Pazopanib indication
• Pazopanib is indicated in adults for the first-line treatment of advanced
renal cell carcinoma (RCC) and for patients who have received prior cytokine
therapy for advanced disease1
• Pazopanib’s licence is conditional pending further clinical data from GSK,
including the outcome of the head-to-head study (COMPARZ) of Pazopanib
versus sunitinib.
1. Votrient Summary of Product Characteristics. January 2013
Pazopanib NICE Technology Appraisal Guidance (TA 215)1
• Pazopanib is recommended as a first-line treatment option for people with
advanced renal cell carcinoma
• who have not received prior cytokine therapy and have an Eastern
Cooperative Oncology Group (ECOG) performance status of 0 or 1
and
• under the terms of the agreed Patient Access Scheme which provides
pazopanib with a 12.5% discount on the list price, and a possible future
rebate linked to the outcome of the head-to-head COMPARZ trial
1. NICE. Pazopanib for the first-line treatment of advanced renal cell carcinoma. Final appraisal guidance no. 215. February 2011.
Pazopanib Scottish Medicines Consortium Advice No. 676/111
• Pazopanib is accepted for restricted use within NHS Scotland for the firstline treatment of advanced RCC.
• This SMC advice takes account of the benefits of a Patient Access Scheme
(PAS) that improves the cost-effectiveness of Pazopanib and is contingent
upon the continuing availability of the PAS in NHS Scotland.

Patient preference as a clinical endpoint
• Previous oncology trials have shown a strong association between
toxicity/tolerability and quality of life (QoL), suggesting that patient
preference is a useful endpoint for cross-over studies1,2
• PISCES was designed to understand how the differences in tolerability
between pazopanib and sunitinib translated into a patient preference
• The cross-over design allows patients to be exposed to both drugs in a
comparable health state and then choose which they prefer
• This is the first study of its kind in advanced renal cell carcinoma (RCC)

Patient preference (pazopanib vs. sunitinib)
Patient preference questionnaire
• Collected at the end of treatment period 2
• Prior to unblinding
• Prior to disclosure of final tumour assessment
• By patients who had received ≥ 1 dose in both treatment periods
• Patients selected
• Which drug they preferred or whether they had no preference
• The factors which influenced this preference
• The most important reason for their preference
• Patient preference questionnaire currently unvalidated. Developed in conjunction with
Professor David Cella, USA

PISCES summary
• Significantly more patients preferred pazopanib over sunitinib (70% vs. 22%; p<0.001),
with the remaining 8% of patients expressing no preference for either treatment
• The most important reason for preferring pazopanib was less fatigue or no single reason
• The most important reason for preferring sunitinib was no single reason
• High level of concordance between patient and physician preference, with 61% of
physicians preferring pazopanib over sunitinib (22% preference)
• FACIT-fatigue tool showed that patients experienced statistically significantly less fatigue
on pazopanib than sunitinib (mean scores differed by 2.5 points, p=0.002). However, this
did not achieve the minimally important difference (MID) threshold of >3 points.
• SQLQ showed patients experienced less hand, foot and mouth/throat soreness with
pazopanib than sunitinib. Mean scores favoured pazopanib
PISCES summary
• Notable differences in some AEs between pazopanib and sunitinib include:
• Diarrhoea (more frequent with pazopanib; 42% vs. 32%)
• Stomatitis (more frequent with sunitinib; 16% vs. 5%)
• Mucositis (more frequent with sunitinib; 22% vs. 16%)
• Hand-foot syndrome (more frequent with sunitinib; 26% vs. 16%)
• Asthenia (more frequent with sunitinib; 24% vs. 16%)
• Interestingly, the incidence of fatigue as recorded as an AE was similar between the two
drugs (29% vs. 30%)
• Greater incidence of haematological toxicity with sunitinib
• Pazopanib was associated with fewer dose reductions and discontinuations due to AEs

