Abstract
BACKGROUND In the international, phase III, randomized, double-blind CORRECT trial, regorafenib significantly prolonged overall survival (OS) versus placebo in patients with metastatic colorectal cancer (mCRC) that had progressed on all standard therapies. This post hoc analysis evaluated the efficacy and safety of regorafenib in Japanese and non-Japanese subpopulations in the CORRECT trial. METHODS Patients were randomized 2 : 1 to regorafenib 160 mg once daily or placebo for weeks 1-3 of each 4-week cycle. The primary endpoint was OS. Outcomes were assessed using descriptive statistics. RESULTS One hundred Japanese and 660 non-Japanese patients were randomized to regorafenib (n = 67 and n = 438) or placebo (n = 33 and n = 222). Regorafenib had a consistent OS benefit in the Japanese and non-Japanese subpopulations, with hazard ratios of 0.81 (95 % confidence interval [CI] 0.43-1.51) and 0.77 (95 % CI 0.62-0.94), respectively. Regorafenib-associated hand-foot skin reaction, hypertension, proteinuria, thrombocytopenia, and lipase elevations occurred more frequently in the Japanese subpopulation than in the non-Japanese subpopulation, but were generally manageable. CONCLUSION Regorafenib appears to have comparable efficacy in Japanese and non-Japanese subpopulations, with a manageable adverse-event profile, suggesting that this agent could potentially become a standard of care in patients with mCRC.

Abstract
767 Background: The CORRECT trial (NCT01103323) showed that REG improves overall survival (OS) vs placebo (PBO) in patients with mCRC who failed approved therapies (OS HR 0.77; 1-sided p=0.0052; Grothey 2013). A total of 760 patients were randomized to REG (n=505) or PBO (n=255) in more than 100 centers across North America, Europe, Asia, and Australia. We conducted a post-hoc exploratory subgroup analysis of the 83 (11%) patients from 18 US centers. Methods: Eligible patients had an ECOG PS ≤1 and had received approved therapies, including a fluoropyrimidine, oxaliplatin, irinotecan, and bevacizumab, and if KRAS wild-type cetuximab and/or panitumumab. Data from the overall cohort, including US patients, are provided for perspective. Descriptive statistics are shown. Results: Of the 83 US patients, 36 (43%) were randomized to PBO and 47 (57%) to REG. Baseline characteristics of the US group were consistent with the overall cohort: median age in the US was 58 yr (range, 34 – 85) vs 61 (22 – 85) overall, 49% of US patients were ECOG PS1 (vs 46%), and 46% received ≤ 3 treatments for mCRC (vs 52%). KRAS status mutant/wild-type was 57%/34% in the US vs 57%/39% overall. All patients in the trial had prior bevacizumab and 57% of US patients also had prior cetuximab and/or panitumumab (vs 51% overall). However, higher proportion of patients in the US were Black (11% vs 2%), KRAS status unknown (10% vs 4%), and had colon as the primary disease site (82% vs 65%). Mean percentages of planned REG dose were similar (76% US vs 79% overall) and mean REG treatment duration was 3.1 mos in US vs 2.8 mos overall. Rates of dose modifications REG/PBO were 87%/47% in the US vs 76%/38% overall and grade ≥3 adverse events REG/PBO were 74%/64% vs 78%/49%, respectively. Based on 44 total death events, the HR for OS in the US subgroup was 0.46 (95%CI 0.25 – 0.84) favoring REG; median OS was 4.7 mos for PBO, but could not be estimated for REG due to censored data. However, this analysis was based on a relatively small sample size and event count. Conclusions: Patients treated in the CORRECT study in the US appear similar to the overall cohort and results are generally consistent with the overall findings of the trial. Clinical trial information: NCT01103323.

Abstract
3514 Background: In the CORRECT phase III trial, the multikinase inhibitor regorafenib (REG) demonstrated significant improvement in overall survival (OS) and progression-free survival (PFS) vs placebo (Pla) in patients with metastatic colorectal cancer (mCRC) whose disease had progressed on other standard therapies. An exploratory biomarker subanalysis was conducted to identify protein biomarkers with potential predictive or prognostic value. Methods: Fifteen proteins of interest, many of which are involved in angiogenesis, were quantified by multiplex immunoassay or ELISA in baseline plasma samples collected at study entry from 80% (611/760) of patients. Potential predictive and prognostic effects were evaluated. Results: The biomarker subpopulation was representative of the overall study population in terms of OS and PFS. Using OS as the clinical endpoint, Tie-1 was the only protein whose level demonstrated significant correlation with efficacy (low protein group: REG/Pla, HR 0.87; high protein group, HR 0.56; interaction, p=0.035). Using PFS as the clinical endpoint, von Willebrand factor (VWF) was the only protein whose level demonstrated significant correlation with efficacy (low protein group: REG/Pla, HR 0.39; high protein group, HR 0.60; interaction, p=0.02). Following correction for multiple testing, neither Tie-1 nor VWF data retained statistical significance. Baseline levels of IL-8 and placental growth factor (PlGF) were found to have prognostic value for OS (IL-8: high/low protein levels, HR 3.48, p<0.001; PIGF: HR 1.81, p=0.002). IL-8 was also prognostic for PFS (high/low protein levels: HR 1.63, p<0.001). Conclusions: None of the plasma proteins examined showed significant predictive value for REG efficacy after multiple testing correction. The association between baseline levels of Tie-1/VWF and REG efficacy may be a hypothesis to be tested in further trials. Clinical trial information: NCT01103323.

