- Brief Summary
Researchers are looking for new ways to treat people with proficient mismatch repair (pMMR) endometrial cancer (EC) that is advanced or recurrent.
* EC is a type of cancer that starts in the tissues inside the uterus (womb)
* pMMR indicates that certain normal proteins are present in the cancer cells
* Advanced means the cancer has spread locally or to other parts of the body (metastatic) and cannot be removed with surgery
* Recurrent means the cancer came back after surgery
Sacituzumab tirumotecan (also known as sac-TMT) and pembrolizumab are the study medicines. Sac-TMT is an antibody drug conjugate (ADC). An ADC attaches to specific targets on cancer cells and delivers treatment to destroy those cells.
The goal of this study is to learn if people who receive sac-TMT with pembrolizumab live longer and without the cancer getting worse compared to people who receive pembrolizumab alone.
- Detailed Description
All participants undergo an initial Induction Phase of six cycles, each cycle consisting of pembrolizumab + carboplatin + paclitaxel or docetaxel. Each cycle is three weeks. Participants whose cancer does not progress enter the Maintenance Treatment Phase and are then randomly assigned to pembrolizumab + sac-TMT or pembrolizumab monotherapy. Participants whose cancer does progress will have the possibility to enter the Subsequent Treatment Phase and are then randomly assigned to pembrolizumab + sac-TMT or sac-TMT monotherapy.

- Primary Outcome Measures
Name Time Method Maintenance Treatment: Overall Survival (OS) Up to approximately 54 months OS is defined as time from randomization to death due to any cause.
Maintenance Treatment: Progression-Free Survival (PFS) Up to approximately 44 months PFS is defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurs first as assessed by Response Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as evaluated by the blinded independent central review (BICR). PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions is also considered PD.
- Secondary Outcome Measures
Name Time Method Maintenance Treatment: Progression-Free Survival 2 (PFS2) as Assessed by Investigator Up to approximately 54 months PFS2 is defined as the time from randomization to the documented subsequent objective disease progression after initiation of new anticancer therapy or death due to any cause, whichever occurs first. PFS2 as assessed by the investigator will be presented.
Maintenance Treatment: Number of Participants Who Discontinue Study Intervention Due to an AE Up to approximately 24 months An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention.
Maintenance Treatment: Change from baseline in EORTC QLQ-C30 Physical Functioning (Items 1-5) Combined Score Baseline and up to approximately 24 months EORTC QLQ-C30 is a 30-item scale to assess the overall quality of life of cancer patients. The physical functioning score is based on participant responses to questions scored on a 4-point scale (1 = 'Not at All' to 4 = 'Very Much'). Higher scores indicate better physical functioning. The change from baseline in EORTC QLQ-C30 Physical Functioning (Items 1-5) combined score will be presented.
Maintenance Treatment: Number of Participants Who Experience One or More Adverse Events (AEs) Up to approximately 27 months An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention.
Maintenance Treatment: Change from baseline in European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) Global Health Status (Item 29) and Quality of Life (Item 30) Item Mean Score Baseline and up to approximately 24 months EORTC QLQ-C30 is a 30-item scale to assess the overall quality of life of cancer patients. Participant responses to the questions "How would you rate your overall health during the past week?" and "How would you rate your overall quality of life during the past week?" are scored on a 7- point scale (1= Very poor to 7=Excellent). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. A higher score indicates a better overall health status. The change from baseline in EORTC QLQ-C30 Items 29 and 30 mean score will be presented.
Maintenance Treatment: Change from baseline in EORTC QLQ-C30 Role Functioning (Items 6 and 7) Combined Score Baseline and up to approximately 24 months EORTC QLQ-C30 is a 30-item scale to assess the overall quality of life of cancer patients. The role functioning score is based on participant responses to questions scored on a 4-point scale (1 = 'Not at All' to 4 = 'Very Much'). Higher scores indicate better role functioning. The change from baseline in EORTC QLQ-C30 Role Functioning (Items 6 and 7) combined score will be presented.
Maintenance Treatment: Change from baseline in EORTC QLQ Endometrial Cancer Symptom Score (QLQ-EN24) Baseline and up to approximately 24 months The EORTC-QLQ-EN24 is a 24-item questionnaire developed to be used in conjunction with the EORTC-QLQ-C30 to assess the quality of life of endometrial cancer patients. Participant responses are scored on a 4-point scale (1=not at all to 4=very much). A higher score indicates a better quality of life. The change from baseline in EORTC QLQ-E24 back and pelvis pain score will be presented.
