Study of Sacituzumab Govitecan Compared to Physician's Choice Treatment in Adults with Previously Untreated Metastatic Locally Advanced, Inoperable or Metastatic Triple-Negative Breast Cancer (ASCENT-03).
Descrizione riassuntiva dello studio
This study investigates an experimental drug called Sacituzumab Govitecan in patients with previously untreated, advanced triple-negative breast cancer (TNBC). Advanced TNBC is defined as TNBC that cannot be surgically removed or has spread from the breast to other parts of the body. Sacituzumab govitecan (Trodelvy®) is currently approved by Swissmedic and other regulatory authorities for previously treated advanced TNBC. The aim of this study is to find out whether Sacituzumab Govitecan can improve the survival of patients with advanced TNBC whose tumor is not growing or spreading compared to chemotherapy (a commonly used treatment for previously untreated advanced TNBC). Eligible participants will be randomly assigned (1:1) to either the experimental treatment with Sacituzumab Govitecan OR one of the following three standard chemotherapy treatments selected by the investigator (control group): o Paclitaxel o nab-Paclitaxel o Gemcitabine with Carboplatin How long patients participate in the study overall depends on how the cancer responds to the study treatment. Active participation in the study, including treatment with the investigational drug, may continue as long as the treatment is tolerated safely and the cancer does not worsen or the study is not stopped. Participation in this study may last from one day to 4 years or longer, as long as the treatment is tolerated safely. Study participants must visit the clinic at least 2-3 times per cycle (a cycle consists of 21 or 28 days), depending on which treatment was assigned. During the follow-up period, the clinic may need to be visited every 12 weeks or more frequently.

Intervento studiato
Eligible participants will be randomly assigned (1:1) to either the experimental treatment with Sacituzumab Govitecan (Group 1) OR the control group (Group 2)
• Group 1 receives Sacituzumab Govitecan 10 mg/kg intravenously (IV) on Days 1 and 8 of 21-day cycles.
• Group 2 receives a treatment selected by the investigator from one of the following 3 chemotherapeutics:
o Paclitaxel: Paclitaxel 90 mg/m² intravenously (IV) on Days 1, 8, and 15 of 28-day cycles
o Nab-Paclitaxel: Nab-Paclitaxel 100 mg/m² intravenously (IV) on Days 1, 8, and 15 of 28-day cycles
o Gemcitabine with Carboplatin: Gemcitabine 1000 mg/m² with Carboplatin area under the curve (AUC)2 intravenously (IV) on Days 1 and 8 of 21-day cycles

Malattie studiate
Previously Untreated Metastatic Locally Advanced, Inoperable or Metastatic Triple-Negative Breast Cancer
(BASEC)
Eligible are adults aged ≥ 18 years with locally advanced, inoperable or metastatic triple-negative breast cancer who have not received prior systemic therapy for advanced disease and whose tumors are PD-L1-negative at the time of assessment. Alternatively, patients whose tumors are PD-L1-positive at the time of assessment may be eligible if they have received an anti-PD-(L)1 inhibitor (i.e., a checkpoint inhibitor) in the adjuvant or neoadjuvant setting. Patients must have completed treatment for breast cancer at stage I-III, if indicated, and at least 6 months must have elapsed between the completion of curative intent treatment and the first documented local or distant recurrence of the disease. Patients with de novo metastatic TNBC are eligible for this study; tumors will be centrally assessed for TNBC and PD-L1 status. (BASEC)
Criteri di esclusione
Positive serum pregnancy test or women who are breastfeeding, known or severe hypersensitivity or allergy to Sacituzumab Govitecan and/or the chemotherapy regimen of choice in the TPC arm, requirement for ongoing therapy with or prior use of prohibited medications. Patients must not have received systemic cancer treatment within the last 6 months or radiation therapy within the 2 weeks prior to study enrollment. Patients must have recovered from any side effects attributable to a previously administered drug at the time of study enrollment. Patients must not have participated in a study with an investigational drug or device within 4 weeks prior to randomization. Patients who have previously received Topoisomerase-1 inhibitors or antibody-drug conjugates containing a Topoisomerase inhibitor are excluded. (BASEC)