Abstract
3637 Background: In the CORRECT phase III trial, the multikinase inhibitor REG demonstrated significant improvement in overall survival and progression-free survival vs placebo (P) in patients with mCRC whose disease had progressed on other standard therapies. The most frequent grade 3 AEs were hand–foot skin reaction (HFSR), fatigue, diarrhea, hypertension, and rash. We examined when these AEs first occurred and what impact they had on REG dosing. Methods: Adults with mCRC progressing after all standard therapies were randomized to receive REG 160 mg (n=505) or P (n=255) orally once daily for the first 3 weeks of each 4-week cycle. AEs were managed with dose modifications (reduction and interruption) according to the protocol. Results: The safety population comprised 753 pts (REG n=500, P n=253). The mean ± SD treatment duration was 12.1 ± 9.7 weeks for REG and 7.8 ± 5.2 weeks for P. Treatment-emergent AEs occurred in 99.6% of REG pts and 96.8% of P pts. AEs occurring in ≥10% more REG than P pts were fatigue, HFSR, anorexia, diarrhea, weight loss, voice changes, hypertension, rash/desquamation, oral mucositis, fever, hyperbilirubinemia, and low platelet count. The incidence of grade ≥3 HFSR, fatigue, hypertension, and rash/desquamation typically peaked in cycle 1 and tapered to a relatively stable lower incidence over later cycles, while the incidence of diarrhea remained relatively constant throughout the study; median time to first occurrence and worst grade of these AEs is shown in the table. AEs led to dose modifications in 66.6% of REG pts and 22.5% of P pts. Conclusions: The most common AEs in the REG group typically occurred early during treatment. Close early monitoring of AEs and proper management by dose modification is recommended. Clinical trial information: NCT01103323. [Table: see text]

Abstract
3636 Background: In the CORRECT phase III trial, the multikinase inhibitor REG demonstrated significant improvement in overall survival (OS) and progression-free survival vs placebo (Pla) in patients (pts) with mCRC whose disease progressed on other standard therapies. The most frequent REG-related grade ≥3 adverse events (AEs) of interest were hand–foot skin reaction (HFSR), fatigue, diarrhea, hypertension, and rash/desquamation. We explored whether the impact of REG in pts aged ≥65 years differed from that in younger patients. Methods: Pts with mCRC progressing following all other available therapies were randomized 2:1 to receive REG 160 mg once daily (n=505) or Pla (n=255) for the first 3 weeks of each 4-week cycle. The dose could be modified to manage AEs. The primary endpoint was OS. We report efficacy, safety, and dosing data from REG recipients by age. Results: The REG treatment group included 309 pts <65 years (307 evaluable for safety) and 196 pts ≥65 years (193 evaluable for safety). The OS hazard ratio (REG/Pla) was 0.72 (95% confidence interval [CI] 0.56–0.91) in pts <65 years and 0.86 (95% CI 0.61–1.19) in pts ≥65 years (interaction p-value = 0.405). Median OS was 6.7 vs 5 months for REG vs Pla in pts <65 years, and 6.0 vs 5.6 months, respectively, in pts ≥65 years. Most pts experienced drug-related AEs (<65 years: 93.8%; ≥65 years: 91.7%). The rates of grade ≥3 REG-related AEs of interest and dose modifications are shown in the Table. In pts <65 years vs ≥65 years, median (interquartile range [IQR]) duration of REG was 7.6 weeks (6.6–15.4) vs 7.1 weeks (5.1–17.2), median (IQR) daily REG dose was 160.0 mg (134.6–160.0) vs 160.0 mg (137.5–160.0), and median (IQR) proportion of planned REG dose was 83.3% (65.7–100.0) vs 78.6% (66.7–100.0), respectively. Conclusions: In the CORRECT trial, REG demonstrated an OS benefit in pts <65 years and ≥65 years. Safety and tolerability of REG appeared to be similar in both age subgroups.

Abstract
381 Background: In the CORRECT Ph3 trial, regorafenib demonstrated significant improvement in OS and PFS vs. placebo in subjects with metastatic colorectal cancer (mCRC) who had progressed on standard therapies. An exploratory biomarker substudy was conducted on samples collected from subjects enrolled in CORRECT. Methods: DNA was isolated from archival tumor tissue and fresh baseline plasma samples that were available from 239 (31%) and 503 (66%) subjects enrolled in CORRECT, respectively. Mutations in KRAS, PIK3CA and BRAF were evaluated via BEAMing technology. Results: Mutations were readily detected in DNA isolated from both tumor and plasma samples: KRAS: 59/69%; PIK3CA: 12/17% and BRAF: 1.5/3.4%. The frequency of KRAS mutation detected in tumor samples via BEAMing (59%) was identical to the frequency determined from pre-existing “historical” KRAS mutation data that was available from 96% of the subjects enrolled in the study. Concordance among the mutations detected via BEAMing in tumor vs. plasma was 76% (KRAS), 88% (PIK3CA), and 97% (BRAF). A subset of CRC which was found to be KRAS-wildtype in DNA from archival tumor, but KRAS-mutant in DNA from fresh plasma was identified and may represent subjects whose KRAS mutational status had changed during prior therapy. Correlative subgroup analyses demonstrated that regorafenib mediated a trend for clinical benefit vs. placebo in both KRAS wildtype and mutant subgroups identified by plasma BEAMing (OS: KRAS WT, HR: 0.67, 95% CI: 0.41–1.08; KRAS mutant, HR: 0.81, 95% CI: 0.61–1.09; interaction p=0.561). Similar results were noted for PIK3CA WT/mutant subgroups (OS: WT, HR: 0.75, 95% CI: 0.57–0.99; mutant, HR: 0.84, 95% CI: 0.47–1.50; interaction p=0.723). BRAF was not analysed due to the small number of BRAF-mutant samples. Conclusions: The mutational analysis of DNA isolated from fresh plasma is feasible and robust using the BEAMing platform and may better represent the mutational status of the tumor(s) that a mCRC patient harbors at the time of enrollment than does the mutational analysis of archival primary tumor tissue. Regorafenib was associated with clinical benefit (vs. placebo) in all mutational subgroups evaluated. Clinical trial information: NCT01103323.

