BACKGROUND: Renal-cell carcinoma is highly vascular, and proliferates primarily
through dysregulation of the vascular endothelial growth factor (VEGF) pathway.
We tested sunitinib and sorafenib, two oral anti-angiogenic agents that are
effective in advanced renal-cell carcinoma, in patients with resected local
disease at high risk for recurrence. METHODS: In this double-blind,
placebo-controlled, randomised, phase 3 trial, we enrolled patients at 226 study
centres in the USA and Canada. Eligible patients had pathological stage
high-grade T1b or greater with completely resected non-metastatic renal-cell
carcinoma and adequate cardiac, renal, and hepatic function. Patients were
stratified by recurrence risk, histology, Eastern Cooperative Oncology Group
(ECOG) performance status, and surgical approach, and computerised double-blind
randomisation was done centrally with permuted blocks. Patients were randomly
assigned (1:1:1) to receive 54 weeks of sunitinib 50 mg per day orally throughout
the first 4 weeks of each 6 week cycle, sorafenib 400 mg twice per day orally
throughout each cycle, or placebo. Placebo could be sunitinib placebo given
continuously for 4 weeks of every 6 week cycle or sorafenib placebo given twice
per day throughout the study. The primary objective was to compare disease-free
survival between each experimental group and placebo in the intention-to-treat
population. All treated patients with at least one follow-up assessment were
included in the safety analysis. This trial is registered with
ClinicalTrials.gov, number NCT00326898. FINDINGS: Between April 24, 2006, and
Sept 1, 2010, 1943 patients from the National Clinical Trials Network were
randomly assigned to sunitinib (n=647), sorafenib (n=649), or placebo (n=647).
Following high rates of toxicity-related discontinuation after 1323 patients had
enrolled (treatment discontinued by 193 [44%] of 438 patients on sunitinib, 199
[45%] of 441 patients on sorafenib), the starting dose of each drug was reduced
and then individually titrated up to the original full doses. On Oct 16, 2014,
because of low conditional power for the primary endpoint, the ECOG-ACRIN Data
Safety Monitoring Committee recommended that blinded follow-up cease and the
results be released. The primary analysis showed no significant differences in
disease-free survival. Median disease-free survival was 5·8 years (IQR 1·6-8·2)
for sunitinib (hazard ratio [HR] 1·02, 97·5% CI 0·85-1·23, p=0·8038), 6·1 years
(IQR 1·7-not estimable [NE]) for sorafenib (HR 0·97, 97·5% CI 0·80-1·17,
p=0·7184), and 6·6 years (IQR 1·5-NE) for placebo. The most common grade 3 or
worse adverse events were hypertension (105 [17%] patients on sunitinib and 102
[16%] patients on sorafenib), hand-foot syndrome (94 [15%] patients on sunitinib
and 208 [33%] patients on sorafenib), rash (15 [2%] patients on sunitinib and 95
[15%] patients on sorafenib), and fatigue 110 [18%] patients on sunitinib
[corrected]. There were five deaths related to treatment or occurring within 30
days of the end of treatment; one patient receiving sorafenib died from
infectious colitis while on treatment and four patients receiving sunitinib died,
with one death due to each of neurological sequelae, sequelae of gastric
perforation, pulmonary embolus, and disease progression. Revised dosing still
resulted in high toxicity. INTERPRETATION: Adjuvant treatment with the VEGF
receptor tyrosine kinase inhibitors sorafenib or sunitinib showed no survival
benefit relative to placebo in a definitive phase 3 study. Furthermore,
substantial treatment discontinuation occurred because of excessive toxicity,
despite dose reductions. These results provide a strong rationale against the use
of these drugs for high-risk kidney cancer in the adjuvant setting and suggest
that the biology of cancer recurrence might be independent of angiogenesis.
