target lesion size versus a 10.3% increase with placebo (P < .001). Median OS with ridaforolimus was 90.6 weeks versus 85.3 weeks with placebo (HR, 0.93; 95% CI, 0.78 to 1.12; P = .46). Adverse events (AEs) more common with ridaforolimus included stomatitis, infections, fatigue, thrombocytopenia, noninfectious pneumonitis, hyperglycemia, and rash. Grade ≥ 3 AEs were more common with ridaforolimus than placebo (64.1% v 25.6%). Conclusion Ridaforolimus delayed tumor progression to a small statistically significant degree in patients with metastatic sarcoma who experienced benefit with prior chemotherapy. Toxicities were observed with ridaforolimus, as expected with mTOR inhibition. These data provide a foundation on which to further improve control of sarcomas.

The agents currently approved for use in metastatic renal cell carcinoma (mRCC) can be divided broadly into two categories: (1) vascular endothelial growth factor receptor (VEGFR)-directed therapies or (2) inhibitors of the mammalian target of rapamycin (mTOR). The latter category includes everolimus and temsirolimus, both approved for distinct indications in mRCC. Everolimus gained its approval on the basis of phase III data showing a benefit in progression-free survival relative to placebo in patients previously treated with sunitinib and/or sorafenib. In contrast, temsirolimus was approved on the basis of a phase III trial in treatment-naïve patients with poor-risk mRCC, demonstrating an improvement in overall survival relative to interferon-alfa. While these pivotal trials have created unique positions for everolimus and temsirolimus in current clinical algorithms, the role of mTOR inhibitors in mRCC is being steadily revised and expanded through ongoing trials testing novel sequences and combinations. The clinical development of mTOR inhibitors is outlined herein.

Purpose Anaplastic oligodendrogliomas are more responsive to chemotherapy than high-grade astrocytomas. We investigated, in a multicenter randomized controlled trial, whether adjuvant procarbazine, lomustine, and vincristine (PCV) chemotherapy improves overall survival (OS) in newly diagnosed patients with anaplastic oligodendrogliomas or anaplastic oligoastrocytomas. Patients and Methods The primary end point of the study was OS; secondary end points were progression-free survival (PFS) and toxicity. Patients were randomly assigned to either 59.4 Gy of radiotherapy (RT) in 33 fractions only or to the same RT followed by six cycles of standard PCV chemotherapy (RT/PCV). 1p and 19q deletions were assessed with fluorescent in situ hybridization. Results A total of 368 patients were included. The median follow-up time was 60 months, and 59% of patients have died. In the RT arm, 82% of patients with tumor progression received chemotherapy. In 38% of patients in the RT/PCV arm, adjuvant PCV was discontinued for toxicity. OS time after RT/PCV was 40.3 months compared with 30.6 months after RT only (P = .23). RT/PCV increased PFS time compared with RT only (23 v 13.2 months, respectively; P = .0018). Twenty-five percent of patients were diagnosed with combined 1p/19q loss; 74% of this subgroup was still alive after 60 months. RT/PCV did not improve survival in the subgroup of patients with 1p/19q loss. Conclusion Adjuvant PCV chemotherapy does not prolong OS but does increase PFS in anaplastic oligodendroglioma. Combined loss of 1p/19q identifies a favorable subgroup of oligodendroglial tumors. No genetic subgroup could be identified that benefited with respect to OS from adjuvant PCV.