Abstract
467 Background: Regorafenib (REG) is an oral multikinase inhibitor that has recently demonstrated significant overall survival benefit vs placebo in the randomized phase III CORRECT study. We examined the time course of adverse events (AEs) in the CORRECT study. Methods: Regorafenib (REG) is an oral multikinase inhibitor that has recently demonstrated significant overall survival benefit vs placebo in the randomized phase III CORRECT study. We examined the time course of adverse events (AEs) in the CORRECT study. Results: The safety population comprised 753 patients (pts): REG n=500; placebo n=253. The mean treatment duration was 12.1 ± 9.7 weeks in the REG group and 7.8 ± 5.2 weeks in the placebo group. Treatment-emergent AEs occurred at any grade in 99.6% of REG pts and 96.8% of placebo pts, at grade 1/2 in 21.6% and 47.8%, respectively, at grade 3 in 56.0% and 26.5%, respectively, and at grade 4/5 in 22.0% and 22.5%, respectively. AEs occurring in ≥10% more REG than placebo pts were fatigue, hand–foot skin reaction (HFSR), anorexia, diarrhea, weight loss, voice changes, hypertension, rash/desquamation, oral mucositis, fever, hyperbilirubinemia, low platelet count. The most frequent AEs deemed to be regorafenib related were HFSR, fatigue, diarrhea, hypertension, and rash/desquamation. The frequency of these AEs over time is shown in the Table. The incidence of HFSR, fatigue, hypertension, and rash/desquamation peaked in cycle 1 and tapered to a relatively stable lower incidence over later cycles. The incidence of diarrhea remained relatively constant throughout treatment. AEs led to dose modification in 66.6% of pts in the REG group and 22.5% in the placebo group. Data on dose intensity across treatment cycles will be presented. Conclusions: In the CORRECT trial, the incidences of the most common AEs in the REG group peaked early during treatment. There appeared to be no evidence for cumulative toxicity of REG. Clinical trial information: NCT01103323. [Table: see text]

Abstract
BACKGROUND No treatment options are available for patients with metastatic colorectal cancer that progresses after all approved standard therapies, but many patients maintain a good performance status and could be candidates for further therapy. An international phase 3 trial was done to assess the multikinase inhibitor regorafenib in these patients. METHODS We did this trial at 114 centres in 16 countries. Patients with documented metastatic colorectal cancer and progression during or within 3 months after the last standard therapy were randomised (in a 2:1 ratio; by computer-generated randomisation list and interactive voice response system; preallocated block design (block size six); stratified by previous treatment with VEGF-targeting drugs, time from diagnosis of metastatic disease, and geographical region) to receive best supportive care plus oral regorafenib 160 mg or placebo once daily, for the first 3 weeks of each 4 week cycle. The primary endpoint was overall survival. The study sponsor, participants, and investigators were masked to treatment assignment. Efficacy analyses were by intention to treat. This trial is registered at ClinicalTrials.gov, number NCT01103323. FINDINGS Between April 30, 2010, and March 22, 2011, 1052 patients were screened, 760 patients were randomised to receive regorafenib (n=505) or placebo (n=255), and 753 patients initiated treatment (regorafenib n=500; placebo n=253; population for safety analyses). The primary endpoint of overall survival was met at a preplanned interim analysis; data cutoff was on July 21, 2011. Median overall survival was 6·4 months in the regorafenib group versus 5·0 months in the placebo group (hazard ratio 0·77; 95% CI 0·64-0·94; one-sided p=0·0052). Treatment-related adverse events occurred in 465 (93%) patients assigned regorafenib and in 154 (61%) of those assigned placebo. The most common adverse events of grade three or higher related to regorafenib were hand-foot skin reaction (83 patients, 17%), fatigue (48, 10%), diarrhoea (36, 7%), hypertension (36, 7%), and rash or desquamation (29, 6%). INTERPRETATION Regorafenib is the first small-molecule multikinase inhibitor with survival benefits in metastatic colorectal cancer which has progressed after all standard therapies. The present study provides evidence for a continuing role of targeted treatment after disease progression, with regorafenib offering a potential new line of therapy in this treatment-refractory population.

Abstract
AIMS Global Investigation of therapeutic DEcisions in hepatocellular carcinoma and Of its treatment with sorafeNib (GIDEON), a global, non-interventional, surveillance study, aims to evaluate the safety of sorafenib in all patients with unresectable hepatocellular carcinoma (uHCC) under real-life practice conditions, particularly Child-Pugh B patients, who were not well represented in clinical trials. METHODS Treatment decisions are determined by each physician according to local prescribing guidelines and clinical practice. Patients with uHCC who are candidates for systemic therapy, and for whom a decision has been made to treat with sorafenib, are eligible for inclusion. Demographic data and medical and disease history are recorded at entry. Sorafenib dosing and adverse events (AEs) are collected throughout the study. RESULTS From January 2009 to April 2011, >3000 patients from 39 countries were enrolled. The prespecified first interim analysis was conducted when the initial approximately 500 treated patients had been followed up for ≥4 months; 479 were valid for safety evaluation. Preplanned subgroup analyses indicate differences in patient characteristics, disease aetiology and previous treatments by region. Variation in sorafenib dosing by specialty are also observed; Child-Pugh status did not appear to influence the starting dose of sorafenib. The type and incidence of AEs was consistent with findings from previous clinical studies. AE profiles were comparable between Child-Pugh subgroups. DISCUSSION The GIDEON study is generating a large, robust database from a broad population of patients with uHCC. First interim analyses have shown global and regional differences in patient characteristics, disease aetiology and practice patterns. Subsequent planned analyses will allow further evaluation of early trends.