Contra-indications Hypersensitivity to active substance or excipients. Special Warnings
and Precautions Hepatic effects: Hepatic failure reported during pazopanib use; increases in
serum transaminases (ALT, AST) and bilirubin also observed. Monitor liver function before
initiation of treatment and ≥once every 4 weeks for first 4 months, and periodically thereafter.
If transaminases ≤8xULN, continue pazopanib with weekly monitoring until they return to
≤Grade 1. If transaminases >8xULN, interrupt pazopanib until they return to ≤Grade 1. If
transaminases >3xULN occur following re-introduction, discontinue pazopanib. If
transaminases >3xULN occur concurrently with bilirubin >2xULN, perform bilirubin
fractionation. If direct (conjugated) bilirubin is >35% of total, discontinue pazopanib.
Concomitant use of pazopanib and simvastatin increases risk of ALT elevations: undertake
with caution and close monitoring. Hypertension: Events of hypertension, including
hypertensive crisis, have occurred in pazopanib studies. Control BP prior to initiating
pazopanib. Monitor for hypertension early (≤1 week after starting treatment) and frequently
thereafter. Manage elevated BP with anti-hypertensive therapy and pazopanib dose
modification. Discontinue pazopanib if BP is persistently elevated (140/90 mmHg) or if arterial
hypertension is severe and persists despite anti-hypertensive therapy and dose reduction.
Posterior reversible encephalopathy syndrome (PRES) / Reversible posterior
leukoencephalopathy syndrome (RPLS): PRES/RPLS has been reported in association with
pazopanib. Patients developing PRES/RPLS should permanently discontinue pazopanib.
Cardiac dysfunction/heart failure: Consider risks/benefits of pazopanib in patients with preexisting cardiac dysfunction. Safety and pharmacokinetics of pazopanib not studied in patients
with moderate to severe heart failure or those with below normal LVEF. Events of cardiac
dysfunction (e.g. CHF and LVEF decline) have occurred in pazopanib trials. Monitor patients
for signs and symptoms of CHF. Baseline and periodic LVEF evaluation recommended. QT
prolongation and Torsade de Pointes: Use with caution in patients (i) with history of QT
interval prolongation, (ii) taking antiarrythmics or other medications that may prolong QT
interval or (iii) with relevant pre-existing cardiac disease. Baseline and periodic ECGs, and
maintenance of electrolytes within normal range recommended. Arterial thrombotic events:
Use with caution in patients at increased risk for these events. Base treatment decision on
individual patient’s benefit/risk assessment. Venous thromboembolic events (VTEs): VTEs
including venous thrombosis and fatal PE have occurred in pazopanib trials. Thrombotic
microangiopathy (TMA): (including thrombotic thrombocytopenic purpura and haemolytic
uraemic syndrome) has been reported in clinical trials of pazopanib. Patients developing TMA
should permanently discontinue pazopanib. Reversal of effects of TMA has been observed
after pazopanib treatment was discontinued. Haemorrhagic events: Not recommended in
patients with history of haemoptysis, cerebral, or significant GI haemorrhage in past 6 months.
Use with caution in patients with significant risk of haemorrhage. GI perforations and fistula:
Use with caution in patients at risk for GI perforation or fistula. Wound healing: Stop treatment
≥7 days prior to surgery. Resume after surgery based on clinical judgement of adequate
wound healing. Discontinue pazopanib in patients with wound dehiscence. Hypothyroidism:
Baseline measurement of thyroid function recommended prior to start of pazopanib treatment;
monitor periodically during treatment. Monitor patients for signs and symptoms of thyroid
dysfunction and manage as per standard medical practice. Proteinuria: Baseline and periodic
urinalysis recommended. Monitor patients for worsening proteinuria. Discontinue pazopanib if
Grade 4 proteinuria develops. Pneumothorax: Observe patients closely for signs and
symptoms of pneumothorax. Infections: Cases of serious infection (with/without neutropenia)
reported. Interactions Avoid concomitant use with strong inhibitors of CYP3A4, pglycoprotein (P-gp) or breast cancer resistance protein (BCRP) and CYP3A4 inducers.
Hyperglycaemia observed during concomitant administration with ketoconazole. Avoid coadministration with medicines that increase gastric pH (e.g. PPIs and H2 receptor antagonists)
unless medically necessary. Undertake concomitant administration with uridine diphosphate
glucuronosyl transferase 1A1 (UGT1A1) substrates and simvastatin (and other statins) with
caution. Avoid grapefruit juice during pazopanib treatment. Pregnancy and lactation No
adequate data on use in pregnant women. Not to be used unless clearly necessary;
appropriate contraception advised. Not known whether pazopanib excreted in human milk;
breastfeeding should be discontinued. Animal studies indicate fertility may be affected.
