A Study to Evaluate Enfortumab Vedotin Versus (vs) Chemotherapy in Subjects With Previously Treated Locally Advanced or Metastatic Urothelial Cancer (EV-301)
An Open-Label, Randomized Phase 3 Study to Evaluate Enfortumab Vedotin vs Chemotherapy in Subjects With Previously Treated Locally Advanced or Metastatic Urothelial Cancer (EV-301)
The purpose of this study was to compare the overall survival (OS) of participants with locally advanced or metastatic urothelial cancer treated with enfortumab vedotin (EV) to the OS of participants treated with chemotherapy.
This study compared progression-free survival on study therapy (PFS1); the overall response rate (ORR) and the disease control rate (DCR) per Response Evaluation Criteria in Solid Tumors (RECIST) V1.1 of participants treated with EV to participants treated with chemotherapy.
In addition, this study evaluated the duration of response (DOR) per RECIST V1.1 of EV and chemotherapy and assessed the safety and tolerability of EV, as well as, the quality of life (QOL) and Patient Reported Outcomes (PRO) parameters.

Measure Description |
Time Frame |
---|---|---|
Overall Survival (OS)
Time Frame: From randomization until the analysis cut-off date of 15-Jul-2020 (median OS follow-up was 11.10 months)
|
OS was defined as the time from the date of randomization until the documented date of death from any cause.
OS was analyzed using Kaplan-Meier estimates.
Participants who were still alive at the time of data cutoff date were to be censored at the last known alive date or at the data cutoff date, whichever was earlier.

From randomization until the analysis cut-off date of 15-Jul-2020 (median OS follow-up was 11.10 months)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Progression Free Survival on Study Therapy (PFS1) as Per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1)
Time Frame: From randomization until the analysis cut-off date of 15-Jul-2020 (median OS follow-up was 11.10 months)
|
PFS: time from date of randomization until date of documented radiological disease progression (PD) per investigator based on RECIST V1.1, or until death due to any cause, whichever occurred first.
PD: >= 20% increase in sum of diameters of target lesions taking as reference the smallest sum, and sum must also demonstrate an absolute increase of >= 5 mm.
Appearance of 1 or more new lesions is also considered progression.
A participant who neither progressed nor died was censored at date of last radiological assessment (RA)/ date of randomization if no post-baseline RA was available.
Participants who received any further anticancer therapy (ACT) for disease before radiological progression was censored at date of last RA before ACT started and participants who had PD/death after >=2 missed RAs were censored at last RA prior to 2 or more missed RAs.
Kaplan-Meier estimates was used.
Median time of follow-up for PFS was based on data cut-off & is same as median follow-up time for OS.
|
From randomization until the analysis cut-off date of 15-Jul-2020 (median OS follow-up was 11.10 months)
|
Overall Response Rate (ORR) as Per RECIST V1.1
Time Frame: From randomization until the analysis cut-off date of 15-Jul-2020 (median OS follow-up was 11.10 months)
|
ORR was defined as the percentage of participants with complete response (CR) or partial response (PR) based on the RECIST v1.1.
CR was defined as disappearance of all target and nontarget lesions.
Any pathological lymph nodes (whether target or nontarget) must have reduction in short axis to < 10 mm from baseline measurement.
PR was defined as at least a 30% decrease in the sum of diameters (longest for nonnodal lesions, short axis for nodal lesions) of target lesions taking as reference to the baseline sum of diameters.
ORR was analysed using exact method based on binomial distribution (Clopper-Pearson).
Median time of follow up for ORR was based on data cut-off and is same as median follow-up time for OS.
|
From randomization until the analysis cut-off date of 15-Jul-2020 (median OS follow-up was 11.10 months)
|
Disease Control Rate (DCR) as Per RECIST V1.1
Time Frame: From randomization until the analysis cut-off date of 15-Jul-2020 (median OS follow-up was 11.10 months)
|
DCR was defined as the percentage of participants with a CR, PR or a stable disease (SD) based on RECIST v1.1.
CR was defined as disappearance of all target and nontarget lesions.
Any pathological lymph nodes (whether target or nontarget) must have reduction in short axis to < 10 mm from baseline measurement.
PR was defined as at least a 30% decrease in the sum of diameters (longest for nonnodal lesions, short axis for nodal lesions) of target lesions taking as reference to the baseline sum of diameters.
SD was defined as neither sufficient decrease to qualify for PR nor sufficient increase to qualify for progressive disease taking as reference the smallest sum of diameters while on study drug.

