e15047 Background: Everolimus is a mammalian target of rapamycin (mTOR) inhibitor shown to benefit patients with mRCC after failure of initial VEGFr-TKI therapy. In the phase 3 RECORD-1 trial, median progression-free survival was 4.9 months with everolimus and 1.9 months with placebo (hazard ratio, 0.33; P < .001). REACT (RAD001 Expanded Access Clinical Trial in RCC; NCT00655252) was an open-label, expanded access program that provided everolimus before commercial availability to 1367 patients with VEGFr-TKI refractory mRCC in 34 countries. Final results of REACT were recently published (Eur J Cancer. 2012;48:324-332). Methods: The primary objective of REACT was to evaluate the long-term safety of everolimus 10 mg/day as determined by the overall incidence of grades 3 and 4 adverse events (AEs). Best overall tumor response was assessed according to RECIST 1.0. This subanalysis was conducted to assess primary and secondary end points in a subgroup of patients from 11 EGM countries: Turkey, Australia, Russia, Israel, Lebanon, Jordan, Saudi Arabia, South Korea, Singapore, Taiwan, and Thailand. Results: Baseline characteristics of the EGM population (n = 243) were similar to the overall REACT population: median age, 60.0 years; clear cell histology, 95.1%; and progression on/intolerance to previous VEGFr-TKI therapy, 89.7%/16.9%. Median duration (range) of everolimus exposure was 20.4 (0.3-83.7) weeks. Clinical benefit was observed in 60.1%/53.3% of EGM patients/all patients (stable disease, 55.6%/51.6%; partial response, 4.5%/1.7%). Common grade ≥3 AEs in EGM patients/all patients included anemia (19.8%/13.4%), pneumonia (7.4%/4.2%), hyperglycemia (7.0%/5.5%), stomatitis (5.8%/5.4%), and pneumonitis (2.9%/2.7%); 13.2%/16.6% of EGM patients/all patients discontinued because of AEs. Conclusions: In patients from EGM countries, safety findings and tumor responses were consistent with the overall REACT population and with RECORD-1. Everolimus was well tolerated, with no new safety issues identified.

e15064 Background: Some targeted agents have shown variable safety profiles in Asian vs non-Asian patients with mRCC. A retrospective analysis of sunitinib in Korean patients with mRCC found increased incidence and severity of certain adverse events (AEs) compared with previous global trials (Hong et al. Cancer Res Treat. 2009;41:67-72). The open-label, expanded-access program REACT (RAD001 Expanded Access Clinical Trial in RCC; NCT00655252) provided everolimus, a mammalian target of rapamycin (mTOR) inhibitor, before its regulatory approval to 1367 patients with VEGFr-TKI refractory mRCC from 34 countries. Final results of REACT were recently published (Grünwald et al. Eur J Cancer. 2012;48:324-332). This analysis compared study end points in Asian patients with those in the total REACT population. Methods: The primary objective of REACT was to assess the safety of everolimus 10 mg/day, as determined by the overall occurrence of grade 3/4 AEs. Best overall tumor response was evaluated based on RECIST 1.0. Results: Baseline characteristics of Asian patients (n = 109; from South Korea, Taiwan, Thailand, and Singapore) were similar to those of the total study population. Median duration of everolimus exposure was longer in Asian patients than in the total population: 24.1 (range, 2.0-72.7) vs 14.0 (0.1-83.7) weeks. Overall incidence of grade 3/4 AEs was slightly higher in Asian patients than in the total population (70.6% vs 61.6%); common grade 3/4 AEs in Asian patients and the total population, respectively, included anemia (26.6% vs 13.4%), hyperglycemia (11.9% vs 5.5%), pneumonia (10.1% vs 4.2%), stomatitis (6.4% vs 5.4%), thrombocytopenia (3.7% vs 1.0%), and pneumonitis (3.7% vs 2.7%). More patients in the Asian population than in the total population had achieved disease control: partial response, 3.7% vs 1.7%; stable disease, 67.0% vs 51.6%. Conclusions: In this subanalysis of REACT, Asian patients treated with everolimus experienced a greater clinical benefit with a slightly higher incidence of AEs. These results are supportive of the use of everolimus in the Asian population.

