A Clinical Trial of Sac-TMT in People With Non-HRD Positive Advanced Ovarian Cancer (MK-2870-021)
(TroFuse-021)
What this study is about
Researchers are looking for new ways to treat ovarian cancer (OC). 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.
View original scientific description
Researchers are looking for new ways to treat ovarian cancer (OC). 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.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