TPS4140 Background: Survival of HER2+ metastatic GC is prolonged by trastuzumab when administered with CF/X (VanCutsem, ASCO 2009). Lapatinib inhibits both EGFR1 and HER2, is active in HER2+ GC lines, and has shown clinical activity in uncontrolled phase II GC trials. A phase III trial of lapatinib with X + oxaliplatin in HER2+ (FISH) GC is closed to recruitment. Additional unaddressed questions include the efficacy and safety of lapatinib with ECF/X (epirubicin + cisplatin + 5-FU or capecitabine (X), which is a preferred chemotherapy (CT) regimen in GC), and its activity in patients (pts) with discordant FISH or IHC HER2 status or EGFR1+. Methods: This is a phase II, randomized, double- blind, placebo controlled, multicenter trial sponsored by the EORTC. About 480 pts with adenocarcinoma of the stomach or esophagogastric junction not amenable to curative surgery and without prior palliative CT are screened centrally for HER2/EGFR1 by FISH and IHC. Patients are enrolled into one of two strata: 1) HER2 FISH- and IHC 2/3+, or 2) HER2 IHC 0/+ and EGFR1 FISH+ or IHC 2/3+. Pts HER2 FISH+/IHC 2/3+ and pts without HER2/EGFR1 by FISH/IHC will be excluded. 168 pts are anticipated to be randomized to lapatinib 1,250 mg cont. until progression or placebo, administered 6 cycles of ECF or ECX (72/96 in stratum 1/2, respectively).The primary endpoint is progression-free survival (PFS) in stratum 2 and 77 events are needed for 80% power to detect an increase in PFS from 4 to 6.5 months with lapatinib (HR=0.615, one-sided alpha 10%). Secondary endpoints include PFS, toxicity, response rate, overall survival, and correlation of HER2/EGFR1 status with response. Currently, half of all screened patients (19/38) have been randomized. So far, 8/38 (21%) pts were HER2+ according TOGA criteria. By FISH or IHC, 14/38 were EGFR1+, with 4/14 pts double HER2/EGFR+. Enrolment continues in 5 centers with about 4-10 patients per month. A safety cohort analysis will be performed in the first 15 pts receiving lapatinib. Conclusions: This is the first trial to analyze prospectively and separately the role of lapatinib combined with chemotherapy in EGFR1+ GC pts stratified by FISH/ IHC.

711 Background: Modified CapeIRI (irinotecan 200 mg/m2 on day 1, capecitabine 1600 mg/m2 on days 1–14 every 3 weeks) with or without bevacizumab (± BV) has shown non-inferiority of overall survival compared with FOLFIRI ± BV based on the phase III study, AXEPT, as second-line chemotherapy for patients with mCRC. In this exploratory analysis of the AXEPT trial, we evaluated the impact of the prior chemotherapy with two different fluoropyrimidine backbones (fluorouracil and leucovorin vs oral fluoropyrimidine) on the efficacy of CapeIRI and FOLFIRI. Methods: Patients were randomized to receive standard FOLFIRI ± bevacizumab or modified CapeIRI ± bevacizumab after failure to fluoropyrimidine-based chemotherapy in the AXEPT study. Prior fluoropyrimidine backbones were categorized into oral fluoropyrimidine-based (eg, capecitabine or S-1) regimen (oral 5-FU group) and fluorouracil and leucovorin-based regimen (infusional 5-FU group). Assessed endpoints included overall survival, progression-free survival, response rate, and safety. Results: Prior fluoropyrimidine backbone was available for 642 patients among all 650 randomized patients (oral 5-FU group in 291, and infusional 5-FU group in 351). Median overall survival was 17.0 and 16.7 months for FOLFIRI ± BV and CapeIRI ± BV in the prior oral 5-FU group, and 14.9 and 16.7 months for FOLFIRI ± BV and CapeIRI ± BV in the prior infusional 5-FU group. Median progression-free survival was 7.9 and 8.6 months for FOLFIRI ± BV and CapeIRI ± BV in the prior oral 5-FU group, and 6.8 and 8.3 months for FOLFIRI ± BV and CapeIRI ± BV in the prior infusional 5-FU group. Conclusions: There was no significant difference in the efficacy of CapeIRI or FOLFIRI regardless of prior fluoropyrimidine backbones. Therefore, CapeIRI ± BV could also be effective for patients after failure of oral fluoropyrimidine-based chemotherapy (eg, CapeOX ± BV). Clinical trial information: NCT01996306. [Table: see text]

