Trial Outcomes & Findings for Patient Preference Study of Pazopanib Versus Sunitinib in Advanced or Metastatic Kidney Cancer (NCT NCT01064310)

NCT ID: NCT01064310

Last Updated: 2017-04-17

Results Overview

The PPQ is used to measure participants' preference for pazopanib or sunitinib for renal cell carcinoma management and is used to determine a participant's preference for 1 of the 2 drugs given in the 2 double-blind treatment periods. Participants were asked to select 1 of the following: 1. prefer the drug taken as the first treatment; 2. prefer the drug taken as the second treatment; or 3, no preference. Those participants who indicated a preference were asked to select the factors that had an influence on their treatment preference, as well as the most important reason for their preference.

Measure
Sunitinib 50 mg Followed by Pazopanib 800 mg
Period 1: Participants received 4 overencapsulated capsules of sunitinib, each containing 12.5 milligrams (mg) of sunitinib, once daily (OD) orally for 4 weeks, followed by 2 weeks off treatment (matching placebo capsules to maintain blind), followed by 50 mg (4 x 12.5 mg) OD orally for 4 weeks. Period 1 was followed by a 2-week wash-out period in which no treatment was given. Period 2: Participants received 4 overencapsulated tablets of pazopanib, each containing 200 mg of pazopanib, OD orally for 10 weeks. Study drugs were taken without food at least one hour before or two hours after a meal. The capsules were swallowed whole and not crushed or broken. The time of day the study drugs were taken remained relatively constant.

PRIMARY outcome

Timeframe: End of treatment of both study drugs (maximum of 22 weeks)

Population: Modified-Intent-to-Treat (mITT) Population (used for the primary analysis): participants who received at least one dose of study treatment from each treatment period and who did not have documented progressive disease (PD) at the end of Treatment Period 1 and completed the patient preference questionnaire.

The PPQ is used to measure participants' preference for pazopanib or sunitinib for renal cell carcinoma management and is used to determine a participant's preference for 1 of the 2 drugs given in the 2 double-blind treatment periods. Participants were asked to select 1 of the following: 1. prefer the drug taken as the first treatment; 2. prefer the drug taken as the second treatment; or 3, no preference. Those participants who indicated a preference were asked to select the factors that had an influence on their treatment preference, as well as the most important reason for their preference.

SECONDARY outcome

Timeframe: Day 1 (Period [P] 1 Pre-dose); Weeks 2, 4, 6, 8, and 10 of P 1; during 2-week Wash-out Period (Study Weeks 11 and 12); Weeks 2, 4, 6, and 8 of P 2 (Study Weeks 14, 16, 18, 20, and 22, respectively); End of Study (Week 10 of P 2 [Study Week 22])

Population: Safety-Randomized Study Population: participants who received at least one dose of either drug regardless of treatment period. Participants who received mixed treatment within a period were excluded. Only those participants contributing data at the indicated time points were evaluated.

Change from period (P) BL is computed as participants' (par.) average post-BL fatigue score within each P minus their P-specific BL score. P 1 BL is the P 1 Pre-Dose assessment; P 2 BL is the wash-out assessment. Crossover analyses compared par. average scores on each treatment, adjusting for sequence. FACIT-Fatigue Scale: overall score (0 to 52)=the sum of scores for 13 questions. For each question, par. rated their condition for the past week on a 5-point scale: 0 (not at all) to 4 (very much). A high score indicates low fatigue. A negative change from BL represents a worsening of condition.

Study drugs were taken without food at least one hour before or two hours after a meal. The capsules were swallowed whole and not crushed or broken. The time of day the study drugs were taken remained relatively constant.

Timeframe: Day 1 (Period 1 Pre-dose); during 2-week Wash-out Period (Study Weeks 11 and 12); and End of Study (Week 10 of Period 2 [Study Week 22])

Population: Safety-Randomized Study Population. Participants (par.) who received mixed treatment within a period were excluded. Only those par. contributing data at the indicated time points were evaluated. In some instances, par. may have contributed data for one score, but not the other; thus, the number of par. analyzed reflects the entire population.

The EQ-5D is a participant-answered questionnaire measuring 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The EQ-5D has two separate components: utility score and thermometer score. The EQ-5D total utility score ranges from 0 (worst health state) to 1 (perfect health state); 1 reflects the best outcome. The thermometer score ranges from 0 (worst imaginable health state) to 100 (best imaginable health state).

Period 1: Participants received 4 overencapsulated capsules of sunitinib, each containing 12.5 milligrams (mg) of sunitinib, once daily (OD) orally for 4 weeks, followed by 2 weeks off treatment (matching placebo capsules to maintain blind), followed by 50 mg (4 x 12.5 mg) OD orally for 4 weeks. Period 1 was followed by a 2-week wash-out period in which no treatment was given. Period 2: Participants received 4 overencapsulated tablets of pazopanib, each containing 200 mg of pazopanib, OD orally for 10 weeks. Study drugs were taken without food at least one hour before or two hours after a meal. The capsules were swallowed whole and not crushed or broken.

Timeframe: End of second treatment period (maximum of 22 weeks)

Population: Safety-Randomized Study Population. Only those participants who had an dose reduction were evaluated. Participants may be counted multiple times for the same "reason" for a dose reduction if the participant had multiple reductions for the same reason.

Dose reduction of study drug was a stepwise reduction of the dose of the study drug: one less capsule was received at each step reduction. Participants were monitored for approximately 10 to 14 days at each dose level. Participants are recorded under the treatment they were receiving at the time the dose reduction was reported.

SECONDARY outcome

Timeframe: Baseline to end of study (maximum of 22 weeks)

Population: Safety-Randomized Study Population. Only those participants with adverse events leading to permanent discontinuation of study treatment were evaluated.

An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An AE that spans more than one period is considered to be an AE for each period during which the AE increased in grade. There is only one action with respect to study drug recorded for the whole event. As such, it is not always possible to determine in which study period treatment was discontinued due to the AE.

Population: Safety-Randomized Study Population. All participants who received sunitinib or pazopanib either during Period 1 or Period 2 were counted in both treatment groups (sunitinib and pazopanib). Only those participants contributing data at the indicated time points were evaluated.

When the heart beats, it contracts and pushes blood through the arteries to the rest of body. This force creates pressure on the arteries called SBP. DBP is the pressure in the arteries when the heart rests between beats. Normal levels: SBP (120 mmHg or less); DBP (80 mmHg or less). Mean change from BL for each assessment week was calculated as the average change from period BL at the specified visits (combining data across P 1 and 2 for Weeks 2 and 6). Study weeks are approximate; participants could have crossed over from P 1 to P 2 at earlier time points than specified in the protocol.

Heart rate (HR) is the number of heartbeats per unit of time, typically expressed as beats per minute. HR can vary as the body's need to absorb oxygen and excrete carbon dioxide changes, such as during exercise or sleep. A normal resting HR ranges from 60 to 100 beats per minute. Mean change from BL for each assessment week was calculated as the average change from period BL at the specified visits (combining data across P 1 and 2 for Weeks 2 and 6).
