Sacituzumab Tirumotecan + Pembrolizumab for Endometrial Cancer
(TroFuse-033 Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests new treatments for advanced or recurring endometrial cancer with specific proteins present in the cancer cells. The study examines whether combining sacituzumab tirumotecan, an antibody drug targeting cancer cells, with pembrolizumab, an immunotherapy, can help patients live longer without their cancer worsening, compared to pembrolizumab alone. Participants should have endometrial cancer that has returned or spread and should not have received previous treatments targeting the proteins involved in this study. As a Phase 3 trial, this study represents the final step before FDA approval, offering patients a chance to access potentially effective treatments earlier.
Will I have to stop taking my current medications?
The trial information does not specify if you need to stop taking your current medications. However, it mentions that prior hormonal therapy for endometrial carcinoma must be stopped at least one week before starting the trial treatment.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that sacituzumab tirumotecan (sac-TMT) has a manageable safety profile for patients with endometrial and ovarian cancers. While some side effects occur, they are generally manageable.
Sac-TMT is an antibody drug conjugate (ADC), meaning it specifically targets cancer cells, helping to protect healthy cells. In past studies, most side effects were mild to moderate, such as fatigue or nausea.
Pembrolizumab, a well-known immunotherapy drug, is already approved for several types of cancer. It aids the immune system in fighting cancer cells. Most people tolerate it well, though some may experience fatigue or mild skin reactions.
Researchers are studying the combination of sac-TMT with pembrolizumab to determine if it improves treatment outcomes. Early results suggest that adding sac-TMT does not significantly increase severe side effects compared to pembrolizumab alone.
Prospective trial participants should discuss potential risks and benefits with their doctor. Current data supports that both treatments have been tolerable in past studies.12345Why are researchers excited about this trial's treatments?
Researchers are excited about Sacituzumab Tirumotecan + Pembrolizumab for endometrial cancer because these treatments offer a fresh approach compared to traditional therapies. Most current treatments involve surgery, radiation, and chemotherapy, which primarily attack rapidly dividing cells. Unlike these, Sacituzumab Tirumotecan targets a specific protein, Trop-2, found on cancer cells, allowing it to deliver chemotherapy directly to the tumor. Meanwhile, Pembrolizumab is an immunotherapy that helps the immune system recognize and fight cancer cells more effectively. Together, these treatments have the potential to enhance precision in targeting cancer cells, possibly leading to better outcomes with fewer side effects.
What evidence suggests that this trial's treatments could be effective for endometrial cancer?
Research has shown that sacituzumab tirumotecan (sac-TMT) holds promise in treating endometrial cancer, with patients experiencing an average of 5.7 months before the cancer worsens. The treatment shrinks tumors in about 31% to 34% of patients. In this trial, some participants will receive sac-TMT alone, while others will receive it with pembrolizumab. Adding pembrolizumab to standard treatment significantly slows cancer progression in advanced cases. This combination is considered an effective and safe option for managing this cancer. Together, sac-TMT and pembrolizumab have demonstrated lasting and encouraging results in studies, suggesting they could be a strong combination for treating advanced endometrial cancer.678910

Are You a Good Fit for This Trial?
This trial is for individuals with advanced or recurrent endometrial cancer that still has certain normal proteins (pMMR). Participants must have a confirmed diagnosis, measurable disease according to specific criteria, and no prior systemic therapy for their cancer except under certain conditions like one round of platinum-based chemotherapy or hormonal therapy discontinued at least a week before.Inclusion Criteria
