95% CI and curves were compared with log-rank test. The study had <strong>the</strong> ethical<br />

approval.<br />

Results: 1905 pts were screened and 252 pts (13%) were treated with 3 TTs. The<br />

median age was 60 yrs (range 52–68), 73% were male, 96% underwent nephrectomy<br />

and 38% were metastatic at diagnosis. At 1 st line, <strong>the</strong> Motzer class was good,<br />

intermediate, and poor in 48%, 47% and 5% of pts, respectively. PFS for type and<br />

line of <strong>the</strong>rapy are reported in <strong>the</strong> table below. The TTSF was 36.4 (30.5–42.2) vs.<br />

30.6 (26.5–34.6) mos (p = 0.11), and <strong>the</strong> OS was 52.1 (41.6–62.6) vs. 36.3 (31.2–41.4)<br />

mos (p = 0.01), for TKIàTKIàm-TOR and and TKIàm-TORàTKI, respectively. TTSF<br />

for SU-SO-EV was 36.5 vs. 30.4 mos for SU-EV-SO (p = 0.011). When stratified by<br />

ECOG-PS before 3 rd line or baseline MSKCC, TS maintained its independent<br />

prognostic role (p = 0.002 and p = 0.004, respectively).<br />

Conclusions: Only few patients received 3 lines of TTs. The sequence<br />

sunitinib-sorafenib-everolimus was associated with a better TTSF and OS as<br />

compared to <strong>the</strong> sequence sunitinib-everolimus-sorafenib.<br />

Background: Treatment options for metastatic renal cell carcinoma (mRCC) have<br />

expanded since <strong>the</strong> introduction of targeted <strong>the</strong>rapies. The impact of <strong>the</strong>se new<br />

treatment options on overall survival in a complete national cohort of patients is<br />

unclear.<br />

Objective: To analyze Overall Survival (OS), Progression Free Survival (PFS) and<br />

Time to Treatment Failure (TTF) in a complete national cohort of patients.<br />

Design, setting and participants: All Danish patients with mRCC starting first line<br />

treatment with immuno<strong>the</strong>rapy, TKIs or mTOR-inhibitors between 2006 and 2010<br />

were included. Baseline and outcome data were collected retrospectively. Untreated<br />

patients referred for treatment were also assessed.<br />

Outcome measurements and statistical analysis: OS, PFS and TTF was calculated<br />

using <strong>the</strong> Kaplan-Meier method. Differences between OS and treatment year were<br />

assessed using <strong>the</strong> log rank test. Differences in distributions were tested with <strong>the</strong><br />

Chi-square test.<br />

Results and limitations: Between 2006 and 2010, a total of 1073 patients were<br />

referred. Of <strong>the</strong>se, 759 patients received first line treatment and 314 received no<br />

systemic treatment. The proportion of treated patients increased from 64% in 2006 to<br />

75% in 2010 (p = 0.02). In 2006 22% received targeted <strong>the</strong>rapy and this increased to<br />

75% in 2010 (p < 0.00001). In 2006 21% of first line patients received second line<br />

treatment compared to 41% in 2010 (p = 0.01). From 2006 to 2010 we observed an<br />

improved median OS from 11.5 to 15.7 months (p = 0.03), improved median PFS<br />

from 4.1 to 5.5 months (p = 0.001) and an improved median TTF from 3.1 to 4.9<br />

months (p = 0.006) for first line treatment. The untreated population of 314 patients<br />

had a median OS of 3.1 months from date of metastatic disease with no significant<br />

change from 2006 to 2010.<br />

Conclusions: In a complete national cohort of patients, implementation of targeted<br />

<strong>the</strong>rapy has resulted in improved treatment options and outcome for patients with<br />

mRCC.<br />

Background: Sunitinib had a manageable safety profile and encouraging efficacy in a<br />

global expanded-access mRCC study (ClinicalTrials.gov, NCT00130897; Pfizer)<br />

initiated prior to regulatory approval, in patients (pts) ineligible for o<strong>the</strong>r trials (Gore<br />

et al, 2009). Here we report final results.<br />

Methods: Pts aged ≥18 yrs with treatment-naïve or previously treated mRCC<br />

received oral sunitinib on <strong>the</strong> approved 50 mg/day 4-wk-on/2-wk-off schedule. Safety<br />

was assessed regularly and tumor measurements were done as per local standard<br />

practice using RECIST-defined response. Analyses included all pts who received ≥1<br />

dose of sunitinib.<br />

Results: 4,577 pts were enrolled. From July 2005 to November 2011, 4,543 pts<br />

received treatment, including poor prognosis pts with brain metastases (7%), Eastern<br />

Cooperative Oncology Group performance status (ECOG PS) ≥2 (14%), non-clear<br />

cell RCC (12%) and age ≥65 yrs (33%). Median treatment duration was 7.5 mths<br />

and median follow-up was 13.6 mths. 4,298 pts (95%) discontinued; reasons included<br />

lack of efficacy (37%), death (20%) and adverse events (AEs; 15%). The most<br />

common treatment-related AEs of any grade were diarrhea (47%), fatigue (40%),<br />

nausea (36%), decreased appetite (31%), mucosal inflammation (29%), stomatitis and<br />

vomiting (both 28%), hand–foot syndrome (HFS; 27%), dysgeusia (25%),<br />

hypertension (24%), thrombocytopenia (23%) and as<strong>the</strong>nia (22%). The most<br />

common treatment-related grade 3/4 AEs were fatigue (9%), thrombocytopenia (8%),<br />

HFS and as<strong>the</strong>nia (both 7%), hypertension and neutropenia (both 6%) and diarrhea<br />

(5%). In 4,219 evaluable pts, <strong>the</strong> objective response rate (ORR) was 16% (n = 660)<br />

with subgroup ORR as follows: baseline brain metastases (30/324 [9%]), ECOG PS<br />

≥2 (32/587 [5%]), non-clear cell RCC (42/505 [8%]), and age ≥65 yrs (195/1,386<br />

[14%]). Overall median progression-free survival was 9.4 mths (95% CI: 8.8, 10.0)<br />

and overall survival was 18.7 mths (95% CI: 17.5, 19.5).<br />

Conclusions: Results from this global expanded-access mRCC trial confirm <strong>the</strong><br />

safety and efficacy of sunitinib in >4,500 pts with wide-ranging disease states in a<br />

real-world setting. The sunitinib AE profile in this broad population was manageable<br />

and consistent with prior trial results.<br />
