PFS, Full Analysis Set -Durvalumab + Tremelimumab Combination Therapy vs SoC and Durvalumab Mono Therapy vs SoC

Study of MEDI4736 (Durvalumab) With or Without Tremelimumab Versus Standard of Care Chemotherapy in Urothelial Cancer · Source last updated 2026-07-14

Results reported by the registry submitting party. Population, time horizon, units and missing values must be read together.

Measure: MEDIAN
Unit: Months
Interval / dispersion: 95% Confidence Interval
Time frame: Tumour scans performed at baseline then every 8 weeks since randomization until confirmed disease progression. Assessed up to the data cut-off date (27JAN2020, a maximum of 5 years).

What was measured

Progression free survival (PFS) (per RECIST 1.1, as assessed by investigator) was defined as the time from the date of randomization until the date of objective disease progression or death (by any cause in the absence of progression) regardless of whether the patient withdraws from randomized therapy or receives another anticancer therapy prior to progression. Median PFS was calculated using the Kaplan-Meier technique.

Analysis population: Full analysis set (FAS) included all randomized participants analyzed on an intent-to-treat (ITT) basis.