Duration of Response (DOR) as Per RECIST V1.1
Time Frame: From date of first objective response until the analysis cut-off date of 15-Jul-2020 (median OS follow-up was 11.10 months)
|
DOR: time from the date of the first CR/PR (whichever is first recorded) that was subsequently confirmed as assessed by investigator to the date of documented PD or death due to any cause whichever occurred first.
If a participant has neither progressed nor died, the participant was censored at the date of last RA or at the date of first CR/PR if no subsequent post-baseline RA was available.
Participants who received any further ACT for the disease before radiological progression were censored at the date of the last RA before the ACT started.
In addition, participants who had PD/death after >= 2 missed RAs were censored at the last RA prior to the 2 or more missed RAs.
Kaplan-Meier estimates was used.
Median time of follow up for DOR was based on data cut-off and is same as median follow-up time for OS.
CR/PR and PD were defined in ORR and PFS1 endpoints, respectively.

Change From Baseline to Week 12 in European Organisation for Research and Treatment of Cancer [EORTC] Quality of Life Questionnaire Global Health Status (QL2 Score)
Time Frame: Baseline and week 12
|
EORTC QLQ-C30 is a generic questionnaire consisting of 30 items.
The instrument yields functional scales (physical, role, emotional, cognitive, social), symptom scales/items (fatigue, Nausea and vomiting, pain, dyspnea, insomnia, appetite loss, constipation, diarrhea), global health status, and financial impact score.
Most items are scored 1 ("not at all") to 4 ("very much") except for the items contributing to the global health status/QoL, which are scored 1 ("very poor") to 7 ("excellent").
The recall period for each question is "during the past week".
All raw domain scores are linearly transformed to a 0-100 scale with higher scores on symptoms indicate a worse health state.
Higher scores on the global health status and functioning scales indicate better health status/function.

Change From Baseline to Week 12 in EuroQOL 5-dimension 5-level Questionnaire [EQ-5D-5L] Visual Analog Scale (VAS)
Time Frame: Baseline and week 12
|
EQ-5D-5L is a health status instrument for self-reported assessment of 5 domains of health: mobility, self-care, usual activities, pain/discomfort and anxiety/depression.
Each domain is rated by selecting 1 of 5 standardized categorizations ranging from no problem to extreme problem.
The final question is a visual analogue scale (VAS) to rank health status from 0 (best health imaginable) to 100 (worst health imaginable).

Number of Participants With Treatment Emergent Adverse Events
Time Frame: From first dose up to 30 days after last dose (Median (range) time on study drug was 4.99 (0.5, 19.4) months in enfortumab vedotin and 3.45 (0.2, 15.0) months in chemotherapy group)
|
An AE is any untoward medical occurrence in a participant temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.
An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product.
A TEAE is defined as an AE observed or worsened after starting administration of the study drug.

From first dose up to 30 days after last dose (Median (range) time on study drug was 4.99 (0.5, 19.4) months in enfortumab vedotin and 3.45 (0.2, 15.0) months in chemotherapy group)
|
Number of Participants With ECOG Performance Status
Time Frame: End of treatment (EOT) (Median (range) time on study drug was 4.99 (0.5, 19.4) months in enfortumab vedotin and 3.45 (0.2, 15.0) months in chemotherapy group)
|
ECOG performance status was measured on an 6 point scale. 0-Fully active, able to carry on all pre-disease performance without restriction.
|
End of treatment (EOT) (Median (range) time on study drug was 4.99 (0.5, 19.4) months in enfortumab vedotin and 3.45 (0.2, 15.0) months in chemotherapy group)
