There are five distinct histological subtypes of RCC, which are classified according to their cell type of origin1,2 clear-cell carcinoma arises in the proximal tubules, accounts for 75–85% of all RCCs and is associated with a mutation in the von Hippel–Lindau (VHL) gene papillary carcinoma (chromophilic carcinoma) arises in the proximal tubules, accounts for 12–14% of all RCCs and is associated with a mutation in the c-MET gene (type I) or fumarate hydratase (FH) gene (type II) chromophobic, oncocytic and collecting duct carcinomas are associated with mutations in the Birt–Hogg–Dubé (BHD) gene these arise in the collecting ducts and are less common.

Source Royal Marsden Hospital NHS Trust, London, UK. Abstract BACKGROUND: Results from clinical trials have established sunitinib as a standard of care for first-line treatment of advanced or metastatic renal-cell carcinoma (RCC); however, many patients, particularly those with a poorer prognosis, do not meet inclusion criteria and little is known about the activity of sunitinib in these subgroups. The primary objective of this trial was to provide sunitinib on a compassionate-use basis to trial-ineligible patients with RCC from countries where regulatory approval had not been granted. METHODS: Previously treated and treatment-naive patients at least 18 years of age with metastatic RCC were eligible. All patients received open-label sunitinib 50 mg orally once daily on schedule 4-2 (4 weeks on treatment, 2 weeks off). Safety was assessed regularly, tumour measurements done per local practice, and survival data collected where possible. Analyses were done in the modified intention-to-treat (ITT) population, which consisted of all patients who received at least one dose of sunitinib. This study is registered with ClinicalTrials.gov, NCT FINDINGS: As of December, 2007, 4564 patients were enrolled in 52 countries patients were included in the modified ITT population. This population included 321 (7%) patients with brain metastases, 582 (13%) with Eastern Cooperative Oncology Group (ECOG) performance status of 2 or higher, 588 (13%) non-clear-cell RCC, and 1418 (32%) aged 65 years or more. Patients received a median of five treatment cycles (range 1-25). Reasons for discontinuation included lack of efficacy (n=1168 [27%]) and adverse events (n=362 [8%]). The most common treatment-related adverse events were diarrhoea (n=1936 [44%]) and fatigue (n=1606 [37%]). The most common grade 3-4 adverse events were fatigue (n=344 [8%]) and thrombocytopenia (n=338 [8%]) with incidences of grade 3-4 adverse events similar across subgroups. In 3464 evaluable patients, the objective response rate (ORR) was 17% (n=603), with subgroup ORR as follows: brain metastases (26 of 213 [12%]), ECOG performance status 2 or higher (29 of 319 [9%]), non-clear-cell RCC (48 of 437 [11%]) and age 65 years or more (176 of 1056 [17%]). Median progression-free survival was 10.9 months (95% CI ) and overall survival was 18.4 months ( ). INTERPRETATION: In a broad population of patients with metastatic RCC, the safety profile of sunitinib 50 mg once-daily (initial dose) on schedule 4-2 was manageable and efficacy results were encouraging, particularly in subgroups associated with poor prognosis who are not usually entered into clinical trials.

