COMPARZ Results COMParing the efficacy, sAfety and toleRability of paZopanib vs. sunitinib in first-line advanced and/or metastatic renal cell carcinoma VEG UK/PAZ/0029/13 February 2013 Insert: Presenter name Insert: Job role and place of work Insert: Date of presentation GSK has been involved in the preparation of this presentation Prescribing information can be found at the end of the main presentation
Treatment options for advanced RCC have been revolutionised in a short period of time… EMA = European Medicines Agency High-dose interleukin-2 Sorafenib IFN-α Sunitinib Bevacizumab + IFN-α Temsirolimus Pazopanib Everolimus Axitinib Timelines based on EMA approval
Pazopanib indication 1. Votrient Summary of Product Characteristics. January 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 disease 1 Pazopanib’s licence is conditional pending further clinical data from GSK, including the outcome of COMPARZ
Pazopanib NICE Technology Appraisal Guidance (TA 215) 1 1. NICE. Pazopanib for the first-line treatment of advanced renal cell carcinoma. Final appraisal guidance no February 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
Pazopanib Scottish Medicines Consortium Advice No. 676/11 1 Pazopanib is accepted for restricted use within NHS Scotland for the first-line 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. 1. Scottish Medicines Consortium. Pazopanib 200mg, 400mg film-coated tablets (Votrient). Advice no. 676/11. March 2011
COMPARZ Study Background
Rationale 1.Sternberg CN et al. J Clin Oncol 2010;28: COMPARZ was initiated in 2008 –Provide comparative data to inform and aid prescribers and payers In 2010 pazopanib was granted a conditional approval in the EU based on the VEG data (pazopanib vs. placebo) 1 –As COMPARZ was already underway it became part of the obligation of the conditional approval
Primary endpoint obligations Protocol-defined primary endpoint –Non inferiority in PFS at a margin of 1.25 (upper 95% CI) EMA-defined primary endpoint –Non inferiority in PFS at a margin of 1.22 (upper 95% CI) –Linked to pazopanib’s conditional marketing authorisation –Subsequently linked to pazopanib’s NICE and SMC guidance –EMA, NICE and SMC have been informed of the results and GSK await to hear from them

ESMO 2012 oral presentation; abstract LBA8_PR.
Why did GSK use a non-inferiority trial design? To establish that the efficacy of pazopanib is non inferior to sunitinib A non-inferiority study is designed to show that the experimental treatment is not less effective than an existing treatment, by more than a pre-specified amount 1 –This amount is known as the non-inferiority margin –To show non-inferiority, the upper bound of the 95% CI should lie entirely to the left of the non-inferiority margin (in this case, 1.25 as defined in the protocol, 1.22 as defined by the EMA which is linked to the NICE/SMC guidance) 1.CHMP. Guideline on the choice of the non-inferiority margin. EMEA 2005.
Why did GSK use a non-inferiority trial design? With a margin of 1.25, at least 631 PFS events (independently reviewed) were required to provide 80% power GSK took the risk to evaluate pazopanib vs. the standard of care Non-inferiority shown Inferiority shown New agent better 1New agent worse Treatment difference Hazard Ratio (HR) 1.25
Disease assessments (CT/MRI) performed at: –Baseline –Every 6 weeks to week 24 –Every 12 weeks thereafter until disease progression, death or unacceptable toxicity Other assessments performed in 6-week cycles –Safety Baseline, day 28 & day 42 of every cycle through to cycle 9, day 42 of every cycle from cycle 10 –Patient-reported outcomes Baseline (except for CTSQ), day 28 every cycle through to cycle 9, day 42 of every cycle from cycle 10 –FACIT-Fatigue –Functional Kidney Symptom Index (FKSI-19) –Cancer Therapy Satisfaction Questionnaire (CTSQ) –Supplementary Quality of Life Questionnaire (SQLQ) 1.Motzer R, et al.