Abstract Abstract 1855 Background: Conflicting data regarding the survival benefit of thalidomide maintenance exist in the literature. Recent phase 3 study MMRC.M10 has demonstrated significant toxicity with thalidomide maintenance in combination with steroids. The role of thalidomide maintenance in prolonging PFS and OS is less clear. We conducted a meta-analysis of phase III randomized control trials (RCT) that evaluated thalidomide as maintenance therapy in transplant-eligible patients. Methods: We conducted an electronic literature search of public databases (MEDLINE, EMBASE, Cochrane library) and manual search of conference proceedings of ASH and ASCO. There were seven phase III RCTs that reported the maintenance therapy of thalidomide and survival in MM (Total Therapy 2, IFM 99-02, ALLG trial, HOVON 50, MRC IX trial, NCIC CTG MY.10). One study (Abdelkefi et al., 2008) was retracted and hence not included in the analysis. A formal meta-analysis was conducted using Comprehensive Meta Analysis software (Version 2.0). The outcome data were pooled and reported as hazard ratio (HR). The primary outcome of interest was progression free survival (PFS) and overall survival (OS). Results: A total of 3194 patients (maintenance arm/control arm- 1479/1715, median age 58 years) were evaluated. The 3 year-OS ( HR 0.80, 95% CI 0.70 to 0.917, P=0.001) and 3 year-PFS (HR 0.62, 95% CI 0.55 to 0.69, P=0.000) were superior with maintenance therapy. ‘Steroid and thalidomide’ maintenance therapy was associated with significant OS and PFS improvement (OS HR 0.65, 95% CI 0.47 to 0.89); PFS (HR 0.54, 95% CI 0.44 to 0.67). Overall toxicities with thalidomide maintenance were peripheral neuropathy (PN) 2.184 (95% CI 1.523–3.133) and thromboembolic events (TEE) 1.632 (95% CI 1.076–2.475). Toxicities were increased with thalidomide and steroid maintenance - PN 28.78 (95% CI 1.676–494.13); TEE 2.896 (95% CI 0.76–11.06). Conclusions: Thalidomide as a single agent or in combination with steroids as maintenance therapy improves progression free survival and overall survival. However, high toxicity with steroid combination was observed. Disclosures: Kaufman: Millenium; Onyx; Novartis; Keryx: Consultancy; Merck, Celgene: Research Funding.

Purpose Whereas whole-brain radiotherapy (WBRT) has been the standard treatment of brain metastases (BMs), stereotactic radiosurgery (SRS) is increasingly preferred to avoid cognitive dysfunction; however, it has not been clearly determined whether treatment with SRS is as effective as that with WBRT or WBRT plus SRS. We thus assessed the noninferiority of salvage SRS to WBRT in patients with BMs. Patients and Methods Patients age 20 to 79 years old with performance status scores of 0 to 2—and 3 if caused only by neurologic deficits—and with four or fewer surgically resected BMs with only one lesion > 3 cm in diameter were eligible. Patients were randomly assigned to WBRT or salvage SRS arms within 21 days of surgery. The primary end point was overall survival. A one-sided α of .05 was used. Results Between January 2006 and May 2014, 137 and 134 patients were enrolled in the WBRT and salvage SRS arms, respectively. Median overall survival was 15.6 months in both arms (hazard ratio, 1.05; 90% CI, 0.83 to 1.33; one-sided P for noninferiority = .027). Median intracranial progression-free survival of patients in the WBRT arm (10.4 months) was longer than that of patients in the salvage SRS arm (4.0 months). The proportions of patients whose Mini-Mental Status Examination and performance status scores that did not worsen at 12 months were similar in both arms; however, 16.4% of patients in the WBRT arm experienced grade 2 to 4 cognitive dysfunction after 91 days postenrollment, whereas only 7.7% of those in the SRS arm did ( P = .048). Conclusion Salvage SRS is noninferior to WBRT and can be established as a standard therapy for patients with four or fewer BMs.