Abstract
3502 Background: Regorafenib (REG) is an oral multi-kinase inhibitor. The CORRECT trial was conducted to evaluate REG in patients (pts) with mCRC who had progressed after all approved standard therapies. Methods: Enrollment criteria included documented mCRC and progression during or ≤3 months after last standard therapy. Pts were randomized 2:1 to receive best supportive care plus either REG (160 mg od po, 3 wks on/1 wk off) or placebo (PL). The primary endpoint was overall survival (OS). Secondary endpoints included progression-free survival (PFS), overall response rate, disease control rate, safety and quality of life (QoL). Efficacy analyses across prespecified subgroups were evaluated using univariate Cox regression. Results: 760 pts were randomized (REG: 505; PL: 255). The OS primary endpoint was met at a preplanned interim analysis. OS and PFS were significantly improved in REG arm compared to PL arm: hazard ratio (HR) for OS 0.77 (95% CI 0.64-0.94, 1-sided p=0.0052), median OS 6.4 vs 5.0 mos; HR for PFS 0.49 (95% CI 0.42-0.58, 1-sided p<0.000001), median PFS 1.9 vs 1.7 mos. Comparable OS and PFS benefits were observed in exploratory subgroup analyses by region, age, time from diagnosis of mCRC to randomization, prior lines of treatment, and KRAS status (shown in table). The most common grade 3+ AEs related to REG were hand-foot skin reaction (16.6%), fatigue (9.6%), hypertension (7.2%), diarrhea (7.2%) and rash/desquamation (5.8%). QoL data will be presented. Conclusions: REG demonstrated statistically significant improvement in OS and PFS over PL, as well as comparable efficacy benefits across pt subgroups analyzed. [Table: see text]

Abstract
317 Background: Locoregional treatments (LRTs) are widely used for HCC, with recognized regional variations but no universal standard. GIDEON is a global, prospective, non-interventional study evaluating sorafenib use in HCC patients (pts). The study allows evaluation of global trends in LRTs. Methods: >3000 pts were enrolled in 39 countries (January 2009 to April 2011). Per protocol, the 2nd interim analysis was planned when ~1500 treated pts were followed for ≥4 months. Results: In the safety population analyzed (N=1571), 55% and 46% of pts received prior LRT and transarterial chemoembolization (TACE), respectively. Prior LRTs, including TACE, were more frequent in Asia-Pacific (AP) and Japan than in other regions. In pts who received TACE prior to the initiation of sorafenib therapy, the number of TACE treatments ≥3 was higher in AP and Japan than in other regions. Overall, 76% of pts received conventional TACE, and the most common TACE agent was doxorubicin. Median time from last TACE to initiation of sorafenib therapy was 3.1 months (Table). Worldwide, 8% of pts received TACE, concomitantly with sorafenib. The incidence of sorafenib-related adverse events/serious adverse events was generally similar in pts who did (70%/4%) or did not (64%/9%) receive concomitant TACE. Conclusions: The GIDEON study provides unique insight into the utilization of LRTs worldwide and contributes to better understanding and management of HCC pts. [Table: see text]

Abstract
LBA385 Background: Regorafenib (BAY 73-4506) is an oral multikinase inhibitor of a broad range of angiogenic, oncogenic, and stromal kinases. The phase III CORRECT trial was conducted to evaluate efficacy and safety of regorafenib in pts with mCRC who had progressed after all approved standard therapies. Methods: Enrollment criteria included documented mCRC and progression during or ≤3 months after last standard therapy. Pts were randomized 2:1 to receive regorafenib (160 mg od po, 3 weeks on/1 week off) plus BSC, or placebo (PL) plus BSC. Pts continued on treatment until progression, death, or unacceptable toxicity. The primary endpoint was overall survival (OS). Secondary endpoints included progression-free survival (PFS), overall response rate (ORR), disease control rate (DCR), safety, and quality of life. Results: From May 2010 to March 2011, 760 pts were randomized (regorafenib: 505; PL: 255). Baseline characteristics were balanced between two arms. Preliminary results are available from a pre-planned formal interim analysis. The estimated hazard ratio (HR) for OS was 0.773 (95% CI: 0.635, 0.941; 1-sided p=0.0051). Median OS was 6.4 mos (95% CI: 5.9, 7.3) for regorafenib and 5.0 mos (95% CI: 4.4, 5.8) for PL. The estimated HR for PFS was 0.493 (95% CI: 0.418, 0.581; 1-sided p < 0.000001). Median PFS was 1.9 mos (95% CI: 1.88, 2.17) for regorafenib and 1.7 mos (95% CI: 1.68, 1.74) for PL. ORR was 1.6% for regorafenib and 0.4% for PL. DCR was 44% for regorafenib and 15% for PL (p < 0.000001). Since the prespecified OS efficacy boundary was crossed (nominal α: 0.0093), the Data Monitoring Committee recommended to unblind the study and pts on PL were allowed to cross over to regorafenib. The most frequent grade 3+ AEs in the regorafenib arm were hand-foot skin reaction (17%), fatigue (15%), diarrhea (8%), hyperbilirubinemia (8%), and hypertension (7%). Updated results will be presented. Conclusions: Statistically significant benefit in OS and PFS was observed for regorafenib over PL in pts with mCRC who have failed all approved standard therapies. No new or unexpected safety signal was found.

