Study Endpoints

Primary Endpoints

Progression Free Survival
Assessed at baseline and every 3 cycles/9 weeks with a window of -7 days to + 3 days (e.g., between Cycle 3 Day 15 and Cycle 4 Day 4). Expected study duration to primary analysis of PFS is 38 months. The reported data is as of data cutoff of 3/9/2024.

Compare the progression-free survival (PFS) of sacituzumab govitecan with pembrolizumab to that of sacituzumab govitecan alone. PFS is defined as the time from study randomization to disease progression, according to RECIST 1.1 or medical judgment, the latter based on established clinical parameters, such as rising tumor markers and physical exam evidence of progression, i.e. worsening chest wall disease, or death due to any cause, whichever occurred first. Patients alive without disease progression are censored at the date of last disease evaluation.

Secondary Endpoints

Objective Response Rate
Assessed at baseline and every 3 cycles/9 weeks with a window of -7 days to + 3 days (e.g., between Cycle 3 Day 15 and Cycle 4 Day 4). Expected study duration is 38 months. The reported data is as of data cutoff of 3/9/2024.
Overall Survival
Assessed at baseline and every 3 cycles/9 weeks with a window of -7 days to + 3 days (e.g., between Cycle 3 Day 15 and Cycle 4 Day 4). Expected study duration is 38 months. The reported data is as of data cutoff of 3/9/2024.
Clinical Benefit Rate
Assessed at baseline and every 3 cycles/9 weeks with a window of -7 days to + 3 days (e.g., between Cycle 3 Day 15 and Cycle 4 Day 4). Expected study duration is 38 months. The reported data is as of data cutoff of 3/9/2024.

RetreatmentEXPERIMENTALParticipants who have attained a confirmed complete response (CR) who have been treated for at least 24 weeks on protocol therapy and had at least three cycles (with pembrolizumab and sacituzumab govitecan (Arm A) or sacituzumab govitecan alone (Arm B)) beyond the date when the initial CR was declared may be eligible for additional sacituzumab govitecan and/or pembrolizumab therapy if they progress after stopping study treatment. This retreatment is termed the Second Course Phase of this study and is only available if the study remains open and the subject meets protocol-specified conditions.

Frequently asked questions about Pembrolizumab

What is Pembrolizumab used for in Invasive Breast Cancer?

Pembrolizumab is being studied in a Phase 2 clinical trial for the treatment of Invasive Breast Cancer, specifically in patients with HR-positive, HER2-negative metastatic breast cancer. The trial evaluates pembrolizumab in combination with sacituzumab govitecan compared to sacituzumab govitecan alone. The study is active but not recruiting participants.

What does Pembrolizumab target?

Pembrolizumab targets PDCD1, also known as programmed cell death protein 1, and acts as an inhibitor of this target. By inhibiting PDCD1, pembrolizumab is designed to modulate the immune system's response to cancer cells. This mechanism is being investigated in the context of invasive breast cancer in an ongoing Phase 2 clinical trial.

Who makes Pembrolizumab?

Pembrolizumab is developed by Gilead Sciences, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol GILD. The drug is being investigated in a Phase 2 clinical trial for invasive breast cancer, with the trial sponsored by the developer.

What phase is Pembrolizumab in?

Pembrolizumab is in Phase 2 clinical development for the treatment of Invasive Breast Cancer. It is an investigational drug in this indication and has not been approved for this use. The ongoing Phase 2 trial is active but not recruiting, with an enrollment of 110 participants.

What clinical trials is Pembrolizumab in?

Pembrolizumab is involved in one active clinical trial with the identifier NCT04448886. This Phase 2 trial, titled 'Sacituzumab Govitecan +/- Pembrolizumab In HR+ / HER2 - MBC', is investigating pembrolizumab in combination with sacituzumab govitecan for HR-positive, HER2-negative metastatic breast cancer. The trial is being conducted in the United States and enrolls adults aged 18 years and older.

Is Pembrolizumab the same as KEYTRUDA?

Yes, Pembrolizumab is the same as KEYTRUDA, which is a brand name for the drug. The alternative name for pembrolizumab is 'Pembrolizumab 25 mg/1 ML Intravenous Solution [KEYTRUDA]'. In clinical trials, the drug is referred to as pembrolizumab, and it is being studied for use in invasive breast cancer.
