Study of Sacituzumab Govitecan Versus Treatment of Physician's Choice in Participants With Endometrial Cancer After Platinum-Based Chemotherapy and Immunotherapy

Phase 3
Recruiting
Conditions
Endometrial Cancer
Interventions
Registration Number
NCT06486441
Lead Sponsor
Gilead Sciences
Brief Summary

The goal of this clinical study is to find out how the study drug, sacituzumab govitecan (SG) works in participants with endometrial cancer who have received prior treatment with platinum-based chemotherapy and immunotherapy, versus the treatment of physician's choice (TPC).

The primary objectives of this study are to evaluate the effect of SG compared to TPC on progression-free survival (PFS) as assessed by blinded independent central review (BICR) and overall survival (OS).

  • Received any prior treatment with a Trop-2-directed antibody-drug conjugate (ADC).
  • Have an active second malignancy.
  • Have an active serious infection requiring systemic antimicrobial therapy.
  • Have active chronic inflammatory bowel disease (ulcerative colitis, Crohn's disease) or gastrointestinal perforation within 6 months prior to randomization.
  • Have a positive serum pregnancy test or are breastfeeding for participants who are assigned female at birth.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.

Primary Outcome Measures
NameTimeMethod
Progression-Free Survival (PFS) As Assessed by Blinded Independent Central Review (BICR)Up to approximately 27 months

PFS, defined as the time from the date of randomization until the date of objective progressive disease (PD), as assessed by BICR per Response Evaluation Criteria in Solid Tumors (RECIST v1.1), or death from any cause, whichever comes first.

Overall Survival (OS)Up to approximately 47 months

Overall survival (OS) is defined as time from the date of randomization until death due to any cause.

Secondary Outcome Measures
NameTimeMethod
Change from Baseline in the Physical Functioning Domain of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 Version 3.0 (EORTC QLQ-C30) at Week 13Baseline, Week 13

The EORTC QLQ-C30 is a questionnaire to assess quality of life of cancer patients, it is composed of 30 questions (items) resulting in 5 functional scales, 1 global health status scale, 3 symptom scales, and 6 single items. Scoring of the QLQ-C30 is performed according to QLQ-C30 Scoring manual. The physical functioning scale range in score from 0 to 100. Higher score denote a better level of functioning (i.e. a better state of the participant).

Change from baseline in Global Health Status (GHS)/Quality of Life (QoL) Domain of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 Version 3.0 (EORTC QLQ-C30) at Week 13Baseline, Week 13

The EORTC QLQ-C30 is a questionnaire to assess quality of life of cancer patients, it is composed of 30 questions (items) resulting in 5 functional scales, 1 global health status scale, 3 symptom scales, and 6 single items. Scoring of the QLQ-C30 is performed according to QLQ-C30 Scoring manual. Global health status score ranges from 0 to 100. Higher score denote a better level of functioning (i.e. a better state of the participant).

ORR as Assessed by InvestigatorUp to approximately 47 months

ORR is defined as the percentage of participants who have achieved a CR or PR as best overall response that is confirmed ≥ 4 weeks after initial documentation of response as assessed by investigator per RECIST v1.1

Clinical Benefit Rate (CBR) as Assessed by BICR and InvestigatorUp to approximately 47 months

CBR is defined as the percentage of participants with best overall response of CR or PR that is confirmed ≥ 4 weeks after initial documentation of response or durable stable disease (SD; duration of SD ≥ 6 months from randomization to disease progression), as assessed by BICR and investigator per RECIST v1.1.

Objective Response Rate (ORR) as Assessed by BICRUp to approximately 47 months

ORR, defined as the percentage of participants who have achieved a CR or PR as best overall response that is confirmed ≥ 4 weeks after initial documentation of response as assessed by BICR per RECIST v1.1.

PFS as Assessed by InvestigatorUp to approximately 27 months

PFS is defined as the time from the date of randomization until the date of objective PD, as assessed by investigator per RECIST v1.1, or death from any cause, whichever comes first

Duration of Response (DOR) as Assessed by BICR and InvestigatorUp to approximately 47 months

DOR is defined as the time from the first documentation of CR or PR to the earlier of the first documentation of definitive PD as assessed by BICR and investigator per RECIST v1.1, or death from any cause, whichever comes first.

Percentage of Participants Experiencing Treatment-Emergent Adverse Events (TEAEs)First dose date up to 30 days post last dose (Up to Up to approximately 47 months)
Percentage of Participants Experiencing Clinical Laboratory AbnormalitiesFirst dose date up to 30 days post last dose (Up to Up to approximately 47 months)