7004 Background: Previous data with dasatinib (SPRYCEL®), a short-acting oral multitargeted kinase inhibitor of BCR-ABL and SRC family kinases, have shown the safety and efficacy of the 70 mg BID dose in CP-CML patients. Surprisingly, phase-I data (NEJM 2006;354:2531) demonstrated complete hematologic (CHR) and major cytogenetic responses (MCyR) among CP-CML patients at total daily doses (TDD) of 100 mg and 140 mg in both the BID and QD schedule, despite the achievement of only transient inhibition of BCR-ABL by dasatinib when administered once daily. Methods: Patients with CP-CML resistant or intolerant to imatinib were randomized to one of 4 dasatinib arms: 1) 100 mg QD; 2) 50 mg BID; 3) 140 mg QD; 4) 70 mg BID. In this randomized, prospective, open-label trial, the primary objective compared the CyR rate among the BID and QD arms. Secondary objectives included comparison of the CyR rate between TTDs of 100 and 140 mg and the safety among the 4 arms. Results: 662 patients were randomized from July 2005 to March 2006 and received treatment. Response rates, with a median duration of treatment of 8 months, are shown below. Duration of CyR and progression-free survival were similar across all 4 arms. There was significantly less grade (Gr) 3–4 neutropenia (P=0.035), thrombocytopenia (P=0.001), anemia (P=0.032), and pleural effusions (P=0.028) in the 100-mg QD arm compared to the other 3 arms combined. No differences were seen across the 4 arms in the rates of other adverse events. There were fewer interruptions and reductions and the least number of patients discontinuing treatment for drug-related toxicity in the 100-mg QD arm. Conclusions: Dasatinib 100 mg QD offers the most favorable benefit-risk ratio in CP-CML. This trial provides the first evidence that intermittent kinase inhibition can achieve deep clinical remissions and is associated with an improved safety profile. One-year follow-up on all subjects, molecular response rates, and BCR-ABL mutation data will be presented. [Table: see text] [Table: see text]

7502 Background: SELECT investigated whether the addition of C to standard chemotherapy improved progression-free survival (PFS) in patients (pts) with recurrent or progressive NSCLC after failure of platinum-based therapy. Methods: SELECT was a multicenter, open label, randomized phase III trial. Per investigator choice, pts received either P (500 mg/m2) or D (75 mg/m2) on day 1 and then were randomized within each group to chemotherapy plus C (400/250 mg/m2) (initial/weekly) or chemotherapy alone. Therapy was given for up to six 3-week cycles; pts randomized to C continued weekly monotherapy until disease progression or unacceptable toxicity. The primary objective was PFS for PC vs. P as determined by an Independent Review Committee (IRC). Secondary endpoints included overall survival (OS), objective response rate (ORR) and duration of response (DOR) by IRC, and safety. Preplanned subgroup analyses for epidermal growth factor receptor (EGFR) staining intensity by immunohistochemistry and histology were performed. Results for PC vs. P only are presented. Results: Between Jan 2005 and Feb 2010, 938 total pts were randomized. Baseline demographics were comparable between PC (n=301) and P (n=304): median age 64 years; male 60%; Caucasian 88%; KPS 80-100/60-70 84%/16%; squamous/non-squamous 24%/76%. Median PFS (months) PC: 2.89 and P: 2.76 (hazard ratio [HR] =1.03 [95% confidence interval (CI)=0.87-1.21]; p=0.76). Median OS (months) PC: 6.93 and P: 7.79 (HR=1.01 [95% CI=0.86-1.20]; p=0.86). ORR PC: 6.6% and P: 4.3% (odds ratio =1.59 [95% CI=0.78-3.26]; p=0.20). Median DOR (months) PC: 4.17 and P: 6.93 (HR=1.58 [95% CI=0.74-3.36]; p=0.24). There were no statistical differences in efficacy based on histology or EGFR staining intensity. More drug-related AEs/SAEs were observed in the PC arm, with differences mainly attributable to skin toxicities, GI (diarrhea/stomatitis), and hypomagnesemia. Conclusions: The addition of C to P did not improve efficacy in this pt population. Further biomarker analyses are planned. The safety profiles for C and P were consistent with existing data and no new safety signals were observed.

