Trial Outcomes & Findings for A Study of MOXR0916 in Combination With Atezolizumab Versus Atezolizumab Alone in Participants With Untreated Locally Advanced or Metastatic Urothelial Carcinoma Who Are Ineligible for Cisplatin-Based Therapy (NCT NCT03029832)

NCT ID: NCT03029832

Last Updated: 2019-05-31

Results Overview

PFS is defined as the time from randomization to the first occurrence of disease progression or death from any cause, whichever occurs first. Per RECIST v1.1, progressive disease is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum of diameters on study (including baseline); and an absolute increase of \>= 5 millimeter (mm) in the sum of diameters.

PRIMARY outcome

Timeframe: Up to approximately 45 months

Population: Due to early termination, no formal analyses were performed for PFS.

PFS is defined as the time from randomization to the first occurrence of disease progression or death from any cause, whichever occurs first. Per RECIST v1.1, progressive disease is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum of diameters on study (including baseline); and an absolute increase of \>= 5 millimeter (mm) in the sum of diameters.

Outcome measures

PRIMARY outcome

Timeframe: Up to approximately 45 months

Population: Due to early termination, no formal analyses were performed for OS.

Kaplan Meier estimate of median OS was defined as the time at which half of the participants had died, regardless of the cause of death.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Up to approximately 45 months

Population: Due to early termination, no formal analyses were performed for OR.

OR is defined as a complete response (CR) or partial response (PR) on two consecutive occasions \>= 4 weeks apart, as determined by the investigator according to RECIST v1.1. CR is defined as the disappearance of all target lesions. PR is defined as at least a 30% decrease in the sum of diameters of all target lesions, taking as reference the baseline sum of diameters, in the absence of CR.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Up to approximately 45 months

Population: Due to early termination, no formal analyses were performed for DOR.

DOR is defined as the time from the first occurrence of a documented objective response to disease progression or death from any cause, whichever occurs first, as determined by the investigator according to RECIST v1.1. Objective response is defined as a complete response (CR) or partial response (PR) on two consecutive occasions ≥ 4 weeks apart. CR is defined as the disappearance of all target lesions. PR is defined as at least a 30% decrease in the sum of diameters of all target lesions, taking as reference the baseline sum of diameters, in the absence of CR.

Population: Due to early termination, no formal analyses were performed for time to pain progression, pain palliation and fatigue progression.

The MDASI is a cancer-related, self-reported questionnaire consisting of 19 items assessing symptom severity and interference with different aspects of a participant's life. The MDASI items are rated from 0 to 10, with 0 indicating that the symptom is either not present or does not interfere with the participant's activities and 10 indicating that the symptom is "as bad as you can imagine" or "interfered completely" with the participant's life.
