What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores a new treatment, pumitamig, combined with chemotherapy to determine its effectiveness for certain types of breast cancer. Participants will be randomly assigned to receive either pumitamig plus chemotherapy or a placebo (a harmless pill resembling the real drug) plus chemotherapy. The trial targets individuals with advanced breast cancer that cannot be treated with a specific type of immunotherapy. Those whose breast cancer has spread or recurred and who have not succeeded with other treatments might qualify. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants an opportunity to contribute to potentially groundbreaking treatment advancements.

Do I need to stop my current medications for the trial?

The trial protocol does not specify if you need to stop your current medications. However, you cannot have received certain treatments like systemic anticancer therapy for advanced disease or high-dose corticosteroids recently. It's best to discuss your specific medications with the trial team.

Is there any evidence suggesting that Pumitamig is likely to be safe for humans?

Research has shown that pumitamig, when combined with chemotherapy, is generally safe. In past studies, most patients handled the treatment well. Importantly, no new safety issues emerged, and few patients discontinued the treatment due to side effects. These results suggest that pumitamig is safe for people, although individual experiences may differ.12345

Why do researchers think this study treatment might be promising?

Pumitamig is unique because it combines with the treatment of physician's choice (TPC) chemotherapy to target breast cancer cells more precisely. Unlike standard treatments that rely solely on chemotherapy, Pumitamig introduces a new active ingredient, BNT327, which may enhance the effectiveness of the chemotherapy regimen. Researchers are excited about this treatment because it could offer improved outcomes by potentially increasing the cancer-killing power of existing chemotherapy options.

What evidence suggests that pumitamig might be an effective treatment for breast cancer?

Research has shown that Pumitamig, which participants in this trial may receive, may help treat breast cancer. In one study, when combined with chemotherapy, 78.6% of patients with advanced triple-negative breast cancer responded positively. Another report found a 76.3% positive response rate in a group of patients evaluated for effectiveness. Pumitamig is a treatment that enhances the immune system's ability to target cancer cells. These results suggest that Pumitamig could be effective for breast cancer patients, particularly those with more aggressive forms.34678

Are You a Good Fit for This Trial?

This trial is for adults with a specific type of advanced breast cancer called Triple-Negative or ER-low/HER2-negative. They must have at least one measurable tumor and cannot be eligible for certain immunotherapy plus chemo treatments based on their PD-L1 status. Participants need to provide a tissue sample and be in good physical condition (ECOG 0 or 1).

Inclusion Criteria

I have a tumor that can be measured by medical imaging.
I can't have specific immunotherapy plus chemotherapy due to my tumor's PD-L1 status.
My breast cancer is either triple-negative or has low hormone receptor levels and is not HER2-positive.

What Are the Treatments Tested in This Trial?

Interventions

  • Pumitamig
Trial Overview The ROSETTA Breast-01 trial is testing the effectiveness and safety of Pumitamig, combined with chemotherapy drugs like Nab-paclitaxel/Paclitaxel, Gemcitabine, Carboplatin, or Eribulin versus a placebo with those chemotherapies. It's a Phase III study where patients are randomly assigned to either treatment without knowing which one they receive.