Abstract
286 Background: GIDEON is an ongoing, global, prospective, non-interventional study of patients (pts) with uHCC receiving sorafenib (Sor) in real-life practice. Differences in pt management across physician specialties can be explored. Methods: The 2nd interim analysis was pre-planned when ~1500 treated pts were followed for ≥4 months. The predefined descriptive subgroup analysis by specialty is presented. Results: Median days between visits varied across specialties: medical oncologists (Med Oncs) had the shortest. Sor dosing was broadly similar across specialties, with hepatologists/gastroenterologists (Hep/GIs) having the greatest incidence of dose reductions. Most commonly reported (>20% of pts) adverse events (AEs; e.g. diarrhea, hand-foot skin reaction [HFSR], fatigue) were similar across specialties, but the incidences varied. These AEs and grade 3/4 AEs were reported by more Hep/GIs and Med Oncs than by surgeons. The incidences of liver-related AEs varied across specialties. Interval-specific AE rates by specialty will be presented. Conclusions: Interim data from GIDEON highlight variations in the assessment and management of uHCC pts across specialties. The reporting of AEs and dose reductions may reflect the frequency of visits with physicians. Findings support the importance of a multidisciplinary team approach to optimize pt care.

Abstract
PURPOSE To characterize the cardiovascular profile of sorafenib, a multitargeted kinase inhibitor, in patients with advanced cancer. METHODS Fifty-three patients with advanced cancer received oral sorafenib 400 mg bid in continuous 28-day cycles in this open-label study. Left ventricular ejection fraction (LVEF) was evaluated using multigated acquisition scanning at baseline and after 2 and 4 cycles of sorafenib. QT/QTc interval on the electrocardiograph (ECG) was measured in triplicate with a Holter 12-lead ECG at baseline and after 1 cycle of sorafenib. Heart rate (HR) and blood pressure (BP) were obtained in duplicate at baseline and after 1 and 4 cycles of sorafenib. Plasma pharmacokinetic data were obtained for sorafenib and its 3 main metabolites after 1 and 4 cycles of sorafenib. RESULTS LVEF (SD) mean change from baseline was -0.8 (±8.6) LVEF(%) after 2 cycles (n = 31) and -1.2 (±7.8) LVEF(%) after 4 cycles of sorafenib (n = 24). The QT/QTc mean changes from baseline observed at maximum sorafenib concentrations (t(max)) after 1 cycle (n = 31) were small (QTcB: 4.2 ms; QTcF: 9.0 ms). Mean changes observed after 1 cycle in BP (n = 31) and HR (n = 30) at maximum sorafenib concentrations (t(max)) were moderate (up to 11.7 mm Hg and -6.6 bpm, respectively). No correlation was found between the AUC and C(max) of sorafenib and its main metabolites and any cardiovascular parameters. CONCLUSIONS The effects of sorafenib on changes in QT/QTc interval on the ECG, LVEF, BP, and HR were modest and unlikely to be of clinical significance in the setting of advanced cancer treatment.

Abstract
PURPOSE This phase III, multicenter, randomized, placebo-controlled trial assessed the efficacy and safety of sorafenib, an oral multikinase inhibitor, in combination with carboplatin and paclitaxel in chemotherapy-naïve patients with unresectable stage IIIB or IV non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Nine hundred twenty-six patients were randomly assigned to receive up to six 21-day cycles of carboplatin area under the curve 6 and paclitaxel 200 mg/m(2) (CP) on day 1, followed by either sorafenib 400 mg twice a day (n = 464, arm A) or placebo (n = 462, arm B) on days 2 to 19. The maintenance phase after CP consisted of sorafenib 400 mg or placebo twice a day. The primary end point was overall survival (OS); secondary end points included progression-free survival and tumor response. RESULTS Overall demographics were balanced between arms; 223 patients (24%) had squamous cell histology. On the basis of a planned interim analysis, median OS was 10.7 months in arm A and 10.6 months in arm B (hazard ratio [HR] = 1.15; 95% CI, 0.94 to 1.41; P = .915). The study was terminated after the interim analysis concluded that the study was highly unlikely to meet its primary end point. A prespecified exploratory analysis revealed that patients with squamous cell histology had greater mortality in arm A than in arm B (HR = 1.85; 95% CI, 1.22 to 2.81). Main grade 3 or 4 sorafenib-related toxicities included rash (8.4%), hand-foot skin reaction (7.8%), and diarrhea (3.5%). CONCLUSION No clinical benefit was observed from adding sorafenib to CP chemotherapy as first-line treatment for NSCLC.

Abstract
Before the development of targeted therapies, administration of cytokines (e.g., interleukin-2, interferon-alpha) was the primary systemic treatment option for advanced renal cell carcinoma. Sorafenib, an oral targeted, multikinase inhibitor, significantly prolonged progression-free survival and overall survival in the Treatment Approaches in Renal Cancer Global Evaluation Trial (TARGET), a large (N = 903) phase III, double-blind, randomised, placebo-controlled study of patients with advanced renal cell carcinoma resistant to standard therapy. This analysis of a patient subgroup from TARGET evaluated the safety and efficacy of sorafenib in patients who had received prior cytokine therapy (sorafenib: n = 374; placebo: n = 368) and in patients who were cytokine-naïve (sorafenib: n = 77; placebo: n = 84). Progression-free survival was significantly prolonged with sorafenib therapy compared with placebo among patients with and without prior cytokine therapy (respectively 5.5 vs. 2.7 months; hazard ratio, 0.54; 95% confidence interval, 0.45-0.64 and 5.8 vs. 2.8 months; hazard ratio, 0.48; 95% confidence interval, 0.32-0.73). Clinical benefit rates for sorafenib-treated patients compared with placebo patients were also higher (cytokine-treated: 83 vs. 54.3%; cytokine-naïve: 85.7 vs. 56.0%). Sorafenib was well tolerated in both subgroups (grade 3/4: 20 and 22%, respectively). Sorafenib demonstrated a consistent, significant clinical benefit against advanced renal cell carcinoma, with a twofold improvement in progression-free survival and disease control rate, with similar toxicities in patients with or without prior cytokine treatment.