The COMPARZ results complement the PISCES data 1 PazopanIb versus Sunitinib patient preferenCE Study in treatment naïve locally advanced or metastatic renal cell carcinoma 1 Randomised, double-blind, cross-over study over a 22 week period –Total 168 patients randomised; 114 patients in primary analysis population Patients completed the patient preference questionnaire at the end of the study before unblinding 1. Escudier BJ, Porta C, Bono P, et al. Abstract and oral presentation at the American Society of Clinical Oncology Annual Congress J Clin Oncol 2012; 30 (suppl.): Abstract CRA4502.
The COMPARZ results complement the PISCES data – continued 1 Patients (%) 90% CI (for difference): 37.0%-61.5%; p< % (n=80) 22% (n=25) 8% (n=9) *Question asked: “Now that you have completed both treatments, which of the two drugs would you prefer to continue to take as the treatment for your cancer, assuming that both drugs will work equally well in treating your cancer?” (patients selected either first treatment, second treatment or no preference) 1. Escudier BJ, Porta C, Bono P, et al. Abstract and oral presentation at the American Society of Clinical Oncology Annual Congress J Clin Oncol 2012; 30 (suppl.): Abstract CRA4502.
The COMPARZ results complement the PISCES data – continued 1 The most important symptom which influenced this preference –Pazopanib: Less fatigue (21 of the 80 patients who preferred pazopanib) –Sunitinib: Less diarrhoea (6 of the 25 patients who preferred sunitinib) The most common adverse events (all grade) reported in ≥30% of patients receiving pazopanib and sunitinib respectively were: diarrhoea 42% vs. 32%, nausea 33% vs. 30% and fatigue 29% vs. 30% 1.

Patient reported outcome tools FACIT-Fatigue (validated) –Measures severity and impact of fatigue on functioning and HRQoL experienced in past seven days 1 –Used previously to evaluate fatigue with anti-angiogenesis treatments, including assessments for sunitinib 2,3 FKSI-19 (validated) –A disease-specific measure that measures disease and treatment- related symptoms specifically in renal cancer patients 4,5,6 –Includes patient self-reports on experience of symptoms in the past seven days such as lack of energy, pain, bone-pain, shortness of breath, fatigue, blood in urine, etc. 1. Cella, Motzer, Beaumont, Rosenbloom, Rosenbloom, Rao, 2008
Patient reported outcome tools Cancer Therapy Satisfaction Questionnaire (CTSQ; validated) –A questionnaire which has been well-validated for use in assessing patients’ satisfaction with various key aspects of undergoing cancer therapy (e.g. side effects, convenience of regimens, etc.) 1 Supplementary Quality of Life Questionnaire (unvalidated) –An SQLQ form has been included in the trial which includes 5 question items. –There are two questions that ask for patients self-reports on severity of symptoms and impact of these symptoms which refer to mouth and throat soreness and also to hand and foot soreness. –The questions on mouth and throat soreness are adapted from the Oral Mucositis Daily Questionnaire (OMDQ), a validated questionnaire used previously in clinical trials 2-5 –One question refers to days missed from work specifically due health problems. This question was designed to follow general format of work productivity assessments in the National Health and Nutrition Survey (NHANES), which clearly refer to impact on work due to health (i.e., physical, mental, or emotional) 6 1.

Relative Risk in Adverse Events AE occurrence ≥10% in either arm; 95% CI for RR does not cross 1 Forest plot To be included on the plot, the AE needs to meet two criteria: Firstly, the absolute occurrence in either treatment arm needs to be >10% Secondly, there needs to be a statistically significant difference in the risk of the adverse event between the two treatment arms – i.e. occurrence >10% and 95% confidence interval for the relative risk does not cross 1
VEG Asian sub-study COMPARZ was originally designed with a non-inferiority margin (upper bound 95% CI) of EMA requested a tighter margin (upper bound 95% CI) of 1.22, which would require more events than COMPARZ could deliver alone. Therefore the EMA agreed that GSK could take a step-wise approach to pool the results from COMPARZ and the identical Asian sub-study to meet the required number of events The trials were designed almost identically and therefore the studies could be combined for analysis without statistical concern Asian sub-study was originally conducted to meet the regulatory and reimbursement requirements of China, South Korea and Taiwan to evaluate the efficacy and safety of pazopanib in these ethnic groups Additional patients were also required due to: –Drop-out due to adverse events or other reasons (decision by patient or investigator, lost to follow-up) prior to assessment of progression –Exclusion due to discordance between the independent review and investigator assessments of progression The analysis for COMPARZ is based on 927 patients plus 183 from the Asian sub- study
EQ5D data from PISCES 1 1.Cella D, Kaiser K, Beaumont J, et al. Quality of life (QOL) among renal cell carcinoma (RCC) patients in a randomised double blind cross- over patient preference study of pazopanib (P) versus sunitinib (S). Abstract and poster presentation at European Society of Medical Oncology Congress Abstract no. 792PD The EQ-5D data presented at ESMO 2012 were inconclusive EQ-5D assessment showed that utility scores deteriorated in pazopanib-treated patients in treatment period 1, but the deterioration in period 2 was numerically greater in sunitinib-treated patients compared with those on pazopanib