ASCO 2012 Tivozanib versus sorafenib as initial targeted therapy for patients with advanced renal cell carcinoma: Results from a phase III randomized, open-label, multicenter trial. Investigador Principal: Robert Motzer - MSKCC Background: Tivozanib, a potent, selective, long half-life tyrosine kinase inhibitor targeting all three VEGF receptors, showed activity and tolerability in a Phase II trial (JCO 2011;29[18S]:4550). Methods: Patients (pts) with clear cell advanced renal cell carcinoma (RCC), prior nephrectomy, RECIST-defined measurable disease, and Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 were randomized 1:1 to tivozanib (T) 1.5 mg once daily for 3 weeks (wks) followed by 1 wk rest, or sorafenib (S) 400 mg twice daily continuously in a 4-wk cycle. Pts were treatment naïve or received no more than 1 prior systemic therapy for metastatic disease; pts receiving prior VEGF- or mTOR-targeted therapy were excluded. The primary endpoint was progression-free survival (PFS) per blinded, independent radiological review. 500 pts were to be enrolled to observe 310 events, yielding 90% power to detect medians of 9.7 and 6.7 months (m) with 5% type I error (2-sided). Results: A total of 517 pts were randomized to T (n=260) or S (n=257). Demographics were well balanced between the 2 groups, except ECOG 0 (T: 45% vs S: 54%, p=0.035). Median PFS was 11.9 m for T vs 9.1 m for S (HR=0.797, 95% CI 0.639–0.993; p=0.042). In the treatment-naïve stratum (70% of pts enrolled in each arm), the median PFS was 12.7 m for T vs 9.1 m for S (HR 0.756, 95% CI 0.580–0.985; p=0.037). In all pts, objective response rate (ORR) for T was 33% vs 23% for S (p=0.014). The most common adverse event (AE; all grades/≥grade 3) for T was hypertension (T: 46%/26% vs S: 36%/18%) and for S was hand-foot syndrome (T: 13%/2% vs S: 54%/17%). Other important AEs included diarrhea (T: 22%/2% vs S: 32%/6%), fatigue (T: 18%/5% vs S: 16%/4%), and neutropenia (T: 10%/2% vs S: 9%/2%). Patient-reported outcome data are being analyzed. Overall survival data are not mature. Conclusions: Tivozanib demonstrated significant improvement in PFS and ORR compared with sorafenib as initial targeted treatment for advanced RCC. The safety profile of tivozanib is favorable, and includes a low incidence of fatigue, diarrhea, myelosuppression, and hand-foot syndrome. N= 517.

ASCO 2012 Patient preference between Pazopanib (Paz) and Sunitinib (Sun): Results of a randomized double-blind, placebo-controlled, cross-over study in patients with metastatic renal cell carcinoma (mRCC)—PISCES study, NCT Autor Principal: Bernard Escudier- IGR N= pts completaram o questionário. Conclusão: 70% dos pacts preferiram Pazopanibe 60% dos médicos preferiram Pazopanibe Pazopanibe: < redução de dose (13 vs 20%) < interrupção de tto (6% vs 12%) < Fadiga Background: Increasingly pt reported outcomes are being added to traditional efficacy outcomes to understand the clinical relevance of toxicity differences between therapies. This study investigated if tolerability differences were significant enough to lead a patient to prefer continuing their treatment with Paz or Sun. Methods: Pts with mRCC were randomized 1:1 to receive as first line treatment blinded 800mg Paz for 10 weeks followed by a 2-week washout and then 50mg Sun for 10 weeks (4/2 weeks schedule) or vice versa. Pts were stratified based on ECOG performance status (0 vs 1) and number of metastatic sites (0/1 vs 2+). The primary endpoint, patient preference assessed at 22 weeks, was compared using Prescott’s test (α=0.10). At least 102 of 160 planned pts were required to complete the preference questionnaire to provide 80% power to detect a preference for one drug over another of 50% vs 30% with 20% expressing no preference. Other endpoints included physician preference, safety, QoL, pharmacokinetics and biomarkers. Results: Of 168 randomized pts, 126 completed the preference questionnaire. In the protocol-driven primary analysis (n=114), Paz was preferred by 70% of pts, Sun by 22% and 8% had no preference. After adjusting for a modest sequence effect, the difference in preference was 49% [90% CI 37.0 – 61.5% p <0.001] in favor of Paz. All pre-planned sensitivity analyses conducted were statistically significant in favor of Paz, including one which imputed Sun for all unavailable pt preference data. The most common reasons for Paz preference were better QoL and less fatigue. 60% of physicians preferred Paz vs 21% for Sun vs 19% no preference. Adverse events (AE) were in line with known profiles for both drugs. Pts on Paz had fewer dose reductions (13% vs 20%) and interruptions (6% vs 12%) vs Sun, mostly due to AE. There was less fatigue on Paz as assessed by FACIT-Fatigue; treatment difference of 2.49, p= Investigator assessed response (RECIST 1.1) was 22% with Paz vs 24% with Sun, p=0.87. Conclusions: This innovative trial design clearly demonstrates the better tolerability of Paz compared to Sun. J Clin Oncol 30, 2012 (suppl; abstr CRA4502)