Abstract
PURPOSE Sorafenib is an oral multikinase inhibitor that targets the Ras/Raf/MEK/ERK mitogenic signaling pathway and the angiogenic receptor tyrosine kinases, vascular endothelial growth factor receptor 2 and platelet-derived growth factor receptor beta. We evaluated the antitumor response and tolerability of sorafenib in patients with relapsed or refractory, advanced non-small-cell lung cancer (NSCLC), most of whom had received prior platinum-based chemotherapy. PATIENTS AND METHODS This was a phase II, single-arm, multicenter study. Patients with relapsed or refractory advanced NSCLC received sorafenib 400 mg orally twice daily until tumor progression or an unacceptable drug-related toxicity occurred. The primary objective was to measure response rate. RESULTS Of 54 patients enrolled, 52 received sorafenib. The predominant histologies were adenocarcinoma (54%) and squamous cell carcinoma (31%). No complete or partial responses were observed. Stable disease (SD) was achieved in 30 (59%) of the 51 patients who were evaluable for efficacy. Four patients with SD developed tumor cavitation. Median progression-free survival (PFS) was 2.7 months, and median overall survival was 6.7 months. Patients with SD had a median PFS of 5.5 months. Major grades 3 to 4, treatment-related toxicities included hand-foot skin reaction (10%), hypertension (4%), fatigue (2%), and diarrhea (2%). Nine patients died within a 30-day period after discontinuing sorafenib, and one patient experienced pulmonary hemorrhage that was considered drug related. CONCLUSION Continuous treatment with sorafenib 400 mg twice daily was associated with disease stabilization in patients with advanced NSCLC. The broad activity of sorafenib and its acceptable toxicity profile suggest that additional investigation of sorafenib as therapy for patients with NSCLC is warranted.

Abstract
e16099 Background: Results of the phase III TARGET trial, a randomized, double-blind, placebo-controlled study of sorafenib (SOR) treatment in pts with clear-cell RCC in whom 1 prior systemic therapy had failed, indicated that SOR is effective and safe for pts with advanced RCC, leading to the approval of SOR for the treatment of advanced RCC. Diabetes can be associated with increased morbidity during treatment in a variety of malignancies. Therefore, an exploratory subset analysis was performed to evaluate the efficacy and safety of SOR in pts enrolled in TARGET with or without diabetes at baseline. Methods: Pts (N=903) with advanced clear-cell RCC, ECOG PS 0–2, and low- or intermediate-risk MSKCC score were randomized 1:1 to SOR 400 mg BID or placebo (PBO). End points included OS, PFS, and safety. A planned independently-assessed formal analysis of PFS showed significant benefit for SOR over PBO; consequently, pts assigned to PBO were able to cross over to SOR. Results: Pt demographics were similar for all subsets. Pre- crossover data by subset are shown in the table . The incidence of drug-related adverse events (AEs) across subgroups was consistent with that for the overall population. In pts with vs without diabetes, treatment with SOR was not associated with increased hyperglycemia (1 pt/arm in the without diabetes subgroups only) or hypertension. Conclusions: The safety profile of SOR in pts with diabetes was comparable with that for the overall study population. SOR was well tolerated and AEs were manageable. Trends in improved PFS were observed for SOR regardless of baseline diabetes status; however, the small diabetic subset limits interpretation of a SOR OS benefit in this subpopulation. *Final PFS of overall study population based on independent review from Jan 2005; all other data from May 2005 database [Table: see text] [Table: see text]

Abstract
Background The perception that older cancer patients may be at higher risk than younger patients of toxic effects from cancer therapy but may obtain less clinical benefit from it may be based on the underrepresentation of older patients in clinical trials and the known toxic effects of cytotoxic chemotherapy. It is not known how older patients respond to targeted therapy. Methods This retrospective subgroup analysis of data from the phase 3, randomized Treatment Approach in Renal Cancer Global Evaluation Trial examined the safety and efficacy of sorafenib in older (age ≥70 years, n = 115) and younger patients (age <70 years, n = 787) who received treatment for advanced renal cell carcinoma. Patient demographics and progression-free survival were recorded. Best tumor response, clinical benefit rate (defined as complete response plus partial response plus stable disease), time to self-reported health status deterioration, and toxic effects were assessed by descriptive statistics. Health-related quality of life was assessed with a Cox proportional hazards model. Kaplan–Meier analyses were used to summarize time-to-event data. Results Median progression-free survival was similar in sorafenib-treated younger patients (23.9 weeks; hazard ratio [HR] for progression compared with placebo = 0.55, 95% confidence interval [CI] = 0.47 to 0.66) and older patients (26.3 weeks; HR = 0.43, 95% CI = 0.26 to 0.69). Clinical benefit rates among younger and older sorafenib-treated patients were also similar (83.5% and 84.3%, respectively) and were superior to those of younger and older placebo-treated patients (53.8% and 62.2%, respectively). Adverse events were predictable and manageable regardless of age. Sorafenib treatment delayed the time to self-reported health status deterioration among both older patients (121 days with sorafenib vs 85 days with placebo; HR = 0.66, 95% CI = 0.43 to 1.03) and younger patients (90 days with sorafenib vs 52 days with placebo; HR = 0.69, 95% CI = 0.59 to 0.81) and improved quality of life over that time. Conclusions Among patients with advanced renal cell carcinoma receiving sorafenib treatment, outcomes of older (≥70 years) and younger (<70 years) patients were similar.

