What was measured

TTD was defined as time (in months) from the first dose of study treatment to the date of deterioration of FKSI-DRS Score. The FKSI-DRS was a questionnaire that asked the participant to rate 9 kidney cancer-related symptoms: lack of energy, fatigue, weight loss, pain, bone pain, shortness of breath, cough, fever, or blood in the urine. Each item was scored on a 5-point scale (0=not at all to 4=very much). FKSI-DRS total score ranged from 0 (most severe symptoms) to 36 (no symptoms) with a higher score indicating a better outcome. Deterioration was defined as a 3-point decrease (i.e. lower score) in symptom score and the time to true deterioration was the time to first onset of 3 or more decreases from baseline with confirmation under right-censoring rule (the last observation). The time to true deterioration as measured in months is presented.

Analysis population: All randomized participants who received at least 1 dose of study medication and completed at least 1 questionnaire assessment.

Groups in this outcome

Pembrolizumab + Axitinib

Participants received pembrolizumab 200 mg intravenously every 3 weeks PLUS axitinib 5 mg orally twice daily.

Sunitinib

Participants received sunitinib 50 mg orally once daily for 4 weeks and then were off treatment for 2 weeks.