TPS3117 Background: Mutations of the RAS/RAF/MEK/ERK signaling pathway, especially RAS, BRAF and IGF-I/II receptor genes play a critical role in the development of many different types of cancers, including breast, colorectal, melanoma, NSCLC, and thyroid. Differentiated thyroid cancer (DTC) is the most common endocrine malignancy, but there is currently no approved therapy for advanced radioiodine-resistant disease. In DTC xenograft models, vertical inhibition of this pathway, achieved by targeting the vascular endothelial growth factor receptor (VEGFR) and MEK, has shown greater clinical efficacy than with either agent alone. Pazopanib (P) is a small molecule tyrosine kinase inhibitor that selectively inhibits VEGFR1-3, PDGFR-α, PDGFR-b, c-kit, and FGFR 1-3. Phase II data in advanced DTC from Bible, et al, indicate a 49% response rate with a PFS of 11.7 months in a patients with PD within 6 months. GSK1120212 (G) is a potent, highly selective, allosteric inhibitor of MEK1/2. In a phase I/II study, Infante et al. reported an ORR of 81% in BRAF mutant melanoma patients when G was combined with a RAF inhibitor. Methods: A phase I, open label, dose escalation trial with P+G is currently accruing pts with advanced malignancies. The study is a standard 3+3 design with an expansion cohort of 25 pts with advanced DTC for correlative endpoints and PK studies. Pts will be treated with P at 400 mg QD, 600 mg QD and 800 mg QD, with G held constant at 1 mg QD; G will then be escalated to 1.5 mg QD and 2 mg QD. Eligibility includes advanced solid tumor, good end organ function and performance status, and PD within 6 months in the expansion cohort. The primary objective is to determine the safety and tolerability of the combination and determine the MTD. Secondary objectives include assessing preliminary efficacy as defined by RECIST criteria and PFS, and exploration of PK/PD endpoints. Serial tumor biopsies will be evaluated for changes in signaling through p-ERK. RAS and RAF mutation sites will be sequenced in order to correlate with PD endpoints and disease response. Currently, DL1 has accrued with no DLTs.

304 Background: The mammalian target of rapamycin (mTOR) inhibitor everolimus is the only medication to have shown efficacy in a randomized, controlled, phase III clinical trial (RECORD-1) in pts with mRCC after progression on VEGFR-TKIs. Everolimus more than doubled progression-free survival (PFS) vs. placebo (4.9 vs 1.9 months) and reduced the risk of disease progression by 67%. This analysis evaluated the effect of everolimus on survival in pts who had received 1 vs 2 prior VEGFR-TKIs. Methods: Pts with mRCC who progressed on sunitinib (SU) and/or sorafenib (SOR) were randomized (2:1) to receive everolimus 10 mg/day (n = 277) or placebo (n = 139) plus best supportive care in the double- blind, phase III RECORD-1 study (ClinicalTrials.gov: NCT00410124 ). Results: Before enrollment, the majority of pts received only 1 VEGFR- TKI (317 pts, 74%), with 317 pts receiving either SU or SOR (everolimus = 211; placebo = 106) and 99 pts receiving both SU and SOR (everolimus = 66; placebo = 33). Median PFS was 5.42 mo (95% confidence interval [CI]: 4.30, 5.82) in pts receiving everolimus who had received 1 prior VEGFR-TKI and 1.87 mo (95% CI: 1.84, 2.14) in those receiving placebo (hazard ratio [HR]: 0.31; 95% CI: 0.23, 0.42; p < .001). Median PFS was 3.78 mo (95% CI: 3.25, 5.13) for the everolimus group in pts who received 2 prior VEGFR-TKIs, versus 1.87 mo (95% CI: 1.77, 3.06) for the placebo group (HR: 0.37; 95% CI: 0.22, 0.63; p < 0.001). Conclusions: Pts in all stratified subgroups derived significant clinical benefit from everolimus treatment, including pts previously treated with either 1 or 2 VEGFR-TKIs. However, there was a trend toward a longer PFS in pts treated with 1 prior VEGFR-TKI compared with 2 VEGFR-TKIs. [Table: see text]

188 Background: Abiraterone or enzalutamide are licensed for use post-docetaxel in metastatic castrate resistant prostate cancer (mCRPC). Both target the androgen receptor signalling pathway. There is little information describing their sequential use. Methods: Patients with mCRPC who had failed treatment with docetaxel and abiraterone received enzalutamide as part of an expanded access program. Patients were reviewed four weekly and post-treatment PSA used to determine efficacy. Results: Twenty three patients, median age 76 (range, 65 to 82), performance status of 1 (15/23) or 2 (8/23) with mCRPC (22/23 bone and 4/23 visceral disease) were enrolled. All had received prior docetaxel and abiraterone as well as cabazitaxel (35%), dexamethasone (30%), and stillboestrol (52%). Median biochemical progression free survival (bPFS) was 11.9 weeks. Nine (39%) patients showed sensitivity to enzalutamide, defined as a greater than 50% reduction in PSA. There was a correlation between PSA response to abiraterone and enzalutamide (R=0.45, p=0.03). In 10 out of 23 and 13 out of 23 patients who were sensitive and insensitive to abiraterone, 60% and 23% had a great than 50% reduction in PSA, respectively. There was a trend to improved bPFS in those sensitive to abiraterone (15.7 vs. 11.4 weeks, p=0.40) and in those who showed any PSA response to abiraterone (15.9 vs. 5.3 weeks, p=0.06). Conclusions: Enzalutamide has activity following failure of docetaxel and abiraterone in mCRPC. The effectiveness is more pronounced in those who have responded to abiraterone.