Abstract
PURPOSE BAY 50-4798 is an analogue of interleukin-2 that selectively activates T cells over natural killer cells. This phase I study was designed to determine the maximum tolerated dose (MTD) and safety of BAY 50-4798, screen for tumor response, and assess pharmacokinetics. EXPERIMENTAL DESIGN Forty-five patients with metastatic melanoma or renal cancer were enrolled, 31 on escalating doses to determine the MTD, with 20 renal cell carcinoma patients treated at MTD to detect antitumor activity. BAY 50-4798 was delivered i.v. every 8 h, days 1 to 5 and 15 to 19, and could be repeated after 9 weeks if tumor was stable or responding. RESULTS The MTD was defined by and reported in terms of doses received. The doses tested ranged from 1.3 to 26.1 microg/kg, and the MTD was defined as 10.4 microg/kg based on toxicities similar to those of aldesleukin. Two patients achieved partial responses, one with melanoma and one with renal cell carcinoma. Among all 45 patients, 53% and 9% experienced a grade 3 and 4 toxicity, respectively. Among the patients treated at the MTD of 10.4 microg/kg, 71% and 10% experienced a grade 3 and 4 toxicity, respectively. Pharmacokinetics showed dose-dependent peak concentrations (C(max)) and area under the curve with a half-life of approximately 2 h and no evidence of accumulation. Lymphocyte subset analysis confirmed the preferential expansion of T-cell subsets over natural killer cells. CONCLUSIONS The antitumor activity of BAY 50-4798 in malignancies that respond to high-dose interleukin-2 was low. BAY 50-4798 might provide advantages over aldesleukin in antigen-specific immunotherapies.

Abstract
7002 Background: Sorafenib, an oral multi-kinase inhibitor, targets the Raf/MEK/ERK pathway at the level of Raf kinase and receptor tyrosine kinases, and has shown efficacy against several tumor types in phase I/II trials. Non-small-cell lung cancer (NSCLC) is associated with mutations in k-ras, upstream of Raf/MEK/ERK. Methods: This multi-center, uncontrolled, phase II trial evaluated efficacy (every 8 weeks using RECIST) and safety of sorafenib (400 mg bid, continuous) in patients with relapsed or refractory advanced NSCLC. Plasma for proteomic biomarker analysis (ELISA [n=44]; mass-spectrometry [n=43]) was taken at screening, Day 21 of Cycle 1, and Day 1 of Cycle 3. Results: Fifty-two of 54 patients enrolled received sorafenib. Most (49/52) patients who received sorafenib had stage IV NSCLC. Thirty patients (59%) out of 51 evaluable for efficacy had SD. Although there were no confirmed PRs, tumor shrinkage was observed in 15 (29%) patients (four had ≥30% shrinkage). Patients with SD had a median progression-free survival (PFS) of 23.7 weeks, while all evaluable patients (n=51) had a median PFS of 11.9 weeks and median overall survival of 29.3 weeks. The most frequent drug-related adverse events observed in 52 patients were diarrhea (21 [40%] patients), hand-foot skin reaction (HFS; 19 [37%]), fatigue (14 [27%]), and nausea (13 [25%]). Frequent drug-related adverse events ≥ grade 3 included HFS (n=5 [10%]) and hypertension (n=2 [4%]). Three patients discontinued due to adverse events (HFS, elevated lipase, and myocardial infarction). There were nine deaths within 30 days of discontinuation of sorafenib (n=5 PD; n=2 cardiopulmonary arrest; n=1 hemoptysis; and n=1 unknown cause). The levels of five proteins measured by ELISA, either at screening or change over treatment duration, correlated significantly with time to progression (TTP) or maximum tumor shrinkage. Levels of five additional proteins, identified by mass-spectrometry, also correlated with TTP. Conclusions: Identified biomarkers may help assess efficacy of sorafenib in NSCLC patients. Sorafenib 400 mg bid is generally well tolerated and shows promising efficacy in patients with advanced, progressive NSCLC, with approximately 60% of pts achieving disease stabilization.

Abstract
BACKGROUND BAY 43--9006, an oral multi-kinase inhibitor, targets serine-threonine kinases and receptor tyrosine kinases, and affects the tumor and vasculature in preclinical models. Based on its pharmacologic effect, it may be a useful cancer treatment. This study determined the maximum tolerated dose (MTD) of BAY 43-9006 in 42 patients with advanced, refractory metastatic or recurrent solid tumors. Dose-limiting toxicities (DLTs), safety, pharmacokinetics and tumor response were also evaluated. PATIENTS AND METHODS In this open-label, phase I, dose-escalation study, BAY 43--9,006 was administered orally in repeated cycles of 35 days (28 days on/7 days off). Eight doses were investigated: from 50 mg every fourth day to 600 mg twice daily. Treatment continued until unacceptable toxicity, tumor progression or death. RESULTS The MTD was 400 mg twice daily. BAY 43-9006 was well tolerated, with mild to moderate toxicities; only six patients discontinued study therapy due to adverse events. DLTs consisted of hand-foot skin reaction in three of seven patients receiving 600 mg twice daily. Stable disease was achieved in 22% of patients; median duration of stable disease was 7.2 months. Consistent with its observed half-life of approximately 27 h, BAY 43-9, 006 accumulated on multiple dosing. Increases in exposure were less than proportional to the increases in dose. CONCLUSIONS Results indicate that further clinical investigation of BAY 43--9006 is warranted, and suggest it could be a promising future therapy for patients with cancer.

