Current treatment for OC may start with surgery to remove as much of the cancer as possible. After surgery, people may receive chemotherapy. After chemotherapy, standard care options may include: \* Maintenance treatment, which is used after another therapy to keep the cancer from growing, spreading, or coming back. Bevacizumab is a targeted therapy used as standard maintenance treatment. Targeted therapy works to control how specific types of cancer cells grow and spread. \* Observation, which is watching to see if cancer grows or worsens The study medicine, sacituzumab tirumotecan (also called sac-TMT), is a targeted therapy. The goal of this study is to learn if people who receive sac-TMT maintenance treatment with or without bevacizumab live longer without the cancer getting worse than people who receive standard care.

Progression-Free Survival (PFS) Timeframe: Up to approximately 49 months PFS is defined as the time from randomization to the first documented progressive disease (PD) per Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 by blinded independent central review (BICR) or death due to any cause, whichever occurs first. Per RECIST 1.1, 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 have demonstrated an absolute increase of ≥5 mm. The appearance of one or more new lesions is also considered PD. ### Secondary outcomes 1. Overall Survival (OS) Timeframe: Up to approximately 78 months OS is defined as the time from randomization to death due to any cause. 2. Progression-Free Survival 2 (PFS2) Timeframe: Up to approximately 78 months PFS2 as assessed by investigator 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. 3. Number of Participants Who Experience an Adverse Event (AE) Timeframe: Up to approximately 78 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. 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 study intervention. 4. Number of Participants Who Discontinue Study Treatment Due to an AE Timeframe: Up to approximately 78 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. 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 study intervention. 5. Change From Baseline in Global Health Status/Quality of Life (GHS/QoL) Combined Score (Items 29 and 30) Using the European Organisation for Research and Treatment of Cancer QoL Questionnaire-Core 30 (EORTC QLQ-C30) Timeframe: Baseline and up to approximately 78 months EORTC QLQ-C30 is a questionnaire to assess the overall quality of life (QoL) 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 combined score will be presented. 6. Change From Baseline in Physical Functioning Combined Score (Items 1 to 5) Using EORTC QLQ-C30 Timeframe: Baseline and up to approximately 78 months EORTC QLQ-C30 is a questionnaire to assess the overall QoL of cancer patients. Participant responses to 5 questions about their physical functioning are scored on a 4-point scale (1 = Not at All to 4 = Very Much). The combined score is computed by averaging the raw scores of the 5 questions and then applying a linear transformation to standardize the average score, so that the combined score ranges from 0 to 100\. A higher score indicates a better outcome. The change from baseline in the EORTC QLQ-C30 physical functioning combined score will be presented. 7. Change From Baseline in Role Functioning Combined Score (Items 6 and 7) Using EORTC QLQ-C30 Timeframe: Baseline and up to approximately 78 months EORTC QLQ-C30 is a questionnaire to assess the overall QoL of cancer patients. Participant responses to 2 questions about their role functioning are scored on a 4-point scale (1 = Not at All to 4 = Very Much). The combined score is computed by averaging the raw scores of the 2 items and then applying a linear transformation to standardize the average score, so that the combined score ranges from 0 to 100\. A higher score indicates a better outcome. The change from baseline in the EORTC QLQ-C30 role functioning combined score will be presented. 8. Change From Baseline in Abdominal/Gastrointestinal (GI) Symptoms Combined Score Using the EORTC QLQ-Ovarian Cancer Module 28 (OV28) Timeframe: Baseline and up to approximately 78 months EORTC QLQ-OV28 is an OC-specific module to supplement the EORTC QLQ-C30\. Participant responses to the 6 abdominal/GI symptoms scale questions are scored on a 4-point scale (1=not at all, 4=very much). The combined score is computed by averaging the raw scores of the 6 items and then applying a linear transformation to standardize the average score, so that the combined score ranges from 0 to 100\. The change from baseline in abdominal and gastrointestinal symptoms (EORTC QLQ-OC28 Items 31-36) score will be presented. A lower score indicates a better outcome.