Abstract
Sorafenib is a novel, small-molecule anticancer compound that inhibits tumor cell proliferation by targeting Raf in the Raf/MEK/ERK signalling pathway, and inhibits angiogenesis by targeting tyrosine kinases such as vascular-endothelial growth factor receptor (VEGFR-2 and VEGFR-3) and platelet-derived growth factor receptor (PDGFR). In vitro microsomal data indicate that sorafenib is metabolized by two pathways: phase I oxidation mediated by cytochrome P450 (CYP) 3A4; and phase II conjugation mediated by UGT1A9. Approximately 50% of an orally administered dose is recovered as unchanged drug in the feces, due to either biliary excretion or lack of absorption. The aim of this study was to evaluate the effect of CYP3A inhibition by ketoconazole on sorafenib pharmacokinetics. This was an open-label, non-randomized, 2-period, one-way crossover study in sixteen healthy male subjects. A single 50 mg dose of sorafenib was administered alone (period 1) and in combination with ketoconazole 400 mg once daily (period 2) (ketoconazole was given for 7 days, and a single 50 mg sorafenib dose was administered concomitantly on day 4). No clinically relevant change in pharmacokinetics of sorafenib and no clinically relevant adverse events or laboratory abnormalities were observed in this study upon co-administration of the two drugs. Plasma concentrations of the main CYP3A4 generated metabolite, sorafenib N-oxide, decreased considerably upon ketoconazole co-administration. This effect is in accordance with the in vitro finding that CYP3A4 is the primary enzyme for sorafenib N-oxide formation. Further, these data indicate that blocking sorafenib metabolism by the CYP3A4 pathway will not lead to an increase in sorafenib exposure. This is consistent with data from a clinical mass-balance study that showed 15% of the administered dose was eliminated by glucuronidation, compared to less than 5% eliminated as oxidative metabolites. Since there was no increase in sorafenib exposure following concomitant administration of the highly potent CYP3A4 inhibitor ketoconazole with low dose sorafenib, it is postulated that higher therapeutic doses of sorafenib may be safely co-administered with ketoconazole, as well as with other inhibitors of CYP3A.

Abstract
OBJECTIVES To assess the pharmacodynamic effects of coadministered vardenafil and tamsulosin in patients with benign prostatic hyperplasia (BPH) undergoing stable tamsulosin therapy. METHODS In this Phase 1, placebo-controlled, two-stage, two-way, crossover study, 22 patients undergoing stable (longer than 4 weeks) tamsulosin therapy for BPH (18 using 0.4 mg and 4 using 0.8 mg tamsulosin daily) received vardenafil 10 mg (or placebo), followed by vardenafil 20 mg (or placebo), simultaneously with tamsulosin. The mean maximal change from baseline with vardenafil use versus placebo was evaluated for supine and standing blood pressure and heart rate for up to 6 hours after dosing. RESULTS In patients receiving vardenafil 10 mg, the mean maximal change from baseline versus placebo in supine systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate was -4.5 mm Hg (95% confidence interval [CI] -8.2 to -0.8), -2.3 mm Hg (95% CI -4.9 to 0.4), and 3.7 beats per minute (95% CI 1.1 to 6.3), respectively. In patients receiving vardenafil 20 mg, the mean maximal change from baseline versus placebo in supine SBP, DBP, and heart rate was -4.0 mm Hg (95% CI -6.3 to -1.8), -2.9 mm Hg (95% CI -5.6 to -0.2), and 0.8 beats per minute (95% CI -1.2 to 2.9), respectively. These hemodynamic changes were similar to those obtained in the standing position. Two placebo patients and 1 vardenafil 10-mg patient had a drop of 20 mm Hg or more in standing DBP; 1 vardenafil 10-mg patient had a standing SBP drop of 30 mm Hg or more. No patient exhibited symptomatic hypotension (SBP less than 85 mm Hg with dizziness). Three patients receiving vardenafil 20 mg/tamsulosin 0.4 mg reported dizziness, but never had an SBP of less than 95 mm Hg. No serious adverse events were reported. CONCLUSIONS In this study, no evidence was found that coadministered vardenafil and tamsulosin induced clinically significant hypotension in patients with BPH.

Abstract
BACKGROUND In addition to lowering plasma levels of low-density lipoprotein cholesterol (LDL-C), statins also raise high-density lipoprotein cholesterol (HDL-C). HYPOTHESIS Recent studies have shown that treatment with simvastatin results in larger increases in HDL-C than those seen with atorvastatin. The results of three clinical studies are analyzed, comparing the effects of simvastatin and atorvastatin on HDL-C and apolipoprotein A-I (apo A-I) in the total cohort and in several subgroups of hypercholesterolemic patients. The three studies were all multicenter, randomized clinical trials that included simvastatin (20-80 mg) and atorvastatin (10-80 mg) treatment arms. The subgroup analyses performed were gender; age (< 65 and > or = 65 years); baseline HDL-C (male: < 40 or > or = 40 mg/dl; female: < 45 or > or = 45 mg/dl), baseline LDL-C (< 160 or > or = 160 mg/dl), and baseline triglycerides (< 200 or > or = 200 mg/dl). RESULTS Both drugs produced similar increases in HDL-C levels at low doses; however, at higher drug doses (40 and 80 mg), HDL-C showed a significantly greater increase with simvastatin than with atorvastatin (p < 0.05 to < 0.001). Therefore, while HDL-C remained consistently elevated across all doses of simvastatin, there appeared to be a pattern of decreasing HDL-C with an increasing dose of atorvastatin. A similar negative dose response pattern was also observed with apo A-I in atorvastatin-treated patients, suggesting a reduction in the number of circulating HDL particles at higher doses. Both drugs reduced LDL-C and triglycerides in a dose-dependent fashion, with atorvastatin showing slightly greater effects. The differential effects of atorvastatin and simvastatin on HDL-C and apo A-I were observed for both the whole study cohorts and all subgroups examined; thus, no consistent treatment-by-subgroup interactions were observed. CONCLUSION The data presented show that, across different hypercholesterolemic patient subgroups, simvastatin increases HDL-C and apo A-I more than atorvastatin at higher doses, with evidence of a negative dose response effect on HDL-C and apo A-I with atorvastatin, but not simvastatin.
